engine: hyperref pdftitle/pdfauthor set the PDF document metadata - #211
Merged
Conversation
The engine built every PDF with an empty information dictionary, so a produced
document had no title or author in its properties — a viewer showed the filename
and reference managers read nothing. \hypersetup{pdftitle=…,pdfauthor=…} (and the
package-option form) now populate go-pdfkit's /Info /Title and /Author.
Because go-pdfkit v0.10.0 encodes a non-ASCII text string as UTF-16BE, an accented
title — pdftitle={Résumé des travaux} — is correct in the PDF, which is the direct
payoff of that encoding work.
Scope: pdftitle and pdfauthor map to go-pdfkit's existing Title/Author. pdfsubject
and pdfkeywords need new go-pdfkit Info fields and are left for a follow-up.
Verified: a document with pdftitle/pdfauthor renders /Title and /Author in the
(uncompressed) info dictionary from both the \hypersetup and package-option forms;
an accented title is UTF-16BE (<FEFF…>), not raw UTF-8; a document with no pdftitle
emits no /Title as before. Full suite, conformance ratchet, go vet and gofmt green.
