Pagd

Template. Context. Page.

Overview

Static web site generator, based on well understood MVC - Model, View, Controller - design philosophy. The general idea behind MVC from web application’s perspective is

                           +--------+
                           |template|
                           +--------+
                               |
                               V
+-------+   +----------+    +------+    +-----+
|request|-->|controller|--->|action|<---|model|
+-------+   +----------+    +------+    +-----+
                               |
                               V
                          +---------+
                          |HTML page|
                          +---------+
                               |
                               V
     goes to the client  +-------------+
   <---------------------|http-response|
                         +-------------+

The general idea being that,

  • http request reaches web-application’s controller logic.
  • controller resolves request to web-action by parsing request-URL.
  • the action-logic gathers necessary context information from database models and other sources.
  • a html-template is identified, and the final HTML page is generated using context information from models and page-layout from one or more template files.

pagd follows, more or less, a similar principle to build a web-site from a collection of files organised as a directory tree. Here is a brief idea on how it is done

+------+    +---------+      +-------------+
|layout|--->|generator|<---->|page-iterator|
+------+    +---------+      +-------------+
                 |                  ^
                 |                  |          +------------+
                 V                  +<---------|page-context|
            +---------+             |          +------------+
            |Html-page|             |
            +---------+             |          +-------------+
                 |                  +<---------|page-template|
                 |                  |          +-------------+
                 V            +------------+
            +--------+        |page-content|
            |web-site|        +------------+
            +--------+
