ruby.git/test/-ext-/string/test_ellipsize.rb, branch v4.0.3 The Ruby Programming Language Make String methods return String instances when called on a subclass instance 2020-11-21T00:30:23+00:00 Jeremy Evans code@jeremyevans.net 2020-10-24T18:52:30+00:00 58325daae3beefda13ed100782cd19a89cc68771 This modifies the following String methods to return String instances instead of subclass instances: * String#* * String#capitalize * String#center * String#chomp * String#chop * String#delete * String#delete_prefix * String#delete_suffix * String#downcase * String#dump * String#each/#each_line * String#gsub * String#ljust * String#lstrip * String#partition * String#reverse * String#rjust * String#rpartition * String#rstrip * String#scrub * String#slice! * String#slice/#[] * String#split * String#squeeze * String#strip * String#sub * String#succ/#next * String#swapcase * String#tr * String#tr_s * String#upcase This also fixes a bug in String#swapcase where it would return the receiver instead of a copy of the receiver if the receiver was the empty string.

This modifies the following String methods to return String instances
instead of subclass instances:

* String#*
* String#capitalize
* String#center
* String#chomp
* String#chop
* String#delete
* String#delete_prefix
* String#delete_suffix
* String#downcase
* String#dump
* String#each/#each_line
* String#gsub
* String#ljust
* String#lstrip
* String#partition
* String#reverse
* String#rjust
* String#rpartition
* String#rstrip
* String#scrub
* String#slice!
* String#slice/#[]
* String#split
* String#squeeze
* String#strip
* String#sub
* String#succ/#next
* String#swapcase
* String#tr
* String#tr_s
* String#upcase

This also fixes a bug in String#swapcase where it would return the
receiver instead of a copy of the receiver if the receiver was the
empty string.

Some string methods were left to return subclass instances:

* String#+@
* String#-@

Both of these methods will return the receiver (subclass instance)
in some cases, so it is best to keep the returned class consistent.
