Simplified Chinese Word Splitting

Adds Simplified Chinese word splitting support for the editor and Vim mode for Obsidian.md

增加 Obsidian 内置编辑器的(简体)中文分词支持，使得编辑模式的双击可以选中中文，以及在 Vim 模式下可以按中文分词移动光标

Special Thanks to @fengkx for jieba-wasm module 感谢 @jiyee 实现的Vim分词支持！

注意：从 v1.8.0 开始，默认分词引擎由结巴分词更换为系统自带分词引擎，结巴分词不再是必备组件，若你需要结合 omnisearch 插件使用，或仍需要使用结巴分词提供的更精确的分词结果，以及新词发现、自定义词库功能，请在设置打开选项后，按照弹窗提示进行安装（若系统不提供分词引擎，无论选项是否打开，本插件仍会提示安装结巴分词）

Disclosure 安全声明

[!WARNING] 直接文件系统访问：在桌面端，本插件使用 Node.js fs 模块在 Obsidian Vault API 之外读写文件。这用于将结巴分词 WASM 文件（jieba_rs_wasm_<版本号>.wasm）存储在 Obsidian 的共享 userData 目录中，从而避免在每个库中重复安装：

平台	路径
macOS	~/Library/Application Support/obsidian/jieba_rs_wasm_<版本号>.wasm
Windows	%APPDATA%\obsidian\jieba_rs_wasm_<版本号>.wasm
Linux	~/.config/obsidian/jieba_rs_wasm_<版本号>.wasm

在移动端，该文件通过标准 Obsidian Vault API 存储在库的配置目录（<vault>/.obsidian/jieba_rs_wasm_<版本号>.wasm）中，不涉及直接文件系统访问。

[!WARNING] Direct Filesystem Access: On desktop, this plugin uses the Node.js fs module to read and write files outside of the Obsidian vault API. This is used to store the jieba WASM binary (jieba_rs_wasm_<version>.wasm) in Obsidian's shared userData directory so that it does not need to be duplicated in every vault:

Platform	Path
macOS	~/Library/Application Support/obsidian/jieba_rs_wasm_<version>.wasm
Windows	%APPDATA%\obsidian\jieba_rs_wasm_<version>.wasm
Linux	~/.config/obsidian/jieba_rs_wasm_<version>.wasm

On mobile, the file is stored inside the vault's config directory (<vault>/.obsidian/jieba_rs_wasm_<version>.wasm) using the standard Obsidian vault API, and no direct filesystem access is involved.

Development

Prerequisites

• Node.js 26+ — pinned in mise.toml; the easiest way to provision it is mise. If you manage Node yourself, run corepack enable to activate pnpm.
• pnpm 11.0.9 — sourced from packageManager in package.json via corepack. No global install needed.
• Git with submodule support (any modern version).

One-time setup

# 1. Clone with the cm-view submodule populated.
#    If you already cloned without `--recurse-submodules`, run the second line instead.
git clone --recurse-submodules https://github.com/aidenlx/cm-chs-patch.git
git submodule update --init --recursive

cd cm-chs-patch

# 2. Provision Node 26 + enable corepack (skip if you manage Node yourself).
mise install

# 3. Install dependencies. The `packages/cm-view` workspace package's `prepare`
#    hook builds its `dist/` (the @codemirror/view internal bundle) automatically.
pnpm install

Scripts

Command	Purpose
pnpm dev	Vite watch build to build/; also writes .hotreload for the Obsidian Hot-Reload plugin
pnpm build	Production bundle to build/main.js; the version from package.json is stamped onto manifest.json
pnpm typecheck	tsc --noEmit
pnpm lint	oxlint (pnpm lint:fix to autofix)
pnpm format	oxfmt check (pnpm format:fix to apply)
pnpm release	release-it (maintainers only)

Loading the build into Obsidian

Symlink (or copy) build/ into a test vault as <vault>/.obsidian/plugins/cm-chs-patch, then enable the plugin in Obsidian's Community Plugins settings. With Hot-Reload installed in the same vault, pnpm dev triggers live reloads on rebuild.
