ClaudeCodeSDK.JSON (claude_code_sdk v0.0.1)

View Source

Simple JSON parser for Claude Code SDK.

This module provides a lightweight JSON decoder that doesn't require external dependencies. It first attempts to use Erlang's built-in :json module (OTP 27+), falling back to a manual parser for older versions.

The manual parser handles the basic JSON structures needed for Claude Code messages:

  • Objects (maps)
  • Arrays (lists)
  • Strings
  • Numbers (integers and floats)
  • Booleans and null

Note: The manual parser is simplified and may not handle all edge cases of the JSON specification, but it's sufficient for parsing Claude Code CLI output.
