From 48b7b222491b2799e265cda9a0b8be0d5d8eb3c0 Mon Sep 17 00:00:00 2001 From: Ben Sima Date: Mon, 31 Jul 2023 10:15:34 -0400 Subject: Prototype nix expression generation There are some limitations to this implementation: 1. Using `runCommand` means this will re-run any time anything changes in the repo. The solution is to use the existing import detection to make a list of source files, and put that into a `stdenv.mkDerivation`, which I'll do next. 2. The `NeatInterpolation` usage is ugly. The templated nix code should be extracted into its own file, such as `Biz/Bild/Builder.nix`. 3. I'm not actually calling it yet. The ideal thing would be to call `nix-instantiate`, get the output drv path, and then call `nix-store --realise` on that. To do that I need to refactor my `proc` function to return stdout to the calling function, and I should probably just make helper functions like `nixInstatiate :: Target -> IO DrvPath` and `nixStoreRealise :: DrvPath -> NixStorePath`, or something like that. --- Biz/Bild/Example.hs | 5 +++++ 1 file changed, 5 insertions(+) create mode 100644 Biz/Bild/Example.hs (limited to 'Biz/Bild') diff --git a/Biz/Bild/Example.hs b/Biz/Bild/Example.hs new file mode 100644 index 0000000..f812707 --- /dev/null +++ b/Biz/Bild/Example.hs @@ -0,0 +1,5 @@ +-- : out example +module Biz.Bild.Example where + +main :: IO () +main = print "hi" -- cgit v1.2.3
