# Slovo Slovo (ⰔⰎⰑⰂⰑ) is a typed structural programming language and toolchain. This repository is the canonical public monorepo for the language design, standard library source, compiler, runtime, examples, benchmarks, and technical documents. Current release: `1.0.0-beta.14`. ## Repository Layout ```text compiler/ Glagol, the first Slovo compiler runtime/ C runtime used by hosted native builds lib/std/ source-authored Slovo standard-library facades examples/ compiler-supported Slovo examples and projects benchmarks/ local benchmark comparison harnesses docs/language/ language manifest, specs, roadmap, and release notes docs/compiler/ compiler manifest, roadmap, and release notes docs/papers/ whitepapers and generated publication PDFs scripts/ local release and document tooling ``` ## Beta Scope `1.0.0-beta.14` keeps the `1.0.0-beta` language baseline, includes the `1.0.0-beta.1` tooling/install hardening slice, the `1.0.0-beta.2` runtime/resource foundation bundle, the `1.0.0-beta.3` standard-library stabilization bundle, the `1.0.0-beta.4` language-usability diagnostics bundle, the `1.0.0-beta.5` local package/workspace discipline bundle, and the `1.0.0-beta.6` loopback networking foundation, plus the `1.0.0-beta.7` serialization/data-interchange foundation and the `1.0.0-beta.8` concrete type alias foundation, the `1.0.0-beta.9` collection alias unification and generic reservation slice, the `1.0.0-beta.10` developer-experience API discovery slice, and the `1.0.0-beta.11` local package API documentation slice, plus the `1.0.0-beta.12` concrete vector query and prefix parity slice, the `1.0.0-beta.13` diagnostic catalog and schema policy slice, and the `1.0.0-beta.14` benchmark suite catalog and metadata gate. The language baseline supports practical local command-line, file, and loopback-network programs with: - modules, explicit imports, packages, and local workspaces - `new`, `check`, `fmt`, `test`, `doc`, `symbols`, `build`, `run`, and `clean` - `i32`, `i64`, `u32`, `u64`, `f64`, `bool`, `string`, and internal `unit` - structs, enums, fixed arrays, concrete vectors, option/result families, and current `match` - module-local transparent concrete type aliases - explicit `std/*.slo` imports from `lib/std`, installed `share/slovo/std`, or `SLOVO_STD_PATH` - beta-scoped loopback TCP handles through `std.net` - JSON string quoting and compact JSON text construction through `std.json` - hosted native builds through LLVM IR, Clang, and `runtime/runtime.c` The generated standard-library API catalog is a beta discovery aid: it lists exported helper signatures from `lib/std/*.slo`, normalizes module-local concrete aliases such as `VecI32` and `ResultU64` to their concrete public types, and omits non-exported helpers and `(type ...)` aliases. `glagol symbols ` emits deterministic editor-facing S-expression metadata for modules, imports, exports, aliases, structs, enums, functions, tests, source spans, and workspace package names. `glagol doc -o ` now includes deterministic public API sections for local package and module documentation: exact exported function signatures, exported struct fields, exported enum variants and payload types, non-export filtering, and module-local alias normalization. The `1.0.0-beta.12` vector parity slice adds source-authored helper coverage only: `std.vec_i64` gains `count_of`, `starts_with`, `without_prefix`, `ends_with`, and `without_suffix`, while `std.vec_f64` gains `count_of`. The `1.0.0-beta.13` diagnostics slice documents the beta `slovo.diagnostic` version `1` policy in [`docs/language/DIAGNOSTICS.md`](docs/language/DIAGNOSTICS.md): the S-expression/JSON relationship, required and optional fields, JSON-line discipline, source-less diagnostics, manifest diagnostic metadata, compatibility and migration classes, and the current golden diagnostic code catalog. The `1.0.0-beta.14` benchmark metadata slice documents the existing benchmark suite catalog in [`benchmarks/README.md`](benchmarks/README.md). It explains `python3 benchmarks/runner.py --suite-list` for the human-readable suite inventory and `python3 benchmarks/runner.py --suite-list --json` for beta tooling metadata, with required scaffold-file verification for each current suite. Benchmark timings remain local-machine evidence only; the JSON field set is not a stable public schema. Still deferred before stable: executable generics, maps/sets, broad package registry semantics, stable Markdown schema, stable stdlib/API compatibility freeze, DNS/TLS/async networking, LSP/watch guarantees, SARIF and daemon protocols, stable `1.0.0` diagnostics freeze, re-exports/globs/hierarchical modules, mutable vectors, slice/view APIs, iterators, new compiler-known runtime names, stable ABI and layout, performance claims, stable benchmark JSON metadata schema, and runtime changes for generic collections. The next likely language slice after `1.0.0-beta.14` should continue from the developer-experience, package, benchmark metadata, and reserved generic/collection lanes without claiming executable generics, maps, sets, traits, inference, monomorphization, iterators, ABI stability, runtime changes, LSP/watch protocols, SARIF/daemon protocols, registry semantics, stable Markdown schema, stable benchmark JSON schema, a stable `1.0.0` diagnostics freeze, standard-library/API compatibility freeze, mutable vectors, slice/view APIs, new runtime names, or performance claims until the contract and gates are explicit. ## Build And Test ```bash cargo test --manifest-path compiler/Cargo.toml ``` Run the full local release gate: ```bash ./scripts/release-gate.sh ``` Build the compiler binary: ```bash cargo build --manifest-path compiler/Cargo.toml ./compiler/target/debug/glagol --version ``` Create and check a project: ```bash ./compiler/target/debug/glagol new hello SLOVO_STD_PATH="$PWD/lib/std" ./compiler/target/debug/glagol check hello SLOVO_STD_PATH="$PWD/lib/std" ./compiler/target/debug/glagol test hello ``` Build a native executable when Clang is available: ```bash SLOVO_STD_PATH="$PWD/lib/std" ./compiler/target/debug/glagol build hello -o hello/bin ``` ## 1.0.0-beta.1 Tooling Additions The `1.0.0-beta.1` release improves the common local development and install loop without adding new source-language syntax. Build and execute in one step: ```bash SLOVO_STD_PATH="$PWD/lib/std" ./compiler/target/debug/glagol run hello SLOVO_STD_PATH="$PWD/lib/std" ./compiler/target/debug/glagol clean hello ``` Create alternate project shapes: ```bash ./compiler/target/debug/glagol new numbers --template library ./compiler/target/debug/glagol new workspace-demo --template workspace ``` Install the current checkout: ```bash PREFIX="$HOME/.local" ./scripts/install.sh ``` The installed layout is: ```text /bin/glagol /share/slovo/std/*.slo /share/slovo/runtime/runtime.c ``` Installed `glagol` discovers `share/slovo/std` and `share/slovo/runtime/runtime.c` relative to its executable. `SLOVO_STD_PATH` can still override standard-library search, `SLOVO_RUNTIME_C` or `GLAGOL_RUNTIME_C` can override the runtime C input, and `GLAGOL_CLANG` can select the Clang-compatible compiler. ## 1.0.0-beta.2 Runtime Resource Foundation The `1.0.0-beta.2` release adds beta-scoped runtime/resource foundation work: - `std.fs.open_text_read_result` - `std.fs.read_open_text_result` - `std.fs.close_result` - `std.fs.exists` - `std.fs.is_file` - `std.fs.is_dir` - `std.fs.remove_file_result` - `std.fs.create_dir_result` - matching explicit `lib/std/fs.slo` facades These APIs use beta-scoped opaque `i32` file handles. They do not claim stable file descriptors, writable streams, binary IO, directory handles, sockets, async IO, platform error codes, or stable handle ABI/layout. Directory creation is intentionally narrow and does not imply directory enumeration or recursive filesystem APIs. ## 1.0.0-beta.3 Standard Library Stabilization The `1.0.0-beta.3` release starts the standard-library stabilization slice. It adds a generated standard-library API catalog and `examples/projects/stdlib-composition`, a checked/tested/run-capable program that composes `std.fs`, `std.string`, `std.math`, and `std.io`. ## 1.0.0-beta.4 Language Usability Diagnostics The `1.0.0-beta.4` release improves diagnostics