Here you go: use std::io::Read; use std::mem; use std::slice; #[repr(C, packed)] #[derive(Debug, Copy, Clone)] struct Configuration { item1: u8, item2: u16, item3: i32, item4: [char; 8], } const CONFIG_DATA: &[u8] = &[ 0xfd, // u8 0xb4, 0x50, // u16 0x45, 0xcd, 0x3c, 0x15, // i32 0x71, 0x3c, 0x87, 0xff, // char 0xe8, 0x5d, 0x20, 0xe7, … Read more
The Ruby IO documentation is not 100% clear on how this buffering works, but this is what you can extract from the documentation: Ruby IO has its own internal buffer In addition to that the underlying operating system may or may not further buffer data. The relevant methods to look at: IO.flush: Flushes IO. I … Read more
To read a text file with a specific encoding you can use a FileInputStream in conjunction with a InputStreamReader. The right Java encoding for Windows ANSI is Cp1252. reader = new BufferedReader(new InputStreamReader(new FileInputStream(csvFile), “Cp1252”)); To write a text file with a specific character encoding you can use a FileOutputStream together with a OutputStreamWriter. writer … Read more
How can I modify the test script above to avoid the error message when the script is run as shown (under Unix/bash)? You will need to prevent the script from writing anything to standard output. That means removing any print statements and any use of sys.stdout.write, as well as any code that calls those. The … Read more
It could well be a permission problem. From the documentation: The Exists method returns false if any error occurs while trying to determine if the specified file exists. This can occur in situations that raise exceptions such as passing a file name with invalid characters or too many characters, a failing or missing disk, or … Read more
To avoid changing your git config, you can enable colour just for the current command by passing a config variable with -c. For the status command, the variable is color.status: git -c color.status=always status | less -REX For diff, show, log and grep commands, the variable is color.ui: git -c color.ui=always diff | less -REX … Read more
For a text file just iterating over it with a for loop is almost always the way to go. Never mind about speed, it is the cleanest. In some versions of python readline() really does just read a single line while the for loop reads large chunks and splits them up into lines so it … Read more
This works pretty well for me. Hope I could help import javax.activation.MimetypesFileTypeMap; import java.io.File; class Untitled { public static void main(String[] args) { String filepath = “/the/file/path/image.jpg”; File f = new File(filepath); String mimetype= new MimetypesFileTypeMap().getContentType(f); String type = mimetype.split(“https://stackoverflow.com/”)[0]; if(type.equals(“image”)) System.out.println(“It’s an image”); else System.out.println(“It’s NOT an image”); } }
If the idea here is to understand how to read a file line by line then all you need to do is: with open(filename, ‘r’) as f: for line in f: print(line) It’s not typical to put this in a try-except block. Coming back to your original code there are several mistakes there which I’m … Read more
