dewm - a window manager written with literate programming
dewm is a pure Go autotiling window manager. It's intended to make the text
editor de feel more similar to acme when windows
are spawned with the p9p plumber, with the window management handled at a window
manager level, rather than integrated into the text editor. (If you're unfamiliar
with acme, it's a text editor written by Rob Pike for Plan 9 after he got drunk
one night and forgot that he wrote "cat -v considered harmful.")
dewm is written in a literate programming
style, in the hopes that it can inspire anyone else who's ever wanted to write
their own window manager that they can learn enough to do it. I knew next to
nothing about the X11 protocol or ICCCM conventions when I started this (and
still don't), so if I got anything wrong please feel free to either send a pull
request or email me so I can correct it. I don't want to misinform anyone who
reads the markdown source in the src/ directory.
Basics
dewm arranges the screen into columns, and divides columns up between windows
that are in that column. Windows always spawn in the first empty column, or the
end of the last column if there are no empty columns. (If no columns exist, the
first one is created automatically.)
By default, all columns are equally sized, and each window in any given column
is equally sized, but they can be resized dynamically (see keybindings below).
Keybindings
These keybindings are currently hardcoded, but may one day be configurable.
Window Management
Alt-H/Alt-Lmove the current window left or right 1 column.Alt-J/Alt-Kmove the current window up or down 1 window in current columnCtrl-Alt-Up/Downincrease/decrease the size of the current window. Other
windows will be dynamically resized to make sure the column still takes the
whole height of the screen.)Ctrl-Alt-Left/Rightincrease/decrease the size of the column with the
currently active window. (Other columns will be dynamically resized to
make up for it.)Ctrl-Alt-Entertoggle whether or not the current window is maximized.Ctrl-Shift-Ncreate a new columnCtrl-Shift-Ddelete any empty columns

Screenshots
This is what dewm looks like with two windows in two columns:
And this is it looks like if, after browsing a bit, you threw an xterm into
the mix.
Installation
The generated go files are included in this repo, so that you can install dewm
with the standard go get tool (go get github.com/driusan/dewm)
You should then be able to add:
dewm
to the end of your .xinitrc or .xsession file (assuming $GOBIN is in your
path, otherwise you'll have to include the full the path to the executable,
wherever go get compiled it to.)
