The previous commit added the option to convert the storage to the cluster format. That saves memory as rows are moved to scrollback, but makes scrolling back more expensive due to that conversion. This commit adds a fast(ish) path for the common case of simply appending text to a new line before it gets scrolled: the default format for lines in the screen is now the cluster format and, provided that the cursor moves from left to right as text is emitted, can simply append to the cluster storage in-place and avoids a conversion when the line is moved to scrollback. This improves the throughput of `time cat enwiki8.wiki` so that the runtime is typically around 11-12s (compared to 9-10s before introducing cluster storage). However, this is often a deal of variance in the measured time and I believe that that is due to the renderer triggering conversions back to the vec storage and introducing slowdowns from the render side. That's what I'll investigate next. |

Terminal Wizardry
This is a rust crate that provides a number of support functions for applications interested in either displaying data to a terminal or in building a terminal emulator.
It is currently in active development and subject to fairly wild sweeping changes.
Included functionality:
Surfacemodels a terminal display and its componentCells- Terminal attributes are aware of modern features such as True Color, Hyperlinks and will also support sixel and iterm style terminal graphics display.
Surfaces include a log ofChanges and an API for consuming and applying deltas. This is a powerful building block for synchronizing screen instances.- Escape sequence parser decodes inscrutable escape sequences and gives them semantic meaning, making the code that uses them clearer. The decoded escapes can be re-encoded, allowing applications to start with the semantic meaning and emit the appropriate escape sequence without embedding obscure binary bytes.
Capabilitiesallows probing for terminal capabilities that may not be included in the system terminfo database, and overriding them in an embedding application.Terminaltrait provides an abstraction over unix style ttys and Windows style console APIs.Changes fromSurfacecan be rendered toTerminals.Terminals allow decoding mouse and keyboard inputs in both blocking or non-blocking mode.Widgettrait allows composition of UI elements at a higher level.LineEditorimplements shell-like line editing functionality.
Windows Support
Termwiz understands how to work with both the legacy console APIs and the new PTY and virtual terminal features available in Windows 10, allowing for true color terminal applications on Windows 10.
