Read GAMS model file and parse its core structure.

This function reads a GAMS model file or text, expands any included files, removes comments, and parses the core structure into sets, parameters, variables, equations, and aliases, returning a model_structure object.

Usage

read_gams(
  file_or_text,
  include = TRUE,
  interim_file = NULL,
  strict = TRUE,
  verbose = FALSE,
  ...
)

Arguments

file_or_text: A path to a GAMS file or a character vector containing GAMS code.
include: Logical indicating whether to expand included files (default is TRUE).
interim_file: Optional path to an interim file where the processed GAMS code prepended for parsing will be saved. If NULL, no interim file is created.
strict: Logical indicating whether to enforce strict parsing rules (default is TRUE). If FALSE, some undeclared equations may be added to the model structure.
verbose: Logical indicating whether to print verbose output during parsing (default is FALSE).
...: Additional arguments passed to other functions, currently unused.

Value

A model_structure object containing the parsed GAMS model structure, including sets, mappings, aliases, parameters, variables, and equations.
