Overview

• Introduction about IDE’s

• Eclipse example: overview

• Eclipse: editing

• Eclipse: using a version control tool

• Eclipse: compiling/building/generating doc

• Eclipse: running/debugging

• Eclipse: testing

• Eclipse: tools to easily re-write code

• Conclusion

What is an IDE

• IDE = Integrated Development Environment• IDE = EDI (Environnement de Développement Intégré) in French

• Generally language dependant (c/c++ specific IDE, java specific IDE, not yet good ones for Fortran)

• Typical integrated development tools :• editor (with auto-indent, auto-completion, colorization, …) ;• version control ;• compiler/builder ;• documentation extractor ;• debugger ;• tests tool ;• refactoring tools.

4

What is not an IDE

• Just a great text editor

• A code generator

• A GUI designer

• A forge (i.e. GForge)

IDEs examples - Java

• Eclipse (http://www.eclipse.org)• JBuilder (http://www.borland.com/us/products/jbuilder/index.html -

free for personnal and non-commercial use)• NetBeans (http://www.netbeans.org/)• JCreator (http://www.jcreator.com/)• …

Eclipse software

• Foundation: http://www.eclipse.org & http://www.eclipse.org/org/index.html

• Downloads at http://www.eclipse.org/downloads/index.php

• Common Public License (CPL):• http://www.eclipse.org/legal/cpl-v10.html• royalty free source code / world wide redistribution rights

• Supported languages: Java, C++, python, …

• Supported platforms: Linux, Windows, … (java software)

• Many tutorials on the web• A good one (in French):

Eclipse “philosophy”

• Extensible with java plug-ins• May be used with several programming languages via plug-ins• Many specific extensions via plug-ins

• Aim: software factory• MDA• Code generation

10

Eclipse main features

• Powerful editing mode• automatic indentation• search/replace• auto-completion (classes, methods, …)• …

• Version control• CVS

• Compiling/building• its own system• ant

• Debugging• its own debugger

• Testing• JUnit

• Refactoring

Editing with Eclipse: main functionalities

13

Edition with Eclipse: demonstration

• Open a project of vehicles:• Contains simple class MotorizedVehicle• Contains a first inherited class Car• Contains a second inherited class Motorcycle

– Indent properly class Motorcycle• Contains class TestVehicles with a main function

• Other manipulations:• Create new class Plane with inherited methods• Show that changing class name warns if file name is not changed• Add a task in the border• Change the javadoc comments for the file and class• Remove corresponding tasks• Add specific attribute: private float altitude• Add javadoc comment• Show javadoc preview in the bottom window• Automatically add constructor using fields• Show Brackets matching in the border• Show show/hide button in the border• Automatically add getters and setters• Add specific methods goDown and goUp: show automatic completion with this.setAltitude

Configuring CVS access• Check compatibility with CVS version

http://dev.eclipse.org/viewcvs/index.cgi/platform-vcm-home/docs/online/html-cvs/cvs-compatibility.html?rev=1.3

• Window• Open Perspective → Other

• In CVS Repository• Click on “add cvs repository”

16

Using CVS in Eclipse: demonstration

• Checkout an existing project (e.g. dream web pages)

• Modify this project (e.g. add a comment in a web page)

• Commit changes

18

Configuring compiling/building• By default, an Eclipse project is compiled internally

• Project → Properties

19

Using compiling/building: demonstration

20

Using a build.xml

• It is possible to use ant with xml build files• For specific build tasks• To set a given version of the compiler, javadoc, …• To set specific parameters for building (i.e., on a shared project with

people not under Eclipse, …)• Cf. Ant and Eclipse tutorial:

http://perso.wanadoo.fr/jm.doudoux/java/dejae/chap009.htm#chap_9• Cf. Ant documentation:

http://ant.apache.org/manual/index.html

21

Configuring javadoc

• Give path to javadoc at the first go

22

Configuring javadoc (2)

23

Generating javadoc: demonstration

24

Overview









• Conclusion

25

Configuring run/debug

26

Running a java class: demonstration

• Run a class

• Change parameters and run again

27

Debugging: demonstration

• Show run/debug menu

• Add a line breakpoint

• Add a method breakpoint

• View variable value

28

Overview







• Eclipse : testing


• Conclusion

29

Configuring JUnit

• JUnit is a part of the Eclipse project by default

• For more details on how to configure and use JUnit in Eclipse look at http://perso.wanadoo.fr/jm.doudoux/java/dejae/chap010.htm#chap_10

30

Using JUnit: demonstration

• Add a class test for class Motorcycle

• Show Class test for Car

• Show how to run tests

• Modify a test to make it fail

Tools to re-write code: main functionalities

33

Tools to re-write code: demonstration

• Changing a class name

• Changing an attribute name

• Changing a method name

• Changing a method signature

• Moving a method to another class

ConclusionIDE’s:

• Exists for many platforms and programming languages• Java (e.g., Eclipse)• C/C++

• Is useful for beginners as well as for experts

• Is time consumable at the beginning• Learning curve • Several tools need configuring

• Saves time when often used:• Powerful editing mode• CVS plug-in• Code generation• Easy compiling/building/running, related to source files• Easy refactoring

• Still evolving and will be used in the future for• GUI designer• MDA approach
