=================
Seamless printing to the terminal (stdout) and logging to a io.Writer
(file) that’s as easy to use as fmt.Println.
Graphic by [JonnyEtc](http://jonnyetc.deviantart.com/art/And-That-s-Why-You-Always-Leave-a-Note-315311422)
JWW is primarily a wrapper around the excellent standard log library. It
provides a few advantages over using the standard log library alone.
1. Ready to go out of the box.
2. One library for both printing to the terminal and logging (to files).
3. Really easy to log to either a temp file or a file you specify.
I really wanted a very straightforward library that could seamlessly do
the following things.
1. Replace all the println, printf, etc statements thoughout my code with
something more useful
2. Allow the user to easily control what levels are printed to stdout
3. Allow the user to easily control what levels are logged
4. Provide an easy mechanism (like fmt.Println) to print info to the user
which can be easily logged as well
5. Due to 2 & 3 provide easy verbose mode for output and logs
6. Not have any unnecessary initialization cruft. Just use it.
# Usage
## Step 1. Use it
Put calls throughout your source based on type of feedback.
No initialization or setup needs to happen. Just start calling things.
Available Loggers are:
* TRACE
* DEBUG
* INFO
* WARN
* ERROR
* CRITICAL
* FATAL
These each are loggers based on the log standard library and follow the
standard usage. Eg.
```go
import (
jww "github.com/spf13/jwalterweatherman"
)
...
if err != nil {
// This is a pretty serious error and the user should know about
// it. It will be printed to the terminal as well as logged under the
// default thresholds.
jww.ERROR.Println(err)
}
if err2 != nil {
// This error isn’t going to materially change the behavior of the
// application, but it’s something that may not be what the user
// expects. Under the default thresholds, Warn will be logged, but
// not printed to the terminal.
jww.WARN.Println(err2)
}
// Information that’s relevant to what’s happening, but not very
// important for the user. Under the default thresholds this will be
// discarded.
jww.INFO.Printf("information %q", response)
```
NOTE: You can also use the library in a non-global setting by creating an instance of a Notebook:
```go
notepad = jww.NewNotepad(jww.LevelInfo, jww.LevelTrace, os.Stdout, ioutil.Discard, "", log.Ldate|log.Ltime)
notepad.WARN.Println("Some warning"")
```
_Why 7 levels?_
Maybe you think that 7 levels are too much for any application... and you
are probably correct. Just because there are seven levels doesn’t mean
that you should be using all 7 levels. Pick the right set for your needs.
Remember they only have to mean something to your project.
## Step 2. Optionally configure JWW
Under the default thresholds :
* Debug, Trace & Info goto /dev/null
* Warn and above is logged (when a log file/io.Writer is provided)
* Error and above is printed to the terminal (stdout)
### Changing the thresholds
The threshold can be changed at any time, but will only affect calls that
execute after the change was made.
This is very useful if your application has a verbose mode. Of course you
can decide what verbose means to you or even have multiple levels of
verbosity.
```go
import (
jww "github.com/spf13/jwalterweatherman"
)
if Verbose {
jww.SetLogThreshold(jww.LevelTrace)
jww.SetStdoutThreshold(jww.LevelInfo)
}
```
Note that JWW's own internal output uses log levels as well, so set the log
level before making any other calls if you want to see what it's up to.
### Setting a log file
JWW can log to any `io.Writer`:
```go
jww.SetLogOutput(customWriter)
```
# More information
This is an early release. I’ve been using it for a while and this is the
third interface I’ve tried. I like this one pretty well, but no guarantees
that it won’t change a bit.
I wrote this for use in [hugo](https://gohugo.io). If you are looking
for a static website engine that’s super fast please checkout Hugo.

