Tower Lsp Versions Save

Changed

• Increase lsp-types semantic version range to >=0.79, <0.81. This is safe because the upstream changes only concern proposed LSP features, which this library does not currently support.

Changed

• Improve std::fmt::Debug implementation for Client (PR #216).
• Several API documentation improvements.

Fixed

• Fix infinite loop upon encountering invalid UTF-8 characters in an incoming message (PR #215).

Changed

• Improve log message quality and reduce noise.
• Return responses in corresponding request order to make things easier on the client side (PR #212).
• Change remaining Client notification methods to async fn (PR #213).
• Bump minimum supported Rust version to 1.41.0 (PR #213).

Fixed

• Report missing params as "invalid params" instead of "parse error" (PR #211).

Fixed

• Reject multiple initialize requests sent in quick succession (PR #208).
• Fix bug deserializing jsonrpc field from serde_json::Value (PR #209).

Added

• Add private subcrate tower-lsp-macros for internal use only (PR #202).
• Implement cancellation support via $/cancelRequest (PR #202).
• Officially support serving over TCP (PR #198).

Changed

• Update lsp-types crate from 0.74 to 0.79.
• Have language servers store Client directly as struct field (PR #199).
• Replace jsonrpc-core with minimal JSON-RPC implementation (PR #202).
• Redefine LspService as Service<Incoming, Response = Option<Outgoing>>.
• Implement FusedStream for MessageStream.

Fixed

• Fix typo which caused workspace/didChangeConfiguration to break (PR #195).
• Implement proper parse error recovery in LSP codec (PR #201).
• Refuse to accept further requests after shutdown has been called once.

Removed

• Remove dependency on jsonrpc-core, as tower-lsp no longer relies on it.
• Remove LspService::with_handler() constructor (PR #202).

Changed

• Update lsp-types crate from 0.73 to 0.74 (PR #178). This introduces breaking changes to the following LanguageServer trait method signatures:
  • hover()
  • signatureHelp()
  • goto_declaration()
  • goto_definition()
  • goto_type_definition()
  • goto_implementation()
  • document_highlight()
• Make LanguageServer::initialize() handler async fn (PR #182).
• Accept stdin and stdout handles that are not Send + 'static. This permits the use of std::io::Cursor or Vec<u8> as mock stdio sources for tests, and passing in &mut handles is now supported as well (PR #184).

Fixed

• Fix broken bidirectional request/response routing (PR #184). The original implementation introduced in version 0.9.0 would deadlock under certain conditions.

Changed

• Implement Clone for Client so it can be safely passed to functions expecting 'static values.
• Mark MessageStream as #[must_use].

Added

• Implement support for the following client-to-server messages:
  • textDocument/willSaveWaitUntil
  • textDocument/selectionRange
• Re-export useful jsonrpc-core types in a new jsonrpc module (PR #169).

Changed

• Update lsp-types crate from 0.70 to 0.73 (PR #162).

Fixed

• Fix JSON-RPC delegate for textDocument/foldingRange (PR #167).

Added

• Implement support for the following client-to-server messages:
  • textDocument/documentColor
  • textDocument/colorPresentation
  • textDocument/rangeFormatting
  • textDocument/onTypeFormatting
  • textDocument/foldingRange

Changed

• Server will accept the initialize request from the client only once and will respond with JSON-RPC error code -32600 if sent again (PR #160).

Fixed

• Fix broken links and improve documentation (PRs #152 #157 #158).

Added

• Add info!() message when server initializes to be consistent with the existing info!() message that is emitted when the server exits.
• Implement support for the following client-to-server messages:
  • textDocument/references
  • textDocument/documentLink
  • documentLink/resolve
  • textDocument/rename
  • textDocument/prepareRename
• Implement support for the following server-to-client messages:
  • window/showMessageRequest
  • workspace/workspaceFolders
  • workspace/configuration

Changed

• Improve LSP message encoding efficiency (PR #126).
• Reduce chattiness of trace!() logs (PR #130).
• Change all notification trait methods to async fn (PR #131).
• Implement proper server-to-client request routing (PRs #134 #135).
• Rename Printer to Client.
• Change Client::apply_edit() to return Result<ApplyWorkspaceEditResponse>.
• Change Client::register_capability() to return Result<()>.
• Change Client::unregister_capability() to return Result<()>.

Removed

• Remove redundant serialization steps from Client (PR #129).
