d7402 | train | Here are a few methods on how to center an HTML element:
*
*The oldest trick in the book:
.form {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%)
}
This works by moving the form element 50% to the left and 50% to the top of the container and move's it back 50% of its width and height.
*flex
.form-container {
display: flex;
align-items: center;
justify-content: center;
}
Set the container of the form to flex and align it to the center vertically and horizontally.
*grid
.form-container {
display: grid;
place-items: center;
}
Same thing as flex, but both justify-content and align-items are merged into the same line.
You can give the same CSS to your form using tailwindcss:
1.
<form class="absolute top-1/2 left-1/2 translate-x-1/2 translate-y-1/2">
*
<div class="bg-gray-600 flex items-center justify-center">
*
<div class="bg-gray-600 grid place-items-center">
Hope this helps!
A: Apply this css on the parent of your form, in this case, probably the bg-gray-600
.bg-gray-600 {
display:flex;
justify-content:center; /*horizontal center*/
align-items:center; /*vertical center*/
}
You might need to define width or height of the parent in order this to work. Depends on your CSS.
The * that you said you dont understand is used to select every element within the whole page, so the bg-gray-600 as well. In this case, none of its values effect the centering of your form. | unknown | |
d7403 | train | Let's build this gradually, and start with a simple substitution that prepends a newline (\r) to any sequence of comment prefixes (!):
:%substitute/!\+.*$/\r&/
This leaves behind trailing whitespace. We can match that as well, and use a capture group (\(...\)) for the actual comment. This removes the whitespace:
:%substitute/\s*\(!\+.*$\)/\r\1/
But it still matches comments at the start of a line, and introduces an additional empty line in front. We can add a lookbehind assertion that the line must not start with a !, but this now gets ugly:
:%substitute/^\%(^[^!].*\)\@=.*\zs\s*\(!\+.*$\)/\r\1/
Instead, it's easier to use another Vim command, :global (or its inverted sister :vglobal), to only match lines not starting with !, and then apply the :substitute there:
:%vglobal/^!/substitute/\s*\(!\+.*$\)/\r\1/
The final requirement is that exclamation marks within strings should be kept. This would add another regular expression, and integrating it into the overall match would be really hard, and could probably be only done approximately. Fortunately, with syntax highlighting, Vim already knows what is a Fortran string!
My PatternsOnText plugin has (among others) a :SubstituteIf / :SubstituteUnless combo that can do substitutions only if a condition is true / false. The library it depends on provides a wrapper around synIdAttr() that makes it easy to define a predicate for Fortran strings:
function! IsFortranString()
return ingo#syntaxitem#IsOnSyntax(getpos('.'), '^fortranString')
endfunction
We then only need to replace :substitute with :SubstituteUnless + predicate:
:%vglobal/^!/SubstituteUnless/\s*\(!\+.*$\)/\r\1/ IsFortranString()
The same can also be achieved without the plugin (using :help sub-replace-special and synstack() / synIdAttr()), but it'd be more complex. | unknown | |
d7404 | train | to remove lines which starts with alphabets after IP word and also
delete that line which do not starts with 192.168.180 after IP word
awk approach:
awk '$4!~/^[[:alpha:]]/ && $4~/^192\.168\.180/' file
space is a default field separator in awk.
$4!~/^[[:alpha:]]/:
$4 - fourth field
!~ - not matches
/^[[:alpha:]]/ - regular expression, means "starts with alphabetic characters"
&& - boolean "and" operator.
boolean1 && boolean2 - True if both boolean1 and boolean2 are true.
$4~/^192\.168\.180/ - matches a line if the fourth field starts with 192.168.180
Additional approach:
To strip the unneeded parts of certain columns use the following approach:
awk -v p=".[^.]+$" '$4!~/^[[:alpha:]]/ && $4~/^192\.168\.180/
{$7=$8="";for(i=2;i<=6;i+=2)gsub(p,"",$i);print}' file

d7405 | train | Unfortunately, I don't have enough karma to comment, so I'll do the best I can to provide a solution here.
Have you made sure to run 'rails generate devise:install' before attempting to generate the devise model? Also make sure that you ran 'bundle install' before you attempt either of installing Devise or generating a model.
A: hope u followed these steps:-
*
*Add gem 'devise' to gemfile
*Run the bundle command to install it.
*After you install Devise and add it to your Gemfile, you need to run the generator:
rails generate devise:install
The generator will install an initializer which describes ALL Devise's configuration options and you MUST take a look at it.
4. When you are done, you are ready to add Devise to any of your models using the generator:

d7406 | train | Instead of using SelectedRows property of the DataGridview you can use as follows
dataGridView1.Rows[1].DefaultCellStyle.ForeColor = Color.Red;
Because SelectedRows property will return rows when row(s) has been selected by the User only, if no rows are selected then your code will throw exception.
EDIT :
For your doubt here am providing a sample code, hope it will help you.
for (int i = 0; i < 10; i++)
{
if (dataGridView1.Rows.Count > i)
{
if (i == 1)
dataGridView1.Rows[i].DefaultCellStyle.ForeColor = Color.Red;
else if (i == 2)
dataGridView1.Rows[i].DefaultCellStyle.ForeColor = Color.Blue;
else
dataGridView1.Rows[i].DefaultCellStyle.ForeColor = Color.Green;
}
}
A: You may handle different events of your datagrid and set cell style

return;
e.CellStyle.BackColor = Color.Red;

