Yeah this is a very cool program but it is hard to explain. Let me try anyway.
I often have to run a diff -qr between two directories, and end up with
output like this:
$ diff -qr a b
Only in b: changelog
Only in a: CHANGELOG
Files a/install and b/install differ
Files a/src/commands/access and b/src/commands/access differ
...many more lines like those above...
Typically, I'd want to examine one or two of those differences in more detail,
by running a vimdiff on them.
But can you see how hellish it is to copy paste the two filenames into a
vimdiff command?
And I assure you it gets worse if any of those filenames have spaces in them. (Way back when I was younger and angrier, I used to say that people who use spaces in filenames should be shot, but that ship has sailed. Sigh...!)
Well, my solution is yet another example of using argmod, and it is a
program called Files. Yes, literally that, because I simply triple-click to
select the whole line I am interested in, and paste it into the terminal.
In other words, the command is literally
Files a/src/commands/access and b/src/commands/access differ
and up pops vimdiff with the two filenames loaded. Works even with spaces in
filenames. (Well, as long as one of thoe filenames does not have the string and in the name I guess!)
