Expand description
The high-level intermediate representation for a word-boundary assertion.
A matching word boundary assertion is always zero-length.
Variants§
Unicode
Match a Unicode-aware word boundary. That is, this matches a position where the left adjacent character and right adjacent character correspond to a word and non-word or a non-word and word character.
UnicodeNegate
Match a Unicode-aware negation of a word boundary.
Ascii
Match an ASCII-only word boundary. That is, this matches a position where the left adjacent character and right adjacent character correspond to a word and non-word or a non-word and word character.
AsciiNegate
Match an ASCII-only negation of a word boundary.
