Groovy Log Splitter

Matt and Blaine are having fun writing Ruby log splitters. I couldn’t pass up the opportunity to write one in Groovy, so here it is:

baseFilename = args.size() > 0 ? args[0] : "split.log"   maxLines = args.size() == 2 ? args[1] : 500000   fileCount = 0   lineCount = 0   inputFile = new File(baseFilename)   writer = newWriter(baseFilename)   inputFile.eachLine {     if (lineCount >= maxLines) {       writer = newWriter(baseFilename)     }     writer.append("${it}\n")     lineCount++   }      def newWriter(filename) {     lineCount = 0     new File("${fileCount++}_${filename}")   }

Extraneous Period in Groovy println

Update: Looks like it’s a problem in GroovyTestCase. testXXX() method always outputs a “.”

Update: Ah. It’s JUnit’s text-based test runner that is the culprit. Guess I shouldn’t exclusively use the GUI runner.

GROOVY-1463.

Running this test:

class PrintlnTest extends GroovyTestCase {
  void testSomething() {
    def name = GroovyTestCase.class.simpleName
    assertEquals(GroovyTestCase.class.simpleName, name)
    assertTrue(name.length() == "GroovyTestCase".length())
    println name
    println name
  }
}

produces this output:

.GroovyTestCase
GroovyTestCase

Time: 0

OK (1 test)

Anyone have a clue?
