Hi folks,

I have been using nano to edit my pyFoam scripts and I wanted to use an IDE for the script edition because the python console would help me a lot to test the functions while programming the code.

So I loaded my code in Spyder, however, I was getting an error related to importing the pyFoam modules when running the code.

[autoreload of PyFoam.Infrastructure.Configuration failed: Traceback (most recent call last):
  File "C:\Users\Felix\anaconda3\lib\site-packages\IPython\extensions\autoreload.py", line 245, in check
    superreload(m, reload, self.old_objects)

]

As I saw in this post the error is related to the use of backslashes in python vs. windows. A classical error as I learned somewhere else.

And as it can be seen, when evaluating the userDirectory and globalDirectory variables contained in the File "C:\Users\Felix\anaconda3\lib\site-packages\PyFoam\Infrastructure\Configuration.py", there are indeed slashes and backslashes mixed.

In[43]: userDirectory()
Out[43]: 'C:\\Users\\username\\.pyFoam'
In[44]: globalDirectory()
Out[44]: '/etc\\pyFoam'

What I did to solve the problem was to replace the "" with "/" in the variables using the .replace('\\','/') function. The caseBuilder line in the Configuration.py file then became:

"CaseBuilder":{
        "descriptionPath": eval('["'+path.curdir+'","'+path.join(userDirectory().replace('\\','/'),"caseBuilderDescriptions")+'","'+path.join(globalDirectory().replace('\\','/'),"caseBuilderDescriptions")+'"]'),
    },

Which solved the problem and the modules were loaded perfectly after. Then I could use every pyFoam modules and functions in Spyder.
