dream-html 3.0.1 · OCaml Package

All standard HTML attributes and tags. Some attributes and tags have the same name, e.g. style. To disambiguate them, attributes have a _ (underscore) suffix.

Attributes

Standard, most non-deprecated attributes from https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes. Where an attribute name conflicts with an OCaml keyword, the name is suffixed with _. Most attributes are constructed by passing in a value of some type.

All string-valued attributes allow formatting (interpolation):

div [id "section-%d" section_id] []

Or plain strings:

p [id "toast"] []

Most boolean attributes are plain values and don't need to be constructed with function calls:

input [required]

However, boolean attributes which may be inherited and toggled on/off in children, are constructed by passing in a value:

div
  [contenteditable true]
  [p [] [txt "Edit me!"]; p [contenteditable false] [txt "Can't edit me!"]]

Enumerated attributes accept specific values:

input [inputmode `tel]

since 1.0.0.

type enctype = [

| `urlencoded
| `formdata
| `text_plain

]

type method_ = [

| `GET
| `POST
| `dialog
(*
- since 2.1.0
*)

]

val null_ : attr

An attribute that will not be rendered in the markup. Useful for conditional logic where you sometimes want to render an attribute and sometimes not.

p[if should_show then null_ else style_ "display:none"][
  txt "Show and tell"]

Tags

HTML tags. Most (standard tags) are constructed by passing a list of attributes and a list of children:

div [id "my-div"] [p [] [txt "Hello"]]

Some (void elements) are constructed only with a list of attributes:

input [required; type_ "email"; name "email-addr"]

Finally, a few (text elements) are constructed with a list of attributes and a single text child:

title [] "Document title"

title [] "My App ・ %s" page_name

script [] {|alert('Careful, this is not escaped :-)');|}

val null : node list -> node

A tag that will not be rendered in the markup. Useful for containing a bunch of child nodes inside a single node without having to litter the DOM with an actual node. Also may be called 'splicing'.

null
  [ p [] [txt "This paragraph."];
    p [] [txt "And this paragraph."];
    p []
      [txt "Are spliced directly into the document without a containing node."]
  ]
