hi, Very often we use delegates in our closure calls. It would be great if we could get code-hinting in the closure via the delegates. Now let us take a very simple scenario, where we made a method “with” which delegates the delegate objet to closure and runs it. [java] class Delegator { […]
hi, Sometimes we need to add specific methods in the closures which are passed to methods with a particular name. This can be simply done as follows Suppose we need to add the method named “setHeaders(Map headers)” in all closures passed to method with name “withREST” [java] //Get the context for all closures […]
hi, Sometimes we need to add specific properties in the closures which are passed to methods with a particular name. This can be simply done as follows Suppose we need to add the property named requestMethod of type String in all closures passed to method with name “withREST” [java] //Get the context for […]
hi, If we want to contribute to classes which matches a particular path/name pattern, then we can use PSI Class patterns to do it. the code is as follows: [java] import com.intellij.patterns.PsiJavaPatterns import com.intellij.patterns.PlatformPatterns //get the context of all files, and enable path matching. Note: Don’t change anything in context here. def ctx […]
Hi, Sometimes we need to contribute dynamically using current target class type. Lets take the example of .get() and .list() methods of Grails domain class. The signature of each method is as follows: public <DomainClassType> get(Long id) , Example: DemoClass.get(1) will return an object of “DemoClass” public List<DomainClassType> list() The GDSL Script […]
Hi, I have been using the Grails mail plugin for a while now, this plugin injects a method named “sendMail” to all controllers and services. Our aim will be to provide auto-completes for this method and the closure inside. The GDSL Script is as follows: [java] import com.intellij.patterns.PsiJavaPatterns import com.intellij.patterns.PlatformPatterns //Let Us […]
Hi, Here i will illustrate how you can get the code of a method within GDSL Script: The script is as follows: [java] import com.intellij.patterns.PsiJavaPatterns import com.intellij.patterns.PlatformPatterns def mongoContext = context( ctype: PsiJavaPatterns.psiClass().withName(PlatformPatterns.string().matches(/.*/)) ) contributor(mongoContext) { def path = "" try { path = psiClass.containingFile.originalFile.virtualFile.path } catch (Exception e) { } if (path […]
Hi, Here is an example which uses a lot of gdsl concepts. This example tries to simulate injecting properties to Domains. The Example is as follows: (The code is self explanatory and can be used as a reference) [java] import com.intellij.patterns.PsiJavaPatterns import com.intellij.patterns.PlatformPatterns def mongoContext = context( ctype: PsiJavaPatterns.psiClass().withName(PlatformPatterns.string().matches(/.*/)) ) contributor(mongoContext) { def […]
Hi, In the previous post, we saw how to Retweet any user’s tweet from our application. In the same project, i needed to post a new tweet on behalf of the authenticating user from the application using Twitter API. Posting a new status update is quite easy using Twitter4j library. For making any twitter API […]
