Spell Checker

by Mrbysco

With Spell Checker, typed chat text is compared against a chosen dictionary, and words that are not in the list are marked as misspelled.

What it does

Spell Checker compares what a player types in chat with a selected word list. Any word that does not appear in the list is marked as spelled incorrectly, which gives writers a visual cue while they type messages. Dictionaries for English (UK) and Swiss German are included with the mod, and each is loaded on demand when chosen.

The mod is client-side only, so only the player's own game needs it and a server can run without it. It requires Cloth Config API on every loader, and Fabric API on Fabric. Spell Checker is released under the GNU Lesser General Public License v3.0 only, and its source code and issue tracker are public. Files cover 1.12.2 – 26.2 across Fabric, Forge and NeoForge, with the latest Fabric and NeoForge files built for 26.2 and the latest Forge file built for 1.20.6.

Key features

  1. Chat word comparison

    Words typed in chat are checked against the selected dictionary list as the player writes.

  2. Misspelling marks

    Words missing from the chosen list are flagged as spelled incorrectly, leaving the message text itself unchanged.

  3. Bundled dictionaries

    English (UK) and Swiss German word lists come with the mod, so checking can start without adding any other files.

  4. Personal dictionary

    A personal dictionary is provided and starts empty, letting the player keep words the bundled lists do not contain.

Questions

Does Spell Checker need Cloth Config API?

Yes. Cloth Config API is a required dependency on every loader, and Fabric API is also required when the mod runs on Fabric.

Does a server need Spell Checker installed?

No. The mod is client-side only, so the player installs it and the server does not need it.

Which languages does the mod include?

English (UK) and Swiss German dictionaries are bundled. The personal dictionary starts empty, and the player can add words to it.
