g_anchor_scanning

↪️ Iterative Matching with \G Anchor

Use the \G anchor to resume regex matching at the end of the previous match, ideal for stateful scans. Combine with String#scan or manual loops for incremental parsing.

str = '1,2,3'
pattern = /(?:\G,?)(\d+)/
numbers = []
str.scan(pattern) { |num| numbers << num[0].to_i }
# numbers => [1, 2, 3]
