This is to prep for the next release. I don't know if the requirement
will actually be for Rust 1.88, but it is intended to support the latest
version of stable Rust.
This feature causes nothing but problems and is frequently broken. The
only optimization it was enabling were SIMD optimizations for
transcoding. In particular, for UTF-16 transcoding. This is performed by
the [`encoding_rs`](https://github.com/hsivonen/encoding_rs) crate,
which specifically uses unstable portable SIMD APIs instead of the
stable non-portable SIMD APIs.
SIMD optimizations that apply to search have long been making use of
stable APIs, and are automatically enabled when your target supports
them. This is, IMO, the correct user experience and one that
`encoding_rs` refuses to support. I'm done dealing with it, so
transcoding will only use scalar code until the SIMD optimizations in
`encoding_rs` work on stable. (This doesn't mean that `encoding_rs` has
to change. This could also be fixed by stabilizing `std::simd`.)
Fixes#2748
I definitely wonder whether I should just drop 'sudo' from the install
instructions and just rely on the user to "know" to do it. But some
commands legitimately do not require 'sudo', so there are actual
differences. Overall, this feels clearer to me but reasonable people can
disagree.
We probably don't need to mention Buster specifically nor Debian
unstable since ripgrep has been in Debian for a while now.
But we can't just get rid of the `deb` file either, because Debian might
package a very old version.
Fixes#2531
I'm not sure about putting this in such a prominent spot, and it does
bloat the introductory paragraph a bit, but it seems like an important
special case.
This also updates the corpora used, so previous times (and counts) are
not comparable.
We also remove some tools, likt pt, sift and ucg, since they appear to
be no longer maintained. ag isn't really maintained either, but it still
has significant mind share, so we retain a benchmark for it.
We also upgrade ack to version 3, and remove the clarification on how
`-w` is implemented.
We also add `git grep -P` (uses PCRE2) which appears to be much faster
than `git grep -E`.
Finally, we add ugrep which is a new up and comer in this space.
Fixes#1474
This permits switching between the different regex engine modes that
ripgrep supports. The purpose of this flag is to make it easier to
extend ripgrep with additional regex engines.
Closes#1488, Closes#1502
