Is it possible to show map[string][]string as multiline and non-multiline at same time?

[aj3423]

I have two variables which have same type map[string][]string, representing an Address list and a Name list.

The Address is very long so I want to display it in different lines, and the Name is short and it's ok to display in one line.

The code:

package main

import (
	"bytes"
	"fmt"

	"github.com/pelletier/go-toml/v2"
)

type Config struct {
	Address map[string][]string `toml:",multiline"` // grouped by country
	Name    map[string][]string // grouped by age
}

func main() {
	cfg := &Config{}
	cfg.Address = map[string][]string{
		"some country": {
			"some very __________long________ address",
			"some very __________long________ address",
			"some very __________long________ address",
		},
		"some other country": {
			"some very __________long________ address",
			"some very __________long________ address",
		},
	}

	cfg.Name = map[string][]string{
		"20-30": {
			"name a", "name b", "name c" .. lots of names,
		},
	}

	buf := bytes.Buffer{}
	enc := toml.NewEncoder(&buf)
	enc.SetIndentTables(true)
	enc.Encode(cfg)

	fmt.Println(buf.String())

}

I found there is enc.SetArraysMultiline(true) which works for the long Address, but it also turns Name list to multiline.

Is it possible to show these arrays in different styles? Or maybe some feature like LineMaxWidth that it auto goes to new line if the width exceeds that number?

Thanks.

Sorry for the late reply! I think your intuition is right: toml:",multiline" should probably always push down the multiline tag to the value instead of keeping it on the map, for which it makes no sense.
