Add this to have something to track this with.

The main blocker I see for this is that it's not possible to control location/timezone for dates without that information.

package main

import (
	"fmt"
	"log"

	v2 "gopkg.in/yaml.v2"
	v3 "gopkg.in/yaml.v3"
)

var data = `
d: 2021-07-15

`

func main() {
	mv2 := make(map[string]interface{})
	err := v2.Unmarshal([]byte(data), &mv2)
	if err != nil {
		log.Fatalf("error: %v", err)
	}
	fmt.Printf("--- mv2: %T %v \n", mv2["d"], mv2["d"])

	mv3 := make(map[string]interface{})
	err = v3.Unmarshal([]byte(data), &mv3)
	if err != nil {
		log.Fatalf("error: %v", err)
	}
	fmt.Printf("--- mv3: %T %v \n", mv3["d"], mv3["d"])
}

Prints:

--- mv2: string 2021-07-15 
--- mv3: time.Time 2021-07-15 00:00:00 +0000 UTC

Note that v2 isn't perfect, either, but that at least allows us to handle known dates (e.g. the front matter dates).

Everyone once in a while a user gets burned by "on/off/yes/no" keys. This happened again yesterday. While I understand why this is blocked, I must say I have little sympathy for unqualified dates. If we could start over, or break some eggs, I'd place every unqualified date in Etc/UTC.

Consider replacing github.com/go-yaml/yaml (last updated 2.5 years ago) with github.com/goccy/go-yaml which, at the moment, is actively maintained with 1.2k stars.

What we get:

  • Eliminates the Norway problem. Booleans are true|True|TRUE|false|False|FALSE. This would be a breaking change for anyone who has been using any of these to represent a boolean value: y|Y|yes|Yes|YES|n|N|no|No|NO|on|On|ON|off|Off|OFF.

  • Ability to disallow duplicate keys instead of letting the last one win (see #8427).

  • Helpful error messages:

    Error: error building site: process: readAndProcessContent: "/home/jmooring/code/hugo-testing/content/_index.md:43:1": failed to unmarshal YAML: [4:15] unexpected key name
   1 | title: home
   2 | date: 2024-11-09
   3 | params:
>  4 |   event_date: 2024-12-31T07:43:15-08:00
   5 |     foo: bar

  • The problem we ran into when looking at upgrading to github.com/go-yaml/yaml v3 does not seem to apply here. See v3: No way to control location of short dates go-yaml/yaml#770.

I must say I have little sympathy for unqualified dates.

Just to be clear, this is a very common "unqualified date" (for one, it's very easy to type, which I have sympathy for ...):

publishDate: 2021-07-15

Having the above mean UTC, would create very surprising beheaviour.

Out of the box it's significantly slower than what we had:
