Previous comment is getting long, but if you want to get rid of things like "googlecloud-sdk/platform/bundledpythonunix/bin" you can use: nix-locate --top-level --regex '^/bin/python3' Which will only show packages with "/bin/python3" in the root. Most of the time this is unnecessary, but since python gets vendored in a lot of packages, it comes up with this example.

I can't tell if you're joking, but I'm not sure how these results told you anything. I find nix-index and nix-locate entirely unusable.

    $ nix-locate --top-level -1 --regex '^/bin/python3'
    qtile.out
    python3Minimal.out
    python311.out
    python38.out
    python37.out
    python3Full.out
    python38Full.out
    sourcehut.python.out
    python39Full.out
    python39.out
    python37Full.out
    ihaskell.out

    $ nix-locate --top-level -1 --regex '^/bin/firefox'
    firefox-esr-102-unwrapped.out
    firefox_decrypt.out
    firefox-unwrapped.out
    firefox.out

The nix package search website is OK, but it doesn't let you filter by the names of installed binaries. A lot of the time, you have a question like "what nixpkgs attribute do i install in order to get the `python3` command". I recently wrote a command line tool that allows you to do this. It uses the same elasticsearch index as the search website, but allows more powerful filtering. If anyone is thinking of getting i…

nix-locate can also solve that problem

   [nextos@local:~]$ python3
   The program 'python3' is not in your PATH. It is provided by several packages.
   You can make it available in an ephemeral shell by typing one of the following:
     nix-shell -p graalvmCEPackages.graalvm11-ce-full
     nix-shell -p graalvmCEPackages.graalvm17-ce-full
     nix-shell -p graalvmCEPackages.python-installable-svm-java11
     nix-shell -p graalvmCEPackages.python-installable-svm-java17
     nix-shell -p ihaskell
     nix-shell -p python311
     nix-shell -p python311Full
     nix-shell -p python312
     nix-shell -p python38

What sort of time investment is required to get vaguely competent at nix? Mostly dabble in self hosting stuff and not sure it’s worthwhile.

A naive search is even easier. Right now, on NixOS: [nextos@local:~]$ python3 The program 'python3' is not in your PATH. It is provided by several packages. You can make it available in an ephemeral shell by typing one of the following: nix-shell -p graalvmCEPackages.graalvm11-ce-full nix-shell -p graalvmCEPackages.graalvm17-ce-full nix-shell -p graalvmCEPackages.python-installable-svm-java11 nix-shell -p graalvmCEPa…

I have zsh installed and it's not doing this. How does one get it to do this?
