ID 112 Closed (Not a Bug) glossaries 4.24 Glossary Label With Backslah Characters?

Report

It seems glossary label can contains math but backslash, e.g.: \newacronym{$\beta$}{$\beta$}{$\beta$} Is it possible to support labels with backslash characters in the future? Actually, I am designing a LyX module for glossaries package. If labels with backslashes are possible, it can design a LyX \gls inset to preview maths containing backslashes directly in LyX and the maths are also glossary labels which are used as ordinary glossary labels. Thus, I need the support of glossary labels with backslashes.

Evaluation

No, I'm sorry, it's not possible for the same reason that you can't do \label{$\alpha$}. As mentioned in the user guide, the label can't contain any active or special characters (which includes backslash). The reason for this is that the label is used behind the scenes to define associated internal commands that store the relevant information. The label also needs to be fully expandable to allow it to work in iterative contexts (for example, commands like \glsunsetall require this).

(Unrelated, but note also that the manual recommends defining entries in the preamble not in the document environment.)

Since this is a documented feature I'm going to have to close this as not a bug.
