The fuzzer generates all possible ranges and\n\n/// validates them by matching a large number of test strings against them using\n\n/// the `regex` crate.

For example:\n\n///\n\n/// ```no_test\n\n/// a = [4]\n\n/// b = [7, 0, 5]\n\n/// ```\n\n///\n\n/// This means we need a regex that matches a number between 10 and 799. By\n\n/// looking at the first digit, we can deduce:\n\n///\n\n/// - The number can't start with 0 (leading zeros aren't allowed)\n\n/// - The number can start with 1, 2 or 3, but must be followed 1 or 2 more\n\n/// digit in that case\n\n/// - The number can be 4, 5 or 6, and can be followed by 0, 1 or 2 more digits\n\n/// - If the number starts with 7, it can be followed by\n\n/// - nothing\n\n/// - a zero, and possibly a third digit that is at most 5\n\n/// - a digit greater than zero, if there is no third digit.\n\n/// - If the number starts with 8 or 9, it can be followed by at most 1 more\n\n/// digit.\n\n///\n\n/// This is implemented recursively. We always remove the first digit from the\n\n/// slices. We then create a number of alternatives, each starting with a\n\n/// different digit or range of digits:\n\n///\n\n/// 1. `0 ..= ax-1`\n\n/// 2. `ax`\n\n/// 3. `ax+1 ..= bx-1`\n\n/// 4. `bx`\n\n/// 5. `bx+1 ..= 9`\n\n///\n\n/// If `ax` and `bx` are identical, 3. and 4. are omitted; if they're\n\n/// consecutive numbers, 3. is omitted. If `ax` is 0 or `bx` is 9, 1. or 5. is\n\n/// omitted, respectively. If `ax` is bigger than `bx`, the alternatives are a\n\n/// bit different, and this is important later:\n\n///\n\n/// 1. `0 ..= bx-1`\n\n/// 2. `bx`\n\n/// 3. `bx+1 ..= ax-1`\n\n/// 4. `ax`\n\n/// 5. `ax+1 ..= 9`\n\n///\n\n/// There is one more special case: The first digit in a number can't be 0,\n\n/// unless the range's lower bound is 0. So we check if we are currently looking\n\n/// at the first digit, and if that is the case, the first character class omits\n\n/// 0. If the lower bound is 0, then an alternative containing _only_ 0 is added\n\n/// _once_.\n\n///\n\n/// Now, for each of the above alternatives, we add two things: A character\n\n/// class matching the first digit, and _something_ matching the remaining\n\n/// digits. That _something_ is calculated by recursively calling the `range`\n\n/// function on the remaining digits. To make sure that this doesn't recurse for\n\n/// infinity, we must detect terminal calls (calls that stop recursing):\n\n///\n\n/// - If both slices are empty, we are done.\n\n///\n\n/// - If both slices contain exactly 1 digit, we simply add a character class\n\n/// matching a digit in that range.\n\n///\n\n/// - If the first slice is empty but not the second one, we apply a trick: We\n\n/// add a 0 to the lower bound and try again. Also, the returned\n\n/// sub-expression is made optional.\n\n///\n\n/// - For example, `range([4], [400])` at some point adds an alternative\n\n/// starting with `4` and calls `range([], [0, 0])` recursively. We want\n\n/// this to match the empty string, any single digit, or two zeros,\n\n/// because a \"4\" matching the range 4-400 can be followed by nothing, any\n\n/// single digit or two zeros.