Projectile Goes Turbo

| Comments

For a while one of the biggest complaints people had about Projectile was that the alien indexing wasn’t fast enough (especially on big projects). The reason for the (relatively) bad performance was pretty simple - even though Projectile would normally obtain the list of project files pretty fast (e.g. by using git ls-files) it always did some post-processing of the results (e.g. filtering, sorting, etc), which is a very slow operation in Elisp on a big dataset.

Today I’ve added a new indexing method that simply dispenses with all of the post-processing and gives you the raw power you always craved for. It’s called turbo-alien (yeah, yeah - naming is hard!) and it’s going to be the default indexing method going forward (starting with Projectile 1.1 which should be released pretty soon).

You can read a bit more about it in Projectile’s manual.

If you find yourself missing Projectile’s old behaviour just add the following to your config:

1
(setq projectile-indexing-method 'alien)

The old tried and true alien method is still around, it’s just no longer the default.

P.S. I encourage all of you to help out with some of the open tickets marked with “Help Wanted” or “Good First Issue” here. I’m trying to clean-up shop after a long period of stagnation and I can certainly use some help! :-)

P.P.S. The recent 1.0 release was just a precursor to some bigger changes I had planned to do for quite a while. Stay tuned for more updates!
