Background

I created this project because I felt all of the other "parse source-code comments to generate documentation" solutions were unsatisfactory for what I needed.

• Doxygen Is dated, obtuse, and its assumptions make it difficult to extend to languages without very C-like syntax.
• JavaDoc, JSDoc, or any other <LANGUAGE NAME>Doc-type solution are, obviously, limited to a single language; they can usually only produce opinionated HTML natively, relying on unmaintained third-party extensions to produce anything else; and they all have slightly unique syntaxes that are confusingly similar yet problematically different.
• Natural Docs Well definitely my favourite solution I've seen so far, its comment syntax is breezy and readable and it can easily be extended to any language, it still suffers from the issue of only natively producing HTML and its syntax can be pretty limited.

Plus, I found all of the documentation solutions above to be kind of poorly documented (with the possible exception of Natural Docs) which is kind of ironic ... so I decided to create my own ultra-minimalist solution to the "generate document from special source code comments" problem!

extract-documentation-comments does just that: it simply extracts any documentation between /** and */ lines in a source code file, or any input really. Why? Because:

• It's simple stupid: can easily be modified or extended to any specific use case.
• It makes zero assumptions about the text between the /** and */ so you're free to markup the text in any way you want; Markdown, reStructuredText, XML, whatever and convert it to what you need after the fact. I recommend PanDoc for this.
• It can easily be finagled to be backwards compatible with any existing source-code documenting solution.

Install

Using pnpm:

pnpm add --save extract-documentation-comments

It can, of course, also be installed by npm or Yarn using the normal methods.

Usage

To use the command-line interface pnpm extract-documentation-comments or just extract-documentation-comments if installed globally.

CLI

extract-documentation-comments

                             this option, doing so will activate multi-file mode: in this mode,            
                             `--output` must also be used and given the name of the directory place the

  -O, --output string        The name of the file to write output to or, in the case of us passing         
                             multiple paths to `--input`, the name of the directory to place the generated 
                             documentation files.
