This is the initial review of PR #1035 (45b70170, single commit against develop), which adds Haskell as a client-side language that runs GHC-in-browser (GHC 9.14.0.20251031) inside a Web Worker.
- Runtime: new
languages/haskell/*— a pass-through compiler spec, a worker that extracts the GHC rootfs withbsdtar.wasmunder WASI and drivesDyLDBrowserHost/myMain, and a serialized runner with separate boot/run timeouts and worker teardown/respawn. - DOM bridge:
livecodes.haskell.{run,loaded,output,error,exitCode}, worker URL derived from the content-hashedlang-haskell-worker.jsand a classic Blob worker;runneris??=-guarded whilerun/loadedare reassigned per evaluation, matching the repo's live-reload pattern. - Wiring: worker/script added as esbuild iife entries, vendor URLs for the GHC rootfs/dyld, bsdtar and WASI shim,
text/haskellscriptType, and thehaskell/hslanguage + template unions. - Surfaces: starter template, docs page, language-info section + en i18n, command menu, docs sliders/template list, Storybook, PHP/Cloudflare template maps, vendor licenses, README count.
- Tests: 5 runner unit tests (fake timers, mock worker) and a Playwright starter E2E covering compile errors and recovery.
I verified locally that the 5 runner tests pass, tsc --noEmit -p tsconfig.json is clean, both i18n test scripts pass, the worker implementation mirrors the upstream ghc-in-browser demo at the pinned commit, and @live-codes/monaco-languages@0.3.2/dist/haskell.js exists so the Monaco provider resolves. I found no correctness or concurrency defects in the runner, worker, or live-reload integration.

Reviewed changes
This is an incremental review of the three commits pushed after the initial review (45b70170): 774a7106 (security), e0f57ee6 (docs), and 7bc76830 (review findings).
- postMessage origin: the loading-state
parent.postMessagecalls inlang-haskell-script.tsnow target a computedparentOrigin(ancestorOrigins[0]→ referrer origin →location.origin) instead of'*'. - Runtime integrity:
bsdtar.wasmis now hashed withcrypto.subtle.digest('SHA-256')and compared against a newbsdtarWasmSha256constant beforeWebAssembly.instantiate. - Hard-coded paths: the
/tmpGHC paths were replaced with aghcRuntimeDirectoryconstant (with aNOSONARcomment), preserving behavior. - Starter i18n: the starter heading/loading text moved into
templates.haskell.heading/templates.haskell.loading, with matchingencatalog and Lokalise keys. - Docs: JSDoc added on
createHaskellRunner.
I re-verified locally: the runner tests pass, tsc --noEmit is clean, the i18n export test passes, and the new bsdtarWasmSha256 matches the current upstream bsdtar.wasm digest. No new correctness defects were introduced by these commits.

Translate the Haskell values for the affected locales.
The i18n guide defines non-English locale resources as translated text. The cited German, Spanish, Dutch, and Portuguese resources contain English Haskell values instead. fallbackLng: 'en' applies only when a key is missing; these keys exist, so users receive the English values directly.
Translate the cited TypeScript resources and regenerate the matching .lokalise.json files. Preserve all interpolation tags.

src/livecodes/i18n/i18n.ts uses English only when a locale key is missing. These Haskell keys exist with explicit English values in both the TypeScript resources and matching Lokalise JSON files. Users can therefore see English descriptions, link labels, headings, loading text, and starter labels.

Add Urdu and Simplified Chinese translations for the Haskell entries.
The cited locale files contain English Haskell metadata and template labels. When users select Urdu or Simplified Chinese, they can see these English values. Add the translations and keep each TypeScript locale file synchronized with its .lokalise.json file. The repository permits source changes before Lokalise translations are complete, so this is a minor localization issue rather than a merge-contract violation.

This is an incremental review of 9dce2cb (fix: address final Haskell review findings), the only commit pushed after the prior Pullfrog review at 7bc76830. It resolves the four open threads from the previous reviews and introduces no new defects.
- Self-hosted
bsdtar.wasm: added the binary undersrc/livecodes/assets/wasm/, removed the unpinnedbsdtarWasmUrl, and resolved the URL relative todocument.currentScript.src; the shipped file's SHA-256 matchesbsdtarWasmSha256, so the integrity pin is now stable. - GHC rootfs integrity:
verifyBsdtarWasmbecame a genericverifySha256, and the pinnedrootfs.tar.zstis now checked against a newghcRootfsSha256(I downloaded the pinned artifact —35f68f56…matches). - Result-loading origin check:
handleResultLoadingandshowResultModeDrawerincore.tsnow also requireevent.origin === sandboxService.getOrigin(), matching the existing console/compiler handlers. parentOriginrobustness:lang-haskell-script.tsnow short-circuits standalone contexts tolocation.originand falls back to'*'when neitherancestorOriginsnor a parseable referrer is available.- Locale backfill:
haskellandtemplates.haskell.*keys were added to all 18 non-enlanguage-info.ts/translation.tscatalogs (and their Lokalise JSON), and the bsdtar license link is commit-pinned.
I re-ran the focused runner tests (5 passed) and tsc --noEmit (clean), verified both new SHA-256 pins against the actual artifacts, and confirmed via the WPT location-ancestor-origins.sub.html cases that ancestorOrigins[0] is the immediate parent origin, so the Haskell parentOrigin targets window.parent correctly even in nested SDK embeds. The result iframe is sandboxed with allow-same-origin and served from the sandbox origin, so the new core.ts check does not see opaque "null" origins.

Thank you @sharno Do you think we can get stdin to work, of course non-interactively, similar to other languages? (e.g. https://dev.livecodes.io/?template=rust-wasm). Otherwise, I will do some modifications to keep consistency with other languages and the project conventions. |

Hi Hatem — I investigated this request. The current I recommend keeping the documented stdin limitation in this PR. The clean follow-up is an upstream — OpenCode (AI coding agent) |

the model provider had a temporary upstream failure. The provider refused or dropped the request mid-run — nothing in your repo or your credentials is at fault. Re-trigger Pullfrog; if it keeps happening, check the provider's status page.
