[newbie] packaging and including.

<p>I am following <a href="https://thenewstack.io/make-a-restful-json-api-go/" rel="nofollow">this guide</a>. </p> <p>So at my current working directory I have five files. handles.go, logger.go, routes.go routes.go and main.go. </p> <p>My main.go looks like the following: </p> <pre><code>package main import ( &#34;log&#34; &#34;net/http&#34; ) func main() { router := NewRouter() log.Fatal(http.ListenAndServe(&#34;:8080&#34;, router)) } </code></pre> <p><code>NewRouter</code> is a function defined in <code>routes.go</code>. Several other functions are also being called among those <code>.go</code>. In the tutorial, I see no include/import statement for those <code>.go</code> files; My guess is there must be some parameters that&#39;s being passed in <code>go build</code> or <code>go run</code> that will incorporate all the files? if so what is it? </p> <hr/>**评论：**<br/><br/>sxan: <pre><p>If all files are in the same directory, and they&#39;re all in package main, no imports are needed.</p></pre>juniorsysadmin1: <pre><p>it doesn&#39;t work when I do <code>go run main.go</code> it complain about the routerfunction that is defined in <code>routes.go</code>.</p></pre>TheMerovius: <pre><p>Use <code>go build</code> or <code>go run *.go</code>. run and build have very different behaviors, run is for running a set of go-files, whereas build is for building a package.</p></pre>bishopknight1977: <pre><p>If you&#39;re using Gogland for IntelliJ you need to specify the run configuration to package . I had the same problem until I changed it. </p></pre>thornag: <pre><p>You need to include all the files when running or building</p> <p>go run ./... or go run *.go</p></pre>
