|Subject: [PATCH] st: alternative scrollback using ring buffer and view offset
|
|Implement scrollback as a fixed-size ring buffer and render history
|by offsetting the view instead of copying screen contents.
|Implement reflow of history and screen content on resize if it is needed.
|
|Tradeoffs / differences:
|  - Scrollback is disabled on the alternate screen
|  - Simpler model than the existing scrollback patch set
|  - Mouse wheel scrolling enabled by default
|  - Shift + page up/down and shift + end/home work as well.
|  - When using vim, mouse movement will no longer move the cursor.
|  - There can be visual artifacts if width of the window is shrank to the
|    size smaller than the shell promp.
|  - Mouse selection is persistent even if it goes off screen but it get
|    reset on resize.