without changing the source language surface. Project/workspace build and run entry failures now use entry-specific diagnostic codes, and non-exhaustive `match` diagnostics have clearer wording with deterministic found-arm output. ## 1.0.0-beta.5 Package And Workspace Discipline The `1.0.0-beta.5` release tightens local package/workspace behavior. Local workspaces may declare `[workspace] default_package = "name"` to select the build/run entry package when multiple packages have entry modules. Duplicate normalized workspace members and missing default-package references are now dedicated diagnostics. `glagol doc -o ` includes a workspace package/dependency summary, new workspace templates declare `default_package = "app"`, and `docs/language/PACKAGES.md` documents the beta local-package rules. Remote registries, lockfiles, semantic-version solving, package publishing, and stable package ABI/layout remain deferred. ## 1.0.0-beta.6 Networking Foundation The `1.0.0-beta.6` release adds a narrow blocking loopback TCP foundation: - compiler-known `std.net.tcp_*_result` calls for connect, listen, bound-port lookup, accept, read-all, write-text, and close - `lib/std/net.slo` source facades and explicit std/local example projects - opaque beta-scoped `i32` socket handles with concrete `result` values This is not a general networking stack. DNS, TLS, UDP, non-loopback binding, async IO, HTTP frameworks, rich host-error ADTs, stable socket ABI/layout, and automatic resource ownership remain deferred. ## 1.0.0-beta.7 Serialization And Data Interchange The `1.0.0-beta.7` release adds a narrow JSON text-construction foundation: - compiler-known `std.json.quote_string` for deterministic compact JSON string quoting - `lib/std/json.slo` source helpers for scalar values, fields, small arrays, and small objects - explicit std/local JSON example projects and a `json-quote-loop` benchmark scaffold This is not a complete JSON library. Full parsing, recursive JSON values, maps/sets, streaming encoders, schema validation, Unicode normalization, and a stable data-interchange API freeze remain deferred. ## 1.0.0-beta.8 Concrete Type Alias Foundation The `1.0.0-beta.8` release adds transparent concrete type aliases: ```slo (type JsonText string) ``` Aliases are module-local names for already supported concrete target types. They may appear in local signatures and annotations, but they do not create new runtime representations or stable ABI names. Project imports of functions that use aliases see the resolved concrete target type. Alias exports, imports, re-exports, generic aliases, parameterized aliases, maps/sets, and new compiler-known runtime names remain out of scope. ## 1.0.0-beta.9 Collection Alias Unification And Generic Reservation The `1.0.0-beta.9` release applies beta.8 concrete aliases inside the current source-authored collection/value-family facades. The public helper names and runtime behavior remain concrete: current vectors, options, and results are still concrete families, and the local aliases are erased before lowering. This release also reserves the generic/map/set direction through diagnostics and documentation only. It does not implement executable generics, maps, sets, traits, inference, monomorphization, iterators, stable ABI/layout promises, or a stable standard-library API freeze. ## 1.0.0-beta.10 Developer Experience API Discovery The `1.0.0-beta.10` release upgrades the generated standard-library API catalog from exported helper names to exact exported helper signatures. The renderer verifies that every exported helper has a matching `(fn ...)` form, normalizes module-local concrete aliases from the public signatures, omits non-exported helpers and `(type ...)