Python-ripgrep

=====
This is a new minor version release of ripgrep that includes a couple very
minor breaking changes, a few new features and lots of bug fixes.

This version of ripgrep upgrades its `regex` dependency from `0.1` to `0.2`,
which includes a few minor syntax changes:

* POSIX character classes now require double bracketing. Previously, the regex
`[:upper:]` would parse as the `upper` POSIX character class. Now it parses
as the character class containing the characters `:upper:`. The fix to this
change is to use `[[:upper:]]` instead. Note that variants like
`[[:upper:][:blank:]]` continue to work.
* The character `[` must always be escaped inside a character class.
* The characters `&`, `-` and `~` must be escaped if any one of them are
repeated consecutively. For example, `[&]`, `[\&]`, `[\&\&]`, `[&-&]` are all
equivalent while `[&&]` is illegal. (The motivation for this and the prior
change is to provide a backwards compatible path for adding character class
set notation.)

Feature enhancements:

* Added or improved file type filtering for Crystal, Kotlin, Perl, PowerShell,
Ruby, Swig

=====
This is a new minor version release of ripgrep that includes two breaking
changes with lots of bug fixes and some new features and performance
improvements. Notably, if you had a problem with colors or piping on Windows
before, then that should now be fixed in this release.

**BREAKING CHANGES**:

* ripgrep now requires Rust 1.11 to compile. Previously, it could build on
Rust 1.9. The cause of this was the move from
[Docopt to Clap](https://github.com/BurntSushi/ripgrep/pull/233)
for argument parsing.
* The `-e/--regexp` flag can no longer accept a pattern starting with a `-`.
There are two work-arounds: `rg -- -foo` and `rg [-]foo` or `rg -e [-]foo`
will all search for the same `-foo` pattern. The cause of this was the move
from [Docopt to Clap](https://github.com/BurntSushi/ripgrep/pull/233)
for argument parsing.
[This may get fixed in the
future.](https://github.com/kbknapp/clap-rs/issues/742).

Performance improvements:

* [PERF 33](https://github.com/BurntSushi/ripgrep/issues/33):
ripgrep now performs similar to GNU grep on small corpora.
* [PERF 136](https://github.com/BurntSushi/ripgrep/issues/136):
ripgrep no longer slows down because of argument parsing when given a large
argument list.

Feature enhancements:

* Added or improved file type filtering for Elixir.
* [FEATURE 7](https://github.com/BurntSushi/ripgrep/issues/7):
Add a `-f/--file` flag that causes ripgrep to read patterns from a file.
* [FEATURE 51](https://github.com/BurntSushi/ripgrep/issues/51):
Add a `--colors` flag that enables one to customize the colors used in
ripgrep's output.
* [FEATURE 138](https://github.com/BurntSushi/ripgrep/issues/138):
Add a `--files-without-match` flag that shows only file paths that contain
zero matches.
* [FEATURE 230](https://github.com/BurntSushi/ripgrep/issues/230):
Add completion files to the release (Bash, Fish and PowerShell).

Bug fixes:

* [BUG 37](https://github.com/BurntSushi/ripgrep/issues/37):
Use correct ANSI escape sequences when `TERM=screen.linux`.
* [BUG 94](https://github.com/BurntSushi/ripgrep/issues/94):
ripgrep now detects stdin on Windows automatically.
* [BUG 117](https://github.com/BurntSushi/ripgrep/issues/117):
Colors should now work correctly and automatically inside mintty.
* [BUG 182](https://github.com/BurntSushi/ripgrep/issues/182):
Colors should now work within Emacs. In particular, `--color=always` will
emit colors regardless of the current environment.
* [BUG 189](https://github.com/BurntSushi/ripgrep/issues/189):
Show less content when running `rg -h`. The full help content can be
accessed with `rg --help`.
* [BUG 210](https://github.com/BurntSushi/ripgrep/issues/210):
Support non-UTF-8 file names on Unix platforms.
* [BUG 231](https://github.com/BurntSushi/ripgrep/issues/231):
Switch from block buffering to line buffering.
* [BUG 241](https://github.com/BurntSushi/ripgrep/issues/241):
Some error messages weren't suppressed when `--no-messages` was used.

=====
Bug fixes:

* [BUG 226](https://github.com/BurntSushi/ripgrep/issues/226):
File paths explicitly given on the command line weren't searched in parallel.
(This was a regression in `0.2.7`.)
* [BUG 228](https://github.com/BurntSushi/ripgrep/issues/228):
If a directory was given to `--ignore-file`, ripgrep's memory usage would
grow without bound.

=====
Bug fixes:

* Fixed a bug with the SIMD/AVX features for using bytecount in commit
`4ca15a`.
