Haskell identifies

[GoogleCodeExporter]

What steps will reproduce the problem?
1. open this URL:
<http://code.google.com/p/omega/source/browse/branches/llvm-gen/GenLLVM.hs?r=86#
78>
2. look at the selected line
3. it appears starnge

(Please include HTML, not just your source code)


What is the expected output?  What do you see instead?

In Haskell the apostrophe character can be tacked behind identifiers,
like

a' = 42;
b'' = 25;

Your highlighting code does not seem to cope with this :-(
and treats it like the start of a literal character constant.

What version are you using?  On what browser?
the version in google hosting, see
<http://code.google.com/p/support/issues/detail?id=709>

Safari 3.0 browser.

the subject should be

"Haskell identifiers with apostrophe highlighted wrongly"

but I pressed the return key before that.

also, the "--"-style comments are not recognized.
these are similar to the C++ "//"-style comments, but must be preceded by a 
blank

feel free to contact me about the exact rules

Is haskell's lexical grammar similar enough to LISP's that the new lisp mode at
http://google-code-prettify.googlecode.com/svn/trunk/tests/prettify_test.html#is
sue42
would work as a basis?

Unfortunately not, Haskell has a more complicated syntax, as
it is indentation dependent (with offside rule) resembling Python,
and not easy to parse.

But the bug itself is easy to fix IMHO :-)
