Installer / x07up

X07’s canonical installer is x07up (toolchain manager).

The bootstrap script (install.sh) installs x07up, then x07up installs the selected toolchain and sets up ~/.x07/bin/ shims. After bootstrap, x07up reads the per-channel bundle manifest (/install/channels/<channel>.json) to resolve compatible component versions. On Windows, run the bootstrap inside WSL2.

Quickstart: see Install.

Prerequisites​

  • macOS / Linux: sh, tar, and either curl or wget (plus a sha256 tool: sha256sum, shasum, or openssl)
  • For compiling/running X07 programs: a C toolchain (x07up doctor --json reports missing deps)
  • Linux: libcurl development headers for packages that link libcurl (for example ext-curl-c)

One-command install​

macOS / Linux:

curl -fsSL https://x07lang.org/install.sh | sh -s -- --yes --channel stable

Then (in the same shell session):

export PATH="$HOME/.x07/bin:$PATH"

Windows (WSL2):

X07 does not currently publish native Windows toolchains. Install and run X07 inside WSL2 (Ubuntu recommended) and use the macOS / Linux installer command above.

CI / agent mode (deterministic + machine-clean)​

In CI, avoid modifying shell profiles and emit a single JSON report:

curl -fsSL https://x07lang.org/install.sh | sh -s -- \
  --yes \
  --channel stable \
  --no-modify-path \
  --json

Toolchain selection (deterministic precedence)​

x07up selects the active toolchain in this order:

  1. X07UP_TOOLCHAIN environment variable
  2. x07-toolchain.toml found by walking up directories
  3. global default from ~/.x07/config.json
  4. fallback: stable (but x07up never auto-installs; you must run x07up install)

Component management​

Use x07up to install/update runtime components that must track the active core release bundle:

x07up component add wasm
x07up component add device-host
x07up component update
x07up component list

x07up component update reads the bundle published for the active installed toolchain tag, so component upgrades stay on the compatibility line blessed by that core release.

Pinning per project​

Write x07-toolchain.toml:

x07up override set v0.1.78

This writes a file like:

[toolchain]
channel = "v0.1.78"
components = ["docs", "skills"]

Notes:

  • channel can be stable or a specific tag like v0.1.78.
  • components controls whether x07up installs the offline docs and skills pack.

Remove it:

x07up override unset

Agent kit (offline docs + skills + project rails)​

  • Offline docs path: x07up docs path --json
  • Skills install:
    • user-scoped: x07up skills install --user
    • project-scoped: x07up skills install --project .
  • Canonical project start (creates AGENT.md, pins the toolchain, and installs project-scoped skills): x07 init

If you’re stuck​

Run:

x07up doctor --json

It reports missing prerequisites and broken toolchain layout in a machine-readable way.
