From 060d5efb9b26870774bc747581dc05587430ad02 Mon Sep 17 00:00:00 2001 From: Ram Nadella Date: Sun, 29 Jun 2025 23:00:37 -0400 Subject: [PATCH 1/2] feat: add LSP progress reporting for workspace indexing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements work done progress notifications during initial workspace indexing: - Check client capabilities for work done progress support - Send progress notifications showing file discovery and indexing status - Display "Indexing file X of Y" with percentage during parallel processing - Gracefully fall back to silent indexing if client doesn't support progress - Thread-safe progress reporting across parallel file processing This provides visual feedback in VSCode and other LSP clients that support work done progress, improving user experience during large workspace indexing. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- pylight/src/index/symbol_index.rs | 135 +++++++++++++++++++++ pylight/src/lsp/mod.rs | 1 + pylight/src/lsp/progress.rs | 187 ++++++++++++++++++++++++++++++ pylight/src/lsp/server.rs | 81 ++++++++++++- 4 files changed, 399 insertions(+), 5 deletions(-) create mode 100644 pylight/src/lsp/progress.rs diff --git a/pylight/src/index/symbol_index.rs b/pylight/src/index/symbol_index.rs index cc37a54..fa587a8 100644 --- a/pylight/src/index/symbol_index.rs +++ b/pylight/src/index/symbol_index.rs @@ -227,6 +227,89 @@ impl SymbolIndex { Ok(()) } + /// Parse and index a list of Python files in parallel with progress tracking + /// Returns (number of files parsed, total symbols, elapsed time) + pub fn parse_and_index_files_with_progress( + self: Arc, + python_files: Vec, + progress_callback: F, + ) -> Result<(usize, usize, std::time::Duration)> + where + F: Fn(usize, usize) + Send + Sync, + { + let start_time = std::time::Instant::now();
