Just say Norway to YAML.

▲ merelysounds 8 hours ago | parent [-]

This is a reference to YAML parsing the two letter ISO country code for Norway:

    country: no

As equivalent to a boolean falsy value:

    country: false

It is a relatively common source of problems. One solution is to escape the value:

    country: “no”

We stopped having this problem over ten years ago when spec 1.1 was implemented. Why are people still harking on about it?

A new spec version doesn’t mean we stop having the problem.

E.g. kubernetes wrote about solving this only five months ago[1] and by moving from yaml to kyaml, a yaml subset.

The 1.1 spec was released about _twenty_ years ago, I explicitly used the word _implemented_ for a reason. As in: Our Yaml lib vendor had begun officially supporting that version more than ten years ago.

		Note that you reference 1.1, I think that version still had the norway behavior.

Because there's a metric ton of software out there that was built once upon a time and then that bit was never updated. I've seen this issue out in the wild across more industries than I can count.

I’m not here clanking down on Java for lacking Lambda features, the problem is that I did not update my Java environment past the 2014 version, not a problem with Java.

I think this mixes up two separate things. If you're working with Java, it's conceivable that you could probably update with some effort. If you're an aerospace engineer using software that was certified decades ago for an exorbitant amount of money, it's never going to happen. Swap for nearly any industry of your liking, since most of the world runs on legacy software by definition. A very large number of people running into issues like these are not in a position where they could solve the problem even if they wanted to.

		That’s about 99% of the argument I am making. The problem is legacy software and bad certification workflows, not the software being used. If I’m working with Java it’s indeed conceivable that I could update with some effort. If I’m working with Node it’s conceivable that I could update with some effort. If I working with YAML is it not conceivable that I could update with some effort? PHP is stupid because version 3 did not support object oriented programming. CSS is bad because version 2 did not support grid layouts or flexbox. Why should I critique on these based on something that they have fixed a long time ago instead of working on updating to the version which contain the fix I am complaining about? There is a gradient limit where the onus shifts squarely to one side once the spec has changed and a number of libraries have begun supporting the new spec.

Now add brackets and end-tags, I'll reconsider. ;)

		Brackets works fine: `Roles: [editor, product_manager]` End tags, that I’m not sure what that is. But three dashes is part of the spec to delineate sections: `something: setting: true --- another: thing: false`

Because once a technology develops a reputation for having a problem it's practically impossible to rehabilitate it.
