Rebus template language compiler based on Ruby dynamic evaluation. Minimalistic and customizable.
For example this document was rendered from readme.md.rbs template.
gem install rebus
Rules are:
- input is interpreted line by line
- there are 3 different line types recognized by the following prefixes:
#- a comment line skipped during compilation$- a code line evaluated during compilation- any other - a string line with possible interpolated code (see Ruby string interpolation rules)
Sample (stealed and translated from ERB documentation):
