Great work (as usual!), @Seth0x41 Re: const isSharedArrayBufferSupported = typeof SharedArrayBuffer !== 'undefined';When I enable it, I get an error which seems to be related to this code Re: cache Re: formatting I have some relatively minor comments. I will add these on code. Please run Thank you :) |

WalkthroughAdds Zig 0.14.0 WebAssembly support with a WASI runtime, source-aware compilation cache, retryable initialization, language registration, starter template, UI entries, SDK types, and documentation. ChangesZig WebAssembly support
Priority: ⬇️ Low Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The Zig starter can become unusable after initialization failure or conceal compilation/runtime failures as successful output. Its retry and input handling also remain unreliable, so these issues should be fixed before merge. Sequence Diagram(s)sequenceDiagram

In `@docs/docs/languages/zig-wasm.mdx`:
- Around line 98-100: Update the “Code Formatting” section in the Zig WASM
documentation to either remove the empty heading or add a clear statement that
formatting is not currently available; do not leave the section without
explanatory content.
In `@functions/vendors/templates.js`:
- Line 73: Add a `zig-wasm` entry to the starter-template map in `templates.js`,
including the metadata required by `functions/utils.ts` so the lookup returns
the correct template name instead of an empty value.
In `@src/livecodes/languages/zig-wasm/lang-zig-wasm-script.ts`:
- Line 276: Update the flow around cacheWasm and the subsequent
WebAssembly.compile call so each cache miss compiles wasmData only once. Reuse
the module returned or stored by cacheWasm instead of compiling it again, while
preserving the existing cached-module behavior.
- Line 80: Update the cache insertion logic around baseIdx and entryCount so
metadata entries are cleared or evicted before the 21st entry would exceed
metaView’s 20-entry capacity. Keep entryCount and data-offset updates consistent
with the eviction, ensuring every stored source version remains retrievable.
- Line 284: Move the livecodes.zig.init await and its readiness check inside the
existing try block in runZigCode, ensuring initialization failures follow the
current error handling path that sends loading: false and publishes an error
result.
- Line 334: Update the catch handling in runZigCode to import and use
getErrorMessage from ../../utils/utils instead of asserting err as Error and
reading .message, preserving meaningful failure text for Error and non-Error
thrown values.
In `@src/livecodes/templates/starter/zig-wasm-starter.ts`:
- Line 45: Update the count handling around parseInt so the parsed value is
computed once and validated with Number.isNaN or Number.isInteger before
assigning window.count; retain the existing assignment only for valid numeric
output.

The ??=-guarded livecodes.zig.loaded breaks the live-reload flow: after an edit, the result page resolves loaded against the previous run's already-resolved promise and shows stale output instead of the new code's result. Details inline.

There was a problem hiding this comment.
The guard is keyed by hash alone while findEntry and compiledModules are also hash-keyed, so on a genuine createHash collision the equality check can pass against an older entry's bytes: sourceKeys holds only the latest source for a given hash, and findEntry returns the first hash match. The comment's "never return a cached module compiled from different code" guarantee therefore doesn't hold as written — store the exact source per entry (or check it per entry) if collision-safety is the goal. Practically hard to trigger, so not blocking.

Handle Zig initialization failure before awaiting loaded.
livecodes.zig.loaded rejects when the runtime initialization fails. This unhandled rejection exits the load handler before it enables or wires the button. The starter then remains disabled with Loading..., and users cannot trigger the retry path.
Restore a rejection handler that shows the failure state, enables a Retry button, and calls livecodes.zig.run(livecodes.zig.input).

Do not render fallback output after a Zig execution error.
The click handler receives error but ignores it. When output is null, this fallback renders zig and 0, enables the button, and hides the compiler or runtime failure. Handle error before calling update() and show a retryable error state.

The template rename zig → zig-wasm in this commit was not propagated everywhere: npm run typecheck:app now fails on command-menu-actions.ts, and the user-facing "Load starter template" buttons still point at the old zig template name. All in scope of the rename this delta introduced.
Reviewed changes — changes since the prior Pullfrog review (47dd3c5, commit e8a99c6 "fix live reload"):
- Renamed the starter template
zig→zig-wasmin the SDKTemplateNameunion and the regenerated template manifests (functions/vendors/templates.js,server/php/inc/starter-templates.json). - Fixed the live-reload staleness bug —
livecodes.zig.loadedis now reassigned on every script evaluation instead of??=-guarded,readyis reset at the top of each eval, anduntar/wasiare persisted onlivecodes.zigso re-evaluations reuse the loaded dependencies. - Simplified the Zig starter — removed the failure/retry block, added an
(output || 'zig\n0')fallback for the initial counter parse, and switched the count validation toNumber(count).
Technical details
# Propagate the `zig` → `zig-wasm` starter-template rename
## Affected sites
- src/livecodes/UI/command-menu-actions.ts:329 — `'zig'` passed to `stringUnionToArray<TemplateName>()`; `'zig'` is no longer a member of `TemplateName` (sdk/models.ts changed in e8a99c6) → **`npm run typecheck:app` fails with TS2345**.
- src/livecodes/html/language-info.html:367 — `href="?template=zig"`, `data-template="zig"` → the Zig language-info "Load starter template" button resolves no template (loadStarterTemplate matches by exact name) and will show "Failed loading template".
- src/livecodes/i18n/locales/en/language-info.lokalise.json:1080 — `zigWasm.link` translation carries `?template=zig` / `data-template="zig"` (re-export after fixing language-info.html).
- docs/src/components/TemplateList.tsx:74 — `{ name: 'zig', ... }` → generates a `?template=zig` link on the docs site.
- docs/docs/languages/zig-wasm.mdx:74,121 — `<LiveCodes template="zig">` and `?template=zig` links.
## Required outcome
- Replace all remaining `zig` template-name references with `zig-wasm` (the language-info button, i18n string, docs list + links), and regenerate the i18n export.
## Note
- The runtime script and starter use `zig-wasm` (language name) consistently — only the template-name references above are stale.DeepSeek Flash (free via Pullfrog for OSS) ｜ 𝕏

