PROPER is a Semantic Texteditor based on HTML's
contenteditable attribute. It's being developed in the context of Substance, a data driven document authoring engine.
The goal is to output proper semantic HTML by restricting the set of possible tags. When pasting content, the markup is stripped.
Solves various issues and produces cleaner and more semantically correct html.
Solves a number of Firefox related issues and adds native support for
Recognition of command states. Support for keybindings.
