Create a level at the given position.

Type-safe grammar extension
val epsilon_value : ('a -> 'self) -> ('self, _, 'a) Symbol.t -> 'self option
Extending the parser without synchronization
val grammar_extend : 'a Entry.t -> 'a extend_statement -> unit

Extend the grammar of Coq, without synchronizing it with the backtracking mechanism. This means that grammar extensions defined this way will survive an undo.

Extending the parser with summary-synchronized commands
module GramState : Store.S

Auxiliary state of the grammar. Any added data must be marshallable.

Extension with parsing rules
type 'a grammar_command

Type of synchronized parsing extensions. The 'a type should be marshallable.

type gram_reinit = Gramlib.Gramext.g_assoc * Gramlib.Gramext.position

Type of reinitialization data

type extend_rule =
| ExtendRule : 'a Entry.t * 'a extend_statement -> extend_rule
| ExtendRuleReinit : 'a Entry.t * gram_reinit * 'a extend_statement -> extend_rule
type 'a grammar_extension = 'a -> GramState.t -> extend_rule list * GramState.t

Grammar extension entry point. Given some 'a and a current grammar state, such a function must produce the list of grammar extensions that will be applied in the same order and kept synchronized w.r.t. the summary, together with a new state. It should be pure.

val create_grammar_command : string -> 'a grammar_extension -> 'a grammar_command

Create a new grammar-modifying command with the given name. The extension function is called to generate the rules for a given data.

val extend_grammar_command : 'a grammar_command -> 'a -> unit

Extend the grammar of Coq with the given data.

Extension with parsing entries
type ('a, 'b) entry_command

Type of synchronized entry creation. The 'a type should be marshallable.

type ('a, 'b) entry_extension = 'a -> GramState.t -> string list * GramState.t

Entry extension entry point. Given some 'a and a current grammar state, such a function must produce the list of entry extensions that will be created and kept synchronized w.r.t. the summary, together with a new state. It should be pure.

val create_entry_command : string -> ('a, 'b) entry_extension -> ('a, 'b) entry_command

Create a new entry-creating command with the given name. The extension function is called to generate the new entries for a given data.

val extend_entry_command : ('a, 'b) entry_command -> 'a -> 'b Entry.t list

Create new synchronized entries using the provided data.

val find_custom_entry : ('a, 'b) entry_command -> string -> 'b Entry.t

Find an entry generated by the synchronized system in the current state.

raises Not_found

if non-existent.
