CodeGen

Generate C source code in a more structured way that raw string manipulation. Works great with Ned Batchelder's CogApp.(link)

Features

• Supports many C constructs
• Formatting via clang-format(must have clang-format installed, obviously!)

Supported C constructs

• types (only some)
• variables
• functions
• enums
• structs
• header files

Requirements

Codegen uses clang-format to clean up its output

Installation

git clone https://github.com/DaelonSuzuka/CodeGen.git
cd CodeGen
pip install .

Example

>>> import codegen as code

Let's create the simplest possible function:

>>> code.format(code.function())
'void func(void);'

Valid, but not terribly useful.

We need to at least give it a name:

>>> code.format(code.function('test')) 
'void test(void);'
>>> code.format(code.function(name='test2')) 
'void test2(void);'

Alright, now how about some parameters or a return type?

>>> code.format(code.function('test', params=['int x', 'bool y']))
'void test(int x, bool y);'
>>> code.format(code.function('test2', ret='bool'))
'bool test2(void);'

But wait, these have all been function declarations. How do we make a definition?

>>> code.format(code.function('test', body=['// this is a comment', 'foo();']))
'void test(void) {\n  // this is a comment\n  foo();\n}'

That's not quite right, let's try that again:

>>> print(code.format(code.function('test', body=['// this is a comment', 'foo();']))) 
void test(void) {
  // this is a comment
  foo();
}

Much better!
