Overview

Checks for redundant ‘source_range`.

Examples:


# bad
node.source_range.source

# good
node.source

# bad
add_offense(node) { |corrector| corrector.replace(node.source_range, prefer) }
add_offense(node) { |corrector| corrector.insert_before(node.source_range, prefer) }
add_offense(node) { |corrector| corrector.insert_before_multi(node.source_range, prefer) }
add_offense(node) { |corrector| corrector.insert_after(node.source_range, prefer) }
add_offense(node) { |corrector| corrector.insert_after_multi(node.source_range, prefer) }
add_offense(node) { |corrector| corrector.swap(node.source_range, before, after) }

# good
add_offense(node) { |corrector| corrector.replace(node, prefer) }
add_offense(node) { |corrector| corrector.insert_before(node, prefer) }
add_offense(node) { |corrector| corrector.insert_before_multi(node, prefer) }
add_offense(node) { |corrector| corrector.insert_after(node, prefer) }
add_offense(node) { |corrector| corrector.insert_after_multi(node, prefer) }
add_offense(node) { |corrector| corrector.swap(node, before, after) }
