String -> symbol

Ruby
1

ok - i’m officially an idiot.

i want to dynamically alias the names of all methods in a module… i
need to string-manipulate the original method name to get the new one.
alias_method only takes symbol names and the only tricks i know to
convert strings to symbols (i.e., method(“this_func”) and
SomeClass.method_eval("this_func) don’t apply.

my_module.instance_modules.each{ |m|
m_new_name =
alias_method <what goes here?> <and what goes here?>

more generally, is there some easy way to convert strings to symbols
that i’ve missed?

thanks
m

“a_string”.to_sym # => :a_string

Is String#to_sym (or String#intern) what you looking for?

Is String#to_sym (or String#intern) what you looking for?

Which one is in fact preferred?

That isn’t true. alias_method takes strings just fine:

class A; alias_method ‘foo’, ‘to_s’;end; A.new.foo

=> “#<A:0xb7cfcf08>”

Either one, they are synonymous.
