A simple plugin that auto-closes, deletes and skips over matching delimiters in zsh intelligently. Hopefully.

NOTE: zsh-autopair is untested for versions of Zsh below 5.0.2. Please report any issues you have in earlier versions!

e.g.

• echo | => " => echo "|"
• rm -f *.| => { => rm -f *.{|}
• git commit -m "|" => backspace => git commit -m |
• cat ./*.{py,rb|} => } => cat ./*.{py,rb}|

Download and source autopair.zsh

antigen-bundle hlissner/zsh-autopair

if ! zgen saved; then
    echo "Creating a zgen save"

    # ... other plugins

    zgen load hlissner/zsh-autopair

    zgen save
fi

Prezto's Editor module will reset autopair's bindings. A workaround is available in issue #6.

Load autopair after compinit, otherwise, the plugin won't work.

zplug "hlissner/zsh-autopair", nice:10

zsh-autopair sets itself up, unless you have AUTOPAIR_INHIBIT_INIT set.

• If delimiters on the right side of the cursor are interfering with completion, bind Tab to expand-or-complete-prefix. Which will offer completion and ignore what's to the right of cursor.`

  bindkey '^I' expand-or-complete-prefix

• zsh-autopair will interfere with isearch, and will disable itself in isearch, so long as AUTOPAIR_INHIBIT_INIT is not set.

• Works wonderfully with [zsh-syntax-highlight] and ZSH_HIGHLIGHT_HIGHLIGHTERS+=brackets. Just be sure you load zsh-syntax-highlight after zsh-autopair.

• Mixes well with these vi-mode zsh modules: surround, select-quoted, and select-bracketed (they're built into zsh as of zsh-5.0.8)

• Check out my zshrc. I've spent unholy amounts of time tweaking it.

Feel free to tweak the following variables to adjust autopair's behavior:

• AUTOPAIR_BETWEEN_WHITESPACE (default: blank): if set, regardless of whether delimiters are unbalanced or do not meet a boundary check, pairs will be auto-closed if surrounded by whitespace, BOL or EOL.

• AUTOPAIR_INHIBIT_INIT (default: blank): if set, autopair will not automatically set up keybinds. Check out the initialization code if you want to know what it does.

• AUTOPAIR_PAIRS (default: (` ` ' ' " " { } [ ] ( ) < >)): An associative array that map pairs. Only one-character pairs are supported.

• AUTOPAIR_LBOUNDS/AUTOPAIR_RBOUNDS (default: see below): Associative lists of regex character groups dictating the 'boundaries' for autopairing depending on the delimiter. These are their default values:

  AUTOPAIR_LBOUNDS[all]='[.:/\!]'
  AUTOPAIR_LBOUNDS[quotes]='[]})a-zA-Z0-9]'
  AUTOPAIR_LBOUNDS[braces]=''
  AUTOPAIR_LBOUNDS['"']='"'
  AUTOPAIR_LBOUNDS["'"]="'"
  AUTOPAIR_LBOUNDS['`']='`'
  
  AUTOPAIR_RBOUNDS[all]='[[{(<,.:?/%$!a-zA-Z0-9]'
  AUTOPAIR_RBOUNDS[quotes]='[a-zA-Z0-9]'
  AUTOPAIR_RBOUNDS[braces]=''

  For example, if $AUTOPAIR_LBOUNDS[braces]="[a-zA-Z]", then braces ({([) won't be autopaired if the cursor follows an alphabetical character.

  Individual delimiters can be used too. Setting $AUTOPAIR_RBOUNDS['{']="[0-9]" will cause { specifically to not be autopaired when the cursor precedes a number.
