     3 OVERVIEW

     4 

     5 icopen patches MacOS Python to use the Internet Config file mappings to select

     6 the type and creator for a file.

     7 

     8 Version 1 released to the public domain 3 November 1999

     9 by Oliver Steele (steele@cs.brandeis.edu).

    11 DETAILS

    12 

    13 This patch causes files created by Python's open(filename, 'w') command (and

    14 by functions and scripts that call it) to set the type and creator of the file

    15 to the type and creator associated with filename's extension (the

    16 portion of the filename after the last period), according to Internet Config.

    17 Thus, a script that creates a file foo.html will create one that opens in whatever

    18 browser you've set to handle *.html files, and so on.

    19 

    20 Python IDE uses its own algorithm to select the type and creator for saved

    21 editor windows, so this patch won't effect their types.

    22 

    23 As of System 8.6 at least, Internet Config is built into the system, and the

    24 file mappings are accessed from the Advanced pane of the Internet control

    25 panel.  User Mode (in the Edit menu) needs to be set to Advanced in order to

    26 access this pane.

    27 

    28 INSTALLATION

    29 

    30 Put this file in your Python path, and create a file named {Python}:sitecustomize.py

    31 that contains:

    32         import icopen

    33 

    34 (If {Python}:sitecustomizer.py already exists, just add the 'import' line to it.)

    35 

    36 The next time you launch PythonInterpreter or Python IDE, the patch will take

    37 effect.
