Source code: Lib/binhex.py
This module encodes and decodes files in binhex4 format, a format allowing representation of Macintosh files in ASCII. Only the data fork is handled.
binhex module defines the following functions:
Convert a binary file with filename input to binhex file output. The output parameter can either be a filename or a file-like object (any object supporting a
Decode a binhex file input. input may be a filename or a file-like object supporting
close()methods. The resulting file is written to a file named output, unless the argument is
Nonein which case the output filename is read from the binhex file.
The following exception is also defined:
Exception raised when something can’t be encoded using the binhex format (for example, a filename is too long to fit in the filename field), or when input is not properly encoded binhex data.
Support module containing ASCII-to-binary and binary-to-ASCII conversions.
There is an alternative, more powerful interface to the coder and decoder, see the source for details.
If you code or decode textfiles on non-Macintosh platforms they will still use the old Macintosh newline convention (carriage-return as end of line).
