From eee669a76b3c0b1928475d55d9e1333b3d15bb8c Mon Sep 17 00:00:00 2001 From: Robin Haberkorn Date: Fri, 25 Jul 2025 01:41:37 +0300 Subject: implemented the <^A> command for printing arbitrary strings * Greatly improved usability as a scripting language. * The command is in DEC TECO, but in contrast to DEC TECO, we also support string building constructs in ^A. * Required some refactoring: As we want it to write everything verbatim to stdout, the per-interface method is now teco_interface_msg_literal() and it has to deal with unprintable characters. When displaying in the UI, we use teco_curses_format_str() and TecoGtkLabel functions/widgets to deal with possible control codes. * Numbers printed with `=` have to be written with a trailing linefeed, which would also be visible as a reverse "LF" in the UI. Not sure whether this is acceptable - the alternative would be to strip the strings before displaying them. * Messages written to stdout are also auto-flushed at the moment. In the future we might want to put flushing under control of the language. Perhaps :^A could inhibit the flushing. --- src/qreg.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/qreg.h') diff --git a/src/qreg.h b/src/qreg.h index 27a3653..2b970aa 100644 --- a/src/qreg.h +++ b/src/qreg.h @@ -45,6 +45,8 @@ extern teco_view_t *teco_qreg_view; * teco_qreg_set_integer_t set_integer; * ... * teco_qreg_set_integer(qreg, 23, error); + * + * But this probably won't work.
