Using a playlist is a good idea.
Here's a python script which reads all tracks from a LMS playlist, runs
a replace on the path name, and executes a local command with the paths
as an argument:
Code:
--------------------
#!/usr/bin/env python3
import urllib.request
from urllib.parse import urlparse
from urllib.parse import unquote
import json, subprocess
pls_name = "bad tags"
url = "http://lms:9000/jsonrpc.js";
path_server = "/data/music"
path_client = "/data/client"
exec_cmd = ["tageditor"]
headers = { 'Content-Type': 'application/json'}
req = urllib.request.Request(url, json.dumps( {"id":1,
"method":"slim.request", "params": ["-", ["playlists", 0, 1,
"search:"+pls_name]]}).encode('utf-8'), headers)
with urllib.request.urlopen(req) as response:
result = response.read()
res = json.loads(result.decode("utf-8"))
if res and 'result' in res and res['result'] and 'playlists_loop' in
res['result'] and res['result']['count'] == 1:
req = urllib.request.Request(url, json.dumps( {"id":1,
"method":"slim.request", "params": ["-", ["playlists", "tracks", 0, 999,
"playlist_id:"+str(res['result']['playlists_loop'][0]['id']),
"tags:u"]]}).encode('utf-8'), headers)
with urllib.request.urlopen(req) as response:
result = response.read()
res = json.loads(result.decode("utf-8"))
if res and 'result' in res and res['result'] and
'playlisttracks_loop' in res['result']:
alltracks = exec_cmd
for track in
res['result']['playlisttracks_loop']:
alltracks.append( unquote( urlparse(
track['url']).path).replace( path_server, path_client))
cp = subprocess.run( alltracks,
stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
if cp.returncode != 0:
print("Error: exec failed
rc:{}\noutput:\n{}".format( cp.returncode, repr( cp)))
else:
print("Error: failed to get tracks for playlist
{})".format( res['result']['playlists_loop'][0]['id']))
else:
print("Error: playlist {} not found (result: {})".format(
pls_name, repr( res)))
--------------------
