Start typing in keywords to list out entries. Press Enter to select an entry. The selected entry will be run through a shell.
|
|
To set spmenu options, you modify \$RUNLAUNCHER_ARGS in $config. See 'spmenu --help' for a list of valid arguments to add to the variable.
|
|
To configure spmenu itself, you may copy ${DESTDIR}${PREFIX}/share/spmenu.conf to ~/.config/spmenu/spmenu.conf.
|
|
|
|
By default, spmenu_desktop will cache entries for speed reasons. You can find these entries in ~/.config/spmenu/desktop/cache.
|
|
If you make changes to .desktop files (not new entries, modified old entries), you need to clear the cache for the changes to appear. Simply delete the directory to do this.

# You may create those functions below. For 'post_func', the selected item is passed as an argument (\$1).
|
|

|
|
# For example, to implement a basic history file:
