Hi Per, Are real subcripts/superscripts planned?
There has been no specific plan to date, for this or any of the many other things lacking in Texinfo. Your message is very helpful in that regard. (2) Introduce new @sub and @sup commands (or @subscript/@superscript @sub and @sup sound good to me. The only complication I can think of is that \sup already exists in TeX (typesets the mathematical operator "sup", three roman letters). It would not be feasible to distinguish @sup from \sup, although of course it would be trivial to create \supop or some such to still be able to access it. I rather suspect that the number of existing Texinfo documents that use TeX's \sup is zero. In info or plaintext: ^TEXT In HTML: <sup>TEXT</sup> In DocBook: <superscript>TEXT</superscript> In XML: I suggest <sup>TEXT</sup> In TeX inside @math: ^{TEXT} In TeX otherwise: use a macro ... That all sounds fine to me. I only wonder about Info/plaintext needing some kind of delimiter in the case where TEXT is multiple characters. As in x@sup{2y} is different from x@sup{2}y, but both would be represented by x^2y given the above. Maybe x@sup{2y} should go to x^(2y) in Info. That's a math example so I suppose people should use @math, although you can be sure that once the feature exists, it will get (ab)used for everything possible. I'm not sure if there are examples of textual super/subscripts where parens or something would be desirable. I can't think of any; something like 1@sup{st} is readable enough as 1^st (ugly enough, too). Patrice, Gavin, wdyt? Thanks, Karl
