Module Pa_tyxml

module Pa_tyxml: sig .. end
Syntax extension for HTML or SVG tree creation.


To choose actual XML-implementation you have to provide a module named Html (or Svg):

For example, the following code:

  let open Tyxml in
  << <html>
     <head><title></title></head>
     <body><h1>plop</h1></body>
   </html> >>
)
is a caml value of type
Html_types.html Html.elt
.

In the following, Html is assumed to be an HTML implementation, such as Tyxml.Html, but this could for example also be Eliom's Eliom_content.Html.F.

To compile a module containing this syntax, you need the camlp4 preprocessor:

ocamlfind ocamlc -package tyxml.syntax -syntax camlp4o -c your_module.ml
or
ocamlc -pp "camlp4o -I <path/to/tyxml> pa_tyxml.cmo" -c your_module.ml

You can insert OCaml expressions of type

'a Html.elt
inside html using
$...$
, like this:
let oc = << <em>Ocsigen</em> >> in
<< <p>$oc$ will revolutionize web programming.</p> >>
You can insert OCaml expressions of type string inside HTML using
$str:... $
, like this:
let i = 4 in
<< <p>i is equal to $str:string_of_int i$</p> >>
If you want to use a dollar in your page, just write it twice.

You can write a list of HTML expressions using the syntax

<:htmllist<...>>
, for example:
<:htmllist< <p>hello</p> <div></div> >>

Here are some other examples showing what you can do:

<< <ul class=$ulclass$ $list:other_attrs$>
     $first_il$
     $list:items$
   </ul> >>

Warning: lists antiquotations are allowed only at the end (before a closing tag). For example, the following is not valid:

<< <ul $list:other_attrs$ class=$ulclass$>
     $list:items$
     $last_il$
   </ul> >>

The syntax extension is not allowed in patterns for the while.

Additionnaly, you may use  svg  or  svglist .
