luatex and javascript

luatex and javascript

[Zhichu Chen]

Hi,

I've searched the list and it seems that no one has been occurred
to my problem.

Has the javascript interface gone? 'cause I failed the following
simplest file:
================================================================
\setupinteraction[state=start]

\starttext

A few years back, \TEX\ could only produce \fillinfield [dvi]
{DVI} output, but nowadays, thanks to \fillinfield {Han The
Thanh}, we can also directly produce \fillinfield [pdf] {PDF}!
Nice eh? Actually, while the first field module was prototyped
in ACROBAT, the current implementation was debugged in
\fillinfield [pdfTeX] {\PDFTEX}. Field support in \fillinfield
[ConTeXt] {\CONTEXT} is rather advanced and complete and all
kind of fields are supported. One can hook in appearances, and
validation \fillinfield [JavaScripts] {JAVASCRIPT}'s. Fields
can be cloned and copied, where the latter saves some space. By
using \fillinfield {objects} when suited, this module saves
space anyway.

\stoptext
================================================================

It's copied from the mwidget-s.pdf

My luatex is 0.30.3, and I just run "luatools --generate" and
"ctxtools --update" today.

The error message is:
================================================================

No, just bugged. Hans ran into that himself yesterday, actually.
I cannot look up the actual fix from here, but it comes down to
a pretty simple catcode mixup. Hans will probably post it sometime
tomorrow.

Best wishes,
Taco
