basedwm v0.1.2
basedwm 
Minimalistic X window manager in LiveScript, with an infinite panning desktop. Controlled by named pipe. Emits focus events and window positions on a socket.
Install
You only need Node.js (or io.js) to run the basic WM.
sudo npm i -g basedwmThen add exec basedwm to your ~/.xinitrc, commenting out any existing WM.
However, note that basedwm alone doesn't provide any keyboard or pointer controls or window decorations. Instead, it takes control input from a named pipe and logs focus events and window positions out to another named pipe. This way you can easily switch out what programs you use to control it or to render window decorations.
Keyboard controls
Recommendations
To bind commands to keyboard controls, I recommend sxhkd. A suitable
example config is in example/basedwm.sxhkdrc.
Details
Basedwm is controlled through a named pipe, by default at
/tmp/basedwm:0-cmd.fifo (where the :0 is the contents of the $DISPLAY
env variable). The program basedc is provided for convenience; it just
echoes its arguments into that pipe.
Some commands are stateless and run immediately:
| name | description |
|---|---|
| exit | terminates the program |
| raise | raises the currently focused window |
| pointer-raise | raises window under pointer |
| move x y | moves the currently focused window by the given amount |
| move-all x y | moves all windows, effectively panning the desktop |
| resize x y | resizes the currently focused window by the given amount |
| destroy | closes the currently focused window (polite suggestion) |
| kill | kills the currently focused window (force close) |
So basedc move-all 50 -50 to move all windows 50px right and 50px up.
The stateful ones are intended for pointer interaction:
| name | description |
|---|---|
| pointer-move x y | moves focused window with pointer |
| pointer-resize x y | resizes focused window with the pointer |
| pointer-move-all x y | pans desktop with pointer |
| reset | resets pointer drag state |
Remember to send a reset once each drag is done! This tells basedwm that the
next pointer command will be a separate action.
Window decorations
Recommendations
Hudkit was written for this. I'll get around to uploading my setup
eventually, but the basic idea is to create a Node server that net.connects
to the WM state socket, dumps the events into a websocket and serves up a page
that uses D3 to render borders and a minimap. Screenshot here.
Details
Basedwm outputs window positions on a socket in /tmp/wmstate.sock, as
newline-delimited JSON objects. Every object has a property id with
the window's ID, and a property action representing the event type.
The possible actions and their additional properties are:
| action | description | additional properties |
|---|---|---|
| focus | window gained focus | none |
| destroy | window was destroyed | none |
| existing-add | initial window position | x, y, width, height |
| add | window was added | x, y, width, height |
| move | window was moved | x, y |
| resize | window was resized | width, height |
existing-add-events are only sent immediately after connecting. This lets
any consuming program initialise its copy of the window positions.
The x and y properties indicate the absolute coordinates of the window's
top-left corner, relative to the screen's top-left corner. The width and
height properties indicate the absolute dimensions of the window.
You can easily survey the output using socat UNIX:/tmp/wmstate.sock -.
Bugs
Yes.
Inspirations & thankyous
Intended as a modern reinterpretation of swm, with the big virtual desktop taken to the extreme. Exposing controls on a pipe/socket interface and outsourcing controls to sxhkd are ideas from bspwm.
