Drop data/used-by.json and build-used-by.js; build-contributors.js now extracts USED-BY-BEGIN/END to used-by.swig.
Co-authored-by: Cursor <[email protected]>
Add data/used-by.json with build:used-by for README and docs homepage, playground demo capture, and shared home-section layout. Used by lists products with site logos; Financial Support keeps org and individual sponsors.

* docs: polish theme, playground, and reference pages
Improve readability of the docs site with updated light/dark tokens, shared
code-block styling, and playground editors that follow system color scheme.
Skip CookieHub on localhost, serve the browser bundle from theme source, and
use backtick titles on filter/tag reference pages for consistent navigation.

* docs: highlight npx in bash blocks and polish English copy
Use Prism insertBefore for CLI commands like npx, tighten tutorial and reference wording, and keep YAML titles free of backticks so sidebar and page headings stay correct.
Co-authored-by: Cursor <[email protected]>
* docs: restore lowercase filter and tag titles
Titles should match actual filter/tag identifiers (e.g. abs, append), not capitalized English labels.

* docs: add GitHub buttons and improve option docs
* chore: replace husky with prepush check
* docs: revamp homepage and switch to custom GitHub buttons
- Make the docs English-only by removing all zh-cn content, the language switcher UI, and related JS/config
- Rework homepage feature cards (Safe & Typed, Pure JavaScript, Shopify & Jekyll, Streaming) and refresh section colors/layout
- Replace buttons.github.io with custom Star/Sponsor buttons featuring a live star count and dark-mode support
- Drop the buttons.js script and tidy banner, header, footer, and share partials

* fix: restore tsconfig settings and changelog build
Re-add suppressImplicitAnyIndexErrors and downlevelIteration removed in
a75033e2c, which broke the rollup TypeScript build on CI. Drop zh-cn
changelog output now that translations were removed.

* fix(security): block Object.prototype filter/tag lookups (RCE)
`liquid.filters` and `liquid.tags` were plain `{}` so bracket access on
template-controlled keys inherited from `Object.prototype`. Most damaging:
`{{ x | valueOf }}` resolved to `Object.prototype.valueOf`, which the
filter pipeline called as a handler with `this = FilterImpl`; valueOf
returns its receiver, leaking `context`, `liquid`, `token` (and via them
parser, loader, fs) into the template — chain that with `group_by`/`where`
gadgets and an attacker reaches `Function`/`child_process` for RCE.
Same shape on the tag side: `{% constructor %}` bypassed the
"tag not found" assertion and crashed with a confusing message.
Use null-prototype storage so `liquid.filters[name]` / `liquid.tags[name]`
only resolve to explicitly registered entries. The existing
`assert(impl || !strictFilters)` and `assert(TagClass, ...)` now do the
right thing for `valueOf`, `toString`, `constructor`, `__proto__`,
`hasOwnProperty`, `isPrototypeOf`, `__defineGetter__`, etc.

* test: dedupe registry checks; merge filter prototype loop
Co-authored-by: Cursor <[email protected]>
* fix(context): use null-prototype scope and register objects
Add createScope(); use for bottom scope, spawn default, getAll merge, ctx.push frames, filter loops, include/layout blocks registers, and cycle groups. registers uses Object.create(null) and getRegister uses ??.
For-loop continue register defaults to 0 (not {}): Array.slice coerces plain {} but not null-prototype objects.
Export createScope from the package entry.

* revert(context): plain {} registers and getRegister ||
Registers are only mutated by tag implementations, not templates; keep null-prototype scopes/createScope for push frames.
Co-authored-by: Cursor <[email protected]>
* test(context): assert scope isolation without probing prototypes
Replace Object.getPrototypeOf checks for bottom() and getAll() with
'in' checks on typical Object.prototype names plus a merge assertion.

* test(e2e): assert constructor filter/tag lookups (node + UMD)
Co-authored-by: Cursor <[email protected]>
* test(context): cover Object.prototype keys under ownPropertyOnly
- Add getSync cases for constructor and valueOf on plain objects
- Remove scope storage tests that used the in operator
Co-authored-by: Cursor <[email protected]>
* refactor: remove createScope helper
Drop the exported helper and finish migrating call sites. Revert incidental context/for/include/layout churn so behavior matches mainline aside from the removal. Trim duplicate e2e and heavy Object.prototype loops in registry tests.

* fix(date): cap strftime widths and account padding in memoryLimit
- Clamp numeric strftime pad widths to MAX_STRFTIME_PAD (1024)
- Export estimateStrftimePaddingMemory for the date filter to charge memoryLimit
- Replace unbounded pad() concatenation loop with ch.repeat + single concat
- Add regression tests for clamping and memoryLimit on huge %width directives
Co-authored-by: Cursor <[email protected]>
* fix(date): harden strftime memory accounting and document security model
Move strftime memory charging into the same formatting path used for padding, enforce pre-allocation checks, and add regression tests for non-string date format PoCs. Add dedicated docs clarifying that memoryLimit is cooperative DoS mitigation and not strict heap isolation.
Co-authored-by: Cursor <[email protected]>
* docs(zh-cn): add security model docs for DoS limits
Add a Chinese security-model tutorial and link it from the Chinese DoS guide to clarify that memoryLimit is cooperative accounting, list uncounted custom conversion cases, and recommend avoiding fully user-defined templates in online services.
Co-authored-by: Cursor <[email protected]>
* docs: consolidate DoS docs into security-model pages
Merge DoS guidance into security-model docs in both English and Chinese, and remove the placeholder dos.md pages to avoid duplicate/redirect-only docs.
Co-authored-by: Cursor <[email protected]>
* docs: merge DoS details into security-model docs
Move the detailed parseLimit/renderLimit/memoryLimit explanations and examples into the English and Chinese security-model pages so content from the removed dos pages is preserved.
Co-authored-by: Cursor <[email protected]>
* docs: reorganize security-model structure for clarity
Restructure English and Chinese security-model docs into a consistent flow: security boundary, limits overview, per-limit details, and online service guidance.

* refactor(strftime): simplify %N width parsing logic
Use regex-backed width assumptions to simplify %N width normalization and padding memory accounting while keeping behavior equivalent.
Co-authored-by: Cursor <[email protected]>
* refactor(strftime): rely on memoryLimit for width control
Remove MAX_STRFTIME_PAD hard capping and rely on memoryLimit enforcement before padding allocation. Update strftime/date tests and security-model docs to match the new boundary and renderLimit caveats.
Co-authored-by: Cursor <[email protected]>
* fix(strftime): use add() once for padding, minimize churn
- pad(): replace per-char loop with a single add(str, ch.repeat(n)) call.
The earlier `probe[0] === ch` heuristic was wrong when ch happened to
equal a leading char of 'probe' (e.g. ch === 'p').
- strftime.ts: revert unrelated typing/structural refactors so the diff
contains only the memoryLimit threading and the %N memory charge.
- docs: rewire the deleted dos.html sidebar entry to security-model.html
(with localized labels) so the deleted page does not 404 from the
sidebar.

DISCLAIMER: This may not be the proper way to approach the issue.
Although the Markdown code is proper, on the website itself it is incorrectly rendered as "{{` and `}}".
The reason for the disclaimer above is that I’m imagining this may be an issue at the content rendering level, and my fix here is just a workaround of that issue. — Given this, I’ll not be offended if this PR of mine is rejected and closed. 🙂