\n\n///\n\n/// If we just added a 0 to the lower bound, that would mean that the 4 MUST\n\n/// be followed by at least one more digit. We don't want that, so we make the\n\n/// expression following the 4 optional.\n\n///\n\n/// - If the second slice is empty but not the first, this is an error that\n\n/// should NEVER happen. The parser validates the input so that the upper\n\n/// bound can't be smaller/shorter than the lower bound.\n\n///\n\n/// Now, about the alternatives: This part is quite interesting. To recap, the\n\n/// alternatives are either this:\n\n///\n\n/// 1. `0 ..= ax-1`\n\n/// 2. `ax`\n\n/// 3. `ax+1 ..= bx-1`\n\n/// 4. `bx`\n\n/// 5. `bx+1 ..= 9`\n\n///\n\n/// or this, if `bx > ax`:\n\n///\n\n/// 1. `0 ..= bx-1`\n\n/// 2. `bx`\n\n/// 3. `bx+1 ..= ax-1`\n\n/// 4. `ax`\n\n/// 5. `ax+1 ..= 9`\n\n///\n\n/// Alternative 1 and 5 are the same, if we substitute `ax` and `bx` with\n\n/// `min(ax, bx)` in 1. and with `max(ax, bx)` in step 5:\n\n///\n\n/// ```no_test\n\n/// 1. [1-(min - 1)] [0-9]{la + 1, lb} (first digit)\n\n/// 1. [0-(min - 1)] [0-9]{la + 1, lb} (not first digit)\n\n/// 5. [(max + 1)-9] [0-9]{al, bl - 1}\n\n/// ```\n\n///\n\n/// (`la` and `lb` are the lengths of the remaining digits in the lower and\n\n/// upper bound, respectively).\n\n///\n\n/// What is the deal with the added or subtracted 1's? If we have a lower bound\n\n/// such as 533, the number must be at least 3 digits long, because the lower\n\n/// bound is three digits long. However, if the first digit is less than 5, it\n\n/// must be at least 4 digits long to be greater than 533. With the upper bound,\n\n/// it's the exact opposite: For example, with an upper bound of 6111, the\n\n/// number can be at most 3 digits if it starts with 7, 8 or 9.\n\n///\n\n/// I'm not going to explain the remaining alternatives (2 through 4), since you\n\n/// can understand them by reading the code.\n\n///\n\n/// The last step is to optimize the alternatives to be as compact as possible.\n\n/// This is achieved by simplifying and merging alternatives if possible. For\n\n/// example,\n\n///\n\n/// ```no_test\n\n/// [0-4] [5-9] | 5 [5-9]\n\n/// ```\n\n///\n\n/// This can be merged into `[0-5] [5-9]`. The rules are like addition and\n\n/// multiplication, where alternation (with `|`) is equivalent to `+` and\n\n/// concatenation is equivalent to `*`. This means we can use the distributive\n\n/// law: `a * x + b * x = (a + b) * x`. Note that we only do this if the first\n\n/// character class of each alternation are consecutive; for example,\n\n/// we merge `[0-4]` and `5`, but not `[0-4]` and `[6-9]`. This would be\n\n/// possible in theory, but would be computationally more expensive, since the\n\n/// second part of each alternation must be checked for equality.\n\n///\n\n/// The next optimization is to replace concatenation of equal elements with\n\n/// repetition. In other words, we replace `a + a` with `a * 2`, and `a + (a *\n\n/// 2)` with `a * 3`. This is important, because when we check whether two\n\n/// expressions are equal, it only works if they have the exact same structure:\n\n/// `[0-9][0-9]` is not considered equal to `[0-9]{2}`. So this optimization\n\n/// also serves as a _normalization_, to ensure that equal alternatives can be\n\n/// merged.