zsh Issue - "Tab" character is not pasted into shell

zsh Issue - "Tab" character is not pasted into shell

Hi all,

I recently experimented an issue when pasting "tab" characters to zsh
terminal. Whereas
changing the shell to "sh" or opening a terminal editor like "nano" allowed
me to paste
a text with tabs, when copying the same text with tabs into "zsh" it
literally EATS the TAB
characters.

I've observed this behaviour in Ubuntu 12.04/14.04 (within Biolinux
distribution).

I hope there is a workaround or some trick I may not know.

Many thanks for your help in advance,
Xavi

Ex:
Text in "Leafpad" (plain text editor):

this<TAB>is<TAB>a<TAB>test

When coyp/pasted (via menu or shortcut(Ctrk+Shift+V) to sh or nano the
output is as expected:

this<TAB>is<TAB>a<TAB>test

But when pasted to "zsh" the output is:

thisisatest

Without special copy&paste support, "pasting" just means the terminal
emulator types in the text very quickly, and <TAB> means to do
completion in this case...

That said, recent zsh support terminal copy&paste, so with my zsh 5.2
this works out of the box (setopt zle_bracketed_paste), at least in
urxvt and xterm.

Hope this helps,

If you are using completions from "compinit" you can do this:

    zstyle ':completion::*' insert-tab 'pending=1'

This causes completion to look for pending input when it sees a TAB
character and insert the tab literally if there's more input after it.
Typically this happens only when pasting unless you are working with
a very slow connection or a heavily loaded CPU, so the effect is that
you are able to paste tabs without having completion consume them.

} That said, recent zsh support terminal copy&paste, so with my zsh 5.2

There's actually no setopt for this, it's on by default.  To turn it
OFF you must do "unset zle_bracketed_paste" (it's a parameter, not an
option).

Since I use "zsh 4.3.17 (x86_64-unknown-linux-gnu)" version the trick
"zstyle ':completion::*' insert-tab 'pending=1'" worked for
me. I will put it in ".zshrc".

I usually deal with tab-delimited tables, and it was really annoying for me
when I wanted to parse some parts using shell commands

Thank you very much!
