You can find some examples by looking at the standard library [implementation](https://github.com/ascandone/kestrel_core/tree/main/src)\n\n### Get started\n\n\u003e You can try kestrel without installing it on the [online playground](https://kestrel-playground.vercel.app/).\n\nInstall the `kestrel` cli using npm:\n\n```bash\nnpm install -g kestrel-lang\n```\n\nLsp integration is available as a [vscode extension](https://marketplace.visualstudio.com/items?itemName=ascandone.kestrel-vscode).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fascandone%2Fkestrel-lang","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fascandone%2Fkestrel-lang","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fascandone%2Fkestrel-lang/lists"}
