What you means is this?
def superclasses : Array(Crystal::Meta::AbstractType)
a = [] of Crystal::Meta::AbstractType
{% begin %}
{% superklass = @type.superclass %}
until {{ superklass }} == Object
a << Crystal::Meta::Type.new({{superklass.name(generic_args: false)}})
{% superklass = superklass.superclass %}
end
{% end %}
a << Crystal::Meta::Type.new(Object)
end
although this code not work because dead loop.
BUG: {{ @type.name.stringify }} (Crystal::MacroExpression) at /home/zw963/Crystal/share/crystal/src/class.cr:149:11 should have been expanded (Exception)
I thought i don’t really understand why wrap those class into a Crystal::Meta::Type or Crystal::Meta::AbstractType is necessary, this may take some time to learn, but anyway, i add a Object#all_methods, it works as my expected.
def all_methods : Hash(String, Array(Crystal::Meta::AbstractMethod))
a = {self.class.to_s => methods}
superklass = self.superclass
until superklass == Object
a[superklass.to_s] = superklass.methods
superklass = superklass.superclass
end
a["Object"] = Object.methods
a
end
