When writing paths like `!/foo` in gitignore files (or when using the
-g/--glob flag), the presence of `!` would prevent the gitignore builder
from noticing the leading slash, which causes absolute path matching to
fail.
Fixes#405
The --max-filesize option allows filtering files which are larger than
the specified limit. This is potentially useful if one is attempting to
search a number of large files without common file-types/suffixes.
See #369.
A maximum filesize can be specified as an argument to a `WalkBuilder`.
If a file exceeds the specified size it will be ignored as part of the
resulting file/directory set.
The filesize limit never applies to directories.
This commit fixes two issues. The first issue is that if a file contained
many NUL bytes without any LF bytes, then the InputBuffer would read the
entire file into memory. This is not typically a problem, but if you run
rg on /proc, then bad things can happen when reading virtual memory mapping
files. Arguably, such files should be ignored, but we should also try to
avoid exhausting memory too. We fix this by pushing the `-a/--text` flag
option down into InputBuffer, so that it knows to stop immediately if it
finds a NUL byte.
The other issue this fixes is that binary detection is now applied to every
buffer instead of just the first one. This helps avoid detecting too many
files as plain text if the first parts of a binary file happen to contain
no NUL bytes. This issue still persists somewhat in the memory map
searcher, since we probably don't want to search the entire file upfront
for NUL bytes before actually performing our search. Instead, we search the
first 10KB for now.
Fixes#52, Fixes#311
This is essentially a rename of the existing `Stdout` type to `StandardStream`
and a change of its constructor from a single `new()` function to have two
`stdout()` and `stderr()` functions.
Under the hood, we add add internal IoStandardStream{,Lock} enums that allow
us to abstract between Stdout and Stderr conveniently. The rest of the needed
changes then fall out fairly naturally.
Fixes#324.

The documentation says:
> If `$XDG_CONFIG_HOME` is not set or is empty, then
> `$HOME/.config/git/ignore` is used instead.
This is the expected behavior, but the code looked at ~/git/ignore
instead.
Currently, Rust's standard library will yield an error if one tries to
write invalid UTF-8 to a Windows console. This is problematic for
ripgrep when it tries to print matched lines that contain invalid UTF-8.
We work around this by modifying the `termcolor` library to lossily
decode UTF-8 before sending it to `std::io::Stdout`. This may result in
some Unicode replacement chars being shown in the output, but this is
strictly better than erroring or not showing anything at all.
Fixes#318.
