Since there are already plans to redesign the gui console, this feature won't be implemented for the current console for windows.

There is already the workaround that after selecting the error message with file and line number, the context menu offers an entry for opening the file at the corresponding line.

makes parse error message clickable. So, this bug seems to be resolved for Linux and Mac OS. Regarding Windows, I will have a look at using the Filter feature in the windows terminal, too.

Changed the OS to Windows.

The attached patch provides a possibility to highlight error and warning messages by escape sequences in the message strings (only for unix terminal). Since this requires changes in error.cc, I would like to know if there are any objections against this approach.

I have pushed changeset
which handles links to erroneous files like ordinary links: underlined when the mouse cursor is over it. Other highlighting of these links and the related error messages are removed due to the issues when scrolling the console output. I am currently looking for a possibility to highlight error message by coloring them via escape sequences.

provides highlighting of errors and related files in the terminal. The link to the file is clickable and opens the file at the erroneous line. By this, all error messages in the terminal buffer are highlighted and clickable, not only the one of the last error. When scrolling the terminal window with highlighted errors, some artifacts will appear, which can hopefully be fixed soon.

Patches for highlighting syntax errors and warnings will follow.

For now, this method does not work in windows.

This very useful feature is still very hidden in Octave 4.2.0.

I've used the Octave GUI for years without knowing about it. So I'd like to also vote for the suggestion in comment #5.

Torsten, that feature is nice, but a little hidden.  I needed to read the code to discover that I had to select the text for it to appear in the context menu.

How about just calling (F)lasterror and add that to the context menu even if no error message is selected?

provides the possibility to edit a file from a selected error message via the context menu.

This might depend on bug #41076, adding support for clickable hyperlinks in the command window.

Ok. I see the category has already been marked as "GUI"

Fritz are you running the developer's experimental gui ?

When a script stops on an error, octave's error message is displayed in the 'Terminal' tab.

It would be very helpful if clicking on that error message could bring you directly to the corresponding line of the tab showing that m-file (open file in new tab if it's not opened already).

This is the way it's done in Matlab, and I'm sure it would increase the productivity using octave-gui enormously.
