HOWTO: Exclude patterns for folders - an overiew

[goebbe]

Exclude patterns for folders / directories can be puzzling at first.

The following examples show how to exclude folders in Vykar, for the most common cases.
You can cherry-pick rules from the list and adapt them to your liking.

exclude_patterns:
  ### Examples for excluding folders ### 
  ## a) Include the folder but exclude its content (and all subfolders): 
  - '/testfolder/*'         # exclude content,      matches only first level - by explicit path
  - '*/testfolder/*'        # exclude content,      matches only second level
  - '*/*/testfolder/*'      # exclude content,      matches only third level
  - '/test1/testfolder/*'   # exclude content,      matches by explicit path
  - '/**/testfolder/*'      # exclude content,      matches everywhere 
  - 'test1/**/testfolder/*' # exclude content,      matches everywhere - if "test1" is further up the path
  - 'testfolder/*'          # exclude content,      matches only first level    EXCEPTION!  

  ## b) Exclude folders entirely:
  - '/testfolder/'          # exclude folder,       matches only first level - by explicit path
  - '*/testfolder/'         # exclude folders,      matches only second level 
  - '*/*/testfolder/'       # exclude folders,      matches only third  level 
  - '/test1/testfolder/'    # exclude folder,       matches by explicit path
  - '/**/testfolder/'       # exclude folders,      matches everywhere
  - 'test1/**/testfolder/'  # exclude folders,      matches everywhere - if "test1" is further up the path
  - 'testfolder/'           # exclude folders,      matches everywhere          EXCEPTION! 

  ## Attention if there is no trailing "/":
  - '**test'                # exclude folders AND files  matches everywhere

Note that for the most part the exclude_patterns: for folders are "as expected".
However, there is one exception to this rule, that I have commented accordingly.

Hope this is helpful.
