Yet another “brilliant” scheme from a cryptobro. Naturally this caused a gold-rush for scammers who outsourced random people via the gig economy to open PRs for this yml file (example)
I’ve used both YAML and a TOML-adjacent INI format for Ansible. While I wouldn’t use YAML for massive data serialization (because significant whitespaces are fucking stupid), it’s much better suited for manual data entry compared to most options, including TOML, when nested data structures are required.
And if YAML’s structure is too complicated, that’s honestly a skill issue.
Not that YAML’s structure is too complicated, but its syntax is too flexible. All the shit about being whitespace sensitive yet with whitespace errors leading to a syntactically valid YAML document. TOML’s syntax is rigid which makes it unsuitable for expressing complex nested data structures, which is good because that’s not what you should use TOML for. Ultimately the dependence on a highly flexible baseline language like YAML to create complex DSLs is a failure on the developers’ part, and the entire configuration system should be reworked.
Do you use a linter like the ansible vscode extension?
I used to hate writing ansible, and yaml, until I installed the ansible lint vscode extension, and everything became much, much easier.
Later on, when I was working on a docker-compose, I noticed that the vscode yaml extension (which the ansible extension pulled in as a dependency) caught errors. It’s quite intelligent, able to spot errors exactly like what you mentioned, where the yaml syntax is correct, but the docker-compose, or the ansible syntax is wrong.
Of course. If you’re working in a DSL that’s popular enough for someone to have written a good schema/parser for then tooling can help.
Significant white space is awesome! Not supporting tabs tho shows you don’t know what you are doing, YAML.
They very well know what they are doing. Take your filthy tabs and get out of here. Spaces only.
Tabs for indentation, spaces for alignment. It’s perfect. Lets people visually indent as much as they want in their settings, but manually aligned things stay manually aligned. Forcing indents to always be… whatever number of spaces you personally like is dumb.
Plus then you can outdent with a single Backspace in every text editor ever.
😧
Accessibility be damned
set expandtabThat just converts tabs to space but doesn’t address the underlying accessibility needs where some folks demand different indentation due to vision issues or nonstandard IO devices like braille readers. Tabs allow the user to configure the width for their needs. Being static spaces ignores the needs of many folks.
Very good point re. Braille readers. I was being flippant and did not think of that. My apologies. Tabs for indentation may be useful there. as would a blind-friendly pre- and post- processor for programming language specific files (a braille liner, could call it black-er for python :)
I don’t know how braille readers actuality work, but I guess they process a bytestream. How do they handle utf-16 and other non standard character sets? This is a known problem for a lot of systems- it would be interesting to know how they address it.
Have you met any such person?
I have interacted with triple digits number of developers and I have met exactly zero folk with such a need. If there is an actual need by a team member, sure, we will be accommodating.
Until then, however, the much more common thing is for people to have their own preferences for tab width and ignore the current code style, ending up in an identation abomination that sucks for everyone. Therefore, no thanks, forced width for everyone, using spaces.
No point ruining the happy path scenario for a theoretical person with such a disability. If there will be an actual need, sure, let’s convert to tabs only then.
Can you give an example where a person’s personal tab width breaks things? One tab per logical indent, and then spaces for alignment. How does this break anything? I know for a fact it doesn’t or else people like me wouldn’t advocate for it. What breaks indenting is mixing tabs and spaces for indents, and obviously that’s foolish. You can’t blame that mistake for causing an “abomination” when it’s something that would violate any code style specification, whether using spaces or tabs. You yourself could set your IDE to emit only 2 spaces when you hit Tab, and that would also violate your code style spec if you mix those indents into a file with 4-space indents, and that has nothing to do with tabs at all.
Doing stupid things in the code that violates the code style are stupid things that violate the code style. No matter what whitespace you use. But having a personal setting to see 8 spaces per tab isn’t one of them if you only use tabs for logical indenting and not for alignment.
All tabs or all spaces for indents result in the exact same thing: good looking code. But tabs then have further advantages. Easier outdenting, better accessibility, etc. The only benefit to forcing spaces is that some random program you use for code comparison or whatever might default to something other than 4 columns for a Tab and your code looks a little wide until you change your settings. That’s nothing compared to the advantages of tabs. Turns out that “benefit” of spaces is actually a drawback because no one is allowed to view the indents as anything but whatever column width you personally think it should be.
I am literally that person, but kay