d7407 | train | The solution to to make a list of the indexes that match and populate it in your for loop.
then after the for loop is done, print out the results
List<Integer> foundIndexes = new ArrayList<>();
for (x = 0; x < v; x++) {
if (c[x] == xx) {
foundIndexes.add(x);
}
}
//now we looped through whole array
if(foundIndexes.isEmpty()){
System.out.print("array not found");
}else{
System.out.print("array " + xx + " found at index : ");
for(Integer i : foundIndex){
System.out.print(i + ",");
}
}
This will print out array 2 is found at index 0,2, with a trailing comma. It's slightly more complicated to not have a trailing comma at the last index but I will leave that up to you to figure out.
A: You can also use StringBuilder if all you care is to output the indexes.
StringBuilder sb = new StringBuilder("array" + xx +" is found at index: ");
for (x = 0; x < v; x++) {
if (c[x] == xx) {
sb.append(x).append(",");
}
}
if (sb.charAt(sb.length() - 1) == ',') {
sb.deleteCharAt(sb.length() - 1);
System.out.println(sb);
} else {
System.out.println("array not found");
}
A: If I understand correctly the problem is the following:
You have elements in an array, you want to check if a particular value is in more than once position of the array, your problem is if you simply remove the break statement, it shows a message every time you don't find the desired number, that's frankly the only problem I see with removing the break statement.
Personally, what I'd do one of these two things:
Option A: You can create a boolean variable that changes if you find a number, then wait to deliver the "array not found" message until you have stopped searching for it, like this:
boolean found = false;
for( x=0; x<v; x++)
{
if(c[x] == xx)
{
System.out.println("array " + xx + " found at index :"+x);
found = true;
}
}
if (found = false)
{
System.out.println("array not found");
}
println does the same as print, only it introduces a \n at the end, so the response looks like this:
array 2 found at index :0
array 2 found at index :2
Instead of:
array 2 found at index :0
array 2 found at index :2
Option B: Probably more elegant solution would be to create other array that store the positions in which you have found the element you are looking for, then print them all at once, you could do this going over the array twice (one to count how many positions the array has to have, another to check the positions of the elements) or simply use an ArrayList, but since this looks like learning material I'm going to guess that's out of the question.
Also if it is possible, try to word your question better because I'm still not even sure if this is what you are asking. | unknown | |

d7411 | train | ABRecord is an opaque C type. It is not an object in the sense of Objective-C. That means you can not extend it, you can not add a category on it, you can not message it. The only thing you can do is call functions described in ABRecord Reference with the ABRecord as a parameter.
You could do two things to be able to keep the information referenced by the ABRecord arround:
*
*Get the ABRecords id by ABRecordGetRecordID(). The ABRecordID is defined as int32_t so you can cast it to an NSInteger and store it wherever you like. You can later get the record back from ABAddressBookGetPersonWithRecordID () or ABAddressBookGetGroupWithRecordID(). But aware, the record could be changed or even deleted by the user or another app meanwhile.
*Copy all values inside the record to a standard NSObject subclass and use NSCoding or other techniques to store it. You will then of cause not benefit from changes or additions to the record the user could have made.
Of cause you can combine both approaches. | unknown | |

d7415 | train | You can check that by imply calling getImageData() or even just fillRect() right after your drawImage() call.
If the returned ImageData is empty, or if there is no rect drawn over your video frame, then, yes, it might be async, which would be a terrible bug that you should report right away.

A: When your match fails, In the link to Mastering Perl that you provide, I wrote:
I have a way to get around Perl resetting the match position. If I want to try a match without resetting the starting point even if it fails, I can add the /c flag, which simply means to not reset the match position on a failed match. I can try something without suffering a penalty. If that doesn’t work, I can try something else at the same match position. This feature is a poor man’s lexer.

// eslint-disable-next-line import/prefer-default-export
export const mount = (el, props) =>
new window.Vue({
el,
render: h => h(Filter, {props})

2) using rollup to generate the code (I think it's a better fit for generating libraries)
{
input: `./src/${widgetName}/${widgetName}.js`, // Path relative to package.json
output: {
format: 'umd',
name: widgetName,
file: `./dist/${widgetName}.js`,
exports: 'named',
external: ['vue'], // requires vuejs lib to be loaded separately
globals: {
vue: 'Vue',

},
//... etc

3) add to html
<script src="/dist/vue.js"></script>
<script src="/dist/mywidgit.js"></script>
<!-- mywidgit mount target-->
<div id="widget1"></div>
<!-- init and mount -->
<script>

d7431 | train | My simple explanation of what props.children does is that it is used to display whatever you include between the opening and closing tags when invoking a component.
change your function component to
function Item(props) {
return (
<div>
{props.children}
<div>
);
}
Reference : react's props children
A: @Kirill I hope this will help you .
function Item({ value, children }) {
return (
<div>
{/* not relevant code here */}
{children}
<div>
);
}
Then you can call your Item like this:
<Item value="foo">Foo</Item>
<Item value="bar">Bar</Item>
<Item value="baz">Baz</Item>
also you can pass other element as children to your Item Component also:
<Item value="foo">
<p>Foo</p>
</Item>
A: You can destructure the component children from props.
function Item({ value, children }) {
return <div><p>{children}: {value}</p></div>;
}
function Example() {
return (
<div>
<Item value="foo">Foo</Item>
<Item value="bar">Bar</Item>
<Item value="baz">Baz</Item>
</div>
);

