RuboCop
AST¶ ↑
Contains the classes needed by RuboCop to deal with Ruby's AST, in particular:
This gem may be used independently from the main RuboCop
gem. It was extracted from RuboCop
in version 0.84 and its only dependency is the parser gem, which rubocop-ast
extends.
Installation¶ ↑
Just install the rubocop-ast
gem
gem install rubocop-ast
or if you use bundler put this in your Gemfile
gem 'rubocop-ast'
Usage¶ ↑
Refer to the documentation of {RuboCop::AST::Node
} and {RuboCop::AST::NodePattern
}
See the docs site for more details.
Parser compatibility switches¶ ↑
This gem, by default, uses most legacy AST output from parser, except for the following which are set to true
: * emit_forward_arg
* emit_match_pattern
The main RuboCop
gem uses these defaults (and is currently only compatible with these), but this gem can be used separately from RuboCop
and is meant to be compatible with all settings. For example, to have -> { ... }
emitted as LambdaNode
instead of SendNode
:
RuboCop::AST::Builder.emit_lambda = true
