Topdoc Comment Specification

Topdoc uses css-parse to divide asunder your css document and find all the relevant Topdoc comments.

Below is an example of a Topdoc comment, take a look, and then read the explanation under it.

/* topdoc
  name: Button
  description: A simple button
  modifiers:
    :active: Active state
    .is-active: Simulates an active state on mobile devices
    :disabled: Disabled state
    .is-disabled: Simulates a disabled state on mobile devices
  markup:
    <a class="topcoat-button">Button</a>
    <a class="topcoat-button is-active">Button</a>
    <a class="topcoat-button is-disabled">Button</a>
  example: http://codepen.io/
  tags:
    - desktop
    - light
    - mobile
    - button
    - quiet
  blarg: very true
*/
.topcoat-button,
.topcoat-button--quiet,
.topcoat-button--large,
.topcoat-button--large--quiet,
.topcoat-button--cta,
.topcoat-button--large--cta {
/* all your css junk here */

Topdoc comments must start with topdoc on the first comment line, it makes it quick and easy to identify from other comments.

The rest of the data uses a YAML friendly syntax.

The fields can be in any order, but this is a good example for consistency sake.

The following are recommend and/or required fields:

  • name (required): The full name of the component. Feel free to use spaces, punctuation, etc (name: Sir Button III, esq.)
  • description: Something more descriptive then the title alone.
  • modifiers: These can be psuedo classes, or addition rules applied to the component. This must be a YAML mapping (*modifier*:*description*) which becomes a js hash
  • markup (required): This is the magic; it's the html that will be used to display the component in the docs.
  • tags: Just some obligitory metadata.
  • blarg: Since Topdoc uses a flexible YAML syntax, feel free to add any additional custom data you might need for your template.

Topdoc assumes everything between two Topdoc comments, and everything after the last Topdoc comment, is a component. Put anything that isn't a component (general styles) above the first Topdoc comment.

Installation

Install with npm. It's meant to be command line tool, so you probably want to install it globally (with -g).

npm install -g topdoc

Help

The output of the help command.

-h, --help                                       output usage information
-s, --source <directory>                         The css source directory.
-d, --destination <directory>                    The destination directory where the usage guides will be written.
-t, --template <jade file/directory>             The path to the jade template file.  If it is a directory it will import all the sub files.
-p. --project <title>                            The title for your project.  Defaults to the directory name.
-V, --version                                    output the version number

Command Line Options

Source

Specify a source directory with -s or --source. Defaults to src/.

topdoc -s release/css/

Destination

Specify a destination with -d or --destination. Defaults to docs/.

topdoc -d topdocs/

Template

Specify a template with -t or --template. A default template is included in Topdoc if one is not provided.

The template can be a single jade file:

topdoc -t template/template.jade

or a directory (it will duplicate the whole template directory and look for index.jade in the template folder provided):

topdoc -t /template

This includes npm installed templates

topdoc -t node_modules/topdoc-theme

Project Title

The project title will be passed through to the jade template file.

topdoc -p Awesome

In the jade file it is project.title:

title=project.title

yeilds:

<title>Awesome</title>

package.json Configuration

All the options can be configured in the package.json file. This is super helpful if you are always using the same configuration. It will look in the package.json file if it exists, but can be overridden by the command line options.

Also, additional data can be passed through to the jade template. Below is an example:

{
  "name": "topcoat-test",
  "version": "0.4.1",
  "description": "CSS for clean and fast web apps",
  "main": "Gruntfile.js",
  "dependencies": {
    "topdoc": "0.0.12"
  },
  "topdoc": {
    "source": "release/css/",
    "destination": "topdocs/",
    "template": "node_modules/topdoc-theme",
    "templateData": {
      "title": "Topcoat",
      "subtitle": "CSS for clean and fast web apps",
      "download": {
        "url": "#",
        "label": "Download version 0.4"
        },
      "homeURL": "http://topcoat.io",
      "siteNav": [
        {
          "url": "http://www.garthdb.com", 
          "text": "Usage Guidelines"
        },
        {
          "url": "http://bench.topcoat.io/",
          "text": "Benchmarks"
        },
        {
          "url": "http://topcoat.io/blog",
          "text": "Blog"
        }
      ]
    }
  }
}

In the jade template the data is accessible using tesmplateData:

p=templateData.subtitle

yeilds:

<p>CSS for clean and fast web apps</p>

Template

The jade template has data passed through by default:

Document Object

The document object contains relevant information about just the current document being generated below is an example:

  "template": "lib/template.jade",
  "url": "index.html",

    },
    {
      "name": "Quiet Button",
      "slug": "quiet-button",
      "details": ":active - Quiet button active state\n.is-active - Simulates active state for a quiet button on touch interfaces\n:disabled - Disabled state\n.is-disabled - Simulates disabled state",
      "markup": "<a class=\"topcoat-button--quiet\">Button</a>\n<a class=\"topcoat-button--quiet is-active\">Button</a>\n<a class=\"topcoat-button--quiet is-disabled\">Button</a>",
      "css": ".topcoat-button--quiet {\n  background: transparent;\n  border: 1px solid transparent;\n  -webkit-box-shadow: none;\n  box-shadow: none;\n}\n.topcoat-button--quiet:active,\n.topcoat-button--quiet.is-active,\n.topcoat-button--large--quiet:active,\n.topcoat-button--large--quiet.is-active {\n  color: #c6c8c8;\n  text-shadow: 0 -1px rgba(0,0,0,0.69);\n  background-color: #404141;\n  border: 1px solid rgba(0,0,0,0.36);\n  -webkit-box-shadow: inset 0 1px rgba(0,0,0,0.18);\n  box-shadow: inset 0 1px rgba(0,0,0,0.18);\n}\n.topcoat-button--quiet:disabled,\n.topcoat-button--quiet.is-disabled {\n  opacity: 0.3;\n  cursor: default;\n  pointer-events: none;\n}\n"
    }
  ]
}

The nav object contains names and urls to all the generated html files. In the jade template this can utilized to create a navigation to the other pages.

nav.site: ul
    - each item in nav
        - if(item.url == document.url)
            li.selected: a(href=item.url)=item.text
        - else
            li: a(href=item.url)=item.text

Project Object

The project object contains relevant project information. Currently it only contains the title property. (passed through the command line -p option, or thorugh the package.json information).

title=project.title

TemplateData Object

As mentioned above, additional data can be passed through to the template in the package.json file. This is accessible in the template as the templateData object. See the example above.