d7433 | train | The palindrome_below definition is an instance method on Fixnum. An instance method is a function that can be called on an instance of a class (in contrast to a class method, which is called on the class itself).
Given this code, any instance of Fixnum will have access to palindrome_below method whereinself refers to the Fixnum instance itself (and i refers to the argument being passed to the method call).
14.palindrome_below(5)
#=> [1, 2, 3, 4, 6, 12] # `self` refers to the Fixnum `14`
Consequently, the output below is identical to the example above:
(1...14).select{|f| f.to_s(5) == f.to_s(5).reverse}
#=> [1, 2, 3, 4, 6, 12]
A: x...y creates a Range with the interval (x, y]. In your context, self is referring to an instance of Fixnum.
Any integer that can be represented in one native machine word is an instance of Fixnum. Here is a simple example:
class Fixnum
def double
self * 2

# self is `2`

d7434 | train | My process to do such a transition was gradual, I had a similar Grunt configuration.
These are my notes & steps in-order to transition to Webpack stack.
The longest step was to refactor the code so it will use ES6 imports/exports (yeah, I know you have said that it is not a phase that you wanna make, but it is important to avoid hacks).
At the end each file looks like that:
//my-component.js
class MyComponentController { ... }
export const MyComponent = {
bindings: {...},
controller: MyComponentController,
template: `...`
}
//main.js
import {MyComponent} from 'my-component'
angular.module('my-module').component('myComponent', MyComponent);
In order not going over all the files and change them, we renamed all js files and added a suffix of .not_module.js.
Those files were the old untouched files.
We added grunt-webpack as a step to the old build system (based on Grunt).
It processed via Webpack all the new files (those that are without .not_module.js suffix).
That step produced only one bundle that contains all the files there were converted already, that file we have added to concat step.
One by one, each converted file gradually moved from being processed by Grunt tasks to be processed by Webpack.
You can take as a reference that webpack.config.
Good luck. | unknown | |

A: It seems like you are asking if you are on a Linux machine you want to query to localhost and have that query forwarded to a SQL Server. In this case the above answer is partially correct and will allow packets to be forwarded but doesn't actually perform the forward/redirect. You also say "SQL Server" which I take to mean MS SQL Server. The default port in this case is listed as 1433. You would actually need (2) rules:
# iptables -t nat -A PREROUTING -p tcp -i lo -d localhost --dport 1433 -j DNAT --to-destination x.x.x.x # where x.x.x.x is the SQL Server IP address
# iptables -A FORWARD -i lo -p tcp --dport -j ACCEPT # only if your default FORWARD policy is DROP. Otherwise you just need the prerouting rule. | unknown | |

It appears that with a GridView you can't initiate the drag horizontally, you have to do it vertically and it's the exact opposite with the ListView.
So if you want to drag 'n drop items horizontally you have to use a ListView. (as recommended in the MS guidelines http://msdn.microsoft.com/en-us/library/windows/apps/hh465299.aspx )

d7443 | train | Basically the problem is, as I understand, that you're trying to open your .html template directly from IDEA. Which means you're not using the thymeleaf engine to render it - you're just opening the template itself and not the resulting page. If you open the source code of this page using your browser's dev tools, you will see that all your expressions stay unprocessed which leads to it trying to fetch the resources on the wrong port (e.g. 63342 instead of 8080 where your application is really running and is ready to serve the resources).
Thus, you cannot edit your templates like this. But Thymeleaf does have an option to do that. If you're running your Spring Boot application from the IDE directly (e.g. a profile in Intellij IDEA Ultimate) you can add the following to your application.properties:
spring.thymeleaf.cache=false
This will tell your Spring template resolver that you do not want to cache your .html templates and it will load the files from disk every time, so if you modify your template and then hit IDE's build button it should re-package your template and when you refresh your page in browser it will load (and process!) the edited one.
Caution! Only use this for development builds, set value to true for production environments to prevent unnecessary re-reading.
See Spring Boot Docs on Hot Swapping for more.

