Asp Forum - JavaScript-based Ruby lexer/parser for CSS syntax highlighting?

Gavin Kistner

I'm looking for a JS library that will find <code class="ruby"> (or
otherwise-specified) elements on an HTML page and wrap bits in <span
class="keyword">...</span> type elements for CSS syntax coloring of
the original source.

I've found two JS-based syntax highlighters ([1] and [2]), but both
fail on Ruby code like:
foo = "Hello #{ "World" }"

They're both regexp-based, which is the problem. I'm happy to use them
for quick-n-dirty highlighting, but I'm hoping that someone has
written a lexer/parser that handles more complex situations like this
(even if it doesn't cover every single edge case).

Does it have to be JS? You gonna do client side lexing of ruby in JS? (I
guess it has to be, else you wouldn't have asked.)

Sure you can't use http://coderay.ru... instead?

I could, for sure. That trades bytes over the wire for user's cpu
time. Sometimes I just really like having code syntax highlighted by
the page, particularly when it's a tiny snippet as part of a larger
page, and not an entire source file.

I hacked the second library I found to do what I want. Although I'm
annoyed with its speed, it's working reasonably OK for now. It looks
like I was wrong, that is has some form of 'real' lexing applied via a
very incomplete idea about Ruby syntax. If no one has a premade JS
library for this, and if it bothers me enough, I'll spend some time
understanding its scoping and lexing rules and see if it can make the
jump from string mode back into code mode. My quick hackery to add
some features makes it look possible.

Put some quoting characters or indentation characters around text you
quote.

You're post makes it look like you are argueing with yourself.

While I agree that all gods are equally valid, the Buddha never claimed
to be a god. He had 'Godness' thrust upon him by men.

And by equally valid, I mean that there is no evidence for any of them.
Ergo, their validity is equally meaningless.

Don't they all?

That's what I was trying to say.
Sorry you missed the implication of my statement.

I never said he was a god.

I said "the Buddha's words and deeds are pure."

I also said I follow Buddha and not YAHWEH.

Why do you make a moot point in saying Buddha was not a god? I never
claimed he was.