# Generating shell completions
Cobra can generate shell completions for multiple shells.
The currently supported shells are:
- Bash
- Zsh
- fish
- PowerShell
Cobra will automatically provide your program with a fully functional `completion` command,
similarly to how it provides the `help` command.
## Creating your own completion command
If you do not wish to use the default `completion` command, you can choose to
provide your own, which will take precedence over the default one. (This also provides
backwards-compatibility with programs that already have their own `completion` command.)
If you are using the generator, you can create a completion command by running
```bash
cobra add completion
```
and then modifying the generated `cmd/completion.go` file to look something like this
(writing the shell script to stdout allows the most flexible use):
```go
var completionCmd = &cobra.Command{
Use: "completion [bash|zsh|fish|powershell]",
Short: "Generate completion script",
Long: fmt.Sprintf(`To load completions:
Bash:
$ source <(%[1]s completion bash)
# To load completions for each session, execute once:
# Linux:
$ %[1]s completion bash > /etc/bash_completion.d/%[1]s
# macOS:
$ %[1]s completion bash > /usr/local/etc/bash_completion.d/%[1]s
Zsh:
# If shell completion is not already enabled in your environment,
# you will need to enable it. You can execute the following once:
$ echo "autoload -U compinit; compinit" >> ~/.zshrc
# To load completions for each session, execute once:
$ %[1]s completion zsh > "${fpath[1]}/_%[1]s"
# You will need to start a new shell for this setup to take effect.
fish:
$ %[1]s completion fish | source
# To load completions for each session, execute once:
$ %[1]s completion fish > ~/.config/fish/completions/%[1]s.fish
PowerShell:
PS> %[1]s completion powershell | Out-String | Invoke-Expression
# To load completions for every new session, run:
PS> %[1]s completion powershell > %[1]s.ps1
# and source this file from your PowerShell profile.
`,cmd.Root().Name()),
DisableFlagsInUseLine: true,
ValidArgs: []string{"bash", "zsh", "fish", "powershell"},
Args: cobra.ExactValidArgs(1),
Run: func(cmd *cobra.Command, args []string) {
switch args[0] {
case "bash":
cmd.Root().GenBashCompletion(os.Stdout)
case "zsh":
cmd.Root().GenZshCompletion(os.Stdout)
case "fish":
cmd.Root().GenFishCompletion(os.Stdout, true)
case "powershell":
cmd.Root().GenPowerShellCompletionWithDesc(os.Stdout)
}
},
}
```
**Note:** The cobra generator may include messages printed to stdout, for example, if the config file is loaded; this will break the auto-completion script so must be removed.
## Adapting the default completion command
Cobra provides a few options for the default `completion` command. To configure such options you must set
the `CompletionOptions` field on the *root* command.
To tell Cobra *not* to provide the default `completion` command:
```
rootCmd.CompletionOptions.DisableDefaultCmd = true
```
To tell Cobra *not* to provide the user with the `--no-descriptions` flag to the completion sub-commands:
```
rootCmd.CompletionOptions.DisableNoDescFlag = true
```
To tell Cobra to completely disable descriptions for completions:
```
rootCmd.CompletionOptions.DisableDescriptions = true
```
# Customizing completions
The generated completion scripts will automatically handle completing commands and flags. However, you can make your completions much more powerful by providing information to complete your program's nouns and flag values.
## Completion of nouns
### Static completion of nouns
Cobra allows you to provide a pre-defined list of completion choices for your nouns using the `ValidArgs` field.
For example, if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them.
Some simplified code from `kubectl get` looks like:
```go
validArgs []string = { "pod", "node", "service", "replicationcontroller" }
cmd := &cobra.Command{
Use: "get [(-o|--output=)json|yaml|template|...] (RESOURCE [NAME] | RESOURCE/NAME ...)",
Short: "Display one or many resources",
Long: get_long,
Example: get_example,
Run: func(cmd *cobra.Command, args []string) {
cobra.CheckErr(RunGet(f, out, cmd, args))
},
ValidArgs: validArgs,
}
```
Notice we put the `ValidArgs` field on the `get` sub-command. Doing so will give results like:
```bash
$ kubectl get [tab][tab]
node pod replicationcontroller service
```
#### Aliases for nouns
If your nouns have aliases, you can define them alongside `ValidArgs` using `ArgAliases`:
```go
argAliases []string = { "pods", "nodes", "services", "svc", "replicationcontrollers", "rc" }
cmd := &cobra.Command{
...
ValidArgs: validArgs,
ArgAliases: argAliases
}
```
The aliases are not shown to the user on tab completion, but they are accepted as valid nouns by
the completion algorithm if entered manually, e.g. in:
```bash
$ kubectl get rc [tab][tab]
backend frontend database
```
Note that without declaring `rc` as an alias, the completion algorithm would not know to show the list of
replication controllers following `rc`.
### Dynamic completion of nouns
In some cases it is not possible to provide a list of completions in advance. Instead, the list of completions must be determined at execution-time. In a similar fashion as for static completions, you can use the `ValidArgsFunction` field to provide a Go function that Cobra will execute when it needs the list of completion choices for the nouns of a command. Note that either `ValidArgs` or `ValidArgsFunction` can be used for a single cobra command, but not both.
Simplified code from `helm status` looks like:
```go
cmd := &cobra.Command{
Use: "status RELEASE_NAME",
Short: "Display the status of the named release",
Long: status_long,
RunE: func(cmd *cobra.Command, args []string) {
RunGet(args[0])
},
ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
if len(args) != 0 {
return nil, cobra.ShellCompDirectiveNoFileComp
}
return getReleasesFromCluster(toComplete), cobra.ShellCompDirectiveNoFileComp
},
}
```
Where `getReleasesFromCluster()` is a Go function that obtains the list of current Helm releases running on the Kubernetes cluster.
Notice we put the `ValidArgsFunction` on the `status` sub-command. Let's assume the Helm releases on the cluster are: `harbor`, `notary`, `rook` and `thanos` then this dynamic completion will give results like:
```bash
$ helm status [tab][tab]
harbor notary rook thanos
```
You may have noticed the use of `cobra.ShellCompDirective`. These directives are bit fields allowing to control some shell completion behaviors for your particular completion. You can combine them with the bit-or operator such as `cobra.ShellCompDirectiveNoSpace | cobra.ShellCompDirectiveNoFileComp`
```go
// Indicates that the shell will perform its default behavior after completions
// have been provided (this implies none of the other directives).
ShellCompDirectiveDefault
// Indicates an error occurred and completions should be ignored.
ShellCompDirectiveError
// Indicates that the shell should not add a space after the completion,
// even if there is a single completion provided.
ShellCompDirectiveNoSpace
// Indicates that the shell should not provide file completion even when
// no completion is provided.
ShellCompDirectiveNoFileComp
// Indicates that the returned completions should be used as file extension filters.
// For example, to complete only files of the form *.json or *.yaml:
// return []string{"yaml", "json"}, ShellCompDirectiveFilterFileExt
// For flags, using MarkFlagFilename() and MarkPersistentFlagFilename()
// is a shortcut to using this directive explicitly.
//
ShellCompDirectiveFilterFileExt
// Indicates that only directory names should be provided in file completion.
// For example:
// return nil, ShellCompDirectiveFilterDirs
// For flags, using MarkFlagDirname() is a shortcut to using this directive explicitly.
//
// To request directory names within another directory, the returned completions
// should specify a single directory name within which to search. For example,
// to complete directories within "themes/":
// return []string{"themes"}, ShellCompDirectiveFilterDirs
//
ShellCompDirectiveFilterDirs
```
***Note***: When using the `ValidArgsFunction`, Cobra will call your registered function after having parsed all flags and arguments provided in the command-line. You therefore don't need to do this parsing yourself. For example, when a user calls `helm status --namespace my-rook-ns [tab][tab]`, Cobra will call your registered `ValidArgsFunction` after having parsed the `--namespace` flag, as it would have done when calling the `RunE` function.
#### Debugging
Cobra achieves dynamic completion through the use of a hidden command called by the completion script. To debug your Go completion code, you can call this hidden command directly:
```bash
$ helm __complete status har<ENTER>
harbor
:4
Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
```
***Important:*** If the noun to complete is empty (when the user has not yet typed any letters of that noun), you must pass an empty parameter to the `__complete` command:
```bash
$ helm __complete status ""<ENTER>
harbor
notary
rook
thanos
:4
Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
```
Calling the `__complete` command directly allows you to run the Go debugger to troubleshoot your code. You can also add printouts to your code; Cobra provides the following functions to use for printouts in Go completion code:
```go
// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
// is set to a file path) and optionally prints to stderr.
cobra.CompDebug(msg string, printToStdErr bool) {
cobra.CompDebugln(msg string, printToStdErr bool)
// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
// is set to a file path) and to stderr.
cobra.CompError(msg string)
cobra.CompErrorln(msg string)
```
***Important:*** You should **not** leave traces that print directly to stdout in your completion code as they will be interpreted as completion choices by the completion script. Instead, use the cobra-provided debugging traces functions mentioned above.
## Completions for flags
### Mark flags as required
Most of the time completions will only show sub-commands. But if a flag is required to make a sub-command work, you probably want it to show up when the user types [tab][tab]. You can mark a flag as 'Required' like so:
```go
cmd.MarkFlagRequired("pod")
cmd.MarkFlagRequired("container")
```
and you'll get something like
```bash
$ kubectl exec [tab][tab]
-c --container= -p --pod=
```
### Specify dynamic flag completion
As for nouns, Cobra provides a way of defining dynamic completion of flags. To provide a Go function that Cobra will execute when it needs the list of completion choices for a flag, you must register the function using the `command.RegisterFlagCompletionFunc()` function.
```go
flagName := "output"
cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
return []string{"json", "table", "yaml"}, cobra.ShellCompDirectiveDefault
})
```
Notice that calling `RegisterFlagCompletionFunc()` is done through the `command` with which the flag is associated. In our example this dynamic completion will give results like so:
```bash
$ helm status --output [tab][tab]
json table yaml
```
#### Debugging
You can also easily debug your Go completion code for flags:
```bash
$ helm __complete status --output ""
json
table
yaml
:4
Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
```
***Important:*** You should **not** leave traces that print to stdout in your completion code as they will be interpreted as completion choices by the completion script. Instead, use the cobra-provided debugging traces functions mentioned further above.
### Specify valid filename extensions for flags that take a filename
To limit completions of flag values to file names with certain extensions you can either use the different `MarkFlagFilename()` functions or a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterFileExt`, like so:
```go
flagName := "output"
cmd.MarkFlagFilename(flagName, "yaml", "json")
```
or
```go
flagName := "output"
cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
return []string{"yaml", "json"}, ShellCompDirectiveFilterFileExt})
```
### Limit flag completions to directory names
To limit completions of flag values to directory names you can either use the `MarkFlagDirname()` functions or a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterDirs`, like so:
```go
flagName := "output"
cmd.MarkFlagDirname(flagName)
```
or
```go
flagName := "output"
cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
return nil, cobra.ShellCompDirectiveFilterDirs
})
```
To limit completions of flag values to directory names *within another directory* you can use a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterDirs` like so:
```go
flagName := "output"
cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
return []string{"themes"}, cobra.ShellCompDirectiveFilterDirs
})
```
### Descriptions for completions
Cobra provides support for completion descriptions. Such descriptions are supported for each shell
(however, for bash, it is only available in the [completion V2 version](#bash-completion-v2)).
For commands and flags, Cobra will provide the descriptions automatically, based on usage information.
For example, using zsh:
```
$ helm s[tab]
search -- search for a keyword in charts
show -- show information of a chart
status -- displays the status of the named release
```
while using fish:
```
$ helm s[tab]
search (search for a keyword in charts) show (show information of a chart) status (displays the status of the named release)
```
Cobra allows you to add descriptions to your own completions. Simply add the description text after each completion, following a `\t` separator. This technique applies to completions returned by `ValidArgs`, `ValidArgsFunction` and `RegisterFlagCompletionFunc()`. For example:
```go
ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
return []string{"harbor\tAn image registry", "thanos\tLong-term metrics"}, cobra.ShellCompDirectiveNoFileComp
}}
```
or
```go
ValidArgs: []string{"bash\tCompletions for bash", "zsh\tCompletions for zsh"}
```
## Bash completions
### Dependencies
The bash completion script generated by Cobra requires the `bash_completion` package. You should update the help text of your completion command to show how to install the `bash_completion` package ([Kubectl docs](https://kubernetes.io/docs/tasks/tools/install-kubectl/#enabling-shell-autocompletion))
### Aliases
You can also configure `bash` aliases for your program and they will also support completions.
```bash
alias aliasname=origcommand
complete -o default -F __start_origcommand aliasname
# and now when you run `aliasname` completion will make
# suggestions as it did for `origcommand`.
$ aliasname <tab><tab>
completion firstcommand secondcommand
```
### Bash legacy dynamic completions
For backward compatibility, Cobra still supports its bash legacy dynamic completion solution.
Please refer to [Bash Completions](bash_completions.md) for details.
### Bash completion V2
Cobra provides two versions for bash completion. The original bash completion (which started it all!) can be used by calling
`GenBashCompletion()` or `GenBashCompletionFile()`.
A new V2 bash completion version is also available. This version can be used by calling `GenBashCompletionV2()` or
`GenBashCompletionFileV2()`. The V2 version does **not** support the legacy dynamic completion
(see [Bash Completions](bash_completions.md)) but instead works only with the Go dynamic completion
solution described in this document.
Unless your program already uses the legacy dynamic completion solution, it is recommended that you use the bash
completion V2 solution which provides the following extra features:
- Supports completion descriptions (like the other shells)
- Small completion script of less than 300 lines (v1 generates scripts of thousands of lines; `kubectl` for example has a bash v1 completion script of over 13K lines)
- Streamlined user experience thanks to a completion behavior aligned with the other shells
`Bash` completion V2 supports descriptions for completions. When calling `GenBashCompletionV2()` or `GenBashCompletionFileV2()`
you must provide these functions with a parameter indicating if the completions should be annotated with a description; Cobra
will provide the description automatically based on usage information. You can choose to make this option configurable by
your users.
```
# With descriptions
$ helm s[tab][tab]
search (search for a keyword in charts) status (display the status of the named release)
show (show information of a chart)
# Without descriptions
$ helm s[tab][tab]
search show status
```
**Note**: Cobra's default `completion` command uses bash completion V2. If for some reason you need to use bash completion V1, you will need to implement your own `completion` command.
## Zsh completions
Cobra supports native zsh completion generated from the root `cobra.Command`.
The generated completion script should be put somewhere in your `$fpath` and be named
`_<yourProgram>`. You will need to start a new shell for the completions to become available.
Zsh supports descriptions for completions. Cobra will provide the description automatically,
based on usage information. Cobra provides a way to completely disable such descriptions by
using `GenZshCompletionNoDesc()` or `GenZshCompletionFileNoDesc()`. You can choose to make
this a configurable option to your users.
```
# With descriptions
$ helm s[tab]
search -- search for a keyword in charts
show -- show information of a chart
status -- displays the status of the named release
# Without descriptions
$ helm s[tab]
search show status
```
*Note*: Because of backward-compatibility requirements, we were forced to have a different API to disable completion descriptions between `zsh` and `fish`.
### Limitations
* Custom completions implemented in Bash scripting (legacy) are not supported and will be ignored for `zsh` (including the use of the `BashCompCustom` flag annotation).
* You should instead use `ValidArgsFunction` and `RegisterFlagCompletionFunc()` which are portable to the different shells (`bash`, `zsh`, `fish`, `powershell`).
* The function `MarkFlagCustom()` is not supported and will be ignored for `zsh`.
* You should instead use `RegisterFlagCompletionFunc()`.
### Zsh completions standardization
Cobra 1.1 standardized its zsh completion support to align it with its other shell completions. Although the API was kept backward-compatible, some small changes in behavior were introduced.
Please refer to [Zsh Completions](zsh_completions.md) for details.
## fish completions
Cobra supports native fish completions generated from the root `cobra.Command`. You can use the `command.GenFishCompletion()` or `command.GenFishCompletionFile()` functions. You must provide these functions with a parameter indicating if the completions should be annotated with a description; Cobra will provide the description automatically based on usage information. You can choose to make this option configurable by your users.
```
# With descriptions
$ helm s[tab]
search (search for a keyword in charts) show (show information of a chart) status (displays the status of the named release)
# Without descriptions
$ helm s[tab]
search show status
```
*Note*: Because of backward-compatibility requirements, we were forced to have a different API to disable completion descriptions between `zsh` and `fish`.
### Limitations
* Custom completions implemented in bash scripting (legacy) are not supported and will be ignored for `fish` (including the use of the `BashCompCustom` flag annotation).
* You should instead use `ValidArgsFunction` and `RegisterFlagCompletionFunc()` which are portable to the different shells (`bash`, `zsh`, `fish`, `powershell`).
* The function `MarkFlagCustom()` is not supported and will be ignored for `fish`.
* You should instead use `RegisterFlagCompletionFunc()`.
* The following flag completion annotations are not supported and will be ignored for `fish`:
* `BashCompFilenameExt` (filtering by file extension)
* `BashCompSubdirsInDir` (filtering by directory)
* The functions corresponding to the above annotations are consequently not supported and will be ignored for `fish`:
* `MarkFlagFilename()` and `MarkPersistentFlagFilename()` (filtering by file extension)
* `MarkFlagDirname()` and `MarkPersistentFlagDirname()` (filtering by directory)
* Similarly, the following completion directives are not supported and will be ignored for `fish`:
* `ShellCompDirectiveFilterFileExt` (filtering by file extension)
* `ShellCompDirectiveFilterDirs` (filtering by directory)
## PowerShell completions
Cobra supports native PowerShell completions generated from the root `cobra.Command`. You can use the `command.GenPowerShellCompletion()` or `command.GenPowerShellCompletionFile()` functions. To include descriptions use `command.GenPowerShellCompletionWithDesc()` and `command.GenPowerShellCompletionFileWithDesc()`. Cobra will provide the description automatically based on usage information. You can choose to make this option configurable by your users.
The script is designed to support all three PowerShell completion modes:
* TabCompleteNext (default windows style - on each key press the next option is displayed)
* Complete (works like bash)
* MenuComplete (works like zsh)
You set the mode with `Set-PSReadLineKeyHandler -Key Tab -Function <mode>`. Descriptions are only displayed when using the `Complete` or `MenuComplete` mode.
Users need PowerShell version 5.0 or above, which comes with Windows 10 and can be downloaded separately for Windows 7 or 8.1. They can then write the completions to a file and source this file from their PowerShell profile, which is referenced by the `$Profile` environment variable. See `Get-Help about_Profiles` for more info about PowerShell profiles.
```
# With descriptions and Mode 'Complete'
$ helm s[tab]
search (search for a keyword in charts) show (show information of a chart) status (displays the status of the named release)
# With descriptions and Mode 'MenuComplete' The description of the current selected value will be displayed below the suggestions.
$ helm s[tab]
search show status
search for a keyword in charts
# Without descriptions
$ helm s[tab]
search show status
```
### Limitations
* Custom completions implemented in bash scripting (legacy) are not supported and will be ignored for `powershell` (including the use of the `BashCompCustom` flag annotation).
* You should instead use `ValidArgsFunction` and `RegisterFlagCompletionFunc()` which are portable to the different shells (`bash`, `zsh`, `fish`, `powershell`).
* The function `MarkFlagCustom()` is not supported and will be ignored for `powershell`.
* You should instead use `RegisterFlagCompletionFunc()`.
* The following flag completion annotations are not supported and will be ignored for `powershell`:
* `BashCompFilenameExt` (filtering by file extension)
* `BashCompSubdirsInDir` (filtering by directory)
* The functions corresponding to the above annotations are consequently not supported and will be ignored for `powershell`:
* `MarkFlagFilename()` and `MarkPersistentFlagFilename()` (filtering by file extension)
* `MarkFlagDirname()` and `MarkPersistentFlagDirname()` (filtering by directory)
* Similarly, the following completion directives are not supported and will be ignored for `powershell`:
* `ShellCompDirectiveFilterFileExt` (filtering by file extension)
* `ShellCompDirectiveFilterDirs` (filtering by directory)

