C/C++ Header to Markdown converter (mdcdoc)

Small utility for generating markdown file from block comments in C/C++ source code.

library.h  →  [mdcdoc]  →  documentation.md

Basic idea is that you already have markdown text in block comment of your code and you want to take them into separate file.

Use the JavaDoc syntax for proper functioning

Sample Comment

Input

/**
 * # Constructor
 */

/**
  * Constructor for the Dummy class
  * @param foo this is foo
  * @param bar this is bar
  * @return new `Dummy` object
  */

Output

---

💡 Dummy(uint8_t foo, uint8_t bar)

Constructor for the Dummy class

Dummy(uint8_t foo, uint8_t bar)

Params:

• foo - this is foo
• bar - this is bar

Returns:

• new Dummy object

Examples

• timer.h → timer.md (C++ header)
• simple.h → simple.md (C header)

Usage

Get application. Requires node.js and npm to be installed on computer.

Use npx if you don't want to store the package locally.

npx mdcdoc -p cpp -o documentation.md library.h
                            ↑             ↑
                       destination     header file

Theory of operation

mdcdoc works in 3 steps:

1. Take block comment (beginning with /**) from file plus one following line of code.
2. Apply patterns to block according to that one line of code (if not empty). Patterns are in libs.
3. Go block by block and
   • If code line is empty, just put content of block to output file.
   • If code line is not empty, make md header from it and then put content of block.
