Multiple line datum #12

Open sorawee opened 3 years ago

sorawee commented 3 years ago

Multiple line datum should be fully counted.

For example:

"abc
def
ghi
jkl
mno"

should be counted as 5 lines. Currently, it counts only 1.

Similarly:

(define |a
  b
  c
  d
  e|
  1)

should be counted as 6 lines. Currently, it counts only 2.

This is probably not fixable for syntax-sloc, due to the limited information of source location in syntax object, but for files, we should be able to use the span information to count the lines properly.

Source Location in syntax objects does contain span information, but that's span in position, not span in lines, so I'm not sure how that would help.

sorawee commented 3 years ago

If you have the actual file, you can read the file and move by the position span to get to the ending line.

Maybe an entirely different approach using lexer output instead of syntax objects, but if I make that it would probably be an entirely different repository
