Leiningen is for automating Clojure projects without setting your hair on fire.

## Installation
|
2009-11-02 07:02:16 +00:00
|
|

If your preferred
|
|
|
|
[package manager](https://github.com/technomancy/leiningen/wiki/Packaging)
|
2017-10-18 17:19:57 +00:00
|
|
|
offers a recent version of Leiningen, try that first as long as it has version 2.x.
|

Leiningen installs itself on the first run of the `lein` shell script; there is no
|
|
|
|
separate install script. Follow these instructions to install Leiningen manually:
|
2010-03-13 05:04:11 +00:00
|
|
|
|
2017-10-18 17:19:57 +00:00
|
|
|
1. Make sure you have Java installed; version 8 is recommended at this time.
|
2014-07-19 22:52:50 +00:00
|
|
|
2. [Download the `lein` script from the `stable` branch](https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lein)
|
|
|
|
of this project.
|
2013-03-22 16:26:59 +00:00
|
|
|
3. Place it on your `$PATH`. (`~/bin` is a good choice if it is on your path.)
|
2017-04-26 15:07:55 +00:00
|
|
|
4. Set it to be executable. (`chmod +x ~/bin/lein`)
|
2014-07-19 22:52:50 +00:00
|
|
|
5. Run it.
|

### Windows
|
2013-06-06 12:02:05 +00:00
|
|
|
|
2013-07-26 20:01:56 +00:00
|
|
|
There is
|
|
|
|
[an installer](http://leiningen-win-installer.djpowell.net/) which
|
2013-06-13 00:08:51 +00:00
|
|
|
will handle downloading and placing Leiningen and its dependencies.
|
2013-06-06 12:02:05 +00:00

The manual method of putting
|
2014-05-05 20:54:54 +00:00
|
|
|
[the batch file](https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lein.bat).
|
2013-07-26 20:01:56 +00:00
|
|
|
on your `PATH` and running `lein self-install` should still work for
|
|
|
|
most users. If you have [Cygwin](http://www.cygwin.com/) you should be
|
|
|
|
able to use the shell script above rather than the batch file.

2016-02-24 15:43:45 +00:00
|
|
|
N.B.: Avoid using a LEIN_JAR environment variable.
|
|
|
|
If you have one instance of Leiningen on your PATH as well as a LEIN_JAR
|
|
|
|
pointing to a different instance, there is a known problem where `lein -v` and
|
2017-08-04 12:53:42 +00:00
|
|
|
`lein upgrade` will refer to the first instance, while usage of Leiningen, such
|
2016-02-24 15:43:45 +00:00
|
|
|
as `lein new foobar`, will refer to the latter.

## Basic Usage
|
2009-10-31 21:35:25 +00:00

The
|
2013-01-20 04:39:43 +00:00
|
|
|
[tutorial](https://github.com/technomancy/leiningen/blob/stable/doc/TUTORIAL.md)
|
2010-06-19 03:56:36 +00:00
|
|
|
has a detailed walk-through of the steps involved in creating a new
|
|
|
|
project, but here are the commonly-used tasks:
|
|
|
|
|
2012-04-12 17:12:05 +00:00
|
|
|
$ lein new [TEMPLATE] NAME # generate a new project skeleton
|
2010-06-05 20:26:52 +00:00
|
|
|
|
2009-11-29 22:20:09 +00:00
|
|
|
$ lein test [TESTS] # run the tests in the TESTS namespaces, or all tests
|
2009-11-02 06:47:21 +00:00
|
|
|
|
2012-02-08 05:00:02 +00:00
|
|
|
$ lein repl # launch an interactive REPL session
|
2009-10-31 21:35:25 +00:00
|
|
|
|
2012-05-25 01:26:46 +00:00
|
|
|
$ lein run -m my.namespace # run the -main function of a namespace
|
2009-11-09 06:09:39 +00:00
|
|
|
|
2012-05-25 01:26:46 +00:00
|
|
|
$ lein uberjar # package the project and dependencies as standalone jar
|
2011-10-21 19:45:53 +00:00
|
|
|
|
2014-09-09 23:25:46 +00:00
|
|
|
$ lein deploy clojars # publish the project to Clojars as a library
|
|
|
|
|
2011-10-19 23:24:30 +00:00
|
|
|
Use `lein help` to see a complete list. `lein help $TASK` shows the
|
2012-01-13 00:10:32 +00:00
|
|
|
usage for a specific task.
|
2009-11-20 01:50:33 +00:00
|
|
|
|
2012-06-10 04:48:32 +00:00
|
|
|
You can also chain tasks together in a single command by using the
|
|
|
|
`do` task with comma-separated tasks:
|
2010-08-18 05:21:53 +00:00
|
|
|
|
2012-06-10 04:48:32 +00:00
|
|
|
$ lein do clean, test foo.test-core, jar
|
2010-08-17 05:05:24 +00:00
|
|
|
|
2010-08-18 05:21:53 +00:00
|
|
|
Most tasks need to be run from somewhere inside a project directory to
|
2012-04-12 17:12:05 +00:00
|
|
|
work, but some (`new`, `help`, `search`, `version`, and `repl`) may
|
|
|
|
run from anywhere.
|
2010-08-17 05:05:24 +00:00

