FME - Is it possible to add custom command line input arguments to a workspace?

Question

I have a workspace whose command line call is like so:

fme.exe DwgImporter.fmw
          --SourceDataset_ACAD Z:\FME\Data\DWGs\*.dwg
          --DestDataset_MSSQL_ADO IHS_TPW
          --SourceDataset_GEODATABASE_SDE sde

Is it possible to somehow add my own custom input arguments that can then be read from within the workflow? Something like:

fme.exe DwgImporter.fmw
          --SourceDataset_ACAD Z:\FME\Data\DWGs\*.dwg
          --DestDataset_MSSQL_ADO IHS_TPW
          --SourceDataset_GEODATABASE_SDE sde
          --CustomArg1 arg1
          --CustomArg2 arg2

Or does anyone know of another way to pass in variables at runtime?

Answer 1

ParameterFetcher

Answer 2

More generally, you need what is called a "published parameter" -- you don't have to use the ParameterFetcher to pull them out in a workflow either. This FAQ http://www.fmepedia.com/index.php/Can_I_pass_a_variable_to_FME_to_replace_a_fixed_value_within_a_workspace describes what I'm talking about very concisely, and if you grab section 4 of the online FME self study course at http://www.safe.com/support/onlinelearning/selfstudy.php, on page 4-24 and 4-25 these are explained more as well.

Hope this helps.
