ZSH's way to bind function to a key in a script?

ZSH's way to bind function to a key in a script?

[nix]

Hi everyone. I was reading last night about "bindkey" etc. , and i could
not get it working.

#!/bin/zsh

function foo () {

echo "Foo ooo"
}

In this script, how to bind function "foo" to a key. So lets say i press
the Space button and it should trigger foo?

zle -N foo
bindkey ' ' foo

Or

bindkey -s ' ' 'foo\n'

…if you just want to emulate an user input.

The standard examples of bindkey assume you're binding editor commands
rather than normal commands, i.e. something that helps you edit a
command line.

To bind a command to a keystroke, you need the "-s" option to bindkey.
However, note it's doing something rather different --- basically just
dumping the keys you type into the command line.  One idiom for running
"foo" this way is to use ^q to ensure there's nothing else in the buffer
(if there is, you don't lose it, you get it back after running foo), and
put a newline at the end.  Luckily you can use the same abbreviations
for keys as in the keystroke part of the command:

bindkey -s '<keystroke>' '^qfoo\n'

This assumes ^q is bound to the editor command push-line.  You can
remove the ^q if you only want to use this on an empty command line.

Then it's unrelated to bindkey ;-)

Try this:

while [ : ]; do
    read -ks a
    [[ $a = ' ' ]] && foo
done

Have a look at “man zshbuiltins” for more about the “read” builtin.

When using   "read -k key"

I am matching against normal keys with
if [ $key = '?' ]

simple control characters like tabs with
if (( #key == ##\t ))

Ctrl + key sequences with
(( #key == ##\C-u ))

But how do I match against Alt + key sequences?

Thanks,
Wendell
