HTML attributes.

See the attribute constructors.

Attributes

type name = string

The type for attribute names.

type t

The type for attributes.

val v : name -> string -> t

v n value is an attribute named n with value value. Favour use of attribute constructors whenever possible.

val void : t

void is v "" "", an attribute that doesn't get rendered. See also is_void.

val int : name -> int -> t

int n i is v n (string_of_int i).

val true' : name -> t

true' n is v n "". This sets the boolean attribute n to true. The attribute must be omitted to be false. See also if' and if_some.

val if' : bool -> t -> t

if' cond at is if cond then at else void.

val if_some : t option -> t

if_some o is at if o is Some at and void if o is None.

Predicates and comparisons

val is_void : t -> bool

is_void at is true iff the name of at is empty. These attributes render nothing. See also void.

val equal : t -> t -> bool

equal at0 at1 is true if both the name and value of at0 and at1 are String.equal.

val compare : t -> t -> int

compare is a total order on attributes compatible with equal.

Converting and formatting

val to_pair : t -> string * string

to_pair at is (n, v) the name and value of the attribute.

val of_pair : (string * string) -> t

of_pair (n, value) is v n value.

val pp : Stdlib.Format.formatter -> t -> unit

pp ppf at formats at on ppf using HTML syntax. is_void attributes format nothing.

Attribute constructors

See the MDN HTML attribute reference.
