Install the OntoCore CLI (macOS and Windows)¶

Canonical install: Install. Most users never need this page. The OntoCode VS Code / Cursor extension bundles ontocore-lsp. Install the extension for IDE work and skip compiling the CLI unless you need ontocore for CI, scripting, or local validation outside the editor.

Release CLI tarballs are Linux x64 only (x86_64-unknown-linux-gnu). On macOS and Windows, install from crates.io with Rust. On Linux arm64 (and other non-x64 targets), there is no tarball — use cargo install below or the LSP bundled in the VSIX (platform compatibility).

Canonical pin: 0.26.2 (TAGGED_RELEASE). See also Install CLI & CI (detail) and CI integration (Linux CI prefers the release tarball).

Prerequisites¶

Apple Silicon notes¶

• Install the aarch64 Rust toolchain via rustup on Apple Silicon Macs (default on current macOS).
• Ensure ~/.cargo/bin is on your PATH (rustup installer usually configures this).

Verify tools¶

rustc --version   # 1.88 or newer
cargo --version

macOS:

xcode-select -p   # should print a Developer path

Install¶

cargo install ontocore-cli --locked --version 0.26.2

Confirm:

ontocore --help
which ontocore   # typically ~/.cargo/bin/ontocore

First commands¶

Use your ontology directory (there is no fixtures/ outside a git clone):

ontocore validate /path/to/your/ontologies
ontocore query /path/to/your/ontologies "SELECT * FROM classes"

When to use the extension instead¶

Optional: prebuilt language server (skip cargo install for LSP)¶

Release assets include platform-specific ontocore-lsp binaries (for example ontocore-lsp-*-apple-darwin.tar.gz, ontocore-lsp-*-pc-windows-msvc.zip, Linux gnu/musl and arm64 variants). Download, verify against SHA256SUMS, extract, and point ontocode.lspPath at the binary. Most users should keep the bundled LSP from the VSIX and skip this.
