Install and download

Install the Faber CLI from the current prebuilt release. The compiler front end ships inside the faber binary; you do not need a separate Radix install for ordinary package work.

This page covers the current release only. For any other version — with its own pinned download and full release notes — see Releases.

Current release#

Prebuilt archives#

The archives ship a bin/ and a share/ tree. Install both so the reader packs resolve beside the binary (the checksum files may name the original build path, so verify by comparing the first hash field against the local archive instead of relying on sha256sum -c path matching).

macOS arm64#

curl -fsSL -o faber.tgz \
  https://github.com/faberlang/releases/releases/download/faber-v1.6.0/faber-v1.6.0-aarch64-apple-darwin.tar.gz
curl -fsSL -o faber.tgz.sha256 \
  https://github.com/faberlang/releases/releases/download/faber-v1.6.0/faber-v1.6.0-aarch64-apple-darwin.tar.gz.sha256
expected=$(awk '{print $1}' faber.tgz.sha256)
actual=$(shasum -a 256 faber.tgz | awk '{print $1}')
test "$actual" = "$expected"
tar -xzf faber.tgz
# The archive ships bin/ and share/; keep them together so the reader packs
# resolve beside the binary.
sudo mv bin/faber /usr/local/bin/faber
sudo mv share/faber /usr/local/share/faber
faber --version

Linux x64#

curl -fsSL -o faber.tgz \
  https://github.com/faberlang/releases/releases/download/faber-v1.6.0/faber-v1.6.0-x86_64-unknown-linux-gnu.tar.gz
curl -fsSL -o faber.tgz.sha256 \
  https://github.com/faberlang/releases/releases/download/faber-v1.6.0/faber-v1.6.0-x86_64-unknown-linux-gnu.tar.gz.sha256
expected=$(awk '{print $1}' faber.tgz.sha256)
actual=$(sha256sum faber.tgz | awk '{print $1}')
test "$actual" = "$expected"
tar -xzf faber.tgz
sudo mv bin/faber /usr/local/bin/faber
sudo mv share/faber /usr/local/share/faber
faber --version

You should see a version line for the CLI and a diagnostic explanation. If faber is not found, check that the directory containing the binary is on PATH.

First package check#

With the CLI on PATH, clone the public examples (or any Faber package) and type-check. Product packages resolve dependencies from the Cista store through faber.lock; local source checkouts are only for explicit library-development overrides.

git clone https://github.com/faberlang/examples.git
faber check examples/ai-workbench/packages/faber-ai