d7450 | train | Welcome to SO.
Why do you not want the error?
If you just don't want to see the error, then you could always just throw it away with 2>/dev/null, but PLEASE don't do that. Not every error is the one you expect, and this is a debugging nightmare. You could write it to a log with 2>$logpath and then build in logic to read that to make certain it's ok, and ignore or respond accordingly --
mv *.json /dir/ 2>$someLog
executeMyLogParsingFunction # verify expected err is the ONLY err
If it's because you have set -e or a trap in place, and you know it's ok for the mv to fail (which might not be because there is no file!), then you can use this trick -
mv *.json /dir/ || echo "(Error ok if no files found)"
or
mv *.json /dir/ ||: # : is a no-op synonym for "true" that returns 0
see https://www.gnu.org/software/bash/manual/html_node/Conditional-Constructs.html
(If it's failing simply because the mv is returning a nonzero as the last command, you could also add an explicit exit 0, but don't do that either - fix the actual problem rather than patching the symptom. Any of these other solutions should handle that, but I wanted to point out that unless there's a set -e or a trap that catches the error, it shouldn't cause the script to fail unless it's the very last command.)
Better would be to specifically handle the problem you expect without disabling error handling on other problems.
shopt -s nullglob # globs with no match do not eval to the glob as a string
for f in *.json; do mv "$f" /dir/; done # no match means no loop entry
c.f. https://www.gnu.org/software/bash/manual/html_node/The-Shopt-Builtin.html
or if you don't want to use shopt,
for f in *.json; do [[ -e "$f" ]] && mv "$f" /dir/; done
Note that I'm only testing existence, so that will include any match, including directories, symlinks, named pipes... you might want [[ -f "$f" ]] && mv "$f" /dir/ instead.
c.f. https://www.gnu.org/software/bash/manual/html_node/Bash-Conditional-Expressions.html
A: This is expected behavior -- it's why the shell leaves *.json unexpanded when there are no matches, to allow mv to show a useful error.
If you don't want that, though, you can always check the list of files yourself, before passing it to mv. As an approach that works with all POSIX-compliant shells, not just bash:
#!/bin/sh
# using a function here gives us our own private argument list.
# that's useful because minimal POSIX sh doesn't provide arrays.
move_if_any() {
dest=$1; shift # shift makes the old $2 be $1, the old $3 be $2, etc.
# so, we then check how many arguments were left after the shift;
# if it's only one, we need to also check whether it refers to a filesystem
# object that actually exists.
if [ "$#" -gt 1 ] || [ -e "$1" ] || [ -L "$1" ]; then
mv -- "$@" "$dest"
fi
}
# put destination_directory/ in $1 where it'll be shifted off
# $2 will be either nonexistent (if we were really running in bash with nullglob set)
# ...or the name of a legitimate file or symlink, or the string '*.json'
move_if_any destination_directory/ *.json
...or, as a more bash-specific approach:
#!/bin/bash
files=( *.json )
if (( ${#files[@]} > 1 )) || [[ -e ${files[0]} || -L ${files[0]} ]]; then
mv -- "${files[@]}" destination/
fi

d7451 | train | Search, don't categorise.
You can display the control as a simple text box, and when the user types in a few characters, you could pop up an autocomplete-like dropdown to select the final value. Here's a link to the jQuery plugin for autocomplete.
A: I really wouldn't have a 30,000 element drop-down. The GUI is supposed to make it easier on the user rather than harder.
If you have no other way to categorise the data other than alphabetically, you're not restricted to using a two-stage approach with just the first character. Make it reliant on the first two characters.
This would give you at most 676 (assuming alphas only) in the first drop-down and (on average) 44 in the second.
We've actually taken two approaches to this problem. BIRT (which we use) allows for cascading parameters which can easily run that second-level query whenever you change the first drop-down box.
However, some of our customers care absolutely zero for nice GUI stuff (other than the output of nice 9-point Verdana and beautiful charts to placate management, of course). They prefer a free-form text entry field where they can just type in "SYS_PAX_%" to change their queries.
Of course, these are the customers that know exactly what data is in their database and use values which lend themselves to categorisation with SQL LIKE clauses. Others prefer the ability to search.
A: I had this same question about 2 years ago concerning a asp.net dropdown box.
Trust me, don't even try it. Use the auto complete suggestions above. I've found that displaying anything above 5000 records tends to crash the browser.
Just my 2 cents.
A: +1 @pax. Still i'd like to see a 30K dropdown! :)
@JustAProgrammer, perhaps you could do a text box where people can type in the beginning of what they are looking for and you can filter as they type in.
A: If you're asking from a performance perspective rather than a usability perspective I would consider using a live-list approach that loads only a subset of the list items on demand as you scroll up or down. If the user clicks down the list quickly, to say the middle, it will load another 10 elements corresponding to that position. Both render time and load time will be much faster.
Like paging, but 'fluid'.
A: Auto complete drop down as suggested above is best to have. But it will require the users to have some idea about the type of entries to start with. If the users are familiar with data, go for it.
Alternatively, if you can categorize your data, then you can start with the categories first and then based on the selection you can populate the dependent drop down with actual values which will be a subset of original values. | unknown | |
d7452 | train | formGroup expects a FormGroup instance means that you did not create an instance for the FormGroup defined in your template which is signupForm

// arg2 - single validator or an array of validators

You should change the reference of sigupForm to signupForm instead.
A: In my case, I was using Reactive Forms and loading the data for form asynchronously from a service. But, the form template will start getting generated parallelly.

d7455 | train | You can turn your numbers into strings and then sort them.
Afterwards if one number is a pre-number all numbers that start with it will follow and once a number does not start with it anymore you found all.
Example_List=[112,34533344,11234543,98]
list_s = sorted(str(i) for i in Example_List)
result = []
for i in range(len(list_s)):
k=i+1
while k<len(list_s) and list_s[k].startswith(list_s[i]):
result.append((list_s[i],list_s[k]))
k += 1
print(result)
A: If you want to find all numbers, starting with any number from your list you could do something like this:
#Converte your list of ints to list of strings
tmp = map(lambda x : str(x),l)
#Use a set so you duplicate entries are eliminated
result = set()
for x in tmp:
#Insert all numbers starting with the current one
result.update([y for y in filter(lambda z : z.startswith(x) and z != x, l)])
#Convert your set of ints to a list of strings
result = list(map(int, result))
A: A single list comprehension will return all numbers in your list (as integers) which start with a specified "pre-number":
In [1]: Example_List=[112,34533344,11234543,98]
In [2]: [num for num in Example_List if str(num).startswith('112')]
Out[2]: [112, 11234543]
If your pre-number is always the first entry in your list but may be different for different lists then you can still do it in one line, but it's a little longer:
In [3]: [num for num in Example_List[1:] if str(num).startswith(str(Example_List[0]))]
Out[3]: [11234543] | unknown | |

