        "path": "/path/to/slint-lsp",

Development

The extension will download the version of the Slint LSP binary match the version of the extension. To test out the development version of the extension, start zed with the SLINT_DEV_MODE environment variable set, and "Install Dev Extension" from the editors/zed folder, or "rebuild extension". When the SLINT_DEV_MODE environment variable is set, the extension will download the latest nightly version of the LSP binary.
