Vue is an experimental port of TeXmacs 1.2.5 to Webassembly with a new (immediate mode) GUI (Vue), a new icon set, support for Opentype Math fonts, powered by S7 Scheme (instead of Guile). Fully functional. More info at https://github.com/mgubi/texmacs/tree/wip_wasm_vue

Kinda bad choice of name, when it comes to finding documentation online. Everyone will find Vuejs things when searching.
