"Alt ." to repeat last part of a command

"Alt ." to repeat last part of a command

[Carlo Trimarchi]

Hi,
how can I use the "Alt ." combination to repeat the last part of a
command? When I used bash I used a lot this.
Or, maybe, is there any other combination in zsh to do the same thing?

Thanks,
Carlo

Not sure I understood what you mean, but maybe :

bindkey -s '^[.' '!#$'

I suppose you meant "Esc ." (Alt combinations don't make sense in
a terminal, they are translated to something else, e.g. by Esc).

It should work in zsh:

ypig% bindkey '^[.'
"^[." insert-last-word

Or

bindkey -s '^[.' '!$'

if you want the last part of the /previous/ command

function last-arg()
{
    LBUFFER+=' !$'
    zle complete-word
}
zle -N last-arg
bindkey '^[.' last-arg

not to have to press <space> and <tab>

It depends a bit on the terminal... some turn "Alt ." into "Esc .", other pass
through "." with the 8th bit set.  If the latter is happening you'd need to
use "bindkey -m" to apply the appropriate definitions, which means you
can't use non-ASCII characters from the keyboard (this consequently
produces a warning nowadays).  A better option might be to investigate
whether your terminal can convert the "Alt . input" into "Esc ."

Unless you're in vi mode, in which case you can just bind it in the obvious
way.

bindkey -M viins '\e.' insert-last-word

This would mean there's a delay when you hit Esc to go to command mode,
because the shell needs to decide whether there's a "." next or not.

No, I meant "Alt ."

In bash, at the moment, I can do this:

$ ls workspace/

then I can press "cd Alt ." to show the command "cd workspace/"

In zsh it seems that "Alt ." executes "cd .." and it brings me to the
parent directory.

Thanks, I'll try

This is what you type. But for the shell, there's no such thing.
You need to know what your terminal does with "Alt .".

When you run 'zsh -f', does 'Alt .' work? If not, what about after
running 'bindkey -e'? Do you have EDITOR set?

No, it doesn't.

Yes, it works like I want. I mean, it repeats the last part of a command.

> Do you have EDITOR set?

I think it is set to vim:

lloyd% echo $EDITOR
vim

so this bit of my previous message is what you need...

bindkey -M viins '\e.' insert-last-word

I see, thanks. I think I have to read something about this in the documentation.

Unless you particularly want to use vi mode, you probably just want to
put "bindkey -e" early in your .zshrc (early meaning before other
bindkey commands).
