doconce/preprocess

C/C++ preprocessor-like tool for a range of languages (i.e., #ifdef, #ifndef, #if-else, #include, etc. for Python, LaTeX, Bash, JavaScript, "whatever").

preprocess's Issues

Do you still need to support for Python 2

This project depends on future to provide some pieces of Python 2 support. The problem is that future is broken with Python 3.12 and will stop working completely with Python 3.13. Therefore it'd be good to remove the dependency and either drop Python 2 support as well or find another way to provide it. It should not be hard and I can help with that.

Regression with #include and -I option

After having some spare time to resurrect a personal project of mine which uses preprocess, I upgraded from v1.1.0 to v1.2.3.

Found a regression with #include statements and providing include paths with the -I command-line option, whereby preprocess is no longer able to find the #include'd file in any of the include paths provided. Preprocess errors out with a message similar to the following:

preprocess: error: could not find #include'd file "c.p.txt" on include path: ['include']

Steps to reproduce:

1. Create a.p.txt to have the following content:

BEFORE include
# #include "b.p.txt"
AFTER include

2. Create includes/b.p.txt to have the following content:

DURING include

3. Run preprocess from in the same directory as a.p.txt: preprocess -I includes a.p.txt
4. Observed output:

BEFORE include
preprocess: error: could not find #include'd file "b.p.txt" on include path: ['includes']

5. Expected output:

BEFORE include
DURING include
AFTER include

I believe the regression appeared in commit e937b3b where the else: raise statements were indented from the matching for statement to the matching if statement:

preprocess/lib/preprocess.py

Lines 497 to 504 in e937b3b

	for d in [os.path.dirname(infile)] + includePath:
	fname = os.path.normpath(os.path.join(d, f))
	if os.path.exists(fname):
	break
	else:
	raise PreprocessError("could not find #include'd file "\
	"\"%s\" on include path: %r"\
	% (f, includePath))

Put this version of preprocess on Pypi

Please put this version on Pypi. It would solve issues that I ran into today that prevented me from installing doconce:
