Projectile is a project interaction library for Emacs. Its goal is to provide a nice set of features operating on a project level without introducing external dependencies. For instance - finding project files is done in pure elisp without the use of GNU find.
This library provides easy project management and navigation. The
concept of a project is pretty basic - just a folder containing
special file. Currently git
, mercurial
and bazaar
repos are
considered projects by default. If you want to mark a folder
manually as a project just create an empty .projectile
file in
it. Some of projectile's features:
- jump to a file in project
- jump to a project buffer
- multi-occur in project buffers
- grep in project
- regenerate project etags
- run make in a project with a single key chord
Just drop projectile.el
and s.el
somewhere in your load-path
. I favour the folder
~/.emacs.d/vendor
:
(add-to-list 'load-path "~/emacs.d/vendor")
(require 'projectile)
If you're an Emacs 24 user or you have a recent version of package.el
you can install projectile from the
Marmalade repository.
If you're an Emacs 24 user or you have a recent version of package.el
you can install projectile from the
MELPA repository. The version of
projectile there will always be up-to-date, but it might be unstable
(albeit rarely).
Projectile is naturally part of the Emacs Prelude. If you're a Prelude user - projectile is already properly configured and ready for action.
You can enable projectile globally like this:
(projectile-global-mode)
To enable projectile only in select modes:
(add-hook 'ruby-mode-hook 'projectile-on)
Since indexing a big project is not exactly quick in Emacs Lisp, projectile caches the project's files automatically. This means you'll have to invalidate the cache from time to time when new files are added to the project. If you're working on a smaller project and you don't mind the reindexing delay you may disable the cache:
(setq projectile-enable-caching nil)
At this point you can try out a projectile command such as C-c p f
(projectile-find-file
).
If you want Projectile to be usable in every directory (even without the presence of project file):
(setq projectile-require-project-file nil)
This might not be a great idea if you start projectile in your home folder for instance :-)
If you don't like ido you can use regular completion as well:
(setq projectile-completion-system 'default)
You might want to combine default completion with icomplete-mode
for optimum results.
Here's a list of the interactive Emacs Lisp functions, provided by projectile:
projectile-find-file
(C-c p f)projectile-grep
(C-c p g)projectile-switch-to-buffer
(C-c p b)projectile-multi-occur
(C-c p o)projectile-replace
(C-c p r)projectile-invalidate-cache
(C-c p i)projectile-regenerate-tags
(C-c p t)projectile-kill-buffers
(C-c p k)projectile-dired
(C-c p d)projectile-recentf
(C-c p e)projectile-ack
(C-c p a)projectile-compile-project
(C-c p l)projectile-test-project
(C-c p p)
If you'd like to instruct Projectile to ignore certain files in a
project, when indexing it you can do so in the .projectile
file. Here's an example for a typical Rails application:
log
tmp
vendor
public/uploads
Projectile can be integrated with
Helm via
helm-c-source-projectile
source (available in helm-projectile.el
). There is also an example function
for calling Helm with the Projectile file source. You can call it like
this:
M-x helm-projectile
or even better - bind it to a keybinding like this:
(global-set-key (kbd "C-c h") 'helm-projectile)
Obviously you need to have Helm installed for this to work :-)
- Traversing the project directory programmatically (instead of using something like GNU find) is not very fast. On the other hand - it's portable. Unlike find-file-in-project, projectile's jump-to-file will work on any OS.
- To compensate for the lack of speed - a cache can be created when a project is traversed. That cache is not automatically updated (presently) so you might want to invalidate it manually from time to time (or disable it completely for small projects).
- Some operations like find/replace depend (presently) on external utilities such as find and perl.

Check out the project's issue list a list of unresolved issues. By the way - feel free to fix any of them and sent me a pull request. :-)
Here's a list of all the people who have contributed to the development of Projectile.
Contribution is always welcome!
Install carton if you haven't already, then:
$ cd /path/to/projectile
$ carton
Run all tests with:
$ make
Bug reports and suggestions for improvements are always welcome. github pull requests are even better! :-)
Together we can create the ultimate project management tool for Emacs.