Yes, because that's exactly what your code does:
defaults.setObject(existingArr, forKey: "D")
But what is existingArr? It's the defaults you've just loaded before:
if var existingArr = NSUserDefaults.standardUserDefaults().arrayForKey("D") as? [String]
So what happens is that when you enter the .contains branch, you always do the same operation: you save the existing array.
Contrary to what your comment in the code states, you're not appending anything to any array in that block, you're saving the existing one. | unknown | |

d7467 | train | My understanding is that destroy() is fired and that should remove the
content script, but if I look in the debugger in dev tools, the script
is still listed after I disable.
I can remove the listeners and the observers when handling the detach
event, but my understanding was that the content script is removed
during the detach so the listeners, should be removed?
This is a very good question.
The detach event is event is meant to let you know it's time to clean your content script. Event listeners need to be removed, anything added to the window scope should also be removed,
You don't need to let the main.js script know when you are done. | unknown | |
d7468 | train | Mostly it's a problem with to big association filters.
Disable the auto created filters and reenable them one by one, to find the problem filter.
This will help you if your filter is not to big:
filter :foo, as: :select, collection: Foo.pluck(:name, :id)
(but works only for rails > 4.0, you can build a similar thing by hand in rails 3.x)
A: Yes, this is usualy because of auto created filters, you can disable filters by:
remove_filter :some_param
Also you can eager-load some association with include in scoped collection, and if you have a huge count of records may be it can help to set:

d7470 | train | Because I had simmilar problems and needed a lot of time to fix it, I will summarize the important facts for getting it running:
*
*Install doxygen AND graphviz
*Add the bin directory of graphviz to your windows path variable (e.g. C:\Program Files (x86)\Graphviz2.38\bin)
*In the Settings.ini located in the graphviz bin directory, also set the path (e.g. binPath=C:\Program Files (x86)\Graphviz2.38\bin)
*In doxygen, under the tab "Expert" -> Dot check "HAVE_DOT"
*In doxygen, under the tab "Expert" -> Dot set "DOT_PATH" to your graphviz bin directory like above
These steps did it to make it working for me.
A: I know you found your solution, but for the sake of people like myself coming from Google, I'd like to make this as easy as possible for everyone.
If you're on Windows, and have installed both Doxygen and Graphviz, or if you're on Linux and have used apt-get install doxygen graphviz, the next step is to make sure that you're able to run the dot command from the command prompt/terminal. You can do this by making sure that the Graphviz/bin folder is appended to your PATH file.
Refer to this answer (removed by SO so here is a archive.org link) if you need more details on how to properly set up Doxygen/Graphviz for visualizations
A: On Windows 10 in 2017, I needed to:
*
*Install graphviz from http://graphviz.org/
*In the Dot heading under the Doxygen expert tab, populate DOT_PATH with "C:\Program Files (x86)\Graphviz2.38\bin"
*In the Diagrams heading under the Doxygen Wizard tab, select "Use dot tool from the GraphVizPackage"
A: *
*Go to Control Panel and search for Edit System Environment Variables
*Go to System Properties -> Environment settings -> Path
*Add the path to your Graphviz bin folder at the end of the Path variables.
They are separated with a semicolon ";"
See example below, where I added:
; C:\Program Files (x86)\Graphviz2.38\bin
Alternatively you can use the Setx command from the command window. | unknown | |
d7471 | train | Apparently the issue was caused by the fact that an old version of the translation jsons was cached in the dist folder of my Angular project.

