srcgen: The semantic source code generation framework

Project description


Srcgen is a semantic code generation framework. Being semantic means that the code generator and the generated code bear similar structure, as well ; for instance, the body of an if statement is indented both in the generating and generated code. Here’s a short example:

>>> from srcgen.python import PythonModule
>>> m = PythonModule("foo")
>>> m.import_("sys")
>>> m.import_("os")
>>> m.sep()
>>> m.stmt("x = 5")
>>> with m.if_("x > 8"):
...     m.stmt("print 'oh no'")
>>> with m.else_():
...     m.stmt("print 'oh yes'")
>>> print m
import sys
import os

x = 5
if x > 8:
    print 'oh no'
    print 'oh yes'

You can nest deeper, of course, as well as extract common pieces of code into functions:

m = PythonModule("foo")
with m.class_("MyClass"):
    with m.method("__init__", "


At the moment Srcgen supports:

  • C
  • Python
  • Cython

More languages will be added per public demand (you’re welcome to join the effort!)
