如何使用CSSLint？

Question

I found some command line arguments to run generate the CSSLint report in xml format. It is working fine while running through command prompt.

Arguments:

csslint --format=csslint-xml "{SourceDir}\\bootstrap.css" > "C:\\temp\\csslint.xml"

I want to execute it through C# application. I tried the below code.

Process process = new Process()
{
    StartInfo =
    {
        FileName = "cmd.exe",
        Arguments = "csslint --format=csslint-xml " + @"""{SourceDir}\bootstrap.css""" + @" > ""C:\Temp\CssLint.xml""",
        UseShellExecute = false,
        RedirectStandardOutput = true,
        CreateNoWindow = true,
    }
};

process.Start();
process.WaitForExit();

But it is not working. Can i have a solution or idea for this issue?

Also is there any way to generate the CSSLint report for the specified directory? I want to give the directory path instead of file name.

You need to add /K or /C to cmd to execute a process passed as a parameter, thus:

Arguments = "/C csslint --format=csslint-xml " + @"""{SourceDir}\bootstrap.css""" + @" > ""C:\Temp\CssLint.xml""",

From the documentation :

Options

/C Run Command and then terminate

/K Run Command and then return to the CMD prompt. This is useful for testing, to examine variables

One caveat... the piping (the > "C:\\temp\\csslint.xml" part of your command line) is not an argument, it's a redirection.

If you are redirecting your stdout (the RedirectStandardOutput = true ) from your app, you can capture it directly from C#, no need to pipe it to a file like you are trying to do: you'd need to handle the Process.OutputDataReceived event between your Start and WaitForExit calls, or read from the Process.StandardOutput stream).

As for your second question, the csslint CLI allows passing in a directory instead of a file
