Custom hashifying

[rejeep]

Hi,

I read about the decision to remove hashifying in #108. It has been bugging me for quite some time that it was removed from projectile. Without hashifying, projectile's find file functionality is almost useless to me.

This pull request contains two commits:

• rejeep@92de619 - Caching bug
• rejeep@99d9e6e - Allow to specify custom completion function

The second commit allows you to specify whatever completion function you want. Since I really don't want files relative to the root, but rather just the file name, I created this function. I'm not sure if you want this function as a part of projectile, if you do, tell me and I'll add it. Otherwise people that find it useful can simply add it to their Emacs config.

Note that I just created this hence has not been tested that well.

I'm ok with the change. Please, update the documentation accordingly to reflect this change. You can also list your completion function there as an example of a custom completion function.

[rejeep]

Do you mean that I should link to my gist from the doc and show an example of how to use it?

Do you have any other documentation than the README?

[bbatsov]

Yep for the gist. Documentation == README.

[rejeep]

@bbatsov Added some docs.

[bbatsov]

Looks good! Thanks!

P.S. It seems that your previous PR has broken the travis build:

$ make deps
make: *** No rule to make target `deps'.  Stop.

@bbatsov Looks like the branch wasn't rebased

[rejeep]

Also, It looks like I missed this: https://github.com/bbatsov/projectile/blob/master/.travis.yml#L7 Should be:

- make elpa

[bbatsov]

Will you prepare another PR?

[rejeep]

For the whole thing? Then it would be my name in the merge message (if that's ok with you).

[bbatsov]

Sure.

See #138

@rejeep your function won't work with 'alien' indexing method enabled, as there's no cache in this case. This one just does matches against original choices array and will work in any case https://gist.github.com/pashky/6522273

@pashky Nice catch, thanks! I updated my Gist!
