live syntax-highlighting for the Pry REPL

The pry-coolline plugin provides live syntax highlighting for the Pry REPL for Ruby 1.9.2+ (MRI).

It makes use of the coolline gem and the io/console library.

How to use:

After installing pry-coolline just start Pry as normal, the coolline plugin will be detected and used automatically.

Features

Automatic Ruby syntax highlighting

This is the main feature. It is enabled by default, as long as Pry.config.color is true.

Matching of opening and closing parentheses and brackets

pry-coolline allows to match parentheses and brackets automatically. This behavior can be configured and disabled altogether:

# Whether or not to enable this feature. Defaults to true.
Pry.config.coolline_paren_matching = false

# Change the color code inserted when paprens are (mis)matched.
Pry.config.coolline_matched_paren    = "\e[42m"
Pry.config.coolline_mismatched_paren = "\e[41m"

# In case you can't remember ANSI color codes ;)
require 'term/ansicolor'
Pry.config.coolline_matched_paren    = Term::ANSIColor.on_green
Pry.config.coolline_mismatched_paren = Term::ANSIColor.on_red

Limitations

  • No Ruby < 1.9.2 support.
  • MRI only.
  • Poor support for long lines.
  • Pry's automatic indent is not yet compatible.
  • Occasionally has some quirks (hopefully ironed out in future).
