groff_lilypond +transforms sheet music in the +.FONT CI lilypond +language in a +.FONT CI groff +file such that +.FONT CB groff +can display them. +. +. +.P +Without arguments, +.FONT CB groff_lilypond +reads from standard input. +. +A single file can be given as an argument. +. +. +.\" -------------------------------------------------------------------- +.SH "HOW THE TRANSFORMATION WORKS" +.\" -------------------------------------------------------------------- +. +A +.FONT CI lilypond +part within a structure written in the +.FONT CI groff +language is the whole part between the marks +.FONT CB ".lilypond start" +and +.FONT CB ".lilypond end" R . +. +A +.FONT CI groff +file can have several of these +.FONT CI lilypond +parts. +. +. +.P +These +.FONT CI lilypond +parts are sent into temporary files with the file name extension +.FONT CB .ly R . +. +. +.P +These files are transformed by the +.FONT CB lilypond +program into +.FONT CI pdf +files, using +.EX +.FONT CB "lilypond \-\-pdf \-\-output=" I file-name +.EE +for each +.FONT .ly +file. +. +The +.I file-name +must be provided without the extension +.FONT CB .pdf R . +. +By this process, a file +.FONT CI file-name CB .pdf +is generated. +. +. +.P +The next step is to transform these +.FONT CI pdf +files into a +.FONT CI ps +file. +. +This is done by the +.FONT CB pdf2ps +program using +.EX +.FONT CB "pdf2ps " CI file-name CB ".pdf " CI file-name CB ".ps" +.EE +. +. +The next step creates an +.FONT CI EPS +file from the +.FONT CI ps +file. +. +This is done by the +.FONT CB ps2eps +program using +.EX +.FONT CB "ps2eps " CI file-name CB ".ps" +.EE +. +. +.P +By that, a file +.FONT CI file-name CB .eps +is created for each +.FONT CI lilypond +part in the +.FONT CI groff +file or standard input. +. +. +.P +The last step to be done is replacing all +.FONT CI lilypond +parts by the +.FONT CI groff +command +.EX +.FONT CB ".PSPIC " CI file-name CB .eps +.EE +. +. +.P +That new +.FONT CI groff +structure is sent to standard output. +. +It can either be saved in a file or piped to groff for a display. +. +. +.\" -------------------------------------------------------------------- +.SH "TEMPORARY FILES" +.\" -------------------------------------------------------------------- +. +By the transformation process, there are many temporary files +generated. +. +All of them except the +.FONT CI EPS +files are deleted when the +.FONT CB groff_lilypond +process is finished. +. +. +.P +These +.FONT CI EPS +files are stored in a temporary directory. +. +But they cannot be deleted by the transformation process because they +are needed for the display which can take a long time. +. +. +.\" -------------------------------------------------------------------- +.SH "DISPLAY" +.\"
