mailtrap-nur

Mailtrap NUR-style repository — Nix packages for Mailtrap tooling.

Layout follows nix-community/nur-packages-template.

Packages

Attribute	Description
mailtrap-local	Local email sandbox + catcher (mailtrap/mailtrap-local)

mailtrap-local installs the prebuilt release binary (same artifacts as Homebrew / GitHub Releases), so you get the real embedded Web UI. Platforms: x86_64/aarch64 on Linux and Darwin.

pkgs/mailtrap-local/default.nix is owned by goreleaser in mailtrap-local: each tagged release opens a PR here (same flow as the Homebrew tap).

Install

Flake (overlay into your own flake):

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    mailtrap-nur.url = "github:mailtrap/mailtrap-nur";
  };

  outputs = { nixpkgs, mailtrap-nur, ... }:
    let
      system = "aarch64-darwin"; # or x86_64-linux, …
      pkgs = import nixpkgs {
        inherit system;
        overlays = [ mailtrap-nur.overlays.default ];
      };
    in
    {
      packages.${system}.default = pkgs.mailtrap-local;
      # or: packages.${system}.mailtrap-local = pkgs.mailtrap-local;
    };
}

One-shot:

nix profile add github:mailtrap/mailtrap-nur#mailtrap-local
# Nix older than 2.25: nix profile install …
# or, without installing:
nix run github:mailtrap/mailtrap-nur#mailtrap-local

Both mailtrap-local and the mailtrap-sendmail symlink land in the profile.

Without flakes (shell.nix):

let
  pkgs = import <nixpkgs> { };
  mailtrap = import (builtins.fetchTarball "https://github.com/mailtrap/mailtrap-nur/archive/main.tar.gz") {
    inherit pkgs;
  };
in
  mailtrap.mailtrap-local

Or as a nixpkgs overlay (e.g. NixOS / home-manager nixpkgs.overlays):

[
  (import "${builtins.fetchTarball "https://github.com/mailtrap/mailtrap-nur/archive/main.tar.gz"}/overlay.nix")
]

Develop

nix-build -A mailtrap-local
nix build .#mailtrap-local

Add another package

1. Create pkgs/<name>/default.nix (use pkgs.callPackage — take deps from the pkgs argument, do not import <nixpkgs> inside the package).
2. Export it from root default.nix.
3. Mark broken packages with meta.broken = true so CI stays green.
4. If the package only supports some platforms, keep flake.nix systems aligned with those binaries.
