Q,
I'm using Nix package manager in these days. However it is not fit for switching multiple latest versions of Programming Language interpreter and compilers. Which resource resolve it?A,
Nix is a powerful package manager that allows you to easily install and manage software packages, including programming language interpreters and compilers. However, it can be challenging to switch between multiple versions of a programming language interpreter or compiler using Nix, as it has its own way to manage dependencies and versions.
One way to manage multiple versions of a programming language interpreter or compiler is to use the NixOS module system. NixOS allows you to define system configurations in a declarative way, and you can use this to create different profiles for different versions of a programming language interpreter or compiler.
Alternatively, you can use tools like nix-env or nix-shell to manage your environment. nix-env allows you to install, remove and switch between different versions of a package, and nix-shell allows you to enter a shell environment that has a specific version of a package installed.
Another popular tool is direnv, it allows you to automatically configure your environment based on the contents of a .envrc file in the current directory. This can be very useful for managing different versions of programming languages and their dependencies on a per-project basis.
You could also use asdf a language version manager it supports many languages and it allows you to switch between different versions with ease.
It's important to note that, each tool has its own benefits and drawbacks, and the best one for you will depend on your specific needs and use cases. You can try them and pick the one that better fits your needs.
devbox https://github.com/jetpack-io/devbox が流行りだした頃、まだ asdf とか *env とかでのバージョン管理に疲弊してるの・・・？ と自分で自分に思った。 ということで、https://github.com/digitallyinduced/ihp でもガッツリ使われているらしいことから気になってた Nix https://github.com/NixOS/nix を使いだしてみた。devbox はラッパーっぽい雰囲気なのと必要性がまだあんま良くわかってないので保留
なるほど、サックリ固定バージョン同士の組み合わせを自分の環境に導入出来てめっちゃ便利！ asdf だと先に chezscheme を導入しないといけない面倒さだった idris2 をサックリ入れられたのも嬉しい ( https://github.com/kachick/times_kachick/issues/201 はそこで引っかかった) CIの構築も楽なだけでなく、一定以上構成準備に時間がかかる場合は https://github.com/cachix/cachix 使うと速度向上も期待できそうだし
とは思ったんだけど、ガチガチに固めてるのと広範囲にカバーしてくれてる反面なのか最新版がなかなか中央集権リポジトリ?に無かったりする。 登場からほぼ一ヶ月経った Ruby も まだ 3.1 が最新だし、Crystal に至っては まだ 1年前の 1.2 で止まってる。PRを出してくれている方は居るんだけど、なかなかマージに至るまでが大変そう https://github.com/NixOS/nixpkgs/pull/195606 そもそも4500以上のPRが滞留してるし・・・ crystal 自身もビルドに Nix 使ってるみたい https://github.com/crystal-lang/crystal/blob/62b0adecc4cdfb4c84632a8f329d48983da97c6c/shell.nix だし、便利なのは間違いないと思うんだけど用途次第なんだろうなぁ 自分で定義すれば良いとは言え、気軽に出来るかというとちと大変そう
