This Nix derivation (e.g. what in dpkg and apt is called a 'package') for https://obsidian.md, appImage edition.
It's generally a lot fresher than the standard Obsidian found in the Nix repo.
My recommendation for NixOS is to install this in the usual fashion, via editing of /etc/nixos/configuration.nix, with
the nix file ends up living at /etc/nixos/packages/obsidian.nix.
Your let-statement might now look something like:
{ config, pkgs, ... }:
let
# ...
obsidian = pkgs.callPackage ./packages/obsidian.nix {};
in {
# ...
And then later, in the same file, under environment.systemPackages:
environment.systemPackages = with pkgs; [
# ...
obsidian
# ...
];
If you just want to build it and take a look at the build result, you can of course do that with nix-build ./obsidian.nix in this directory.
(It appears as a symlink named 'result')
