indoc v0.4.19

Inline documentation generator for complete projects

inline documentation generator

Inspired heavily by docco, indoc is a quick-and-dirty documentation generator written in plain JavaScript. It can be run either from the command line or included as a node.js library.

Unlike docco, indoc has the concept of a project; instead of having a hacky "Jump To" menu, indoc has an integrated file listing on each generated page. (Check it out on the left.)

The recommended usage is to install indoc globally and use a local project config file with the -c command line option.

$ ls
bin/     lib/     src/     README.md   indoc.json
$ more indoc.json
{
  "name": "Mousetrap Simulation Library"
  "owners": "Tom",
  "output": "docs",
  "readme": "README.md",
  "version": "package.json",
  "files": [
    "src/**/*.js"
  ]
}
$ indoc -c indoc.json
info: Generated "README.md"
info: Generated "src/animal.js"
info: Generated "src/cat.js"
info: Generated "src/mouse.js"
info: Generated "src/trap.js"
info: Successfully generated 5 files
$ ls
bin/     docs/    lib/     src/     README.md   indoc.json
$ ls docs/
index.html README.md/    animal.js/    cat.js/    mouse.js/     trap.js/
$ 

Getting the library

npm install -g indoc

The command indoc should now be available.

Alternatively, use

npm install indoc

to use the library as a node.js module.

Using the command line program

$ indoc [options] files...

-c <config> or --config <config>

Sets a config file to read configuration options from. If used, the rest of the arguments are ignored.

Example config file:

{
  "name": "Mousetrap Simulation Library"
  "owners": "Tom",
  "output": "docs",
  "readme": "README.md",
  "version": "package.json",
  "files": [
    "src/animal.js",
    "src/cat.js",
    "src/mouse.js",
    "src/trap.js"
  ]
}

-h or --help

Displays help. If you need to consult the README to find this argument, you shouldn't be using indoc in the first place.

-v or --version

Displays the program's semver; for example, 0.1.0, then exits.

$ indoc --version
0.3.2
$

-r <file> or --readme <file>

Provide a README file, to be used on the project's overview page. This file will be parsed as Markdown.

-n <name> or --name <name>

Set the user-facing name of the project.

-o <directory> or --output <directory>

Set the output directory (the default is docs).

--owners <owners>

Sets a string. By default, it's contributors. This string is at the footer of every generated page.

-p <version> or --project-version <version>

Sets the project version. This is displayed on every page. The special string package.json will attempt to read the package.json file and find the version there.

Using the library

var indoc = require('indoc');

var project = new indoc.Project({
  name: 'Mousetrap Simulation Library',
  owners: 'Tom', // "Copyright 2016 Tom"
  output: 'docs',
  readme: 'README.md',
  version: 'package.json', // the special string "package.json" will open the file "package.json" and read the version string there
  links: {
    github: "https://github.com/tom/mousetrap-sim",
    twitter: "https://twitter.com/mousetrapsim"
  },
  files: [
    'src/animal.js',
    'src/cat.js',
    'src/mouse.js',
    'src/trap.js'
  ]
});

project.run(function(err, data) {
  console.log('Generated ' + data.total + ' files!');
});

External Project Links

You can reference external links with the links key in options. Currently supported link types are:

  • github
  • twitter
  • home

Languages

The languages supported by indoc are stored in lib/languages.json in the following format:

"JSFOO": {
  "extensions": [
    "js", "json"
  ],
  "name": {
    "hljs": "JavaScript",  // the language type for Highlight.js, 'auto' to autodetect, or `null` for Markdown
    "human": "JavaScript", // the human-readable language name. If not present, the name of the language
                           // (JSFOO, above) is used instead.
    "abbr": "JS"           // The short abbreviation of the language. If not present, the first item in
                           // "extensions", above, is used.
  },
  "single": [ "//", ";;" ],
  "multi": [
    ["/*", "*", "*/"]
  ],
  "ignore": [
    "eslint-disable"
  ]
}

Right now, if there's a language that's not included or not set up to your liking, you can use the languages field of the options argument of the indoc.project to add new languages or modify existing ones:

var project = new indoc.Project({
  name: 'Mousetrap Simulation Library',

  ...

  files: [ ... ],
  languages: {
    'SubScript': {
      extensions: [
        'sub', 'sbs'
      ],
      name: {
        hljs: 'JavaScript', // the language type for Highlight.js, or null
        human: 'JavaScript',
        abbr: 'JS'
      },
      single: [ '//', ';;' ], // a single-line comment starts with '//' or ';;'
      multi: [
        ['/*', '*', '*/'] /* See below for an explanation of how multiline comments work. */
      ],
      ignore: [
        'hideme!' // hideme! (this comment will be ignored)
      ]
    }
  }
  });
  
  /* a multi-line comment starts with '/*' and ends with '*/'.
  * Optionally, if a line starts with '*', it will be removed
  * to allow for indented multi-line comments, like this one.
  * Both `single` and `multi` allow for multiple comment formats.
  * */

Contributing/Feedback

At the moment, indoc is very, very new. It would probably be better if, instead of contributing code, you open new issues. I'd like to see indoc stabilize more before changing major areas of its functionality.

Contributing languages

Just edit lib/languages.json and open a PR with the languages you've included. Make sure that the JSON still validates and that indoc runs without any problems. Thanks!