\n\nfn range(a: &[u8], b: &[u8], is_first: bool, radix: u8) -> Result<Rule, Error> {\n\n let hi_digit = radix - 1;\n\n let lo_digit = if is_first { 1 } else { 0 };\n\n\n\n debug_assert!(a.len() <= b.len() && (a.len() < b.len() || a <= b));\n\n\n\n Ok(match (a.split_first(), b.split_first()) {\n\n (None, None) => Rule::Empty,\n\n (Some(_), None) => return Err(Error),\n\n (None, Some(_)) => range(&[0], b, false, radix)?.optional(),\n\n (Some((&ax, [])), Some((&bx, []))) => Rule::class(ax, bx),\n\n (Some((&ax, a_rest)), Some((&bx, b_rest))) => {\n\n let (min, max) = (u8::min(ax, bx), u8::max(ax, bx));\n\n let mut alternatives = vec![];\n\n\n\n if min > lo_digit && a_rest.len() < b_rest.len() {\n\n // 1.\n\n alternatives.push(vec![\n\n Rule::class(lo_digit, min - 1),\n\n Rule::class(0, hi_digit).repeat(a_rest.len() + 1, b_rest.len()),\n", "file_path": "rulex-lib/src/range.rs", "rank": 74, "score": 32559.362098643334 }, { "content": " CompileError { kind: self, span: Some(span) }\n\n }\n\n}\n\n\n\n/// Regex feature, possibly unsupported\n\n#[derive(Debug, Clone, Copy, PartialEq, Eq)]\n\n#[non_exhaustive]\n\npub enum Feature {\n\n NamedCaptureGroups,\n\n Lookaround,\n\n Grapheme,\n\n UnicodeBlock,\n\n UnicodeProp,\n\n Backreference,\n\n ForwardReference,\n\n RelativeReference,\n\n NonNegativeRelativeReference,\n\n NegativeShorthandW,\n\n}\n\n\n", "file_path": "rulex-lib/src/error/compile_error.rs", "rank": 75, "score": 32255.150621538774 }, { "content": " EmptyClassNegated,\n\n\n\n #[error(\"Capturing groups within `let` statements are currently not supported\")]\n\n CaptureInLet,\n\n\n\n #[error(\"References within `let` statements are currently not supported\")]\n\n ReferenceInLet,\n\n\n\n #[error(\"Variable doesn't exist\")]\n\n UnknownVariable,\n\n\n\n #[error(\"Variables can't be used recursively\")]\n\n RecursiveVariable,\n\n\n\n #[error(\"Compile error: {}\", .0)]\n\n Other(&'static str),\n\n}\n\n\n\nimpl CompileErrorKind {\n\n pub(crate) fn at(self, span: Span) -> CompileError {\n", "file_path": "rulex-lib/src/error/compile_error.rs", "rank": 76, "score": 32253.80391855259 }, { "content": "use crate::{options::RegexFlavor, span::Span};\n\n\n\nuse super::{Diagnostic, ParseError, ParseErrorKind};\n\n\n\n/// An error that can occur during parsing or compiling\n\n#[derive(Debug, Clone, thiserror::Error)]\n\npub struct CompileError {\n\n pub(super) kind: CompileErrorKind,\n\n pub(super) span: Option<Span>,\n\n}\n\n\n\nimpl CompileError {\n\n /// Create a [Diagnostic] from this error.\n\n pub fn diagnostic(self, source_code: &str) -> Diagnostic {\n\n Diagnostic::from_compile_error(self, source_code)\n\n }\n\n}\n\n\n\nimpl core::fmt::Display for CompileError {\n\n fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {\n", "file_path": "rulex-lib/src/error/compile_error.rs", "rank": 77, "score": 32252.474515390528 }, { "content": "\n\n #[error(\"Compile error: Unsupported feature `{}` in the `{:?}` regex flavor\", .0.name(), .1)]\n\n Unsupported(Feature, RegexFlavor),\n\n\n\n #[error(\"Group references this large aren't supported\")]\n\n HugeReference,\n\n\n\n #[error(\"Reference to unknown group.

