Modules

ast

Math AST. A formula is a Row (horizontal sequence of nodes); every editable slot in a structure node is itself a Row, so the cursor can always be described as (path into nested rows, column in that row).

complete

Tab completion for \commands.

editor

Structural editing model. The cursor is a path of (node index, field) pairs from the root row plus a column inside the innermost row — the usual WYSIWYG model for math insets.

from_latex

Read LaTeX math back into the AST — the reverse of output/latex. Two promises, in order:

glyphs

The structural glyph constants — the drawing vocabulary that is not a spelling table: nothing here maps a \name to a meaning or classifies families; each constant is one canonical glyph with one structural role. The spelling/classification layer lives under symbols; render and parse spell their pictures with these names.

input

Host-independent keymap: the single place where keystrokes are mapped onto editor operations. The TUI (crossterm) and the wasm bindings (DOM KeyboardEvent) only translate their native events into Key and dispatch through Editor::input, so the two frontends cannot drift apart.

output

AST -> markup serializers (the AA form itself lives in render/parse).

parse

AA -> AST parser: the inverse of render.rs on canonical output.

render

2D layout engine: AST -> rectangular block of chars with a baseline.

symbols

Every table the format rests on, one concern per file:
