Diagramon 3.12.4 让「格式化源码」从一个空按钮变成真正可用的排版工具。

下载

方式 文件 说明
安装版（推荐） Diagramon_3.12.4_x64-setup.exe（约 62.26 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-3.12.4-win-x64.zip（约 70.37 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

  • 「格式化」按钮 / Shift+Alt+F 现在真的重排源码，不再只是抹掉行尾空格：
    • Mermaid：subgraph…end、序列图的 loop/alt/opt/par/rect/critical/break/box…end、
      else/and/option、class / state / er 的花括号，统一缩进到 4 空格；
    • Graphviz DOT：按词法重排 —— 一行一条语句、属性表内联、子图缩进，一行式
      digraph G{a->b;b->c} 会展开成可读的多行；
    • D2：花括号层级统一缩进到 2 空格。
  • 只动空白，不动语义：字符串、HTML 标签、跨行引号标签、Mermaid 的 YAML frontmatter、
    D2 的 |md 块字符串都逐字节保留；DOT 的注释与 # 行也原样搬运。
  • 不假装修了一遍：源码本来就规范时，状态栏会如实说「已是规范格式」，不会标脏。
  • 可撤销：整块替换走编辑器的正常事务，Ctrl+Z 能退回格式化之前；落盘仍跟随你的自动保存设置。

修复

  • 「格式化源码」此前没有真正实现：按钮与 Shift+Alt+F 都只做了一次行尾空白清理，
    多数文档点下去等于没反应（菜单里印着功能，实际是空壳）。本版补上了 Rust 侧的格式器，
    并把它接进按钮、快捷键与命令面板。

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_3.12.4_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。

Diagramon 3.12.4 turns "Format source" from an empty button into a real formatter.

Downloads

Type File Notes
Installer (recommended) Diagramon_3.12.4_x64-setup.exe (~62.26 MiB) Enables the built-in auto-update; if WebView2 is missing the installer downloads the runtime
Portable (no install) Diagramon-3.12.4-win-x64.zip (~70.37 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

  • The Format button / Shift+Alt+F now actually reformats the source, no longer just trimming
    trailing whitespace:
    • Mermaid: subgraph…end, sequence loop/alt/opt/par/rect/critical/break/box…end,
      else/and/option, and class / state / er braces are all indented to 4 spaces;
    • Graphviz DOT: lexer-level layout — one statement per line, attribute lists inlined,
      subgraphs indented; a one-liner like digraph G{a->b;b->c} expands into readable lines;
    • D2: brace levels are indented to 2 spaces.
  • Whitespace only, semantics untouched: strings, HTML labels, multi-line quoted labels,
    Mermaid YAML frontmatter and D2 |md block strings are preserved byte for byte; DOT comments
    and # lines are carried over verbatim.
  • No fake "formatted": when the source is already canonical, the status bar says so and the
    document is not marked dirty.
  • Undoable: the whole-document replacement goes through the editor's normal transaction, so
    Ctrl+Z returns to the pre-format text; saving still follows your auto-save setting.

Fixes

  • "Format source" was never really implemented: the button and Shift+Alt+F only trimmed
    trailing whitespace, so on most documents they did nothing. This release adds the Rust-side
    formatter and wires it to the button, the shortcut and the command palette.

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_3.12.4_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.
