This PR id due to a small bug that I pointed to @lenguyenthanh and @TonioGela when creating the tutorial.
Basically, calling
Files[IO].writeUtf8Lines(path)
will add a newline at the end of the written lines, regarding the number of elements of the collection. This will create a bug that, when usingFIles[IO].readlUtf8Lines(path)
will always add a new empty element to the compiled collection at the end.So this PR changes the behaviour of the
readLines
method so it ignores any empty characters after the last newline, similar if you dowc -l
on any file that has been written by theFiles#writeUtf8Lines
method.It introduces changes on tests, as well as in the documentation.
