Sort answer, because m["foo"] is not addressable, but you can have the 
desired behavior using a temp variable:


func f() {
m := make(map[string]struct{ i int })
x := m["foo"]
x.i = 42
m["foo"] = x
}

BR.

[go-nuts] Newbie question

[Daniel Jankins]

Hi,

Why can you update a value in a map struct?

 // UnaddressableFieldAssign occurs when trying to assign to a struct field

// in a map value.
//
// Example:
//  func f() {
//  m := make(map[string]struct{i int})
//  m["foo"].i = 42
//  }

I am reading a yaml file and want to change some values in the struct.
Thank s

[go-nuts] Re: Help Bootstrapping to ESXi

[Brian Candler]

"Bootstrapping go" means "building the go compiler toolchain from 
scratch".  You almost certainly don't want to do this.  This is something 
you'd normally only attempt if there is not a suitable go binary 
distribution available for your system.

Go needs to run under an operating system. ESXi emulates a PC as a "virtual 
machine", but you cannot boot a PC directly into Go: that is, Go does not 
run on "bare metal".  So with ESXi you first need to create a VM, install 
an operating system inside it, and then you install Go inside that.

For example, if you installed a Linux VM under ESXi, then inside that VM 
you can install the Linux distribution of Go, which you can download 
from  https://go.dev/dl/.  Ditto if you chose to install a FreeBSD or 
Windows VM - you simply download the FreeBSD or Windows distribution of Go.
