A cross-platform "virtual terminal" (VT) manipulation library.
Termina works on Windows as well as *NIX, but Windows requires some extra thought to choose the preferred way of handling input.
Termina is a cross between Crossterm and TermWiz with a lower level API which exposes escape codes to consuming applications. The aim is to scale well in the long run as terminals introduce VT extensions like the Kitty Keyboard Protocol or Contour's Dark/Light mode detection - requiring minimal changes in Termina and also allowing flexibility in how applications detect and handle these extensions. See examples/event-read.rs for a look at a basic API.
Termina is able to "speak text/VT" on Windows. This is made possible by Microsoft's investment into ConPTY. This means that this input mode requires 64-bit Windows 10.0.17763 (released around Fall 2018) or later (same as WezTerm). However, using VT mode on Windows means the terminal you use needs to support the Kitty Keyboard Protocol in order to handle some complex key combinations. Windows Terminal, notably, does not implement this protocol. However, using the VT protocol allows for some newer features to work, such as bracketed paste. This means there is no single answer for which protocol to use - it depends on your use case.
See feature comparison below.
| VTE Mode | Legacy Console Mode | |
|---|---|---|
| Kitty Keyboard Protocol | ✓ | ✕ |
| Extended key events | terminal-dependent (must support Kitty Keyboard Protocol) | ✓ |
| Bracketed paste | ✓ | ✕ |
| AltGr Support | ✓ | ✕ |
The legacy input reader can be used by enabling the windows-legacy feature. See the event-read example for usage.
