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
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
projectile.el somewhere in your
load-path. I favour the
(add-to-list 'load-path "~/emacs.d/vendor")
You can enable projectile globally like this:
(require 'projectile) (projectile-global-mode) ;; to enable in all buffers
To enable projectile only in select modes:
(add-hook 'ruby-mode-hook #'(lambda () (projectile-mode)))
If you'd like to enable project files caching (useful in large projects where indexing the project's file can take a while) add this as well:
(setq projectile-enable-caching t)
If you're an Emacs 24 user or you have a recent version of package.el you can install projectile from the Marmalade repository.
Projectile is naturally part of the Emacs Prelude. If you're a Prelude user - projectile is already properly configured and ready for action.
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 can be integrated with
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
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. :-)

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.