|
## Configuration
|
|
|
|
|
2011-10-19 23:24:30 +00:00
|
|
|
The `project.clj` file in the project root should look like this:
|
2011-08-17 20:13:17 +00:00
|
|
|
|
2012-01-13 01:10:35 +00:00
|
|
|
```clj
|
2011-08-17 20:13:17 +00:00
|
|
|
(defproject myproject "0.5.0-SNAPSHOT"
|
|
|
|
:description "A project for doing things."
|
2013-01-03 06:32:07 +00:00
|
|
|
:license "Eclipse Public License 1.0"
|
2011-08-17 20:13:17 +00:00
|
|
|
:url "http://github.com/technomancy/myproject"
|
2016-01-21 10:08:58 +00:00
|
|
|
:dependencies [[org.clojure/clojure "1.8.0"]]
|
2014-09-09 23:25:46 +00:00
|
|
|
:plugins [[lein-tar "3.2.0"]])
|
2011-08-18 01:00:12 +00:00
|
|
|
```
|
2009-10-31 21:35:25 +00:00
|
|
|
|
2012-05-10 02:22:04 +00:00
|
|
|
The `lein new` task generates a project skeleton with an appropriate
|
|
|
|
starting point from which you can work. See the
|
2013-01-20 04:39:43 +00:00
|
|
|
[sample.project.clj](https://github.com/technomancy/leiningen/blob/stable/sample.project.clj)
|
2012-05-10 02:22:04 +00:00
|
|
|
file (also available via `lein help sample`) for a detailed listing of
|
|
|
|
configuration options.

|
|
|
|
2012-05-25 01:26:46 +00:00
|
|
|
The `project.clj` file can be customized further with the use of

Leiningen supports plugins which may introduce new tasks. See
|
2012-01-13 01:10:35 +00:00
|
|
|
[the plugins wiki page](https://github.com/technomancy/leiningen/wiki/Plugins)
|
|
|
|
for a full list. If a plugin is needed for successful test or build
|
|
|
|
runs, (such as `lein-tar`) then it should be added to `:plugins` in
|
2011-10-21 21:36:40 +00:00
|
|
|
project.clj, but if it's for your own convenience (such as
|
2014-09-09 23:25:46 +00:00
|
|
|
`lein-pprint`) then it should be added to the `:plugins` list in the
|
2012-12-21 16:27:03 +00:00
|
|
|
`:user` profile in `~/.lein/profiles.clj`. See the
|
2013-01-20 04:39:43 +00:00
|
|
|
[profiles guide](https://github.com/technomancy/leiningen/blob/stable/doc/PROFILES.md)
|
2012-12-21 16:27:03 +00:00
|
|
|
for details on how to add to your `:user` profile. The
