GOPATH和Go Web Server：“运行myserver.go”

Question

I'm at the point where want to organize my Go web server into packages. Currently I have everything in a few files and I simply type:

How do I organize my files so I don't need to keep adding files to the command line. I've investigated the GOPATH variable but it doesn't seem to work.

export GOPATH=$HOME/myserver

I moved my files to the src/ subdirectory.

myserver/src/server.go
myserver/src/foo.go
myserver/src/bar.go

Shouldn't 'go run' search $HOME/myserver/src for all go files?

I've tried these examples but they don't work.

go run server.go; # Doesn't work
go run src/server.go; # Doesn't work

By the way, all files are in 'package main'

Answer 1

This info is covered really well on golang.org

Read this about how to write Go code

And this about organizing go code

Tip: you can run go run * to run all files in a folder

Your above example should look something like this

$GOPATH=$HOME

The GOPATH should have:

$GOPATH
    src/
    pkg/
    bin/

$GOPATH/src is where you would store your source code for each go project

$GOPATH/src/myserver would contain your myserver program

cd to $GOPATH/src/myserver and run go install and you would now have your myserver binary located at $GOPATH/bin/myserver

Add the location of your bin to your path export PATH=$PATH:$GOPATH/bin and you can run myserver to start your go program

Answer 2

go run will look for a file (or wildcard) in your current working directory.

If you would like to run your programs from anywhere, either use go build same as you would go run and move the binaries where appropriate or, better yet, set your $GOBIN environment variable and add it your $PATH -- then run go install * in your project directory.

It's also probably a good idea to make specific directories for projects instead just dumping it all in $GOPATH/src
