most-recent-file completion and accept-line

most-recent-file completion and accept-line

[Eric Smith]

One of the most useful lines in my config file is:
bindkey '^O' most-recent-file

How do I bind a key combination to complete the most recent file
and then automatically run accept-line or <enter> on this
filename?

(my preexec function will do the necessary on the file).

thanks a lot :)

This seems like an odd question, because any key _combination_ you choose
will be at least as many keystrokes as typing ctrl-o enter.  Normally you
want bindings for things that would otherwise take lots of keystrokes.

However:

accept-most-recent() {
  zle most-recent-file && zle .accept-line
}
zle -N accept-most-recent
bindkey '^X^O' accept-most-recent

Thanks a lot Bart.

When I tried this previously, I could not get it to work, now it kinda works,
so I finally respond.  Except you need to press the key combo twice, once for
all the possible options to appear and after the second press it accepts one of
the listed files.

Perhpas I have something configured that interferes with it?
Any way FWIW, here is my experience:

So I bind your function to ^O

Notice the "&&" in there -- if the most-recent-file widget does not yield 
a zero status, accept-line will not be executed.  However, I don't know 
what if any circumstances would cause a nonzero status.

I hadn't noticed before, but in my zsh installation the name of the widget 
is _most_recent_file, [*] not most-recent-file, so there must be something 
else you're doing to create the hyphenated-name version.  Maybe that would 
provide a clue.


[*] And it's bound to ^Xm as well.
