Context module for PocketFlow

Provides a shared context for passing data between nodes in a flow. The context stores JSON data in a key-value table.

Types

PfContext = ref object store*: TableRef[string, JsonNode]: Shared context for flow execution. Stores arbitrary JSON data that can be accessed by any node in the flow.

Procs

proc `[]`(ctx: PfContext; key: string): JsonNode {....raises: [KeyError], tags: [], forbids: [].}: Gets a value from the context by key.

Args: key: The key to look up

Returns: The JSON value associated with the key, or JNull if key doesn't exist
proc `[]=`(ctx: PfContext; key: string; value: JsonNode) {....raises: [], tags: [], forbids: [].}: Sets a value in the context.

Args: key: The key to set value: The JSON value to store
proc hasKey(ctx: PfContext; key: string): bool {....raises: [], tags: [], forbids: [].}: Checks if a key exists in the context.

Args: key: The key to check

Returns: True if the key exists, false otherwise
proc newPfContext(): PfContext {....raises: [], tags: [], forbids: [].}: Creates a new PocketFlow context.

Returns: A new PfContext instance with an empty data table.
