Mediawiki RawFile

Introduction

The idea is to be able to download directly a portion of code as a file.
I've numerous code examples in my wiki and I wast an easy way to download them, easier than a copy/paste!

• It must work with pre, nowiki, js, css, code, source, so let's make it general: take the tag that comes after the parser function we'll create and select data up to the closing tag.

2 parts:

• the parser magic word that will be converted into a "Save it as <filename>"
• an extended action=raw that will strip the raw output to keep the desired code

Syntax

{{#rawsnippet: myscript.sh}}
Do we need a MIME type?
Transformation:
{{fullurl:{{PAGENAME}}|action=raw&rawsnippet=myscript.sh}}
Test: save the following code [{{#rawsnippet: myscript.sh}} as myscript.sh]

#!/bin/bash

echo 'Hello world!'
exit 0

{{#rawsnippet: myscript.sh}} combines in fact 2 elements: the text that will be replaced by the link and the anchor just before the code section.
We can separate both functionalities with:

One such declaration, just before the code section: {{#rawsnippetAnchor: myscript.sh}}

One or many such declarations to create the download links: {{#rawsnippetLink: myscript.sh}}

Hook on Raw

• Must extract the right paragraph
  • Strip all up to the right rawsnippet: filename tag
  • Find the next tag
  • Select up to the closure tag
• Must provide the filename to the browser
• Tells the browser NOT to cache the raw?
