t3code-flake

Nix flake packaging T3 Code (pingdotgg's desktop app) for Linux and macOS, in two channels:

Package	Channel	Upstream tags
t3code	stable	v0.0.28
t3code-nightly	nightly	v0.0.29-nightly.20260725.899

default is the stable package, so nightlies are strictly opt-in. Nightlies are prereleases cut several times a day; expect the pinned version to move often and to occasionally be broken. Pinned versions and hashes for both channels live in sources.json; a scheduled GitHub Action bumps them and pushes to main when either channel has a newer release.

Supported systems

System	Artifact
x86_64-linux	AppImage wrapped with appimageTools.wrapType2
aarch64-darwin	.app bundle extracted from the arm64 zip
x86_64-darwin	.app bundle extracted from the x64 zip

Run it without installing

nix run github:winter-08/t3code-flake            # stable
nix run github:winter-08/t3code-flake#t3code-nightly

Add to a NixOS / home-manager / nix-darwin config

{
  inputs.t3code.url = "github:winter-08/t3code-flake";

  # in your system/home config:
  environment.systemPackages = [ inputs.t3code.packages.${pkgs.system}.default ];
  # or the nightly channel:
  # environment.systemPackages = [ inputs.t3code.packages.${pkgs.system}.t3code-nightly ];
  # or on darwin / home-manager:
  # home.packages = [ inputs.t3code.packages.${pkgs.system}.default ];
}

Both packages can be installed side by side. The nightly names its executable, desktop entry and icons t3code-nightly (upstream already labels the entry "T3 Code (Nightly)" and ships a separately named .app bundle), so nothing collides in a shared profile.

On macOS the package installs the .app under $out/Applications and creates a t3code (or t3code-nightly) symlink in $out/bin. Use mkAlias or copy the bundle into ~/Applications if you want it in Launchpad.

Updating manually

./scripts/update.sh            # both channels
./scripts/update.sh nightly    # just one

Requires jq and either gh or curl on $PATH. Prints one <channel> <version> line per channel that moved, otherwise stays silent, and exits 0 either way. Per channel it picks the newest release that has assets for all three supported systems, walking back past releases whose per-platform builds failed.

To pin an older version, edit sources.json by hand — the asset names and sha256 digests are listed on the upstream release page.

Auto-update workflow

.github/workflows/update.yml runs every six hours (and on demand via workflow_dispatch):

1. Runs scripts/update.sh against the latest upstream release on each channel.
2. If sources.json changed, builds both packages for x86_64-linux and aarch64-darwin to confirm the new hashes actually resolve.
3. Commits the bump with a message like t3code: bump stable v0.0.28, nightly v0.0.29-nightly.20260725.899 and pushes to main.

GITHUB_TOKEN needs contents: write (declared in the workflow). If main is protected, either allow the github-actions app to bypass the rule or switch the final job to gh pr create --fill plus gh pr merge --auto --squash.
