Cron job board: schedules local scripts or dsh session tasks (fresh or pinned sessions) by cron expression, with centralized environment-variable management, run logs, and concurrency and timeout control.
Install
# from npm (prebuilt)
dsh plugin --profile web add @mzzsfy/dsh-cron-board
# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)
dsh plugin --profile web add github:mzzsfy/dsh-plugin#path:/packages/dsh-cron-board
Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time — pnpm blocks those until you allow them, so an install can stop with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED or ERR_PNPM_IGNORED_BUILDS; dsh prints the exact key to add under allowBuilds in your profile’s pnpm-workspace.yaml, and the install works on the next run. Allowing a build is a trust decision: only install sources you trust, and pin a commit (github:owner/repo#sha).

轻量级定时任务看板 dsh 插件:环境变量集中管理 + 定时任务(cron)调度,执行体支持两类——本地脚本(dsh 宿主进程内 spawn)与 dsh 会话任务(定时向 dsh 会话投递任务,投递即终态,支持「每次新建会话」或「固定同一会话」)。
设计文档见仓库 docs/progress/debug-fix-cron-board-delivery-semantics.md(近期语义收敛决策记录)。
功能
- 看板:任务卡片列表(状态色/下次触发相对时间/启停开关/立即运行/编辑/删除),新建编辑模态为调度构建器布局:类型/会话模式/调度频率统一分段组件,结构化频率(每天/每周/工作日/固定间隔)自动生成表达式(反解不出即自定义手输),即将执行时刻 chips 为服务端实时预览
- 环境变量:集中管理,值打码展示,多值(同名展开笛卡尔积,组合数超出 20 截断并告警),dotenv 文本导入(预览/追加/覆盖)与导出
- 会话任务:投递即终态(crontab 语义,执行状态归会话本身);fresh 每次新建会话;pinned 固定会话(忙时跳过,会话被删除或归档自动重建并回写,首跑自动绑定);按 workdir 自动挂载宿主分组,界面分组内可见;执行预设可选(Agent Preset,缺省跟随宿主默认,dsh-im 同构)
- 调度:croner 解析,停机期间错过不补跑(misfire 即跳过),孤儿运行恢复,全局与任务级并发闸门;shell 任务超时收尾(会话任务无超时语义);单次运行开关(runOnce,任意一次真实运行入队后自动停用任务)
- 时区:cron 表达式支持内联时区后缀
T±N(整数小时,如0 9 * * *T+8表示东八区 9 点,范围 -12 至 +14,T+0即 UTC);构建器提供时区行写入后缀,新建任务默认固化设备时区偏移;无后缀表达式按宿主进程系统时区调度(crontab 惯例),摘要与运行记录按任务所用时区展示;固定偏移不随夏令时变化,半时区设备的设备偏移就近取整 - 日志:每任务每运行独立日志文件,面板查看与清空,按任务保留条数裁剪(按文件修改时间)
路由
前缀 /api/cron-board(envs / jobs / runs / status / cron/preview / agent-presets),REST 风格,中文业务错误透传。
界面挂载
挂载走宿主官方契约(main 全局面板插槽 / sidebar.panellist 侧栏面板行 / better-sidebar 服务),不刮宿主 DOM,宿主 UI 变动由契约消化:
- 默认:全局面板。看板以同 id 注册 main keyed 条目(中央面板)+ sidebar.panellist 条目(侧栏「新会话」下方面板行);点击面板行由宿主
layout.selectPanel切换中央区,会话保持不动;点击会话行或新会话即切回会话(官方路径) - 手动移入:设置>插件 页「定时任务」卡片(官方 PluginCard 形制:折叠卡壳,cb-pc 镜像)提供「看板移入 better-sidebar 侧边栏」开关;开启即注册扩展槽 tab 并卸载全局面板
- 不自动回退:移入后页签关闭/类型禁用均不再自动返回;把开关关掉即回到全局面板形态(轮询感知,约一个 tick 周期内生效)
- 开关可用性:已装载 better-sidebar 时可切换;未装载时开关呈禁用态仅展示(保持全局面板,无副作用)
配置
设置页>插件 页「定时任务」卡片(cron-board 命名空间),各项均即时生效:sidebarTab 经卡片开关写入;其余项经配置文件或设置接口修改。
| 配置项 | 说明 | 默认值 |
|---|---|---|
tickSeconds |
调度轮询周期(秒,最小 5),变更后自动按新周期重建定时器 | 30 |
maxConcurrent |
全局同时运行的执行单元上限 | 2 |
logKeepPerJob |
每任务保留的运行日志份数(超出按文件修改时间裁剪) | 200 |
maskEnvInPrompt |
会话任务投递文本中环境变量值打码 | 关 |
sidebarTab |
看板移入 better-sidebar 侧边栏(需已装载;关闭时以侧栏面板行 + 全局面板呈现) | 关 |
依赖
croner:cron 表达式解析与触发点计算- 宿主服务:settings / timer(软依赖)、webServer;sessionController 在 apply 内探测(缺失时打日志干净禁用,插件整体不激活,含脚本任务;0.1.1-rc.2 及更早版本无此服务)
开发
node scripts/dev-link.mjs dsh-cron-board # 挂载工作副本到 profile
cd packages/dsh-cron-board
node --test "test/*.test.mjs" # 测试
注意:插件新增进入 profile bundles(dsh plugin add)后需 dsh 重启一次完成首装载;此后工作副本改动经 dev-link HMR 热重载。
dsh 版本兼容
三版本全部通过:cron 看板渲染与启停、与侧边栏联动(侧栏标签页形态)、激活 live。0.1.6 新侧栏标签页系统下联动开关双态均验证通过。
