FIF will have to ask grep to mark the match(s) on the line and parse them for character positions to be selected
That can be a bit tricky. -o -b returns what we need, but the normal output is be lost, while --color=always will do, but the parsing is a bit more complex, and we should invoke grep with a GREP_COLORS prefix. Both assume GNU grep, of course.
Yes, I was thinking of (ab)using the colour markings for this purpose, but we have already had problems with non-gnu grep, so maybe leave this until later.
What I meant is that focusing the window is not much use if the cursor position is going to be start of line, since I have to click in the window anyway to position the cursor (unless it happens that I want something close to the start). [...]
I get it now. FIF / Find Usage will certainly be better with line and column positioning, including Enter / double-click. Maybe implement that for the Compiler tab first? Looks easy, once I find where is the default error_regex. Huh.
Erm... looks easy? which compiler are you using that gives a column position?
GCC just gives a line number vaguely in the region that it sorta guesses is the error ;-D
