Flatworm Docs

The Flatworm Docs rendering script is designed to be very simple, but provide enough formatting necessary for documenting JavaScript libraries.

A lot of its inspiration came from Read the Docs and the Sphinx project.

##
Fragments

Flatworm Docs are made up of fragments. A fragment is either a lone body of markdown text, or a directive for specialized formatting, which may itself have body.

###
Directive Format

_DIRECTIVE: VALUE @<LINK> @META<PARAMETER>
BODY
DIRECTIVE: The directive name
VALUE: Optional; the value to pass to the directive
LINK: Optional; a name for internal linking
META: Optional; extended directive functionality
PARAMETER: Optional; value to pass to extended directive functions
BODY: Optional; the directive body (certain directives only)

###
Flatworm Directives

_section: TITLE

A section has its TITLE in an H1 font. Sections are linked to in Table of Contents and have a dividing line drawn above them. If an option is specified, it is avaialble as a name for intern linking. There should only be one `_section:` per page.

_subsection: TITLE

A subsection has its TITLE in an H2 font. Subsections are linked to in Table of Contents and have a dividing line drawn above them. If an option is specified, it is avaialble as a name for internal linking.

_heading: TITLE

A heading has its TITLE in an H3 font. If an option is specified, it is available as a name for internal linking.

_definition: TERM

A definition has its TERM bolded and the markdown body is indented.

_property: SIGNATURE

A property has its JavaScript SIGNATURE formatted and the markdown body is indented.

_note: TITLE

A note is placed in a blue bordered-box to draw attention to it.

_warning: TITLE

A warning is placed in an orange bordered-box to draw attention to it.

_code: FILENAME

A code reads the FILENAME and depending on the extension adjusts it.

For JavaScript files, the file is executed, with `//!` replaced with the result of the last statement and `//!error` is replaced with the throw error. If the error state does not agree, rendering fails.

_toc:

A toc injects a Table of Contents, loading each line of the body as a filename and recursively loads the toc if present, otherwise all the sections and subsections.

_null:

A null is used to terminated a directive. For example, after a definition, the bodies are indented, so a null can be used to reset the indentation.

###
Examples

_section: Hello World @<link-to-this-section>
_subsection: Some Example @<link-to-this-subsection>
_heading: Large Bold Text @<link-to-this-heading>
_definition: Flatworm
A phylum of relatively **simple** bilaterian, unsegmented,
soft-bodied invertebrates.
_property: String.fromCharCode(code) => string
Returns a string created from //code//, a sequence of
UTF-16 code units.
_code: filename.js
_toc:
some-file
some-directory
_definition and reset the indentation.
_note: Title
This is placed in a blue box.
_warning: Title
This is placed in an orange box.
_null:
This breaks out of a directive. For example, to end a

##
Markdown

The markdown is simple and does not have the flexibility of other dialects, but allows for bold, italic, underlined, `monospaced`, super-scripted text, supporting links and lists.

**bold text**
//italic text//
__underlined text__
``monospace code``
^^superscript text^^
- This is a list
- With bullet points
- With a total of three items
This is separated by -- an en-dash.
This is separated by --- an em-dash.
This is a [Link to Ethereum](https://ethereum.org) and this
is an [Internal Link](some-link).
This is a self-titled link [[https://ethereumorg]] and this
[[some-link]] will use the title from its directives value.

##
Configuration

Configuration is optional (but highly recommended) and may be either a simple JSON file (config.json) or a JS file (config.js) placed in the top of the source folder.

TODO: example JSON and example JS
