Boolean values for YAML v1.2

[benmordaunt]

The v1.2 spec states that "true", "false", "on", "off" etc. should be interpreted as their boolean value counterparts.
As this library claims to support YAML 1.2, how is that handled, or do I just have to strcmp regardless?

Thanks

Well, the problem is that C does not have a native object model that maps directly to a YAML core schema.

So, a boolean as defined by the core schema cannot right now automatically converted to a 'C' bool type.

There is some work being done to have user-defined schemas that would handle these cases (among lots of others) but nothing is ready yet.

For now you can extract the string and strcmp(), perhaps even using the scanf family of functions of the library.

What's stopping {"true", "on", etc.} -> 1 (char), {"false", "off", etc.} -> 0 (char) ?

👍 Looking into this issue as well; wondering if you had any more thoughts on this?

I started writing some small scalar helps for handling types.

FWIW work is underway to support the builtin YAML spec schemas. That will support what you need among other things.
