Preview file shortcut

[exploide]

Sometimes, when I type a command like mycmd --my-file ./here/comes/some/file.txt I start wondering whether I actually selected the correct file or if I mixed something up. Then I copy the file path, open a new terminal tab and open the file in less.

fish has some cool shortcuts, for example Alt+H to open the man page of the current command.

What about a shortcut for opening the current file in a pager? I think it could be useful.

I'm thinking about what shortcut would be appropriate. Some of them are already occupied for other actions. So I'm leaning towards Alt+O as in Open.

What do you think?

Good idea, seems convenient.

I'm playing around with this. It also works nicely when fish's pager is active.

bind \eo 'begin; set -l tok (commandline -ct)
	test -z "$tok" && set tok (commandline -oc)[-1]
	eval less -I $tok; commandline -f repaint; end'

We could also overload the Alt+L binding, to show the current token in a pager if it is a file.

@krobelus are you working on it? Otherwise I would give it a try.

But it should be decided whether enhancing Alt+L or introducing a new function for Alt+O is preferred. I think enhancing __fish_list_current_token with file support is great but would incidentally remove

fish-shell/share/functions/__fish_list_current_token.fish

Lines 10 to 12 in a29bc12

	set dir (dirname -- $val)
	if test $dir != . -a -d $dir
	ls $dir

which strips the filename to list the parent directory. That would obviously preview the file then. But I'm not sure if this is a no-go since I cannot imagine this is heavily used.

Sure, go for it.

I think a new binding on Alt+O is fine.
