mdpad snippets and preview for the Atom editor

Here is an example of an mdpad file where both the live preview and snippets are used.

Live preview

The live preview is adapted from the atom-html-preview package.

The default key mapping to toggle the preview is ctrl-shift-j.

The preview updates whenever the mdpad file is saved.

Note that the live preview assumes that the base html file is named "mdpad.html". In the future, I may implement some way to customize that.

This generally works as well as using a local server along with a browser. One situation that doesn't work is with Modelica models compiled with Emscripten.

Also, note that in your mdpad.html file, all URLs must either be relative or direct. "Protocol-relative URLs" don't work. These are URLs that leave off http: or https:. This is also true of other resources like css files. For example, this css file includes a protocol-relative URL.

Another alternative to the live preview is to use Atom to start a server. The local-server-express package works nicely for this. Once launched, this will open a browser. Enter a url something like:

http://localhost:2000/mdpad.html?example.md

You can also use the Browser Plus package to load this right in Atom. With the live refresh feature, it works much like the Live Preview.

Snippets

The following snippets can help fill in mdpad blocks:

• js -- JavaScript block
• jsi -- JavaScript init block
• ya -- YAML block
• df -- dForm YAML block
• em -- Emblem block
• emn -- Emblem normal block

Inside dForm YAML blocks, several additional snippets are available:

• n -- Number form element
• s -- Select form element
• c -- Checkbox form element
• div -- div element
• row -- div row element
• col -- div col element

When in JavaScript blocks, all of the snippets from the language-javascript package are available.

Likewise, when in Emblem blocks, all of the snippets from the language-emblem package are available.
