Install the toolchain

Lux ships as a small set of native binaries built from the workspace. There is no package manager to configure and nothing to download at runtime.

Build the binaries

# From the joulesperbit workspace — builds the `lux` binary:
cargo build --release -p lux-cli

# The canonical formatter is a separate binary:
cargo build --release -p lux-fmt

Put them on your PATH

export PATH="$PWD/target/release:$PATH"

Verify

lux version
# → Lux v0.1.0

Optional: editor support

Build the language server for diagnostics, completion, hover docs, and go-to-definition in your editor:

cargo build --release -p lux-lsp

Point your editor’s Lux extension at the lux-lsp binary and reload.

What you get

Binary	Role
`lux`	run · new · check · build · test · dev · repl · lift · audit · serve
`lux-fmt`	the canonical formatter — format in place, `--check`, `--stdin`, recursive
`lux-lsp`	language server for editor integration

Formatting is deliberately not a lux fmt subcommand — lux-fmt is its own binary with one canonical style and no configuration.

Next: build a reactive app, or skip straight to the playground — it needs no install at all.
