Working with PDT source code in Eclipse

Which Eclipse version?

To comfortably edit PDT source code and execute it, you can use 'Eclipse IDE for Eclipse Committers', which contains some required plugins (Java Development Tools, Plug-in Development Environment, Git Integration, …). You can download it from [https://www.eclipse.org/downloads/eclipse-packages/ here].

Required plugins

In addition to the plugins bundled with Eclipse, PDT requires other plugins that can be installed via the Help → Install New Software… menu item.

You'll need to add the following software site (you can add them by clicking the Manage button in the Install dialog):

Once you defined the above update sites, you should install these plugins:

  • Category "All Orbit Bundles"
    • Apache Commons Exec Plug-in
  • Category "Business Intelligence, Reporting and Charting"
    • BIRT Framework
  • Category "Dynamic Languages Toolkit (DLTK)"
    • Dynamic Languages Toolkit - Core Frameworks SDK
    • Dynamic Languages Toolkit - Core Lucene Index Frameworks SDK
    • Dynamic Languages Toolkit - Mylyn Integration
  • Category "Dynamic Languages Toolkit (DLTK) Tests"
    • DLTK Core Tests
  • Category "General Purpose Tools"
    • Parallel Tools Platform
    • TM Terminal
  • Category "Modeling"
    • Zest SDK
  • Category "Web, XML, Java EE and OSGi Enterprise Development"
    • Eclipse Web Developer Tools

Importing the PDT projects

To import and prepare the PDT projects in Eclipse:

  • Choose the File → Import… menu item, then choose Team → Team Project Set, and specify to import from the URL https://raw.githubusercontent.com/eclipse-pdt/pdt/master/dev/psf/pdt-dev.psf
  • Select current Target Platform (Window → Preferences menu item, then Plug-in Development → Target Platform, then select 'org.eclipse.php.target.current' and choose Apply and Close)
  • (Optional) Disable API Baselines errors (Window → Preferences menu item, then Plug-in Development → API Baselines, then choose Missing API baseline → Ignore)

Running and debugging PDT

In order to run (and debug) PDT, you can choose the Run → Debug Configurations… menu item, and add a new Eclipse Application. Alternatively, PDT can be run/debug just by selecting one of PDT projects and choose Run As → Eclipse Application from the context menu.

NOTE: Currently because of [https://bugs.eclipse.org/bugs/show_bug.cgi?id=534370 bug 534370] MANIFEST.MF in org.eclipse.php.core plugin can indicate errors, you can ignore them.

You can keep the default settings, but it's very handy to go to the Common tab, and check Debug and Run in the Display in favorites menu checklist (so that you'll be able to launch the debug environment by clicking the Debug or Run icons in the toolbar).

When launching the debug application, a new Eclipse instance will be executed: you can create a new PHP project, and you can place breakpoints and analyze the execution in the Eclipse instance containing the PDT project.

PS: when executing PDT, you may see some validation warnings: you can safely ignore them.

Preparing and sending patches

When you decide to send us your new patch, you'll need:

  • an Eclipse account (you can create it [https://accounts.eclipse.org/user/register here])
  • to sign the [https://www.eclipse.org/contribute/cla Eclipse Contributor Agreement]

Patches must be sent via GitHub pull requests: https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/about-pull-requests

Before sending patches, you should file a bug report.

The commit message must be like this:

  Bug #1234 - Description
  
  Notes

Where:

  • #1234
    is the GitHub issue
  • Description
    is the main title of the patch.
  • Notes
    are optional notes about the patch.

Compiling PDT outside Eclipse

You can compile the PDT source code outside Eclipse.

First of all, you need to clone the PDT git repository:

git clone https://github.com/eclipse-pdt/pdt

If you are an Eclipse user and/or a PDT committer:

git clone [email protected]:eclipse-pdt/pdt.git

To build PDT, you need Maven, and launch these commands:

# project root dir
cd org.eclipse.pdt
# build and run all tests
mvn clean verify
# build and ignore all tests
mvn clean verify -DskipTests
# build and skip performance tests only (recommend)
mvn clean verify -DskipPdtPerformanceTests

To build the PDT release:

# project root dir
cd org.elipse.pdt
# this will produce normalized, signed and packed release, inside eclipse.org infrastructure
mvn clean verify -Prelease
#this will produce normalized and packed release
mvn clean verify -Prelease -DskipSign

Sonar

Sonar is used in order to track Code Quality:

Developer Resources

After setting up PDT source code please have a look at a set of docs we have for our developers on the Developer Resources page.

Update help pages

All help pages sitting under plugins/org.eclipse.php.help/docs/source/ in *.md format.

While make verify, our build system converting it to *.html files in exactly same structure and also:

  • Remove ###- part from each *.md file, and fix all internal links.
  • Regenerate IPHPHelpContextIds interface
  • Build helpContexts.xml file
  • Build toc.xml file

Which editor should I use?

You can work with any markdown editor, but because our build system use Mylyn Wikitext, you should install wikitext editor from https://eclipse.org/mylyn/downloads/ to be sure that everything is ok.

Howto register new help context id?

Add this code to markdown file:

<!--context:your_context_id-->
