type stm_doc_type =
  1. | VoDoc of string
  2. | VioDoc of string
  3. | Interactive of Coqargs.top

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 = {
  1. doc_type : stm_doc_type;
    (*

    The STM does set some internal flags differently depending on the specified doc_type. This distinction should disappear at some some point.

    *)
  2. injections : Coqargs.injection_command list;
    (*

    Injects Require and Set/Unset commands before the initial state is ready

    *)
  3. stm_options : AsyncOpts.stm_opt;
    (*

    Low-level STM options

    *)
}

STM initialization options:

type doc

The type of a STM document

val init_process : AsyncOpts.stm_opt -> unit

init_process performs some low-level initialization, call early

val init_core : unit -> unit

init_core snapshorts the initial system state

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).
