handl-lang

Set up the platform ​

This guide gets the published platform repos building on your machine.

Requirements ​

  • A recent stable Rust toolchain (1.80 or newer) and cargo.
  • git.

Clone and build ​

Clone the platform workspace and the kernel as siblings — host's [patch] table resolves kernel crates from ../kernel:

sh
git clone https://github.com/handl-lang/host
git clone https://github.com/handl-lang/kernel

cd host
cargo check --workspace
cargo test --workspace

Clone the engines and language data only as you need them:

sh
git clone https://github.com/handl-lang/engine-exec
git clone https://github.com/handl-lang/engine-exec-tree-walk
git clone https://github.com/handl-lang/engine-lex
git clone https://github.com/handl-lang/engine-parse
git clone https://github.com/handl-lang/engine-transform
git clone https://github.com/handl-lang/kit-prelude-lang

For a downstream crate ​

Depend on the platform directly — no checkout needed:

toml
[dependencies]
handl-platform = { git = "https://github.com/handl-lang/host" }
serde_json = "1"

What is not here ​

The hnl CLI, editor extensions, toolchain engines, curated kits, and standard library are not yet released — there is nothing to install.
