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.
- Install the gem:
gem install pry-coolline - See the source code
How to use:
After installing pry-coolline just start Pry as normal, the coolline
plugin will be detected and used automatically.
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
- 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).
