Feature idea: Jump to line

[leahneukirchen]

From the interactive mode, ^Y opens the file in a pager or an editor, however you lose track of the search result.

Most Unix pagers and Editors (less, vim, emacs...) support being called like program +NNN file to jump to line NNN, this would simplify use a lot.

That's a great idea.

It is not that simple to implement though, because the TUI has no concept of line numbers of the matches. A simple implementation can take the line number shown on the screen if -n is active. This is the only clue we can use. It won't work if -n is not active, or if -l or -c are active.

[leahneukirchen]

If it only works with -n, that's good enough for me.

I've implemented this feature in my dev version. Some pagers do not support +linenum such as moar see #286 where I added a comment about this.

So we have two choices:

1. always add +linenum regardless of the pager specified, but this may not start the pager if the pager like moar returns an error.
2. only add +linenum when the pagers are more or less or vi or vim or emacs

I prefer 2 which is safe, so I'll include this in the next release.

More tools that do it: most, w3m, pico, nano, joe, zile, vile, mg, mcedit, vis, kak... :)

OK, ok... got it!

Out of curiosity @leahneukirchen, how did you come up with that list?

[leahneukirchen]

My thinking of every editor I had here and trying. ;)

Notably, helix doesn't support it (but I'll file a bug).

Implemented in ugrep v4.2 (released).
