22 This module has a similar scope to os.path, containing utility
23 functions for dealing with paths in Blender.
31 "display_name_from_filepath",
43 def abspath(path, start=None, library=None):
45 Returns the absolute path relative to the current blend file
46 using the "//" prefix.
48 :arg start: Relative to this path,
49 when not set the current filename is used.
51 :arg library: The library this path is from. This is only included for
52 convenience, when the library is not None its path replaces *start*.

71 when not set the current filename is used.

84 Returns true if *path* in a subdirectory of *directory*.
85 Both paths must be absolute.

95 Returns a name with characters replaced that
96 may cause problems under various circumstances,
97 such as writing to a file.
98 All characters besides A-Z/a-z, 0-9 are replaced with "_"
99 or the replace argument if defined.
