Asp Forum - convert YAML to HTML?

Rubies:

This has to have been on the YAML thought leader's Do List.

Is there a library, or a snippet, out there that converts YAML to esthetic,
meaningful XHTML?

I don't want to load the document into Ruby variables then stream them with
RedCloth because I'd lose the comments.

Can I load the comments, too, and stream everything?

Here's JB's Syntax module:

http://jamisbuck.org/jamis/blog.cgi/programming/ruby/Syntax%200.7_2005032...

Here's a sample output:

- [ formatWiki, this is ''em''phatic text, this
is emphatic text ]

That's not cute enough. It's essentially a syntax highlighter for YAML. (And
as such, it missed the [] tags and lexically significant commas , .)

I need <table> output with cute <tr><td> tags around the arrays. To use
Ruby's magical extensiveness on Jamis Buck's Syntax::Convertors::HTML class,
I would also need the lexer to parse [] and , properly.

I might just spark up a TDD session and see how far I get with app-specific
code...

Yes, it is not a complete YAML parser. A patch would be more than
welcome, though. If you (or anyone else) improves an existing lexer or
adds a new one, I would love to add your changes to the Syntax lib.

Puh-lease. Patches are so Last Millenium.

We shall do this via the most obnoxious implementation technique yet
discovered: Pair Programming Via USENET.

Here:

def test_list_of_lists
tok = []
@yaml.tokenize( "- [ foo ]" ) { |t| tok << t }
assert_equal [ :punct, "-" ], [ tok.first.group, tok.shift ]
assert_equal [ :normal, " " ], [ tok.first.group, tok.shift ]
assert_equal [ :punct, "[" ], [ tok.first.group, tok.shift ]
assert_equal [ :normal, " foo " ], [ tok.first.group, tok.shift ]
assert_equal [ :punct, "]" ], [ tok.first.group, tok.shift ]
end

I got each assertion working except the last, by adding this:

class YAML < Tokenizer
....
when scan(/:\w+/)
start_group :symbol, matched

when scan(/(\s*)\[/)
start_group :normal, subgroup(1)
start_group :punct, "["
....

However, now I can't find where to get the closing ] out of the :normal
string " foo ]".

After we do that, we need , working, and we need [ at BOL, without the -.

Thanks for the start on this, Philip. After taking what you did here
and working a bit more on it, I'm beginning to think what really needs
to happen is to rework the YAML lexer so that it uses a simple state
machine. That would give much more granular output. Also, where I've
been returning :normal (for "foo" in "bar: foo", for example), it
should probably be :string.

We could continue with the existing lexer, but I fear it will rapidly
become a case of plugging leaks and adding patch after patch...

I'll try to work on this some this afternoon, so the YAML lexer will be
a lot more robust.
