If a User Parameter ends in a backslash - such as a Windows path, then accessing that value in a PythonCaller results in extra text. Example: if a User Parameter called foldername has the value:
frog\\
then using fme.macroValues['foldername'] or FME_MacroValues['foldername'] in a PythonCaller returns:
frog GUI OPTIONAL TEXT foldername Folder name:
I got the same issue. It just changes to the 'frog\\' to that whole string. I am curious about the how and why?
+6Hello @rsliva and @jneujens
Are you able to provide us with a few more details:
What is the User parameter definition?
Along with the PythonCaller code, you are running to see the results. This appears to be a possible bug and as such, I would file a PR once I verify the behaviour.

This is my example workspace, just something really quick to check @rsliva's question.

I have found an existing PR pertaining to this, I have attached this posting to the PR, so that if any updates occur regarding a possible fix this question will be updated.
In the meantime, if dealing with a string that ends with a \\, it may be best to try another Parameter type such as 'Folder' or 'File Name'.
I hope this helps.
I just stumbled upon this old thread, I'll just add the following for those that are still affected by this issue.
Rather than writing:
fme.macroValues['foldername']You can write the following, which should prevent FME from interfering with your code:
fme.macroValues.get('foldername')
