fix: TeX Live 2026 compatibility for beamer mode#69
Merged
Conversation
Root cause: hyperref={breaklinks=true} in \def\documentclassOptions
caused babel to crash when processing options via macro expansion
in babel v26.5. The curly braces inside the \def were misinterpreted.
Changes:
- Remove hyperref={breaklinks=true} from beamer documentclass options
(was redundant, already set in fhv.sty)
- Skip scrhack for beamer (tocbasic unavailable, causes \addtotoclist error)
- Use \hypersetup{breaklinks=true} for beamer instead of \usepackage[]{hyperref}
to avoid option clash (beamer loads hyperref internally)
- Load fontenc and inputenc before babel