## Generating Zsh Completion For Your cobra.Command
Please refer to [Shell Completions](shell_completions.md) for details.
## Zsh completions standardization
Cobra 1.1 standardized its zsh completion support to align it with its other shell completions. Although the API was kept backwards-compatible, some small changes in behavior were introduced.
### Deprecation summary
See further below for more details on these deprecations.
* `cmd.MarkZshCompPositionalArgumentFile(pos, []string{})` is no longer needed. It is therefore **deprecated** and silently ignored.
* `cmd.MarkZshCompPositionalArgumentFile(pos, glob[])` is **deprecated** and silently ignored.
* Instead use `ValidArgsFunction` with `ShellCompDirectiveFilterFileExt`.
* `cmd.MarkZshCompPositionalArgumentWords()` is **deprecated** and silently ignored.
* Instead use `ValidArgsFunction`.
### Behavioral changes
**Noun completion**
|Old behavior|New behavior|
|---|---|
|No file completion by default (opposite of bash)|File completion by default; use `ValidArgsFunction` with `ShellCompDirectiveNoFileComp` to turn off file completion on a per-argument basis|
|Completion of flag names without the `-` prefix having been typed|Flag names are only completed if the user has typed the first `-`|
`cmd.MarkZshCompPositionalArgumentFile(pos, []string{})` used to turn on file completion on a per-argument position basis|File completion for all arguments by default; `cmd.MarkZshCompPositionalArgumentFile()` is **deprecated** and silently ignored|
|`cmd.MarkZshCompPositionalArgumentFile(pos, glob[])` used to turn on file completion **with glob filtering** on a per-argument position basis (zsh-specific)|`cmd.MarkZshCompPositionalArgumentFile()` is **deprecated** and silently ignored; use `ValidArgsFunction` with `ShellCompDirectiveFilterFileExt` for file **extension** filtering (not full glob filtering)|
|`cmd.MarkZshCompPositionalArgumentWords(pos, words[])` used to provide completion choices on a per-argument position basis (zsh-specific)|`cmd.MarkZshCompPositionalArgumentWords()` is **deprecated** and silently ignored; use `ValidArgsFunction` to achieve the same behavior|
**Flag-value completion**
|Old behavior|New behavior|
|---|---|
|No file completion by default (opposite of bash)|File completion by default; use `RegisterFlagCompletionFunc()` with `ShellCompDirectiveNoFileComp` to turn off file completion|
|`cmd.MarkFlagFilename(flag, []string{})` and similar used to turn on file completion|File completion by default; `cmd.MarkFlagFilename(flag, []string{})` no longer needed in this context and silently ignored|
|`cmd.MarkFlagFilename(flag, glob[])` used to turn on file completion **with glob filtering** (syntax of `[]string{"*.yaml", "*.yml"}` incompatible with bash)|Will continue to work, however, support for bash syntax is added and should be used instead so as to work for all shells (`[]string{"yaml", "yml"}`)|
|`cmd.MarkFlagDirname(flag)` only completes directories (zsh-specific)|Has been added for all shells|
|Completion of a flag name does not repeat, unless flag is of type `*Array` or `*Slice` (not supported by bash)|Retained for `zsh` and added to `fish`|
|Completion of a flag name does not provide the `=` form (unlike bash)|Retained for `zsh` and added to `fish`|
**Improvements**
* Custom completion support (`ValidArgsFunction` and `RegisterFlagCompletionFunc()`)
* File completion by default if no other completions found
* Handling of required flags
* File extension filtering no longer mutually exclusive with bash usage
* Completion of directory names *within* another directory
* Support for `=` form of flags

