Eclipse - Basics

Workspace The workspace is the physical location (file path) you are working in. You can

All your projects, sources files, images and other artifacts will be stored and saved in your workspace.

Perspective A perspective is a visual container for a set of views and editors.

Views Viewport providing specific information and/or functionality

Working Sets Group elements for display in views or for operations on a set of elements.

PTI & Dynamic Language Toolkit

Creating a Validator

The dynamic language validator will run a php script and interprets the outfit by matching against an regular expression

We are going to build the incredible echo-instead-of-print Validator

Window -> Preferences -> Dynamic Languages -> Validators -> Add
