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
This is for consistency with the short and long flags given in other
bullet points. I originally assumed there was no long flag for `-P`
because none was given here.
PR #1254
This feature solves a major reason I was skeptical of using ripgrep, so
I think it’s good to mention it in the section about why one should use
it.
I use backreferences a lot, so I had previously thought that ripgrep
would provide no speed advantage over ag, since I would always have
`-P` enabled. But when I saw `--auto-hybrid-regex` in the 11.0.0
changelog, I learned that ripgrep can use it to speed up simple queries
while still allowing me to write backreferences.
PR #1253
This brings in an updated `encoding_rs` crate that uses `packed_simd`,
which compiles on the latest nightly. Compilation times do appear to be
impacted significantly though.
Fixes#1175 (again)
Add a note about it to the README.
Also, remove mention of the avx-accel feature since it no longer exists.
(bytecount now uses runtime detection to enable SIMD support.)
Fixes#1175
This also updates some code to make use of our more liberal versioning
requirement, including the use of crossbeam-channel instead of the MsQueue
from the older an unmaintained crossbeam 0.3. This does regrettably add
a sizable number of dependencies, however, compile times seem mostly
unaffected.
Closes#1019
This commit does the work to delete the old `grep` crate and effectively
rewrite most of ripgrep core to use the new libripgrep crates. The new
`grep` crate is now a facade that collects the various crates that make
up libripgrep.
The most complex part of ripgrep core is now arguably the translation
between command line parameters and the library options, which is
ultimately where we want to be.
The preprocessor flag accepts a command program and executes this
program for every input file that is searched. Instead of searching the
file directly, ripgrep will instead search the stdout contents of the
program.
Closes#978, Closes#981
1.23.0 is the first Rust release of 2018 and is around half a year old,
which seems old enough to move to. This also lets us bring in encoding_rs
0.8, which includes performance optimizations.
This causes SIMD to kick in automatically when compiling with stable
Rust 1.27+.
We also update the README to describe the current state of things.
Thanks to @hartley for pointing this out:

Snap has caused a number of nonsensical bug reports, and not even the
`--classic` flag seems capable of fixing them. Therefore, remove snap
from the README and put in a special line in the ISSUE_TEMPLATE about
snap.
FIxes#902
It would be nicer to switch to the `ripgrep` snap package, but
apparently it is configured to install with a binary name `ripgrep.rg`
instead of just `rg`. *sigh*
