GoloScript
GoloScript is a Golo language interpreter implemented in Go. This project reproduces the main features of the original Golo language (https://github.com/eclipse-archived/golo-lang) which was developed in Java for the JVM by Julien Ponge.
Description
Golo is a dynamic and weakly typed programming language designed to be simple and expressive. This interpreter implements the core language features using Go.

Hello World
module hello.World
function main = |args| {
println("Hello, GoloScript! 👋")
}
Installation
- You can download the precompiled binaries from the Releases page.
- After downloading, make the binary executable:
# On Linux/macOS
chmod +x golo-script-<version>-<platform>
For example:
chmod +x ./golo-v0.0.3-darwin-arm64
# Then run:
./golo-v0.0.3-darwin-arm64 --version
./golo-v0.0.3-darwin-arm64 --about
./golo-v0.0.3-darwin-arm64 --help
On MacOS, you might need to allow the app to run in System Preferences > Security & Privacy.
Installation to system path
You can move the binary to a directory in your system PATH for easier access:
# Example for Linux/macOS
sudo mv golo-v0.0.3-darwin-arm64 /usr/local/bin/golo
Use it like a bash script
You can use GoloScript to run Golo scripts directly from the command line, similar to how you would use bash or python interpreters.
# Make your Golo script executable
chmod +x your_script.golo
# Add the shebang line at the top of your_script.golo
#!/usr/bin/env golo
# Now you can run your Golo script directly
./your_script.golo
Example:
#!/usr/bin/env golo
import gololang.AnsiCodes
function hello = |name| -> "👋 Hello, " + name + "!🤗"
# Green text
fg_green()
print(hello("Bob Morane"))
reset()
println()
GoloScript Playground
You can explore and run GoloScript in the Golo Playground.
# git clone this repository:
git clone https://codeberg.org/TypeUnsafe/golo-playground.git
# start the Golo Playground
cd golo-playground
docker compose up -d
docker compose exec golo-playground bash
# run a Golo Script
cd 01-hello-world
golo hello.golo
🐳 GoloScript Docker Image
docker pull k33g/gololang:v0.0.3
cat > hello.golo << 'EOF'
module hello.Docker
function main = |args| {
println("Hello from GoloScript in Docker! 🐳")
}
EOF
docker run --rm -v $(pwd):/app -w /app k33g/gololang:v0.0.3 /golo ./hello.golo
We have VSCode grammar support!
It’s not published yet, but you can find it in this repository.
Look at the VSCode Extension Installation Instructions to add Golo syntax highlighting to your VSCode editor.
