JavaScript library for syntax highlighting for code, then diffs, in HTML, at the line level? -

-

anyone know of js library allow me syntax highlight code block, highlight line-level diffs? example, in subversion diff, i'd highlight characters on line have changed (as highlighting fact there change(s) on line).

edit: i'm after let me syntax highlight according language, syntax highlight fact it's diff, , ideally, on top, highlight changed-characters on lines have changed. saw gallio not-equal assertion-exceptions, haven't looked @ yet.

the google syntax highlighter great, , supports lots of languages. i'm not sure if supports diffs though, think it's quite extensible.

i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
