UseCases.FileSysObjects.createAndUseSearchLists.from_literal.CallCase module

Create a plist, find a matching relative filepathname in directory tree.

class UseCases.FileSysObjects.createAndUseSearchLists.from_literal.CallCase.UseCase(methodName='runTest')

Bases: unittest.case.TestCase

testCase000()

The scope of the start node is literal(L).

Calling elementary functions.

• Data:

  see 'testdata.examples'
  

  refer also to the manual [filesystem-elements-as-objects]

• Call:

  import testdata
  import filesysobjects.FileSysObjects
    
  # start of upward search - file is converted into it's containing directory node
  s = os.sep
  any_sub_path = os.path.normpath('examples/a/b0/c/a/b0/c/F')
  spath  = testdata.mypath
  spath += any_sub_path
  
  # Here an empty list is used for search only. The function adds 
  # entries to the provided list storage, thus e.g. to 'sys.path' too.
  _plist = []
  
  # 0. build a search path list - if not yet available
  #    adds each directory from spath to its matching 
  #    subnode  "a/b"
  #
  setUpperTreeSearchPath(spath,os.path.normpath('a/b0'), _plist)
  
  # 1. make it canonical - optional, here just a demo
  clearPath(_plist,**{'redundant':True,'shrink':True}) # and clear them immediately
  
  # 2.a. find the requested entry
  rp = findRelPathInSearchPath("F[0-5]*",_plist)
  
  # 2.b. find the requested entry - here as demo with a relative path
  rp = findRelPathInSearchPath("c/*/b0/F[0-5]*",_plist)
  

• Result:

  expected = os.path.normpath(testdata.mypath+'/examples/a/b0/c/a/b0/F1')
