[ruby-core:85989] [Ruby trunk Bug#14584] Squigly heredoc with interpolation that has a string literal withe spaces gets incorrect value

Issue #14584 has been updated by sikachu (Prem Sichanugrist).


👍 I can confirm this bug exists in 2.5.0p0.

Also, it seems like the number of spaces it's removing is based on the gutter size as well (which is expected?)

~~~ ruby
# two spaces gutter, four leading spaces in literal
<<~FOO
  two#{"    four    "}
FOO
#=> "two  four    \n"

# two spaces gutter, five leading spaces in literal
<<~FOO
  two#{"     five     "}
FOO
#=> "two   five     \n"

# three spaces gutter, five leading spaces in literal
<<~FOO
   three#{"     five     "}
FOO
#=> "three  five     \n"
~~~

I don't have enough Ruby lexer knowledge to fix this, so I hope someone will be able to spare their time taking care of this 🙇‍♂️

Bug #14584: Squigly heredoc with interpolation that has a string literal withe spaces gets incorrect value

----------------------------------------
Given this program:

~~~
text1 = <<~FOO
  one#{"   two   "}
  FOO

text2 = <<~FOO
one#{"   two   "}
FOO

p text1
p text2
~~~

The output is:

~~~
"one two   \n"
"one   two   \n"
~~~

The two should be equal.

I think the problem happens because squigly heredoc will remove the first two spaces from each line in the heredoc, but it seems to also be removing it from literals inside interpolation inside a heredoc.
