-# terminals swallow windows
+swallow
+=======
-## Description
+Description
+-----------
This patch adds "window swallowing" to dwm, a la `rio` from Plan 9.
-Windows that are marked with the `isterminal` flag (settable using rules in `config.h`) will swallow a window opened by any descendant processes.
-For example, if you open a terminal and then in that terminal type `xclock`, the `xclock` window takes the place of that terminal window.
-Closing the `xclock` window restores the terminal window in the current position.

-This patch is useful for users who tend to do most or all of their work from the command line, but sometimes need to use a graphical program.

+from the command line, but sometimes need to use a graphical program.
This patch avoids cluttering the desktop with unused terminals.
-(`dmenu` could be used, but if you are deep in a directory hierarchy and want to, say, view a PDF, cutting and pasting the path to `dmenu` takes longer than just running `mupdf`.)

+Notes
+-----
-## Note
-The window swallowing functionality requires `dwm` to walk the process tree, which is an inherently OS-specific task.
-Only Linux is supported at this time.
-Please contact the author (jking_AT_deadpixi.com) if you would like to help expand the list of supported operating systems.
