Create Fixed-Width Files Easily

If you need to create fixed-width files, you may be interested in a fixed-width recordset builder I wrote for Groovy. It lets you create a set of fixed-width records with the following sort of code:

def builder = new FixedWidthRecordSetBuilder()
builder.TestData(){
  record1(){
    field1(startPosition : 0, width : 5, content : short_content)
    field2(startPosition : 5, width : 10, content : long_content)
  }
  record2(){
    field1(startPosition : 0, width : 5, content : short_content.reverse())
    field2(startPosition : 5, width : 10, content : long_content.reverse())
  }
}

builder.records.each { record ->
 println record.formattedContent  //or to a file
}

You can get the goods from my svn repository:

The Groovy website has more on the general topic of builders in Groovy.

Enjoy!
