108. *nix just means operating systems that are like the old workhorse Unix. Some examples include Linux, FreeBSD, and Mac OS X (its kernel, Darwin, is based on BSD). The main relation between *nix and Ruby is just a pragmatic one; most Ruby developers seem to prefer to work on Unix-like OSes (typically Linux or Mac OS X).
知乎用户. Nix 软件管理是 Nix 系列工具的基础。. Nix 的一系列操作意在彻底解决软件之间依赖问题。. 或者说，解决提出问题的人（划掉）依赖本身。. 通过将软件作为一个 Nix 语言表达式的计算结果，而不是一个 build script 的副作用，Nix 很好的实现了这一目标 ...
Mar 31, 2018 · 1. It creates a new derivation, which when built will create/construct a new directory in the nix store. I believe that it generally works like this: NOTE: args below is the attrset passed to the buildEnv function. Create a new directory (let's call it out) in the nix store. For each drv (e.g. path to a derivation, or some other directory, in ...
May 20, 2017 · 79. First of all, default.nix and shell.nix have special meanings in Nix tool, but release.nix is a convenience one. Next, default.nix is used as a default file when running nix-build, and shell.nix is used as a default file when running nix-shell. Just like you said. Next, default.nix isn't used only for nix-build.
Dec 30, 2014 · I'm learning about nixos and nix expressions. In a project folder I created a shell.nix and I when I run nix-shell I want it to preset an environment variable for me. For example to set the PGDATA env var. I know there are several ways to write nix expression files (I'm not yet used to most of them). Here is my sample: shell.nix
Aug 20, 2018 · Since then, Nix has started to support systemd unit installations and since Catalina, macOS installations have become more complex too. This answer is not official documentation. The "curl | sh" installer for Nix on Linux does not install the Nix daemon, so the only things to delete are /nix, the line in ~/.profile and ~/.nix-profile.
Dec 27, 2017 · I'm using nix package-manager on macOS (Sierra). My intention is to write a nix expression that will install the existing fish nix package along with the Bass fish plugin. There are no existing
Dec 17, 2022 · 1. nix show-derivation expects its input as command line arguments. Lacking any inputs, it seems to default to looking up a flake. This would work, if it wasn't for *.drv producing too many results on my store: $ nix show-derivation --extra-experimental-features nix-command $(ls /nix/store/*.drv | head -n 1) bash: /run/current-system/sw/bin/ls ...
Jul 10, 2021 · Build dependencies are automatically recognized by Nix once they are used in any derivation call, but we never specify what are the runtime dependencies for a derivation. There's really black magic involved. It's something that at first glance makes you think "no, this can't work in the long term", but at the same time it works so well that a ...
Apr 5, 2022 · Components are installed from a set of Nix expressions that tell Nix how to build those packages, including, if necessary, their dependencies. There is a collection of Nix expressions called the Nixpkgs package collection that contains packages ranging from basic development stuff such as GCC and Glibc, to end-user applications like Mozilla ...
