Say I have a Go script, called script1, that has a function, function1, that does not take any inputs.

Can I call that function from a bash script?

  • Must you name it function1, instead of building a standard main function? Commented Apr 11, 2022 at 20:18
  • I have a main function, function1 is separate from it. Commented Apr 11, 2022 at 20:21
  • The normal way you do this in the Go world is to create a cmd/function1 subdirectory and put a separate main inside function1 Commented Apr 11, 2022 at 20:24

While you can add a main() function which would call your function1(), allowing a go run a single go file, you also have an alternative:

  • mkouhei/gosh: interactive Golang shell, which provides an easy-to-use interactive execution environment and enable to omit the main function
  • nickwells/gosh: allows you to write lines of Go code and have them run for you in a framework that provides the main() func and any necessary boilerplate code for some common requirements. The resulting program can be preserved for subsequent editing.
