  15. #A script that downloads and register lyrics in the appropriate folder
  16. #And displays them in the terminal
  17. #
  18. #This program requires wget, pcregrep and the html-xml-utils debian package (also available on Archlinux's AUR)
  19. #This program also requires a web browser and a text editor (Defaults to firefox and pluma)
  20.  
  21. #Use :
  22. # $lyrics.bash artistname songname
  23. #This prints the lyrics to the song in the terminal ;
  24. #if they have to be fetched from a distant website, the program will ask for confirmation, then register them for future consultation
  25. #WARNING : NOTE THAT BOTH THE ARTIST NAME AND THE SONG NAME SHOULD BE WRITTEN IN CAMEL CASE.
  26. #This script assumes that they are in camel case at various points.
  27.  
  28. # $lyrics.bash artistname
  29. #This prints out the content of the folder with the name artistname, in the lyrics folder.
  30.  
  31. # $lyrics
  32. #This prints out the content of the lyrics folder itself
  33.  
  34. #The convention followed by this script is that the folder in the variable $lyricsfolder contains folders named after artists
  35. #These folders in turn contain files named after the artist and the song which contain the lyrics
  36. #This program uses the following convention : lyrics to a specific song by a specific artist have the following path :
  37. # $lyricsfolder/$artistname/$artistname_---_$songname
  38. #
  39. #If no such file exists with this specific path, this program will then attempt to download them
  40. #and write them to a new file with this path, after asking for confirmation
  41.  
  42. #If no folder called $artistname exists, the program will ask for confirmation in creating it and exit immediately if this is denied
  43.  
  44. #Configuration variables
  45. #This variable is the path to the lyrics folder where every lyrics file will be, in the appropriate subfolder
  46. lyricsfolder="$HOME/textes/Paroles_de_chansons"
  47. #lyricsfolder="$HOME/lyrics"
  48.  
  49. #This can either be a new folder or an existing one.
  50. #Any pre-existing subfolders and files not conforming to the naming convention will be ignored by the script
  51.  
  52. #If all else fails, the script will ask you for confirmation to send you on a google search and then google the lyrics
  53. #and open a text editor so that you can copy them yourself.