d7472 | train | So you want to react to some events happening in the UI. First things first: if you want, in reaction, to change only your view/layout, you do not need ICommand and a simple event handler will do the trick. If you expect to change the underlying data (your view model) in reaction to that event, you can use an ICommand or an event handler, as described below.
Let's first define a simple view model for our MainWindow:
public class MyViewModel {
/// <summary>
/// Command that performs stuff.
/// </summary>
public ICommand MyCommand { get; private set; }
public MyViewModel() {
//Create the ICommand
MyCommand = new RelayCommand(() => PerformStuff());
}
public void PerformStuff() {
//Do stuff that affects your view model and model.
//Do not do anything here that needs a reference to a view object, as this breaks MVVM.
Console.WriteLine("Stuff performed in ViewModel.");
}
}
This assumes that you have a RelayCommand implementation of the ICommand interface that lets you invoke Action delegates on Execute:
public class RelayCommand : ICommand {
//Saved Action to invoke on Execute
private Action _action;
/// <summary>
/// ICommand that always runs the passed <paramref name="action"/> when executing.
/// </summary>
/// <param name="action"></param>
public RelayCommand(Action action) {
_action = action;
}
#region ICommand
public event EventHandler CanExecuteChanged;
public bool CanExecute(object parameter) => true;
public void Execute(object parameter) => _action.Invoke();
#endregion
}
In your MainWindow.xaml, we define two Border objects: the first one operates on the view model through an event handler, the second one through the ICommand pattern:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<!--Performs action on click through event handler-->
<Border Grid.Row="0" MouseUp="Border_MouseUp" Background="Red"></Border>
<!--Performs action on click through ICommand-->
<Border Grid.Row="1" Background="Blue">
<Border.InputBindings>
<MouseBinding MouseAction="LeftClick" Command="{Binding MyCommand}"></MouseBinding>
</Border.InputBindings>
</Border>
</Grid>
In your MainWindow.xaml.cs, assign a view model object and define the event handler for mouse up event:
public partial class MainWindow : Window {
public MainWindow() {
InitializeComponent();
DataContext = new MyViewModel(); ;
}
//Handles mouse up event on the first Border
private void Border_MouseUp(object sender, System.Windows.Input.MouseButtonEventArgs e) {
//...
//Do stuff that affects only your view here!
//...
//Now the stuff that affects the view model/model:
((MyViewModel)DataContext).PerformStuff();
}
}
Clicking on any of the two Border objects will perfom stuff on your view model.
How to apply this to your specific control and event?
*
*You can always use a custom event handler DockingManager_LayoutChanged as shown above.
*If you want to use the ICommand and your event is something else than a mouse or keyboard event, you can achieve the binding by following this instead of using a MouseBinding.
A: For such scenarios I always write attached properties.
For example for the Loaded-Event of a Window I use the following attached property:
internal class WindowExtensions
{
public static readonly DependencyProperty WindowLoadedCommandProperty = DependencyProperty.RegisterAttached(
"WindowLoadedCommand", typeof(ICommand), typeof(WindowExtensions), new PropertyMetadata(default(ICommand), OnWindowLoadedCommandChanged));
private static void OnWindowLoadedCommandChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
Window window = d as Window;
if (window == null)
return;
if (e.NewValue is bool newValue)
{
if (newValue)
{
window.Loaded += WindowOnLoaded;
}
}
}
private static void WindowOnLoaded(object sender, RoutedEventArgs e)
{
Window window = sender as Window;
if (window == null)
return;
ICommand command = GetWindowLoadedCommand(window);
command.Execute(null);
}
public static void SetWindowLoadedCommand(DependencyObject element, ICommand value)
{
element.SetValue(WindowLoadedCommandProperty, value);
}
public static ICommand GetWindowLoadedCommand(DependencyObject element)
{
return (ICommand) element.GetValue(WindowLoadedCommandProperty);
}
}
In the viewmodel you have a standard command like:
private ICommand loadedCommand;
public ICommand LoadedCommand
{
get { return loadedCommand ?? (loadedCommand = new RelayCommand(Loaded)); }
}
private void Loaded(object obj)
{
// Logic here
}
And on the Window-Element in the XAML you write:
local:WindowExtensions.WindowLoadedCommand="{Binding LoadedCommand}"
local is the namespace where the WindowExtensions is located | unknown | |

d7476 | train | So the way fold works is that it accepts a list of function aliases on how to fold the next element in. if you don't provide it with a starting value, it uses the first element as the starting value. Quoting the documentation (emphasis mine):
The call fold!(fun)(range, seed) first assigns seed to an internal
variable result, also called the accumulator. Then, for each element
x in range, result = fun(result, x) gets evaluated. Finally, result
is returned. The one-argument version fold!(fun)(range) works
similarly, but it uses the first element of the range as the seed
(the range must be non-empty).
The reason why your original code didn't work is because you can't add an integer to a string (the seed was the first line of the file).
The reason why your latest version works (although only on 32-bit machines, since you can't reassign a size_t to an int on 64-bit machines) is because you gave it a starting value of 0 to seed the fold. So that is the correct mechanism to use for your use case.
The documentation is a bit odd, because the function is actually not an eponymous template, so it has two parts to the documentation -- one for the template, and one for the fold function. The fold function doc lists the runtime parameters that are accepted by fold, in this case, the input range and the seed. The documentation link for it is here: https://dlang.org/phobos/std_algorithm_iteration.html#.fold.fold
A: I was able to tweak the answer provied by Akshay. The following compiled and ran:
module example;
import std.stdio;
import std.algorithm.iteration : fold;
void main() {
string fileName = "test1.txt";
auto sum = File(fileName, "r")
.byLine
.fold!( (a, b) {
// You can define the lambda function using the `{}` syntax
auto len = b.length;
return a + len;
})(0); // Initialize the fold with a value of 0

d7478 | train | Broadly speaking, the advantage of splitting it up into more parts is that you can optimize your processor use.
If the dataset is split into 3 parts, one per processor, and they take the following time:
Split A - 10 min
Split B - 20 min
Split C - 12 min
You can see immediately that two of your processors are going to be idle for a significant amount of time needed to do the full analysis.
Instead, if you have 12 splits, each one taking between 3 and 6 minutes to run, then processor A can pick up another chunk of the job after it finishes with the first one instead of idling until the longest-running split finishes. | unknown | |

d7483 | train | You must have specified if the path to the directory is absolute or relative. If it is absolute, you can check with -e to see if it exists and with -d if the input given it is a directory or not.
if ( -e $dir and -d $dir) {

}
If the path is relative, then you must create the absolute path. For that you will have to use as $base your drvives (you need to do that for each drive) and after, use rel2abs to find an absolute path for the given relative path. If the folder exists, $abs_path will contain the absolute path, else it's value will be undef. Bellow as an example for searching your folder with a relative path on drive c:\:
$base = 'c:\';

d7487 | train | Raise an exception. Not only is it the appropriate way to signal an error, it's also more useful for debugging. The traceback includes the line which did the method call but also additional lines, line numbers, function names, etc. which are more useful for debugging than just a variable name. Example:
class A:
def do(self, x):
if x < 0:
raise ValueError("Negative x")
def wrong(a, x):
a.do(-x)
wrong(A(), 1)
This gives a traceback similar to this, if the exception isn't caught:
Traceback (most recent call last):
File "...", line 1, in <module>
wrong(A(), 1)
File "...", line 7, in wrong
a.do(-x)
File "...", line 4, in do
raise ValueError("Negative x")
ValueError: Negative x
You can also use the traceback module to get this information programmatically, even without an exception (print_stack and friends).

