meta — Multi-Repo Orchestration

meta — 多仓库编排工具

meta

solves the mono-repo vs. many-repos dilemma by saying "both". A meta repo is a thin git repository that contains a

.meta

config file listing child repositories;

meta

commands then fan out across all those children at once. Unlike git submodules or subtree, child repos remain independent first-class git repos — different teams can clone just the slice they need. The plugin architecture (commander.js,

meta-*

npm packages) means you can extend meta to wrap any CLI tool, not just git.

meta

通过「两者兼顾」的方式解决了单仓库与多仓库的两难困境。元仓库（meta repo）是一个轻量的Git仓库，包含一个

.meta

配置文件，列出所有子仓库；

meta

命令可以同时作用于所有这些子仓库。与Git子模块或subtree不同，子仓库始终是独立的一等Git仓库——不同团队可以只克隆他们需要的部分。其插件架构（基于commander.js，

meta-*

npm包）意味着你可以扩展meta来封装任何CLI工具，而不仅仅是Git。

When to use this skill

何时使用本技能

Trigger this skill when the user:

Wants to clone an entire multi-repo project in one command
Needs to run a git command (status, checkout, pull) across all child repos
Wants to run an arbitrary shell command against every repo (
```
meta exec
```
)
Is migrating a monorepo into many repos using
```
meta project migrate
```
Needs to run
```
npm install
```
or
```
yarn
```
across all repos at once
Asks how to add or import a child repo into a meta project
Wants to onboard a new developer to a multi-repo architecture
Needs to filter commands to a subset of repos (
```
--include-only
```
)

Do NOT trigger this skill for:

Single-repo builds managed with Turborepo or Nx — use the
```
monorepo-management
```
skill
Docker/container orchestration even when containers span many repos

当用户有以下需求时触发本技能：

想要用一条命令克隆整个多仓库项目
需要在所有子仓库中执行Git命令（status、checkout、pull）
想要在每个仓库中执行任意shell命令（
```
meta exec
```
）
正在使用
```
meta project migrate
```
将单仓库拆分为多仓库
需要在所有仓库中一次性执行
```
npm install
```
或
```
yarn
```
询问如何在元项目中添加或导入子仓库
想要为新开发者完成多仓库架构的入职配置
需要将命令限定作用于部分仓库（使用
```
--include-only
```
参数）

请勿在以下场景触发本技能：

使用Turborepo或Nx管理的单仓库构建——请使用
```
monorepo-management
```
技能
跨多仓库的Docker/容器编排

Setup & authentication

配置与认证

bash

undefined

bash

undefined

Install meta globally

全局安装meta

npm i -g meta

Initialise a brand-new meta repo

初始化一个全新的元仓库

mkdir my-meta-repo && cd my-meta-repo && git init meta init

Add child repos

添加子仓库

meta project create services/api git@github.com:yourorg/api.git meta project import packages/ui git@github.com:yourorg/ui.git

Clone an existing meta repo (clones meta repo + all children)

克隆已有的元仓库（会克隆元仓库及所有子仓库）

meta git clone git@github.com:yourorg/my-meta-repo.git


The `.meta` file (JSON) is the only config that meta requires. It is committed
to the meta repo and checked out with the meta repo itself. Child directories
are automatically added to `.gitignore` — they are not nested inside the meta
repo's git object store.

```json
{
  "projects": {
    "services/api": "git@github.com:yourorg/api.git",
    "packages/ui":  "git@github.com:yourorg/ui.git"
  }
}

meta git clone git@github.com:yourorg/my-meta-repo.git


`.meta`文件（JSON格式）是meta唯一需要的配置文件。它会被提交到元仓库中，并随元仓库一起检出。子仓库目录会自动被添加到`.gitignore`中——它们不会被嵌套在元仓库的Git对象存储中。

```json
{
  "projects": {
    "services/api": "git@github.com:yourorg/api.git",
    "packages/ui":  "git@github.com:yourorg/ui.git"
  }
}

Core concepts

核心概念

The meta repo vs. child repos

元仓库 vs 子仓库

The meta repo is a regular git repository that contains only orchestration artifacts: the

.meta

config, a root

package.json

(optional), a

docker-compose.yml

, a

Makefile

, etc. Child repos live at the paths listed in

.meta

and are independent git repos — each with its own remote, branches, and history. The meta repo never tracks child files.

元仓库是一个普通的Git仓库，仅包含编排相关的文件：

.meta

配置文件、根目录的

package.json

（可选）、

docker-compose.yml

、

Makefile

等。子仓库位于

.meta

中列出的路径下，是独立的Git仓库——每个都有自己的远程仓库、分支和提交历史。元仓库永远不会追踪子仓库的文件。

.meta config file

.meta配置文件

The

.meta

file is plain JSON with a single

projects

map from local path to git remote URL. Editing it manually is valid;

meta project create/import

edits it for you and also updates

.gitignore

. Do not commit child directories.

