Previously, ripgrep would only emit the 'bold' ANSI escape sequence if
no foreground or background color was set. Instead, it would convert colors
to their "intense" versions if bold was set. The intent was to do the same
thing on Windows and Unix. However, this had a few negative side effects:
1. Omitting the 'bold' ANSI escape when 'bold' was set is surprising.
2. Intense colors can look quite bad and be hard to read.
To fix this, we introduce a new setting called 'intense' in the --colors
flag, and thread that down through to the public API of the `termcolor`
crate. The 'intense' setting has environment specific behavior:
1. In ANSI mode, it will convert the selected color to its "intense"
variant.
2. In the Windows console, it will make the text "intense."
There is no longer any "smart" handling of the 'bold' style. The 'bold'
ANSI escape is always emitted when it is selected. In the Windows
console, the 'bold' setting now has no effect. Note that this is a
breaking change.
Fixes#266, #293
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`.
Fixes#136, Fixes#189, Fixes#210, Fixes#230
This flag is similar to what's found in grep: it will suppress all error
messages, such as those shown when a particular file couldn't be read.
Closes#149
Closes#26.
Acts like --count but emits only the paths of files with matches,
suitable for piping to xargs. Both mmap and no-mmap searches terminate
after the first match is found. Documentation updated and tests added.
