Convert a multimod AST node to Pyomo syntax

Source: R/as_pyomo.R
as_pyomo.Rd

This helper mirrors as_jump() but emits Python/Pyomo-friendly strings. The implementation focuses on linear expressions (sum/prod, arithmetic operators, variable/parameter references) which cover the current OSeMOSYS workflow. Unsupported node types raise informative errors so we can extend coverage incrementally.

Usage

as_pyomo(x, ...)

Arguments

x

An AST node (e.g. equation, expression, variable, parameter).

...

Additional arguments used internally:

  • model: multimod model for alias lookups.

  • var_names: named vector mapping base set names to iterator aliases (used when emitting constraint bodies).

  • scope: local iterator scope for nested aggregations.

Value

Character string containing Pyomo-compatible code.
