From Erlang Community
Here I will gather some thoughts about metaprogramming in Erlang. Hopefully this will result in an implementation too (some parts have already been implemented). I put this here so that I can get input and the result will become a HowTo.
This is very much a work in progress. Please don't delete anything, just add your comments.
What is metaprogramming?
I won't go into the gory details here, there are plenty of papers on the matter. What I do mean by MP here is the capability of writing programs that handle programs.
Erlang has already support for MP. It is composed from two parts:
- the parse trees for Erlang code are regular Erlang terms
- through the parse_transform concept, one can manipulate a module's parse tree before it is compiled

Don't blame me if this stuff blows in your face or if your cat starts barking like a dog! :-)
