- Updated folding actions and engine for more consistent behavior.
- Added helper function `is_fold_hidden()` to check fold visibility state.
- Improved gutter renderer to handle collapsible code blocks more reliably.
- Refined tag handling for invisible folds to prevent desync issues.
- Removed code fold Fix related entry in `TODO.md`.
- Rename GodotHandler to GDScriptHandler in LSP client
- Fix unload() method naming in nanoesq_temp_buffer plugin
- Return manifest_meta in manifest_manager for manual launch plugins
- Properly destroy tabs_widget, viewport, and scrolled_win on unload
- Refactor plugin removal to search all manifest lists and fix cleanup order
- Fix widget reference in plugins_ui (use child instead of box)
* Rename legacy controller subsystem (LSPController, websocket controller, controller events, and base classes)
into clarified client module for LSP communication
* Structure around LSPManager and LSPManagerClient to handle orchestration and client lifecycle
* Update plugin integration to use LSPManager instead of LSPController
* Simplify architecture by reducing controller indirection
- Remove legacy LSPManager dialog implementation
- Introduce LSPController as the central LSP entry point
- Route UI interactions through lsp_controller.lsp_manager_ui
- Move client lifecycle handling out of ProviderResponseCache
- Simplify completion cache and matcher filtering
- Improve LSP completion item parsing with safer fallbacks
- Modernize typing (Python 3.10 union syntax)
- Remove unused imports and dead code
- Use GLib.idle_add for safe UI scrolling operations
- Minor comment and spelling fixes
- Add `_lsp_java_class_file_contents` request to fetch contents of compiled Java classes via LSP (`java/classFileContents`).
- Handle `java/classFileContents` responses by opening a new buffer with Java syntax highlighting and inserting the returned source.
- Update definition handling to pass URI and range, enabling precise cursor placement after navigation.
- Detect `jdt://` URIs in `textDocument/definition` responses and request class file contents instead of direct navigation.
- Move goto navigation logic into `LSPServerEventsMixin`, using event system to access the active view and position the cursor.
- Expose `emit` and `emit_to` to the response cache for event dispatching.
- Restrict completion activation to `USER_REQUESTED`.
- Add TODO note about mapping language IDs to dedicated response handlers.
- Moved plugins to proper sub groups (autopairs, code_minimap, colorize, commentzar, info_bar, markdown_preview, prettify_json, search_replace, tabs_bar, telescope, toggle_source_view, lsp_client)
- Add filter_out_loaded_files to prevent opening already-loaded files
- Add INDEPENDENT source view state
- Fix cursor scroll position on buffer switch
- Fix signal blocking during file load
- Fix word boundary in completion provider
- Refactor code events into single events module
