With libpcap you need privileges to access the network adapter to capture all traffic. You might want to be careful about security applications Stephan

Tabular ODS import

by Alistair Grant

Hi All, I've been working on the ODS importer for the Tabular package (http://ss3.gemtalksystems.com/ss/Tabular.html) and wanted to offer the opportunity for feedback before updating the code as it is likely to affect existing users. While the class structure of Tabular is designed to support multiple formats in theory, in practice the existing implementation is quite XLSX specific. I think that trying to extend the core Tabular classes to be a superset of all the functionality from the various formats (XLSX, ODS, etc.) will not be practical - I don't have a good enough understanding of all the formats to implement it in the first place, and certainly not to resolve conflicting attributes in any sensible way. The approach I've taken is to make the existing classes, which were intended to be format independent, abstract and create format specific subclasses, i.e. the existing TabularCell and TabularStyle become: TabularCell TabularXLSXCell TabularODSCell TabularStyle TabularXLSXStyle TabularODSStyle The modified code runs the existing test suite successfully without any modifications. I welcome any comments, suggestions, etc. Also, Tabular currently loads PharoExtras/XMLWriter and PharoExtras/XMLParser as dependencies. I've been using XMLSupport, which I thought I remembered reading was a replacement for XMLWriter and XMLParser, but now I can't find the reference. Is one generally preferred over the other? Thanks very much, Alistair

I've not used any compression stuff in Pharo, but be aware that GZip (*.gz files) is not Zip (*.zip files). http://www.differencebetween.net/technology/difference-between-zip-and-gzip/ cheers -ben On Tue, Apr 19, 2016 at 8:48 PM, Valentin Ryckewaert <valentin.ryckewaert(a)gmail.com> wrote: > Hi, > > I'm trying to unzip a file I did this : > GZipReadStream unzip:'aPath/myZip.zip' to: 'aPath/test' asFileReference > > It's not working and I don't really understand the doc of the method, why > does unzip want as first argument the name of the file only? > > Valentin

Hi, I'm trying to unzip a file I did this : GZipReadStream unzip:'aPath/myZip.zip' to: 'aPath/test' asFileReference It's not working and I don't really understand the doc of the method, why does unzip want as first argument the name of the file only? Valentin

Yes, check that you have 32bit (apt-get install libcairo2:i386) and that it's on one of those locations: '/usr/lib/i386-linux-gnu/libcairo.so.2' '/usr/lib32/libcairo.so.2' '/usr/lib/libcairo.so.2' On Tue, Apr 19, 2016 at 7:36 AM, Stephan Eggermont <stephan(a)stack.nl> wrote: > On 19-04-16 06:59, mathias arnaud nkeumo tsombeng wrote: > >> I have implement a method that is indicating where external library >> inthis case libpcap.

Hi Diego, Just yesterday I have added documentation explaining a bit how the process is working in my Type Inferer, it works in a different way than RoelTyper, but maybe you can get ideas of how enhance Roel's Any doubt please tell me.
