The MN8 Interpreter classes which implement the interpreter with the affiliated concepts for the MN8 scripting language. MN8 is a tool which employs a concept (object) oriented scripting language with querying facilities, tightly integrated with the web with the sole purpose of information extraction and manipulation.

The MN8 interpreter is composed from:

core interpreter classes:

Consisting from the org.media.mn8 and org.media.mn8.parser packages are responsible for the parsing and interpretation of MN8 script code. Also this packages contains the basic implementation of interpreter related functionalities (method, concept, interpreter, stack, scope, concept and so on).

interpreter configuration classes:

Consisting from the org.media.mn8.conf package. Classes responsible for loading the configuration options from /conf/mn8Config.xml and configuring the interpreter according to it.

the core MN8 concepts:

Consisting from the org.media.mn8.concepts package. This classes implement the MN8 basic concepts/objects. Those represent the core objects available to a developer to use in an MN8 based script file, concepts like: String, Element, Attribute, HTMLPage and so on.

concepts helper classes:

Consisting from the org.media.mn8.protocol.* packages. This classes implements the URL wrappers and afferent classes so that MN8 concepts will become available for handling other protocols than the default Java provided ones. This packages support the Java naming conventions exposed in the URL.URL(java.net.URL, java.lang.String, java.net.URLStreamHandler) documentation and most of them implements the URLConnection and URLStreamHandler interfaces.

diverse helper classes:

Consisting from the org.media.mn8.util,org.media.mn8.util.tar and org.media.mn8.util.textparser packages. This classes implements diverse utilitarian objects for helping in parsing and interpretation, compressing using tar and parsing general text files.

HyperPad SWING based editor:

Consisting from the org.media.hyperpad,org.media.hyperpad.gui and org.media.hyperpad.conf packages. This classes implements and interesting SWING based editor/interpeter in order to be able to have an alternative for the command line based mn8 tool. The tool is based on the HTML widget therefore is able to render the HTML code generated by an MN8 based script.
