State a rewriter can access

type extra = ..
type config = {
  1. tool_name : string;
  2. include_dirs : string list;
  3. load_path : string list;
  4. debug : bool;
  5. for_package : string option;
    (*

    Additional parameters that can be passed by a caller of rewrite_{signature,structure} to a specific register rewriter.

    *)
  6. extras : extra list;

type cookies

Registering rewriters

type 'types rewriter = config -> cookies -> 'types Migrate_parsetree_versions.get_mapper
val register : name:string -> ?reset_args:(unit -> unit) -> ?args:(Arg.key * Arg.spec * Arg.doc) list -> 'types Migrate_parsetree_versions.ocaml_version -> 'types rewriter -> unit
val registered_args : unit -> (Arg.key * Arg.spec * Arg.doc) list

Return the list of command line arguments registered by rewriters

val reset_args : unit -> unit

Call all the registered reset_args callbacks

Running registered rewriters

val run_as_ast_mapper : string list -> Ast_mapper.mapper
val run_as_ppx_rewriter : unit -> 'a
val run_main : unit -> 'a
