[NTG-context] externalfigure crashed

[-- Attachment #1.1: Type: text/plain, Size: 565 bytes --]

When \externalfigure could not find the file it used to graciously place a rectangle kindly telling the user that the file has not been found.
But now, however, it seems the default in this case is a crash. Very annoying in comparison with the earlier behaviour.
I might make a mistake, but the MWE is as simple as can be.

The filename is test.jpeg, then this runs ok:
\starttext
\externalfigure[test.jpeg][]
\stoptext

But this crashes, see the log:
\starttext
\externalfigure[test.jpg][]
\stoptext

You injected something that confused the parser, maybe by using some Lua call.

Can you update your ConTeXt installation and check if the error remains,
I tries to your example on my machine (Windows 11) and wasn't able
to reproduce the problem.

1. What is the version of your Luametatex binary?

     luametatex --version
     This is LuaMetaTeX, Version 2.10.11


2. What do you get in your log-file with the following example!

     \starttext
     \show\expandeddetokenize
     \stoptext

On my system I can find the following line:

I get the same error on linux. I am using 2023.09.26 which appears to be the latest version available for linux.

The issue is that \expandeddetokenize used in the definition of grph_include_replacement is not defined.

A simple \def\expandeddetokenize{\relax} fixes the error, but clearly that is not a proper solution.

For me, it is the same:

This is LuaMetaTeX, Version 2.10.11

\expandeddetokenize=undefined

Not sure why this is the case!

Hi Hans,
I have the same problem and definitely need to use \externalfigure[] this
weekend. In which file should this patch be added ?
Thanks.

Sorry, Hans, if I am missing the point.

Does the above mean that ConTeXt will be able to sign PDF documents with
digital certificates?

Many thanks for your help,

Well, that's what singing is, right? The problem is actually less in the 
signing than in the certificates themselves.

Basically one can sign (with some certificate) and then validate.


% sign-001.tex

\setupinteraction[state=start]

\definefield[signature][signed]

\defineoverlay[signature][my signature]

\starttext
     \startTEXpage[offset=1ts,frame=on,framecolor=darkblue]
         sign: \inframed
           [background=signature,framecolor=darkred]
           {\fieldbody[signature][width=3cm,option=hidden]}
     \stopTEXpage
\stoptext

after neing processed:

mtxrun --script pdf --sign --certificate=sign-001.pem --password=test 
sign-001 (--library)

and:

mtxrun --script pdf --validate --certificate=sign-001.pem 
--password=test sign-001 (--library)

etc. works here.

Hans

Many thanks for your explanation, Hans.

These are great news. I wonder whehter it would be feasible to extend
this to use smart cards (through Firefox).

Many thanks the new implementations,
