issues installing readine-1.12 on WinXP

[Michele Simionato]

I have installed Gary Bishop's readline library and Thomas
Heller's cypes; I have Python 2.4 ActiveState distribution.
When I try to import readline I get the following error:

C:\Programmi>python
ActivePython 2.4 Build 243 (ActiveState Corp.) based on

Any hints on what is causing this and the cure?
TIA,

That shouldn't happen AFAICT. Check line 108 in keysyms.py and make
sure it says "vk = VkKeyScan(ord(char))".

 

[Michele Simionato]

That line seems right. The function is

def char_to_keyinfo(char, control=False, meta=False, shift=False):
vk = VkKeyScan(ord(char))
if vk & 0xffff == 0xffff:
print 'VkKeyScan("%s") = %x' % (char, vk)
raise ValueError, 'bad key'
if vk & 0x100:
shift = True
if vk & 0x200:
control = True
if vk & 0x400:
meta = True
return (control, meta, shift, vk & 0xff)

Maybe the problem is related to the fact that I am using the Italian
keyboard?

 

[Simon Percivall]

Possibly. Is the ` sign available as an unmodified key?

 

[Michele Simionato]

No, I don't even know how to get it under Windows (usually I use
Linux). Switching to the US keyboard
does not help, anyway. I get the same error.

[Simon Percivall]

Well, just modify the source in that case.

 

[Michele Simionato]

Well, this is ugly as the sin but it seems to work, at least for the
moment:

vk = VkKeyScan(ord(char))
if vk == -1: # ugly fix for backtips
vk = 96

I will write to Gary Bishop to point out this issue with the Italian
keyboard and see if he has some decent
solution.
