ryegen

Package ryegen allows the use of Go libraries in the Rye programming language (https://ryelang.org/).

It is an automatic binding generation utility that allows the creation of custom Rye interpreters, which include the functionality of specific Go libraries.

Getting started

Create a new Go project

mkdir my_ryegen_project
cd my_ryegen_project
go mod init my_ryegen_project
go get -u github.com/refaktor/ryegen@main
go get -u github.com/refaktor/rye@main

Set up ryegen using ryegen-init (replace "fyne" with a name for your library and "fyne.io/fyne/v2" with any Go package)

go run github.com/refaktor/ryegen/cmd/ryegen-init@main fyne fyne.io/fyne/v2

Run the generator

go mod tidy
go generate ./...
go mod tidy

Edit the "config.toml" file to your liking. See https://github.com/refaktor/rye-fyne/blob/main/generate/config.toml and https://github.com/refaktor/rye-ebitengine/blob/main/generate/config.toml for examples.

Optional: Edit "bindings.txt" to exclude specific functions from your bindings.

Re-run go generate ./... after making any configuration changes.

Build the Rye interpreter with bindings

go build

Adding another binding / managing bindings with build tags

Re-run ryegen-init with another name and package

go run github.com/refaktor/ryegen/cmd/ryegen-init@main ebiten github.com/hajimehoshi/ebiten

Compile the Rye interpreter with bindings

# Bind both libraries
go build
# Build without fyne
go build -tags "b_no_fyne"

You can customize the bindings' build tag names in their respective config.toml files.
