This TIP proposes extending the implementation of the $textwidget search subcommand to allow matching of both exact strings and regexp patterns which span multiple lines.
If the string/pattern given to the search subcommand contains sub-strings/patterns which match newlines, then it will be possible for that command to return a match which spans multiple lines. Where a match could occur both within a single line and across multiple lines, the first such match will be found, and the length of the match will follow the usual regexp rules, as documented in the regexp man page.
This should be able to be implemented reasonably efficiently, given the TCL_REG_CANMATCH flag supported by the regexp library, with no impact at all on the speed of matching single lines.
No additional flags or options are required, so there is no visible change to the Tcl language (beyond a minor change to the text widget man page to remove the "single line" caveat)
There is as yet no reference implementation.
