Topic: Just finished up a 0.1 version of a LIRC (Linux Infrared Control) plugin for the Exaile media player. Now you can use your remote with Exaile efficiently. The plugin is in the public repository and is called Lircaile.
I haven’t touched Python much as of yet, but I’m pleased with it: it appears to be a consistent language. Well, here’s my 0.1 effort. I desperately wanted to have some fun with introspection, but I have the feeling the nested exception logic is a bit… unusual.
Update #20110222: Updated the inline code preview below to 0.3.0.

Hi, and thanks for this plugin !
I’ve just tested it today, and it works great.
However, I can’t figure out how to get the exaile function list I could put in “config =” in an .lircrc file.
The basic sample help, and I can find some obvious function like “stop”, but an exaustive list would be great…
Can you help me with that, or indicate how to obtain it ?
Thanks a lot,
yagraph

The details are in handleCode(). If you define ‘config=yadda’ in your ~/.lircrc, then lircaile will look for a function ‘yadda()’ in the exaile.queue object, and subsequently in the exaile.player object.
The exaile.queue object is, on my machine, an instance of PlayQueue as found in
/usr/lib64/exaile/xl/player/queue.py. The exaile.player object maps to NormalPlayer in/usr/lib64/exaile/xl/player/engine_normal.py.An exhaustive list would therefore contain all functions in these classes, of which few make sense to map a remote button to ;-)

Thanks Wicher,
you’re right, there’s a lot of functions, and really few make sense to use with a remote button ;)
I searched around files you mention, and others, but couldn’t find anything more relevent than what your sample provided (except “stop”).
To say it short : I look for a way to
= seek forward and rewind (I tried with “seek +10″, “position +10″, “scroll +10″, with no success).
= toogle the three button above play and stop : track randomness, toogle repeat playback, and dynamic tracks adding…
but I do not feel it’s possible actually, and I can’t find than in python files.
If you have any idea, I would be pleased to hear it, that’s my last request, I promise !

There actually is a seek() in engine_normal.py, but it takes an absolute position. I added seeking support in lircaile 0.3.0, check my repo.
I absolutely don’t mind hearing from you, that’s what the comment form is for ;-)
Please test 0.3.0.
Thanks a lot Wicher, I didn’t expect you to do custom dev for me ;)
Sadly, I can’t install your latest version, for some reason…
Adding the plugin with Exaile Preference menu, I obtain :
“Plugin file installation failed !” “PLugin archive is not in the correct format”
I updated Exaile to 0.3.2.1 to be sure, but no more result (Xubuntu 10.10 64 bits install).
Do I miss something, or there is some bug in your package ?
Cheers

I seem to have zipped where I should’ve targz’ed.

Ok, its works, and it rocks, thanks again !
just a detail : maybe you should use a config of seek “+5″ instead of “+10″ : a value of 5 give a 10 seconds jump, which is fine for my tests.
That’s a quirk in your lirc setup. You might solve it by twiddling the
repeatanddelayparameters in your ~/.lircrc, check the docs.
