Patch go get DECSTBM on par with xterm (665 bytes, patch)
2005-06-10 08:53 UTC, Michele Baldessari 		none Details | Review

Description Keith Packard 2004-10-18 04:42:08 UTC 
Examine xterm code where DECSTBM forces cursor position to 0,0 whenever it is
invoked.

Note that gnome terminal doesn't move the cursor in this case.
Comment 1 Mariano Suárez-Alvarez 2004-10-31 11:06:12 UTC 
Neither the manual for vt102 nor for the one for the vt220 says DECSTBM does
this; the one for the 510 does.

Moving to vte. This is trivially done in vte.c:vte_sequence_handler_cs.
Comment 2 Kjartan Maraas 2005-02-15 10:25:16 UTC 
Trivially enough to create a patch for it? :-)

Patch go get DECSTBM on par with xterm

This is a patch that brings DECSTBM on par with xterm.
Comment 4 Chris Wilson 2007-01-31 23:18:26 UTC 
Confirmed that xterm does indeed handle it this way.

	Bug 155687 – Scroll region \E[NN;MMr should set cursor to home

	Patch originally by Michele Baldessari.

	* src/vteseq.c: (vte_sequence_handler_cs):
		Move the cursor to (0,0) rather than clamping the cursor to 
		be inside the scroll region.
