udn-songbook 1.4.4

songbook and songsheet management for songsheets in ukedown format

udn-songbook

What'cha talkin' about, Willis?

udn-songbook is a class-based abstraction of a songbook, using the ukedown rendering engine. Long-term it is intended to replace most of the code from the ukebook-md tools. In the end, you should be able to take the code from here and create (and render) songbooks with it, producing PDFs and/or HTML (and possibly other formats, if I add them).

Requirements

Python packages

• ukedown (markdown extensions)
• weasyprint (PDF generation)
• pychord (chord management)

development requirements - for future project enhancements

• python-fretboard (chord generation)

The TL;DR

How to use the current functionality

(it only does basic things at the moment)

from udn_songbook import Song
s = song('/path/to/filename')

# list the unique chords in the song
s.chords

# save it to disk
s.save(outputfile)

# transpose by an arbitrary number of semitones
s.transpose(semitones)

# generate a PDF from the current song, using built-in templates
s.pdf()

And to build a songbook, use the SongBook class, with a directory of UDN-format songsheets

from udn_songbook import SongBook
mybook = SongBook(inputs=['directory1', 'directory2', 'someotherfile.udn'])

Songbooks have an index auto-generated, and do not support mutiple songs with the same ID (which is essentially "Title - Artist").

If your inputs include multiple songs in this way, the last one imported will be used. So name them carefully.

A Songbook in this context is a collection of song objects with additional metadata, such as an index.

Tools

The pip package also installs 2 commandline tools, aimed at managing individual songsheets:

udn_transpose, which allows in-place (or optionally to a new file) transposing of an existing songsheet by an arbitrary number of semitones. The transposition is added to metadata

udn_songsheet, which renders a UDN songsheet to a file in either PDF (default) or HTML format. it also supports in-place transposition, without affecting the original input file.

what you need to use this:

• a directory full of UDN-format files.
• templates:
  • index.html.j2
  • song.html.j2
• stylesheets (up to you, you can pass their names and location to the methods)
  • pdf.css
  • ukedown.css
