日記

今日は病院めぐり疲れた…また結果を聞きに市街にでないといけない．めんどくせぇ．

今日書いたコード

❯ ruby -e "File.open('multiline.txt') { |f|   pp f.readlines.join }"
"1\r2\n" + "3\r\n" + "4"
❯ cat multiline.txt | pbcopy

let str = """
1
2
3
4
"""
print(str)
print(str.unicodeScalars.map(\.value))

1
2
3
4
[49, 10, 50, 10, 51, 10, 52]

Line breaks in a multiline string literal are normalized to use the line feed character. Even if your source file has a mix of carriage returns and line feeds, all of the line breaks in the string will be the same. https://docs.swift.org/swift-book/ReferenceManual/LexicalStructure.html#ID412
