For the low price of an enumerate() and a lambda you too can have the
incorrect line of code actually show up in the trace!

Lix

Lix is an implementation of Nix, a powerful package management system for Linux and other Unix systems that makes package management reliable and reproducible.

Read more about us at https://lix.systems.

Installation

On Linux and macOS the easiest way to install Lix is to run the following shell command (as a user other than root):

$ curl -sSf -L https://install.lix.systems/lix | sh -s -- install

For systems that already have a Nix implementation installed, such as NixOS systems, read our install page

Building And Developing

See our Hacking guide in our manual for instruction on how to to set up a development environment and build Lix from source.
