Release notes#

Post-hoc release note spanning 67 commits. v0.1.0 has no tag — the tag series starts here — so the base is the repository's first commit (664d7a659, 2025-12-20, "Initial project setup"). Range: 664d7a659..v0.2.0, 2025-12-20 → 2025-12-22.

Headline: first tagged checkpoint of the Faber Romanus era — a TypeScript/Bun compiler bootstrapped over three days: lexicon with declension support, tokenizer, parser, semantic analysis with type resolution, and TS/Zig/WASM codegen, all behind a Latin-keyword language surface that was still in rapid flux (extension src→fons, .la→.fab, type-first→arrow return types all changed inside this range).

Scale#

¹ Conventional prefixes were not yet in use; every subject is a bare imperative verb. Leading-verb signal: 35 Add/Added, 6 Fix, 4 Implement, 4 Complete, 3 Update, 15 other.

Major tracks#

Architecture and syntax bootstrap#

• Records the initial architecture decisions (ADR-001 through ADR-005) in docs/decisions.md (0577ce88e), the syntax-sketch decisions (41c924122), complete control-flow syntax (e0d00ada4), and the lexicon design document (33750e07b).

Compiler pipeline (TypeScript/Bun)#

• Adds the lexicon module with tests (25b5fd0d2) and built-in types with complete declension support (396148872).
• Implements the tokenizer (10a64cf30), parser (8902b097d), and code generator plus CLI (261cf8569).
• Adds a semantic-analysis phase with type resolution — src/semantic/ (index.ts 759 lines, scope.ts, types.ts) with a 257-line test suite (4b6e6bd26).
• Fixes the run command and maps write to console.log (29ba362d5).

Multi-target codegen: TS, Zig, WASM#

• Adds dual codegen (TS + Zig) and renames the source extension to .la (0bae43f63), with a later rename to .fab when the Zed extension lands (db84800c3).
• Adds WASM as a third compilation target — a 759-line src/codegen/wasm.ts (0e3bfda36).
• Adds comprehensive codegen tests and updates the Zig target (4aa219cd9); fixes Zig codegen (output validation fa47b8d82, later issue fixes 6510e75c5) and assert codegen braces for ESLint compliance (5e1aaffbb).

Language surface#

• Migrates to type-first syntax with an expanded type system (45ab626c0), then changes function return types from type-first to arrow syntax (4a92ff996).
• Makes types and keywords case-insensitive with lowercase canonical forms (8801b4ebf, c58dafc46).
• Adds array literals (2c8913a2a), object literals (d17b7d77a), and object destructuring (ec1dfef43).
• Changes for-loop syntax to source-first ex/in ... pro (384e5703a) and adds range syntax with a per-step form: 0..10 per 2 (2a1d901e2).
• Adds control-flow statements: adfirma assertion (652d57733), custodi guard (bcf394c56), elige/si switch (f73e39d4b), cum with-blocks (d49bd6551), and ergo one-liners for if/aliter (7c99020aa) and loops (c9aa89580).
• Adds write as a statement keyword, fixing the switch ergo parser bug (032d30e17) and write global plus ergo switch syntax (134ae36e2).
• Adds nulla/nonnulla empty/non-empty operators (3253a67cb).
• Adds an intrinsics layer and the norma stdlib written in Faber (1c2902314), then underscores all intrinsics for consistency (c9c1050c3).

Lexicon and Latin keyword surface#

• Refines the verb lexicon around a Unix command philosophy (9b3e0e940), adding the 2nd conjugation for stateful operations (19d885e5c) and the 4th conjugation for IO/side-effect operations (b3456ff86).
• Adds OOP/module keywords for cross-target portability (0a3bf2f3c), returns a structured LexiconError instead of null (8e40da11e), removes Res and Functio from types-builtin (daa44eb40), and completes the high-priority lexicon TODOs (a4e185be8).

Editors and tooling#

• Adds Zed syntax highlighting with an in-repo tree-sitter grammar and renames the extension to .fab (db84800c3).
• Adds ESLint with Stroustrup brace style (80ac73af6) and replaces @stylistic with Prettier for code formatting (8054c30c8), with a linter-applied pass (75c7017d0).
• Adds the systems-language developer code standards (0472f3acb) and comprehensive module documentation (f36339c5d).

Build, release, and repo organization#

• Renames directories to Latin: src→fons, examples→exempla (9113c1560); adds scripta/ for package scripts (79f029a6a) and a standalone executable build (bun run build → opus/faber, 3c6b7d9bf).
• Adds the release script (da966fdfc) and ESLint (d6247b081) and Zig build-exe (1455fd481) verification to build:exempla.
• Updates examples to the const keyword (6ed3cc00d) and write statement syntax (c28c27f12); deletes examples/app (5729c1823).
• Adds the comprehensive README (e4f135fc2), the WASM-target architecture README update (fe78436b8), user-defined types documentation (ac3a7e92f), the current-features README update (046560505), and a documentation cleanup pass (e7a15475c).
• Releases v0.2.0: bumps package.json and commits the standalone binary as editiones/faber-0.2.0 (8b2169d19).

Honest limitations#

• Post-hoc note. This document was written after the fact from the git range; no release process or verification record survives from the era. v0.1.0 was never tagged, so the range base is the repository's first commit (664d7a659), not a v0.1.0 boundary.
• No gated test suite. No CI or test gates existed in this range; the closest checks were ESLint, Prettier, and manual build:exempla verification. Test files exist (parser, semantic, codegen, lexicon) but no pass/fail record is in the range.
• Binary committed to the repo. editiones/faber-0.2.0 is a ~60 MB bun-standalone executable committed directly to the tree — an era practice, not a multi-arch release artifact.
• Rapidly moving language. Keyword surface, syntax, file layout, and even the source extension changed within this range. Nothing here is a stability promise.
• WASM target depth. wasm.ts landed near the end of the range; its coverage at v0.2.0 is unverified from this range alone.
• Classification caveat. Without conventional prefixes, the Scale table's feat/fix/docs/test rows are all zero; the leading-verb counts are the era's only signal.
