Combinators

Lexing

val peek : state -> state * Located_token.t option

peek state is (state', token_opt) where token_opt is the next unconsumed token in state. If token_opt = Option.None, then the end of the input stream was reached. Otherwise, token_opt = Option.Some token. The token is not consumed, meaning that state' is not advanced to the next token in the stream.

val observe : state -> state * Located_token.t option

observed state is like peek state, but the observed token is consumed.

val accept : state -> state * unit

accept state is (state', ()) where state' is derived from state by consuming the next token in the input stream. This effectively observes and discards the next token in state.

val insert : Located_token.t -> state -> state * unit

insert token state is (state', ()) where state' is derived from state by inserting token at the beginning of the input stream. That is, token is the next token in state'.

Locations

val next_location : state -> state * Beluga_syntax.Location.t option

next_location state is (state', next_location_opt) where next_location_opt is the location of the next token in state. This does not advance the input stream. next_location_opt = Option.None at the end of the input stream.

val previous_location : state -> state * Beluga_syntax.Location.t option

previous_location state is (state', previous_location_opt) where previous_location_opt is the location of the last token in state to have been consumed. previous_location_opt = Option.None at the beginning of the input stream.

Backtracking

val enable_backtracking : state -> state * unit

enable_backtracking state is (state', ()) where state' has backtracking enabled.

val disable_backtracking : state -> state * unit

enable_backtracking state is (state', ()) where state' has backtracking disabled.

val can_backtrack : state -> state * bool

can_backtrack state is (state', flag) where flag = true indicates that state and state' allow backtracking out of an erroneous result, and flag = false otherwise.

val allow_backtracking_on_error : 
  (state -> state * ('a, 'e) Stdlib.result) ->
  state ->
  state * ('a, 'e) Stdlib.result

allow_backtracking_on_error m is m' such that m' state is (state', x) with backtracking enabled in state' if x = Result.Error cause. That is, this combinator enables backtracking if m' produces an error. Backtracking then needs to be manually disabled afterwards.

val with_checkpoint : 
  (state -> state * ('a, 'e) Stdlib.result) ->
  state ->
  state
  * ('a, [> `Backtracked of 'e | `Did_not_backtrack of 'e ]) Stdlib.result

with_checkpoint m is m' such that m' state marks the current state, performs m, then either

discards the marked state if m state = (state', Result.Ok x),
backtracks to the marked state if m state = (state', Result.Error cause).

The output error from m is additionally annotated with whether backtracking occurred.

In the case of a parser m, backtracking can occur if backtracking is enabled with allow_backtracking_on_error, or if m did not consume any input.

val run : 'a t -> state -> state * ('a, exn) Stdlib.result

run p state is (state', result) where result is the output of parsing p using state.

This is only meant to be used internally, or when defining new parser combinators, since it does not prune the parser exception when result = Result.Error exn.

The end user of a parser should use run_exn.

val run_exn : 'a t -> state -> state * 'a

run_exn p state is (state', parsed) where parsed is the object parsed from state using p. A pruned exception is raised if p fails.

val eval_exn : 'a t -> state -> 'a

eval_exn p state runs p on state like run_exn, and discards the output parser state. This is used whenever we do not resume parsing from the final parser state, particularly when using the only combinator since we expect the end of the input stream to be reached.

val catch : 
  'a t ->
  ((state * ('a, exn) Stdlib.result) -> state * ('b, exn) Stdlib.result) ->

catch p runs p and invokes the given handler to modify the outcome. Despite being called "catch", this parser is actually a kind of map, and is used to implement "low-level" parser transformations.

val fail : exn -> 'a t

fail exn is the parser that always fails with exn.

val fail_at_location : Beluga_syntax.Location.t -> exn -> 'a t

fail_at_previous_location exn is the parser that always fails with exn annotated with the previous location in the input stream.

val labelled : string -> 'a t -> 'a t

labelled label p is p' such that when p fails, p' annotates the exception with a label for error-reporting.

val span : 'a t -> (location * 'a) t

span p is the parser p' that additionally returns the source file location that spans the tokens consumed by p.

val only : 'a t -> 'a t

only p is the parser p' that expects p to succeed, then the end of input to be reached immediately after.

val maybe : 'a t -> 'a option t

maybe p is the parser p' that may fail, in which case it returns Option.none.

val void : 'a t -> unit t

void p is the parser p' that discards the result of p.

val many : 'a t -> 'a list t

many p is the parser p' that parses tokens following the EBNF grammar p*, meaning that it parses 0 or more occurrences of p.

val some : 'a t -> 'a Support.List1.t t

some p is the parser p' that parses tokens following the EBNF grammar p+, meaning that it parses 1 or more occurrences of p.

val sep_by0 : sep:unit t -> 'a t -> 'a list t

sep_by0 ~sep p is the parser p' that parses tokens following the EBNF grammar [p (sep p)*], meaning that it parses 0 or more occurrences of p separated by sep.

val sep_by1 : sep:unit t -> 'a t -> 'a Support.List1.t t

sep_by1 ~sep p is the parser p' that parses tokens following the EBNF grammar p (sep p)+, meaning that it parses 1 or more occurrences of p separated by sep.

val trying : 'a t -> 'a t

trying p is the parser p' that enables backtracking in the parser state if p fails, which signals that the erroneous state can be backtracked out of irrespective of the number of consumed tokens.

val choice : 'a t Support.List.t -> 'a t

choice ps is the parser p that sequentially tries the parsers in p.

For instance, choice [p1; p2] first runs p1. If it fails, p2 is run if one of the following is true.

p1 failed without consuming any input.
p1 failed with backtracking enabled. Backtracking is enabled by the trying combinator.

val alt : 'a t -> 'a t -> 'a t

alt p1 p2 is choice [p1; p2].

val satisfy : (token option -> ('a, exn) Stdlib.result) -> 'a t

satisfy f is the basic parser p that performs an action based on whether the next token in the stream satisfies the predicate f. The parser is advanced only if the next token satisfies f. If the next token does not satisfy the predicate, then the error is annotated with the next token's location.

val eoi : unit t

eoi is the parser that expects the end of input to be reached. This is either the end of the input string, token stream, or file input channel.
