Diagramon 3.8.13 给「转换到 drawio」加了一个「用 ELK 重排」开关：勾上之后由 drawio 自带的 ELK layered 引擎重排，回边绕行与边交叉明显减少。

下载

方式 文件 说明
安装版（推荐） Diagramon_3.8.13_x64-setup.exe（约 62.93 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-3.8.13-win-x64.zip（约 70.08 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。
便携版的「检查更新」照常能发现新版，但更新走的是安装包（不会就地替换便携目录）——
要继续用便携形态，就手动下载新的 ZIP 覆盖。

本次亮点

  • 转换时可以换个布局引擎试试：Mermaid 转 drawio 的对话框里多了一个「用 ELK 重排」，勾上就由
    drawio 自带的 ELK layered 引擎排图。回边不再绕大圈、边交叉明显减少，中等规模的流程图比默认的
    dagre 更接近人工调完的样子。这个开关记着你的选择，下次转换不用重新勾。
  • 不勾就和以前完全一样：默认关，走原来那套 dagre，已习惯的画法不受影响。
  • 哪些情况没生效，会如实告诉你：转换记录里会写明这次到底用没用 ELK —— 用了、源文件本来就有
    layout: elk、源文件已经有 config 段（再插会造成重复键，所以跳过）、或者目标不是流程图。
    这些都不静默略过。

修复

  • 从第二个转换开始画布不刷新：连续把两份文件转到 drawio（或 Excalidraw）时，第二个标签页显示的
    还是第一张图；两个画布标签之间来回切换也一样。根因是切文档时把「画布已就绪」清掉了，而承载页的
    就绪信号只在启动时发一次，于是后续的载入指令排在队列里再没发出去。已修（同 3.8.13 一起发）。
  • 关闭画布标签后的残留载荷：关掉最后一个同格式的画布标签时，会顺手清掉那次待用的转换载荷，
    避免下次新建同格式文档被误灌上一次的内容。

说明

  • 「用 ELK 重排」只对 Mermaid → drawio 的流程图有意义：ELK 是 drawio 导入器内部的布局，
    Excalidraw 那条链用的是另一个导入器，不吃这个配置。
  • 它不改变「文档级布局」的语义 —— 预览里选的布局仍然是预览自己的事，转换按这个开关来。

English

Diagramon 3.8.13 adds a "Re-layout with ELK" option when converting to drawio: with it on, drawio's own ELK layered engine arranges the diagram, cutting back-edge detours and edge crossings noticeably.

Downloads

Type File Notes
Installer (recommended) Diagramon_3.8.13_x64-setup.exe (~62.93 MiB) Enables the built-in auto-update; if WebView2 is missing the installer downloads the runtime
Portable (no install) Diagramon-3.8.13-win-x64.zip (~70.08 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.
"Check for updates" still finds new versions, but updating downloads the installer
(it does not replace the portable folder in place) — to stay portable, grab the new ZIP manually.

Highlights

  • Try a different layout engine right in the conversion dialog: Mermaid → drawio now has a
    "Re-layout with ELK" switch. With it on, drawio's own ELK layered engine arranges the diagram —
    back edges stop taking the long way round and edge crossings drop, so medium-sized flowcharts land
    much closer to a hand-tuned result than the default dagre. The switch remembers your choice.
  • Off by default, so nothing changes unless you ask: unchecked, it is exactly the old dagre path.
  • When it does not apply, you are told: the conversion record says what actually happened — applied,
    the source already declared layout: elk, the source already had a config block (injecting another
    would duplicate a key, so it was skipped), or the target is not a flowchart. None of these are silent.

Fixes

  • Canvas did not refresh from the second conversion on: converting two files to drawio (or
    Excalidraw) in a row left the second tab showing the first diagram; switching between two canvas
    tabs had the same problem. The readiness flag was cleared when switching documents, while the host
    page only sends that signal once at startup, so later load commands sat in the queue forever. Fixed
    (shipped together in 3.8.13).
  • Stale pending payload after closing a canvas tab: closing the last canvas tab of a format now also
    drops that pending conversion payload, so a new document of the same format cannot inherit it.

Notes

  • "Re-layout with ELK" only applies to Mermaid → drawio flowcharts: ELK lives inside drawio's
    importer, and the Excalidraw chain uses a different importer that does not read this config.
  • It does not change what document-level layout means — the layout you pick in the preview is still
    the preview's business; conversion follows this switch.

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_3.8.13_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.
