afnix-us-wax - web application extension service

The Web Application Extension service is an original implementation that provides the support for low level HTTP transaction as well as high level XHTML page generation. The service combines various modules and provides access to the modern generation of web contents.

Page service objects
The XhtmlRoot class is the primary interface to generate xhtml page. The class is derived from the XmlRoot class and the Mimeobject. for this reason, creating a xhtml page is equivalent to add xml nodes to the page. The xhtml version is assumed to be 1.1.

Page creation
The XhtmlRoot constructor takes a string argument which is the title page. When the root page is created, a head and body nodes are automatically created. Once created, it is possible to retrieve the head and body nodes from the root node. The head and body nodes are part of the html node which is automatically instantiated as a XhtmlHtml object. The html node can always be retrieved from the root node with the get-child xml method.

# create a new xhtml page
const page (afnix:wax:XhtmlRoot "AFNIX wax service")
# get the head node
const head (page:get-head)
# get the body node
const body (page:get-body)

The head and body nodes are part of the html node which is automatically instantiated as a XhtmlHtml object. The html node can always be retrieved from the root node with the get-child xml method. The root methods get-head and get-body are convenient methods that ease the page design by eliminating the references to the html node.

# create a new xhtml page
const page (afnix:wax:XhtmlRoot "AFNIX wax service")
# get the html node
const html (page:get-child "html")
# get the head node
const head (html:get-head)
# get the body node
const body (html:get-body)

Page header
The XhtmlHead class is the xml node that handles the xhtml head. The object is automatically created when calling the XhtmlRoot constructor. During the construction process, the head is automatically set with a title. Once created, the head can be filled with meta information and styles. The add-meta method is designed to add meta information, while the add-style add a link node with a style reference to the head.

# add a meta tag
head:add-meta "copyright" "2022"
# add a style path
head:add-style "/style.css"

The add-meta method adds a XhtmlMeta object which is a xml tag node. The first argument is the meta descriptor while the second argument is the meta content. Note that the add-meta method can be simulated by calling the XhtmlMeta constructor and then adding the node to the head node.

# create a meta node
const node (afnix:wax:XhtmlMeta "copyright" "2022")
# add the node to the head
head:add node

The add-style method adds a XhtmlStyle object which is a xml tag node. The string argument is the url style sheet path which gets automatically transformed to the form @import(url). Note that the add-style method can be simulated by calling the XhtmlStyle constructor and then adding the node to the head node.

# create a style node
const node (afnix:wax:XhtmlStyle "/style.css")
# add the node to the head
head:add node

Page body
The XhtmlBody class is the xml node that handles the xhtml body. The object is automatically created when calling the XhtmlRoot constructor. Once created, the body node can be filled with any valid xhtml node. Since the node are initially xml tag node, it is always possible to create a tag by name and set the attributes and child nodes manually.

# create a new xhtml page
const page (afnix:wax:XhtmlRoot "AFNIX wax service")
# get the body node
const body (page:get-body)
# add a node
body:add-child node

Page emission
Since the XhtmlRoot object is a xml root node, the node can be used to write the complete hierarchy. The xml node node provides the write method that write a xml tree into a buffer of an output stream.

# create a new xhtml page
const page (afnix:wax:XhtmlRoot "AFNIX wax service")
# write to the output stream
page:write

Another mechanism for writing the page is to use the fact that the XhtmlRoot class implements also the Mime interface. With this in mind, the XhtmlRoot can be used within the HttpReply. This method is particularly useful when writing automated page generation, such like CGI scripts.

# create a new xhtml page
const page (afnix:wax:XhtmlRoot "AFNIX wax service")
# create an http reply object
const reply (afnix:wax:HttpReply)
# write the page as a mime object
reply:add-buffer page
# write the result to the output
reply:write

Page design objects
The wax service module is designed to provide several object that ease the task of creating a xhtml page. Such objects range from comment to table. Most of the time, the construction is simple the resulting node only need to be added to the page tree. When it comes to add text, the problem is becoming more subtle and is discussed later in this section.

Comment node
Adding a comment is done with the XmlComment class which take the comment string in the constructor. Once created, the comment node can be added to the tree.

# add a comment to the body node
body:add-child (


  afnix:xml:XmlComment "this is a comment")

Node style class
When the xhtml page is combined with the cascaded style sheet (CSS), the xhtml node tag often uses a class name to refer to a particular style. The class style is just a node attribute which can be set with the add-attribute method. However, most of the time, the library provides object which have the style as the first argument in the constructor. For example, the XhtmlDiv constructor take 0 or one argument. With one argument, the string argument is used as the style attribute.

