Yes, a bit. But that’s not the problem.
The problem is that the current fashion of devops is done through piles and piles of badly defined YAML. If it used any other configuration language, it would be just as bad.
Comment on A lot of YAML

Is Yaml bad ?
Yes, a bit. But that’s not the problem.
The problem is that the current fashion of devops is done through piles and piles of badly defined YAML. If it used any other configuration language, it would be just as bad.
It isn’t “bad”, as it does have a purpose. It’s just fucking annoying to work with.
How’s it annoying? It’s easier to edit by hand than json as it allows for comments and there’s no trailing comma errors. I prefer it any day over json.
There’s a lot of foot guns in YAML. The specification is way more complicated with hidden obscurities. JSON specification is just 5 diagrams. YAML speciation on the other hand is an 86 page pdf, so there’s more room for nasty surprises (which is not a thing you want in configuration files).
I’ve also seen many people struggle more than they need to with the yaml indentation.
I think the only upside to yaml is that it allows for comments, but other than that JSON all the way.

The fact that it allows comments is really, really handy. I used to be a JSON advocate until I realized this one useful piece of info.
Yeah, such a simple, but still killer feature. Really sad that JSON doesn’t support them.
It’s just another syntax to learn. For someone who already has their head crammed full of a bunch of other syntaxes over the years, I didn’t want to learn a new one. YAML has kind of forced it’s way in anyways though.
There are plugins that go back and forth between JSON and YAML so as you might expect it’s similar. Unlike JSON, spacing has semantic meaning, which can be a little annoying, especially when cutting and pasting. It’s nice in that configs aren’t cluttered up with open and close braces. It could be annoying AF if you’re a tabs instead of spaces person but idk because I’m a spaces person.
I like YAML for config over .config files but it’s not a big deal either way. It just encourages better organization of settings because the hierarchical structure demands it while .config let’s you just drop a setting anywhere in the file. But it’s valid to have the opposite preference for the exact same reasons.
I’ll answer your question with a question. Why does YAML support sexagesimal? (that’s base 60)
ports: - 22:22
Becomes
{ "ports": [1342] }
I learned the hard way that no is false in yaml. Took us a while to realize why our app failed to start in Norway. Too many ways to do something.
Even a ‘no’ is a ‘false’ ?
Yup. Have to ensure that you use “no” if you don’t want yaml to equate it to false.
not at all. it’s used for configuration and stuff. having a lot of it can be a real bummer depending on the context. like a puppet config or perhaps a super weird docker compose setup. I’ve never heard anyone complain about the markup though. it’s like blaming json for a crap api or something or idk blaming the coffee cup for burnt coffee 🤷
It’s just another structured data format. It’s used for a lot more than config. It’s also how you define commands and etc for Ansible. Like how a Maven project is defined in XML or a NodeJS package has its JSON.
Sure they’re still “just” data formats on their own, but what they’re used for is genuinely just as important as what it is. I really doubt XML would’ve held on like it has without HTML being the web.
For some little config it’s fine, but it’s horrible when used when you have thousands upon thousands of lines of it. Lots of DevOps tools tend to use it like a fully-blown turing-complete programming language, and each has a different DSL of doing variables, loops etc. And that becomes an abomination.

Not always, but the second you use anchor/references you have sold your soul in a Faustian bargain of convenience.
On the alignment chart of data/markup formats:

I honestly think that JSON and YAML should be swapped due to YAML’s strict indentation rules whereas you can just pack an entire JSON object on one line.

Also JSON has no comments. Which is great for me because I hate documenting my work, but it’s still annoying.

Just create an attribute for your comments!

I think yaml’s need for indentation alone makes it chaotic evil. I’ve seen so many people struggle with the indentation than they really need to it’s not fun. Especially problematic with large configuration files.
JSON is easy to unpack with tools like jq or whatever.
EmergMemeHologram@startrek.website 11 months ago
There are 6 different combinations of “interpret multiline whitespace” character patterns. There are three types of single-line strings, and if you use “Yes” or “No” the data gets type cast.
Yaml is chaotic.

Oh this is a good point - the syntax error on line one has ruined several productive days.
Of course the tool would happily prettify it for me, but it has to be valid json. Which I think would make it more enjoyable if it said in that message “Good luck, we’re counting on you.”
