README.md

Vyi

A small systems language: value semantics, typed absence, parkable compile-time evaluation. Compiles to WebAssembly and native linux. Early alpha.

Install

Prebuilt linux/amd64 and linux/arm64 binaries (plus the standard library) are published by CI. Install with:

curl -fsSL https://forgejo.roberthurst.ca/robert/Vyi/raw/branch/master/scripts/install.sh | bash
# remove later:
# curl -fsSL …/install.sh | bash -s -- --uninstall

That installs into ~/.local by default:

Path Contents
~/.local/bin/vyi compiler CLI
~/.local/bin/vyi-language-server LSP server
~/.local/share/vyi/ standard library ($PREFIX/share/vyi)

Ensure ~/.local/bin is on your PATH. Pin a release with VYI_VERSION=v0.1.0 (once tagged), or a custom prefix with PREFIX=/usr/local.

Artifacts live in the Forgejo generic package registry:

https://forgejo.roberthurst.ca/api/packages/robert/generic/vyi/<version>/
  vyi-linux-amd64
  vyi-linux-arm64
  vyi-language-server-linux-amd64
  vyi-language-server-linux-arm64
  vyi-stdlib.tar.gz

<version> is latest for builds from master, or a tag name such as v0.1.0.

Build from source

cd bootstrap-compiler
go build -o vyi ./cmd/vyi
./vyi run --packages ../packages path/to/main.vyi

Language server:

cd bootstrap-language-server
go build -o vyi-language-server .

Verification gate (from bootstrap-compiler/):

go build ./... && go test ./... -count=1
go test ./transform/ -run Test_Transform_E2E_Native -count=1
