strictyaml VS cson

NestedText already is the way I use YAML; everything is intepreted as a string. I have some trust in my YAML parser to not mangle most strings. I could use NestedText, but users would be unfamiliar with it, and IIRC the only parsers are in Python. But then I could use StrictYaml too https://github.com/crdoconnor/strictyaml

you can stick to a subset of YAML syntax (e.g. strictYAML)

YAML stands for "YAML Ain’t Markup Language" - this is known as a recursive acronym. YAML is often used for writing configuration files. It’s human readable, easy to understand and can be used with other programming languages. Although YAML is commonly used in many disciplines, it has received criticism on the amoutn of whitespace .yml files have, difficulty in editing, and complexity of the standard. Despite the criticism, properly using YAML ensures that you can reproduce the results of a project and makes sure that the virtual environment packages play nicely with system packages. (If you're looking for another way to share environments there are other alternatives to YAML which include StrictYAML (a type-safe YAML parser) and NestedText)

The example you linked provides this as an example of a YAML document that he wants his format to support.

That safe subset exists and is implemented in a number of languages. It is called strict-yaml: https://hitchdev.com/strictyaml/

StrictYAML\ (33 comments)

To me those are in the category of "nice to have", and the problem is that every developer has different preferences for these [1] [2]. But the main features of StrictYaml, like supporting comments and less syntactic noise, I think are pretty uncontroversial, and perhaps it's worth it to get people to switch over for those alone. It doesn't need to be perfect, it just needs to be a significant enough improvement over JSON, and I'd say those two features are more than enough

I prefer JSON over YAML because I spend more time confused and burned by the problems caused by it.

I understand that people don't like directly use JSON because it's not very friendly: no comments, no multi-line string, etc.

A great alternative IMHO is cson[0]. It's like JSON to JavaScript but for CoffeeScript (though nobody talks about it nowadays). It has indentation-based syntax, comments, and multiline string which usually don't need to escape. The advantage is it's close enough to JSON which is the canonical format that everybody can agree on nowadays. For YAML and TOML there are too many visual part-aways from JSON.

Or just create a JSON variant that enables comments and the backtick multiline string from JavaScript.
