documentation-polyglot.js

The documentation system for modern JavaScript

When good engineers meet, they discuss algorithms, but when great engineers meet, they discuss documentation

Plugin Notes

This plugin restores the C++ support for documentation.js.

It requires a plugin framework in documentation.js that has yet to be merged. You can install it from here:

npm install -D @mmomtchev/documentation

It is an improved version of the old --polyglot CLI option of documentation.js that got axed in 2017.

The project should already be usable.

It uses dumb parsing without an AST blindly extracting JSDoc-compliant comment blocks.

I intend to add extensible helpers allowing to extract some (C++ is notoriously difficult to parse and this aims to be an universal extractor anyways) information from the C++ code.

Installation

The module is not yet published

npm install -D documentation-polyglot

Usage

Note that enabling documentation-polyglot will also enable --shallow if this is not already the case.

Loading via the command-line

documentation build --plugin=documentation-polyglot src/*.cpp lib/*.js -f md -o project.md

Loading via a configuration file

documentation build --config=project-documentation.yml src/*.cpp lib/*.js -f md -o project.md

project-documentation.yml:

toc:
  - Project Headline

Extracting information from C++ code

An example for extracting names of Node::Nan methods

documentation-polyglot:
  extensions: [ .cpp ]
  infer:
    kind:
      function: [ NAN_METHOD\(.*\) ]
    name: [ NAN_METHOD\s*\((.*)\) ]

An infer section applies an implicit JSDoc tag to the tag having the section name:

• with subsections it will apply the subsection name when one of the provided REs matches.
• with only REs it will apply the first capture group
