type search_flags = (search_constraint * bool) list

A list of search constraints; the boolean flag is set to false whenever the flag should be negated.

type 'a coq_object = {
  1. coq_object_prefix : string list;
  2. coq_object_qualid : string list;
  3. coq_object_object : 'a;
}

A named object in Coq. coq_object_qualid is the shortest path defined for the user. coq_object_prefix is the missing part to recover the fully qualified name, i.e fully_qualified = coq_object_prefix + coq_object_qualid. coq_object_object is the actual content of the object.

type coq_info = {
  1. coqtop_version : string;
  2. protocol_version : string;

type location = (int * int) option
type state_id = Stateid.t
type route_id = Feedback.route_id
type edit_id = int
type 'a value =
  1. | Good of 'a
  2. | Fail of state_id * location * Pp.t
type ('a, 'b) union = ('a, 'b) Util.union
type add_sty = (string * edit_id) * (state_id * verbose)

add ((s,eid),(sid,v)) adds the phrase s with edit id eid on top of the current edit position (that is asserted to be sid) verbosely if v is true. The response (id,(rc,s) is the new state id assigned to the phrase. rc is Inl if the new state id is the tip of the edit point, or Inr tip if the new phrase closes a focus and tip is the new edit tip

s used to contain Coq's console output and has been deprecated in favor of sending feedback, it will be removed in a future version of the protocol.

type add_rty = state_id * ((unit, state_id) union * string)
type edit_at_sty = state_id

edit_at id declares the user wants to edit just after id. The response is Inl if the document has been rewound to that point, Inr (start,(stop,tip)) if id is in a zone that can be focused. In that case the zone is delimited by start and stop while tip is the new document tip. Edits made by subsequent add are always performed on top of id.

type edit_at_rty = (unit, state_id * (state_id * state_id)) union
type query_sty = route_id * (string * state_id)

query s id executes s at state id.

query used to reply with the contents of Coq's console output, and has been deprecated in favor of sending the query answers as feedback. It will be removed in a future version of the protocol.

type query_rty = unit
type goals_sty = unit

Fetching the list of current goals. Return None if no proof is in progress, Some gl otherwise.

type goals_rty = goals option
type evars_sty = unit

Retrieve the list of uninstantiated evars in the current proof. None if no proof is in progress.

type evars_rty = evar list option
type hints_sty = unit

Retrieving the tactics applicable to the current goal. None if there is no proof in progress.

type hints_rty = (hint list * hint) option
type status_sty = bool

The status, for instance "Ready in SomeSection, proving Foo", the input boolean (if true) forces the evaluation of all unevaluated statements

type status_rty = status
type search_sty = search_flags

Search for objects satisfying the given search flags.

type search_rty = string coq_object list
type proof_diff_sty = string * Stateid.t

Diffs between the proof term at a given stateid and the previous one

type proof_diff_rty = Pp.t
type db_cmd_sty = string

A debugger command

type db_cmd_rty = unit
type get_options_sty = unit

Retrieve the list of options of the current toplevel

type get_options_rty = (option_name * option_state) list
type set_options_sty = (option_name * option_value) list

Set the options to the given value. Warning: this is not atomic, so whenever the call fails, the option state can be messed up... This is the caller duty to check that everything is correct.

type set_options_rty = unit
type mkcases_sty = string

Create a "match" template for a given inductive type. For each branch of the match, we list the constructor name followed by enough pattern variables.

type mkcases_rty = string list list
