RLP is a lyric fetching script for Amarok written in Ruby.
The RLP philosophy:
1) Keep the number of search engines to a minimum.
2) Use the best search engines.
3) Search effectively and efficiently.
Search Engines (in order of search priority):
1) LyricWiki - a reliable, well-maintained, and constantly updated lyric site
2) JustSomeLyrics - good for less popular music (not found on LyricWiki)
__Basic Search Algorithm Description__
Processing Artist/Song Data:
1) Artist and song data are first "processed"; this involves stripping any useless/junk characters that would otherwise prevent useful search results.
2) Original artist and song data are still preserved. In the event that a search with the processed info fails, we'll try it again but with the unprocessed data.
3) Adding to 2... RLP will retry only if all the following conditions hold true:
- The processed and unprocessed song information differs
- retry is set to true in configuration options
- The search method itself is set to retry (as defined by me)
LyricWiki Search Methods:
1) Guess the song url: This method "guesses" the song url from the song/artist data. So, if the meta tags on your music are accurate, then you'll have no problems getting lyrics.
2) Google search: This method searches google using the song/artist data and grabs the first search result. It then checks the "type of page it retrievied:
- If it's a song page, return the lyrics
- If it's the artist's main page or an album page, find the song link from the page
JustSomeLyrics Search Methods:
1) Google search: This method searches google using the song/artist data and grabs the first search result.
-- Benefits of RLP --
1) I actively develop and constantly test my code (see the Test Cases suite I've included in debug.rb).
2) The general trend with lyrics scripts seems to be: "more search engines = better results"
I disagree, and instead believe: "more search engines = bloated and slow script that searches ineffectively"
3) I'm open to suggestions (see Contact information below).
-- Configuration --
The configuration is located at the top of lyric_parser.rb, and is quite minimal (and in my opinion, not needed).
-- Dependencies --
Ruby 1.8 (ruby1.
Standard Ruby Libraries (libruby1.
kdebase-bin (for error notifications)
-- Contact --
Having trouble getting lyrics for a song even though it's on one of the above search engines?
Know a better lyric search engine that I should include in future releases?
By all means, email me about it, and I'll consider implementing it.

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- Korundum (LoadError) from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require' from /home/pablo/.kde3.5/share/apps/amarok/scripts/lyric_parser/amarok.rb:8 That's the error I get. I'm running Gentoo, with ruby-1.8 installed.
I'm on Debian and I had to install libkorundum0-ruby1.8.
Ah, that did it. Thank you.
I'm currently working on extending my html parsing library. What this means for you guys is that I'll be able to add more search engines, and I should be able to implement them quite fast. In terms of search engines to add, I'm considering sing365.com, but am not entirely decided. Do you guys have any favourite lyric databases that you think I should add in the next release?
Other than the stock lyric tools, none have worked well for me. This does a great job. I have to clean up the lyrics in the edit information but at least I actually have them. Even for the hard to find stuff. Thanks!
it no work. get two items, on a page.rb......thing. and it repeatedly crashes.
Please post amarok's error message and tell me the track/artist that you experience a crash from, and I will look into it right away.
I believe your problem may be that you don't have some standard Ruby libraries installed (libruby1.8). I've now added error notifications for this, so if you try installing the newest version and running it, you should get an error dialog to confirm this.
i eventually figured out what was wrong, i was trying to run the wrong thing, there's extraneous entries, i was trying to run them. http://img.photobucket.com/albums/v413/sKaar/oddstuff/ruby-buggery.png and it appears to work, well enough, except that it didn't pick up my ray stevens stuff.
didn't work for mel torme either, but it dug up orgy and green jelly just fine.
I'll do my best to make sure the next release can find these artists for you.
Works GREAT! Gets lyrics i haven't found with other scripts! Cool, Thanks!
Thanks for the feedback, and enjoy!
