The URL you gave returns binary data, not text (which is wrong, CSV is a text based format).
Anyway, a quick fix is to use #asString
(NeoCSVReader on: '
https://github.com/sudar/pig-samples/raw/master/data/tweets.csv' asUrl retrieveContents asString readStream) skipHeader; upToEnd.
But that is really a hack, because we cannot know what encoding is being used (the tweets could contain anything). You could also try to use #utf8Decoded instead of #asString

Apparently SmallInteger>>codePoint does not exist...

Sorry about that
No problem.
Actually, many people use ZnEasy because it seems simple, but it can be deceiving (like in this case).
If you want the shortest possible code in scripting I would suggest doing it like this:
'http://bit.ly/exampleCSV' asUrl retrieveContents.
'http://zn.stfx.eu/zn/numbers.txt' asUrl retrieveContents.
The #retrieveContents message will fail unless there is a proper HTTP 200 OK response. And it is all cool unary messages !

Hi Sven,
There is apparently a problem in NeoCSVReader. #codepoint is apparently missing
The following code raises an exception:
urlAsString := 'http://bit.ly/exampleCSV'.
Can you give me a working URL so that I can try myself ?
content := (ZnEasy get: urlAsString) contents readStream.
lines := (NeoCSVReader on: content)
skipHeader;
upToEnd.
I loaded NeoCSV using:
Gofer new
smalltalkhubUser: 'SvenVanCaekenberghe' project: 'Neo';
package: 'ConfigurationOfNeoCSV'; load.
(Smalltalk at: #ConfigurationOfNeoCSV) loadBleedingEdge.
Any idea?
Cheers,
Alexandre
