# Build & release

## Versioning — "Build n"

Sublime-style: the version IS the commit count. `scripts/gen-version.ts` runs
`git rev-list --count HEAD` + `git rev-parse --short HEAD` and writes the
**gitignored** `src/shared/version.gen.ts` (`BUILD = {number, commit, date,
electrobun}`). It is regenerated by `postinstall` and at the start of every
`dev`/`build`/`start`/`release` script; committing it would bump the count it
records, hence gitignored. Fresh checkouts fail `tsc` until `bun install` has
run once (postinstall creates the file). `BRANDING.version` stays
semver-shaped (`0.1.<n>`) for electrobun's config/updater; `BRANDING.buildLabel`
("Build n") is what humans see (About box, options popover).

## Dev loop

- `bun run dev` — gen-version → scripts/dev.ts: starts `ng serve` (HMR) and
  `electrobun dev --watch`, with `DEV_SERVER_URL` pointing the webviews at the
  dev server (only honored on the dev channel and only if the server answers).
- `bun run build` — gen-version → Angular build → `electrobun build`
  (**dev channel** — fine for boot checks, NOT a release).
- `scripts/node-version-shim.ts` (preloaded via `bunfig.toml`, root AND ui/)
  fakes a Node version the Angular CLI accepts under Bun. Both preloads are
  load-bearing.

## Release builds

`bun scripts/release.ts [--target mac-arm64|mac-x64|win-x64]` (default: host).
Steps: gen-version → gen-icons → Angular build → `electrobun build
--env=stable` → copy/rename artifacts into
`release/<target>/miniSCP-Build<n>-<target>.*`.

Facts the script encodes:

- **`--env=stable` is mandatory for releases** — the CLI defaults to the dev
  channel (different app name `miniSCP-dev`, no distributable artifacts).
- **No OS cross-compile.** The CLI builds for its host (its `targets` config
  field is unread in 1.18.1); packaging needs host tools (codesign/hdiutil on
  macOS, rcedit/PowerShell on Windows). Hence one script run per artifact, on
  the matching machine; `win-x64` on a non-Windows host errors out.
- **mac-x64 from the arm64 Mac (Rosetta)**: the script downloads electrobun's
  x64 CLI binary once (`electrobun-cli-darwin-x64.tar.gz` from the GitHub
  release matching the installed version, cached at
  `~/.cache/miniscp/electrobun-cli-x64-<ver>/`) and runs it directly —
  Rosetta translates it, the CLI sees `process.arch === "x64"`, downloads the
  `dist-macos-x64` core into the electrobun package dir on first use, and
  packages a genuine x64 app. Note: Bun's `fetch`→`Bun.write` streaming hung
  on the GitHub redirect chain; the script uses `curl -fsSL` deliberately.
- **Core binary downloads**: the installed npm package ships mac-arm64
  binaries only; other `dist-<os>-<arch>` cores are fetched from
  `github.com/blackboardsh/electrobun/releases` at build time — network to
  GitHub is a build-time requirement on every fresh machine/runner.
- **Artifact shapes** (stable channel, in `artifacts/`): macOS →
  `stable-macos-<arch>-miniSCP.dmg` + `.app.tar.zst` + `update.json`
  (updater feed); Windows → `stable-win-x64-miniSCP-Setup.zip`
  (self-extracting installer → `%LOCALAPPDATA%`) plus the script's own
  **portable zip** made from the assembled app folder under
  `build/stable-win-x64/` (layout to confirm on the first real Windows build —
  the step warns instead of failing).
- The script filters artifacts by app name, so stale artifacts from older
  brandings don't get collected.

## CI (Gitea Actions)

`.gitea/workflows/release.yml` — tag-triggered (`build-*`), macos + windows
runner matrix, each running the same release script; inert until act_runners
with those labels are registered. Needs `fetch-depth: 0` (the build number is
the commit count). Runner prereqs are commented in the workflow file.

## Icons

`scripts/gen-icons.ts` (resvg, dev-time): renders `assets/logo.svg` into the
macOS iconset + `icon.png`, a multi-size `assets/icon.ico` (Windows installer/
taskbar, wired via `electrobun.config.ts win.icon`), the macOS tray template
PNG from `assets/tray/tray-glyph.svg`, and a small colored Windows tray PNG.
Rerun after touching either SVG; outputs are committed (build inputs).

## electrobun config notes

`electrobun.config.ts`: app identity comes from `BRANDING`; `build.bun.external`
must keep `["cpu-features", "*.node"]` (ssh2's optional native accelerators —
bundling them breaks the build; runtime falls back to pure JS);
`build.copy` ships the Angular dist and tray assets into `views://`;
`bundleCEF: false` everywhere (system WebKit / WebView2).
