app.processing.pre
==================

.. py:module:: app.processing.pre

.. autoapi-nested-parse::

   Each single qasm snippet attached to a node will first pass through the preprocessing pipeline.

   This happens without the global graph view.
   The steps are:

   - parse implementation if it is a string
   - convert to OpenQASM 3 if in OpenQASM 2
   - rename the identifiers by prefixing with node id
   - inline constants
   - parse annotation info
   - upcast inputs if they are too small for the required spec

.. py:function:: preprocess(node: app.processing.graph.ProgramNode, implementation: str | openqasm3.ast.Program, requested_inputs: dict[int, app.model.data_types.LeqoSupportedType] | None = None) -> app.processing.graph.ProcessedProgramNode

   Run an openqasm3 snippet through the preprocessing pipeline.

   :param node: The node to preprocess.
   :param implementation: A valid OpenQASM 2/3 implementation for that node.
   :param requested_inputs: Optional inputs specification for size_casting
   :return: The preprocessed program.
