Error with nested else statement, InvalidPython

[supermaxiste]

Hi,

I was trying to run a --check on my Snakemake workflow and I got a parsing error related to a nested else statement. This issue might be similar to #91.

For my Snakefile I get the following error:

[ERROR] In file "Snakefile":  'InvalidPython: Got error:
'''
Cannot parse: 1:0: else:
'''
while formatting code with black.'

This parsing error doesn't appear when I comment this else statement in my code:

if len(config) == 0:
	if os.path.isfile("./config.yaml"):
		configfile: "./config.yaml"
	#else:
		#sys.exit(f"Make sure there is a config.yaml file in {os.getcwd()} or specify one with the --configfile commandline parameter.")

Thanks @supermaxiste , this was indeed a bug, and I made a fix in branch fix_96. It now parses your Snakefile without error. We'll look to release a new version on PyPI soon, else you could try installing from source from branch fix_96 and let us know if all OK!

Hi @bricoletc,

just checked the branch and tried a run on my Snakefile, no parsing errors.

Thank you and feel free to close the issue anytime.
