Subject: [Ironpython-users] issue with chardtect.detect with unicode type
Message-ID: <BLU184-W77D4AAABF02730F73044A0A2B30@phx.gbl>

Hi All,
 
I'm playing with request but running into an issue with chardet.detect call. 
 
def detect(aBuf):
    if ((version_info < (3, 0) and isinstance(aBuf, unicode)) or
            (version_info >= (3, 0) and not isinstance(aBuf, bytes))):
        raise ValueError('Expected a bytes object, not a unicode object')
    from . import universaldetector
    u = universaldetector.UniversalDetector()
    u.reset()
    u.feed(aBuf)
    u.close()
    return u.result
 
It always throws ValueError exception 'Expected a bytes object, not a unicode object'.  The problem is the isinstance(aBuff,unicode) which returns True for IronPython and not CPython.  I guess in IronPython strings are both a str and unicode types
 
>>> v = 'value'
>>> isinstance(v,unicode)
True
>>> isinstance(v,str)
True
 
 
I was wondering if this is expected behavior for IronPython? At the moment I just removed this check in my local copy so I get pass this issue with requests. 

Thanks.

Yes, the unicode type in IronPython is is the same as string by design,

?unicode == str?  will return True

Subject: [Ironpython-users] numpy dot net ndarray interface
Message-ID: <212D925E4ED2844F900023F8D64870964A226677@AMSPRD9002MB042.MGDPHG.emi.philips.com>

Hi all,
I have succeeded in compiling the old numpy and scipy refactor projects and actually calling from a C# VS project. I am stuck at how the numpy ndarray array converts to a C# type. I tried IList<double> but I got the error that it got an ndarray. But there is no ndarray C# type so what do I use?

Cheers,
Sven

Subject: [Ironpython-users] Error installing package with pip
Message-ID: <557872DB.9030504@ccc.com.uy>

Hello everyone,
I posted this on github and got no answers, I found a similar posting 
here from January 
(https://mail.python.org/pipermail/ironpython-users/2015-January/017391.html) 
where no solution is mentioned so here I am.
I get an error when I try to install a package via pip.
I use ironpython 2.7.5 and tested on several PC, all windows.



Copied from https://github.com/IronLanguages/main/issues/1203

I'm new to Python so this might be something I'm doing wrong, but I'm 
having the following problem:
I installed iron Python 2.7.5, and then installed pip with|ipy.exe 
-X:Frames -m ensurepip|
So far everything works fine, but when I tried to install packages it 
didn't work.

Any help is appreciated, following is a detailed description.

I installed Ironpython on WinXP for the first time, then ensurepip, and 
tried getting pyvisa without success. Then went to a basic pip package 
as shown in the release info but it's not working.
Executing the line|ipy.exe -X:Frames -m pip install html5lib|gives me an 
error as follows:

|   File "C:\Archivos de programa\IronPython 2.7\lib\site-packages\pip\_vendor\requests\packages\urllib3\packages\ssl_match_hostname\_implementation.py", line 88, in match_hostname
     for key, value in sub:
ValueError: too many values to unpack
|

After digging a bit the problem is that the following code

|sub = ('txt1','txt2')
for key,value in sub:
    print key,value
|

gives the error

|File "<stdin>", line 1, in <module>
ValueError: too many values to unpack
|

I don't understand why this happens, any ideas?

After this was detected, if I modify _implementation.py to work around 
this error, I get a new error which I don't get. The log file follows:

It seems the server is reporting the wrong hostname?
Anyone knows what's happening here?
