# 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.2`.

## 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.2` keeps the `1.0.0-beta` language baseline, includes the
`1.0.0-beta.1` tooling/install hardening slice, and adds the first
runtime/resource foundation bundle. The language baseline supports practical
local command-line programs and libraries with:

- modules, explicit imports, packages, and local workspaces
- `new`, `check`, `fmt`, `test`, `doc`, and `build`
- `i32`, `i64`, `u32`, `u64`, `f64`, `bool`, `string`, and internal `unit`
- structs, enums, fixed arrays, concrete vectors, option/result families, and
  current `match`
- explicit `std/*.slo` imports from `lib/std`, installed `share/slovo/std`, or
  `SLOVO_STD_PATH`
- hosted native builds through LLVM IR, Clang, and `runtime/runtime.c`

Still deferred before stable: generics, maps/sets, broad package registry
semantics, networking/async, LSP/watch/debug-adapter guarantees, stable ABI and
layout, and a stable standard-library compatibility freeze.

## 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
<prefix>/bin/glagol
<prefix>/share/slovo/std/*.slo
<prefix>/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.
