The main repo for the Medley Interlisp project. Wiki, Issues are here. Other repositories include maiko (the VM implementation) and Interlisp.github.io (web site sources)
This includes updates to all core Tedit files, plus minor updates for compatibility to TMAX and a few other separate applications. This supercedes the draft PR #1673.
What this includes:
More work on eliminating Xpointers through TEXTOBJ and SELECTION (still a bit more to do).
Performance improvements in line updating when typing and especially printing (important slow case remains: printing at the end of the stream, e.g. for transcript/dribble applications)
Fixed glitches in transitions between fat XCCS characters on either side of image objects
Scrolling improvements
Fewer line-update subroutines, for maintainability
Better caret placement with keyboard input
Better line and caret placement at bottom of pane and end of document, with or without EOL's
Fix #1677 (offscreen on left)
Better behavior when reshaping
New functionality
meta-d/D brings up DINFO man page, like Sedit, for a selected word (a "word" is an atom according to the reader environment, if seeing a Lisp source file or function) #1739
meta-o/O opens an Sedit, if possible, for a selected word also #1739
READONLY property can have value QUIET instead of just T: Still ignores attempted changes but doesn't put up a warning message #1738. Perhaps useful for applications like hexdump (@pamoroso )
New property APPEND: allows updates only at the end of the stream, FWIW.
Changed behavior:
Textstream BOUT now behaves like BOUT (and printing) to other output streams: appends at the end, replaces in the middle. #1740, also #1701.
BOUT also doesn't create a history event--not undoable. There is some discussion of this in #1701, and this can be adjusted or conditioned on a property. E.g. only make the last 100 BOUT's undoable, like the exec's history list. But BOUTing is really something that programs do, typically not related to user-interface inputs.
(I'm marking this as Draft for now, but please try it. I'll add more comments if I think of more things to mention.)
