# Dynamic places menu generator for openbox
# Uses a list of parent directories to provide a menu of subdirectories
# After removing any entries found in an ignore list

#
#
# 1. Save this script to a place you prefer (mine is in ~/.config/openbox/scripts/)
# 2. Make it executable
# 3. Insert a line into your ~/.config/openbox/menu.xml like:
#    <menu execute="perl ~/.config/openbox/scripts/places.py menu" id="pipe-places" label="Places"/>
# 4. Call the pipe-menu in your menu by adding the following line to the same file:
#    <menu id="pipe-places"/>
# 5. Reconfigure OpenBox
# 6. You're done
#
# Important variables if you want to customise the generated menu:
#    manager - File manager which you want to use (nautilus, thunar, pcmanfm, rox-filer, konqueror, dolphin, etc).
#    dirs - The script lists and displays the subdirectories of these directories
#    ignore - Any item exactly matching an entry in this list will not be displayed
#    items - If you want to add a single directory entry to the menu you can do it here
#

import glob
import fnmatch
from os.path import expanduser

# File manager you want to use to open directories
manager = "thunar"

# User home directory. If you hard code this location instead of relying on
# expanduser() then you can remove its import above
home = expanduser('~')

# List of directories whose subdirectories we want to display
dirs = [home, '/mnt/server/']

# List of directories to ignore
# Shell-style wildcards as used by fnmatch are supported
ignore = ['/media/cdrom0']

# Our list of menu items
# If you want to add single directories to the menu without including
# all of their subdirs then put them in here
items = []

# Iterate through dirs
for dir in dirs:
    # Get a list of subdirectories for each dir
    subdirs = glob.glob(dir + '/*/')
    # Alphabetise subdirs. Sorting here is less efficient but preserves
    # directory order specified above. If this doesn't matter to you then
    # remove this line and uncomment "items.sort(key=str.lower)" below
    subdirs.sort(key=str.lower)
    # Append each subdir to the items list
    for sub in subdirs:
        # Replace /home/user with ~ before appending to items (looks better)
        sub = sub.replace(home, '~')
        # Strip trailing / characters
        sub = sub.rstrip('/')
        items.append(sub)

# Iterate through ignore list and remove matches from items
for i in ignore:
    matches = fnmatch.filter(items, i)
    for m in matches:
        try:
            items.remove(m)
        except ValueError:
            pass

# Alphabetise directory list. Read comment for sort() above before uncommenting
#items.sort(key=str.lower)

# Output xml for the openbox menu
print '<openbox_pipe_menu>'
# Each item becomes a menu entry
for i in items:
    print '<item label="' + i + '">'
    print '<action name="Execute">'

    print manager + " " + i
    print '</execute>'
    print '</action>'
    print '</item>'
print '</openbox_pipe_menu>'
