Type of assertions

Variants

StartText

Start of input text

EndText

End of input text

EndTextIgnoreTrailingNewlines

End of input text, or before any trailing newlines at the end (Oniguruma’s \Z)

Fields

crlf: bool

Whether CRLF mode is enabled. If true, trailing \r\n pairs (in addition to bare \n) are also ignored.

StartLine

Start of a line

Fields

crlf: bool

CRLF mode. If true, this assertion matches at the starting position of the input text, or at the position immediately following either a \r or \n character, but never after a \r when a \n follows.

StartLineOniguruma

Start of a line in Oniguruma mode. Behaves like Assertion::StartLine, but additionally rejects matches at the end of the input when it is preceded by a newline.

Fields

crlf: bool

CRLF mode. If true, this assertion matches at the starting position of the input text, or at the position immediately following either a \r or \n character, but never after a \r when a \n follows.

EndLine

End of a line

Fields

crlf: bool

CRLF mode If true, this assertion matches at the ending position of the input text, or at the position immediately preceding either a \r or \n character, but never after a \r when a \n follows.

LeftWordBoundary

Left word boundary

LeftWordHalfBoundary

Left word half boundary

RightWordBoundary

Right word boundary

RightWordHalfBoundary

Right word half boundary

WordBoundary

Both word boundaries

NotWordBoundary

Not word boundary
