Use package <a href="https://github.com/kardianos/osext" rel="noreferrer">osext</a>

It's providing function <code>ExecutableFolder()</code> that returns an absolute path to folder where the currently running program executable reside (useful for cron jobs). It's cross platform.

None of the answers here worked for me, at least on <code>go version go1.16.2 darwin/amd64</code>. This is the only thing close to the <code>__dirname</code> functionality in node
This was posted by goland engineer <a href="https://intellij-support.jetbrains.com/hc/en-us/community/posts/360009685279/comments/360002183640" rel="nofollow noreferrer">Daniil Maslov in the jetbrains forums</a>
pasted below for easier reading:
<hr />
The trick is actually very simple and is to get the current executing and add <code>..</code> to the project root.
Create a new directory and file like <code>testing_init.go</code> with the following content:
<pre class="lang-golang prettyprint-override"><code>package testing_init

import (
 &quot;os&quot;
 &quot;path&quot;
 &quot;runtime&quot;
)

func init() {
 _, filename, _, _ := runtime.Caller(0)
 dir := path.Join(path.Dir(filename), &quot;..&quot;)
 err := os.Chdir(dir)
 if err != nil {
 panic(err)
 }
}

</code></pre>
After that, just import the package into any of the test files:
<pre class="lang-golang prettyprint-override"><code>
package main_test

import (
 _ &quot;project/testing_init&quot;
)

</code></pre>
Now you can specify paths from the project root

If your file is not in the <code>main package</code> then the above answers won't work
I tried different approaches to find find the directory of the currently running file but failed.
The best possible answer is in the <code>question itself</code> this is how I find the current working directory of the <code>file which is not in the main package</code>.
<pre><code>_, filename, _, _ := runtime.Caller(1)
pwd := path.Dir(filename)
</code></pre>

Gustavo Niemeyer's answer is great.
But in Windows, runtime proc is mostly in another dir, like this:

<pre><code>"C:\Users\XXX\AppData\Local\Temp"
</code></pre>

If you use relative file path, like <code>"/config/api.yaml"</code>, this will use your project path where your code exists.

In nodejs I use <a href="http://nodejs.org/api/globals.html#globals_dirname">__dirname</a> . What is the equivalent of this in Golang?

I have googled and found out this article <a href="http://andrewbrookins.com/tech/golang-get-directory-of-the-current-file/">http://andrewbrookins.com/tech/golang-get-directory-of-the-current-file/</a> . Where he uses below code

<pre><code>_, filename, _, _ := runtime.Caller(1)
f, err := os.Open(path.Join(path.Dir(filename), "data.csv"))
</code></pre>

But is it the right way or idiomatic way to do in Golang?

How to get the directory of the currently running file?

Windows

在nodejs中，我使用。在Golang中与此相当的是什么？我已经在谷歌上找到了这篇文章。他在其中使用了以下代码_, filename, _, _ := runtime.Caller(1)f, err := os.Open(path.Join(path.Dir(filename), "data.csv"))但是在Golang中这是正确的方式还是惯用的方式呢？
