Go: How does go run file.go work

Question

The commands go build and go install compile the files into binaries. Does go run compile or interpret the file? I couldn\'t find expl

Answer 1

It's more or less the equivalent of running go build X.go -o /tmp/random-tmp-folder/exe && /tmp/random-tmp-folder/exe

Answer 2

Unlike in java, where the bytcode is created and interpreted at the execution time, go creates an executable file that is dependent on the machine being used,like in c, c++.

Answer 3

Command go run performs project's building under the hood (so yes it builds project)
and with flag --work (go run --work main.go) you can see the location of temporary build files.

Also in official documentation (go1.11) you can find:

go run - compiles and runs the named main Go package.

go build - compiles the packages named by the import paths, along with their dependencies, but it does not install the results.

go install - compiles and installs the packages named by the import paths.

Answer 4

The go run command compiles and runs a main package comprised of the .go files specified on the command line. The command is compiled to a temporary folder.

The go build and go install examine the files in the directory to determine which .go files are included in the main package.
