Hy
Installation
Installation without packages
You can install hy
via nix-env or by adding it to configuration.nix
by reffering to it as a hy
attribute. This kind of installation adds hy
to your environment and it succesfully works with python3
.
::: {.caution}
Packages that are installed with your python derivation, are not accesible by hy
this way.
:::
Installation with packages
Creating hy
derivation with custom python
packages is really simple and similar to the way that python does it. Attribute hy
provides function withPackages
that creates custom hy
derivation with specified packages.
For example if you want to create shell with matplotlib
and numpy
, you can do it like so:
$ nix-shell -p "hy.withPackages (ps: with ps; [ numpy matplotlib ])"
Or if you want to extend your configuration.nix
:
{ # ...
environment.systemPackages = with pkgs; [
(hy.withPackages (py-packages: with py-packages; [ numpy matplotlib ]))
];
}
