|
|
||
| A lightweight Go+ language server for [spx](https://github.com/goplus/spx) that runs in the browser using WebAssembly. | ||

||
| ## LSP methods | ||
|
|
||
| | Category | Method | Purpose & Explanation | | ||
| |----------|--------|-----------------------| | ||
| | **Lifecycle Management** ||| | ||
| || [`initialize`](https://microsoft.github.io/language-server-protocol/specifications/base/0.9/specification/#initialize) | Performs initial handshake, establishes server capabilities and client configuration. | | ||
| || [`initialized`](https://microsoft.github.io/language-server-protocol/specifications/base/0.9/specification/#initialized) | Marks completion of initialization process, enabling request processing. | | ||
| || [`shutdown`](https://microsoft.github.io/language-server-protocol/specifications/base/0.9/specification/#shutdown) | *Protocol conformance only.* | | ||
| || [`exit`](https://microsoft.github.io/language-server-protocol/specifications/base/0.9/specification/#exit) | *Protocol conformance only.* | | ||
| | **Document Synchronization** ||| | ||
| || [`textDocument/didOpen`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#textDocument_didOpen) | Registers new document in server state and triggers initial diagnostics. | | ||
| || [`textDocument/didChange`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#textDocument_didChange) | Synchronizes document content changes between client and server. | | ||
| || [`textDocument/didSave`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#textDocument_didSave) | Processes document save events and triggers related operations. | | ||
| || [`textDocument/didClose`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#textDocument_didClose) | Removes document from server state and cleans up resources. | | ||

| | **Symbols & Navigation** ||| | ||
| || [`textDocument/definition`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#textDocument_definition) | Locates symbol definitions across workspace. | | ||
| || [`textDocument/declaration`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#textDocument_declaration) | Finds symbol declarations. | | ||
| || [`textDocument/typeDefinition`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#textDocument_typeDefinition) | Navigates to type definitions of variables/fields. | | ||
| || [`textDocument/implementation`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#textDocument_implementation) | Locates implementations. | | ||
| || [`textDocument/references`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#textDocument_references) | Finds all references of a symbol. | | ||
| || [`textDocument/documentSymbol`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#textDocument_documentSymbol) | Provides document symbols for outline/navigation. | | ||
| || [`textDocument/documentHighlight`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#textDocument_documentHighlight) | Highlights other occurrences of selected symbol. | | ||
| || [`workspace/symbol`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#workspace_symbol) | Provides workspace-wide symbol search with name matching patterns. | | ||
| || [`workspaceSymbol/resolve`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#workspace_symbolResolve) | Provides detailed information for selected workspace symbols. | | ||
| | **Code Quality** ||| | ||
| || [`textDocument/publishDiagnostics`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#textDocument_publishDiagnostics) | Reports code errors and warnings in real-time. | | ||

|
|
||
| ## Predefined commands | ||
|
|
||
| ### Resource renaming | ||
|
|
||
| The `spx.renameResources` command enables renaming of resources referenced by string literals (e.g., `play "explosion"`) | ||
| across the workspace. | ||
|
|
||
| *Request:* | ||
|
|
||
| - method: [`workspace/executeCommand`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#workspace_executeCommand) | ||
| - params: [`ExecuteCommandParams`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#executeCommandParams) | ||
| defined as follows: | ||
|
|
||
| ```typescript | ||
| interface ExecuteCommandParams { | ||
| /** | ||
| * The identifier of the actual command handler. | ||
| */ | ||
| command: 'spx.renameResources' | ||
|
|
||
| /** | ||
| * Arguments that the command should be invoked with. | ||
| */ | ||
| arguments: RenameResourceParams[] | ||
| } | ||
| ``` | ||
|
|
||
| ```typescript | ||
| /** | ||
| * Parameters to rename a resource in the workspace. | ||
| */ | ||
| interface RenameResourceParams { | ||
| /** | ||
| * The resource. | ||
| */ | ||
| resource: ResourceIdentifier | ||
|
|
||
| /** | ||
| * The new name of the resource. | ||
| */ | ||
| newName: string | ||
| } | ||
| ``` | ||
|
|
||
| ```typescript | ||
| interface ResourceIdentifier { | ||
| /** | ||
| * The resource's URI. | ||
| */ | ||
| uri: URI | ||
| } | ||
| ``` | ||
|
|
||
| *Response:* | ||
|
|
||
| - result: [`WorkspaceEdit`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#workspaceEdit) | ||
| | `null` describing the modification to the workspace. `null` should be treated the same as [`WorkspaceEdit`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#workspaceEdit) | ||
| with no changes (no change was required). | ||
| - error: code and message set in case when rename could not be performed for any reason. |
