Bug #11989

Updated by nobu (Nobuyoshi Nakada) over 6 years ago

It is clear that the dedenting <<~HEREDOC feature was intended to only consider actual whitespace in the source file as indentation, not any escaped whitespace. E.g.: 

 ~~~ruby ~~~ 
 p <<~"E" 
   \ x 
    y 
 E 
 ~~~ 

 It prints `" x\n y\n"`. So `"\ "` does not count as whitespace. There is even an MRI test for this. 

 However, this case is handled differently: 

 ~~~ruby ~~~ 
 p <<~"E" 
   x\n     y 
 E 
 ~~~ 

 It prints `"x\n y\n"`. So `"\n"` is counted as whitespace, like an actual newline would be. I think it should print `"x\n     y\n"`.
