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 […]
As we all know that groovy is a dynamic programming language, so we can add any method to any class at runtime. First, let’s see a small and simple example of metaProgamming given below, in which we are adding a method (isEvent) into an Integer class. [groovy] Integer.metaClass.isEven = { -> // only (->) sign […]

It is normally difficult to copy file/folders from one location to another. In my recent Grails Development project, i successfully achieved this. I had to copy files/folders from one location to another on file system. I searched about it and came across a cool method to copy files or directories from one location to another. We […]
