Hi Jochen and all,
so a while ago my groovy script grew (big enough) and I had to split it
into multiple classes. But I wanted my users to still be able to run it
with a simple command (e.g. ./TagText.groovy on Linux and groovy
TagText.groovy on Windows).
So now all my scripts have a wrapper, example of one of them is below - the
main script was called TagText.groovy and now the main functionality moved
to TagTextCore.groovy.
This works, but I had to add such a wrapper to all scripts like that. And I
feel that this type of code does not belong in the apps - this is
system-level functionality.
Regards,
Andriy
@CompileStatic
class TagText {
@groovy.transform.SourceURI
static URI SOURCE_URI
static String SCRIPT_DIR=new File(SOURCE_URI).parent
static void main(String[] args) {
long tm1 = System.currentTimeMillis()
def cl = new GroovyClassLoader()
cl.addClasspath(SCRIPT_DIR + "/../../../../")
def resourceDir = SCRIPT_DIR + "/../../../../../resources"
if( ! new File(resourceDir).isDirectory() ) {
new File(resourceDir).mkdirs()
}
cl.addClasspath(resourceDir)
def basePkg = TagText.class.getPackageName()
def tagTextClass = cl.loadClass("${basePkg}.tag.TagTextCore")
def m = tagTextClass.getMethod("main", String[].class)
def mArgs = [args].toArray() // new Object[]{args} - Eclipse chokes on this
m.invoke(null, mArgs)
}
}
