pisces ☯ 双鱼

pisces ['paɪsiz] is a plugin for fish that helps you to work with paired symbols like () and '' in the command line. Similar to your favorite text editor!

Features

Here | denotes the current cursor position. No manual cursor motion involved :sparkles:

• autocloses pair symbol: ... | + <kbd>(</kbd> ⇒ ... (|)
• skips the closing symbol: ...|) + <kbd>)</kbd> ⇒ ... )|
• removes empty pairs: ...([|]) + <kbd>backspace</kbd> ⇒ ...(|) + <kbd>backspace</kbd> ⇒ ...|
• the set of pairs is configurable (see below)

Installation

The minimum recommended version of fish is v2.6, because

• it has a feature called bracketed (a.k.a safe) paste which solves the problem with pasting strings containing paired symbols (they get autoclosed), see #6 for details.

The minimum required version of fish is v2.3, because

• there was a bug #2210 in v2.2 which would brake quotes handling
• it uses string builtin which was introduced in v2.3

• Using Fisher:

  fisher install laughedelic/pisces
  

• Using oh-my-fish:

  omf install pisces
  

  Notice that you will need to restart fish to get this new installation working. This is specific to the way oh-my-fish handles installation.

Configuration

Only completing at the end of the line

To disable completing pairs unless the cursor is at the end of the line, set the $pisces_only_insert_at_eol variable:

set -U pisces_only_insert_at_eol 1

Changing the set of pairs

You can set the $pisces_pairs universal variable and launch a new fish session to reload key bindings:

set -U pisces_pairs $pisces_pairs '<,>' '`,`' '«,»'

Note that at the moment pisces works correctly only with single-symbol delimiters.

The default set of pairs:

• (,) parenthesis
• [,] brackets
• {,} braces
• "," double quotes
• ',' single quotes
