labeltext via lua

labeltext via lua

[Andreas Schneider]

Hello,

if I define a labeltext via \setuplabeltext[en][test=Something], how can 
I access that value via lua?
(context.labeltext obviously prints the content, but doesn't allow me to 
use it in lua).

As a related side-request: how can I fix expansion in cases like this: 
\startsectionlevel[title=\labeltext{test}] ... this causes the bookmark 
to read "test" instead of "Something". \expandafter\startsectionlevel... 
didn't cut it.

Best regards
Andreas

languages.data.labels.texts.appendix.labels.en

look into lang-txt.lua

Hello Hans,

I already looked into this and even printed the whole languages.data 
table at runtime, but didn't find my keys in there.

Here is an example which apparently doesn't work (or I'm still 
overlooking something):

```
\mainlanguage[de]

\setuplabeltext[de][Page=Seite]
\setuplabeltext[en][Page=Page]

\starttext

\startluacode
	local language = languages.numbers[tex.getcount("mainlanguagenumber")]
	local lbl = languages.data.labels.texts["Page"]
	local text
	if lbl == nil then
		text = "[NOT FOUND]"
	else
		text = lbl.labels[language]
	end
	context("For language "..language.." we get "..text)
\stopluacode

\stoptext
```

Thank you very much!

Best regards
Andreas

because additional ones live at the tex end

why not use context.labeltext etc?

`context.labeltext` would immediately print the label, so I cannot use 
the value within lua. My workaround would be a crossover between lua and 
tex, but that results in the bookmark having the wrong label:

\setuplabeltext[en][test=Something]
\startluacode
context.startsectionlevel{title="\\labeltext[test]"}
-- ...
context.stopsectionlevel()
\stopluacode

The title correctly reads "Something", but the bookmark in the PDF 
viewer shows "test".


Best regards,
Andreas

\enabledirectives[references.bookmarks.preroll]

Nope, that works :-)

I certainly can live with that solution. Is there reason to not have 
this enabled by default? (I know, there is a slight performance penalty, 
but it seems strange that the bookmark defaults to the title, while the 
title gets expanded but the bookmark doesn't. In any case, I will try to 
figure out where in the wiki this information best belongs to.)

Thank you very much!

Andreas
