Bracketed paste mode support?

[Masakazu Ohtsuka]

What is the peco version, OS, architecture?

peco version v0.5.0
macOS 10.12.3
zsh 5.2 (x86_64-apple-darwin16.0)
tmux 2.3

Abstract

When pasting into peco (in this case "test"), I see:

The extra [200~ and [201~ limits the input, which is what I don't want.
When pasting the same into zsh directly, zsh will highlight the pasted "test".

Discussion

Looks like it's related to Bracketed paste mode: https://cirw.in/blog/bracketed-paste
Is this an issue in peco or a FAQ related to zsh/tmux?

[lestrrat]

beats me... I use zsh, but not tmux, and have never encountered this issue... so I'm guessing tmux?

[Masakazu Ohtsuka]

hmm weird.

Turns out, the issue happens without tmux,
when using following zsh function and type Ctrl+r

function peco-history-selection() {
    BUFFER=`history -n 1 | tail -r  | awk '!a[$0]++' | peco`
    CURSOR=$#BUFFER
    zle reset-prompt
}
zle -N peco-history-selection
bindkey '^R' peco-history-selection

but when directly running

% history -n 1 | tail -r  | awk '!a[$0]++' | peco

and pasting some string works as expected.
So it should be my zsh config causing this?

[lestrrat]

Ha! I was able to reproduce it using your function
But I still have absolutely no clue why this happens. I need somebody with more terminal-fu to prod me to look at the right direction.

It seems not to be a peco issue.
In zsh 5.1 or later, it seems that "bracketed paste mode" works by default. This causes only within zle widget.

Calling unset zle_bracketed_paste seems to avoid this problem.

[lestrrat]

Yeah, that seems to work for me. @mash if it works out, it would be great if you could create a FAQ entry for this

[Masakazu Ohtsuka]

Here you go.

After some research, unsetting zle_bracketed_paste globally didn't feel right for me, because it has it's own purposes, ex: safe when pasting multiple lines in zsh.
So I came up with following snippet, which early exits from bracketed paste mode.

function peco-history-selection() {
    if (($+zle_bracketed_paste)); then
        print $zle_bracketed_paste[2]
    fi
    BUFFER=`history -n 1 | tail -r  | awk '!a[$0]++' | peco`
    CURSOR=$#BUFFER
    zle reset-prompt
}
zle -N peco-history-selection
bindkey '^R' peco-history-selection

[lestrrat]

closing.