print "\n[y.get_instance_name() for y in (bumbum,blah)] :\n",[y.get_instance_name() for y in (bumbum,blah)]
the result is
bumbum's names:
['bumbum']
map(lambda y:y.get_instance_name(), (bumbum,blah) :
[['bumbum'], ['blah']]
[y.get_instance_name() for y in (bumbum,blah)] :
[['bumbum', 'y'], ['blah', 'y']]
The second list comprehension shows that the function get_instance_name() must be used with care. In the list comp, identifier y is assigned in turn to every element of (bumbum,blah) then the finction finds it out as a name of the instance !
.
Now, a more complex situation:
ahah = A() # ahah : first name for this instance
class B(object):
pass
bobo = B()
bobo.x = ahah # bobo.x : second name for ahah
jupiter = bobo.x # jupiter : third name for ahah
class C(object):
def __init__(self):
self.azerty = jupiter # fourth name for ahah
ccc = C()
kkk = ccc.azerty # kkk : fifth name for ahah
bobo.x.inxnum = 1005
bobo.x.inxwhat = kkk # bobo.x.inxwhat : fifth name for ahah
# Since bobo.x is instance ahah, this instruction also
# creates attribute inxwhat in ahah instance's __dict__ .
# Consequently, instance ahah having already 5 names,
# this instruction adds 5 additional names, each one
# ending with .inxwhat
# By the way, this kkk being ahah itself, it results that ahah
# is the value of its own attribute inxwhat.
print ahah.get_instance_name()
result
['bobo.x', 'bobo.x.inxwhat',
'ahah', 'ahah.inxwhat',
'jupiter', 'jupiter.inxwhat',
'kkk', 'kkk.inxwhat',
'ccc.azerty', 'ccc.azerty.inxwhat']
I concur to judge this solution a little heavy and that if a coder thinks he needs such a heavy function, it is probably because the algorithm isn't optimal. But I find interesting to see that it's possible to do this in Python though it doesn't seem evident.
I say heavy, not hacky, I don't find it's hacky, by the way.
A: No, you can't. Objects can have any number of names, so the question doesn't even make sense. Consider:
a1 = a2 = a3 = A()
What is the name of the instance of A()? | unknown | |
d7488 | train | I believe your problem is this line:
df.index.name = 'Facility'
All this would do is name the existing df index (which looks like 0, 1, 2, 3...) "Facility," rather than taking the existing Facility column and making it the index. To do that, you'd want:
df = df.set_index('Facility')
I found this discrepancy by adding a bunch of print(df.head()) statements after each line where your code modified the dataset, and doing the same in the original Bokeh heatmap example, and looking for where they diverged. Might be useful in case there are other problems. | unknown | |

d7490 | train | Your javascript function is returning an object literal, not a JSON string. Probably you need to do the parallel in Java, which would be to return an instance of a class that contains a property named speech, which a getter and setter for speech, and with the value of speech set to "hello lambda java". AWS will probably take care of serializing that object to the JSON response you want.
More typing in Java than Javascript. Ha! I punned.
A: It doesn't really make sense but send the method something like "hello", not JSON. Lambda tries to be smarter than you and, if it sees something that looks like JSON it tries to parse it. But then you ask for a string so it gets confused. Personally I think this is a bug but since you can't pass a "Content-Type" it has to guess.
For reference, if I use this code:
public class HelloWorldLambdaHandler implements RequestHandler<String, String> {
public String handleRequest(String inputObject, Context context) {
context.getLogger().log("context logger - got \"" + inputObject + "\" from call");
return "{\"speech\": \"hello lambda java\"}";
}
}
and test with the string "hello" (yes, including the quotes) I get back what I expect in the Lambda test console. If I send:
{
"key3": "value3",
"key2": "value2",
"key1": "value1"

You can achieve maintaining new lines (basically text is wrapped), if some exists in the text.

d7493 | train | it seems cannot be done for now.
when consumeing the topic, consumers would get all tags
A: Tags are only stored in messages, there is no global place to store all tags of a topic, so only consumers can specify tags for filtering and consumption
A: You can't! Since there are no ways to save all tags in the broker.
Actually, you need not know all the tags when you consume. You should only care about the tag you know. If there are some tags that a consumer does not know, which means the messages with that tag should not be consumed by it. | unknown | |
d7494 | train | You want to filter the list based on the country column.
us_movies = [movie for movie in movies if movie[6] == 'USA']
You can also transform the line into just the title if you like.
us_movie_titles = [movie[0] for movie in movies if movie[6] == 'USA']
If you want a corresponding list of match predicate results, this will work:
is_match = [movie[6] == 'USA' for movie in movies]
Note, the size of the first two lists may be smaller than the original list, but is_match will have the same size and ordering as your original list.
To add the booleans to your full dataset:
movies_with_usa = [m[0] + [m[1]] for m in zip(movies, is_match)]
But what you really have is named data, so it's probably more appropriate in a dictionary or object. Also, if you're reading a csv file, a csv reader is part of the standard library. So for something a little more robust
import csv
def read_data(filename):
with open(filename) as f:
reader = csv.DictReader(f)
return [row for row in reader]
def match(record, field, value):
return record[field] == value
data = read_data("movie_metadata.csv")
us_movies = [record for record in data if match(record, 'country', 'USA')]
A: You want to use a pandas dataframe and then you can filter very easily based on the columns.
import pandas as pd
df = pd.DataFrame(movie_data[1:],columns = movie_data[0])

df[df.country == "USA"]

