中文

Diagramon 3.9.1 是对 3.9.0 的修正：把「语法错误定位到行列」真正做通。

下载

方式 文件 说明
安装版（推荐） Diagramon_3.9.1_x64-setup.exe（约 62.08 MiB） 装完可用内置自动更新；缺 WebView2 时安装器会自动下载运行时
便携版（免安装） Diagramon-3.9.1-win-x64.zip（约 70.14 MB） 解压到任意位置，双击 diagramon.exe 即用；卸载 = 删文件夹

便携版说明：包里是 diagramon.exe + WebView2Loader.dll + ui\ + assets\，必须放在一起
（ui\ 与 assets\ 是从磁盘读的，不在 exe 里）。它不依赖额外要装的东西：不需要 Node.js、
不需要 Chrome、不需要 VC++ 运行库（exe 已静态链接 CRT），只需要 Windows 10/11 自带的 WebView2 运行时。

修复

  • 问题面板现在真的显示「行 + 列」：3.9.0 里引擎报出的精确列号虽然采到了，但面板只显示行、点击也只跳到行首。
  • 同一行不再被粗略结论盖住：以前如果行扫描器在同一行也报了问题（比如「括号没有闭合」），
    引擎那条带真实行列的精确结果会被丢掉。现在改为引擎优先——同一行保留引擎的精确报错，带行列。
  • 点击问题按列跳转：点问题面板里的条目，光标会落到 行:列，不只是行首。
  • 其它行保持原样：行扫描器独有的问题照报，不回归；合法文档依旧不误报。

Diagramon 3.9.1 fixes 3.9.0: syntax errors now really show and jump to line + column.

Downloads

Type File Notes
Installer (recommended) Diagramon_3.9.1_x64-setup.exe (~62.08 MiB) Enables the built-in auto-update; if WebView2 is missing the installer downloads the runtime
Portable (no install) Diagramon-3.9.1-win-x64.zip (~70.14 MB) Unzip anywhere and run diagramon.exe; uninstall = delete the folder

About the portable build: it ships diagramon.exe + WebView2Loader.dll + ui\ + assets\, and those
must stay together (the ui\ and assets\ trees are read from disk, not embedded in the exe).
It needs nothing extra installed: no Node.js, no Chrome, no VC++ redistributable (the CRT is
statically linked) — only the system WebView2 runtime that comes with Windows 10/11.

Fixes

  • The problems panel now really shows line + column. In 3.9.0 the exact column reported by the engine was
    collected but never displayed, and clicking only jumped to the start of the line.
  • A rough same-line result no longer hides the precise one. Previously, if the line scanner also reported
    that line (e.g. "bracket not closed"), the engine's precise result with real line/column was dropped.
    The engine now wins on the same line.
  • Clicking an issue jumps to line:column, not just the line start.
  • Other lines unchanged: scanner-only findings are still reported, and valid documents are still not flagged.

About Diagramon

Diagramon is a local-first multi-format diagram editor: Mermaid, Graphviz DOT, drawio and Excalidraw
can all be edited with live preview, with AI assistance for generation, review and image recognition.
Rendering and validation work with no network at all — code or images reach a model only when you
actively use AI, and then only the endpoint you chose.

Requirements

  • Windows 10 / 11 64-bit
  • WebView2 runtime (normally pre-installed on Windows 10/11; the installer downloads it if missing)
  • No Node.js, Chrome or VC++ redistributable needed — the canvas runtimes and front-end assets all
    ship inside the installer

Install and update

Download Diagramon_3.9.1_x64-setup.exe and run it. Users on an older version
will be offered this release via Help → Check for updates (the update package is this same
installer; its signature is in latest.json).

This installer is not yet Authenticode-signed, so Windows SmartScreen may show a warning.
