- This program provides a scroll back buffer for a terminal like st(1). It
- should run on any Unix-like system.
-
- At the moment it is in an experimental state. Its not recommended for
- productive use.
-
- The initial version of this program is from Roberto E. Vargas Caballero:

-
- What is the state of scroll?
-
- The project is faced with some hard facts, that our original plan is not doable
- as we thought in the first place:
-
- 1. [crtl]+[e] is used in emacs mode (default) on the shell to jump to the end
- of the line. But, its also used so signal a scroll down mouse event from
- terminal emulators to the shell an other programs.
-
- - A workaround is to use vi mode in the shell.
- - Or to give up mouse support (default behavior)
-
- 2. scroll could not handle backward cursor jumps and editing of old lines
- properly. We just handle current line editing and switching between
- alternative screens (curses mode). For a proper end user experience we
- would need to write a completely new terminal emulator like screen or tmux.
-
- What is the performance impact of scroll?
-
- indirect OpenBSD
