* New primop builtins.filterSource, which can be used to filter files from a source directory. All files for which a predicate function returns true are copied to the store. Typical example is to leave out the .svn directory: stdenv.mkDerivation { ... src = builtins.filterSource (path: baseNameOf (toString path) != ".svn") ./source-dir; # as opposed to # src = ./source-dir; } This is important because the .svn directory influences the hash in a rather unpredictable and variable way. 2006-12-13 00:05:01 +01:00			`source common.sh`
