THE STACK: INLANG + CREPUSCULARITYUltrafast compiler pipeline for OOP and systems languages
A single unified Core IR → MIR → native JIT emitter. No LLVM, no bytecode VM. Experience sub-millisecond compile loops, live code injection, and seamless GUI integration using the inlang (.in) systems language coupled with crepuscularity for hardware-accelerated declarative UI everywhere.

PIPELINE CAPABILITIES
1. Multi-Frontend Parser
Uses Tree-sitter polyglot fronts to ingest Swift, C, Rust, Go, Python, Zig, and Java. Lowers source files directly into a unified Core IR AST, mapping structural semantics cleanly.2. MIR & Offset Assembly
Translates Core IR to MIR (Mid IR). MIR defers relative address offsets, performing label resolution and instruction alignment before assembling to binary buffers.3. Native JIT Emitters
Direct machine code emission for AArch64 (ARM64) and x86_64. Native page allocation maps binary targets to executable memory, running JIT compiles in microseconds.DOCUMENTATION DIRECTORY