Cobra is both a library for creating powerful modern CLI applications as well as a program to generate applications and command files.
Cobra is used in many Go projects such as [Kubernetes](http://kubernetes.io/),
[Hugo](https://gohugo.io), and [Github CLI](https://github.com/cli/cli) to
name a few. [This list](./projects_using_cobra.md) contains a more extensive list of projects using Cobra.
[](https://github.com/spf13/cobra/actions?query=workflow%3ATest)
[](https://godoc.org/github.com/spf13/cobra)
[](https://goreportcard.com/report/github.com/spf13/cobra)
[](https://gophers.slack.com/archives/CD3LP1199)
# Overview
Cobra is a library providing a simple interface to create powerful modern CLI
interfaces similar to git & go tools.
Cobra is also an application that will generate your application scaffolding to rapidly
develop a Cobra-based application.
Cobra provides:
* Easy subcommand-based CLIs: `app server`, `app fetch`, etc.
* Fully POSIX-compliant flags (including short & long versions)
* Nested subcommands
* Global, local and cascading flags
* Easy generation of applications & commands with `cobra init` & `cobra add cmdname`
* Intelligent suggestions (`app srver`... did you mean `app server`?)
* Automatic help generation for commands and flags
* Automatic help flag recognition of `-h`, `--help`, etc.
* Automatically generated shell autocomplete for your application (bash, zsh, fish, powershell)
* Automatically generated man pages for your application
* Command aliases so you can change things without breaking them
* The flexibility to define your own help, usage, etc.
* Optional seamless integration with [viper](http://github.com/spf13/viper) for 12-factor apps
# Concepts
Cobra is built on a structure of commands, arguments & flags.
**Commands** represent actions, **Args** are things and **Flags** are modifiers for those actions.
The best applications read like sentences when used, and as a result, users
intuitively know how to interact with them.
The pattern to follow is
`APPNAME VERB NOUN --ADJECTIVE.`
or
`APPNAME COMMAND ARG --FLAG`
A few good real world examples may better illustrate this point.
In the following example, 'server' is a command, and 'port' is a flag:
hugo server --port=1313
In this command we are telling Git to clone the url bare.
git clone URL --bare
## Commands
Command is the central point of the application. Each interaction that
the application supports will be contained in a Command. A command can
have children commands and optionally run an action.
In the example above, 'server' is the command.
[More about cobra.Command](https://pkg.go.dev/github.com/spf13/cobra#Command)
## Flags
A flag is a way to modify the behavior of a command. Cobra supports
fully POSIX-compliant flags as well as the Go [flag package](https://golang.org/pkg/flag/).
A Cobra command can define flags that persist through to children commands
and flags that are only available to that command.
In the example above, 'port' is the flag.
Flag functionality is provided by the [pflag
library](https://github.com/spf13/pflag), a fork of the flag standard library
which maintains the same interface while adding POSIX compliance.
# Installing
Using Cobra is easy. First, use `go get` to install the latest version
of the library. This command will install the `cobra` generator executable
along with the library and its dependencies:
go get -u github.com/spf13/cobra
Next, include Cobra in your application:
```go
import "github.com/spf13/cobra"
```
# Usage
Cobra provides its own program that will create your application and add any
commands you want. It's the easiest way to incorporate Cobra into your application.
For complete details on using the Cobra generator, please read [The Cobra Generator README](https://github.com/spf13/cobra/blob/master/cobra/README.md)
For complete details on using the Cobra library, please read the [The Cobra User Guide](user_guide.md).

# Cobra Changelog
## v1.1.3
* **Fix:** release-branch.cobra1.1 only: Revert "Deprecate Go < 1.14" to maintain backward compatibility
## v1.1.2
### Notable Changes
* Bump license year to 2021 in golden files (#1309) @Bowbaq
* Enhance PowerShell completion with custom comp (#1208) @Luap99
* Update gopkg.in/yaml.v2 to v2.4.0: The previous breaking change in yaml.v2 v2.3.0 has been reverted, see go-yaml/yaml#670
* Documentation readability improvements (#1228 etc.) @zaataylor etc.
* Use golangci-lint: Repair warnings and errors resulting from linting (#1044) @umarcor
## v1.1.1
* **Fix:** yaml.v2 2.3.0 contained a unintended breaking change. This release reverts to yaml.v2 v2.2.8 which has recent critical CVE fixes, but does not have the breaking changes. See https://github.com/spf13/cobra/pull/1259 for context.
* **Fix:** correct internal formatting for go-md2man v2 (which caused man page generation to be broken). See https://github.com/spf13/cobra/issues/1049 for context.
## v1.1.0
### Notable Changes
* Extend Go completions and revamp zsh comp (#1070)
* Fix man page doc generation - no auto generated tag when `cmd.DisableAutoGenTag = true` (#1104) @jpmcb
* Add completion for help command (#1136)
* Complete subcommands when TraverseChildren is set (#1171)
* Fix stderr printing functions (#894)
* fix: fish output redirection (#1247)
## v1.0.0
Announcing v1.0.0 of Cobra. 🎉
### Notable Changes
* Fish completion (including support for Go custom completion) @marckhouzam
* API (urgent): Rename BashCompDirectives to ShellCompDirectives @marckhouzam
* Remove/replace SetOutput on Command - deprecated @jpmcb
* add support for autolabel stale PR @xchapter7x
* Add Labeler Actions @xchapter7x
* Custom completions coded in Go (instead of Bash) @marckhouzam
* Partial Revert of #922 @jharshman
* Add Makefile to project @jharshman
* Correct documentation for InOrStdin @desponda
* Apply formatting to templates @jharshman
* Revert change so help is printed on stdout again @marckhouzam
* Update md2man to v2.0.0 @pdf
* update viper to v1.4.0 @umarcor
* Update cmd/root.go example in README.md @jharshman

