Using lang-cs doesn't highlight the keywords `namespace` and `using` #299

Open GoogleCodeExporter opened 9 years ago

I found that this isn't highlighting the keywords 'namespace' and 'using' with 
the default highlighting or the 'lang-cs' tag. But it works when using 
'lang-csharp' which isn't mentioned in your README.

I had originally thought that it's the error in SO but it's not being detected 
in my own html file as well. See the original topic at

The original problem is identified in that thread. The C# keywords list is 
missing keywords 'namespace' 'using' and 'get'

This related to issue #283. Currently [the code][1] tries to reduce repetition
by having a list of common keywords and inheriting this list from the various
languages. Unfortunately, a couple of extra keywords slip through, as well as 
missing a few specific ones.

I went through this [list][2], and came up with the following (basically I 
"unrolled" the list of inherited keywords and removed the extra tokens, while 
adding a few missing ones):

  var CSHARP_KEYWORDS = [FLOW_CONTROL_KEYWORDS,

      "case,char,const,default," + 
      "double,enum,extern,float,goto,int,long,short," +
      "sizeof,static,struct,switch,void,volatile," +

      "catch,class,false," +
      "new,operator,private,protected,public,this,throw,true,try,typeof," +

      "abstract,as,base,bool,byte,checked,decimal,delegate,descending," +
      "dynamic,event,finally,fixed,foreach,from,group,implicit,in,interface," +
      "internal,into,is,let,lock,null,object,out,override,orderby,params," +
      "partial,readonly,ref,sbyte,sealed,stackalloc,string,select,uint,ulong," +
      "unchecked,unsafe,ushort,var,virtual,where," +

      "ascending,async,await,explicit,get,global,join,namespace,set,using,yield"];

This should fix the case of the missing keywords you mentioned, along with a 
few others. Note that C# has some contextual keywords, meaning that the token 
is only considered in certain contexts, which is not possible without a proper 
grammatical parsing.

btw, Stack Overflow is apparently not using the latest version of 
code-prettify, so it might take some time for you to see the changes over 
there..
