From 3f192ac80ca421888c668896b63485486e1397ae Mon Sep 17 00:00:00 2001 From: Daniel Schaefer Date: Fri, 3 May 2019 14:30:29 +0200 Subject: Add builtins.hashFile For text files it is possible to do it like so: `builtins.hashString "sha256" (builtins.readFile /tmp/a)` but that doesn't work for binary files. With builtins.hashFile any kind of file can be conveniently hashed. --- tests/lang/eval-okay-hashfile.nix | 4 ++++ 1 file changed, 4 insertions(+) create mode 100644 tests/lang/eval-okay-hashfile.nix (limited to 'tests/lang/eval-okay-hashfile.nix') diff --git a/tests/lang/eval-okay-hashfile.nix b/tests/lang/eval-okay-hashfile.nix new file mode 100644 index 000000000..aff5a1856 --- /dev/null +++ b/tests/lang/eval-okay-hashfile.nix @@ -0,0 +1,4 @@ +let + paths = [ ./data ./binary-data ]; +in + builtins.concatLists (map (hash: map (builtins.hashFile hash) paths) ["md5" "sha1" "sha256" "sha512"]) -- cgit v1.2.3
