How can I determine if a char* is a windows line ending?


How can I determine if a char* is a windows line ending?

Hope this helps Windows line endings consist of two separate characters, a carriage return ('\r') immediately followed by a newline ('\n'). Because they are a combination of two characters, you cannot detect them by looking at only one character at a time.
If your code is running on Windows and the file is supposed to be interpreted as text, then open it in text mode (for instance, "r" instead of "rb"), and the line terminators should be automatically translated to single newlines. If you're running on a system that uses single newlines as line terminators (most anything but Windows these days) then no such translation will be performed. In that case, to detect Windows-style line terminators you need to keep track of whether the immediately previous character was a '\r'. When that is so, and the next character read is a '\n', then you've detected a line terminator.

around this issue I have a bunch (hundreds) of files that are supposed to have Unix line endings. I strongly suspect that some of them have Windows line endings, and I want to programmatically figure out which ones do. , You could use grep
code :
egrep -l $'\r'\$ *

I wish this help you Notice that text files may have inconsistent line endings. Your program should not choke on that. Using ReadLine on a StreamReader (and similar methods) will take care of any possible line ending automatically.
If you manually read lines from a file, make sure to accept any line endings, even if inconsistent. In practice, this is quite easy using the following algorithm:

To fix the issue you can do To detect \n and \r\n line endings, simply match the first line against the regular expression /\r?\n$/:
code :
def determine_line_ending(filename)
  File.open(filename, 'r') do |file|
    return file.readline[/\r?\n$/]
  end
end

determine_line_ending('./windows_file.csv')
# => "\r\n"

determine_line_ending('./unix_file.csv')
# => "\n"

I wish this helpful for you My build.gradle file contains the following: , Following works well:
code :
import org.apache.tools.ant.filters.FixCrLfFilter

processResources {
    filesMatching('**/*.sh') {
        filter(FixCrLfFilter.class,
        eol:FixCrLfFilter.CrLf.newInstance("lf"))
    }
    filesMatching('**/*.properties') {
        filter(FixCrLfFilter.class,
        eol:FixCrLfFilter.CrLf.newInstance("lf"))
    }
    filesMatching('**/*.xml') {
        filter(FixCrLfFilter.class,
        eol:FixCrLfFilter.CrLf.newInstance("lf"))
    }
}

I wish this helpful for you So I have a file that has mixed line endings. I need to remove only linux Line Feed (LF) but leave windows line endings alone(RFLF). Any quick bash one liner that can do this? , If you want to convert all line endings to Windows line endings:
