#170 pyFoamCompareDictionary.py option --not-equal

[code-red]

The --not-equal option of pyFoamCompareDictionary seems to be without effect. The output of pyFoamCompareDictionary is identical in these cases:

* I compare the the same dictionary of two different cases

ΠpyFoamCompareDictionary.py case01/system/fvSolution case02/system/fvSolution
ΠpyFoamCompareDictionary.py case01/system/fvSolution case02/system/fvSolution --not-equal

* I compare different dictionaries ot two different cases

ΠpyFoamCompareDictionary.py case01/system/fvSchemes case02/system/fvSolution
ΠpyFoamCompareDictionary.py case01/system/fvSchemes case02/system/fvSolution --not-equal

* Only, omitting the name of the second dictionary and passing the option leads to an error

ΠpyFoamCompareDictionary.py case01/system/fvSolution case02/ --not-equal

Is this the intended behaviour of this option?

Sorry, I forgot to add my pyFoam version: 0.5.7

What is the behaviour that you're expecting?

To quote from the online help
{{{
--not-equalŒŒŒŒŒŒŒŒŒŒŒŒ Allow source and destination to have different names
}}}
It says ALLOW, not REQUIRE

Usual behaviour of the utlitiy is to only compare a fvSolution to a fvSolution (it will complain if the names are not the same). That switch allows you to compare a fvSolution to a fvSolution.safe. The disadvantage is that it will no longer look for the "soulmate" automagically. That was the error you were seeing.

If you have a suggestion to the wording of the online help that explains it better (but still briefly): Please

If I compare different dictionaries of two different cases

ΠpyFoamCompareDictionary.py case01/system/fvSchemes case02/system/fvSolution
ΠpyFoamCompareDictionary.py case01/system/fvSchemes case02/system/fvSolution --not-equal

then the output is exactly the same, whether I allow different names or not.

I expected some kind of warning message. However, maybe stating the filename of the second dictionary overrides the assumption of equal filenames.

By the way, I like the expression automagical.
