How to disable zsh substitution/autocomplete with URL and backslashes

I am using zsh with oh-my-zsh on Ubuntu:14.04.

The shell autocompletes escape character with backslash when I paste a URL.

For example with environment variables:

$ wget http://{DEFAULT_IP}/index.html
It will become:
$ wget http://\{DEFAULT_IP\}/index.html

How can I disable this function?

Solution

new version(> 486fa10) oh-my-zsh have a configuration for this, add DISABLE_MAGIC_FUNCTIONS=true before source $ZSH/oh-my-zsh.sh:

DISABLE_MAGIC_FUNCTIONS=true
source $ZSH/oh-my-zsh.sh

Original answer:

This is a bug in zsh 5.1.1 ~ 5.2(current).

The plugin bracketed-paste-magic did not works in the zsh versions.

The issue is here:

I suggest you disable bracketed-paste-magic.

Comment these code from oh-my-zsh's ~/.oh-my-zsh/lib/misc.zsh solve the problem:

if [[ $ZSH_VERSION != 5.1.1 ]]; then
  for d in $fpath; do
    if [[ -e "$d/url-quote-magic" ]]; then
      if is-at-least 5.1; then
        autoload -Uz bracketed-paste-magic
        zle -N bracketed-paste bracketed-paste-magic
      fi
      autoload -Uz url-quote-magic
      zle -N self-insert url-quote-magic
      break
    fi
  done
fi