A: Just iterate over all movies and compare the 7th column:
made_usa = []
for l in movie_data:
if l[6] == 'USA':
made_usa.append(l)
print (made_usa)
To add only the movie name, it is just to do this:
made_usa = []
for l in movie_data:
if l[6] == 'USA':
made_usa.append(l[0])
print (made_usa)
To save if there is a match or not, you can use a dictionary like this:
made_usa = {}
for l in movie_data:
if l[6] == 'USA':
made_usa.update({l[0]: 'True'})
else:
made_usa.update({l[0]: 'False'})
print (made_usa)
After that, if you want to look if a certain move was made in USA or not. All you need to do is, for example:
print(made_usa['Avatar'])
Output:
'True'
A: Probably you are looking for a generic solution without any third party libraries (i.e. only standard library). Here we go:
def filter_by(csv_data, column_name, column_value):
indices = [i for i, name in enumerate(data[0]) if name == column_name]
if not indices:
return
index = indices[0]
for row in data[1:]:
if row[index] == column_value:
yield row
And this is how you use it:
print(list(filter_by(movie_data, "country", "USA")))
This shall output (I formatted it a bit for clarity):
[
['Avatar', 'James Cameron', 'Color', '178', 'CCH Pounder', 'English', 'USA', '2009'],
["Pirates of the Caribbean: At World's End", 'Gore Verbinski', 'Color', '169', 'Johnny Depp', 'English', 'USA', '2007']

d7495 | train | The preprocessorOptions.*.additionalData parameter will only work if there are already loaded/imported css to prepend to, so basically using both options of importing directly into your main.ts file for the bulk and any other preprocessing can be defined in the vite.config.js file.
Th documentation at https://vitejs.dev/config/#css-preprocessoroptions unfortunately does NOT explain this, which did tarnish a perfectly good Saturday night
A: I have had exactly the same problem. Although many vite vue 3 boilerplates do it the same way you and I do, strangely it didn't work, maybe it's a certain vite version that might have bugs.
The only thing that worked for me was the import in main.ts:
import { createApp } from 'vue'
import { createPinia } from 'pinia'
import App from './App.vue'
import router from './router'
//import your scss here
import "@/assets/scss/style.scss";
const app = createApp(App)
app.use(createPinia())
app.use(router)
app.mount('#app')
My versions:
sass: 1.49.8 (you only need the sass package here and not the loader)
vue: 3.2.29
A: Here's what worked for me:
If you haven't, install the Storybook builder for Vite (@storybook/builder-vite)
npm install @storybook/builder-vite --save-dev
or
yarn add --dev @storybook/builder-vite
Then in the .storybook/main.js file,
const { mergeConfig } = require('vite');
module.exports = {
async viteFinal(config, { configType }) {
// return the customized config
return mergeConfig(config, {
css: {
preprocessorOptions: {
scss: {
// Next line will prepend the import in all you scss files as you did with your vite.config.js file
additionalData: `@import "./src/styles/main";`,
},
},
},
});
},
// ... other options here
};
It is almost the same thing as you did, the trick here, is to add the same css.preprocessorOptions.scss object to the storybook configuration via mergeConfig in the main.js file in storybook.

d7496 | train | 1) Do not omit server side validation. MVC has some capabilities built in to do some of that for you on the server side, but it's a good idea to test that it's working. Normally this just tests for type, length, range, and some other basic validation. Any complex validation should be done by you. Either way TEST IT to make sure the correct validation is indeed occurring.
2) Json is most common since it works with JavaScript and is easy to serialize in .Net. I Recommend Newtonsoft.Json as your serialization library. You can use whatever language you can parse however, from protobuff to XML.
A ViewModel is a model that is sent to the view, for what the view needs and generally only goes one way, to the view.
The domain models are the objects you persist, and generally travel both ways, from client to server.
A good example might be that your view requires the current date, manager data, and employee data, so your view model contains properties for all of these, but the form only edits the employee which is a domain model that gets sent back from the client to the server to be persisted.
MVC has ModelBinders that will take your post data and turn them into whatever type you need (supposing you properly follow its conventions.) It's unlikely you'll have to map viewmodels to domain models. | unknown | |
d7497 | train | If you wrote the Apache startup-script yourself, you can include a check if the database instance is already running.
You can include a simple wait-loop:
MYSQL_OK=1
while ["$MYSQL_OK" -ne 0] ; do
echo "SELECT version();" | mysql -utestuser -ptestpassword testdb
MYSQL_OK=$?
sleep 5
done
Obivously you have to create some testuser and the test-database in Mysql:
CREATE DATABASE testdb;
GRANT USAGE,SELECT ON testdb.* TO 'testuser'@'localhost' IDENTIFIED BY 'testpassword';
FLUSH PRIVILEGES;
Simply put the while-loop somewhere in the start) part of your script. If your system is some kind of Redhat-system, you will notice that the start-script /etc/init.d/httpd has a line like this:
Required-Start: $local_fs $remote_fs $network $named
If you add $mysqld to that line, Apache will insist on a running mysqld before startup:
Required-Start: $local_fs $remote_fs $network $named $mysqld
However, the disadvantage is that the Apache startup will fail instead of waiting for running mylsqd.
