package cmdlang-stdlib-runner
A mutable state that will collect parsing information.
The strategy implemented by the cmdlang runner is to create such parser state, enrich it during a parsing phases using stdlib.arg, and once this is done, return an expression suitable for evaluation.
Initialization
In this part we allocate a parser state for a given parser. Once this is done, the parser must be enriched with information coming from the command line.
val create : 'a Cmdlang_ast.Ast.Arg.t -> 'a t Cmdlang_ast.Ast.or_error_msgParsing
This part is what allows stdlib.arg to performs the expected side-effects within the state.
val positional_state : _ t -> Positional_state.tFinalization
Once the parsing has been done, we can finalize the state and return an evaluation suitable for execution.
val finalize : 'a t -> ('a Arg_runner.t, Arg_state.Parse_error.t) Result.tOn This Page
