This is a lexing buffer for ulex.
type
exception Error
Lexical error
val from_ulb_lexbuf : Netulex.ULB.unicode_lexbuf -> lexbufCreates a new lexbuf from the unicode_lexbuf. After that,
the unicode_lexbuf must no longer be modified.
val lexeme_start : lexbuf -> intThe character position of the start of the lexeme
val lexeme_end : lexbuf -> intThe character position of the end of the lexeme
val lexeme_length : lexbuf -> intThe length of the lexeme in characters
val lexeme : lexbuf -> int arrayReturns the lexeme as array of Unicode code points
val lexeme_char : lexbuf -> int -> intReturns the code point of a certain character of the lexeme
val sub_lexeme : lexbuf -> int -> int -> int arrayReturns a substring of the lexeme as array of Unicode
code points. The first int is the characater position
where to start, the second int is the number of
characters.
val utf8_lexeme : lexbuf -> stringReturns the lexeme as UTF-8 encoded string
val utf8_sub_lexeme : lexbuf -> int -> int -> stringReturns a substring of the lexeme as UTF-8 encoded
string. The first int is the characater position
where to start, the second int is the number of
characters.
val utf8_sub_lexeme_length : lexbuf -> int -> int -> intSame as String.length(utf8_sub_lexeme args), i.e. returns the number of bytes a certain sub lexeme will have when encoded as UTF-8 string.
