Ag adds "File: " before each match which breaks compile-goto-error

[sagittarian]

Each match starts with "File: ", and compile-goto-error interprets that as part of the file name, so it can't find the file. I found where it does that in ag-filter, removed it and recompiled ag.el, and now it the result buffer works for me.

On my machine, the output of ag --version is: ag version 0.31.0

My Emacs version is: GNU Emacs 24.5.1

I'm using: Ubuntu 16.04

The ag-group-matches custom is what causes this behavior. Toggling if off restored next-error / previous-error functionality for me.

I have same issue, I think it is not related to ag-group-matches. It should improve it.

[joedicastro]

I had the same issue, and setting ag-group-matches to nil as @michaelbartnett suggested worked fine for me.

[LefterisJP]

I actually ended up removing the "File: " from the corresponding line in my local copy

ag.el/ag.el

Lines 647 to 650 in d00aa65

	(while (re-search-forward "\033\\[1;32m\\(.*\\)\033\\[0m\033\\[K" end 1)
	(replace-match
	(concat "File: " (propertize (match-string 1) 'face nil 'font-lock-face
	'compilation-info))

But then I realized it's conditional to ag-group-matches so yes indeed setting it to nil works.

But this leads me to question this behaviour of the tool. Why is grouping same-file results under one file name more important to jumping to the result's location? @Wilfred ?

It would be nice if the compilation buffer could succesfully jump to the file even if "File: " is prepended to the start of the line. There probably is a way to achieve this but my emacs-lisp foo is not good enough.
