Default code-prettify highlighting for C# is incorrect

Question

Recently I had quite a few edits to include the correct syntax-highlighting for C# questions:

<!-- language: lang-csharp -->

That's needless editing for a thing that could also be done via machine.

I suggest defaulting to lang-csharp for questions asked with c#.

Update:

Example question:

• Solving for the zero of an arbitrary function

The above question highlights differently with lang-cs vs. lang-csharp (with lang-csharp being superior).

Issues:

1. lang-csharp is not documented to exist
2. it is not available in the tag-wiki syntax editor

Answer 1

I looked into what does the SE version of prettify.js actually do. Turns out, its list of C# keywords starts like this (only with minified names):

var CSHARP_KEYWORDS = [JAVA_KEYWORDS,
  "as,base,by,checked,decimal,delegate,descending,dynamic,event," + …

This list is from an old version of prettify, the current version starts like this (the relevant change was made in June 2013):

var CSHARP_KEYWORDS = [COMMON_KEYWORDS,
  "abstract,as,base,bool,by,byte,checked,decimal,delegate,descending," + …

The reason why lang-csharp looks like it works, is because that's considered an unknown language and so it uses ALL_KEYWORDS, which includes bool through CPP_KEYWORDS. This also means that something like lang-nonsense would have worked the same way.

The fix should be to make SE update prettify to its current version.

Answer 2

lang-csharp is not available as a syntax for tags:

The current language for c# is lang-cs which is.... from here: C# ...

Are you sure you have the syntax right?
