[IPython-user] Various questions re: IPython on Windows

[Robin Siebler]

I'm having a few problems and I don't know if these are bugs, or simply
user error.  Any help would be appreciated.  :)


1.  When I try to run the %edit command, I always get the below error. 
The error occurs *before* my editor has even launched!

Editing... done. Executing edited code...
Could not open file
<c:\docume~1\rsiebler\locals~1\temp\ipython_edit_zo5me2.py>
for safe execution.
WARNING: File not found. Did you forget to save?

2.  When I try to use the %run command on a script, I always get this error:

In [3]: %run save_song_list.py
---------------------------------------------------------------------------

c:\temp\save_song_list.py in main()
     50         last_song = db['last_song']
     51         if song in last_song:
---> 52             sys.exit()
     53         else:
     54             if len(last_song) == 3:

SystemExit:

    962         else:
    963             magic_args = self.var_expand(magic_args,1)
--> 964             return fn(magic_args)
    965
    966     def ipalias(self,arg_s):

ner)
   1679             if restore_main:
   1680                 sys.modules['__main__'] = restore_main
-> 1681             self.shell.reloadhist()
   1682
   1683         return stats

C:\Python\Lib\site-packages\IPython\iplib.py in reloadhist(self)
   1262
   1263         if self.has_readline:
-> 1264             self.readline.clear_history()
   1265             self.readline.read_history_file(self.shell.histfile)
   1266

AttributeError: 'module' object has no attribute 'clear_history'

3.  For pysh, if I try to use $var=cmd or $$var=cmd as shown in the docs,
I get the following error:

[Documents and Settings\rsiebler]|15> $foo = !dir
-----------------------------------------------------
   File "<ipython console>", line 1
     $foo = !dir
     ^
SyntaxError: invalid syntax
