Hi!
How to expand \translate so that it doesn't show up in the PDF
metadata? Example:
\setupdocument [metadata:title=\documentvariable{title}]
\mainlanguage  [sv]
\startdocument [title={\translate[en=Foo, sv=Bar]}]
   \input knuth
\stopdocument
This literally shows:
Title: \translate [en=Foo, sv=Bar]
The following workaround does the job, but it's not that elegant:
\setupdocument [metadata:title=\documentvariable{title}]
\enablemode [sv]
\startmodeset
   [en] {\mainlanguage[en]\startdocument[title=Foo]}
   [sv] {\mainlanguage[sv]\startdocument[title=Bar]}
\stopmodeset
\input knuth
\stopdocument
Is there a better mechanism to support multiple languages in the
PDF metadata or just have \translate expanded?
\mainlanguage[sv]
\startmodeset
     [*en] {
         \setupdocument [metadata:title=Foo]
     }
     [*sv] {
         \setupdocument [metadata:title=Bar]
     }
     [default] {
         \setupdocument [metadata:title=Far]
     }
\stopmodeset
\startdocument [title={\translate[en=Foo, sv=Bar]}]
   \input knuth
\stopdocument
That works and seems cleaner, thanks.
