v10.0.0 — Honest native export + WebView target

Install/upgrade: pip install --upgrade eplang · PyPI

[10.0.0] — 2026-06-25

The "one codebase → web + Android + iOS + desktop" claim is now genuinely
true — and honest about how. EPL web apps rely on HTTP routing, a server-side
backend, and the web escape hatches Raw HTML / Script / Stylesheet, none
of which have a native-widget equivalent. The transliterating native targets
used to drop all of that silently, exit 0, and print "✓ generated" — so an app
whose UI is built from Raw HTML (the omniapp stress test, finding H2) looked
fully ported when ~90 % of it had been discarded. This release does two things:
it tells the truth about what transliteration can carry, and it adds a
WebView target that ships the real web app with nothing dropped.

Added

• WebView target (--webview) for android / ios / desktop — ships the
  real EPL web app instead of transliterating it:
  • android — a native WebView shell (epl/webview_gen.py) that loads the
    running EPL web server; default URL targets the emulator-to-host loopback
    (10.0.2.2) on the app's declared port, overridable with --url.
  • ios — a SwiftUI WKWebView shell (sources + Info.plist with local
    networking enabled).
  • desktop — a Python pywebview launcher that starts the EPL app and opens
    it in a native window. Because EPL is itself Python, this runs the whole
    app — UI and backend — with zero transliteration.
  • Nothing is dropped: routes, Raw HTML, Script, Stylesheet, and the
    db_* backend are exactly what you built for the web.
• Portability analysis (epl/native_portability.py): a single AST walk that
  produces an honest PortabilityReport of every construct that cannot be ported
  by the transliterating target — web routing/serving (Route, WebApp,
  Start ... on port, Send ...), web-only markup (Raw HTML, Script,
  Stylesheet), server-side storage (Store/Fetch), and web/db_* builtins —
  each with its line number and the reason it was dropped.
• Loud reporting on every transliterating build: epl android|ios|desktop
  prints a summary of unportable constructs to stderr and writes a full
  PORTING_REPORT.md into the output directory, including what did port and how
  to ship the real app via --webview.
• --strict flag for android/ios/desktop: exit non-zero (code 2)
  when any construct could not be ported, so CI no longer treats a lossy
  transliteration as success.

Notes

• The transliterating path changes no codegen output — it only reports the
  truth about coverage. Pure-logic EPL (functions, math, data) still ports
  cleanly with an empty report; for a real web app, use --webview.
• db_* calls are reported as unportable by the transliterating target until the
  native db bridge ships (H1); the WebView target runs them unchanged.
• Major version bump: native-export CLIs gain new behavior (loud reporting,
  --strict exit codes, --webview/--url), so this is 10.0.0.
