Mermaid Graphical Editor Extension

Mermaidの編集をGUIサポートするエディタビューを表示することができます。現在、フローチャートとシーケンス図、クラス図、ER図の一部の編集のみGUIサポートに対応しています。

GUIサポートで対応していない記述(フローチャートのDirectionやSubgraphsなど)は、Mermaidコードの方を直接編集することで反映されます。

補足:
このExtensionは、Mermaidがgithubで正式にサポートされたのを受けて、issueなどでのMermaid利用の敷居を下げることを目的として作成していますが、githubでのみに限定する必要もないと考え、どのページでも利用可能にしています。

You can display an editor view with GUI support for Mermaid editing. Currently, GUI support is supported only for editing some parts of the flowchart and sequence, class diagram, and er diagram.

Descriptions not supported by GUI support (e.g., Direction and Subgraphs in flowcharts) will be reflected by editing the Mermaid code directly.

Supplement:
This extension was created with the aim of lowering the threshold for using Mermaid in issues after Mermaid was officially supported on github, but we believe that it does not need to be limited to github only, so we make it available on any page.
