newlines in return Lua string

newlines in return Lua string

[Hans van der Meer]

[-- Attachment #1.1: Type: text/plain, Size: 430 bytes --]

From 	\ctxlua{tex.print(hvdm.myluacall("\xmlatt{#1}{argument}"))}
Lua returns a string containing newline characters '\n'.

In ConTeXt this returned string is printed as one line, the embedded newlines are not honoured.
I thought to replace with \crlf in this manner: string1 .. "\\crlf" .. string2 but the returned \crlf are not executed as such.

How to force \crlf's in the executed return?

Hard to say without a minimal example, but how about:

\startluacode
context.startlines()
context(hvdm.myluacall("\xmlatt{#1}{argument}"))
context.stoplines()
\stopluacode

or

\startlines
\ctxlua{context(hvdm.myluacall("\xmlatt{#1}{argument}))}
\stoplines
