From a3e6415ba8cf1b8d2a1db40c06997d997eac8afc Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Tue, 12 Dec 2006 23:05:01 +0000 Subject: * 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. --- src/libstore/store-api.hh | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) (limited to 'src/libstore/store-api.hh') diff --git a/src/libstore/store-api.hh b/src/libstore/store-api.hh index 19c5d81cf267..d92b03df0621 100644 --- a/src/libstore/store-api.hh +++ b/src/libstore/store-api.hh @@ -79,9 +79,12 @@ public: /* Copy the contents of a path to the store and register the validity the resulting path.
