Struct AppContext 

pub struct AppContext { /* private fields */ }

Shared application context threaded through all command handlers.

Holds the language provider, backup/checkpoint stores, configuration, and call graph engine. Constructed once at startup and passed by reference to dispatch.

Stores use RefCell for interior mutability — the binary is single-threaded (one request at a time on the stdin read loop) so runtime borrow checking is safe and never contended.

Implementations

impl AppContext

pub fn new(provider: Box<dyn LanguageProvider>, config: Config) -> Self

pub fn provider(&self) -> &dyn LanguageProvider

Access the language provider.

pub fn backup(&self) -> &RefCell<BackupStore>

Access the backup store.

pub fn checkpoint(&self) -> &RefCell<CheckpointStore>

Access the checkpoint store.

pub fn config(&self) -> Ref<'_, Config>

Access the configuration (shared borrow).

pub fn config_mut(&self) -> RefMut<'_, Config>

Access the configuration (mutable borrow).

pub fn callgraph(&self) -> &RefCell<Option<CallGraph>>

Access the call graph engine.

pub fn watcher(&self) -> &RefCell<Option<RecommendedWatcher>>

Access the file watcher handle (kept alive to continue watching).

pub fn watcher_rx(&self) -> &RefCell<Option<Receiver<Result<Event>>>>

Access the watcher event receiver.

pub fn lsp(&self) -> RefMut<'_, LspManager>

Access the LSP manager.

pub fn lsp_notify_file_changed(&self, file_path: &Path, content: &str)

Notify LSP servers that a file was written. Call this after write_format_validate in command handlers.

pub fn lsp_notify_and_collect_diagnostics( &self, file_path: &Path, content: &str, timeout: Duration, ) -> Vec<StoredDiagnostic>

Notify LSP and optionally wait for diagnostics.

Call this after write_format_validate when the request has "diagnostics": true. Sends didChange to the server, waits briefly for publishDiagnostics, and returns any diagnostics for the file. If no server is running, returns empty immediately.

pub fn lsp_post_write( &self, file_path: &Path, content: &str, params: &Value, ) -> Vec<StoredDiagnostic>

Post-write LSP hook: notify server and optionally collect diagnostics.

This is the single call site for all command handlers after write_format_validate. When diagnostics is true, it notifies the server, waits briefly, drains queued LSP notifications, and returns diagnostics for the file. When false, it just notifies (fire-and-forget).
