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).
In practical terms the fact that Projectile can index the files in
a project without shelling out to
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.
Projectile provides easy project management and navigation. The
concept of a project is pretty basic - just a folder containing
special file. Currently most VCS repos (e.g.
are considered projects by default, as are directories containing
build tools (e.g.
leiningen, etc) or framework markers
(e.g. Ruby on Rails). If you want to mark a folder manually as a
project just create an empty
.projectile file in it.

Here are some of Projectile’s features in no particular order:
jump to a file in project
jump to files at point in project
jump to a directory in project
jump to a file in a directory
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 all project buffers
replace in project
multi-occur in project buffers
grep in project
regenerate project etags or gtags (requires ggtags).
visit project in dired
run make in a project with a single key chord
browse dirty version controlled projects
support for multiple minibuffer completion/selection libraries (
helmand the default completion system)
Here’s a glimpse of Projectile in action (using
ivy for minibuffer completion):

I’ve started working on Projectile in 2011 and I’ve been maintaining it ever since. It slowly grew from an obscure project with a single user to one of the most popular packages in the realm of Emacs. It’s a fun project, but it also requires a lot of work.
You can support my work on Projectile (and all my other Emacs package) via one of the following platforms:

|A bit of trivia for you - Projectile was my very first open-source project and it has a very special place in my heart!|
So, what to do next? While you can peruse the documentation in whatever way you’d like, here are a few recommendations:
