Hi,
I attached a small patch to extend xref-search-program-alist and
xref-xref-search-program with support for ugrep[1].
Is it something that can be of any interest?

Sure.
Does ugrep show better performance in this use case than grep on your
machine?

0.026032s (0.022015s in 1 GCs) implies the total runtime sans GC
takes 0.026 - 0.022 = 0.004, which is pretty much the same as what you
measured for ugrep (0.0039). The the choice of search program is
unlikely to affect the GC time. It probably occurred randomly.
You might want to try doing a search in a larger project, for a
relatively unique string (which has less than 100 matches, say). Then
you can see the effect of search program's performance.

I tried `(benchmark-run (project-find-regexp "torvalds"))` in the Linux kernel code.
With grep: (3.628388951 6 0.3137041489999959)
With ugrep: (2.664314312 6 0.31696058299999663)

This is pretty good.
Did you run them a bunch of times? All subsequent searches after the
first one are usually faster because of "warm" filesystem cache.

This what I get:
3 subsequent tries with grep:

3 subsequent tries with ugrep:
(2.838539952 6 0.33570421699999997)

Hi Dmitry,
is there something more you need me to do on this?

Both code and testing look good, thanks.
I've pushed the change in 9468ab2570.
Please take a look at the commit message, though. It would be helpful if
your patches use the required format right away.

Thanks, and sorry about the typo that you had to fix.

Thanks for the tip, I will do. I thought I had done it this time but I see now
that I missed something.
