In a prior commit, we fixed a performance problem with the -w flag by doing a little extra work to extract literals. It turns out that using literals in this case when the -w flag is NOT used results in a performance regression. The reasoning is that we end up using a "fast" regex as a prefilter when the regex engine itself uses its own equivalent prefilter, so ripgrep ends up redoing a fair amount of work. Instead, we only do this extra work when we know the -w flag is enabled. |

grep-regex
The grep-regex crate provides an implementation of the Matcher trait from
the grep-matcher crate. This implementation permits Rust's regex engine to
be used in the grep crate for fast line oriented searching.
Dual-licensed under MIT or the UNLICENSE.
Documentation
NOTE: You probably don't want to use this crate directly. Instead, you
should prefer the facade defined in the
grep
crate.
Usage
Add this to your Cargo.toml:
[dependencies]
grep-regex = "0.1"
and this to your crate root:
extern crate grep_regex;
