如何使用ZSH ZLE将文本插入到输入提示中

Question

I'd like to have a keybinding, that would paste text at the cursor within a prompt.

For example:

Prompt: ls _

Press CTRL-Z

Prompt: ls textGoesHere

I'm creating a ZSH ZLE widget, but I can't figure out how to achieve the above.

You can access the command buffer from within widgets with the parameters BUFFER , LBUFFER and RBUFFER . BUFFER contains the whole command, while LBUFFER only contains the part left of the current cursor position and RBUFFER the part to the right of the cursor. These parameters can also be modified.

If you want to insert some text at the cursor position, you can just prepend the desired text to RBUFFER :

addText () {
    text_to_add="textGoesHere"
    RBUFFER=${text_to_add}${RBUFFER}
}
zle -N addText
bindkey '^Z' addText
