I have a software application that can be built and installed with stack
. I would like to offer a binary package as well for Linux and Mac. For this purpose I'm considering nix
, since, among other things, it can be used in Linux and Mac. This will save me the trouble of having to maintain two package types.
After reading about how nix
packages are defined, I would expect that a stack
based project could be built with a configuration that would look like:
{ stdenv, fetchurl, stack }: # we need to depend on stack
stdenv.mkDerivation {
name = "some-haskell-package-0.1";
builder = ./builder.sh; # here we would call `stack install`
src = fetchurl { # ...
};
}
Looking at the resources available online, I cannot find any description of how this could be done. I don't know if this means that stack
and nix
are not intended to be used in this way.
The only thing I could find in the manual is how stack
can use nix
, and a stack
to nix
conversion tool.
I'm also open to alternatives for multi-platform packaging.
With this recent merge, I am able to build and installed a simple stack project using following steps:
- Create new
hello
project withstack new hello
Add following lines to
stack.yaml
nix: enable: true shell-file: default.nix
Create
default.nix
with (import <nixpkgs> { }); haskell.lib.buildStackProject { name = "hello"; src = ./.; }
At this point, I am able to run nix-build
to build the project and result will be at ./result/bin/hello-exe
If I want to install, I would run nix-env -i -f default.nix
Side note: nix-build
will download stack's build plan every time it run.
I want to incrementally build my project while making changes so I mainly just drop in the shell and call stack build
there.
