flex 2.6.14

Noteworthy changes in release 2.6.14 (2026-11-15) [stable]

scanner

• After yyless() gives text back, the scanner now works out whether it is
  at the start of a line from the text that is left. When the text kept
  ends in a newline, a rule that starts with ^ can match what follows.
  With yyless(0), the scanner is back at the line state it had before
  the match. Before, the scanner kept the line state of the whole token,
  and such a rule did not match. (#452)

  Thanks to Todd C. Miller.

• yyinput() no longer overwrites the characters it reads with NUL
  bytes. A program that gave the scanner its own buffer with
  yy_scan_buffer() found those characters gone from its buffer
  afterwards. As a string, yytext now extends over the characters
  that yyinput() has read, and yyleng, the length of the token, is
  unchanged. (#396, #395)

  Thanks to Satya Das.
