Re: menu selection and enter key

Re: menu selection and enter key

[Virginia Mann]

When I use the line (thanks Oliver and Andrey!)

bindkey -M menuselect '^M' .accept-line

It causes my enter key to do what I want it to do (execute immediately 
instead of making me hit <enter> twice), so I put it in my .zshrc.

But when I first start up a new zsh, and .zshrc is sourced the first time, 
this line fails with the error: "no such keymap `menuselect'".

If I do some menu selection and then rerun this .zshrc, the bindkey works 
and sets the desired behavior.

It appears that I need to load something before I execute this line. Or 
maybe there's a way to instruct zsh to accept it because the needed bits 
will be loaded later (like a C++ forward declaration).

I have no idea. I don't want to accidentally switch my default keymap to 
menuselect or load more than necessary or cause something to reload 
everytime I source my .zshrc by forcing a manual load or whatever else may 
go wrong. What would be the best approach for use in my .zshrc to get this 
line to work sensibly?

Thanks.

If you are using the new completion system with the styles set for menu
selection, move this line after the call to compinit, since the
completion system will load the libraries for you.

Otherwise, put
  zmodload -i zsh/complist
just before it.  The -i stops it complaining if you re-source .zshrc.

But you may just as well continue editing current line without executing it.

Would not simple

bindkey -M menuselect '^M' .accept-line

be easier?

accept-line in menu selection is redefined to do that. If I've
understood what you want it to do correctly, you can do:

double-accept() {            
  zle accept-line && zle accept-line
}
zle -N double-accept
bindkey -M menuselect '^M' double-accept

Does that help?

menu selection and enter key

[Virginia Mann]

I'm configuring zsh for the first time and trying to understand the 
features.

I find menu completion very useful, and I like seeing the list of candidates 
below it. <tab><tab><tab> yes, that's the one I want<enter>, and it 
executes.

Then I found menu *selection*, which let me see where I was as I tabbed thru 
the candidates by highlighting where I am in the list, which is very 
convenient. Unfortunately, when I reach the one I want and hit <enter>, it 
no longer executes. Now it just inserts a space and sits there waiting for 
me to enter more. I have to hit enter again to make it execute.

I like being able to see where I am on the list more than tabbing thru it 
blindly, and I like being able to navigate particularly long lists by using 
the arrow keys (very nice), but how do I get it to execute when I hit 
<enter> the first time, just the way it does when I'm tabbing thru the list 
without highlighting? If I want to enter two parameters -- which is the 
minority of cases -- I should be able to just hit the spacebar and start 
tabbing again the way I can when the "selection" highlighting is turned off, 
I would think.

Can menu completion with selection turned on be made to execute on the first 
tab like it can with selection turned off?

Thanks.
