Module BatCharParser

module BatCharParser: sig .. end
Parsing character strings.

This module defines common functions for parsing character strings, encoded in Latin-1. These functions are meant to be used in conjunction with the ParserCo module.

Note As ParserCo, this module is still very rough and needs testing.

type position = {
   offset : int; (*
Offset on the line (starting at 0)
*)
   line : int; (*
Line number (starting at 0)
*)
}
The position inside one file or one stream.
val advance : char -> position -> position
Advance by one char.

advance c p returns a new position advanced by one char. If c is '\r' or '\n', the result is {offset = 0; line = p.line + 1}. Other wise, the result is {offset = p.offset + 1; line = p.line}.

val source_of_string : string -> (char, position) BatParserCo.Source.t
Create a source from a latin-1 character string.
val source_of_enum : char BatEnum.t -> (char, position) BatParserCo.Source.t
Create a source from a latin-1 character.
val parse : (char, 'a, position) BatParserCo.t ->
string ->
('a, position BatParserCo.report) BatPervasives.result
Apply a parser to a string.

Utilities

val char : char -> (char, char, position) BatParserCo.t
Recognize exactly one char
val none_of : char list -> (char, char, position) BatParserCo.t
Accept any value not in a list As ParserCo.none_of, just with improved error message.
val not_char : char -> (char, char, position) BatParserCo.t
Accept any value not a given char As none_of.
val string : string -> (char, string, position) BatParserCo.t
Recognize exactly one string
val case_char : char -> (char, char, position) BatParserCo.t
As char, but case-insensitive
val case_string : string -> (char, string, position) BatParserCo.t
As case_string, but case-insensitive
val newline : (char, char, position) BatParserCo.t
Recognizes a newline
val whitespace : (char, char, position) BatParserCo.t
Recognizes white-space
val uppercase : (char, char, position) BatParserCo.t
Recognizes one upper-case ASCII character, including accentuated characters.
val lowercase : (char, char, position) BatParserCo.t
Recognizes one lower-case ASCII character, including accentuated characters.
val letter : (char, char, position) BatParserCo.t
Recognizes one lower- or upper-case ASCII character, including accentuated characters.
val uppercase_latin1 : (char, char, position) BatParserCo.t
Recognizes one upper-case Latin-1 character, including accentuated characters.
val lowercase_latin1 : (char, char, position) BatParserCo.t
Recognizes one lower-case Latin-1 character, including accentuated characters.
val latin1 : (char, char, position) BatParserCo.t
Recognizes one lower- or upper-case Latin1 character, including accentuated characters.
val digit : (char, char, position) BatParserCo.t
Recognizes one decimal digit
val hex : (char, char, position) BatParserCo.t
Recognizes one hexadecimal digit (case-insensitive)
