# cwriter

# Project Description
The package facilitates the creation of C (.h) files from Python. It's not designed to generate every possible C file or cover the entire C syntax. Rather, its primary focus is to generate files that contain elements like arrays or strings as well as constants, defines, and typedefs that can be imported from other sources or linked into a project.

# Example

This code

```python
    numbers = list(range(100))

    f = CFile("example.h")

    f.openGuard()
    f.define("THIS", 0)
    f.newLine()
    f.comment("A variable definition with intialization")
    an = {5: "This is an annotation for the element at position 5", 30: ("Another annotation, but with single=True for the element at position 30", True)}
    f.varDefinition("const int[]", "values", numbers, to_str_fn=paddedHex(2), annotations=an)
    f.newLine(2)
    f.comment("A variable declaration")
    f.varDeclaration("const int", "size", extern=True)
    f.newLine()
    f.varDeclaration("const int[]", "values")
    f.newLine()

    f.comment(["Now a multilne", "comment", "here"])
    f.newLine()
    f.comment("Another comment with a backslash at the end (note the added dot) -> \\")
    f.newLine()
    f.comment("Another array")
    f.varDefinition("const char[]", "other", [1, 2, 3, 4, 5])
    f.comment("A variable definition, with extra attributes")
    f.varDefinition(["const", "char[]"],
                    "var_name", "this is a string",
                    extra_attribs="__attribute__ ((aligned (16)))")
    f.closeGuard()

    f.print()
    f.write()

```
