中文

Diagramon 3.13.2 是一个修复版本：只改预览的渲染调度，解决"源码是对的却不渲染"。

下载

方式 文件 说明
安装版（推荐） Diagramon_3.13.2_x64-setup.exe（约 62.29 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-3.13.2-win-x64.zip（约 70.41 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。

修复

  • 改完源码有时不渲染，切一下视图模式才出来。预览的渲染原先靠 60ms 防抖直接触发引擎，
    而一次 ELK 布局常常上百毫秒 —— 连续敲字就会叠出多个并发的引擎渲染。mermaid / graphviz / D2
    都不是并发安全的（mermaid.render() 用全局配置与共享的 DOM 暂存节点），叠在一起那一次可能
    什么都不出；而且被后来的渲染顶掉的那次改动不会再重来，于是停在空白，直到切一次视图模式
    （那会再排一次渲染）。现在：① 渲染入口串行化，同一时刻只有一轮在跑；② 跑的过程中又收到改动，
    就跑完再补一次（照最新正文画，不会挂旧图）。await DGM.preview.render() 的语义也保留了 ——
    忙时等的是"正在跑的那一轮"，仍然保证回来时已画到最新。

关于 Diagramon

Diagramon 是一款本地优先的多格式图表编辑器：Mermaid / Graphviz DOT / drawio / Excalidraw
都可编辑并实时预览，AI 可辅助生成、评审与识图。渲染与校验不联网也能用 ——
只有你主动使用 AI 时，相关代码或图片才会发往你选择的上游。

系统要求

  • Windows 10 / 11 64 位
  • WebView2 运行时（Windows 10/11 通常已预装；缺失时安装器会现场下载）
  • 不需要 Node.js、Chrome 或 VC++ 运行库 —— 画布运行时与前端资源都随包分发

安装与更新

下载 Diagramon_3.13.2_x64-setup.exe 直接安装。已装旧版的用户可在
帮助 → 检查更新 里收到本版本（更新包即本安装包，签名见 latest.json）。

本安装包尚未做 Authenticode 代码签名，Windows SmartScreen 可能给出提示。

English

Diagramon 3.13.2 is a bug-fix release: it only changes how the preview schedules rendering,
fixing the case where valid source would not draw.

Downloads

Type File Notes
Installer (recommended) Diagramon_3.13.2_x64-setup.exe (~62.29 MiB) Enables the built-in auto-update; if WebView2 is missing the installer downloads the runtime
Portable (no install) Diagramon-3.13.2-win-x64.zip (~70.41 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.

Fixes

  • After editing the source, the diagram sometimes would not render until you switched the view mode.
    The preview used to fire the engine straight from a 60 ms debounce, while a single ELK layout often
    takes hundreds of milliseconds — so continuous typing stacked several concurrent engine renders.
    mermaid / graphviz / D2 are not concurrency-safe (mermaid.render() uses global config and a shared
    DOM scratch node), a stacked render can produce nothing at all, and the edit that got superseded
    was never retried — leaving a blank stage until a view-mode switch scheduled one more render.
    Now: (1) the render entry is serialized, only one round runs at a time; (2) if an edit arrives while
    rendering, one more round is queued after it and draws the latest source (never a stale diagram).
    await DGM.preview.render() keeps its meaning too — when busy it awaits the in-flight round, so it
    still resolves once the preview is up to date.

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_3.13.2_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.
