Enum TerminalType 

pub enum TerminalType {
    WindowsTerminal,
    Wsl,
    WindowsConsole,
    MacOsTerminal,
    LinuxNative,
    Unknown,
}

Terminal type detection for viewport handling

Different terminals report their dimensions differently:

• Some report the visible viewport size (what the user sees)
• Others report the buffer size (which can be larger, enabling scrollback)

This enum categorizes terminals based on their reporting behavior.

Variants

WindowsTerminal

Windows Terminal - reports viewport size correctly

Wsl

WSL (Windows Subsystem for Linux) - may report buffer size

WindowsConsole

PowerShell / cmd - reports buffer size (not viewport)

MacOsTerminal

macOS Terminal.app

LinuxNative

Ubuntu native terminal (gnome-terminal, etc.)

Unknown

Unknown terminal - use conservative defaults

Implementations

impl TerminalType

pub fn detect() -> Self

Detect the terminal type from environment variables

Uses environment variables to identify the terminal emulator:

• WT_SESSION: Windows Terminal
• WSL_DISTRO_NAME: WSL environment
• TERM_PROGRAM: macOS Terminal.app or other
• Platform detection for fallback

pub const fn viewport_height_offset(self, reported_height: u16) -> u16

Calculate viewport height offset based on terminal type

Returns the number of rows to subtract from the reported terminal size to get the actual visible viewport. This compensates for terminals that report buffer size instead of viewport size.

Arguments

• reported_height - The height reported by the terminal

Returns

The number of rows to subtract to get the visible viewport height

pub const fn name(self) -> &'static str

Get a human-readable name for this terminal type

Trait Implementations

impl Clone for TerminalType

fn clone(&self) -> TerminalType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TerminalType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TerminalType

fn eq(&self, other: &TerminalType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
