We were keeping this incase people somehow were still using old configs that had the directed setting.

[tristan-f-r]

We already broke old configs in #292. SPRAS is also not stable software.

Now if I provide an old config file I get

TypeError in file "C:\Users\agitter\Desktop\madison\collaborators\Ritz\spras\Snakefile", line 21:
'bool' object is not iterable
  File "C:\Users\agitter\Desktop\madison\collaborators\Ritz\spras\Snakefile", line 21, in <module>
  File "C:\Users\agitter\Desktop\madison\collaborators\Ritz\spras\spras\config\config.py", line 35, in init_global
  File "C:\Users\agitter\Desktop\madison\collaborators\Ritz\spras\spras\config\config.py", line 114, in __init__
  File "C:\Users\agitter\Desktop\madison\collaborators\Ritz\spras\spras\config\config.py", line 313, in process_config
  File "C:\Users\agitter\Desktop\madison\collaborators\Ritz\spras\spras\config\config.py", line 186, in process_algorithms

Previously I would get

C:\Users\agitter\Desktop\madison\collaborators\Ritz\spras\spras\config\config.py:316: UserWarning: UPDATE: we no longer use the directed key in the config file
  self.process_algorithms(raw_config)

and the workflow would run.

I agree we don't want to be too tethered to backwards compatibility, but the unintelligible error message is much worse than the user-friendly warning.

[tristan-f-r]

I am always in favor of better error messages (including in this case), and we can (and do!) provide better error messages in general with #321, since we'll know in advance what algorithms support what keys.

I agree we don't want to be too tethered to backwards compatibility, but the unintelligible error message is much worse than the user-friendly warning.

Especially since we currently get this with any typo of algorithm parameters.

[agitter]

If #329 will solve the general case, I would wait to merge this until that is ready.

[tristan-f-r]

#329 removes directed anyway.
