NAME

ly-fu - play or display lilypond snippets

SYNOPSIS

  $ export MIDI_EDITOR=timidity
  $ export SCORE_VIEWER=xpdf
  $ ly-fu --instrument=banjo c des ees c des bes c aes
  $ ly-fu  -i=trumpet --open "c8 g'4 c,8 g'4 c,8 g'2"
  $ echo c e g | ly-fu -

This utility assumes Mac OS X and timidity by default; set the MIDI_EDITOR and SCORE_VIEWER environment variables, or adjust this code as necessary. zathura is a handy PDF viewer, if available:

  function open {
    zathura "$@" 2>/dev/null &|
  }

DESCRIPTION

Plays and possibly displays lilypond snippets entered at the command line. The MIDI_EDITOR environment variable should be set to a program that can play MIDI files, and the SCORE_VIEWER optionally set to a PDF viewer. (Or edit the source code as necessary.)

http://www.lilypond.org/ and in particular the Learning and Notation manuals should be consulted to understand the lilypond syntax.

OPTIONS

This program currently supports the following command line switches:

--absolute

Assume lilypond absolute notation.

--instrument=instrument

Set MIDI instrument (see lilypond docs and ZSH compdef script).

--layout

Save the MIDI and other various files (they are unlinked by default).

--open

Show the score via the SCORE_VIEWER program.

--partial=lilypond fragment

A lilypond fragment played once at the beginning.

--relative=note

Specify what note the input is relative to.

--repeats=count

How many times to repeat the (non-partial) input.

--silent

Do not play the MIDI.

--sleep=seconds

Kluge sleep before unlinking temporary files (if SCORE_VIEWER is slow, or so forth).

--tempo=tempo

What the tempo is (in quarter notes, e.g. 120 or the like).

--verbose

Show output from lilypond and the MIDI player.

FILES

A ZSH completion script is available in the zsh-compdef/ directory of the App::MusicTools distribution. Install this to a $fpath directory.

BUGS

Reporting Bugs

If the bug is in the latest version, send a report to the author. Patches that fix problems or add new features are welcome.

Known Issues

STDERR hidden by default, so if you feed lilypond bad input, you will not see or hear anything, besides the PDF failing to open, or the music failing to play. Hence the --verbose flag.
