Description Christopher Yeleighton 2007-07-02 11:46:00 UTC
Using the italic text tag for symbols is semantically incorrect: it does not distinguish symbols from other uses of italic text.  It would be better to replace it with the variable tag.
That is, <math >X</math > thould transform to <span class="texform" ><var >X</var ></span > instead of merrie olde <i >X</i >.
Comment 1 Christopher Yeleighton 2008-06-13 19:27:38 UTC
Except for constants: log <i >e</i > = 1, sin <i >&pi;</i > = 0, etc.

No need to differ here: Constants like e, pi, i ... should never be italic in TeX. The user has to tell when it is a variable and when it is a constant.
Comment 3 Aryeh Gregor (not reading bugmail, please e-mail directly) 2011-01-05 19:07:47 UTC
Constants such as e and i are traditionally italicized in mathematical typesetting, same as variables.  But I think <var> is appropriate for them anyway, even though they're not actually variables -- they're supposed to be presented the same as variables.
Comment 4 S. McCandlish 2012-03-04 12:29:33 UTC
I belatedly concur with Aryeh.  HTML's <var>...</var> isn't a declaration that something IS a variable, it's an instruction to the user agent to format it as one.

As HTML support was disabled by 09679f2f39e6c6c00e87757292421b26bfa7022a, closing as WONTFIX.

Tim Landscheidt, what does this mean?:

The link that generated (to,09679f2f39e6c6c00e87757292421b26bfa7022a,n,z) doesn't provide any information.  This bug is a bug, not a feature, and still needs to be fixed.

The var element has certainly not been "disabled" (deprecated) in HTML5, if that's what this meant:
Comment 7 Tim Landscheidt 2014-06-22 22:37:18 UTC
I was referring to; with that commit, the support for HTML in Extension:Math was disabled, so no HTML is generated anymore.  MediaWiki 1.19 was released after that commit, so there's nothing left to fix.
