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)
Despite my love of yaml. I actually think he has a small point with unquoted strings. I teach students and see their struggles. Bash also does unquoted strings and basically all students go years and years without realizing
To know the difference between special and normal-but-no-quotes you have to know literally every special symbol. And, for example, its rare to realize the

in --help, isn’t special at a language level, its only special at a convention level.Same thing can happen in yaml files, but actually a little worse I’d say. In bash all the “special” things are at least symbols. But in yaml there are more special cases. Imagine editing this kind of a list:
Three of those are not strings. Syntax highlighting can help (which is why I don’t think its a real issue). But still “why are three not strings? Well … just because”. AKA there isn’t a syntax pattern, there’s just a hardcoded list of names that need to be memorized. What is actually challeging is, unless students start with a proper yaml tutorial, or see examples of quotes in the config, its not obvious that quotes will solve the problem (students think
"true"
behaves like"\"true\""
). So even when they seetrue
is highlighted funny, they don’t really know what to do about it. I’ve seem some try stuff like \true.Still doesn’t mean yaml is bad, every language has edge cases.
While the subjective assessment that quote handling in yaml is worse than bash is understandable, it is really just two of many many cases where quotes complicate things. And for a pretty good reason. They are used to isolate strings in many languages, even prose. They, therefore, always get special handling in lexical analysis. Understanding which languages use single quotes, double quotes, backticks, heredocs, etc and when to use them is really just part of the game or the struggle I guess.
