The STM document type stm_doc_type determines some properties such as what uncompleted proofs are allowed and what gets recorded to aux files.

type stm_init_options = {
doc_type : stm_doc_type;
iload_path : Loadpath.coq_path list;
require_libs : (string * string option * bool option) list;
stm_options : AsyncOpts.stm_opt;
}

Coq initialization options:

  • doc_type: Type of document being created.
  • require_libs: list of libraries/modules to be pre-loaded at startup. A tuple (modname,modfrom,import) is equivalent to From modfrom Require modname; import works similarly to Library.require_library_from_dirpath, Some false will import the module, Some true will additionally export it.
type doc

The type of a STM document

val init_core : unit -> unit

init_core performs some low-level initialization; should go away in future releases.

val new_doc : stm_init_options -> doc * Stateid.t

new_doc opt Creates a new document with options opt

val parse_sentence : doc:doc -> Stateid.t -> entry:(Pvernac.proof_mode option -> 'a Pcoq.Entry.t) -> Pcoq.Parsable.t -> 'a

parse_sentence sid entry pa Reads a sentence from pa with parsing state sid and non terminal entry. entry receives in input the current proof mode. sid should be associated with a valid parsing state (which may not be the case if an error was raised at parsing time).
