Install forai

The forai CLI is published as `fai` and `forai`. Use the nightly installer for Linux or Apple Silicon macOS, or build from the local source tree.

Downloads the latest nightly release from `forailang/forai`, verifies the checksum when published, and installs `fai` into `~/.local/bin` by default.

curl -fsSL https://raw.githubusercontent.com/forailang/forai/main/install.sh | sh

Create or enter a forai project, then run the normal gates.

fai check
fai test
fai build

The compiler is a Rust workspace. Building from source is useful when iterating on the language or testing local changes.

git clone https://github.com/forailang/forai.git
cd forai
cargo install --path .

Nightly archives are named by OS and architecture. The installer supports Linux x86_64, Linux aarch64, and Apple Silicon macOS.

Override the destination with `INSTALL_DIR=/path/to/bin` or install a different release tag with `FAI_TAG=`.
