If you want to do this simply with just standard Python stuff you might try making template files that use the Python 3 style string formatting. For example, a class template might look something like this:

{className}::{className}()
{{
}}

{className}::~{className}()
{{
}}

{className}::{className}(const {className}& other)
{{
}}

{className}& {className}::operator=(const {className}& other)
{{
    return *this;
}}

Then your Python code is super simple:

d = {}
d['className'] = 'MyCPlusPlusClassName'
with open(yourTemplateFile, 'r') as ftemp:
    templateString = ftemp.read()
with open(generatedFile, 'w') as f:
    f.write(templateString.format(**d))

Of course you can add lots of other fields alongside 'className' using the same trick. If you don't need stuff like conditional code generation you can get a lot of mileage out of something this simple.

Let me explain a trick. Jinja2 is a template script that can generate text from templates. What you need to do is write your C code template main.c.j2:

#include <stdio.h>

int main()

{

    printf("hello {{name}}.\n");

    return 0;

}

then you can transform it into C code with the trans.py:

import os

from jinja2 import PackageLoader, Environment, FileSystemLoader



TemplateLoader = FileSystemLoader(os.path.abspath("."))

env = Environment(loader = TemplateLoader)



template = env.get_template("main.c.j2")



print(template.render(name = "Jack"))

run python trans.py and you will see this C code on screen:

#include <stdio.h>

int main()

{

    printf("hello Jack.\n");

    return 0;

}

That's real C code, {{name}} is replaced into Jack. See the Jinja2 doc for more interesting features.
