Installation

Start the engines Set current language System -> Systemverwaltung -> Sprachunterstützung Open Anwendungen -> Zubehör -> Terminal #> cd IPC09_Workshop ¶ #> sudo chown -R ubuntu:ubuntu workspace ¶ #> ./bin/eclipse/eclipse ¶

Eclipse - Basics  Workspace  The workspace is the physical location (file path) you are working in. You can choose the workspace during startup of eclipse or via the menu (File-> Switch Workspace-> Others).  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.

Your Choice …  External Tools  SVN and PDT  Shortcuts  Templates  PTI (PHP Tool Integration)  Validators  Xdebug

Eclipse - Shortcuts Shortcut Description CTRL-ALT-Cursor Copy the current line CTRL-Left/Right Jump to previous/next courser position CTRL-Up/Down Move marked text SHIFT-ALT-A Toggle block edit and normal mode STRG-SHIFT-T Open the „Open Type“ box STRG-SHIFT-C Comment the marked text using „//“ ALT-ENTER Maximize Editor To edit the shortscuts Window -> Preferences -> General -> Keys

Templates Contextual predefined code snippets Configure at Preferences > PHP > Templates

File Templates Creating a prefilled file when using the „new PHP File“ dialog Window -> Preferences -> PHP -> Editor -> Tempalates

Code Templates Eases typing of complex code structures (e.g. foreach statement)  Activation key: <CTRL> + space

Validators Validators are plugins that can analyse files and set markers (e.g. Warnings, Errors)  They can be switched off!  Validators can be run manual or on build  Most native PDT validators are syntax checkers  It is possible to add validators written in PHP Window -> Preferences -> Validation

PTI & Dynamic Language Toolkit  Eclipse Plugins für Eclipse PDT 2.x und Zend Studio 7.x  Ziel: Direkte Nutzung von PHP Tools in Eclipse PDT  Aktuelle Unterstützung:  PHP_CodeSniffer  PHPDepend  PHPUnit  PHP Copy / Paste Detector  PEAR Verwaltung inkl. aktueller PEAR Bibliothek  Erweitert Eclipse DLTK External Checker um direkte Nutzung von PHP Skripten  Open Source (EPL)

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

Subversion (client configuration)  Set „auto-properties“  WinXp: C:Dokumente & Einstellungen<USER>AnwendungsdatenSubversionconfig  MacOs / Linux: ~/.subversionconfig [miscellany] global-ignores = *.o *.lo *.la #*# .*.rej *.rej .*~ *~ .#* .DS_Store .project .cache .settings enable-auto-props = yes [auto-props] *.js = svn:eol-style=LF;svn:keywords=Id LastChangedDate LastChangedRevision URL *.css = svn:eol-style=LF;svn:keywords=Id LastChangedDate LastChangedRevision URL *.php = svn:eol-style=LF;svn:keywords=Id LastChangedDate LastChangedRevision URL *.html = svn:eol-style=LF;svn:mime-type=text/html;svn:keywords=LastChangedDate LastChangedRevision URL *.htm = svn:eol-style=LF;svn:mime-type=text/html;svn:keywords=LastChangedDate LastChangedRevision URL *.xsl = svn:eol-style=LF *.xml = svn:eol-style=LF *.xsd = svn:eol-style=LF

Subversive (installation) • Eclipse update site http://download.eclipse.org/technology/subversive/0.7/update-site/

Subversion (client configuration) • SVN connector • SVN properties for new files • Customize label decorations

Subversion & Subversive  Setup  Common handling  Checkout  Commit / revert changes  Conflict handling  Extended usage  Branching, tagging, merging, patching

External Tools Running external tools inside Eclipse Run -> External Tools -> External Tools Configuration

Build Script Running a script that creates the PHPDoc documentation files <project name="Workshop" basedir="." default="build"> <description> simple example build file </description> <target name="documentation"> <exec executable="phpdoc"> <arg value="-s wp-content/Plugins/PushWP/ -d docs" /> </exec> </target> <target name="build" depends="documentation" /> </project>

Code Beautifier The one missing thing in PDT

Debugging  Debugging techniques  Xdebug  How to enable Eclipse for debugging

Debugging techniques Local debugging

Debugging techniques (II) • Remote debugging

Debugging techniques (III) • Multi-User Debugging – Only possible using Remote Debugging – DBGp Proxy necessary

Xdebug  Debugging for PHP by Derick Rethans (http://www.xdebug.org)  Provides profiling, tracing, code coverage, …  Cross platform

Obtaining Xdebug  PECL  Download from xdebug.org  Installation support at http://xdebug.org/find-binary.php  Package system of Linux distribution

Xdebug configuration Add to php.ini (e.g. on Mac) [XDebug] ;; Only Zend OR (!) XDebug zend_extension="/usr/lib/php/php5/extensions/no-debug-non-zts-20060613/xdebug.so" xdebug.remote_enable=true xdebug.remote_host=127.0.0.1 ;if debugging on remote server, put client IP here xdebug.remote_port=9000 xdebug.remote_handler=dbgp ;; profiler xdebug.profiler_enable=Off xdebug.profiler_enable_trigger=On xdebug.profiler_output_dir=/data_lokal/temp/xdebug/profiling

Xdebug configuration (II) .htaccess - file #-------------------------------# # xDebug section # #-------------------------------# php_value xdebug.remote_enable 1 php_value xdebug.remote_handler bdgp php_value xdebug.remote_host 127.0.0.1 ;if debugging on remote server, put client IP here ;; php_value xdebug.allowed_clients <client IP address> php_value xdebug.remote_port 9000 # profiler php_value xdebug.profiler_enable_trigger 1 php_value xdebug.profiler_enable 0 php_value xdebug.profiler_output_dir "/data_lokal/temp/xdebug/profiling"

Xdebug Hands on

Preferences – Basic setup

General settings  Debug Port  Multisession  DBGp Proxy settings

Preferences – Basic setup

Preferences – PHP servers  Remote debugging  Mapping between IDE and Xdebug

Configuration for remote debugging

Configuration for remote debugging (II)

Configuration for remote debugging (III)

Start a remote debugging session

Start a local debugging

Configure „autostart“ options  Accept JIT  Localhost  Any  Prompt

Debug CLI scripts #> export XDEBUG_CONFIG=“idekey=ECLIPSE_DBGP“↵ #> php myScript.php ↵ #> export XDEBUG_CONFIG=““ ↵ Preconditions  JIT configured  Breakpoint set or 'Break at first line' active Debug cronjobs, PHPUnit tests, etc.

Debugging made easy! Firefox Add-on „Xdebug Helper“
