src.tools.core.parsers.non_json_tool_call_parser.NonJSONToolCallParser

Bases: BaseToolCallParser

Parser for extracting non-JSON formatted tool calls from text.

Specializes in parsing tool calls that use custom formats like {args}.

Example

config = {
    "formats": {
        "non_json_format": {
            "function_call_pattern": r'<function=(.*?)>{(.*?)}</function>'
        }
    }
}
parser = NonJSONToolCallParser(config)
result = parser.parse('<function=my_tool>{"arg1": "value"}</function>')
