UI hints
========
* Enqueue tracks in the playlist with Ctrl+RightButtonClick, like in
Amarok.
* Mark a track as "stop after this track" with Ctrl+MiddleButtonClick.
* Press return in the tree view search line to append all the search
results to the playlist, starting playback if the playlist was empty
and the player stopped. Press return as well in the playlist search
line to start playing the first track in the search result.
DBus interface
==============
Minirok exports a DBus interface; the object path is /Player, and the
service org.kde.minirok. There are functions to perform playlist actions
(Play, Pause, PlayPause, Stop, Next, Previous, StopAfterCurrent), and a
function to retrieve the currently playing track, "NowPlaying".
This last functions comes in two flavours: without an argument, it will
return a string like "Artist - Title", or just "Title" if there's no
known artist. However, you can pass a string argument that will be
formatted against a dict of the tags with the Python % operator. For
example:
% qdbus org.kde.minirok \
/Player NowPlaying "%(Artist)s - %(Title)s [%(Album)s]"
Do not forget the "s" after the brackets, it's needed by Python.
There is also an AppendToPlaylist function, which does the same as
`minirok --append`. The function takes a list of paths as argument, so
to invoke it you must place the arguments between brackets, like this:
% qdbus org.kde.minirok \
/Player AppendToPlaylist '(' /path/to/file.mp3 ... ')'
Note that you have to specify the full paths of files, or it won't work.
Regular expressions
===================
Instead of reading tags from audio files, a Python regular expression
can be used to guess them from the filename. The full patch will be
searched, but the regular expression does not need to match the full
path (for pythonistas, it'll be a re.search, not a re.match). The tags
will be extracted from the named groups of the match, namely: "title",
"artist", "album", and "track".
Even if a regular expression is configured, tags will still be read from
the files in the background. This can be configured in the Preferences
dialog so that they are never read, or only if the regular expression
did not match. A regular expression match with an empty "title" group is
considered as failure to match.
An example of a simple regular expression that matches "Artist - Title.mp3"
would be:
'/((?P<artist>.+?) - )?(?P<title>.+)\.[^.]+$'
A more elaborated one, the one I use:
'(?i).*?/(\(\d+\) )?(?P<album>[^/]+(/(CD|vol|disco) *\d+)?)/((?P<track>\d+)_)?((?P<artist>[^/]+?) - )?(?P<title>[^/]+)\.[^.]+$'
This matches, case insensitively:
.../Album/Artist - Title.mp3
.../Album/07_Artist - Title.mp3
.../(year) Album/07_Artist - Title.mp3
.../(year) Album/cd 1/07_Artist - Title.mp3
