Verification record: DFV-AUDIT-20261021
Updated 21 October 2026 by Sir-Vigu. This is a scoped package-availability and staging audit, not a blanket security or compatibility certificate.
DF Code Compare — Previously staging-checked
The 1.0.0 release was staging-tested in the preceding batch (77 scoped assertions across that five-plugin batch). This pass confirmed the private archive exists and matched its inventory hash; no new universal compatibility/security certification is implied. Existing release screenshots and detailed boundaries remain below.

Before/after text diffs for developer communities
![[Image: df-code-compare.webp]](https://data-forums.com/images/vault-releases-20261021/df-code-compare.webp)
Screenshot from the isolated MyBB test forum; this is not a claim that the plugin is enabled on production Data-Forums.
What it is
Compare two plain-text versions inside a post, highlight inserted and removed lines, and download a unified text diff. Bounded client-side comparison; no external service.
What it does / Features
What is inside the download
Requirements
MyBB 1.8.40 is the tested target. PHP 8.1+ intended; runtime tests used PHP 8.4.26 and MariaDB 11.8.6. Use staging first on older MyBB releases or custom themes/editors. No API key or CDN dependency.
Install — step by step
1. Back up your forum files and database. Test on staging first.
2. Extract the ZIP. Upload the inc/ and jscripts/ directories to your MyBB root, preserving those paths. Do not upload to the ACP directory.
3. Admin CP → Configuration → Plugins → DF Code Compare → Install & Activate.
4. Admin CP → Configuration → Settings → DF Code Compare; review the settings below.
5. Try the example on a test thread before announcing it to members.
Settings
Enable DF Code Compare: on/off. No additional tables or template edits.
How to use
Testing — evidence and boundaries
Real MyBB parser; script/HTML escaping; missing separator; 200-line cap; literal code example; actual +3/-2 change count; downloadable unified diff; mobile parent-width fit; lifecycle.
Tested in an isolated stock MyBB 1.8.40 forum with PHP 8.4.26, MariaDB 11.8.6 and Chromium. The batch passed 25 PHP/MyBB integration assertions, 26 browser assertions and 26 lifecycle assertions. These are scoped tests, not a third-party security audit. Older MyBB releases, other SQL engines, Safari/Firefox and third-party themes/editors are not certified by this test run. These five plugins are distribution releases and are NOT enabled on the production Data-Forums forum.
Known limitations / privacy
Line-level comparison, not syntax highlighting or a Git merge engine. No intra-line highlighting, three-way merge or file upload. Exactly one separator line === AFTER === is required. Maximum 200 lines per side and 64 KiB per block. Multiple blocks per post are supported; nested comparison blocks are not. Without JavaScript, Before/After remain readable but the computed diff and export require JavaScript.
Deactivate / uninstall
Admin CP → Plugins → Deactivate stops the plugin on subsequent requests and keeps its configuration/data. Uninstall removes this plugin’s settings. Stored thread/post contents are not edited; custom MyCode may appear literally while the plugin is disabled.
Changelog
1.0.0 — 21 October 2026: initial release. No earlier version to upgrade from.

What it is
Compare two plain-text versions inside a post, highlight inserted and removed lines, and download a unified text diff. Bounded client-side comparison; no external service.
What it does / Features
- Explicit Before and After panes plus a unified change view.
- Longest-common-subsequence line comparison, bounded at 200 lines per side to limit browser work.
- Added and removed lines use both +/- prefixes and colours, not colour alone.
- Downloads a unified text diff with before/after headers.
- All input is displayed as escaped plain text. JavaScript does not execute submitted code.
- No CDN, external API, accounts or recurring service fee.
