I feel that Yaml sucks. I understand the need for such markup language but I think it sucks. Somehow it’s clunky to use. Can you explain why?

Can you stop hating on haters? Thanks 😄
stop hating on rust devs
Because people over use it. YAML is pretty good for short config files that need to be human readable but it falls apart with complex multi line strings and escaping.
I think there are much better clearly delimited for machine reading purposes formats out there that you should prefer if you’re writing a really heavy config file and, tbh, I think for everything else
.iniis probably “good enough”.At least use TOML if you like ini, there is no ini spec but TOML can look quite similar.
YAML is fine if you use a subset (don’t use the advanced features - not like you know those anyway) and use explicit strings (always add
"to strings), otherwise things may be cast when you did not intend values to be cast.Example:
country: NO(Norway) will be cast tocountry: False, because it’ll castno(regardless from casing) tofalse, andyestotrue.country: "NO"should not be cast.People are working on making S-Expressions a standard: https://datatracker.ietf.org/doc/draft-rivest-sexp/
Note: This is just a draft, but improvements have been happening since 2023.
I probably won’t like the parentheses, but I think I’ll take it over yaml/json/whateverelse.
That appears to not support comments. How they made that mistake after JSON is a mystery.
Any language in which whitespace has syntactic value is intrinsically flawed.
Can’t speak to your specific issues, but that’s why yaml will always suck.
YAML sucks because, among other things, indenting it is not obvious.
In contrast, the only mistake of Python when it comes to whitespaces was allowing hard tabs, which makes it too easy to mix them if your editor is not configured.
Improper indentation stands out more than missing or unbalanced braces and it’s really not an issue to delimit code blocks.
As a serialization format, agree 100%, but would Python really be better if it switched to braces?
Yes, I think so. The downside with Python comes when refactoring the code. There’s always this double checking if the code is correctly indented after the refactor. Sometimes small mistakes creep in.
It’s really hard to tell when Python code is incorrectly indented. It’s often still valid Python code, but you can’t tell if it’s wrong unless you know the intention of the code.
In order languages it’s always obvious when code is incorrectly indented. There’s no ambiguity.
Haskell supports both semantic whitespace and explicit delimiters, and somehow almost everybody that uses the language disagrees with you.
But anyway, for all the problems of YAML, this one isn’t even relevant enough to point out. Even if you agree it’s a problem. (And I agree that the YAML semantic whitespace is horrible.) If YAML was a much better language, it would be worth arguing whether semantic whitespace breaks it or not.
Yeah but Haskell is mostly used by mathematicians…
Not any language. I code professionally in F# which has semantic whitespace and it has literally never been an issue for me or my team. In contrast to Python, it’s a compiled language and the compiler is quite strict, so that probably helps.