# User Guide
While you are welcome to provide your own organization, typically a Cobra-based
application will follow the following organizational structure:
```
▾ appName/
▾ cmd/
add.go
your.go
commands.go
here.go
main.go
```
In a Cobra app, typically the main.go file is very bare. It serves one purpose: initializing Cobra.
```go
package main
import (
"{pathToYourApp}/cmd"
)
func main() {
cmd.Execute()
}
```
## Using the Cobra Generator
Cobra provides its own program that will create your application and add any
commands you want. It's the easiest way to incorporate Cobra into your application.
For complete details on using the Cobra generator, please read [The Cobra Generator README](https://github.com/spf13/cobra/blob/master/cobra/README.md)
## Using the Cobra Library
To manually implement Cobra you need to create a bare main.go file and a rootCmd file.
You will optionally provide additional commands as you see fit.
### Create rootCmd
Cobra doesn't require any special constructors. Simply create your commands.
Ideally you place this in app/cmd/root.go:
```go
var rootCmd = &cobra.Command{
Use: "hugo",
Short: "Hugo is a very fast static site generator",
Long: `A Fast and Flexible Static Site Generator built with
love by spf13 and friends in Go.
Complete documentation is available at http://hugo.spf13.com`,
Run: func(cmd *cobra.Command, args []string) {
// Do Stuff Here
},
}
func Execute() {
if err := rootCmd.Execute(); err != nil {
fmt.Fprintln(os.Stderr, err)
os.Exit(1)
}
}
```
You will additionally define flags and handle configuration in your init() function.
For example cmd/root.go:
```go
package cmd
import (
"fmt"
"os"
"github.com/spf13/cobra"
"github.com/spf13/viper"
)
var (
// Used for flags.
cfgFile string
userLicense string
rootCmd = &cobra.Command{
Use: "cobra",
Short: "A generator for Cobra based Applications",
Long: `Cobra is a CLI library for Go that empowers applications.
This application is a tool to generate the needed files
to quickly create a Cobra application.`,
}
)
// Execute executes the root command.
func Execute() error {
return rootCmd.Execute()
}
func init() {
cobra.OnInitialize(initConfig)
rootCmd.PersistentFlags().StringVar(&cfgFile, "config", "", "config file (default is $HOME/.cobra.yaml)")
rootCmd.PersistentFlags().StringP("author", "a", "YOUR NAME", "author name for copyright attribution")
rootCmd.PersistentFlags().StringVarP(&userLicense, "license", "l", "", "name of license for the project")
rootCmd.PersistentFlags().Bool("viper", true, "use Viper for configuration")
viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
viper.BindPFlag("useViper", rootCmd.PersistentFlags().Lookup("viper"))
viper.SetDefault("author", "NAME HERE <EMAIL ADDRESS>")
viper.SetDefault("license", "apache")
rootCmd.AddCommand(addCmd)
rootCmd.AddCommand(initCmd)
}
func initConfig() {
if cfgFile != "" {
// Use config file from the flag.
viper.SetConfigFile(cfgFile)
} else {
// Find home directory.
home, err := os.UserHomeDir()
cobra.CheckErr(err)
// Search config in home directory with name ".cobra" (without extension).
viper.AddConfigPath(home)
viper.SetConfigType("yaml")
viper.SetConfigName(".cobra")
}
viper.AutomaticEnv()
if err := viper.ReadInConfig(); err == nil {
fmt.Println("Using config file:", viper.ConfigFileUsed())
}
}
```
### Create your main.go
With the root command you need to have your main function execute it.
Execute should be run on the root for clarity, though it can be called on any command.
In a Cobra app, typically the main.go file is very bare. It serves one purpose: to initialize Cobra.
```go
package main
import (
"{pathToYourApp}/cmd"
)
func main() {
cmd.Execute()
}
```
### Create additional commands
Additional commands can be defined and typically are each given their own file
inside of the cmd/ directory.
If you wanted to create a version command you would create cmd/version.go and
populate it with the following:
```go
package cmd
import (
"fmt"
"github.com/spf13/cobra"
)
func init() {
rootCmd.AddCommand(versionCmd)
}
var versionCmd = &cobra.Command{
Use: "version",
Short: "Print the version number of Hugo",
Long: `All software has versions. This is Hugo's`,
Run: func(cmd *cobra.Command, args []string) {
fmt.Println("Hugo Static Site Generator v0.9 -- HEAD")
},
}
```
### Returning and handling errors
If you wish to return an error to the caller of a command, `RunE` can be used.
```go
package cmd
import (
"fmt"
"github.com/spf13/cobra"
)
func init() {
rootCmd.AddCommand(tryCmd)
}
var tryCmd = &cobra.Command{
Use: "try",
Short: "Try and possibly fail at something",
RunE: func(cmd *cobra.Command, args []string) error {
if err := someFunc(); err != nil {
return err
}
return nil
},
}
```
The error can then be caught at the execute function call.
## Working with Flags
Flags provide modifiers to control how the action command operates.
### Assign flags to a command
Since the flags are defined and used in different locations, we need to
define a variable outside with the correct scope to assign the flag to
work with.
```go
var Verbose bool
var Source string
```
There are two different approaches to assign a flag.
### Persistent Flags
A flag can be 'persistent', meaning that this flag will be available to the
command it's assigned to as well as every command under that command. For
global flags, assign a flag as a persistent flag on the root.
```go
rootCmd.PersistentFlags().BoolVarP(&Verbose, "verbose", "v", false, "verbose output")
```
### Local Flags
A flag can also be assigned locally, which will only apply to that specific command.
```go
localCmd.Flags().StringVarP(&Source, "source", "s", "", "Source directory to read from")
```
### Local Flag on Parent Commands
By default, Cobra only parses local flags on the target command, and any local flags on
parent commands are ignored. By enabling `Command.TraverseChildren`, Cobra will
parse local flags on each command before executing the target command.
```go
command := cobra.Command{
Use: "print [OPTIONS] [COMMANDS]",
TraverseChildren: true,
}
```
### Bind Flags with Config
You can also bind your flags with [viper](https://github.com/spf13/viper):
```go
var author string
func init() {
rootCmd.PersistentFlags().StringVar(&author, "author", "YOUR NAME", "Author name for copyright attribution")
viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
}
```
In this example, the persistent flag `author` is bound with `viper`.
**Note**: the variable `author` will not be set to the value from config,
when the `--author` flag is provided by user.
More in [viper documentation](https://github.com/spf13/viper#working-with-flags).
### Required flags
Flags are optional by default. If instead you wish your command to report an error
when a flag has not been set, mark it as required:
```go
rootCmd.Flags().StringVarP(&Region, "region", "r", "", "AWS region (required)")
rootCmd.MarkFlagRequired("region")
```
Or, for persistent flags:
```go
rootCmd.PersistentFlags().StringVarP(&Region, "region", "r", "", "AWS region (required)")
rootCmd.MarkPersistentFlagRequired("region")
```
## Positional and Custom Arguments
Validation of positional arguments can be specified using the `Args` field
of `Command`.
The following validators are built in:
- `NoArgs` - the command will report an error if there are any positional args.
- `ArbitraryArgs` - the command will accept any args.
- `OnlyValidArgs` - the command will report an error if there are any positional args that are not in the `ValidArgs` field of `Command`.
- `MinimumNArgs(int)` - the command will report an error if there are not at least N positional args.
- `MaximumNArgs(int)` - the command will report an error if there are more than N positional args.
- `ExactArgs(int)` - the command will report an error if there are not exactly N positional args.
- `ExactValidArgs(int)` - the command will report an error if there are not exactly N positional args OR if there are any positional args that are not in the `ValidArgs` field of `Command`
- `RangeArgs(min, max)` - the command will report an error if the number of args is not between the minimum and maximum number of expected args.
- `MatchAll(pargs ...PositionalArgs)` - enables combining existing checks with arbitrary other checks (e.g. you want to check the ExactArgs length along with other qualities).
An example of setting the custom validator:
```go
var cmd = &cobra.Command{
Short: "hello",
Args: func(cmd *cobra.Command, args []string) error {
if len(args) < 1 {
return errors.New("requires a color argument")
}
if myapp.IsValidColor(args[0]) {
return nil
}
return fmt.Errorf("invalid color specified: %s", args[0])
},
Run: func(cmd *cobra.Command, args []string) {
fmt.Println("Hello, World!")
},
}
```
## Example
In the example below, we have defined three commands. Two are at the top level
and one (cmdTimes) is a child of one of the top commands. In this case the root
is not executable, meaning that a subcommand is required. This is accomplished
by not providing a 'Run' for the 'rootCmd'.
We have only defined one flag for a single command.
More documentation about flags is available at https://github.com/spf13/pflag
```go
package main
import (
"fmt"
"strings"
"github.com/spf13/cobra"
)
func main() {
var echoTimes int
var cmdPrint = &cobra.Command{
Use: "print [string to print]",
Short: "Print anything to the screen",
Long: `print is for printing anything back to the screen.
For many years people have printed back to the screen.`,
Args: cobra.MinimumNArgs(1),
Run: func(cmd *cobra.Command, args []string) {
fmt.Println("Print: " + strings.Join(args, " "))
},
}
var cmdEcho = &cobra.Command{
Use: "echo [string to echo]",
Short: "Echo anything to the screen",
Long: `echo is for echoing anything back.
Echo works a lot like print, except it has a child command.`,
Args: cobra.MinimumNArgs(1),
Run: func(cmd *cobra.Command, args []string) {
fmt.Println("Echo: " + strings.Join(args, " "))
},
}
var cmdTimes = &cobra.Command{
Use: "times [string to echo]",
Short: "Echo anything to the screen more times",
Long: `echo things multiple times back to the user by providing
a count and a string.`,
Args: cobra.MinimumNArgs(1),
Run: func(cmd *cobra.Command, args []string) {
for i := 0; i < echoTimes; i++ {
fmt.Println("Echo: " + strings.Join(args, " "))
}
},
}
cmdTimes.Flags().IntVarP(&echoTimes, "times", "t", 1, "times to echo the input")
var rootCmd = &cobra.Command{Use: "app"}
rootCmd.AddCommand(cmdPrint, cmdEcho)
cmdEcho.AddCommand(cmdTimes)
rootCmd.Execute()
}
```
For a more complete example of a larger application, please checkout [Hugo](http://gohugo.io/).
## Help Command
Cobra automatically adds a help command to your application when you have subcommands.
This will be called when a user runs 'app help'. Additionally, help will also
support all other commands as input. Say, for instance, you have a command called
'create' without any additional configuration; Cobra will work when 'app help
create' is called. Every command will automatically have the '--help' flag added.
### Example
The following output is automatically generated by Cobra. Nothing beyond the
command and flag definitions are needed.
$ cobra help
Cobra is a CLI library for Go that empowers applications.
This application is a tool to generate the needed files
to quickly create a Cobra application.
Usage:
cobra [command]
Available Commands:
add Add a command to a Cobra Application
help Help about any command
init Initialize a Cobra Application
Flags:
-a, --author string author name for copyright attribution (default "YOUR NAME")
--config string config file (default is $HOME/.cobra.yaml)
-h, --help help for cobra
-l, --license string name of license for the project
--viper use Viper for configuration (default true)
Use "cobra [command] --help" for more information about a command.
Help is just a command like any other. There is no special logic or behavior
around it. In fact, you can provide your own if you want.
### Defining your own help
You can provide your own Help command or your own template for the default command to use
with following functions:
```go
cmd.SetHelpCommand(cmd *Command)
cmd.SetHelpFunc(f func(*Command, []string))
cmd.SetHelpTemplate(s string)
```
The latter two will also apply to any children commands.
## Usage Message
When the user provides an invalid flag or invalid command, Cobra responds by
showing the user the 'usage'.
### Example
You may recognize this from the help above. That's because the default help
embeds the usage as part of its output.
$ cobra --invalid
Error: unknown flag: --invalid
Usage:
cobra [command]
Available Commands:
add Add a command to a Cobra Application
help Help about any command
init Initialize a Cobra Application
Flags:
-a, --author string author name for copyright attribution (default "YOUR NAME")
--config string config file (default is $HOME/.cobra.yaml)
-h, --help help for cobra
-l, --license string name of license for the project
--viper use Viper for configuration (default true)
Use "cobra [command] --help" for more information about a command.
### Defining your own usage
You can provide your own usage function or template for Cobra to use.
Like help, the function and template are overridable through public methods:
```go
cmd.SetUsageFunc(f func(*Command) error)
cmd.SetUsageTemplate(s string)
```
## Version Flag
Cobra adds a top-level '--version' flag if the Version field is set on the root command.
Running an application with the '--version' flag will print the version to stdout using
the version template. The template can be customized using the
`cmd.SetVersionTemplate(s string)` function.
## PreRun and PostRun Hooks
It is possible to run functions before or after the main `Run` function of your command. The `PersistentPreRun` and `PreRun` functions will be executed before `Run`. `PersistentPostRun` and `PostRun` will be executed after `Run`. The `Persistent*Run` functions will be inherited by children if they do not declare their own. These functions are run in the following order:
- `PersistentPreRun`
- `PreRun`
- `Run`
- `PostRun`
- `PersistentPostRun`
An example of two commands which use all of these features is below. When the subcommand is executed, it will run the root command's `PersistentPreRun` but not the root command's `PersistentPostRun`:
```go
package main
import (
"fmt"
"github.com/spf13/cobra"
)
func main() {
var rootCmd = &cobra.Command{
Use: "root [sub]",
Short: "My root command",
PersistentPreRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside rootCmd PersistentPreRun with args: %v\n", args)
},
PreRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside rootCmd PreRun with args: %v\n", args)
},
Run: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside rootCmd Run with args: %v\n", args)
},
PostRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside rootCmd PostRun with args: %v\n", args)
},
PersistentPostRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside rootCmd PersistentPostRun with args: %v\n", args)
},
}
var subCmd = &cobra.Command{
Use: "sub [no options!]",
Short: "My subcommand",
PreRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside subCmd PreRun with args: %v\n", args)
},
Run: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside subCmd Run with args: %v\n", args)
},
PostRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside subCmd PostRun with args: %v\n", args)
},
PersistentPostRun: func(cmd *cobra.Command, args []string) {
fmt.Printf("Inside subCmd PersistentPostRun with args: %v\n", args)
},
}
rootCmd.AddCommand(subCmd)
rootCmd.SetArgs([]string{""})
rootCmd.Execute()
fmt.Println()
rootCmd.SetArgs([]string{"sub", "arg1", "arg2"})
rootCmd.Execute()
}
```
Output:
```
Inside rootCmd PersistentPreRun with args: []
Inside rootCmd PreRun with args: []
Inside rootCmd Run with args: []
Inside rootCmd PostRun with args: []
Inside rootCmd PersistentPostRun with args: []
Inside rootCmd PersistentPreRun with args: [arg1 arg2]
Inside subCmd PreRun with args: [arg1 arg2]
Inside subCmd Run with args: [arg1 arg2]
Inside subCmd PostRun with args: [arg1 arg2]
Inside subCmd PersistentPostRun with args: [arg1 arg2]
```
## Suggestions when "unknown command" happens
Cobra will print automatic suggestions when "unknown command" errors happen. This allows Cobra to behave similarly to the `git` command when a typo happens. For example:
```
$ hugo srever
Error: unknown command "srever" for "hugo"
Did you mean this?
server
Run 'hugo --help' for usage.
```
Suggestions are automatic based on every subcommand registered and use an implementation of [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance). Every registered command that matches a minimum distance of 2 (ignoring case) will be displayed as a suggestion.
If you need to disable suggestions or tweak the string distance in your command, use:
```go
command.DisableSuggestions = true
```
or
```go
command.SuggestionsMinimumDistance = 1
```
You can also explicitly set names for which a given command will be suggested using the `SuggestFor` attribute. This allows suggestions for strings that are not close in terms of string distance, but makes sense in your set of commands and for some which you don't want aliases. Example:
```
$ kubectl remove
Error: unknown command "remove" for "kubectl"
Did you mean this?
delete
Run 'kubectl help' for usage.
```
## Generating documentation for your command
Cobra can generate documentation based on subcommands, flags, etc. Read more about it in the [docs generation documentation](doc/README.md).
## Generating shell completions
Cobra can generate a shell-completion file for the following shells: bash, zsh, fish, PowerShell. If you add more information to your commands, these completions can be amazingly powerful and flexible. Read more about it in [Shell Completions](shell_completions.md).

