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?
