Campfire - chordpro python

Simple songbook ,,typesetting'' ,,system'' rendering chodpro files

python campfire.py ~/MySong.cho

Recommended ussage:

1. Run python main.py mysong.cho transforms to mysong.pdf
2. OPTIONAL - Grab Visual Studio code and install ChordPro extension to colorize .cho files

usage: campfire.py [-h] [--format FORMAT] [infile]

Process songbook.

positional arguments:
  infile

optional arguments:
  -h, --help       show this help message and exit
  --format FORMAT  [pdf] html

Features:

• Real UTF8 support without any woodo-magic
• Produces nicely large printable pdfs which you can take to pub
• Keeping great support for KISS principe - just look for example cho file
• Multiplatform - using only python libraries without any native dependencies
• Great extensibility and modularity - write your own renderer
• PDF and HTML formats are supported
• Ligatures ;)

Supported renderers

• PDF - Primary renderer
• HTML - Aspiring to be primary renderer, but there is long way to go(page wrapping) maybe for multiple songs

Why another system?

• lilypond - perfect typesetting but doesn't work well simple songs
• chordpro is old and ... perl. Update: I'm not able to run version 6 on manjaro.
• musescore - typesetting is perfect, MIDI support is perfect, ... use this if you want more features
• tex - packages - overhelming complexity for single sheet with poor lack of UTF8 support

Developing & hacking

Requirements - libs
