Readable text to HTML markup language

Rimu Markup

Rimu is a readable-text to HTML markup language inspired by AsciiDoc and Markdown.

Features summary

  • Markup generation can be customized and extended.
  • Includes a simple, flexible macro language.
  • HTML attribute injection and parametrized macros.
  • Accepts raw HTML (a la Markdown).
  • A subset of the Rimu syntax is Markdown compatible.
  • One-function API.
  • Playground GUI, Vim syntax highlighter and a unit test suite.
  • MIT license.
  • Ported to three language platforms:
    • The canonical JavaScript version written in TypeScript with no dependencies. Single JavaScript file (less than 22KB minified) that can be dropped onto a Web page or used as a Node module.
    • A Kotlin port for the JVM platform.
    • A Go port.

Quick start

To try the Rimu library in your browser:

  1. Open the Rimu NPM Runkit page in your browser.
  2. Paste in this code then press the Run button.
var rimu = require("rimu")
var html = rimu.render('Hello *Rimu*!')

This will output "<p>Hello <em>Rimu</em>!</p>".

Installing Rimu

Install Rimu as a Node.js module (includes the rimu library and the rimuc command-line tool):

    sudo npm install -g rimu

Run a simple test from the command prompt to check rimuc is working:

    echo 'Hello *Rimu*!' | rimuc

This should output:

    <p>Hello <em>Rimu</em>!</p>

  1. Install the Git repository from Github.
