# Demos

Three Golo programs to open in Turbo Golo. Each runs under `golo`, and the tests pass under `golo --test`:

| Directory | What it shows | Run it |
| --- | --- | --- |
| `hello/` | The smallest program: a module, a function, a greeting | `golo demos/hello/hello.golo` |
| `shapes/` | Structs, a union with two variants, augmentations, closures and a comprehension — with a `*_test.golo` beside it | `golo demos/shapes/shapes.golo` then `golo --test demos/shapes` |
| `syntax-tour/` | One of everything the scanner colours, each line of `tour.golo` running; `lexer-only.golo` beside it holds the tokens the lexer reads and the parser refuses, coloured but not runnable | `golo demos/syntax-tour/tour.golo` |

From the repository root:

```bash
turbo-golo demos/shapes/shapes.golo
```

Open one, press `F9` for the project tree, and `Alt-G` for the Golo menu. Create the project's tools file from that menu and **Run** asks which script to run.
