Overview
go is a command line tool with multiple uses: package manager, build tool and test driver. go manage packages in workspaces, query metadata about packages, print documentation, build, format, download, test, etc.
Commands
Help
go help <command>
go help build
build
The build command compiles one or more packages and builds the executable if the package main is among the compiled packages.
cd ${PROJECT_DIR}
go build ./src/main/main.go
The command will create an executable named after the first source file, in this case main, and will place it by default in the ${PROJECT_DIR} directory.
To build in GOPATH mode, see:
install
doc
The doc command prints documentation for a package.
fmt
The fmt ("format") command formats source code files.
get
The get command downloads packages and installs them.
list
The list command lists all installed packages.
run
The run command compiles .go files and runs the executable.
cd $PROJECT_DIR
go run ./src/main/main.go
test
The test command runs tests. For more details, see:
env
The env command prints the effective values of the environment variables relevant to the tool chain.
go env GOOS GOARCH GOPATH
get
The get command retrieve and update packages.
