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
This was a subtle bug, but the big picture was that the smart case
information wasn't being carried through to the literal extraction in
some cases. When this happened, it was possible to get back an incomplete
set of literals, which would therefore miss some valid matches.
The fix to this is to actually parse the regex and determine whether
smart case applies before doing anything else. It's a little extra work,
but parsing is pretty fast.
Fixes#199
This adds a new walk type in the `ignore` crate, `WalkParallel`, which
provides a way for recursively iterating over a set of paths in parallel
while respecting various ignore rules.
The API is a bit strange, as a closure producing a closure isn't
something one often sees, but it does seem to work well.
This also allowed us to simplify much of the worker logic in ripgrep
proper, where MultiWorker is now gone.
The name has_ignores is not descriptive in my opinion. I think
has_any_ignore_options more clearly states this method's purpose. I also
considered simply IgnoreOptions::any though I went with the more verbose
option.
This was probably a transcription error when moving the ignore matcher
code out of ripgrep core. Specifically, the override glob matcher should
not ignore directories if they don't match.
Fixes#206
