Would it be acceptable to offer a patch that makes this utility more
usable in the context of other Python programs?
(I'm playing with waf, but I think the same issues would affect scons
and other build systems written in Python)
The issues I'd like to address are:
- bale out with sys.exit(1) is inappropriate except from main after
catching an exception
- there is no way to direct the generated files to a directory other
than the original source directory
Broadly I'd like to:
replace
print >>sys.stderr, 'foobar'
sys.exit(1)
with a throw of 'foobar' encapsulated, and mildly refactor Generate
so most of the code is in a function that receives the output filenames.
I'm slightly concerned about this code - it seems to me that the code
in Generate that deals with header files and implementation files
should be in the factory - its not appropriate in a PythonCodeGenerator
or JavaCodeGenerator for example. I think the factory should be
passed argv too (or asked what options it would like to process)
but that's a bigger task and I don't propose to attack that at the
moment.
Any comments?
James
