Underscores in wikilinks should be changed to spaces for link text
Closed, InvalidPublic


Wikilinks like [[Glassfish_Application_Server]] are currently parsed into <a
title="">Glassfish_Application_Server</a>. This is ugly and awkward. People
will continue to include underscores in wikilinks since it's easiest to copy
them that way. There are multiple ways to solve this, but the easiest would
just be to globally replace underscores with space when generating anchors and
titles of links.

I disagree. First of all, you can copy easily from the page's actual title rather than the URL.
Second of all, there are some page names that should actually contain underscores, and we don't
need to introduce even *more* places where this is difficult or impossible. And finally, that
leaves the underscores in the wikitext, where it's still ugly and counterintuitive.

The title was meant to be "Underscores in wikilinks should be changed to spaces
for anchor". Sorry for the confusion.

First, what pages contain underscores, and how do you create them?

Second, if this is the case, the software can detect this distinction. As for
the underscores being ugly, that's true (and I usually avoid them), but it's not
as big a deal.

None do, but some *should*. The first one that comes to mind is the redirect [[mod_rewrite]].

Not easily, if at all.

Then your reasoning doesn't make sense to me. Underscore titles aren't
supported, and I don't see how they could be. Why should we let that stop us
from improving parsing this way?

Underscore titles are not *currently* supported in the page titles themselves. Eventually, one
hopes, we'll get around to allowing underscores along with initial lowercase letters and so on
(while treating them as more or less canonically equivalent for the purposes of user input, just
not for display).

First, initial lowercases are allowed, and even used on wiktionary. However,
they are disabled on Wikipedia.

If underscore titles were allowed, thousands of current wikilinks would have to
be changed. One way to avoid that is to rewrite (on save) underscores into
wikilinks into spaces, *until* the ability to have titles with underscores was
created. That would resolve my concerns while still allowing the possibility of
future underscore titles.

However, this begs the question of what we would use as a URL delimiter in place
of underscores. Do you have any ideas? We would either have to come up with an
escape scheme (awkward when manually typing URLs), or sacrifice a different

The link text is the text as written, period.
