Writing a domain specific macro processor in ruby

[Handy Gandy]

I'm thinking of something like the m4 processor ( of autotools fame or
infamy ), but with only a few domain specific built-in macros.

Can anyone offer some helpful hints?

Look at existing text/template expansion projects first, e.g.
* erb / erubis
* liquid
* moustache

Google "ruby templating" for more. Some are geared towards generating
HTML, but others are more general-purpose.

What is the application? What is the target language?
