SNLATEX Markdown Editor

Math Syntax

Inline math:

$E = mc^2$
\(E = mc^2\)

a^2 + b^2 = c^2
$$

\[
a^2 + b^2 = c^2
\]

Repository Layout

• ext.json is the Standard Notes extension manifest.
• com.sncommunity.markdown-basic/app/ contains the source editor component.
• com.sncommunity.markdown-basic/dist/ contains the built assets served by GitHub Pages.
• com.sncommunity.markdown-basic/package.json contains the build dependencies and scripts.

Development

From the plugin package directory:

cd com.sncommunity.markdown-basic
npm install
npm run build

The built files in dist/ are intentionally committed because Standard Notes loads the hosted component directly from GitHub Pages.
