🔧 Configure Regex Flags Inline

Inline modifiers (?i), (?m), and (?x) let you switch options on or off for specific parts of your pattern. This keeps flags local and your global settings untouched.

# Case-insensitive for only the 'foo' part
txt = 'Foo Bar'
puts txt.match?(/(?i:foo) bar/)  # => true

# Multiline within a group
doc = "line1
line2"
puts doc.match?(/(?m:^line2$)/)  # => true

Use inline modifiers to avoid side effects on the rest of your pattern.
