Feature #20703: Alias StringIO#string to StringIO#to_s/to_str

• Status: Rejected
• Assignee: -
• Target version: -

[sebyx07 (Sebastian Buza)]

Description

Allow to use StringIO.new('my string').to_s to be the same as StringIO.new('my string').string

IMO nobody really uses the current StringIO#to_s, so I don't think it will break other apps.

• Also added .to_str

That way you can also do interpolation easily

my_sio = StringIO.new('my string')

# current
puts "value: #{my_sio}" # value: #<StringIO:0x0000764bba88eec0>

# after
puts "value: #{my_sio}" # value: my string

Might also consider adding #to_str, as I think it makes sense to consider StringIO to be a kind of string.

@Dan0042 (Daniel DeLorme) done, ty!

At this developers' meeting, no one was favor of this.

IMO, StringIO is not a String-like object.

[matz (Yukihiro Matsumoto)]

Since StringIO is a IO-like object, not String-like object, so it should not provide to_str. And string body of a StringIO tends to be long, so simple alias of string to to_s does not always work well.
So please use string method if you want string body from a StringIO.
