Inconsistent line ending from `@raw_str` in Windows

[korsbo]

A raw-string is normally parsed to have Linux-style line endings, \n, even on Windows. Great! However, you get Windows-style line endings, \r\n, if the linebreak in the raw-string is preceded by a backslash.

julia> raw"foo\bar
baz"
"foo\\bar\nbaz"   # linux line-ending, \n

julia> raw"foo\
bar
baz"
"foo\\\r\nbar\nbaz"   # windows style line-ending, \r\n, followed by linux style.

I can't reproduce this

May depend on what kind of line endings your editor saves the file with. Might be possible to reproduce by printing and parsing directly in Julia. I also suspect it doesn't only happen on Windows, that's just the only platform where editors produce \r line endings.

Yup:

julia> eval(Meta.parse("""raw"foo\\\rbar\rbaz\""""))
"foo\\\rbar\nbaz"
