Relative paths are relative to current working directory. If you do not want your path to be relative, it must be absolute. But there is an often used trick to build an absolute path from current script: use its __file__ special attribute: from pathlib import Path path = Path(__file__).parent / “../data/test.csv” with path.open() as f: … Read more
The program will not work properly because at Line 1, when the user presses Enter, it will leave in the input buffer 2 character: Enter key (ASCII code 13) and \n (ASCII code 10). Therefore, at Line 2, it will read the \n and will not wait for the user to enter a character. The … 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
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
As a general rule you write something like this: do x <- somethingThatReturnsIO somethingElseThatReturnsIO $ pureFunction x There is no way to get the “Int” out of an “IO Int”, except to do something else in the IO Monad. In monad terms, the above code desugars into somethingThatReturnsIO >>= (\x -> somethingElseThatReturnsIO $ pureFunction x) … Read more
The simplest way to do this would be to read it using regular file paths. On Windows: new File(“\\\\server\\path\\to\\file.txt”) // (double-backslashes required for backslashes in path) On Unix: First mount the share using Samba (SMB, NFS or whatever other protocol) to some location like /mnt/network. Then you can use: new File(“/mnt/network/path/to/file.txt”) Once you have the … Read more
You could use a generator: def myreadlines(f, newline): buf = “” while True: while newline in buf: pos = buf.index(newline) yield buf[:pos] buf = buf[pos + len(newline):] chunk = f.read(4096) if not chunk: yield buf break buf += chunk with open(‘file’) as f: for line in myreadlines(f, “.”): print line
This will add the line where you want it. (Make sure you have using System.IO; and using System.Linq; added) public void CreateEntry(string npcName) //npcName = “item1” { var fileName = “test.txt”; var endTag = String.Format(“[/{0}]”, npcName); var lineToAdd = “//Add a line here in between the specific boundaries”; var txtLines = File.ReadAllLines(fileName).ToList(); //Fill a list … 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
