Is there a way to increase the output line length of \errmessage and \typeout? My problem is that some error messages in my console and log file are cut within the error content:

--> Error: This is my very long<LF>
error message.

Instead I would like to have:

--> Error: This is my very long error message.

in one line because I've to parse the log file.

Many thanks in advance.

You can not control this within TeX but web2c based implementations have


% It's probably inadvisable to change these. At any rate, we must have:
% 45 < error_line      < 255;
% 30 < half_error_line < error_line - 15;
% 60 <= max_print_line;
% These apply to TeX, Metafont, and MetaPost.
error_line = 79
half_error_line = 50
max_print_line = 79

These settings are usually set in a texmf.cnf file but you can also set them on the commandline so

\documentclass{article}

\begin{document}


\typeout{+123456789+123456789+123456789+123456789+123456789+123456789+123456789+123456789+123456789+123456789}
\end{document}