This is the\n\n/// time spent computing the result of a query `q` minus the time spent in\n\n/// any other queries that `q` might have called. This \"self-time\" can be\n\n/// computed by looking at invocation stacks as follows:\n\n///\n\n/// When we encounter a query provider event, we first add its entire duration\n\n/// to the self-time counter of the query. Then, when we encounter a direct\n\n/// child of that query provider event, we subtract the duration of the child\n\n/// from the self-time counter of the query. Thus, after we've encountered all\n\n/// direct children we'll end up with the self-time.\n\n///\n\n/// For example, take the following query invocation trace:\n\n///\n\n/// <== q4 ==>\n\n/// <== q2 ==> <====== q3 ======>\n\n/// <===================== q1 =====================>\n\n/// -------------------------------------------------------> time\n\n///\n\n/// Query `q1` calls `q2` and later `q3`, which in turn calls `q4`. In order\n\n/// to get the self-time of `q1`, we take it's entire duration and subtract the\n\n/// durations of `q2` and `q3`. We do not subtract the duration of `q4` because\n\n/// that is already accounted for by the duration of `q3`.\n\n///\n\n/// The function below uses an algorithm that computes the self-times of all\n\n/// queries in a single pass over the profiling data. As the algorithm walks the\n\n/// data, it needs to keep track of invocation stacks. Because interval events\n\n/// occur in the stream at their \"end\" time, a parent event comes after all\n\n/// child events. For this reason we have to walk the events in *reverse order*.\n\n/// This way we always encounter the parent before its children, which makes it\n\n/// simple to keep an up-to-date stack of invocations.\n\n///\n\n/// The algorithm goes as follows:\n\n///\n\n/// ```\n\n/// for event in profiling_data.reversed()\n\n/// // Keep the stack up-to-date by popping all events that\n\n/// // don't contain the current event. After this loop, the\n\n/// // parent of the current event will be the top of the stack.\n\n/// while !stack.top.is_ancestor_of(event)\n\n/// stack.pop()\n\n///\n\n/// // Update the parents self-time if needed\n\n/// let parent = stack.top()\n\n/// if parent.is_some()\n\n/// self_time_for(parent) -= event.duration\n\n///\n\n/// // Update the self-time for the current-event\n\n/// self_time_for(event) += event.duration\n\n///\n\n/// // Push the current event onto the stack\n\n/// stack.push(event)\n\n/// ```\n\n///\n\n/// Here is an example of what updating the stack looks like:\n\n///\n\n/// ```\n\n/// <--e2--> <--e3-->\n\n/// <-----------e1----------->\n\n/// ```\n\n///\n\n/// In the event stream this shows up as something like:\n\n///\n\n/// ```\n\n/// [\n\n/// { label=e2, start= 5, end=10 },\n\n/// { label=e3, start=15, end=20 },\n\n/// { label=e1, start= 0, end=25 },\n\n/// ]\n\n/// ```\n\n///\n\n/// because events are emitted in the order of their end timestamps. So, as we\n\n/// walk backwards, we\n\n///\n\n/// 1. encounter `e1`, push it onto the stack, then\n\n/// 2. encounter `e3`, the stack contains `e1`, but that is fine since the\n\n/// time-interval of `e1` includes the time interval of `e3`. `e3` goes onto\n\n/// the stack and then we\n\n/// 3. encounter `e2`. The stack is `[e1, e3]`, but now `e3` needs to be popped\n\n/// because we are past its range, so we pop `e3` and push `e2`.\n\n///\n\n/// Why is popping done in a `while` loop? consider the following\n\n///\n\n/// ```\n\n/// <-e4->\n\n/// <--e2--> <--e3-->\n\n/// <-----------e1----------->\n\n/// ```\n\n///\n\n/// This looks as follows in the stream:\n\n///\n\n/// ```\n\n/// [\n\n/// { label=e2, start= 5, end=10 },\n\n/// { label=e4, start=17, end=19 },\n\n/// { label=e3, start=15, end=20 },\n\n/// { label=e1, start= 0, end=25 },\n\n/// ]\n\n/// ```\n\n///\n\n/// In this case when

