Re: [go-nuts] Go 1.16 and modules

[Jon Reiter]

i think it's gentler to look at this in the context of c's "hello world"
program.  the first version was missing both #include and void.  then it
got #include. then it got void.  i recall void issues with code from k&r v1
on my compiler in the mid 80s (i do not predate include statements).  i
recall a brian kernighan talk where he comments on precisely this point as
well.  for me it's not so much "it's easy just do it" but rather "it's
fairly easy and worth it for the clarity."

yes i know those are code changes while this is the build process -- this
is about quantum of effort required.  having said that: something to help
with missing modules in dependencies would be helpful as that is
significantly harder.  i was able to adjust c even as a novice.  a
casual/beginner today is likely not able to fork-and-update a dependency.

I may have missed it, but could you clarify why you can't just create your
sample.go and 'go run' it with Go 1.16? No need to create a module for
this.


/tmp$ ls go.mod
ls: cannot access 'go.mod': No such file or directory

/tmp$ cat sample.go
package main

import "fmt"

func main() {
   fmt.Println("hello")
}

/tmp$ go version
go version go1.16 linux/amd64

/tmp$ go run sample.go
hello


Or is your 'sample.go' importing code from outside the standard library?

Re: [go-nuts] Go 1.16 and modules

['Axel Wagner' via golang-nuts]

I understand many criticisms of modules, but I honestly don't really get
this one.
You can just do `go mod init foo` in an empty directory, if all you want is
some throwaway Go code. It doesn't actually seem very complicated to me, I
must say.

Re: [go-nuts] Go 1.16 and modules

[Rich]

I really WANT to use go modules on all my projects, but there are times I 
just want to write a quick piece of code that I can 'go run'. Its usually 
just 20 lines, just used to test something out like a rest call to an 
internal server (can't do that on go playground) and for me go modules just 
makes it more complex. So what I do is what Reto stated above, set an 
environment variable for GO111MODULE=OFF.  Now at the command line I can 
write a quick code sample and just type 'go run sample.go' and it runs.  
For my projects where I want go modules I use a Make file:

GO111MODULE=on GOOS=linux GOARCH=amd64 go build $(compilerFlag) -o 
mygoproject mygoproject.go othergofiles.go...

Yes: https://golang.org/ref/mod#mod-commands

Note that you can still run the hello world programs via `go run` without
having a module.
