LspServer

class LspServer()

Provides Language Server Protocol functionality for code intelligence to provide IDE-like features such as code completion, symbol search, and more.

Attributes:

  • language_id LspLanguageId - The language server type (e.g., “python”, “typescript”).
  • path_to_project str - Absolute path to the project root directory.
  • instance SandboxInstance - The Sandbox instance this server belongs to.

LspServer.__init__

def __init__(language_id: LspLanguageId, path_to_project: str,
toolbox_api: ToolboxApi, instance: SandboxInstance)

Initializes a new LSP server instance.

Arguments:

  • language_id LspLanguageId - The language server type (e.g., LspLanguageId.TYPESCRIPT).
  • path_to_project str - Absolute path to the project root directory.
  • toolbox_api ToolboxApi - API client for Sandbox operations.
  • instance SandboxInstance - The Sandbox instance this server belongs to.

LspServer.start

@intercept_errors(message_prefix="Failed to start LSP server: ")
def start() -> None

Starts the language server.

This method must be called before using any other LSP functionality. It initializes the language server for the specified language and project.

Example:

lsp = sandbox.create_lsp_server("typescript", "/workspace/project")
lsp.start() # Initialize the server
# Now ready for LSP operations

LspServer.stop

@intercept_errors(message_prefix="Failed to stop LSP server: ")
def stop() -> None

Stops the language server.

This method should be called when the LSP server is no longer needed to free up system resources.

Example:

# When done with LSP features
lsp.stop() # Clean up resources

LspServer.did_open

@intercept_errors(message_prefix="Failed to open file: ")
def did_open(path: str) -> None

Notifies the language server that a file has been opened.

This method should be called when a file is opened in the editor to enable language features like diagnostics and completions for that file. The server will begin tracking the file’s contents and providing language features.

Arguments:

  • path str - Absolute path to the opened file.

Example:

# When opening a file for editing
lsp.did_open("/workspace/project/src/index.ts")
# Now can get completions, symbols, etc. for this file

LspServer.did_close

@intercept_errors(message_prefix="Failed to close file: ")
def did_close(path: str) -> None

Notify the language server that a file has been closed.

This method should be called when a file is closed in the editor to allow the language server to clean up any resources associated with that file.

Arguments:

  • path str - Absolute path to the closed file.

Example:

# When done editing a file
lsp.did_close("/workspace/project/src/index.ts")

LspServer.document_symbols

@intercept_errors(message_prefix="Failed to get symbols from document: ")
def document_symbols(path: str) -> List[LspSymbol]

Gets symbol information (functions, classes, variables, etc.) from a document.

Arguments:

  • path str - Absolute path to the file to get symbols from.

Returns:

  • List[LspSymbol] - List of symbols in the document. Each symbol includes:
    • name: The symbol’s name
    • kind: The symbol’s kind (function, class, variable, etc.)
    • location: The location of the symbol in the file

Example:

# Get all symbols in a file
symbols = lsp.document_symbols("/workspace/project/src/index.ts")
for symbol in symbols:
print(f"{symbol.kind} {symbol.name}: {symbol.location}")

LspServer.workspace_symbols

@deprecated(
reason=
"Method is deprecated. Use `sandbox_symbols` instead. This method will be removed in a future version."
)
def workspace_symbols(query: str) -> List[LspSymbol]

Searches for symbols matching the query string across all files in the Sandbox.

Arguments:

  • query str - Search query to match against symbol names.

Returns:

  • List[LspSymbol] - List of matching symbols from all files.

LspServer.sandbox_symbols

@intercept_errors(message_prefix="Failed to get symbols from sandbox: ")
def sandbox_symbols(query: str) -> List[LspSymbol]

Searches for symbols matching the query string across all files in the Sandbox.

Arguments:

  • query str - Search query to match against symbol names.

Returns:

  • List[LspSymbol] - List of matching symbols from all files. Each symbol includes:
    • name: The symbol’s name
    • kind: The symbol’s kind (function, class, variable, etc.)
    • location: The location of the symbol in the file

Example:

# Search for all symbols containing "User"
symbols = lsp.sandbox_symbols("User")
for symbol in symbols:
print(f"{symbol.name} in {symbol.location}")

LspServer.completions

@intercept_errors(message_prefix="Failed to get completions: ")
def completions(path: str, position: Position) -> CompletionList

Gets completion suggestions at a position in a file.

Arguments:

  • path str - Absolute path to the file.
  • position Position - Cursor position to get completions for.

Returns:

  • CompletionList - List of completion suggestions. The list includes:
    • isIncomplete: Whether more items might be available
    • items: List of completion items, each containing:
    • label: The text to insert
    • kind: The kind of completion
    • detail: Additional details about the item
    • documentation: Documentation for the item
    • sortText: Text used to sort the item in the list
    • filterText: Text used to filter the item
    • insertText: The actual text to insert (if different from label)

Example:

# Get completions at a specific position
pos = Position(line=10, character=15)
completions = lsp.completions("/workspace/project/src/index.ts", pos)
for item in completions.items:
print(f"{item.label} ({item.kind}): {item.detail}")
