Overview

This cop checks for ambiguous regexp literals in the first argument of a method invocation without parentheses.

Examples:


# bad

# This is interpreted as a method invocation with a regexp literal,
# but it could possibly be `/` method invocations.
# (i.e. `do_something./(pattern)./(i)`)
do_something /pattern/i

# good

# With parentheses, there's no ambiguity.
do_something(/pattern/i)

Constant Summary collapse

MSG = 
'Ambiguous regexp literal. Parenthesize the method arguments ' \
"if it's surely a regexp literal, or add a whitespace to the " \
'right of the `/` if it should be a division.'
