Phase 2 abgeschlossen: Bytecode, TBVM, Runtime-Scheibe, tbc run
- Sema zum Lowering-Pass umgebaut: typisiertes HIR (Slots, explizite Konvertierungsknoten) als Codegen-Eingabe; BYREF verlangt exakten Typ - Bytecode-Feindesign umgesetzt: monomorpher Opcode-Satz, .tbc-Container (Formatversion 1) mit eigenem Writer/Reader - Codegenerator HIR -> Bytecode (Fixup-Listen, keine globalen Passes) - TBVM-Interpreter: Kontrollfluss, GOSUB-Stack je Frame, BYREF/BYVAL, STATIC, DEF FN, DATA/READ/RESTORE, ON [LOCAL] ERROR/RESUME/ERR/ERL, Breakpoints/Einzelschritt/Inspektion, STOP fortsetzbar - Runtime-Scheibe: Host-Trait (Konsole/Capture), Builtin-Tabelle, Konvertierungsmatrix, PRINT-Formatierung/Druckzonen, Stringfunktionen - tbc run/build/check mit Exit-Codes nach Entscheidung D6 - Korpus-Harness (byte-genauer Vergleich) + 3 neue Korpusdateien (konvertierung, fehlerbehandlung, byref); 137 Tests gruen - Benchmarks: Einzelmodul 1,2 ms / Projekt 49.760 Zeilen 124 ms (Budgets eingehalten), VM ~5 Mio Schleifeniterationen/s - Doku fortgeschrieben (tbvm-design, sprachreferenz, PLAN); verlagerte Punkte als explizite Aufgaben in Phase 3 - OpenSpec-Change phase-2-bytecode-vm (27/27 Tasks) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

//! `tbc` — Standalone-Compiler von Terminal Basic.
|
||||
//!
|
||||
//! Wandelt Quelldateien und Projekte in binäre Ergebnisse (`.tbc`-Bytecode
|
||||
//! bzw. eigenständig ausführbare Programme) um. Geplante Unterbefehle
|
||||
//! (siehe PLAN.md):
|
||||
//! - `tbc build <projekt|datei.bas>` Kompilieren zu binärem Ergebnis
|
||||
//! - `tbc run <datei.bas>` Kompilieren und sofort ausführen
|
||||
//! - `tbc check <datei.bas>` Nur Syntax-/Semantikprüfung
|
||||
//! Unterbefehle (Phase 2):
|
||||
//! - `tbc run <datei.bas>` Kompilieren und sofort ausführen
|
||||
//! - `tbc build <datei.bas>` Kompilieren zu `datei.tbc`
|
||||
//! - `tbc check <datei.bas>` Nur Syntax-/Semantikprüfung
|
||||
//!
|
||||
//! Exit-Codes von `run` (Entscheidung D6, docs/tbvm-design.md):
|
||||
//! 0 = END/SYSTEM/Programmende · 3 = STOP · 2 = Laufzeitfehler ·
|
||||
//! 1 = Compile-Fehler/Bedienfehler.
