When give an explicit file path on the command line like `foo` where `foo`
is a symlink, ripgrep should follow it even if `-L` isn't set. This is
consistent with the behavior of `foo/`.
Fixes#256
When ripgrep detects a literal, it emits them as raw hex escaped byte
sequences to Regex::new. This permits literal optimizations for arbitrary
byte sequences (i.e., possibly invalid UTF-8). The problem is that
Regex::new interprets hex escaped byte sequences as *Unicode codepoints*
by default, but we want them to actually stand for their raw byte values.
Therefore, disable Unicode mode.
This is OK, since the regex is composed entirely of literals and literal
extraction does Unicode case folding.
Fixes#251
This changes the uppercase literal detection for the "smart case"
functionality. In particular, a character class is considered to have an
uppercase literal if at least one of its ranges starts or stops with an
uppercase literal.
Fixes#229
This is to ensure that we don't silently update a minor version of clap,
which could include a breaking change.
(An update to 2.19 should be done soon.)
I spent some quality time on my Windows 10 laptop and it appears to
suffer from a similar trade-off as on Linux: mmaps are bad for large
directory traversals but good for single large files.
Darwin continues to reject memory maps in all cases (unless explicitly
requested), but more testing should be done there.
This commit completely guts all of the color handling code and replaces
most of it with two new crates: wincolor and termcolor. wincolor
provides a simple API to coloring using the Windows console and
termcolor provides a platform independent coloring API tuned for
multithreaded command line programs. This required a lot more
flexibility than what the `term` crate provided, so it was dropped.
We instead switch to writing ANSI escape sequences directly and ignore
the TERMINFO database.
In addition to fixing several bugs, this commit also permits end users
to customize colors to a certain extent. For example, this command will
set the match color to magenta and the line number background to yellow:
rg --colors 'match:fg:magenta' --colors 'line:bg:yellow' foo
For tty handling, we've adopted a hack from `git` to do tty detection in
MSYS/mintty terminals. As a result, ripgrep should get both color
detection and piping correct on Windows regardless of which terminal you
use.
Finally, switch to line buffering. Performance doesn't seem to be
impacted and it's an otherwise more user friendly option.
Fixes#37, Fixes#51, Fixes#94, Fixes#117, Fixes#182, Fixes#231
There were two important reasons for the switch:
1. Performance. Docopt does poorly when the argv becomes large, which is
a reasonable common use case for search tools. (e.g., use with xargs)
2. Better failure modes. Clap knows a lot more about how a particular
argv might be invalid, and can therefore provide much clearer error
messages.
While both were important, (1) made it urgent.
Note that since Clap requires at least Rust 1.11, this will in turn
increase the minimum Rust version supported by ripgrep from Rust 1.9 to
Rust 1.11. It is therefore a breaking change, so the soonest release of
ripgrep with Clap will have to be 0.3.
There is also at least one subtle breaking change in real usage.
Previous to this commit, this used to work:
rg -e -foo
Where this would cause ripgrep to search for the string `-foo`. Clap
currently has problems supporting this use case
(see: https://github.com/kbknapp/clap-rs/issues/742),
but it can be worked around by using this instead:
rg -e [-]foo
or even
rg [-]foo
and this still works:
rg -- -foo
This commit also adds Bash, Fish and PowerShell completion files to the
release, fixes a bug that prevented ripgrep from working on file
paths containing invalid UTF-8 and shows short descriptions in the
output of `-h` but longer descriptions in the output of `--help`.