# create a xhtml div with a class attribute
const div (afnix:wax:XhtmlDiv "nice")
# create a xhtml div  and set the class manually
const div (afnix:wax:XhtmlDiv)
div:set-attribute "class" "nice"

Adding text paragraph
Adding text to a page is not a trivial task when it comes to deal with text style. By default, a piece of text is stored in the XmlText node. Using this node is easy. However, in a programming context, its use can become heavy. For this reason, all xml nodes provide the parse method which can be used to add a xml tree to the calling node. When it comes to add text that includes rendering tag, this method is quite handy.

# add a text with some piece in italic
node:parse "this is a <i>simple</i> method"

The XhtmlPara node is the preferred node for adding text to a xhtml page. The node takes optionally the style name in the constructor. A boolean flag can also be used to create an empty paragraph node.

# create a paragraph node with a style
const p (afnix:wax:XhtmlPara "title")
# add some text
p:parse "the paragraph text"

Adding reference
Adding reference or hyperlink to a page is achieved with the XhtmlRef class. Most of the time, the object is built with a uri and a text. when the node has been created, the node can be added to the page tree.

# create a hyperlink
const node (


  afnix:wax:XhtmlRef "http://www.afnix.org" "afnix")
# add the node in a paragraph
p:add-child node

Formatting elements
The XhtmlDiv and XhtmlHr classes are the basic formatting xhtml elements. The XhtmlDiv is a grouping element and the XhtmlHr is a simple horizontal ruler element. Both classes take 0 or one argument which is the style name.

# create a div element
const div (afnix:wax:XhtmlDiv "menu")
# create a ruler element
const hr  (afnix:wax:XhtmlHr)

Managing table
The wax service module provides an extensive support of he xhtml table element. There are basically two strategies for creating a table. One is to use the html elements or the other is to use a print table object and automatically feed the xhtml table. The first method provides a better control while the second one is easier to use.

The table element
The XhtmlTable class is the class that manages xhtml table. As usual, a default style name can be specified in the constructor. Eventually, a default table row and table data default style can also be specified. Such default value are used when creating a new row with the new-row method.

# create an element with a default tr and th/td style
const tbl (afnix:wax:XhtmlTable "text" "text" "text")
# get a new row with a default style
const tr (tbl:new-row)

In the previous example, a table is created with a default style for the table row. When a new row is created, the default style is used for that row. If there is no default style, the row is created without a style. Note that the new-row method takes also a style argument that overwrites the default one.

Building the table
A table is built by adding row and data element into the rows. A row is created with the new-row method or the object can be constructed directly and added to the node with the add-child method. The XhtmlTr class is the table row class.

# get a new row with a default style
trans tr (tbl:new-row)
# create a row directly
trans tr (afnix:wax:XhtmlTr "text")

When a row has been created, the data can be added to the row. Normally, the new-data method is used to create a new table data element. If a default style is defined in the table row, the table data element is built with that style. The new-head method can also be used to create table header element. Again, if a default table header style exists in the table row, the element is built with that style. The XhtmlTd class is the table data class and the XhtmlTh class is the table header class.

# get a new data element
trans td (tr:new-data)
# create new head element
trans th (tr:new-head)

When the table data node has been created, the parse method or the add-child method can be called to add other nodes. another method for building the table is to use the add-table method which uses a print table object. In such case, the table rows and data elements are automatically added in the table.

The table structure
The table can be designed directly with table rows with table headers and table data elements. Another method, which is more structured is to use the table head, table body and table footer elements. The XhtmlThead class is the table head element class. The XhtmlTbody class is the table body element class. The XhtmlTfoot class is the table footer element class. These classes behaves exactly like the XhtmlTable and are in fact all derived from the XhtmlTelem class.

# create a xhtml table
const table (afnix:wax:XhtmlTable "text")
# create a table body
const tbody (


  afnix:wax:XhtmlTable "text" "text" "text")
# add a print tbl in the body
tbody:add-table ptbl
# add the body to the table
table:ad-child tbody

A table caption node can also be set with the set-caption method. The method simply creates a XhtmlCaption node and adds it to the table. The caption text is part of the method call which is used by the caption node constructor. It is also possible to create the caption node by calling the XhtmlCaption constructor and adding it to the table with he add-child method.

# create a xhtml table
const table (afnix:wax:XhtmlTable "text")
# set a table caption
table:set-caption "the afnix table system"

The table structure can also be defined with the XhtmlCgr class which corresponds to the xhtml column group element. The column group element is designed to support the col element that formats the table column.

# create a table
const table (afnix:wax:XhtmlTable "text")
# set the table with to 100%
table:add-attribute "width" "100%"
# create a column group
table:add-child (const xcgr (afnix:wax:XhtmlCgr))
# add a column with 30% width
cgr:add-child (afnix:wax:XhtmlCol "30%")
# add a column with 70% width
cgr:add-child (afnix:wax:XhtmlCol "70%")

XhtmlRoot
The XhtmlRoot class is a xml root node used for the design of a xhtml document page. At construction, the root node is initialized with a default xml processing instruction, and xhmtl node with head and body The head and body nodes can be used to add more nodes in order to build the document.