E.g. `ed -p '> '` is\n\n now tokenized into `[\"ed\", \"-p\" \"'> '\"]`\n\n\n\n## [0.3.0] 2017-10-05\n\n\n\n### Changed\n\n\n\n- breaking: `execute` takes string to wait for as second argument \n\n (before it waited 10ms which was way too fragile)\n\n- if process doesn't end on SIGTERM a `kill -9` is sent after timeout is elapsed\n\n\n\n### Fixed\n\n\n\n- ctrl-* used to consume one line. As it could be that the reader did not consume all\n\n output data yet this could have been a not-yet-read line. Therefore `send_control`\n\n no longer consumes a line.\n\n\n\n## [0.2.0] 2017-09-20\n\n\n\n### Changed\n\n\n\nAll `exp_*` methods now also return the yet unread string and/or the matched string:\n\n\n\n- `exp_string`: return the yet unread string\n\n- `exp_regex`: return a tuple of (yet unread string, matched string)\n\n- `exp_eof` and `exp_nbytes`: return the yet unread string\n\n\n\n### Fixed\n\n\n\n- each execution of rexpect left a temporary file in /tmp/ this is now no longer the case\n\n- try_read was blocking when there was no char ready (!) -> fixed\n", "file_path": "CHANGELOG.md", "rank": 68, "score": 11.17992733065667 }, { "content": " self.exp_string(line)?;\n\n }\n\n Ok(bytes_written)\n\n }\n\n}\n\n\n\n// make PtySession's methods available directly\n\nimpl Deref for PtyReplSession {\n\n type Target = PtySession;\n\n fn deref(&self) -> &PtySession {\n\n &self.pty_session\n\n }\n\n}\n\n\n\nimpl DerefMut for PtyReplSession {\n\n fn deref_mut(&mut self) -> &mut PtySession {\n\n &mut self.pty_session\n\n }\n\n}\n\n\n", "file_path": "src/session.rs", "rank": 69, "score": 11.151372754742077 }, { "content": " .unwrap_or_else(|e| panic!(\"test_timeout failed: {}\", e));\n\n }\n\n\n\n #[test]\n\n fn test_expect_eof_timeout2() {\n\n let mut p = spawn(\"sleep 1\", Some(1100)).expect(\"cannot run sleep 1\");\n\n assert!(p.exp_eof().is_ok(), \"expected eof\");\n\n }\n\n\n\n #[test]\n\n fn test_expect_string() {\n\n || -> Result<()> {\n\n let mut p = spawn(\"cat\", Some(1000)).expect(\"cannot run cat\");\n\n p.send_line(\"hello world!\")?;\n\n p.exp_string(\"hello world!\")?;\n\n p.send_line(\"hello heaven!\")?;\n\n p.exp_string(\"hello heaven!\")?;\n\n Ok(())\n\n }()\n\n .unwrap_or_else(|e| panic!(\"test_expect_string failed: {}\", e));\n", "file_path": "src/session.rs", "rank": 70, "score": 10.41859808539761 }, { "content": "//! use rexpect::spawn;\n\n//! use rexpect::errors::*;\n\n//!\n\n//! fn do_ftp() -> Result<()> {\n\n//! let mut p = spawn(\"ftp speedtest.tele2.net\", Some(2000))?;\n\n//! p.exp_regex(\"Name \\\\(.*\\\\):\")?;\n\n//! p.send_line(\"anonymous\")?;\n\n//! p.exp_string(\"Password\")?;\n\n//! p.send_line(\"test\")?;\n\n//! p.exp_string(\"ftp>\")?;\n\n//! p.send_line(\"cd upload\")?;\n\n//! p.exp_string(\"successfully changed.\\r\\nftp>\")?;\n\n//! p.send_line(\"pwd\")?;\n\n//! p.exp_regex(\"[0-9]+ \\\"/upload\\\"\")?;\n\n//! p.send_line(\"exit\")?;\n\n//! p.exp_eof()?;\n\n//!

