Release notes#

Two-day release spanning 39 commits — a compact burst focused on nanus (a new Faber compiler prototype), unifying binding syntax under const/var, revamping the CLI annotation toolkit, adding rivus run/rivus fetch, and cleaning up the import/collection DSL.

Scale#

Major tracks#

nanus: minimal Faber compiler prototype#

A new TypeScript compiler (~2.2k lines) targeting the 84 features rivus actually uses (vs. faber's 139). The prototype was progressively extended across several commits in this release.

• Add minimal Faber compiler prototype (fons/nanus/) with AST, lexer, parser, emitter, and CLI (5e7bde28d)
• Extend parser for rivus compatibility: import resolution, loop/cura/ergo parse, annotation support (5e95fbc38)
• Add triple-quote (""") multi-line strings with leading/trailing newline stripping and type-first variable declarations (fixum ignotum name), then rewrite rivus/cli.fab from declarative to procedural style using @ externa + process.argv (89fc1d4c5)
• Complete rivus compilation support — all 135 files compile (b389971fa)
• Fix multiple codegen improvements: @ publica extern functions, ambient externa declarations, quidlibet → any mapping, operator precedence fixes (52d86e6b3)
• Add README documenting nanus purpose, architecture, and key design decisions (071b43c12)

fixum/varia binding unification#

Replaced pro/fit/fiet across all binding contexts with const (immutable) and var (mutable), making mutability explicit in loop bindings, cura bindings, and variable declarations. The old fit/fiet/fiunt/fient keywords are removed from binding contexts (async returns deferred).

• Mass replace pro with const across 69 rivus source files (975fc2659)
• feat(rivus): Unify binding expressions with const/var in loops, cura, and AST — add mutabilis field, codegen let/const (c1ef07dea)
• feat(faber): Same unification in faber parser, AST, and codegen (85718c903)
• Support array destructuring in bindings (492d5fa88)

CLI annotation toolkit#

A coordinated faber+rivus change set introducing @ optio with boolean flag support, @ operandus ceteri for variadic positional arguments, and optiones <name> bundles that produce Map<string, string>.

• feat(rivus): Parse CLI annotations: @ optio, @ operandus (b6fd0ec2e)
• feat(rivus): Add new @ optio syntax and optiones modifier (2e1248aa3)
• feat(cli): @ operandus ceteri (variadic args) and optiones bundle for subcommands — help generates [files...] notation (abc657d66)

rivus run / fetch commands#

• Add rivus run for § scriptum build scripts — on-demand compilation to TS and execution via Bun (e8b789696)
• Add rivus fetch for GitHub dependency caching — resolves git refs to SHAs, downloads tarballs to ~/.cache/faber/, content-addressed dedup, --force and --json flags (27c53b22a)

rivus language fixes#

• Normalize visibility annotations to @ publica (replaces @ publicum/@ publicus) (edd652606)
• Remove ref keyword from novum expressions — novum Foo { } not novum Foo de { } (061b71105)
• Replace secus si with elif (closes #244) (19c206f88)
• Fix else/default to require braces or ergo — prevents ambiguous fallback branches; add parser errors P108 and P109 (b5f9ac2c9)
• Simplify CLI entry to incipit {} (closes #242) (364aaa799)
• Add exitus modifier for CLI exit codes (closes #243) (793eee391)
• Stream-first stdin for parse and check commands (47198a2ce)
• Stream-first stdin and emit --strict mode (e450392b4)
• Disambiguate for-of loop from destructure in parser (23e584899)

Other changes#

• § dependentia alias-based import resolution — enables dependency aliases declared via annotations, adds Dependentia type and resolveDependentiaPath (15dd88f29)
• Add --manifest flag for project manifest support (closes #210) (df89bb9c0)
• Latinize fetch module identifiers (9db22f48b)
• Consolidate collection DSL under ab, remove from DSL transforms — ab gains ordina, collige, grupa, max/min/medium/numera with ascendens/descendens direction support (closes #216) (4a3d8c8dd)
• Remove bare ex...importa syntax — imports now require § prefix (closes #218) (2bc05f09a)
• Drop magic path resolution in faber codegen — when keepRelativeImports=true, preserve all paths as-is for portable emitted output (closes #234) (4ab66b378)
• Add --verbose flag to build commands to show subprocess output (3b44ebaf3)
• Add typecheck step to build:faber before compilation (b6cc1600c)
• Refactor build: target-suffixed binaries and output directories (5fe2244e8, 3e5ba601e)
• Use rivus emit command for artifex compilation (9c1bd4583)
• Fix faber for-of loop disambiguation after const/var (17a9e960c)
• Fix rivus API usage in minimal entry point (6bfa28c6a)
• Refactor rivus: separate CLI from core, add minimal entry point (231b12aba)
• Replace array destructuring in loop with explicit bindings (bd52016ba)
