GDSL Awesomeness – Advanced Example showing domain properties implementation

24 / Sep / 2012 by Kushal Likhi 0 comments

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)

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 =~ ".*/*grails-app/mongoDomain/.*") {

        classType?.fields?.each {
            if ((it.name == "belongsTo") || (it.name == "hasOne")) {
                it.children.each {child ->
                    List definitions = child.text.toString().replaceAll(/\[|\]/, "").trim().tokenize(",")*.trim()
                    definitions.each {
                        List tokens = it.tokenize(":")*.trim()
                        property(name: tokens.first().toString(), type: tokens.last().toString())
                    }
                }
            }
        }

        classType?.fields?.each {
            if (it.name == "hasMany") {
                it.children.each {child ->
                    List definitions = child.text.toString().replaceAll(/\[|\]/, "").trim().tokenize(",")*.trim()
                    definitions.each {
                        List tokens = it.tokenize(":")*.trim()
                        property(name: tokens.first().toString(), type: "List<${tokens.last().toString()}>")
                    }
                }
            }
        }

        //Adding Properties
        property(name: "id", type: 'org.bson.types.ObjectId')
        property(name: "mongoVersion", type: 'Integer')
        property(name: "version", type: 'Integer')
        property(name: "log", type: 'org.apache.log4j.Logger')
        property(name: "clazz", type: 'Class')
        property(name: 'errors', type: 'Map')

    }
}
