Module Pxp_lexing


module Pxp_lexing: sig .. end
The following types and functions are the same as in the module Lexing of the stdlib. For some versions of O'Caml, some of the functions have a more efficient implementation.

type lexbuf = Lexing.lexbuf 
val from_channel : Pervasives.in_channel -> lexbuf
val from_string : string -> lexbuf
val from_function : (string -> int -> int) -> lexbuf
val lexeme : lexbuf -> string
val lexeme_char : lexbuf -> int -> char

val lexeme_start : lexbuf -> int

val lexeme_end : lexbuf -> int

Extensions:
val lexeme_len : lexbuf -> int
val from_string_inplace : string -> Lexing.lexbuf
Similar to Lexing.from_string, but does not copy the passed string intially
val from_another_string_inplace : Lexing.lexbuf -> string -> unit
lexbuf: a buffer from a previous Lexing.from_string (or from_string_inplace). Modifies lexbuf such that the lexer starts again with the passed string
val sub_lexeme : Lexing.lexbuf -> int -> int -> string
Same as String.sub (Lexing.lexeme lexbuf) k l, but avoids one string allocation
