TeX Type

A browser extension that converts commands (some TeX) in textboxes to unicode as one types. It is intended particularly for inserting simple mathematics in chats without native support. Ignore the cheesy name.

To bundle the extension, run nix build in the root of this repository. The result will be available at result/tex-type.zip.

'Supported' Websites

The extension should work with <input type="text">, <textarea> and contenteditable elements, but it can confuse and be confused by custom event handlers. It works on the following, to a certain extent:

Adobe Connect (last time I checked)
Pronto
Skype, but only halfway

Configuration

Click on the extension icon in the toolbar or in its extensions menu to open the options page. This page can also be accessed from the extensions manager in Firefox, in Chromium-based browsers, etc.

Alternative

Font ligatures could be used instead, but then all readers would have to install such a font, whereas only the writer requires this extension.

Development

demo.html provides a textbox with the extension logic attached.

{bold,{sub,super}script}.py are hacky, half-finished scripts that generate unicode-maps-*.js from UnicodeData.txt. More will come.

The extension can be tested by temporarily installing it in Firefox or by installing it in Chromium-based browsers.
