pwcp

Python with C preprocessor

Installation

pip install pwcp

Running

pwcp <file>

pwcp -m <module>

Or run built-in code module to start interactive console:

pwcp -m code

Run pwcp -h for more options.

Why?

For fun! And for YABI.

How to use it?

The extension for files that need to be preprocessed is .ppy (pre-python). You can start by creating hello.ppy and putting there something like

#define hello "Hello "
#define world "world!"
print(hello world)

Then run it

~ $ pwcp hello.ppy
Hello world!

Congratulations! You've run your first program with PWCP.

Extension for header files?

Suggested extension is .pyh (python header), but technically you can use whatever you like.

What about comments?

The suggested way to write comments in .ppy (and .pyh) files is /* comment */

// is not a comment as it's floor division in Python and # indicates preprocessor directives.

Does it work with pure Python?

Of course. It works like an extension allowing you to run and import .ppy files. You can import .ppy file in .py file and vice versa.

Feel free to submit an issue if something doesn't work.
