The body id generated in header.html.tmpl from the urlbase para on my site includes a tilde tilde (~); see: http://www.async.com.br/~kiko/mybugzilla/show_bug.cgi?id=3 You'll find: id="www-async-com-br-~kiko-mybugzilla" This fails HTML4 validation: http://validator.w3.org/check?uri=http://www.async.com.br/~kiko/mybugzilla/show_bug.cgi?id=3 Line 45, column 24: character "~" is not allowed in the value of attribute "ID" From the spec: id = name [CS] This attribute assigns a name to an element. This name must be unique in a document. ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods ("."). Sounds like some filtering is in order; at least something less hackish than the current Param('urlbase').replace('^https?://','').replace('/$','').replace('[@:/.]','-') Any ideas?
There's a css_class_quote filter in Util.pm which should do the job. Gerv
css_class_quoting produces: id="www-async-com-br-~kiko-mybugzilla" I wonder if anyone would be against just replacing the tilde for a colon or underscore? The tilde is definitely the more common "special" character in a URL, isn't it?
Has someone yet come up with a spec for how to convert URLs into unique CSS site IDs? I know the CSS community was kicking around the idea a while ago... Gerv
Maybe Hixie knows :)

The tilde is definitely the more common "special" character in a > URL, isn't it? Underscore isn't necessarily a good choice and colon [:] would indicate a pseudo-class like :hover et al Perhaps replacing / with - and anything non-alphanumeric with nothing would be better ?
Just convert anything that isn't in the list of allowed characters to a hyphen. That's what was done with the other illegal characters (/, ., etc).
Well, in this case we'd have id="www-async-com-br--kiko-mybugzilla" is that reasonable? If so, I'll be a-patch-producin'.
How about converting double, triple, etc. hyphens in a row to a single hyphen?
Removing bug 238099 because it doesn't really block me here, but it's definitely related. I've decided to go ahead and: - swap tilde like we do with other "special" symbols - compress multiple "-"s into a single one (so we don't get www.foo.bar---bazoo for things like www.foo.bar:/~bazoo).

Comment on attachment 153774 [details] [diff] [review] kiko_v2: the right patch Looks ok. replace('[-~@:/.]+','-') is probably a tiny bit faster than replace('[~@:/.]','-').replace('[-]+', '-'), but not necessarily more legible. r=burnus for either version.

Doesn't compressing hyphens increase the risk of site ID clashes? And it doesn't massively increase readability IMO... Gerv
Yes, it increases the change for clashes, but don't you agree that the case for someone who has installations like "~kiko ~@kiko :/~--@@kiko" is rather contrived? I do appear to be the first person running into this issue..
True, rather contrived in this case. But, if we are really blazing a trail here, why not just adopt the simple algorithm Hixie suggested? We can then present our solution to the world, for their use too. It would be very handy indeed if everyone used the same mapping scheme; and hyphen compression may break other people's unique IDs in ways we can't imagine. Gerv
Did Hixie really want us to end up with IDs that had sequences of hyphens? That's what we're discussing at this point, isn't it?
Hello. Reality check. It doesn't matter. Just pick something that looks nice and go with it.
