Bug #3574

Missing documentation for sprintf named argument support

Added by Heesob Park about 5 years ago. Updated over 4 years ago.

ruby -v:ruby 1.9.3dev (2010-07-15 trunk 28645) [i386-mswin32_90] Backport:


I noticed that sprintf supports named argument since 1.9.1.

But I cannot find any documentation about sprintf named argument support.

In my test, named argument works like this:

sprintf("%s %d %{first} %{second}",{:first=>'hello',:second=>8}) #=> "hello 8 hello 8"
