Might investigate into doing some caching later down the line. * Integrate document store and notifications Add the document store to the Server struct. Also separate the handlers into request and notifications as their data structure and expected response differ. * Separate values assignment to different files In order to remove the need to modify `initialize.zig` and `protocol.zig` whenever a new version or new server capabilities is implemented, version was moved to the Server struct and capabilities to a separate file. * Add support for incremental change Document store now supports incremental change of files which mean it's possible to change a part of the file without inserting the whole file each time. * Add notification for didOpen and didChange Currently just stores opened buffer into a StringHashMap which will allow parsing them later on. * Fix enum conversion The text document sync type was being sent as a string instead of its integer equivalent. * Add tests for document store * Ensure test wiring * Add more documentation to README.md --------- Co-authored-by: Anton-4 <17049058+Anton-4@users.noreply.github.com> --- src/lsp/README.md | 37 +++++++-- src/lsp/capabilities.zig | 28 +++++++ src/lsp/document_store.zig | 108 +++++++++++++++++++++++++++ src/lsp/handlers/did_change.zig | 95 +++++++++++++++++++++++ src/lsp/handlers/did_open.zig | 43 +++++++++++ src/lsp/handlers/initialize.zig | 5 +- src/lsp/mod.zig | 1 + src/lsp/protocol.zig | 4 +- src/lsp/server.zig | 30 +++++++- src/lsp/test.zig | 1 + src/lsp/test/document_store_test.zig | 31 ++++++++ src/lsp/test/server_test.zig | 36 +++++++++ 12 files changed, 407 insertions(+), 12 deletions(-) create mode 100644 src/lsp/capabilities.zig create mode 100644 src/lsp/document_store.zig create mode 100644 src/lsp/handlers/did_change.zig create mode 100644 src/lsp/handlers/did_open.zig create mode 100644 src/lsp/test/document_store_test.zig diff --git a/src/lsp/README.md b/src/lsp/README.md index dec0382ad9..6efe38db76 100644 --- a/src/lsp/README.md +++ b/src/lsp/README.md @@ -4,14 +4,24 @@ written in Zig as part of the Rust to Zig rewrite. ## Current state The experimental LSP currently only holds the scaffolding for the incoming implementation. -It doesn't implement any LSP capabilities yet except `initialized` and `exit` which allows it -to be connected to an editor and verify it's actually running. +It doesn't provide any features yet, but it does connect to your editor, detect file change +and store the buffer in memory. +The following request have been handled : +- `initialize` +- `shutdown` +The following notifications have been handled : +- `initialized` +- `exit` +- `didOpen` (stores the buffer into a `StringHashMap`, but doesn't do any action on it) +- `didChange` (same as `didOpen`, but also supports incremental changes) + ## How to implement new LSP capabilities The core functionalities of the LSP have been implemented in a way so that `transport.zig` and `protocol.zig` shouldn't have to be modified as more capabilities are added.
