Misplaced error marker

[vigoux]

Hi, using the following file, the Undefined control sequence error is declared at the start of the line, while it happens a lot later.

Is it something to be expected ?

\documentclass{article}

\begin{document}

Foo \bleh{bar}. % Error reported at the start of this line
%    ^^^^ should be reported here.

\end{document}

From what I see of the code, changing the TEX_ERROR_REGEX to the following:

(?m)^! ((?P<msg1>(.|\r|\n)*?)\r?\nl\.(?P<line>\d+)|(?P<msg2>[^\r\n]*)) (\.\.\.)?(?P<hint>.+)?

This would allow to at least capture a hint group that show the placement of the context of the error.

For the record, on the following error, the hint group captures Foo \bleh:

! Undefined control sequence.
l.5 Foo \bleh

I'll try to see if I can hack something in.

Thanks for the report.

Kind of at the moment. The current log parser is quite simple in this regard and only uses the l.5 line to determine the error range.

Thanks! This would be a nice addition.
