🌀 Inference Programming Language

Inference is a programming language designed for building verifiable software. It is featured with static typing, explicit semantics, and formal verification capabilities available out of the box.

Inference allows for mathematically verifying code correctness without learning provers. Keep the implementation correct, even with vibecode.

Important

The project is in early development. Internal design and implementation are subject to change. So please be patient with us as we build out the language and tools.

Inference Suite CLI (infs)

infs is the unified toolchain CLI for Inference. It provides subcommands for building, managing, and working with Inference projects.

Build Command

The infs build command compiles a single .inf source file through three phases:

1. Parse (--parse) – Build the typed AST using tree-sitter
2. Analyze (--analyze) – Perform type checking and semantic validation (WIP)
3. Codegen (--codegen) – Emit WebAssembly binary with optional Rocq translation

You must specify at least one phase flag; phases run in canonical order (parse → analyze → codegen).

Basic Usage

# Via cargo
cargo run -p infs -- build path/to/file.inf --parse

# After building, call the binary directly
./target/debug/infs build path/to/file.inf --codegen -o

Compilation Modes

The compiler supports two modes that control optimization and verification behavior:

1. compile produces optimized production binaries. Non-deterministic spec nodes are stripped since they have no runtime meaning.
2. proof produces WASM for formal verification. Spec functions (containing non-deterministic operations) are compiled unoptimized to preserve structural correspondence with the source code for Rocq formalization. Execution functions use the target's release optimization so that proofs cover the actual deployed code.

Read more about compilation modes in the book.

Output Flags

• -o – Generate WASM binary file in out/ directory
• -v – Generate Rocq (.v) translation file in out/ directory

Show Version

infs version
infs --version

Exit Codes

Code	Meaning
0	Success
1	Usage / IO / Parse failure

Future Commands (Planned)

• infs install – Download and install toolchain versions
• infs new – Scaffold new projects
• infs doctor – Verify installation health
• infs (no args) – Launch TUI interface

Distribution

Prebuilt binaries are available for each release. Two CLI tools are distributed:

• infs - Full-featured toolchain CLI (recommended for all users)
• infc - Standalone compiler CLI

Release Artifacts

Platform	infs	infc
Linux x64	infs-linux-x64.tar.gz	infc-linux-x64.tar.gz
Windows x64	infs-windows-x64.zip	infc-windows-x64.zip
macOS ARM64	infs-macos-apple-silicon.tar.gz	infc-macos-apple-silicon.tar.gz

Directory Structure

<distribution-folder>/
└── infs (or infc)          # The CLI binary

The CLI binaries are self-contained and require no external dependencies.

Building from Source

To build Inference from source:

For detailed platform-specific setup instructions, see:

• Linux Development Setup
• macOS Development Setup
• Windows Development Setup

Dependencies

No external binaries are required. The compiler generates WebAssembly directly via wasm-encoder.

Build Steps

1. Clone the repository:

   git clone https://github.com/Inferara/inference.git
   cd inference

2. Build the project:

   cargo build --release

The compiled binaries will be in target/release/ (infs and infc).

Build Commands

The workspace is configured for efficient development:

• cargo build - Builds only the core/ crates (faster for core development)
• cargo build-full - Builds the entire workspace, including tools and tests
• cargo test - Runs tests for core/ crates and the tests/ integration suite
• cargo test-full - Runs tests for all workspace members, including tools