.meta

文件是纯JSON格式，包含一个

projects

映射，键是本地路径，值是Git远程仓库URL。你可以手动编辑它；

meta project create/import

命令会自动帮你编辑该文件，并更新

.gitignore

。请勿提交子仓库目录。

Plugin architecture

插件架构

Every

meta

sub-command is contributed by a plugin — an npm package named

meta-<plugin>

. Core plugins ship with meta:

meta-init

meta-project

meta-git

meta-exec

meta-npm

meta-yarn

. Install third-party plugins globally or as devDependencies in the meta repo.

每个

meta

子命令都由插件提供——这些是名为

meta-<plugin>

的npm包。核心插件随meta一起发布：

meta-init

、

meta-project

、

meta-git

、

meta-exec

、

meta-npm

、

meta-yarn

。你可以全局安装第三方插件，或作为元仓库的devDependencies安装。

loop under the hood

底层的loop机制

meta is built on loop, which provides

--include-only

and

--exclude

filtering so commands can target a subset of child repos. This is useful for running commands only on repos that have changed or belong to a particular team.

meta基于loop构建，它提供

--include-only

和

--exclude

过滤参数，让命令可以只作用于部分子仓库。这在仅对已变更或属于特定团队的仓库执行命令时非常有用。

Common tasks

常见任务

1. Clone a meta project (new developer onboarding)

1. 克隆元项目（新开发者入职）

bash

meta git clone git@github.com:yourorg/my-meta-repo.git
cd my-meta-repo

bash

meta git clone git@github.com:yourorg/my-meta-repo.git
cd my-meta-repo

All child repos are now cloned into their configured paths

所有子仓库现在已克隆到配置好的路径中

undefined

undefined

2. Run a git command across all repos

2. 在所有仓库中执行Git命令

bash

meta git status          # status in every child repo
meta git pull            # pull latest in every child repo
meta git checkout main   # check out main in every child repo

bash

meta git status          # 查看所有子仓库的状态
meta git pull            # 拉取所有子仓库的最新代码
meta git checkout main   # 在所有子仓库中切换到main分支

3. Execute an arbitrary shell command

3. 执行任意shell命令

bash

undefined

bash

undefined

Run any shell command in every child repo

在所有子仓库中执行任意shell命令

meta exec "npm ci" meta exec "npm run build" --parallel # run in parallel meta exec "echo $(pwd)" # use shell expansions (escape $)

undefined

meta exec "npm ci" meta exec "npm run build" --parallel # 并行执行 meta exec "echo $(pwd)" # 使用shell扩展（注意转义$）

undefined

4. Run npm/yarn commands across all repos

4. 在所有仓库中执行npm/yarn命令

bash

meta npm install         # npm install in every child repo
meta npm run test        # run the test script everywhere
meta yarn install        # yarn equivalent

bash

meta npm install         # 在所有子仓库中执行npm install
meta npm run test        # 在所有仓库中运行测试脚本
meta yarn install        # yarn的等效命令

5. Add or import a child repo

5. 添加或导入子仓库

bash

undefined

bash

undefined

Create a new repo entry (registers remote, does NOT init a new git repo)

创建一个新的仓库条目（注册远程仓库，不会初始化新的Git仓库）

meta project create services/worker git@github.com:yourorg/worker.git

Import an existing repo that is already cloned locally

导入已在本地克隆的现有仓库

meta project import packages/shared git@github.com:yourorg/shared.git


Both commands update `.meta` and `.gitignore` automatically.

meta project import packages/shared git@github.com:yourorg/shared.git


这两个命令都会自动更新`.meta`和`.gitignore`。

6. Migrate a monorepo to a meta repo

6. 将单仓库迁移为元仓库

bash

cd existing-monorepo
meta init

bash

cd existing-monorepo
meta init

For each package to extract:

对每个要提取的包执行：

meta project migrate packages/auth git@github.com:yourorg/auth.git meta project migrate packages/api git@github.com:yourorg/api.git


`meta project migrate` moves the directory out of the monorepo's git history
into a fresh repo at the given remote URL, then registers it in `.meta`.

meta project migrate packages/auth git@github.com:yourorg/auth.git meta project migrate packages/api git@github.com:yourorg/api.git


`meta project migrate`会将目录从单仓库的Git历史中移出，放到指定远程URL的新仓库中，然后将其注册到`.meta`中。

7. Target a subset of repos

7. 仅针对部分仓库执行命令

bash

undefined

bash

undefined

Only run in specific repos

仅在特定仓库中执行

meta git status --include-only services/api,services/worker

Exclude a repo

排除某个仓库

meta exec "npm run lint" --exclude packages/legacy

undefined

meta exec "npm run lint" --exclude packages/legacy

undefined

8. Update child repos after pulling new meta config

8. 拉取新的元配置后更新子仓库

bash

undefined

bash

undefined

After someone else added a new child repo to .meta:

当其他人向.meta中添加了新的子仓库后：

git pull origin main meta git update # clones any new repos listed in .meta

---

git pull origin main meta git update # 克隆.meta中列出的所有新仓库

---

Error handling

错误处理

Error	Cause	Resolution
`fatal: destination path already exists`	Child repo directory exists but is not registered in `.meta`	Delete the directory or run `meta project import` to register it
Command runs in meta root but not in children	`.meta` projects map may be empty or path is wrong	Check `.meta` contents; ensure paths match actual directory layout
`meta: command not found`	meta is not installed globally	Run `npm i -g meta`
Child repos not cloned after `git pull`	New entries added to `.meta` without running update	Run `meta git update` to clone newly listed repos
Shell expression expands in meta context, not child	`$VAR` or backticks unescaped	Escape: `meta exec "echo \$(pwd)"` or `meta exec "echo \` pwd`"`

