Glyr is a music related metadata searchengine, both with commandline interface and C API
h1. Glyr is a search engine for music related metadata
The finest search you can buy for no money ^TM^
It comes both in a command-line interface tool and as a C library, both with an easy to use interface. The sort of metadata glyr is searching (and downloading) is usually the data you see in your musicplayer. And indeed, originally it was written to serve as internally library for a musicplayer, but has been extended to work as a standalone program which is able to download:
|cover||Coverart (front images supported only)|
|artistphotos||Photos of a certain band (press or live)|
|artistbio||Artist biography from various sites|
|review||album reviews from various sites|
|albumlist||A list of albums from a specific artist.|
|tags||Tags, either related to artist, album or title|
|relations||links to wikipedia, myspace, musicbrainz ...|
|tracklist||tracklists of an album|
|guitartabs||guitartabs in textual form|
|backdrops||Large artist photos, suitable for backgrounds|
To prevent disambiguation the following terms are used below:
* glyrc is the command-line interface to libglyr. * libglyr is the library behind, which may be used by your program. * a getter is a type of metadata to download, e.g. @[email protected], sometimes also called fetcher * a provider is a source libglyr queries in order to find the data. * glyros is the ruby wrapper for this lib. Currently it is not maintained.
h2. GETTING STARTED
See the "compile page":https://github.com/sahib/glyr/wiki/Compiling.
See the "examples in src/examples":https://github.com/sahib/glyr/wiki for a quickstart. There's also a more "gentle (and brief) introduction.":https://github.com/sahib/glyr/wiki/Introduction-to-libglyr Also see the "API Reference":http://sahib.github.com/glyr/doc/html/index.html Please note: Since version 1.0.0 the API will be stable, and will only be open for extensions.
Please refer to @glyrc [email protected] which gives you a brief introduction to the arguments you can pass, See the "wiki":https://github.com/sahib/glyr/wiki/Commandline-arguments for more detailed information about the options.
h3. Anyone using it already?
h3. Glyr.. such a silly name! Why?
Indeed. Should have named it 'Glyros' (too late, damnit).
h3. Is it hard to write something with it?
Some knowledge of C might be required, but the code is straight forward most of the time.
Bash scripts are pretty straight-forward: @glyrc cover --artist Equilibrium --album Sagas --write '/tmp/:artist:_:album:.:format:' --callback 'sxiv ":path:"'@
Additionally there are bindings to Python and Ruby:
h3. How..how am I supposed to use it?
Well, as normal user you could use @[email protected] to retrieve some metadata in a batchlike fashion. As developers you have lots of option, you could write glyr-plugins for musicplayers (gmpc!), set up a webserver with this, hack up little scripts showing covers on the desktop.. everything related to musicmetadat is possible here. You could also extend libglyr itself but that's a little harder.
h3. Isn't there musicbrainz already?
i.e. glyr finds metadata for musicplayers while musicbrainz finds data for CD Rippers and taggers.
Glyr is a client program which hops over several sites and does not cache anything, unless you do it yourself. You could of course let glyr run on a (remote) server, and cache all results to do something similiar.
See the AUTHORS file that comes in glyr's distribution. See also COPYING to know about your rights.
h2. I CAN HAZ HELP?
If you found one: Meh. Sorry for that. If you file a bugreport: Hey, thank you!
Use the "Issue Tracker":https://github.com/sahib/glyr/issues to share your find. Alternatively you may drop me a mail at [email protected]
If you hacked one: Excellent! Send it to me via mail or see below. If you want to add new providers you should look at the existing provider plugins to get an idea how to write one. Starting with lib/cover/lastfm.c isn't a bad idea either, because it is one of the very simple ones.
Take the usual Git(Hub) approach:
If you're not familiar with git, or just don't like it, you can also send me the patch via mail: [email protected]
Thanks for any help in advance!
h3. WRITE SOFTWARE THAT USES GLYR
May sound strange, but you're giving me a reason to maintain it, write new providers etc. Also bugreports (well, there are no bugs, just in case) are appreciated, or just questions. Those help to make the documentation more clear.
You also might consider a small (CS-Students are already motivated by 1 Cent ) donation if you use feel like it: (For now only possible via Flattr or "Paypal":http://sahib.github.com/donate.html , you gonna need an account there - Sorry)
As usual, no warranty is granted that this software works like expected. Refer to the LGPLv3 copy you got with libglyr. It is "here.":https://github.com/sahib/glyr/blob/master/COPYING Glyr is just a way to find the data, it does not own any rights on the data it found.
All retrieved items are copyrighted by their respective copyright owners.
 Glyr has not been tested on Mac OSX yet. If you own a Mac, any help with 'porting' glyr is highly appreciated. My guess would be that no to almost no changes need to be done though.
