[snip] PERCENT=${${"$(acpi 2>/dev/null)"}/(#b)[[:space:]]##Battery <->: [^0-9]##, (<->)%*/${match[1]}} [snap]
Needs extended_glob set, but that's the case in that position already. Could you two test the expression above. If it works, I'll commit it later this evening.
Well, I discussed this with mika on IRC. Unfortunately, this does work for him on the command line, but not in the zshrc file. I have got no idea why that is.
The only thing that's required for that expression is extended_glob and that is set at that point.
If someone really wants that, please debug it.
Aside from the fact, that my attempt does not work: This is quite a misleading feature. PERCENT is *never* updated, AFAICS. And it requires starting zsh in a non standard way (BATTERY=1).
IMO, this feature should either be fixed or dropped altogether.
People who want this, should look into it.
