Stumpwm is a window manager written entirely in Common Lisp. It attempts to be highly customizable while relying entirely on the keyboard for input. You will not find buttons, icons, title bars, tool bars, or any of the other conventional GUI widgets.

These design decisions reflect the growing popularity of productive, customizable lisp based systems.

Stumpwm is a "everything-and-the-kitchen-sink WM" or "the emacs of WMs."

StumpWM:Windows::Emacs:Text

• StumpWM is
  • Hackable
  • A tileable window manager
  • Includes support for floats
  • Written in Common Lisp
  • Compatible with many lisp distributions
  • A Superior window managing experience
• StumpWM is not
  • Minimalist
  • Narrow Scope
  • Configured by editing the source directly
  • A full blown desktop environment

If you want a minimalist tiling window manager, then StumpWM is not what you're looking for. The code base is ~15k sloc, the binaries produced are ~60mb.

StumpWM manages windows the way emacs manages buffers, or the way screen manages terminals. If you want a flexible, customizable, hackable desktop experience, look no further.

• a common lisp distribution. sbcl, clisp, ccl and ecl all work (ecl must have been built with clx support, must use version >= 13.5.1 see here for discussion).
• quicklisp (for obtaining the following dependencies, not needed if you use your distribution's package manager.)
• clx
• cl-ppcre
• cl-xembed

The recommended way to install the dependencies is using Quicklisp. Follow the instructions at http://www.quicklisp.org/ to install it. In short:

$ curl -O http://beta.quicklisp.org/quicklisp.lisp

$ sbcl --load quicklisp.lisp

Or insert your favorite lisp distribution (clisp, ccl or ecl). Then at the REPL:

(quicklisp-quickstart:install)

Make sure you have added it to your lisp init file using:

 (ql:add-to-init-file)

Then, in a repl:

 (ql:quickload "clx")
 (ql:quickload "cl-ppcre")

Building stumpwm from git requires that you build the configure script:

 autoconf

If there's already a configure script then just run it.

 ./configure

By default stumpwm elects sbcl. If you have multiple lisps installed, you can explicitly select clisp, ccl, or ecl like so:

 ./configure --with-lisp=clisp

If your lisps are in strange places you may need to tell the script where to find them:

 ./configure --with-sbcl=/home/sabetts/opt/bin/sbcl
 ./configure --with-clisp=/usr/local/downstairs/to/the/left/clisp

Now build it:

 make

If all goes well, you should have a stumpwm binary now. You can run the binary from where it is or install it, along with the .info documentation, with:

 make install

Now that you have a binary, call it from your ~/.xinitrc file:

 echo /path/to/stumpwm >> ~/.xinitrc
 startx

Hopefully that will put you in X running stumpwm! See StartUp on the wiki for more examples.

For stumpwm to work as intended with multiple monitors setups the xdpyinfo utility is needed.

Pull requests are always welcome! Here are some guidelines to ensure that your contribution gets merged in a timely manner:

• Do's
  • Preserve comments or docstrings explaining what code does, and update them if your patch changes them in a significant way
  • Try to follow an "80 column rule." The current code base does not follow this all the time, so don't use it as an example
  • Use lisp idioms
  • If you are working on a major change to the internals, keep us informed on stumpwm-devel! Also, it will probably help if the changes are made and the incrementally applied to the codebase in order to avoid introducing show-stopping bugs.
• Do not's
  • Include emacs local variables
  • Change whitespace
  • Write lots of code without supporting comments/documentation
  • Delete comments or docstrings (yes this is a duplicate of above!)
  • Export symbols from packages that aren't widely useful (many times a little more thought will reveal how to implement your internal change without having to export/break encapsulation)
  • Make stylistic changes that suit your coding style/way of thinking

Our wiki has fallen into disarray/disrepair, but it is shaping up. If you aren't a lisp hacker, you can contribute in the form of documenting and organizing the wiki. There's a lot of information floating around, if you find it where you didn't expect it, move or link to it in a more logical place.

On 64bit platforms, CCL reserves a "very large" amount of virtual memory. If this bothers you for some reason, you can pass the -R or --heap-reserve option to the binary in your ~/.xinitrc file. See http://ccl.clozure.com/manual/chapter15.1.html for an explanation.

There's a texinfo manual, stumpwm.texi. The build scripts generate an info file you can read in emacs or with the `info' program. The manual for the latest release is available to read online at:
