如何开发和测试本地go模块 [英] How to develop and test a local go module

问题描述

我有这个脚本:

#!/usr/bin/env bash

set -eo pipefail

cd "$(dirname "$BASH_SOURCE")";
pth_to_make="$GOPATH/src/ores/json-logging"
mkdir -p "$pth_to_make";
rm -rf "$pth_to_make";
ln -sf "$PWD" "$pth_to_make";

但是在go.mod中没有将该模块声明为go模块...我正在将另一个依赖项符号链接到仓库中以对其进行测试.

however this module is not declared as a go module in go.mod...I am symlinking a different dependency into the repo to test it.

生产中的真正依存关系是:

The real dependency in production is at:

"$GOPATH/src/github.com/oresoftware/json-logging"

测试路径为:

"$GOPATH/src/ores/json-logging"

现在，我只想删除本地开发中的真实依赖关系路径，问题是它只删除了仓库中的.git文件夹，然后我不得不再次下载它.

Now, I would just delete the real dependency path in local development, the problem is that it then just deletes the .git folder in the repo and then I end up having to download that again.

我是否可以通过某种方式对真正的repo/dep文件夹进行符号链接，但又不会丢失git的东西?也许我可以做:

Is there some way for me to symlink over the real repo/dep folder, but not lose the git stuff? Maybe I could do:

 mv   "$GOPATH/src/github.com/oresoftware/json-logging"  "/tmp/gotemp/json-logging"
 # call the script above
 # then when I am done:
 rm -rf "$GOPATH/src/github.com/oresoftware/json-logging"
 mv "/tmp/gotemp/json-logging" "$GOPATH/src/github.com/oresoftware/json-logging"  # put it back

那是最好的前进方式吗?

would that be the best way forward?

推荐答案

因此，在我的评论中，听起来好像您所追求的是 replace 指令，您可以阅读有关此处.但我在下面概述了一个简单的例子；

So to expand on my comment it sounds like what you are after is the replace directive which you can read more about here. But i've outlined a brief example below;

如果我们想象一下目录结构:

If we imagine the directory structure:

├── replace-directive
│   ├── go.mod
│   └── replace.go
├── sandbox
│   ├── go.mod
│   └── main.go

replace-directive 是一个go模块，其中的 go.mod 文件包含:

The replace-directive is a go module with the go.mod file containing:

module example.com/replacedirective

go 1.14

沙盒是我们要使用此本地依赖版本的地方，而不是从 example.com 抓取的版本.因此，在我们的沙盒 go.mod 文件中，我们具有如下所示的replace指令；

Sandbox is where we want to use this local dependency version rather than grabbing the version from example.com. So in our sandbox go.mod file we have the replace directive as follows;

module example/sandbox

require (
  example.com/replacedirective v0.0.0  // This would be your reference to your production dependency
)

replace example.com/replacedirective => ../replace-directive // This is your local dependency

go 1.14

因此，现在当您在代码中引用模块时，它将使用本地依赖项代替.无需符号链接.

So now when you reference the module in your code it will use your local dependency instead. No symlinks required.