错误信息	原因	解决方法
`fatal: destination path already exists`	子仓库目录已存在，但未在 `.meta` 中注册	删除该目录，或执行 `meta project import` 将其注册
命令仅在元仓库根目录执行，未作用于子仓库	`.meta` 中的项目映射可能为空或路径错误	检查 `.meta` 内容；确保路径与实际目录结构匹配
`meta: command not found`	未全局安装meta	执行 `npm i -g meta`
执行 `git pull` 后子仓库未被克隆	`.meta` 中新增了条目但未执行更新命令	执行 `meta git update` 克隆新列出的仓库
Shell表达式在元仓库上下文而非子仓库上下文中展开	`$VAR` 或反引号未转义	进行转义： `meta exec "echo \$(pwd)"` 或 `meta exec "echo \` pwd`"`

Gotchas

注意事项

Child repo directories are in
.gitignore
but still show up as untracked if
.gitignore
was edited manually -
```
meta project create/import
```
appends to
```
.gitignore
```
automatically. If you manually edit
```
.meta
```
without using the
```
meta project
```
command, the corresponding path is never added to
```
.gitignore
```
, and the child repo's contents leak into the meta repo's git status. Always use
```
meta project create
```
or
```
meta project import
```
rather than editing
```
.meta
```
directly.
meta git clone
requires SSH key access to every child repo - The clone command attempts to clone all repos listed in
```
.meta
```
in parallel. If your SSH key lacks access to even one child repo, that clone fails and the error is easy to miss in the parallel output. Check that the cloning user has access to all repos before running
```
meta git clone
```
for a new developer.
Shell variable expansion happens in the meta context, not the child repo context -
```
meta exec "echo $PWD"
```
expands
```
$PWD
```
to the meta repo root before fanout, so every child repo prints the same (wrong) path. Escape the variable:
```
meta exec "echo \$PWD"
```
to expand it inside each child's shell.
meta git update
does not pull - it only clones missing repos - After a teammate adds a new child repo to
```
.meta
```
and you pull the meta repo, your existing child repos are not updated. You need to run
```
meta git update
```
to clone the newly listed repos, then separately run
```
meta git pull
```
to update all existing repos. Confusing these two commands is a common source of stale code.
Plugins must be installed globally, not just as devDependencies -
```
meta
```
resolves plugin commands from the global
```
node_modules
```
. A plugin listed only in the meta repo's
```
package.json
```
devDependencies will not be found when running
```
meta
```
commands unless it is also installed globally or the repo's
```
node_modules/.bin
```
is in PATH. Install frequently used plugins with
```
npm i -g meta-<plugin>
```
.

子仓库目录已在
.gitignore
中，但如果手动编辑
.gitignore
，仍会显示为未跟踪状态 -
```
meta project create/import
```
会自动向
```
.gitignore
```
中追加内容。如果你手动编辑
```
.meta
```
而不使用
```
meta project
```
命令，对应的路径不会被添加到
```
.gitignore
```
中，子仓库的内容会泄露到元仓库的Git状态中。请始终使用
```
meta project create
```
或
```
meta project import
```
，而非直接编辑
```
.meta
```
。
meta git clone
需要对所有子仓库拥有SSH密钥访问权限 - 克隆命令会尝试并行克隆
```
.meta
```
中列出的所有仓库。如果你的SSH密钥无法访问其中任何一个子仓库，该克隆会失败，且错误在并行输出中容易被忽略。在为新开发者执行
```
meta git clone
```
前，请确认克隆用户拥有所有仓库的访问权限。
Shell变量扩展会在元仓库上下文而非子仓库上下文中进行 -
```
meta exec "echo $PWD"
```
会在命令分发前将
```
$PWD
```
扩展为元仓库的根目录，导致所有子仓库输出相同的（错误）路径。请对变量进行转义：
```
meta exec "echo \$PWD"
```
，使其在每个子仓库的Shell中展开。
meta git update
不会拉取代码——它只会克隆缺失的仓库 - 当队友向
```
.meta
```
中添加了新的子仓库，你拉取元仓库后，现有子仓库不会被更新。你需要执行
```
meta git update
```
来克隆新列出的仓库，然后单独执行
```
meta git pull
```
来更新所有现有仓库。混淆这两个命令是代码过时的常见原因。
插件必须全局安装，不能仅作为devDependencies安装 -
```
meta
```
会从全局
```
node_modules
```
中解析插件命令。仅在元仓库的
```
package.json
```
devDependencies中列出的插件，在执行
```
meta
```
命令时会找不到，除非它也被全局安装，或者仓库的
```
node_modules/.bin
```
在PATH中。请使用
```
npm i -g meta-<plugin>
```
安装常用插件。
