No diagnostics shown if you \input{preamble} or use pre-compiled headers.

[gi1242]

If you \input the preamble, or use a pre-compiled headers, then all diagnostics go away.

Here's a minimal working example:

\documentclass{minimal}
\begin{document}
This is an \undefined command
\end{document}

Now all diagnostics work. However if I create a file preamble.tex with

\documentclass{minimal}

and then create a tex file with:

\input{preamble}
\begin{document}
This is an \undefined command
\end{document}

Then no diagnostics are shown at all.

The same happens if I use a file with a pre-compiled header:

%& preamble
\begin{document}
This is an \undefined command
\end{document}

Now you have to compile the preamble with:

pdflatex -ini -jobname=preamble "&pdflatex preamble.tex \\dump"

and then compile the document as usual. All diagnostics are missing. As soon as I add a \documentclass line to the main document, the diagnostics come back. Is there any way around it?

Thanks in advance.

@gi1242
Thanks for the report! This should be fixed by bd38d6f.

THANK YOU SO MUCH!!!

As a workaround (until the next release) I realize I can trick texlab by using

\iftrue\else\documentclass{minimal}\fi

(It doesn't work with \iffalse.)
