PTools::SDF::TAG

If you're in need of a Python module that can implement a Simple Data File in "Tagged Data" format, PTools::SDF::TAG is one such option - and it comes with a range of useful features. After adding the module to your project via "use PTools::SDF::TAG", you can use the new PTools::SDF::TAG("$fileName") to create a new object using a specified file. This will allow you to access and set data field values with ease - simply use "$dataValue = $tagObj->param("fieldName")" to read the contents of a field, or "$tagObj->param("fieldName", "new value")" to make changes. As well as data fields, you can use PTools::SDF::TAG to access and set control field values with ease by using "$ctrlValue = $tagObj->ctrl("fieldName")" and "$ctrlValue = $tagObj->ctrl("ctrlField", "new value")".

To make configuration easier, PTools::SDF::TAG allows you to determine the current field names contained in the $tagObj object. "@fields" will enable you to see the list of fields, while "$fields = $tagObj->ctrl("dataFields")" lets you assign this list to another variable. Meanwhile, "$tagObj->ctrl("fileName", "data/control.tmp")" will let you change the filename of the data and control files respectively, and "$tagObj->ctrl("dataFields","folder:seqnbr")" will enable you to set the field names.

Once you're happy with your changes, you can save them using "$tagObj->save". Overall, PTools::SDF::TAG is a comprehensive Python module that makes working with Simple Data Files in "Tagged Data" format a breeze.
