Подробное описание

JavaScript code generator for the st2js converter.

Walks the typed IR and emits JavaScript source code compatible with the
UniSet2 JScript extension. Generates:
  - load("uniset2-iec61131.js") import
  - uniset_inputs / uniset_outputs sensor arrays
  - Local variable declarations
  - uniset_on_step() function wrapping the PROGRAM body

Sensor variable substitution:
  - VAR_INPUT variables become in_<SensorName>
  - VAR_OUTPUT variables become out_<SensorName>
  - VAR local variables keep their original names

Функции

generate()

str st2js.codegen.generate	(	IRProgram	program,
		SensorMapping	mapping,
		bool	debug = False )

Generate JavaScript source from a typed IRProgram and sensor mapping.

Args:
    program: The typed IRProgram (after type checking).
    mapping: The sensor mapping configuration.
    debug: If True, emit trace instrumentation and program metadata.

Returns:
    A complete JavaScript source string.

generate_with_stats()

tuple[str, GenerateStats] st2js.codegen.generate_with_stats	(	IRProgram	program,
		SensorMapping	mapping,
		bool	debug = False )

Generate JavaScript source and collect statistics.

Returns:
    Tuple of (JavaScript source string, GenerateStats).
