+ "markdownDescription": "Enables automatic discovery of projects using [`DiscoverWorkspaceConfig::command`].\n\n[`DiscoverWorkspaceConfig`] also requires setting `progress_label` and `files_to_watch`.\n`progress_label` is used for the title in progress indicators, whereas `files_to_watch`\nis used to determine which build system-specific files should be watched in order to\nreload rust-analyzer.\n\nBelow is an example of a valid configuration:\n```json\n\"rust-analyzer.workspace.discoverConfig\": {\n \"command\": [\n \"rust-project\",\n \"develop-json\"\n ],\n \"progressLabel\": \"rust-analyzer\",\n \"filesToWatch\": [\n \"BUCK\"\n ]\n}\n```\n\n## On `DiscoverWorkspaceConfig::command`\n\n**Warning**: This format is provisional and subject to change.\n\n[`DiscoverWorkspaceConfig::command`] *must* return a JSON object corresponding to\n`DiscoverProjectData::Finished`:\n\n```norun\n#[derive(Debug, Clone, Deserialize, Serialize)]\n#[serde(tag = \"kind\")]\n#[serde(rename_all = \"snake_case\")]\nenum DiscoverProjectData {\n Finished { buildfile: Utf8PathBuf, project: ProjectJsonData },\n Error { error: String, source: Option<String> },\n Progress { message: String },\n}\n```\n\nAs JSON, `DiscoverProjectData::Finished` is:\n\n```json\n{\n // the internally-tagged representation of the enum.\n \"kind\": \"finished\",\n // the file used by a non-Cargo build system to define\n // a package or target.\n \"buildfile\": \"rust-analyzer/BUILD\",\n // the contents of a rust-project.json, elided for brevity\n \"project\": {\n \"sysroot\": \"foo\",\n \"crates\": []\n }\n}\n```\n\nIt is encouraged, but not required, to use the other variants on `DiscoverProjectData`\nto provide a more polished end-user experience.\n\n`DiscoverWorkspaceConfig::command` may *optionally* include an `{arg}`, which will be\nsubstituted with the JSON-serialized form of the following enum:\n\n```norun\n#[derive(PartialEq, Clone, Debug, Serialize)]\n#[serde(rename_all = \"camelCase\")]\npub enum DiscoverArgument {\n Path(AbsPathBuf),\n Buildfile(AbsPathBuf),\n}\n```\n\nThe JSON representation of `DiscoverArgument::Path` is:\n\n```json\n{\n \"path\": \"src/main.rs\"\n}\n```\n\nSimilarly, the JSON representation of `DiscoverArgument::Buildfile` is:\n\n```json\n{\n \"buildfile\": \"BUILD\"\n}\n```\n\n`DiscoverArgument::Path` is used to find and generate a `rust-project.json`, and\ntherefore, a workspace, whereas `DiscoverArgument::buildfile` is used to to update an\nexisting workspace.
