Syntax highlighting for files (and diffs?)

[rtyley]

For presenting blobs, gists, etc we need syntax highlighting...

a) use a WebView (the Android Gmail app renders mail messages using a web view) with a syntax-highlighting JavaScript lib. There are lots of these:

http://shjs.sourceforge.net/
https://github.com/alexgorbatchev/SyntaxHighlighter
https://github.com/isagalaev/highlight.js
http://code.google.com/p/google-code-prettify/
http://ace.ajax.org/ - also a code editor...

b) use a Java highlighting library, but there don't seem to be many maintained libraries around:

http://code.google.com/p/jsyntaxpane/
source-grab from Eclipse or Intellij?

Diffs: Of course, personally I'm in love with animated diffs, and it might be hard to combine the animated diff approach with syntax highlighting - maybe only show plain-black-text during transition...

After an initial look I think I'm leaning towards shjs with sunburst theme shown here.

That example renders well on my android browser, very nice. Worth noting that shjs is GPLv3.

Good point, I made a commit that uses google-code-prettify (apache licensed) in the gist source viewer.

We can play around and tweak it for now and see how it goes

Switched to using SyntaxHighlighter as it supports more languages and has a line number column.

The downside is where google-code-prettify sniffs for the language, you have to be explicit with SyntaxHighlighter
which adds a bit of gnarly code in Java to ensure that a highlighter brush is always applied.

Closing now, may revisit if a better solution is found.
