Dear list,
I have the following sample:
\setupinteraction[state=start]
\starttext
\startluacode
function document.special_attachment(reference)
year = reference:sub(7, 10)
attachment_url = "https://www.boe.es/buscar/pdf/"; ..
year .. "/" .. reference .. "-consolidado.pdf"
return attachment_url
end
\stopluacode
\unexpanded\def\giveattachment#1{%
\cldcontext{document.special_attachment("#1")}}
\def\cE{BOE-A-1978-31229}
\attachment[file={\giveattachment{\cE}}, color=red]
\attachment[file={https://www.boe.es/buscar/pdf/1978/BOE-A-1978-31229-consolidado.pdf},
color=blue]
\giveattachment{\cE}
\stoptext
I don’t know why I do get the second attachment, but not the first one.
Lua code seems to be fine (given the last command in the sample).
Could anyone explain me what I’m doing wrong?
You try to pass a protected (\expanded\def) command to a argument of
another command
which doesn't work: Remove \unexpanded and your output is as expected.
\def\giveattachment#1%
{\cldcontext{document.special_attachment("#1")}}
or
\def\giveattachment
{\cldcontext{document.special_attachment(tokens.scanners.string())}}
als also make
year
attachment_url
local variables
