• GOROOT is the location where Go package is installed on your system. In Debian it is /usr/lib/go-1.10
• GOPATH is the location of your work directory. For example my project directory is ~/Projects/Proj1.
  • GO works with packages, GOPATH tells where to look for packages
  • All packages installed with go get goes to GOPATH.
  • Multiple projects (workspaces)has to be kept under different GOPATH
    • Looks strange but as a benefit: This let us to have all external packages in required version
  • all binaries will be stored in $GOPATH/bin

Single GOPATH:

You can have multiple projects in a single GOPATH. Each project will have a main.go in a different package. 
Often this is the right way to go. All the projects will share the same dependencies, when you 
upgrade a library each project will be updated. This works well when all the projects are updated and 
deployed together (like micro services).

GOPATH directory structure:

• src
• bin
• pkg

Example setup of GOPATH:

Edit ~/.bashrc to add the following line:

~/.bashrc

export GOPATH=$HOME/go

re-login to apply changes.

setpath Download: https://s3.ap-south-1.amazonaws.com/gosetpath/setpath_linux_64

cd ~/project/src
setpath go get github.com/golang/example/hello

setpath will automatically set GOPATH to correct path, even if executed deeply inside ~/project subdirs.

To download dep command:

setpath go get -u github.com/golang/dep/cmd/dep

dep reads two files called Gopkg.toml and the Gopkg.lock

Commands:

  init     Set up a new Go project, or migrate an existing one
  status   Report the status of the project's dependencies
  ensure   Ensure a dependency is safely vendored in the project
  version  Show the dep version information
  check    Check if imports, Gopkg.toml, and Gopkg.lock are in sync

cd ~/project/src/github.com/muka/go-bluetooth
setpath ${GOPATH}/bin/dep ensure

and new packages will be downloaded to ~/project/src/github.com/muka/go-bluetooth/vendor

GoClipse plugin for Eclipse. Installation: GoClipse installation

go get github.com/rogpeppe/godef
go get golang.org/x/tools/cmd/guru

Configure GO plugin:

• Preferences–>Go–>Tools and setup executables:
  • /usr/bin/gocode
  • /home/user/go/bin/guru
  • /home/user/go/bin/godef
  • /usr/bin/gofmt
• Preferences–>Go
  • Go installation: Directory /usr

panic: Can't find the package clause

Probably gocode version mismatch:

• try to update from github
• killall gocode
