This would be neat for linking to source locations in the terminal and in the console output of an IDE.

That is one of the defaults that ships with plan9. Any text of the form

    [A-z0-9/_.,-]+:[0-9]+ 

I..e a path with a line number - e.g. /sys/src/lib9/9.h:5

Will open that file in your editor at that line.

The plan9 utiiities, such as grep -n, will present filenames with line numbers in that form.

It is trivial to add your own such that

    Error X in file /path/to/file on line 5

Will do the same.

Before plan9 had a usable html4 renderer I would send URLs to a listener on a Unix machine with firefox to open them there inside my VNC session.
