ruby - 如何阻止 Ruby 自动添加回车符

Question

我在从 Windows 机器构建要在 Linux 环境中读取的文本文件时遇到问题。

def test

    my_file = Tempfile.new('filetemp.txt')

    my_file.print "This is on the first line"
    my_file.print "\x0A"
    my_file.print "This is on the second line"

    my_file.close

    FileUtils.mv(my_file.path, "C:/Users/me/Desktop/Folder/test.usr")

end

0A 是换行的 ASCII 代码，但是当我在 Notepad++ 中打开生成的文件时，我看到它在行尾附加了 CR 和 LF .

如何仅添加换行符作为换行符？

Answer 1

尝试将输出分隔符 $\ 设置为 \n。

def test
    $\ = "\n"
    my_file = Tempfile.new('filetemp.txt')

    my_file.print "This is on the first line"
    my_file.print "This is on the second line"

    my_file.close

    FileUtils.mv(my_file.path, "C:/Users/me/Desktop/Folder/test.usr")

end

或者你应该可以使用#write，它不会添加输​​出分隔符

def test
    my_file = Tempfile.new('filetemp.txt')

    my_file.write "This is on the first line"
    my_file.write "\x0A"
    my_file.write "This is on the second line"

    my_file.close

    FileUtils.mv(my_file.path, "C:/Users/me/Desktop/Folder/test.usr")

end
