Hi Andrew, thanks for the code.
Ok, some code:
package main
import (
"fmt"
"<path to your toml pkg>"
)
//type A struct {
// Features map[string]string
//}
type A struct {
Features map[string]B
}
type B struct {
C string
}
func main() {
blob := `
[Bird]
[Bird.Features.color]
C = "white"
[Bird.Features.name]
C = "Polly"
[Dog]
[Dog.Features.color]
C = "black"
[Dog.Features.name]
C = "Fido"`
var a map[string]A
_, err := toml.Decode(blob, &a)
fmt.Printf("Toml decode produced error: %v\n", err)
fmt.Printf("Dog name = %v\n", a["Dog"].Features["name"].C)
}
So this works for me (with toml pkg location updated). But what if I want
to replace type B with a string value in the commented out version of type
A? How would the blob need to be formatted to eliminate B and its field C?

Could you give an example with with Go types? And perhaps also include the
TOML you think should go with it.

https://github.com/BurntSushi/toml and seems to work well
(thanks to the author).
But how to handle a map as field of primitives? e.g. with
type A struct {
Features map[string]string}
how would you format the toml file to ensure this could properly read in
a map such as {"key1": "val1", "key2": "val2"}? If instead we had
type A struct {
Features map[string]B}
type B struct {
C string
}
the toml doc:
[Bird]
[Bird.Features.color]
C = "white"
[Bird.Features.name]
C = "Polly"
[Dog]
[Dog.Features.color]
C = "black"
[Dog.Features.name]
C = "Fido"
seems like it works, but what about "anonymous" fields for maps? (or the
best workaround)
