An integrated web templating environment

General idea

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|        +------------+
            +--------+

Features

• generates static output, hence can be hosted anywhere.

• pluggable layouts.

  • I am currently using pagd.myblog layout for publishing my blog articles.

  • It is possible to create any number of layout either as part of pagd tool or as separate package.

  • although layouts are encouraged to follow the Model-View-Controller concept explained above, it is upto the layout-plugin to define a structure and meaning of layout’s source directory-tree.

• everything that needs to get done by pagd is done through pagd command line interface.

• command line interface comes with simple sub-commands like,

  • create, to create a new layout.

  • gen, to generate static web site from a source layout.

• sub-commands are plugins and can be extended by implementing pagd.interfaces.ICommand interface.

• to use pagd as python library, refer to script.py module under pagd package.

• only part that cannot be configured, constumized or entirely replaced, is the name of the tool ;)

• License: GPLv3 license

• Requires: Linux, Python-3.x, Pluggdapps.

  • To interpret markdown text, python-markdown needs to be installed.

  • To interpret rst text, docutils needs to be installed.

  • To interpret raw-html, python-lxml needs to be installed.

  • If you need source code highlighting in your rst text, pygments and docutils needs to be installed.

• Status: Core design stable. Not expected to change.

Refer to glossary and documentation for default layout pagd.myblog.

pagd is under development - you can hack the code, contribute back with github. Note that the orginal repository is maintained with mercurial and uses hg-git plugin to publish it on github.
