Can you show the text (and commands) which appears on line 540 (plus a few lines before/after line 540) of your document.

I attach the dev.log and dev-error.log. Is it enough?

You should show a *complete* context source document that generates the error. See https://tex.meta.stackexchange.com/questions/228/ive-just-been-asked-to-writ... (Most of the advice here is latex specific, but the idea is the same for context). Aditya

After I run context (LMTX version) to my document (attached) I get this error:

tex error > tex error on line 540 in file ./dev.tex: The file ended when scanning an argument.

I don't know how to start... Can anyone help me?

Thanks, Xavier

PS: I receive this error after upgrading to MKIV to LMTX. Before with MKIV I get no errors.

I suspect that LMTX is a bit more strict about parsing. You have omitted the required \par for each \head.

Perhaps the mtxrun check script (https://wiki.contextgarden.net/Mtxrun) could be enhanced to pick this up. -- Rik

Thanks, Wolfgang, for pointing this replacements. I will try to change that but it's a lot of work. Appreciate Xavier On Mon, 14 Aug 2023 19:07:09 +0200 Wolfgang Schuster ha escrit:

You're correct, \head is the cause of the error and it's better to replace it with

    \starthead {...}         ...     \stophead

but there are more things which can be changed to use modern syntax (in many cases part of ConTeXt since nearly a decade).

A few examples:

    - \startexercici[<REFRENCE>]{<TITLE>}  --> \startexercici[reference=...,title=...]

    - \placetable[<PLACEMENT>][<REFERENCE>]{<TITLE>}{...} -->  \startplacetable[reference=...,location=...,title=...] ... \stopplacetable

    - Llimones........ \hfill 6  -->  Llimones \filler[symbol] 6

    - \bigskip  -->  \blank[big]

    - \startexercici[<REFRENCE>]{<TITLE>}  --> \startexercici[reference=...,title=...]

with LMTX this

\startitemize \sym{\in[REFERENCE]} \stopitemize

does not work.

You have to provide a example for the error because it works for me. \starttext \startsection [reference=foo,title=Foo] \startitemize \sym{\in[foo]} xxx \stopitemize \stopsection \stoptext Wolfgang

Thanks, Rik, for the comment. You're right. Note that I've never been aware of such requirement because always in MKIV I use \head without \par.

@all, please comment it out this behaviour in somewhere. The weak point of context is documentation: wiki is too bit not updated and reference manual are outdated. As a simple user, it could cause nightmares, overall in transition to one major version to another.