It's main components (depending on your need you can use either of those)\n\n//!\n\n//! - [session](session/index.html): automate stuff in Rust\n\n//! - [reader](reader/index.html): a non-blocking reader with buffering, matching on\n\n//! strings/regex/...\n\n//! - [process](process/index.html): spawn a process in a pty\n\n//!\n\n//! # Basic example\n\n//!\n\n//! ```no_run\n\n//!\n\n//! extern crate rexpect;\n\n//!\n", "file_path": "src/lib.rs", "rank": 77, "score": 7.456081365362024 }, { "content": "\n\n /// Read until needle is found (blocking!) and return tuple with:\n\n /// 1. yet unread string until and without needle\n\n /// 2. matched needle\n\n ///\n\n /// This methods loops (while reading from the Cursor) until the needle is found.\n\n ///\n\n /// There are different modes:\n\n ///\n\n /// - `ReadUntil::String` searches for string (use '\\n'.to_string() to search for newline).\n\n /// Returns not yet read data in first String, and needle in second String\n\n /// - `ReadUntil::Regex` searches for regex\n\n /// Returns not yet read data in first String and matched regex in second String\n\n /// - `ReadUntil::NBytes` reads maximum n bytes\n\n /// Returns n bytes in second String, first String is left empty\n\n /// - `ReadUntil::EOF` reads until end of file is reached\n\n /// Returns all bytes in second String, first is left empty\n\n ///\n\n /// Note that when used with a tty the lines end with \\r\\n\n\n ///\n", "file_path": "src/reader.rs", "rank": 78, "score": 7.137007595243794 }, { "content": "extern crate rexpect;\n\n\n\nuse rexpect::errors::*;\n\nuse rexpect::process::wait;\n\nuse rexpect::spawn;\n\n\n\n/// The following code emits:\n\n/// cat exited with code 0, all good!\n\n/// cat exited with code 1\n\n/// Output (stdout and stderr): cat: /this/does/not/exist: No such file or directory\n", "file_path": "examples/exit_code.rs", "rank": 79, "score": 7.0091878109764645 }, { "content": "use rexpect::spawn_stream;\n\nuse std::error::Error;\n\nuse std::net::TcpStream;\n\n\n", "file_path": "examples/tcp.rs", "rank": 80, "score": 6.655625574417714 }, { "content": " );\n\n assert_eq!(\n\n (\"\".to_string(), \"f\".to_string()),\n\n r.read_until(&ReadUntil::NBytes(4)).expect(\"4 bytes\")\n\n );\n\n }\n\n\n\n #[test]\n\n fn test_eof() {\n\n let f = io::Cursor::new(\"lorem ipsum dolor sit amet\");\n\n let mut r = NBReader::new(f, None);\n\n r.read_until(&ReadUntil::NBytes(2)).expect(\"2 bytes\");\n\n assert_eq!(\n\n (\"\".to_string(), \"rem ipsum dolor sit amet\".to_string()),\n\n r.read_until(&ReadUntil::EOF).expect(\"reading until EOF\")\n\n );\n\n }\n\n\n\n #[test]\n\n fn test_try_read() {\n", "file_path": "src/reader.rs", "rank": 81, "score": 6.514036754325989 }, { "content": "# rexpect\n\n\n\n[![Build Status](https://api.travis-ci.org/philippkeller/rexpect.svg?branch=master)](https://travis-ci.org/philippkeller/rexpect)\n\n[![crates.io](https://img.shields.io/crates/v/rexpect.svg)](https://crates.io/crates/rexpect)\n\n[![Released API docs](https://docs.rs/rexpect/badge.svg)](https://docs.rs/rexpect)\n\n[![Master API docs](https://img.shields.io/badge/docs-master-2f343b.svg)](http://philippkeller.github.io/rexpect)\n\n\n\n\n\nSpawn, control, and respond to expected patterns of child applications and processes, enabling the automation of interactions and testing. Components include:\n\n- **session**: start a new process and interact with it; primary module of rexpect.\n\n- **reader**: non-blocking reader, which supports waiting for strings, regex, and EOF.\n\n- **process**: spawn a process in a pty.\n\n\n\nThe goal is to offer a similar set of functionality as [pexpect](https://pexpect.readthedocs.io/en/stable/overview.html).\n\n\n\n## Maintainers wanted\n\n\n\nI have created rexpect as a project to learn rust and linux. But now due to some reasons I haven't used Rust in the past 2 years, so I can't keep up with the latest features/crate dependencies\n\n\n\nIt has become hard now to judge pull requests.
