ONCE UPON A TIME…„Based on a true story…“

That guy had a smart idea how to make Eclipse even better…

Thanks to Eike Stepper for permission to reuse his portraits :-)

…he created an extension point…

How can I read all extensions known to the

system?

Hey, this was done so many times before. It should be easy to find an example…

I GIVE UP!

But indeed there is an example…

IExtensionRegistry registry = Platform.getExtensionRegistry();IExtensionPoint point = registry.getExtensionPoint(EXT_POINT_ID);!for (IExtension ext : point.getExtensions()) { for (IConfigurationElement elem : ext.getConfigurationElements()) { MyProvider provider = elem.createExecutableExtension(CLASS_ATTR); res.add(provider); }}return res;

Hmm, if creating own snippets is so simple, why not

share them with others?

Cool stuff!What’s planned for 2.2?

Snipmatch 2.2 Roadmap for SR1• Class-path dependent snippet proposals:

• No SWT on your class-path? => No SWT snippets.

• Xtext based snippet editor: • with syntax highlighting, code completion,error detection.

(preview demo’ed)

• Multiple repositories: • Gerrit, git, file, db, …

• General snippet goodness: • Create snippets from text selection. • Voting and commenting on snippets (SR2 maybe).

• Many more (crowdsourced and mined) snippets!22

Get ready for Eclipse Luna!

!void ctor() {! List l = new A…}

Crowdsourcing constructor completion

33

What is the mostly likely completion a developer looks for in this particular situation ?

!void ctor() {! List l = new A…}

Use (costly) subtype checks

!void quickfix() {! List l = new A}

How about fixing quick-fix?

36Not fixed yet. But could be easily - when you start sharing your knowledge…
