| # AstBuilder and AST Transformation Example |
| |
| This example shows how to use the AstBuilder to add a public static void main(String[]) |
| method to a class. |
| |
| The example requires ant in your path and the Groovy 1.7 (or greater) |
| installed on your system. |
| |
| Prior to running, __build.xml__ needs to be configured to reference the |
| installed version of groovy. The following must be done: |
| |
| 1) Set _groovy.version_ to the version of groovy installed. |
| 2) Update _groovy.home_ to point to the location where groovy is installed. |
| |
| Once these updates are made and saved, the build file is ready to use. |
| |
| To build the example run "ant" from the current directory. The default |
| target will compile the classes needed. The last step of the build |
| script prints out the command needed to run the example. |
| |
| To run the example perform either of the following from the command lines: |
| groovy MainExample.groovy |
| groovyc MainExample.groovy (and then invoke with java or view with javap) |
| |
| The example should print: |
| Hello from the greet() method! |
| |
| No exceptions should occur. |
| |
| The MainIntegrationTest.groovy file shows how to invoke an ASTTransformation |
| from a unit test. An IDE should be able to debug this. |
