Subject: Did not manage to use data type //bool with YAML document
The validation of the //bool type does not seem to work when using a YAML input document. With the following simple schema: %YAML 1.1 --- type: //rec required: abool: //bool there seems to be no way of creating a valid document. I tried: %YAML 1.1 --- abool: true and replaced true with T, t, 1, ... without success. The result is always: Failed type: found value was not a bool (error: type at $data->{abool})

Ah - sorry for not mentioning this. I'm using the YAML:Any module which, on my system, seems to select YAML:XS/LibYaml as the actual parser backend.

I just also tried with the perl version of YAML (use YAML qw(...);) with the same result as reported earlier. I currently don't have YAML::Syck, but could also install it if that helps.

Thanks, I will look into this today or tomorrow. -- rjbs

Okay! So, the problem is that unlike JSON, YAML (and other libraries) does nothing to mark the loaded value as a boolean rather than anything else. In other words, "true" becomes a 1. In JSON, it would become an object. Although I have heard it promised that it would be possible to get a boolean object back from YAML, I am not aware of any means to do this. I suggest either using a "//any of [ //bool [any [ //int 0, //int 1 ] ] ]" instead, or writing a replacement //bool that allows 1/0 for perl. This is just one of those places where cross-language stuff gets awkward. Oh. Or you could use JSON. ;) -- rjbs
