Virtual Terminal Emulator & VT100 Parser

A terminal emulation engine for building command-line user interfaces, REPLs, and embedded terminal widgets. Implements full VT100/VT220/xterm escape sequence parsing, 24-bit TrueColor support, and pty spawning.

Parser ModelPaul Flo Williams State Machine

Color Depth24-bit TrueColor (RGB)

PTY SupportConPTY & OpenPTY

MilestoneActive Module

Protocol & Wire Format Architecture

Zero-Heap Allocation Primitives

Deterministic Memory

Buffer allocations are bound to caller lifecycle with zero heap fragmentation

RFC Wire Conformance

Strict binary packet layout and protocol compliance written in pure Kale

Monorepo Integration

Instantly consumable by Compiler, Editor, and Bare-Metal targets

Architecture Contract

High-Throughput Systems Foundation

Engineered to maximize CPU instruction pipelining and data cache locality. Every algorithm avoids heap pointer indirection wherever contiguous stack or arena buffers can be employed.

Verification: 138/138 Regression Suite Pass

Signed commit governance • Strict type safety

kale

import "libs/term/emulator.kl" as term;

fn main() -> int32 {
    let term_emu: term.Emulator = term.create_emulator(80, 24);
    term.feed_bytes(&term_emu, "\x1b[38;2;185;28;28mImperial Crimson Text\x1b[0m\n");
    term.render_to_viewport(&term_emu);
    return 0;
}

Compilation & Linker Directives

Deterministic command-line invocations to build, link native dynamic dependencies, and run automated regression tests:

$kale build tests/test_term.kl -o bin/test_term.exe

$./bin/test_term.exe

Monorepo Governance

GPG Key 1B917D4779A6102E • Continuous integration with automated symbol verification.

Architectural Capabilities

Finite State Machine Parser

Handles complex CSI, OSC, and DCS escape sequences reliably without buffer overflows.

Cell Grid Matrix

Two-dimensional character cell buffer tracking glyphs, foreground/background colors, underline, bold, and italic attributes.

Pty Bridge

Seamlessly launches child shells (cmd, powershell, bash) and bridges stdin/stdout to terminal buffers.
