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.
Unlike dwm, echinus does not need to be re-compiled after changes have been made to the config. It supports Xft (freetype) out of the box and has the option of configurable titlebars.
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"
After making changes to Template:Filename, you can reload the config without recompiling by restarting echinus, with Template:Keypress + Template:Keypress + Template:Keypress. This keybinding, and any other, can be customized to suit your preference or muscle-memory.
Further details for manipulating windows are in the manpage and the Template:Filename.
