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 (when feasible). For instance -
finding project files has a portable implementation written in pure
Emacs Lisp without the use of GNU
find (but for performance sake an
indexing mechanism backed by external commands exists as well).
Projectile tries to be practical - portability is great, but if some external tools could speed up some task substantially and the tools are available, Projectile will leverage them.
This library provides easy project management and navigation. The concept of a
project is pretty basic - just a folder containing some special file (e.g. a VCS
marker or a project descriptor file like
will auto-detect pretty much every popular project type out of the box
and you can easily extend it with additional project types.
Here are some of Projectile's features:
- jump to a file in project
- jump to a project buffer
- jump to a test in project
- toggle between files with same names but different extensions (e.g.
- toggle between code and its test (e.g.
- jump to recently visited files in the project
- switch between projects you have worked on
- kill (close) all project buffers
- replace in project
- grep (search) in project
- run shell commands in a project (e.g.
- support for multiple minibuffer completion/selection libraries (
helmand the default completion system)
I've been developing Projectile for a decade now. While it's a fun project to work on, it still requires a lot of time and energy to maintain.
Projectile in Action
Here's a glimpse of Projectile in action (using
In this short demo you can see:
- finding files in a project
- switching between implementation and test
- switching between projects
The instructions that follow are meant to get you from zero to a running Projectile setup in a minute. Visit the online documentation for (way) more details.
package.el is the built-in package manager in Emacs.
You can install Projectile with the following command:
Alternatively, users of Debian 9 or later or Ubuntu 16.04 or later may
apt-get install elpa-projectile.
Finally add this to your Emacs config:
(projectile-mode +1) ;; Recommended keymap prefix on macOS (define-key projectile-mode-map (kbd "s-p") 'projectile-command-map) ;; Recommended keymap prefix on Windows/Linux (define-key projectile-mode-map (kbd "C-c p") 'projectile-command-map)
Those keymap prefixes are just a suggestion. Feel free to put there whatever works best for you.
projectile-mode, open a file in one of your projects and type a command such as C-c p f.
See the online documentation for more details.
- Some operations like search (grep) depend (presently) on external
utilities such as
- Commands depending on external utilities might misbehave on the
- Using Projectile over TRAMP might be slow in certain cases.
- Some commands might misbehave on complex project setups (e.g. a git project with submodules)
- Projectile was mostly tested on Unix OS-es (e.g. GNU/Linux and macOS), so some functionality might not work well on Windows
Check out the project's issue list a list of unresolved issues. By the way - feel free to fix any of them and send me a pull request. :-)