# Generating Bash Completions For Your cobra.Command
Please refer to [Shell Completions](shell_completions.md) for details.
## Bash legacy dynamic completions
For backward compatibility, Cobra still supports its legacy dynamic completion solution (described below). Unlike the `ValidArgsFunction` solution, the legacy solution will only work for Bash shell-completion and not for other shells. This legacy solution can be used along-side `ValidArgsFunction` and `RegisterFlagCompletionFunc()`, as long as both solutions are not used for the same command. This provides a path to gradually migrate from the legacy solution to the new solution.
**Note**: Cobra's default `completion` command uses bash completion V2. If you are currently using Cobra's legacy dynamic completion solution, you should not use the default `completion` command but continue using your own.
The legacy solution allows you to inject bash functions into the bash completion script. Those bash functions are responsible for providing the completion choices for your own completions.
Some code that works in kubernetes:
```bash
const (
bash_completion_func = `__kubectl_parse_get()
{
local kubectl_output out
if kubectl_output=$(kubectl get --no-headers "$1" 2>/dev/null); then
out=($(echo "${kubectl_output}" | awk '{print $1}'))
COMPREPLY=( $( compgen -W "${out[*]}" -- "$cur" ) )
fi
}
__kubectl_get_resource()
{
if [[ ${#nouns[@]} -eq 0 ]]; then
return 1
fi
__kubectl_parse_get ${nouns[${#nouns[@]} -1]}
if [[ $? -eq 0 ]]; then
return 0
fi
}
__kubectl_custom_func() {
case ${last_command} in
kubectl_get | kubectl_describe | kubectl_delete | kubectl_stop)
__kubectl_get_resource
return
;;
*)
;;
esac
}
`)
```
And then I set that in my command definition:
```go
cmds := &cobra.Command{
Use: "kubectl",
Short: "kubectl controls the Kubernetes cluster manager",
Long: `kubectl controls the Kubernetes cluster manager.
Find more information at https://github.com/GoogleCloudPlatform/kubernetes.`,
Run: runHelp,
BashCompletionFunction: bash_completion_func,
}
```
The `BashCompletionFunction` option is really only valid/useful on the root command. Doing the above will cause `__kubectl_custom_func()` (`__<command-use>_custom_func()`) to be called when the built in processor was unable to find a solution. In the case of kubernetes a valid command might look something like `kubectl get pod [mypod]`. If you type `kubectl get pod [tab][tab]` the `__kubectl_customc_func()` will run because the cobra.Command only understood "kubectl" and "get." `__kubectl_custom_func()` will see that the cobra.Command is "kubectl_get" and will thus call another helper `__kubectl_get_resource()`. `__kubectl_get_resource` will look at the 'nouns' collected. In our example the only noun will be `pod`. So it will call `__kubectl_parse_get pod`. `__kubectl_parse_get` will actually call out to kubernetes and get any pods. It will then set `COMPREPLY` to valid pods!
Similarly, for flags:
```go
annotation := make(map[string][]string)
annotation[cobra.BashCompCustom] = []string{"__kubectl_get_namespaces"}
flag := &pflag.Flag{
Name: "namespace",
Usage: usage,
Annotations: annotation,
}
cmd.Flags().AddFlag(flag)
```
In addition add the `__kubectl_get_namespaces` implementation in the `BashCompletionFunction`
value, e.g.:
```bash
__kubectl_get_namespaces()
{
local template
template="{{ range .items }}{{ .metadata.name }} {{ end }}"
local kubectl_out
if kubectl_out=$(kubectl get -o template --template="${template}" namespace 2>/dev/null); then
COMPREPLY=( $( compgen -W "${kubectl_out}[*]" -- "$cur" ) )
fi
}
```

## Cobra User Contract
### Versioning
Cobra will follow a steady release cadence. Non breaking changes will be released as minor versions quarterly. Patch bug releases are at the discretion of the maintainers. Users can expect security patch fixes to be released within relatively short order of a CVE becoming known. For more information on security patch fixes see the CVE section below. Releases will follow [Semantic Versioning](https://semver.org/). Users tracking the Master branch should expect unpredictable breaking changes as the project continues to move forward. For stability, it is highly recommended to use a release.
### Backward Compatibility
We will maintain two major releases in a moving window. The N-1 release will only receive bug fixes and security updates and will be dropped once N+1 is released.
### Deprecation
Deprecation of Go versions or dependent packages will only occur in major releases. To reduce the change of this taking users by surprise, any large deprecation will be preceded by an announcement in the [#cobra slack channel](https://gophers.slack.com/archives/CD3LP1199) and an Issue on Github.
### CVE
Maintainers will make every effort to release security patches in the case of a medium to high severity CVE directly impacting the library. The speed in which these patches reach a release is up to the discretion of the maintainers. A low severity CVE may be a lower priority than a high severity one.
### Communication
Cobra maintainers will use GitHub issues and the [#cobra slack channel](https://gophers.slack.com/archives/CD3LP1199) as the primary means of communication with the community. This is to foster open communication with all users and contributors.
### Breaking Changes
Breaking changes are generally allowed in the master branch, as this is the branch used to develop the next release of Cobra.
There may be times, however, when master is closed for breaking changes. This is likely to happen as we near the release of a new version.
Breaking changes are not allowed in release branches, as these represent minor versions that have already been released. These version have consumers who expect the APIs, behaviors, etc, to remain stable during the lifetime of the patch stream for the minor release.
Examples of breaking changes include:
- Removing or renaming exported constant, variable, type, or function.
- Updating the version of critical libraries such as `spf13/pflag`, `spf13/viper` etc...
- Some version updates may be acceptable for picking up bug fixes, but maintainers must exercise caution when reviewing.
There may, at times, need to be exceptions where breaking changes are allowed in release branches. These are at the discretion of the project's maintainers, and must be carefully considered before merging.
### CI Testing
Maintainers will ensure the Cobra test suite utilizes the current supported versions of Golang.
### Disclaimer
Changes to this document and the contents therein are at the discretion of the maintainers.
None of the contents of this document are legally binding in any way to the maintainers or the users.

