#13 Stack dump at end of file

[David Nuttall]

If I end a YAML file with the last non-comment component being "- - -" (no spaces), then kwalify 0.7.1 (Ruby) dumps stack with no reasonable error message. This also happens if I follow that line with "..." For example: running on Ubuntu 10.04, with command line "kwalify -lf schema-defs.yaml junk.yaml" I get:
junk.yaml#0: valid.
/usr/lib/ruby/1.8/kwalify/main.rb:326:in `_show_errors': undefined local variable or method `kwalify' for #<Kwalify::Main:0xb76ecf14> (NameError)

Kwalify schema for object definition.

[David Nuttall]

The junky file to be validated that generates the stack dump.

Thank you for reporting a bug.
Could you attach (or write) a yaml file which raises error?

[Kuwata Makoto]

Thank you for reporting bugs.
Could you append files which raises error?
I tried the followings but no errors.

schema.yaml
-------------------------------
type: map
required: true
mapping:
"name":
type: str
required: true
"age":
type: int
required: false
-------------------------------

data.yaml
-------------------------------
name: "---"
age: 20
-------------------------------

result:
-------------------------------
$ kwalify -f schema.yaml data.yaml
data.yaml#0: valid.
-------------------------------

Sorry David, you already attached files.
I'll check it. Thank you.
