License GPL 3 MELPA MELPA Stable Build Status


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 pom.xml or Gemfile). Projectile 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. .h <-> .c/.cpp, Gemfile <-> Gemfile.lock)
  • toggle between code and its test (e.g. main.service.js <-> main.service.spec.js)
  • 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. make, lein)
  • support for multiple minibuffer completion/selection libraries (ido, ivy, helm and the default completion system)

Patreon Paypal

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.

You can support my work on Projectile via PayPal, Patreon and GitHub Sponsors.

Projectile in Action

Here's a glimpse of Projectile in action (using ivy):

Projectile Demo

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.

Projectile is available on the two major package.el community maintained repos - MELPA Stable and MELPA.

You can install Projectile with the following command:

M-x package-install [RET] projectile [RET]

Alternatively, users of Debian 9 or later or Ubuntu 16.04 or later may simply 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.

Basic Usage

Enable 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 find.
  • Commands depending on external utilities might misbehave on the fish shell.
  • 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

Known issues

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. :-)
