type var =

|	VarTable of table_row list	(*	::table(tag)::	*)

type table_row = (string * var) list 

Variables are either simple string, tables, conditionals or callbacks.

A simple string is set with template#set "name" s where s will be automatically escaped depending on the declaration in the template:

• ::name:: does no escaping;
• ::name_url:: escapes for URL encoding, make it suitable in a link <a href="::name_url::">;
• ::name_html:: escapes for HTML display of the string;
• ::name_html_tag:: escapes the string to make it suitable to be placed between quotes in an HTML tag, e.g. <input value="::name_html_tag::">;
• ::name_html_textarea:: escapes the string to make it suitable to be placed between <textarea>...</textarea>.

Tables are declared in the template by ::table(name):: row template ::end::. The row template can contain other variables. Calling template#table "name" rows, where rows is a list [row1, row2,...,rowN], will insert N row templates with each template having its variables set thanks to row1,... each of which is an associative list name -> value (of type Template.table_row).

Conditionals are declared in the template by ::if(name) .. ::else:: .. ::end:: with the "else" clause being optional. Calling template#conditional sets up a conditional value.

Calling template#callback "fname" f sets up the callback function declared by ::call(fname,arg1,...,argN):: replacing the call by the value of f applied to the list [arg1,...,argN]. The string returned by f can be escaped by using suffices in the template as for simple tags: ::call(fname,arg1,...,argN)_html::,...

A template may also include other templates with ::include(filename)::.

class template : ?filename:string -> string -> object .. end

val template : string -> template

val template_from_string : ?filename:string -> string -> template

val template_from_channel : ?filename:string -> Pervasives.in_channel -> template
