Introduction to the IDE

One development window divided into four panels: Editor Context tool Clusters pane Features pane+ Search and Favorites

Toolbar customization

Pick-and-drop mechanism


9


The editor

Syntax highlighting Syntax completion (CTRL+Space) Class name completion (SHIFT+CTRL+Space) Smart indenting Block indent or exdent Block commenting or uncommenting Infinite level of Undo/Redo (reset after a save) Quick search features (F3 and SHIFT+F3)


10


The compiler

Fast Produces efficient code Supports .NET Project Settings Tool

The Diagram tool

Provides “Real time” roundtrip reverse engineering Synchronized at each compilation Allows for different views


15


EiffelStudio



16


Documentation generation

Multiple predefined formats Extendible formats Extremely powerful HTML generation with

clickable diagrams


17


Metrics

Hundreds of different metrics available Can be publicized on web sites for future

comparison

19


Getting started with the debugger

The system must be melted/frozen (finalizedsystems cannot be debugged)

Use the Project Settings Tool to specify commandline arguments

Click the launch button


20


Setting breakpoints

Use the flat formats to add breakpoints Tip: An efficient way of adding breakpoints

consists in dropping a feature in the context tool Click in the margin to enable/disable single

breakpoints Use the toolbar debug buttons to enable or

disable all breakpoints globally


21


Running the application

New display of the Development Window to includedebugging information about: The current object (Object Tool) The arguments to the function being debugged (local

variables)

Possibility to control the number of elements the debuggerdisplays for special objects (Arrays, Strings)

Once on a breakpoint: possibility to step over / into / outnext statement

Possibility to interrupt the application at anytime (PauseApplication button or SHIFT+CTRL+F5)
