Git递归地将遥控器添加到子模块 [英] Git add remotes to submodules recursively

问题描述

我在计算机上的/path/to/repo上有一个git repo，其中包含几个子模块/path/to/repo/submoduleA和/path/to/repo/foo/bar/submoduleB.

I have a git repo located on my machine at /path/to/repo, which contains several submodules, /path/to/repo/submoduleA and /path/to/repo/foo/bar/submoduleB.

由于我无法更改工作流程，因此git repo被复制(如在scp -r中一样)复制到远程服务器上，我在该服务器上处理代码.我想将所做的更改拉回到原始计算机上.不能从远程服务器进行克隆/推送.

Due to a workflow that I cannot change, the git repo gets copied (as in scp -r) to a remote server, where I work on the code. I want to pull the changes back to the original machine. Cloning/pushing from the remote server isn't an option.

转到每个子模块并执行

git remote add <name> <url>:/server/path/to/repo/<path to submodule>

有更快的方法吗?神奇的东西

Is there a faster way? Something magical like

git remote add --submodules <name> <url>:/server/path/to/repo

会递归到每个子模块，并将适当的相对路径添加到每个子模块的远程位置? git remote --help没有显示任何有用的内容，并且 Git专业版书子模块部分.

executed from the top-level repo that will recurse to each submodule and add the appropriate relative path onto the remote of each submodule? git remote --help doesn't show anything useful, and neither the Git Pro Book section on submodules.

我最好的猜测是

git submodule foreach 'git remote add <name> <url>:/server/path/to/repo/...'

可能会起作用.我只是不知道git submodule foreach

might work, if there there is a way to replace the ... with the loop-dependent relative path of each submodule in that foreach. I just don't know of such a mechanism built into git submodule foreach

推荐答案

git submodule foreach does include a list of variables which should help:

该命令可以访问变量:

The command has access to the variables:

• $name:.gitmodules中相关子模块节的名称，
• $sm_path:直接超级项目中记录的子模块的路径
• $displaypath:包含从当前工作目录到子模块根目录的相对路径，
• $sha1:直接超级项目中记录的提交，并且
• $toplevel:指向直接超级项目顶层的绝对路径.
• $name: the name of the relevant submodule section in .gitmodules,
• $sm_path: the path of the submodule as recorded in the immediate superproject,
• $displaypath: contains the relative path from the current working directory to the submodules root directory,
• $sha1: the commit as recorded in the immediate superproject, and
• $toplevel: the absolute path to the top-level of the immediate superproject.

所以在您的情况下:

git submodule foreach 'git remote add $name <url>:/server/path/to/repo/$sm_path'

$displaypath会将...替换为每个子模块的依赖于循环的相对路径.
但是，正如

$displaypath would replace the ... with the loop-dependent relative path of each submodule.
But, as noted by the OP waldol1 in the comments, $sm_path is a fixed value, as opposed to a relative path.

在子文件夹中执行的 docker/docker.github.io 的示例 tests:

D:\git\docker.github.io\tests>git submodule foreach "echo $displaypath"
Entering 'src/github.com/gdevillele/frontparser'
src/github.com/gdevillele/frontparser

vs.

D:\git\docker.github.io\tests>git submodule foreach "echo $sm_path"
Entering 'src/github.com/gdevillele/frontparser'
tests/src/github.com/gdevillele/frontparser