This delta renamed the starter template zig → zig-wasm in the TemplateName union (sdk/models.ts) and the regenerated manifests, but this entry still passes 'zig', so npm run typecheck:app now fails: TS2345: Argument of type '"zig"' is not assignable to parameter of type 'TemplateName'. Update to 'zig-wasm'.
Technical details
# Fix TemplateName mismatch after template rename
## Affected sites
- src/livecodes/UI/command-menu-actions.ts:329 — `'zig'` no longer a `TemplateName` member (renamed to `'zig-wasm'` in e8a99c6)
## Required outcome
- Change `'zig'` → `'zig-wasm'` here so the starter-templates command palette builds and typechecks.
## Also
- Same stale `?template=zig` / `data-template="zig"` references exist in `src/livecodes/html/language-info.html`, i18n `zigWasm.link`, `docs/src/components/TemplateList.tsx`, and `docs/docs/languages/zig-wasm.mdx`.| > | ||

The template was renamed to zig-wasm in this commit, but the Zig language-info "Load starter template" button still links to ?template=zig with data-template="zig". loadStarterTemplate matches templates by exact name, so clicking it will hit the "Failed loading template" error. Update both attributes (and the i18n zigWasm.link translation) to zig-wasm.
Technical details
# Update starter-template button to renamed template
## Affected sites
- src/livecodes/html/language-info.html:367 — `href="?template=zig"`, `data-template="zig"`
- src/livecodes/i18n/locales/en/language-info.lokalise.json:1080 — `zigWasm.link` carries the same `?template=zig` / `data-template="zig"` (regenerate after fix)
- docs/src/components/TemplateList.tsx:74 and docs/docs/languages/zig-wasm.mdx:74,121 — docs links to `?template=zig`
## Required outcome
- Change all `zig` template-name references to `zig-wasm`, then run `npm run i18n-export`.| const button = document.querySelector("#counter-button"); | ||

This whole block reverted the failure/retry handling that the previous commit (b843877) added per the coderabbit "don't leave the button stuck in Loading" finding. livecodes.zig.loaded still rejects on init failure (failLoaded in the runtime), so now await livecodes.zig.loaded throws unhandled inside the async load listener and the button stays disabled with "Loading..." forever — nothing consumes the rejection. Tiny suggestion: wrap the await in try/catch and at minimum surface livecodes.zig.error.
Technical details
# Starter no longer handles init failure
## Affected sites
- src/livecodes/templates/starter/zig-wasm-starter.ts:26 — bare `await livecodes.zig.loaded`; prior try/catch + Retry removed in e8a99c6
- Runtime still rejects: src/livecodes/languages/zig-wasm/lang-zig-wasm-script.ts:406-412 (`failLoaded`), 417-430
- Docs contradict the code: docs/docs/languages/zig-wasm.mdx:68 documents `loaded` as rejecting "if it fails to load"
## Required outcome
- On rejection, show `livecodes.zig.error` and re-enable the button (or remove the docs' rejection claim).
## Note
- Full retry recycling `window.count` was buggy (undefined at that point) — a simplified error display is enough.3 participants

Description
Notes:
The current code doesn't support ZLS yet, but we're working on adding support for it together. Right now, the code uses SharedArrayBuffer if the browser supports it, and falls back to ArrayBuffer if it doesn't.
This means ZLS can't be used yet, but the server can still run normally.
The second point is that I used a simple caching mechanism for lazy loading, to reduce lookup time to O(1).
The source code is converted to a 32-bit integer and used as a cache key.
I used 31 as a prime number because it provides good hash distribution, helps avoid collisions, and is fast .. Java uses it in hashCode.
0x7fffffff is a 31-bit positive integer that keeps hash values positive and avoids overflow issues.
Third point, I haven’t added a formatter yet. Do you have any suggestions for one?
Looking forward to hearing your feedback. :)
