Re: musicxml2ly in python

[Jacques Menu]

Hello Sebastian,

This can also be done with a make file, but maybe that is not your use case.

 Doing so offers means to place the generated files in sub-folders and to remove them seamlessly. 

Also, only the .xml files modified or created since the last ‘make’ execution are converted.

Attached is an example Makefile, which I use to convert all the .xml files in a folder with my xml2ly.

It can be used with musicxml2ly too: drop this Makefile in the given folder and use it as shown below. 

‘OPTIONS=...‘ is neccesary in this case because there is otherwise a default ‘-q’ (quiet) to be used by xml2ly. It can be as simple as  ‘OPTIONS=‘.

HTH!

Makefile for converting MusicXML files to LilyPond scores.

Supplied as part of the MusicFormats library, thanks to Dom Fober for providing it.

Output files are written in sub-folders of the current folder.

Available targets are:

  'all' (default) : call the 'lily' target.

  'lily'          : converts the set of MusicXML files to lilypond in folder 

  'pnglily'       : converts the output of 'lily' target to png in folder pnglily

  'pdflily'       : converts the output of 'lily' target to pdf in folder pdflily

  'midilily'      : converts the output of 'lily' target to pdf in folder midilily

  'clean'         : removes the sub-folders containing the results

Options:

  'XML2LY=/path/to/xml2ly

  'OPTIONS=...

  'LILYPOND=/path/to/lilypond

  When those options are not specified, the tools are taken from the current PATH variable,

  and OPTIONS contains '-q' (quiet mode) for xml2ly.
