Subject: [bug#39258] [PATCH 2/4] ui: Use string matching with literal search strings.
Date: Tue, 09 Jun 2020 10:33:04 +0200	[thread overview]
Message-ID: <87y2owmyf3.fsf@gnu.org> (raw)
In-Reply-To: <20200601000030.7443-3-arunisaac@systemreboot.net> (Arun Isaac's message of "Mon, 1 Jun 2020 05:30:28 +0530")

Arun Isaac <arunisaac@systemreboot.net> skribis:

> * guix/scripts/package.scm (process-query): Make search query a regexp only if
> it is not a literal search string.
> * guix/ui.scm (relevance): Use string matching with literal search strings and
> regexp matching with regexp search strings.

How does this affect performance?

I would expect the regexp engine in libc to do something similar
internally, so I wonder if the extra work in Scheme pays off.
