From e3a23dbe7b88d248fc78733812e7d4f50b4cd7ea Mon Sep 17 00:00:00 2001 From: Copilot <198982749+Copilot@users.noreply.github.com> Date: Sat, 20 Sep 2025 23:01:46 +0530 Subject: [PATCH] Add support for setting include paths via initializationParams (#91) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This PR adds the ability to configure include paths dynamically through LSP `initializationParams`, addressing a key limitation for Neovim users where command-line arguments must be static but initialization options can be set dynamically. ## Problem Neovim's LSP configuration requires `cmd` and `args` to be static, making it impossible to dynamically configure include paths based on project context. While Neovim supports changing `initializationParams` via the `before_init` callback, protols didn't support include path configuration through this mechanism. ## Solution Extended the LSP initialization process to parse and use include paths from `initializationParams.include_paths`. The implementation: - **Integrates seamlessly**: Merges with existing CLI and configuration file include paths - **Handles errors gracefully**: Invalid formats are logged but don't crash the server - **Maintains compatibility**: All existing functionality continues to work unchanged ## Usage Neovim users can now configure include paths dynamically: ```lua require'lspconfig'.protols.setup{ before_init = function(_, config) config.init_options = { include_paths = { "/usr/local/include/protobuf", "vendor/protos", "../shared-protos" } } end } ``` ## Implementation Details - Extended `WorkspaceProtoConfigs` to store initialization include paths - Added `parse_init_include_paths()` function to handle JSON parsing with robust error handling - Updated include path resolution to merge all sources (config file + CLI + initialization) - Added comprehensive test coverage with 6 new test cases - Updated documentation with usage examples ## Testing All existing tests continue to pass, plus new tests covering: - Array format parsing - String format parsing - Invalid format handling - Integration with existing include path sources - Real-world usage scenarios Fixes #90. --- 💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers.
