A while back, I wrote a post about macros in Scheme. Today I want to take a look at how one might begin to implement a macro system. In Scheme, whether you use syntax-rules or syntax-case do write your macros, at some point you’ll write patterns and templates. Macros match their input against a pattern and then use this to instantiate a template.
