Subject: [PATCH] Build syntect with onig instead of fancy-regex
|
|
|
|
Replace pure Rust fancy-regex with onig linked against system-provided
|
|
oniguruma library.
|
|
|
|
From the syntect's Readme (https://github.com/trishume/syntect):
|
|
> The advantage of fancy-regex is that it does not require the onig crate
|
|
> which requires building and linking the Oniguruma C library. Many users
|
|
> experience difficulty building the onig crate, especially on Windows
|
|
> and Webassembly.
|
|
|
|
> As far as our tests can tell this new engine is just as correct, but it
|
|
> hasn't been tested as extensively in production. It also currently seems
|
|
> to be about half the speed of the default Oniguruma engine
|
|
|
|
Oniguruma engine is faster than the fancy-regex engine and the syntect
|
|
project chose the latter as the default only to avoid difficulties with
|
|
linking Oniguruma (C library) on some platforms. That's not our case.
|
|
|
|
Moreover, gitui built with Oniguruma instead of fancy-regex is smaller
|
|
(2.9 MiB x 3.8 MiB). libonig.so is 0.5 MiB, so we saved 0.4 MiB or 0.9 MiB,
|
|
if libonig.so is already installed for some other package.
