• File channels/exportcat.py — part of check-in [b784d408c1] at 2015-04-09 14:50:54 on branch action-mapfmts — Still some parameter renaming in action module to do. Optional support for row={} parameter in play/record calls, in case .pls/.m3u needs to be constructed (to retain title=). Adapt action playlist exporting to wrapper object, which preconverts plain URL lists or [rows] list, can itself call convert_playlist(), and optionalized file writing. Rewrite main save() and exportcat.save() to utilize new save_playlist(). Implement overwrite confirmation for Save-as dialog. (user: mario, size: 1923) [annotate] [blame] [check-ins using]

# Use "Extensions > Export all" in the desired channel and category,
# to export all station entries at once. Currently just export PLS,
# which in turn references other .pls file).  Luckily most players
# can cover up for this horrid misdesign.
#
# This is a workaround until the main GUI supports selecting multiple
# rows at once, and the action.* module has been overhauled to export
# a bit more deterministically.
