From d2f759a1d4c8a42db73ac62cb8317847a1b40249 Mon Sep 17 00:00:00 2001 From: Robin Haberkorn Date: Fri, 4 Apr 2025 03:36:17 +0300 Subject: scroll caret __almost__ always automatically after key presses * The old heuristics - scroll if dot changes after key press - turned out to be too simplistic. They broke the clang-format macro (M#cf), which left the view at the top of the document since the entire document is temporarily erased. Other simplified examples of this bug would be: @^Um{[: HECcat$ ]:} Mm Or even: @^Um{[: H@X.aG.a ]:} Mm * Actually, the heuristics could be tricked even without deleting any significant amount of text from the buffer. The following test case replaces the previous character with a linefeed in a single key press: @^Um{-DI^J$} Mm If executed on the last visible line, dot wouldn't be scrolled into the view since it did not change. * At the same time, we'd like to keep the existing mouse scroll behavior from fnkeys.tes, which is allowed to scroll dot outside of the visible area. Therefore, dot is scrolled into view always, except after mouse events. You may have to call SCI_SCROLLCARET manually in the ^KMOUSE macro, which is arguably not always straight forward. * Some macros like M#cf may still leave the vertical scrolling position in unexpected positions. This could either be fixed by eradicating all remaining automatic scrolling from Scintilla or by explicitly restoring the vertical position from the macro (FIXME). * This was broken since the introduction of mouse support, so it wasn't in v2.3.0. --- doc/sciteco.7.template | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'doc/sciteco.7.template') diff --git a/doc/sciteco.7.template b/doc/sciteco.7.template index 2a97c02..d5fc4af 100644 --- a/doc/sciteco.7.template +++ b/doc/sciteco.7.template @@ -308,6 +308,10 @@ This will not be delivered on Curses unless bit 7 (64) is set in the You can use \fBEJ\fP with negative keys to retrieve the event type, mouse coordinates and other information about the last mouse event. +Dot is \fInot\fP automatically scrolled into the view when processing +mouse events, so you can customize scrolling and even have dot leaving the +visible area. +You can manually scroll dot into the view by calling \fBSCI_SCROLLCARET\fP. .TP .BI ^K x Any other key with printable representation and all control codes -- cgit v1.2.3
