You would expect `klass::FOO` where `FOO` is a private constant of `klass` to call `const_missing`, but currently it doesn't. This makes a small change so that `const_missing` will be called in such cases. In addition to similarity to `method_missing`, the main reason for doing this is it offers a way to deprecate public constants. Currently, if you have a public constant and want to make it a private constant, you can't do it without breaking possible callers. With this patch, you can make it a private constant, then override `const_missing` in the class, and have `const_missing` print a deprecation warning and then return the value of the constant. ---Files-------------------------------- 0001-Make-public-access-of-a-private-constant-call-const_.patch (2.68 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
