Module Tok

The type of token for the Coq lexer and parser

type 'c p =
| PKEYWORD : string -> string p
| PPATTERNIDENT : string option -> string p
| PIDENT : string option -> string p
| PFIELD : string option -> string p
| PNUMBER : NumTok.Unsigned.t option -> NumTok.Unsigned.t p
| PSTRING : string option -> string p
| PLEFTQMARK : unit p
| PBULLET : string option -> string p
| PQUOTATION : string -> string p
| PEOI : unit p
val pattern_strings : 'c p -> string * string option
type t =
| KEYWORD of string
| PATTERNIDENT of string
| IDENT of string
| FIELD of string
| NUMBER of NumTok.Unsigned.t
| STRING of string
| LEFTQMARK
| BULLET of string
| QUOTATION of string * string
| EOI
val equal_p : 'a p -> 'b p -> ('a, 'b) Util.eq option
val equal : t -> t -> bool
val extract_string : bool -> t -> string

Names of tokens, used in Grammar error messages

val token_text : 'c p -> string
val trim_quotation : string -> char option * string

Utility function for the test returned by a QUOTATION token: It returns the delimiter parenthesis, if any, and the text without delimiters. Eg `{{ text

}

}

` -> Some '{', ` text `

val match_pattern : 'c p -> t -> 'c

for camlp5, eg GRAMMAR EXTEND ..... [ IDENT "x" -> .... ] END is a pattern (PIDENT (Some "x"))
