val encode : ?pos:int -> ?len:int -> ?linelength:int -> ?crlf:bool -> string -> string
If pos
and/or len
are passed, only the substring starting at
pos
(default: 0) with length len
(default: rest of the string)
is encoded.
The result is divided up into lines not longer than linelength
(without counting the line separator); default: do not divide lines.
If linelength
is smaller than 4, no line division is performed.
If linelength
is not divisible by 4, the produced lines are a
bit shorter than linelength
.
If crlf
(default: false) the lines are ended by CRLF; otherwise
they are only ended by LF.
(You need the crlf option to produce correct MIME messages.)
val url_encode : ?pos:int -> ?len:int -> ?linelength:int -> ?crlf:bool -> string -> string
encode
but use slightly different characters that can be
part of URLs without additional encodings.
The encoded string consists only of the characters a-z, A-Z, 0-9,
-, /, .
url_encode
does not implement the Base 64 encoding as described
in the standard!
val decode : ?pos:int ->
?len:int -> ?url_variant:bool -> ?accept_spaces:bool -> string -> string
If pos
and/or len
are passed, only the substring starting at
pos
(default: 0) with length len
(default: rest of the string)
is decoded.
If url_variant
(default: true
) is set, the functions also
accepts the characters '-' and '.' as produced by url_encode
.
If accept_spaces
(default: false
) is set, the function ignores
white space contained in the string to decode (otherwise the
function fails if it finds white space). Furthermore, the character
'>' is considered as "space", too (so you don't have trouble with
mbox mailboxes that accidentally quote "From").