Load environment variables dynamically in Go.
## Usage
Put the gotenv package on your `import` statement:
```go
import "github.com/subosito/gotenv"
```
To modify your app environment variables, `gotenv` expose 2 main functions:
- `gotenv.Load`
- `gotenv.Apply`
By default, `gotenv.Load` will look for a file called `.env` in the current working directory.
Behind the scene, it will then load `.env` file and export the valid variables to the environment variables. Make sure you call the method as soon as possible to ensure it loads all variables, say, put it on `init()` function.
Once loaded you can use `os.Getenv()` to get the value of the variable.
Let's say you have `.env` file:
```
APP_ID=1234567
APP_SECRET=abcdef
```
Here's the example of your app:
```go
package main
import (
"github.com/subosito/gotenv"
"log"
"os"
)
func init() {
gotenv.Load()
}
func main() {
log.Println(os.Getenv("APP_ID")) // "1234567"
log.Println(os.Getenv("APP_SECRET")) // "abcdef"
}
```
You can also load other than `.env` file if you wish. Just supply filenames when calling `Load()`. It will load them in order and the first value set for a variable will win.:
```go
gotenv.Load(".env.production", "credentials")
```
While `gotenv.Load` loads entries from `.env` file, `gotenv.Apply` allows you to use any `io.Reader`:
```go
gotenv.Apply(strings.NewReader("APP_ID=1234567"))
log.Println(os.Getenv("APP_ID"))
// Output: "1234567"
```
Both `gotenv.Load` and `gotenv.Apply` **DO NOT** overrides existing environment variables. If you want to override existing ones, you can see section below.
### Environment Overrides
Besides above functions, `gotenv` also provides another functions that overrides existing:
- `gotenv.OverLoad`
- `gotenv.OverApply`
Here's the example of this overrides behavior:
```go
os.Setenv("HELLO", "world")
// NOTE: using Apply existing value will be reserved
gotenv.Apply(strings.NewReader("HELLO=universe"))
fmt.Println(os.Getenv("HELLO"))
// Output: "world"
// NOTE: using OverApply existing value will be overridden
gotenv.OverApply(strings.NewReader("HELLO=universe"))
fmt.Println(os.Getenv("HELLO"))
// Output: "universe"
```
### Throw a Panic
Both `gotenv.Load` and `gotenv.OverLoad` returns an error on something wrong occurred, like your env file is not exist, and so on. To make it easier to use, `gotenv` also provides `gotenv.Must` helper, to let it panic when an error returned.
```go
err := gotenv.Load(".env-is-not-exist")
fmt.Println("error", err)
// error: open .env-is-not-exist: no such file or directory
gotenv.Must(gotenv.Load, ".env-is-not-exist")
// it will throw a panic
// panic: open .env-is-not-exist: no such file or directory
```
### Another Scenario
Just in case you want to parse environment variables from any `io.Reader`, gotenv keeps its `Parse` and `StrictParse` function as public API so you can use that.
```go
// import "strings"
pairs := gotenv.Parse(strings.NewReader("FOO=test\nBAR=$FOO"))
// gotenv.Env{"FOO": "test", "BAR": "test"}
err, pairs = gotenv.StrictParse(strings.NewReader(`FOO="bar"`))
// gotenv.Env{"FOO": "bar"}
```
`Parse` ignores invalid lines and returns `Env` of valid environment variables, while `StrictParse` returns an error for invalid lines.
## Notes
The gotenv package is a Go port of [`dotenv`](https://github.com/bkeepers/dotenv) project with some additions made for Go. For general features, it aims to be compatible as close as possible.

// Package require implements the same assertions as the `assert` package but
// stops test execution when a test fails.
//
// Example Usage
//
// The following is a complete example using require in a standard test function:
// import (
// "testing"
// "github.com/stretchr/testify/require"
// )
//
// func TestSomething(t *testing.T) {
//
// var a string = "Hello"
// var b string = "Hello"
//
// require.Equal(t, a, b, "The two words should be the same.")
//
// }
//
// Assertions
//
// The `require` package have same global functions as in the `assert` package,
// but instead of returning a boolean result they call `t.FailNow()`.
//
// Every assertion function also takes an optional string message as the final argument,
// allowing custom error messages to be appended to the message the assertion method outputs.

// Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.
//
// Example Usage
//
// The following is a complete example using assert in a standard test function:
// import (
// "testing"
// "github.com/stretchr/testify/assert"
// )
//
// func TestSomething(t *testing.T) {
//
// var a string = "Hello"
// var b string = "Hello"
//
// assert.Equal(t, a, b, "The two words should be the same.")
//
// }
//
// if you assert many times, use the format below:
//
// import (
// "testing"
// "github.com/stretchr/testify/assert"
// )
//
// func TestSomething(t *testing.T) {
// assert := assert.New(t)
//
// var a string = "Hello"
// var b string = "Hello"
//
// assert.Equal(a, b, "The two words should be the same.")
// }
//
// Assertions
//
// Assertions allow you to easily write test code, and are global funcs in the `assert` package.
// All assertion functions take, as the first argument, the `*testing.T` object provided by the
// testing framework. This allows the assertion funcs to write the failings and other details to
// the correct place.
//
// Every assertion function also takes an optional string message as the final argument,
// allowing custom error messages to be appended to the message the assertion method outputs.

# oauth
A library for Go client applications that need to perform OAuth authorization against a server, typically GitHub.com.
<p align="center">
<img width="598" alt="" src="https://user-images.githubusercontent.com/887/102650961-f2751e80-416b-11eb-8b37-d82b076eb2d1.png"><br>
<img width="976" alt="" src="https://user-images.githubusercontent.com/887/102650543-5e0abc00-416b-11eb-8e54-7b6e334ab092.png">
</p>
Traditionally, OAuth for web applications involves redirecting to a URI after the user authorizes an app. While web apps (and some native client apps) can receive a browser redirect, client apps such as CLI applications do not have such an option.
To accommodate client apps, this library implements the [OAuth Device Authorization Grant][oauth-device] which [GitHub.com now supports][gh-device]. With Device flow, the user is presented with a one-time code that they will have to enter in a web browser while authorizing the app on the server. Device flow is suitable for cases where the web browser may be running on a separate device than the client app itself; for example a CLI application could run within a headless, containerized instance, but the user may complete authorization using a browser on their phone.
To transparently enable OAuth authorization on _any GitHub host_ (e.g. GHES instances without OAuth “Device flow” support), this library also bundles an implementation of OAuth web application flow in which the client app starts a local server at `http://127.0.0.1:<port>/` that acts as a receiver for the browser redirect. First, Device flow is attempted, and the localhost server is used as fallback. With the localhost server, the user's web browser must be running on the same machine as the client application itself.
## Usage
- [OAuth Device flow with fallback](./examples_test.go)
- [manual OAuth Device flow](./device/examples_test.go)
- [manual OAuth web application flow](./webapp/examples_test.go)
Applications that need more control over the user experience around authentication should directly interface with `github.com/cli/oauth/device` and `github.com/cli/oauth/webapp` packages.
In theory, these packages would enable authorization on any OAuth-enabled host. In practice, however, this was only tested for authorizing with GitHub.

# go-homedir
This is a Go library for detecting the user's home directory without
the use of cgo, so the library can be used in cross-compilation environments.
Usage is incredibly simple, just call `homedir.Dir()` to get the home directory
for a user, and `homedir.Expand()` to expand the `~` in a path to the home
directory.
**Why not just use `os/user`?** The built-in `os/user` package requires
cgo on Darwin systems. This means that any Go code that uses that package
cannot cross compile. But 99% of the time the use for `os/user` is just to
retrieve the home directory, which we can do for the current user without
cgo. This library does that, enabling cross-compilation.

