Interacting With Unix (StumpWM Manual)

## 12 Interacting With Unix ¶

Command: run-shell-command cmd &optional collect-output-p ¶

  Default Values:

        collect-output-p  nil

  Run the specified shell command. If collect-output-p is `T` then run the command synchonously and collect the output. Be careful. If the shell command doesn’t return, it will hang StumpWM. In such a case, kill the shell command to resume StumpWM.

Function: programs-in-path &optional full-path path ¶

  Default Values:

        full-path  nil
        path       (stumpwm:split-string (stumpwm:getenv "PATH") ":")

  Return a list of programs in the path. If full-path is t then return the full path, otherwise just return the filename. path is by default the `PATH` evironment variable but can be specified. It should be a string containing each directory seperated by a colon.

Function: pathname-is-executable-p pathname ¶

  Return T if the pathname describes an executable file.

Function: pathname-as-directory pathspec ¶

  Converts the non-wild pathname designator PATHSPEC to directory form.

Function: run-or-raise cmd props &optional all-groups all-screens ¶

  Default Values:

        all-groups   stumpwm:*run-or-raise-all-groups*
        all-screens  stumpwm:*run-or-raise-all-screens*

  Run the shell command, cmd, unless an existing window matches props. props is a property list with the following keys:

  `:class`

    Match the window’s class.

  `:instance`

    Match the window’s instance or resource-name.

  `:role`

    Match the window’s `WM_WINDOW_ROLE`.

  `:title`

    Match the window’s title.

  By default, the global *run-or-raise-all-groups* decides whether to search all groups or the current one for a running instance. all-groups overrides this default. Similarily for *run-or-raise-all-screens* and all-screens.

Variable: *shell-program* ¶

  The shell program used by `run-shell-command`.

Function: getenv var ¶

  Return the value of the environment variable.

Function: (setf getenv) val var ¶

  Set the value of the environment variable, var to val.
