Writing a compiler for a DSL in python

Question

I am writing a game in python and have decided to create a DSL for the map data files. I know I could write my own parser with regex, but I am wondering if there are existing py

Answer 1

I have written something like this in work to read in SNMP notification definitions and automatically generate Java classes and SNMP MIB files from this. Using this little DSL, I could write 20 lines of my specification and it would generate roughly 80 lines of Java code and a 100 line MIB file.

To implement this, I actually just used straight Python string handling (split(), slicing etc) to parse the file. I find Pythons string capabilities to be adequate for most of my (simple) parsing needs.

Besides the libraries mentioned by others, if I were writing something more complex and needed proper parsing capabilities, I would probably use ANTLR, which supports Python (and other languages).
