I'm learning Go (using 1.9.2 on Centos 7). Consider the following
trivial program, which works fine:
package main
import "fmt"
type symbol struct {
name string
fn func(int)
options int
}
func main() {
symbols := [] symbol {
{"jon",x, 4},
}
symbols[0].fn(13)
fmt.Println("symbols: ", symbols)
}
func x(arg int) {
fmt.Println("x: arg = ", arg)
}
This does what I expect, which is to show how to
initialize a structure to contain various values.
I then tried to modify this program so that the structure
initialization is done outside any function, like so:
package main
import "fmt"
type symbol struct {
name string
fn func(int)
options int
}
var symbols = [] symbol {
{"jon",x, 4,}
}
func main() {
symbols[0].fn(13)
fmt.Println("symbols: ", symbols)
}
func x(arg int) {
fmt.Println("x: arg = ", arg)
}
However, this doesn't compile, saying
./bad.go:12:18: syntax error: unexpected newline, expecting comma or }
I don't understand how to fix this. I have to admit that I don't
know why one style would be preferred over the other, but I'd like to
understand how to correct the second case.
Cordially,
Jon Forrest
