'importing go files in same folder
I am having difficulty in importing a local go file into another go file.
My project structure is like something below
-samplego
--pkg
--src
---github.com
----xxxx
-----a.go
-----b.go
--bin
I am trying to import a.go inside b.go. I tried the following,
import "a"
import "github.com/xxxx/a"
None of these worked..I understand I have to meddle up with GOPATH but I couldn't get it right. Presently my GOPATH is pointing to samplego(/workspace/samplego).I get the below error
cannot find package "a" in any of:
/usr/local/go/src/pkg/a (from $GOROOT)
/workspace/samplego/src/a (from $GOPATH)
Also, how does GOPATH work when these source files are imported into another project/module? Would the local imports be an issue then? What is the best practice in this case - is it to have just one go file in module(with associated tests)?
Solution 1:[1]
No import is necessary as long as you declare both a.go and b.go to be in the same package. Then, you can use go run to recognize multiple files with:
$ go run a.go b.go
Solution 2:[2]
./main.go (in package main)
./a/a.go (in package a)
./a/b.go (in package a)
in this case:
main.go import "./a"
It can call the function in the a.go and b.go,that with first letter caps on.

I just wanted something really basic to move some files out of the main folder, like user2889485's reply, but his specific answer didnt work for me. I didnt care if they were in the same package or not.
My GOPATH workspace is c:\work\go and under that I have
/src/pg/main.go (package main)
/src/pg/dbtypes.go (pakage dbtypes)
in main.go I import "/pg/dbtypes"

If none of the above answers works,
Just try,
go run .
for production,
go build
This will take care of all the .go files in the folder.

As people mentioned previously, there is no need to use any imports.
A lot of people mention that using go run is possibe when you mention most files, however when having multiple .go-files in the same dir it can be cumbersome.
Therefore using go run *.go is what I usually do.

As I understand for packages in your project subfolders it's possible now to do, just need to add "." in front of module, like
. "github.com/ilyasf/deadlock-train/common"
where github.com/ilyasf/deadlock-train my main module name and common is just package from /common subfolder inside project.
