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). |
---|
10 | |
---|
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. |