` aliases, and keeps the catalog generated from `lib/std/*.slo`. It also adds `glagol symbols ` as an editor-facing metadata command. The output is deterministic S-expression text using `slovo.symbols` schema version `1.0.0-beta.10`; it includes module paths, source spans/ranges, imports, exports, aliases, structs, enums, functions, tests, and workspace package labels. This release is tooling, documentation, and API-discovery work. It does not add executable generics, maps, sets, new runtime helpers, new compiler-known runtime names, ABI/layout guarantees, an LSP server, watch mode, or a stable standard-library API freeze. ## 1.0.0-beta.11 Local Package API Documentation The `1.0.0-beta.11` release extends the beta.10 API discovery lane to local package and module documentation. `glagol doc -o ` includes deterministic exported/public API sections for local modules and workspace packages. Those sections list exact exported function signatures, exported struct fields, and exported enum variants with payload types. They omit non-exported functions, structs, enums, tests, and aliases from the public API surface, and they normalize module-local concrete aliases before rendering public types. This remains beta API discovery. It does not freeze the Markdown schema, create a stable stdlib/API compatibility freeze, add LSP/watch behavior, define SARIF or daemon protocols, set diagnostics schema policy, implement executable generics, maps, or sets, add re-exports, globs, or hierarchical modules, or define package registry semantics. ## 1.0.0-beta.12 Concrete Vector Query And Prefix Parity The `1.0.0-beta.12` release is a source-authored stdlib/helper parity update for concrete vectors. It adds `count_of`, `starts_with`, `without_prefix`, `ends_with`, and `without_suffix` to `std.vec_i64`, and adds `count_of` to `std.vec_f64`, matching the already staged concrete helper style. This release does not change the source language, runtime, compiler-known `std.vec.*` names, ABI/layout contract, or performance contract. Generics, maps/sets, iterators, mutable vectors, slice/view APIs, new runtime helper names, stable stdlib API freeze, and broader collection abstractions remain deferred. ## 1.0.0-beta.13 Diagnostic Catalog And Schema Policy The `1.0.0-beta.13` release is a docs/tooling policy update for the existing diagnostic surface. It adds [`docs/language/DIAGNOSTICS.md`](docs/language/DIAGNOSTICS.md) as the beta policy for `slovo.diagnostic` version `1`. The policy documents the S-expression and JSON encodings, required and optional machine fields, severity/source/range/related-span semantics, JSON-line discipline, source-less diagnostics, artifact-manifest diagnostic metadata, compatibility and migration classes, and the current code catalog covered by the golden diagnostics contract. This release does not change the source language, runtime, stdlib API, diagnostic output shape, compiler CLI, LSP/watch behavior, SARIF/daemon protocols, stable Markdown schema, or stable `1.0.0` diagnostics freeze. ## 1.0.0-beta.14 Benchmark Suite Catalog And Metadata Gate The `1.0.0-beta.14` release documents the existing benchmark suite catalog as beta-scoped metadata tooling. It adds [`benchmarks/README.md`](benchmarks/README.md) with the current ten-suite inventory, local evidence policy, suite-list commands, and exclusions. The root suite catalog commands are: ```bash python3 benchmarks/runner.py --suite-list python3 benchmarks/runner.py --suite-list --json ``` The non-JSON listing is for local review. The JSON listing is beta tooling metadata for local gates and adapters, not a stable public schema. This release does not add benchmark kernels, publish timing numbers, define performance thresholds, change the source language, runtime, stdlib/API surface, diagnostic output, compiler ABI/layout behavior, or make cross-machine performance claims. ## Documentation - [Language Manifest](docs/language/MANIFEST.md) - [Language Specification](docs/language/SPEC-v1.md) - [Diagnostics Policy](docs/language/DIAGNOSTICS.md) - [Local Package And Workspace Guide](docs/language/PACKAGES.md) - [Standard Library API Catalog](docs/language/STDLIB_API.md) - [Benchmark Suite Catalog](benchmarks/README.md) - [Compiler Manifest](docs/compiler/GLAGOL_COMPILER_MANIFEST.md) - [Post-Beta Roadmap](docs/POST_BETA_ROADMAP.md) - [Slovo Whitepaper](docs/papers/SLOVO_WHITEPAPER.md) - [Glagol Whitepaper](docs/papers/GLAGOL_WHITEPAPER.md) Generated PDFs live beside their Markdown sources in `docs/papers/`.
