I'm trying to monkeypatch the []= method in the Hash class:
Hash.class_eval do
def []_with_feature=(a,b)
puts 'foo'
end
alias_method_chain :[]=, :feature
end
Something is wrong with the syntax, but I can't figure out what. The
alias_method_chain method does look for punctuation (= in this case)
and expects it to be at the end of the aliased method ([]
_with_feature=), but I get the following syntax error:
SyntaxError: compile error
(irb):5: syntax error, unexpected ')', expecting '='
(irb):7: syntax error, unexpected kEND, expecting ')'
(irb):9: syntax error, unexpected kEND, expecting ')'
Any ideas?
Thanks,
