# replacement patterns
# ######################################################################################################################################################
# replacement patterns can be string, or pathlib.Path Objects - the pathlib Objects can be absolute or relative
# if You chain such pathlib Objects in template files or directories,, the final destination of the file might be not were You expected.
# since You might pass relative or absolute paths to the PizzaCutter CLI Application, You should be careful
# about the resulting paths, especially if You pass absolute paths.
# beware of differences in Linux and Windows : on Windows pathlib.Path('/test') is relative, on Linux it is absolute !
# best practice is to use relative paths in the form pathlib.Path('./test')
# with great flexibility there comes big responsibility. You should test Your Pizzacutter conf_files with absolute and relative Paths
# for the project path, and check carefully the result. We might disallow absolute paths in the future, or only enable it with a flag,
# not to allow dangerous Pizzacutter conf_files to overwrite system files.
# in general, if not really needed on purpose, we would suggest to use only string replacements in directory- and filenames.
# on the other hand, this feature can be very useful, in order t drop files to the user desktop,
# user home, windows appdir, etc... OUTSIDE of the Project Path given
# path replacement patterns are also valid in text files
# in that case the pattern will be replaced with the content of that file (if found)
# if the file is not found, or not readable, the string of the path will be filled in. (with a warning)
# You can even include Files from outside the template Folder, or from the Project Folder itself.
# Those replacements will be done AFTER the template Files are copied to the target Project, to make sure that even
# replacements from the target project file work properly.
# this can be useful for situations like:
# /template_folder/my_special_configuration{{PizzaCutter.option.no_overwrite}}.txt # template for the special configuration
# /template_folder/some_file.txt # that file includes /project_folder/my_special_configuration.txt
# in that case, /project_folder/some_file.txt will include /project_folder/my_special_configuration.txt correctly,
# even if the project is just created.
# chaining of only relative Paths :
# {{PizzaCutter.relative_path_object1}} = pathlib.Path('test1/test2') # relative path
# {{PizzaCutter.relative_path_object2}} = pathlib.Path('test3/test4') # relative path
# .../template_directory/{{PizzaCutter.relative_path_object1}}/{{PizzaCutter.relative_path_object2}}/test.txt will work as expected. and resolve to:
# .../template_directory/test1/test2/test3/test4/test.txt --> .../project_directory/test1/test2/test3/test4/test.txt
# chaining of Absolute and Relative Paths :
# {{PizzaCutter.absolute_path_object1}} = pathlib.Path('/test1/test2') # absolute Path
# {{PizzaCutter.relative_path_object2}} = pathlib.Path('test3/test4') # relative path
# .../template_directory/{{PizzaCutter.absolute_path_object1}}/{{PizzaCutter.relative_path_object2}}/test.txt will work as expected. and resolve to:
# /test1/test2/test3/test4/test.txt
# by that way You might even write configuration files into /usr/etc or similar (depending on Your rights)!
# unexpected Result when chaining Absolute and Relative Paths in the wrong order :
# {{PizzaCutter.relative_path_object1}} = pathlib.Path('test1/test2') # relative Path
