syntax highlighting is incorrect

[nf]

String literals are highlighted in green. Keywords and some pre-declared identifiers are reddish. The issue I have is with the "some". Highlighting should be consistent.

Here is the list of predeclared identifiers from the spec:
http://golang.org/ref/spec#Predeclared_identifiers
And keywords:
http://golang.org/ref/spec#Keywords

I suggest that either pre-declared identifiers should not be highlighted at all (as they may be shadowed by some other declaration), or that they should all be highlighted in a different color to keywords.

Yep I agree that consistency would be good, thanks for the report @nf.

To start I changed the toolchain to use the most recent version of Pgyments, which has helped some. In particular more tokens including boolean constants and previously-unrecognized predclareds are now recognized. There is a tradeoff now between having a different color for everything and having too many colors. I'm not thrilled about the current scheme but I think it's correctness is strictly better than the previous version.

I'll leave the issue open while we continue to think about this.

@nf
I"ve use pygment to generate to dlin.github.com/gobyexample, please check if it correct for you.

@dlintw I guess it's okay. The distinction between pre-declared identifiers (int, string) and keywords (func, var) isn't very strong int hat case, though.

Well, I don't want to deep into modify this problem, just call the system pygment. If there is good Go library, maybe I'll learn how to put it in.
