This evidence comes from the upstream catalog. This site has not installed, run, or security-reviewed the plugin.

Install

Start with a prompt that asks an agent to review the GitHub repository and source. Switch to the command if you want to install it yourself.

Copy this prompt into DSH, Codex, or another agent and ask it to review the GitHub repository and source first.

Do not install or run any commands yet. Read this plugin's GitHub repository, README, and relevant source code. Then answer the questions below clearly and directly so I can decide whether it fits my needs:

1. What is this plugin, and what problem does it solve?
2. Who is it for, and what are its typical use cases?
3. How is it used after installation? Include one minimal example.
4. What known limitations or privacy, security, compatibility, or maintenance risks does it have?
5. Give a clear recommendation: recommend, conditionally recommend, or do not recommend, with reasons.

Distinguish statements documented by the repository, inferences from source code, and unknowns. If evidence is insufficient, say so explicitly. Do not guess or simply repeat the README.

dsh-chat-width

调宽 dsh 网页会话区的聊天内容宽度。dsh 原生把会话文字列限制在 748px,在大屏上左右浪费大量空间;本插件通过客户端 CSS 把 --dsh-chat-content-width 覆盖为 1040px(默认值,可调)。

输入框、底部工具栏等宽度由同一变量派生(calc(var(--dsh-chat-content-width) + 32px)),会自动跟着变宽。

调整宽度

两种方式,任选其一:

1. 拖拽把手(推荐):会话文字列右缘(垂直中点)有一个细长的竖向把手,鼠标按住左右拖动即可实时调整宽度,松开自动记忆。双击把手恢复默认值 1040px。把手的半透明样式与主题融合,悬停/拖动时高亮。 2. 控制台(F12):

``js __setChatWidth(960) // 任意值,范围 520~2400,立即生效 __setChatWidth(1040) // 恢复默认 ``

选择会记忆到 localStorage(键 dsh_chat_width),下次打开页面仍生效。

安装

方式一:插件市场(推荐) —— 在 dsh 网页的设置 → 插件市场中搜索 dsh-chat-width,一键安装。

方式二:命令行(dsh >= 0.1.0-rc.7):

dsh plugin --profile web add github:764475881/dsh-chat-width

方式三:本地开发(link)

# 在 web profile 目录(~/.dsh/profiles/web)下
pnpm add link:/home/miku/dsh-chat-width
# 并在该 profile 的 package.json 中把 "dsh-chat-width" 加入 dsh.profile.bundles
# 然后重启 dsh web(新增 bundle 需重启生效)

卸载同理:从 package.json 的 dependencies 与 bundles 移除,pnpm install,重启。

原理

  • 服务端占位 lib/index.js:空 apply,仅让 loader 行可挂载。
  • 客户端 lib/client.js:注册为 DSH 客户端模块,注入 <style> 覆盖:

- .wSkVaW_root.wSkVaW_root(当前 dsh 版本的会话根元素类名) - [data-phase][data-phase](版本无关兜底选择器,特异性 (0,2,0) 压过 dsh 自带定义)

  • 拖拽把手 .dsh-cw-handle 绝对定位锚定在文字列右缘:right: calc((100% - var(--dsh-chat-content-width)) / 2 - 7px),宽度变化由 CSS 变量实时驱动,无需 JS 计算位置;pointer 事件 + setPointerCapture 完成拖拽,松手写入 localStorage。
  • 跟手映射:文字列居中布局下右缘位移 = 宽度变化的一半,因此拖拽时宽度按指针位移的 变化,把手(锚定右缘)才能 1:1 跟随鼠标,且列始终居中、松手无回弹。
  • 会话根元素可能在 boot 后才挂载(hero 阶段),插件用 MutationObserver 跟随根元素出现/切换并挂载把手。

详细设计决策见 [docs/DESIGN.md](docs/DESIGN.md)。

开发

node --check lib/client.js

改完 lib/client.js 后,运行中的 dsh 会在约 1 秒内通过 HMR 热替换(无需重启)。
