#    version 2012/09/27

#    NB The shell, not bash, is invoked in the hope that
#    dash will be used, as it is much faster.

# Usage: add
# <menu id="places" label="Places" execute="/path/to/dash_places_menu.sh ~/" />
# to your .config/openbox/menu.xml

# or, if you want the "recent files" menu incorporated at the top, use:
# <menu id="places" label="Places" execute="/path/to/dash_places_menu.sh --recent ~/" />
# make sure you have recently_opened_menu.sh somewhere, and enter its path below.

# path to your "recent files" script, if you want to incorporate it:
recent_script="$HOME"/scripts/recently_opened_menu.sh

# Command to open folders at "Browse here..." - any file manager
open_folder_cmd=thunar
# Default command to open files with - others might be xdg-open, gnome-open, pcmanfm...
default_open_cmd=exo-open  # exo-open comes with thunar
# Text editor of choice
text_editor=geany

# function to open files with default open command, or alternative command for certain files
# - add other conditions to choice
open_file() {
	[ -x "$1" ] && exec "$text_editor" "$1"     # comment out this line if you don't want to edit executables instead of executing
	#[ -x "$1" ] && exec "terminator -e" "$1"     # uncomment this and comment out previous line to run executables in terminal instead of editing
	[ "${1##*.}" = desktop ] && exec "$text_editor" "$1"     # comment out this line if you don't want to edit .desktop files instead of executing
	exec "$default_open_cmd" "$1"     # use default open command if above conditions not satisfied
}

# extra dotfiles to display in HOME folder (dotfiles are hidden by default)
# edit the list (space separated, surrounded by single quotes) or comment this line out, to taste:
shown_dotfiles='.config .local .Xdefaults .bash_aliases .bashrc .fonts.conf .gtkrc-2.0.mine .profile .xsession-errors'

# By default, this script will display directories separately, before files.
# To change this behaviour, see NOTE1, NOTE2 and NOTE3 below, near end of page.
