Tachyon Edge Images Glossary

Tachyon Edge Images is a WordPress plugin that rewrites image URLs to a Tachyon Server. It replaces the Reference Plugin without any configuration changes and fixes the Reference Plugin’s bugs as Deviations.

Language

Reference Plugin: Human Made’s tachyon-plugin 0.11.1, the upstream release. Tachyon Edge Images is measured against it. Avoid: original plugin, upstream, the fork

Public API: The constants, global functions, class, public methods and tachyon_* hooks of the Reference Plugin that themes and other plugins rely on. Avoid: interface, surface

Compatible: Has the same Public API as the Reference Plugin and generates the same URLs for the same input, except where a Deviation applies. Avoid: drop-in, parity

Deviation: A documented difference from the Reference Plugin. It fixes output that no working site can depend on, such as a malformed URL, a PHP warning, the wrong image size, or the editor showing resized images.

Plugin Quirk: Odd behaviour of the Reference Plugin that is kept on purpose and documented, because sites may depend on it. Avoid: bug, Release Quirk (that term belongs to Tachyon Edge)

Tachyon Server: The image service that TACHYON_URL points to: Reference Tachyon or Tachyon Edge. Avoid: backend, CDN, Origin

Stand-down: The state in which Tachyon Edge Images does nothing because the Reference Plugin is active. The admin is told and can deactivate the Reference Plugin. Avoid: takeover, conflict mode

Edge-only Feature: An opt-in feature that only works when the Tachyon Server is Tachyon Edge.

Image Facts: What WordPress knows about the site’s images: registered image sizes, attachment metadata and sources, the content width, the uploads URL, and WordPress’s own size calculations. Tachyon Edge Images decides Tachyon arguments from Image Facts and never changes them. Avoid: image data, media info, site state
