1. win32libs-bin/libxml depends on iconv, while other packages requiring iconv depends on win_iconv 2. wget is listed as dependency for many packages. For my opinion wget should only be the first dependency of virtual/base and nowhere else. An issue i found while running python bin\dependencies.py enterprise5/kdepim-e5 > kdepim-e5.dot is that a debug line is printed at the top of the dot file - not sure yet where it came from. Another little issue i found is a naming problem - In portage.py there is a new function def get_packages_categories - in emerge function are normally written in Camel Case with first character lowercase, so it should be def getPackagesCategories One extension I suggest is to change def __str__(self): 140 return "%s:%s:%s:%s" % ( 141 self.category, self.package, self.version, self.tag) into def __str__(self): 140 return "%s\\n%s\\n%s\\n%s" % ( 141 self.category, self.package, self.version, self.tag) which increases readability by printing each attribute in a new line. Also with this change the graph is smaller in width. If you you forced to use the original style, we should add a parameter to switch the output format. Second I suggest to add an additional emerge command like emerge --print-dependencies <package> to make this features callable in the normal way. > II - emerge -k > I will take a look later > III - emerge -j > I will take a look later > You find our emerge changes in the intevation-merge branch [4]. > It would be nice to have merged them back into trunk. :-) > I will take some time for merging the stuff into trunk. Many thanks for contributing this stuff. Regards Ralf _______________________________________________ Kde-windows mailing list [email protected] https://mail.kde.org/mailman/listinfo/kde-windows
