msdparser
A robust & lightning fast MSD parser for Python. MSD is the underlying file format for the SM and SSC simfile formats used by StepMania, as well as a few older formats like DWI.
Quickstart
parse_msd() takes a named file or string argument
and yields MSDParameter instances:
>>> msd_data = """
... #VERSION:0.83;
... #TITLE:Springtime;
... #SUBTITLE:;
... #ARTIST:Kommisar;
... """
>>> from msdparser import parse_msd
>>> for param in parse_msd(string=msd_data):
... print(
... "key=" + repr(param.key),
... "value=" + repr(param.value),
... )
...
key='VERSION' value='0.83'
key='TITLE' value='Springtime'
key='SUBTITLE' value=''
key='ARTIST' value='Kommisar'
MSDParameter instances stringify back to MSD.
They can be created from a sequence of strings,
typically the key and value:
>>> from msdparser import MSDParameter
>>> pairs = [('TITLE', 'Springtime'), ('ARTIST', 'Kommisar')]
>>> for key, value in pairs:
... print(str(MSDParameter([key, value])))
...
#TITLE:Springtime;
#ARTIST:Kommisar;
Prefer to use MSDParameter
over interpolating the key/value pairs between #:; characters yourself.
The str() implementation inserts escape sequences where required,
preventing generation of invalid MSD.
