* ~nix-tools~
4+
5+
[[https://buildkite.com/input-output-hk/nix-tools][https://badge.buildkite.com/8c5ed154c28db5d7184560c8000e57180b2b362b7a0431602e.svg]]
6+
7+
~nix-tools~ is a set of Haskell → Nix tools to integrate Haskell
8+
projects into Nix build environments.
9+
10+
* Motivation
11+
12+
Why (yet) another conversion to Nix? ~cabal2nix~ has served the Nix
13+
community well for a long time. It does have short comings that can't
14+
be easily overcome without significantly altering ~cabal2nix~. These
15+
are among others:
16+
17+
- hard coded flags / operating system upon invocation
18+
- package resolution in cabal2nix instead of nix.
19+
20+
Ideally we'd convert cabal files into Nix expression and retain almost
21+
everything from the cabal file and let Nix deal with the expression
22+
afterwards.
23+
24+
~nix-tools~ explores this space of a very simple ~.cabal~ conversion
25+
into a ~nix~ expression and then doing the lifting in Nix.
26+
27+
* QuickStart
28+
29+
View the [[https://input-output-hk.github.io/haskell.nix/][haskell.nix documentation]] for instructions on how to get
30+
started with your own project.
31+
32+
* Building
33+
34+
To build all of the ~nix-tools~ using Cabal:
35+
36+
#+begin_example
37+
cabal new-build
38+
#+end_example
39+
40+
* Project Roadmap
41+
42+
Under the [[https://github.com/input-output-hk/haskell.nix][haskell.nix]]
43+
umbrella there are a few [[https://github.com/input-output-hk/haskell.nix/projects][GitHub Projects]]
44+
for tracking completion of the project goals. If you would like to
45+
follow or contribute to this effort then that would be a good place to
46+
start.
47+
48+
Please open bug reports in the
49+
[[https://github.com/input-output-hk/haskell.nix/issues][Haskell.nix issue tracker]].
