7 Overview
8 ========
9
10 We use the Nix package manager to handle our dependencies. In general we use the
11 packages out of the package collection `nixpkgs`. For frequently changing
12 dependencies for Python and JavaScript we use the tools which are described in
13 this section to generate the needed Nix derivations.
14
15
16 Python dependencies
17 ===================
18
19 We use the tool `pip2nix` to generate the Nix derivations for our Python
20 dependencies.
21
22 Generating the dependencies should be done with the following command:
23
24 .. code:: shell
25
26 pip2nix generate --license
27
28
29 .. note::
30
31 License extraction support is still experimental, use the version from the
32 following pull request: https://github.com/ktosiek/pip2nix/pull/30

36 Node dependencies
37 =================
38
39 After adding new dependencies via ``npm install --save``, use `node2nix` to
40 update the corresponding Nix derivations:
41
42 .. code:: shell
43
44 cd pkgs
45 node2nix --input ../package.json \
46 -o node-packages.nix \
47 -e node-env.nix \
48 -c node-default.nix \
49 -d --flatten
50
51
52 Bower dependencies
53 ==================
54
55 Frontend dependencies are managed based on `bower`, with `bower2nix` a tool
56 exists which can generate the needed Nix derivations:
57
58 .. code:: shell
59
60 bower2nix bower.json pkgs/bower-packages.nix
