Alloy is a formal specification language for describing structures and a tool for exploring them.

You may also need to configure the filetype for Alloy (*.als) files:

```
autocmd BufNewFile,BufRead *.als set filetype=alloy
```

or

```lua
vim.filetype.add({
  pattern = {
    ['.*/*.als'] = 'alloy',
  },
})
```

Alternatively, you may use a syntax plugin like https://github.com/runoshun/vim-alloy.
