echinus is a simple and lightweight tiling and floating window manager for X11. Started as a dwm fork with easier configuration, echinus became a full-featured reparenting window manager with EWMH support.
echinus is configured in one simple text file, in Xresources format: Template:Filename. Details for all of the configuration options are in Template:Filename. A section of a sample config file looks like:
Echinus*selected.border: #404040 Echinus*selected.button: #d3d7cf Echinus*selected.bg: #262626 Echinus*selected.fg: #d3d7cf
Rules can be set up to spawn applications in specific tags. The following rule, for example, would open firefox in the "web" tag:
Echinus*rule0: firefox.* web 0 1
Opening applications in a terminal requires that you explicitly set the -title tag when spawning them so that echinus can manage them:
Echinus*spawn0: CA + m = urxvtc -title mutt -e mutt
Similarly, when spawning dmenu, you will need to declare the requisite properties, like so:
Echinus*spawn1: Menu = dmenu_run -fn "-*-dina-medium-r-*-*-*-100-*-*-*-*-*-*" -nb "#1A1A1A" -nf "#696969" -sb "#1A1A1A" -sf "#D3D7Cf"
Further details for manipulating windows are in the manpage and the Template:Filename.
