mathtex-editor-core

mathtex-editor-core is the framework-neutral engine behind mathtex-editor, a structural WYSIWYG math editor powered by mathtex.

The crate owns the editable math tree, caret, selection, and editing state. Applications send Commands to an Editor and implement the Host trait to connect typesetting, repainting, content changes, and boundary events to their UI environment.

Features

• Structural editing for fractions, scripts, radicals, delimiters, accents, matrices, large operators, under/over constructs, and math styles
• Keyboard and pointer navigation across nested structures
• Selection, structural clipboard fragments, and host-managed undo/redo entries
• LaTeX export with source spans matched against mathtex-ir layout output
• Renderer-neutral caret, selection, placeholder, and contextual-menu geometry
• A host boundary that works with native, web, or framework-specific front ends

Architecture

Command -> Editor -> structural tree -> LaTeX + source spans
                                      -> Host::typeset -> mathtex IR
                                      -> RenderOutput

The model is the canonical document. LaTeX is generated as a render and interchange output; this crate does not parse arbitrary LaTeX back into editor state.

For the default browser-style keyboard mapping and backslash command catalog, use mathtex-editor-keymap.
