edid-editor

Client-side EDID viewer and editor.

The project is a continuation of goedid.

The project has two layers:

• edidts (packages/edidts/) — the core: a framework-agnostic TypeScript library (an npm workspace package) that owns all EDID, CTA-861, and DisplayID decoding and encoding. The data model is byte-oriented: each format class parses a Uint8Array via a static decode() and serializes back via a static encode(). EEDID is the top-level container, EDID is the 128-byte base block, and the per-spec extension types (CTA-861, DisplayID, VTB, Block Map) live alongside.
• Vue app (src/) — the editor UI built on top of the library. View components mirror the data model, mutations bind directly to the reactive EEDID tree, and a single computed re-encodes the bytes after every edit.

• Being able to visualise EDID, CEA and DisplayID
• Being able to edit key aspects of EDID, CEA and DisplayID

npm run dev      # start the Vite development server
npm run build    # type-check with vue-tsc and build for production
npm run preview  # preview the production build locally

The edidts package has its own scripts, run from packages/edidts/:

npm run build  # type-check with tsc and build with Vite
npx vitest run # run the library's test suite

npm test            # run the Vue app + edidts test suites (in-module fixtures only)
npm run test:corpus # run the edidts corpus tests against the linuxhw/EDID collection

The corpus run exercises the parser against the ~175k real EDIDs in linuxhw/EDID. That collection is not tracked in this repo — clone it locally (one-time, ~5 GB) where the loader reads from:

git clone --depth=1 https://github.com/linuxhw/EDID.git packages/edidts/tests/fixtures-linuxhw

The packages/edidts/tests/fixtures-linuxhw/ directory (and a root tests/ checkout) is gitignored. If the directory is absent the loader silently skips it and falls back to the in-module fixtures, so CI and fresh clones see no change. To run a deterministic sample instead of the full corpus, set EDID_FIXTURE_LIMIT (see packages/edidts/README.md for details).
