importing go files in same folder

Question

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

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

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

Any number of files in a directory are a single package  symbols declared in one file are available to the others without any imports or qualifiers  All of the files do need the same package foo declaration at the top  or you ll get an error from go build     You do need GOPATH set to the directory where your pkg  src  and bin directories reside  This is just a matter of preference  but it s common to have a single workspace for all your apps  sometimes  HOME   not one per app   Normally a Github path would be github com username reponame  not just github com xxxx   So if you want to have main and another package  you may end up doing something under workspace src like  github com    username      reponame        main go      package main  importing  github com username reponame b        b          b go       package b   Note you always import with the full github com     path  relative imports aren t allowed in a workspace  If you get tired of typing paths  use goimports  If you were getting by with go run  it s time to switch to go build  run deals poorly with multiple-file mains and I didn t bother to test but heard  from Dave Cheney here  go run doesn t rebuild dirty dependencies   Sounds like you ve at least tried to set GOPATH to the right thing  so if you re still stuck  maybe include exactly how you set the environment variable  the command  etc   and what command you ran and what error happened  Here are instructions on how to set it  and make the setting persistent  under Linux UNIX and here is the Go team s advice on workspace setup  Maybe neither helps  but take a look and at least point to which part confuses you if you re confused
