Custom transformers reading workspace name

Question

I want to include the workspace name as part of some metadata I generate

Running the workbench as a workspace the $(FME_MF_NAME) variable returns my workspace name Once I convert it to a custom transformer (CT) this variable returns the fmx name rather than the calling fmw name

I set a published parameter to the value of the $(FME_MF_NAME) in the CT

Running as a Linked CT I get the following error

Starting translation...

Undefined macro `ArcGIS_MetaItemDescription_FME_MF_NAME' dereferenced in file `C:\\Users\\scooter\\Documents\\FME\\Transformers\\ArcGIS_MetaItemDescription.fmx'

Program Terminating

Translation FAILED.

Running as an embedded CT I get the correct result

When I embed and run it using a private parameter I get the same error

Starting translation...

Undefined macro `ArcGIS_MetaItemDescription_FME_MF_NAME' dereferenced in file `C:\\Users\\scooter\\Documents\\My FME Workspaces\\wb-xlate-1399417605939_8048'

Program Terminating

Translation FAILED.

I really would prefer to use this as a linked CT using a private parameter

Pretty inexperienced in terms fsuing CT and passing parameters so hoping someone can help

Thanks

Hi,

not sure this is doable since the .fmx basically is like its own workspace (if my understanding is correct).

However, I suggest you use the following snippet in a PythonCaller inside your custom transformer to dump all available macro values to see if any of them fits your needs:

-----

import fmeobjects

import pprint

def showAllMacroValues(feature):

pp = pprint.PrettyPrinter(indent=4)

pp.pprint(FME_MacroValues)

Hi David,That exposed a master name that i could use to get the job done. THanks for your help

feature.setAttribute("_metaWorkbench", FME_MacroValuesu'FME_MF_NAME_MASTER'])

cheers
