App::Music::ChordPro::A2Crd - convert lyrics and chords to ChordPro


  perl -MApp::Music::Chordpro::A2Crd -e run -- [ options ] [ file ... ]

(But noone does that.)

When the associated chordpro program has been installed correctly:

  chordpro --a2crd [ options ] [ file ... ]


This program, referred to as a2crd, will read a text file containing the lyrics of one or many songs with chord information written visually above the lyrics. This is often referred to as crd data. a2crd will then generate equivalent ChordPro output.

Typical a2crd input:

    Title: Swing Low Sweet Chariot

          D          G    D
    Swing low, sweet chariot,
    Comin’ for to carry me home.
          D7         G    D
    Swing low, sweet chariot,
                  A7       D
    Comin’ for to carry me home.

      D                       G          D
    I looked over Jordan, and what did I see,
    Comin’ for to carry me home.
      D              G            D
    A band of angels comin’ after me,
                  A7       D
    Comin’ for to carry me home.

Note that the output from the conversion will generally need some additional editing to be useful as input to ChordPro.

a2crd is a wrapper around App::Music::ChordPro::A2Crd, which does all of the work.

chordpro will read one or more text files containing the lyrics of one or many songs plus chord information. chordpro will then generate a photo-ready, professional looking, impress-your-friends sheet-music suitable for printing on your nearest printer.

chordpro is a rewrite of the Chordii program.
