bind changable markdown var to reveal

[superiums]

i'm trying to make a markdown editor for reveal using svelte. seems difficult to parse dynamic markdown text to reveal. the buildin markdown plugin only accept const/fixed markdown text under template, or text from a remote md file.

so i customized the buildin plugin to receive markdown text from a var. but another problem comes. there's only an init interface in plugins, never a update interface provided.

is it possible to receive markdown text dynamicly while user typed?
