Make it possible to maintain upmpdcli-radio.conf via Moode’s interface

Code:
#!/usr/bin/python3

# utility script to read the .pls files in the moOde r4.4 RADIO directory

# and create counterpart upmpdcli-radio.conf entries, complete with

# artUrl links to the station-logo thumbnails



# prints output to command line; output can be redirected to a file 

#    which can replace or be concatenated with /etc/upmpdcli-radio.conf



# Limitations: 

#   - the artUrl references a specific moOde player by hostname. 

#       - UPnP apps accessing this player must be able to resolve this hostname

#       - If the hostname changes, all artUrl entries must be changed

#   - ignores multiple entries in a .pls file

#   - takes station name from the .pls file name and ignores Title lines in

#     the .pls file, many are too long to be of use; some differ in subtle ways

#   - assumes station logos are in .jpg format which is currently true; could be 

#     modified to test for the actual logo file format, e.g., jpg, png, etc.

#   - uses thumbnails rather than full logo art. This may be a limitation

#     to some, a feature to others --- thumbnails look good in a directory listing,

#     not so good in full screen. LOGO_DIR_rel could always be changed.

#



import os, urllib.parse



# maybe overly cautious, but don't assume there 

# is no whitespace in .pls entries 

def getURLfromPLS(dir, basename):

  with open(dir + basename, "r") as file:

        break

    close(file)

 

# some useful strings based on moOde r4.x directory structure

# later code assumes there are no unsafe characters in these strings
