One Markdown is a simple and fast editor that supports plain text, Markdown, and Textbundle. It fully supports the CommonMark standard and GitHub Flavored Markdown (GFM). The same basic library is used for syntax highlighting and parsing into HTML.
In the editing and preview mode, the edited content and the previewed content can now be accurately aligned, and the performance is greatly improved due to the use of WKWebView. The tool supports the display of images in the editor, the creation of editable Textbundle documents, and the use of mathematical formulas, Echarts, and mermaid.