// Package mapstructure exposes functionality to convert one arbitrary
// Go type into another, typically to convert a map[string]interface{}
// into a native Go structure.
//
// The Go structure can be arbitrarily complex, containing slices,
// other structs, etc. and the decoder will properly decode nested
// maps and so on into the proper structures in the native Go struct.
// See the examples to see what the decoder is capable of.
//
// The simplest function to start with is Decode.
//
// Field Tags
//
// When decoding to a struct, mapstructure will use the field name by
// default to perform the mapping. For example, if a struct has a field
// "Username" then mapstructure will look for a key in the source value
// of "username" (case insensitive).
//
// type User struct {
// Username string
// }
//
// You can change the behavior of mapstructure by using struct tags.
// The default struct tag that mapstructure looks for is "mapstructure"
// but you can customize it using DecoderConfig.
//
// Renaming Fields
//
// To rename the key that mapstructure looks for, use the "mapstructure"
// tag and set a value directly. For example, to change the "username" example
// above to "user":
//
// type User struct {
// Username string `mapstructure:"user"`
// }
//
// Embedded Structs and Squashing
//
// Embedded structs are treated as if they're another field with that name.
// By default, the two structs below are equivalent when decoding with
// mapstructure:
//
// type Person struct {
// Name string
// }
//
// type Friend struct {
// Person
// }
//
// type Friend struct {
// Person Person
// }
//
// This would require an input that looks like below:
//
// map[string]interface{}{
// "person": map[string]interface{}{"name": "alice"},
// }
//
// If your "person" value is NOT nested, then you can append ",squash" to
// your tag value and mapstructure will treat it as if the embedded struct
// were part of the struct directly. Example:
//
// type Friend struct {
// Person `mapstructure:",squash"`
// }
//
// Now the following input would be accepted:
//
// map[string]interface{}{
// "name": "alice",
// }
//
// When decoding from a struct to a map, the squash tag squashes the struct
// fields into a single map. Using the example structs from above:
//
// Friend{Person: Person{Name: "alice"}}
//
// Will be decoded into a map:
//
// map[string]interface{}{
// "name": "alice",
// }
//
// DecoderConfig has a field that changes the behavior of mapstructure
// to always squash embedded structs.
//
// Remainder Values
//
// If there are any unmapped keys in the source value, mapstructure by
// default will silently ignore them. You can error by setting ErrorUnused
// in DecoderConfig. If you're using Metadata you can also maintain a slice
// of the unused keys.
//
// You can also use the ",remain" suffix on your tag to collect all unused
// values in a map. The field with this tag MUST be a map type and should
// probably be a "map[string]interface{}" or "map[interface{}]interface{}".
// See example below:
//
// type Friend struct {
// Name string
// Other map[string]interface{} `mapstructure:",remain"`
// }
//
// Given the input below, Other would be populated with the other
// values that weren't used (everything but "name"):
//
// map[string]interface{}{
// "name": "bob",
// "address": "123 Maple St.",
// }
//
// Omit Empty Values
//
// When decoding from a struct to any other value, you may use the
// ",omitempty" suffix on your tag to omit that value if it equates to
// the zero value. The zero value of all types is specified in the Go
// specification.
//
// For example, the zero type of a numeric type is zero ("0"). If the struct
// field value is zero and a numeric type, the field is empty, and it won't
// be encoded into the destination type.
//
// type Source {
// Age int `mapstructure:",omitempty"`
// }
//
// Unexported fields
//
// Since unexported (private) struct fields cannot be set outside the package
// where they are defined, the decoder will simply skip them.
//
// For this output type definition:
//
// type Exported struct {
// private string // this unexported field will be skipped
// Public string
// }
//
// Using this map as input:
//
// map[string]interface{}{
// "private": "I will be ignored",
// "Public": "I made it through!",
// }
//
// The following struct will be decoded:
//
// type Exported struct {
// private: "" // field is left with an empty string (zero value)
// Public: "I made it through!"
// }
//
// Other Configuration
//
// mapstructure is highly configurable. See the DecoderConfig struct
// for other features and options that are supported.

# mapstructure [](https://godoc.org/github.com/mitchellh/mapstructure)
mapstructure is a Go library for decoding generic map values to structures
and vice versa, while providing helpful error handling.
This library is most useful when decoding values from some data stream (JSON,
Gob, etc.) where you don't _quite_ know the structure of the underlying data
until you read a part of it. You can therefore read a `map[string]interface{}`
and use this library to decode it into the proper underlying native Go
structure.
## Installation
Standard `go get`:
```
$ go get github.com/mitchellh/mapstructure
```
## Usage & Example
For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/mapstructure).
The `Decode` function has examples associated with it there.
## But Why?!
Go offers fantastic standard libraries for decoding formats such as JSON.
The standard method is to have a struct pre-created, and populate that struct
from the bytes of the encoded format. This is great, but the problem is if
you have configuration or an encoding that changes slightly depending on
specific fields. For example, consider this JSON:
```json
{
"type": "person",
"name": "Mitchell"
}
```
Perhaps we can't populate a specific structure without first reading
the "type" field from the JSON. We could always do two passes over the
decoding of the JSON (reading the "type" first, and the rest later).
However, it is much simpler to just decode this into a `map[string]interface{}`
structure, read the "type" key, then use something like this library
to decode it into the proper structure.

* Squash is now supported with embedded fields that are struct pointers [GH-205]
* Empty strings will convert to 0 for all numeric types when weakly decoding [GH-206]
## 1.3.3
* Decoding maps from maps creates a settable value for decode hooks [GH-203]
## 1.3.2
* Decode into interface type with a struct value is supported [GH-187]
## 1.3.1
* Squash should only squash embedded structs. [GH-194]
## 1.3.0
* Added `",omitempty"` support. This will ignore zero values in the source
structure when encoding. [GH-145]
## 1.2.3
* Fix duplicate entries in Keys list with pointer values. [GH-185]
## 1.2.2
* Do not add unsettable (unexported) values to the unused metadata key
or "remain" value. [GH-150]
## 1.2.1
* Go modules checksum mismatch fix
## 1.2.0
* Added support to capture unused values in a field using the `",remain"` value
in the mapstructure tag. There is an example to showcase usage.
* Added `DecoderConfig` option to always squash embedded structs
* `json.Number` can decode into `uint` types
* Empty slices are preserved and not replaced with nil slices
* Fix panic that can occur in when decoding a map into a nil slice of structs
* Improved package documentation for godoc
## 1.1.2
* Fix error when decode hook decodes interface implementation into interface
type. [GH-140]
## 1.1.1
* Fix panic that can happen in `decodePtr`
## 1.1.0
* Added `StringToIPHookFunc` to convert `string` to `net.IP` and `net.IPNet` [GH-133]
* Support struct to struct decoding [GH-137]
* If source map value is nil, then destination map value is nil (instead of empty)
* If source slice value is nil, then destination slice value is nil (instead of empty)
* If source pointer is nil, then destination pointer is set to nil (instead of
allocated zero value of type)
## 1.0.0
* Initial tagged stable release.

# File system notifications for Go
[](https://godoc.org/github.com/fsnotify/fsnotify) [](https://goreportcard.com/report/github.com/fsnotify/fsnotify)
fsnotify utilizes [golang.org/x/sys](https://godoc.org/golang.org/x/sys) rather than `syscall` from the standard library. Ensure you have the latest version installed by running:
```console
go get -u golang.org/x/sys/...
```
Cross platform: Windows, Linux, BSD and macOS.
| Adapter | OS | Status |
| --------------------- | -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------- |
| inotify | Linux 2.6.27 or later, Android\* | Supported |
| kqueue | BSD, macOS, iOS\* | Supported |
| ReadDirectoryChangesW | Windows | Supported |
| FSEvents | macOS | [Planned](https://github.com/fsnotify/fsnotify/issues/11) |
| FEN | Solaris 11 | [In Progress](https://github.com/fsnotify/fsnotify/issues/12) |
| fanotify | Linux 2.6.37+ | [Planned](https://github.com/fsnotify/fsnotify/issues/114) |
| USN Journals | Windows | [Maybe](https://github.com/fsnotify/fsnotify/issues/53) |
| Polling | *All* | [Maybe](https://github.com/fsnotify/fsnotify/issues/9) |
\* Android and iOS are untested.
Please see [the documentation](https://godoc.org/github.com/fsnotify/fsnotify) and consult the [FAQ](#faq) for usage information.
## API stability
fsnotify is a fork of [howeyc/fsnotify](https://godoc.org/github.com/howeyc/fsnotify) with a new API as of v1.0. The API is based on [this design document](http://goo.gl/MrYxyA).
All [releases](https://github.com/fsnotify/fsnotify/releases) are tagged based on [Semantic Versioning](http://semver.org/). Further API changes are [planned](https://github.com/fsnotify/fsnotify/milestones), and will be tagged with a new major revision number.
Go 1.6 supports dependencies located in the `vendor/` folder. Unless you are creating a library, it is recommended that you copy fsnotify into `vendor/github.com/fsnotify/fsnotify` within your project, and likewise for `golang.org/x/sys`.
## Usage
```go
package main
import (
"log"
"github.com/fsnotify/fsnotify"
)
func main() {
watcher, err := fsnotify.NewWatcher()
if err != nil {
log.Fatal(err)
}
defer watcher.Close()
done := make(chan bool)
go func() {
for {
select {
case event, ok := <-watcher.Events:
if !ok {
return
}
log.Println("event:", event)
if event.Op&fsnotify.Write == fsnotify.Write {
log.Println("modified file:", event.Name)
}
case err, ok := <-watcher.Errors:
if !ok {
return
}
log.Println("error:", err)
}
}
}()
err = watcher.Add("/tmp/foo")
if err != nil {
log.Fatal(err)
}
<-done
}
```

## FAQ
**When a file is moved to another directory is it still being watched?**
No (it shouldn't be, unless you are watching where it was moved to).
**When I watch a directory, are all subdirectories watched as well?**
No, you must add watches for any directory you want to watch (a recursive watcher is on the roadmap [#18][]).
**Do I have to watch the Error and Event channels in a separate goroutine?**
As of now, yes. Looking into making this single-thread friendly (see [howeyc #7][#7])
**Why am I receiving multiple events for the same file on OS X?**
Spotlight indexing on OS X can result in multiple events (see [howeyc #62][#62]). A temporary workaround is to add your folder(s) to the *Spotlight Privacy settings* until we have a native FSEvents implementation (see [#11][]).
**How many files can be watched at once?**
There are OS-specific limits as to how many watches can be created:
* Linux: /proc/sys/fs/inotify/max_user_watches contains the limit, reaching this limit results in a "no space left on device" error.
* BSD / OSX: sysctl variables "kern.maxfiles" and "kern.maxfilesperproc", reaching these limits results in a "too many open files" error.
**Why don't notifications work with NFS filesystems or filesystem in userspace (FUSE)?**
fsnotify requires support from underlying OS to work. The current NFS protocol does not provide network level support for file notifications.
