markdown-it-wikirefs v0.0.3

markdown-it-wikirefs

A markdown-it plugin to process [wikirefs].

Note that this plugin only parses the input -- it is up to you to assign appropriate linking information and/or index relationships (between files).

Install

Install with npm:

$ npm install markdown-it-wikirefs

Use

import markdownIt from 'markdown-it';
import wikirefs_plugin from 'markdown-it-wikirefs';

const md = markdownIt();
const options = {
  resolveHtmlHref: (env: any, fname: string) => {
    const extname: string = wikirefs.isMedia(fname) ? path.extname(fname) : '';
    fname = fname.replace(extname, '');
    return '/' + fname.trim().toLowerCase().replace(/ /g, '-').replace(/[^\w-]+/g, '') + extname;
  },
  resolveHtmlText: (env: any, fname: string) => fname.replace(/-/g, ' '),
  resolveEmbedContent: (env: any, fname: string) => fname + ' content',
};
md.use(wikirefs_plugin, options);
md.render('[[wikilink]]');

Require style imports work as well:

const wikirefs_plugin = require('markdown-it-wikirefs');

// if you encounter issues, try:
const wikirefs_plugin = require('markdown-it-wikirefs').default;

Syntax

For syntax specifications, see the wikirefs repo.

Option recommendations

For render output:

• resolveHtmlText
• resolveHtmlHref
• resolveEmbedContent

For wikiembeds -- note:

• path.extname(filename) is used to identify the file extension which determines how the embed should be formatted.
• Check for self-references and cycles when defining opts.resolveEmbedContent().

For metadata population:

• addAttr
• addLink
• addEmbed
• prepFile (useful for clearing a cache for the current markdown file per render)

Options

addAttr: (env: any, attrtype: string, fname: string) => void

addLink: (env: any, linktype: string, fname: string) => void

addEmbed: (env: any, fname: string) => void

attrs

These are options wikiattrs-specific options. If markdown-it-wikirefs is being used in conjunction with markdown-it-caml, attrs options may be set in markdown-it-caml and will apply to markdown-it-wikirefs as well.

attrs.enable

A boolean property that toggles parsing and rendering wikiattrs on/off.

attrs.render

A boolean property that toggles rendering wikiattrs on/off. This is useful in the scenario where wikiattrs are used for metadata and not for display purposes; like a yaml-stand-in.

attrs.title

A string to be rendered in the wikiattrs' attrbox.

baseUrl

A base url that is applied to all urls internally.

cssNames

CSS classnames may be overridden here.

cssNames.attr

Classname for wikiattrs. Default is attr.

cssNames.link

Classname for wikilinks. Default is link.

cssNames.type

Classname for typed wikilinks. Default is type.

cssNames.wiki

Classname for valid wikirefs. Default is wiki.

cssNames.invalid

Classname for invalid wikirefs. Default is invalid.

cssNames.reftype

Classname for wikiref type. Default is reftype__ and combined with the slugified form of the user-defined reftype.

cssNames.doctype

Classname for document type. Default is doctype__ and combined with the slugified form of the user-defined doctype.

cssNames.attrbox

Classname for the wikiattr attrbox. Default is attrbox.

cssNames.attrboxTitle

Classname for the wikiattr attrbox title. Default is attrbox-title.

links

These are options wikilinks-specific options.

links.enable

A boolean property that toggles parsing/rendering wikilinks on/off.

prepFile: (env: any) => void

resolveDocType: (env: any, fname: string) => string | undefined

A function which takes in markdown-it's env var and the fname extracted from a wikilink [[fname]]. It should return a string which is the name of the file's document type or undefined if no document type exists. (Relevant file data should be stored in env, but if not fname can be used to search for the file instead.)

resolveEmbedContent: (env: any, fname: string) => string | undefined

A function which takes in markdown-it's env var and the fname extracted from a wikilink [[fname]]. It should return the content of an embedded markdown file. Be sure to handle self references and cycles with care when re-using the markdown-it instance to re-render content (e.g. md.render(content)).

resolveHtmlHref: (env: any, fname: string) => string | undefined

A function which takes in markdown-it's env var and the fname extracted from a wikilink [[fname]]. It should return the url of the wikilink-ed file or undefined if no such file exists. If no such file exists, the wikilink will render as disabled and marked as invalid. (Relevant file data should be stored in env, but if not fname can be used to search for the file instead.)

It is recommended to override the default, but there is a default returns: '/' + fname.trim().toLowerCase().replace(/ /g, '-').replace(/[^\w-]+/g, '').

resolveHtmlText: (env: any, fname: string) => string | undefined

A function which takes in markdown-it's env var and the fname extracted from a wikilink [[fname]]. It should return a string representing the text to populate the a tag's innertext of the wikilink-ed file -- this is often its title -- or undefined if no such file exists. If no such file exists, the filename will be used to populate innertext instead. Be sure to apply any text formatting such as lower-casing here. (Relevant file data should be stored in env, but if not fname can be used to search for the file instead.)

It is recommended to override the default, but there is a default which returns: fname.replace('-', ' ').
