        # StringScanner.skip

(from ruby core)
---
    skip(pattern)

---

Attempts to skip over the given `pattern` beginning with the scan
pointer. If it matches, the scan pointer is advanced to the end of the
match, and the length of the match is returned.  Otherwise, `nil` is
returned.

It's similar to #scan, but without returning the matched string.

    s = StringScanner.new('test string')
    p s.skip(/\w+/)   # -> 4
    p s.skip(/\w+/)   # -> nil
    p s.skip(/\s+/)   # -> 1
    p s.skip("st")    # -> 2
    p s.skip(/\w+/)   # -> 4
    p s.skip(/./)     # -> nil
