R – NSLog not printing to terminal

command lineconsolenslogobjective cterminal

Ok, so I've been using NSLog in objective-C for awhile now to debug and I know it's supposed to print to the terminal whatever I put in the parentheses. For some reason, it just stopped printing to the terminal and I'm not sure how to fix this error. I was wondering what other people would suggest doing to fix this problem. I've only included part of my code because I don't want to scare away someone from answering this simple (or at least I hope it's simple to fix) problem. When I run the code, the only two statements that print are "serverButton – Stage 1" and "serverButton – Stage 2 – Complete" but nothing else in between. FYI -(void)startServer is in another class called "Server" and I have made "server" a pointer to that said class.

-(IBAction)serverButton {
NSLog(@"serverButton - Stage 1");
[server startServer];
NSLog(@"serverButton - Stage 2 - Complete");
}

-(void)startServer {
    NSLog(@"serverButton - Stage 1");

    memset(&hints, 0, sizeof hints);
    hints.ai_family = AF_UNSPEC; // set to AF_INET to force IPv4
    hints.ai_socktype = SOCK_DGRAM;
    hints.ai_flags = AI_PASSIVE; // use my IP

    if ((rv = getaddrinfo(NULL, MYPORT, &hints, &servinfo)) != 0) {
        NSLog(@"ERROR: serverButton - Stage 1");
        fprintf(stderr, "getaddrinfo: %s\n", gai_strerror(rv));
        serverError = 1;
        NSLog(@"Error");
    }

Add a check to make sure server is not nil before you call startServer, if it was nil then nothing would get called and no error would be generated.

Out of the box you can use the quite bizarre Esc+F to move to the beginning of the next word and Esc+B to move to the beginning of the current word.

Python – How to print colored text to the terminal

This somewhat depends on what platform you are on. The most common way to do this is by printing ANSI escape sequences. For a simple example, here's some Python code from the Blender build scripts:

class bcolors:
    HEADER = '\033[95m'
    OKBLUE = '\033[94m'
    OKCYAN = '\033[96m'
    OKGREEN = '\033[92m'
    WARNING = '\033[93m'
    FAIL = '\033[91m'
    ENDC = '\033[0m'
    BOLD = '\033[1m'
    UNDERLINE = '\033[4m'

To use code like this, you can do something like:

print(bcolors.WARNING + "Warning: No active frommets remain. Continue?" + bcolors.ENDC)

Or, with Python 3.6+:

print(f"{bcolors.WARNING}Warning: No active frommets remain. Continue?{bcolors.ENDC}")

This will work on unixes including OS X, Linux and Windows (provided you use ANSICON, or in Windows 10 provided you enable VT100 emulation). There are ANSI codes for setting the color, moving the cursor, and more.

If you are going to get complicated with this (and it sounds like you are if you are writing a game), you should look into the "curses" module, which handles a lot of the complicated parts of this for you. The Python Curses HowTO is a good introduction.

If you are not using extended ASCII (i.e., not on a PC), you are stuck with the ASCII characters below 127, and '#' or '@' is probably your best bet for a block. If you can ensure your terminal is using a IBM extended ASCII character set, you have many more options. Characters 176, 177, 178 and 219 are the "block characters".

Some modern text-based programs, such as "Dwarf Fortress", emulate text mode in a graphical mode, and use images of the classic PC font. You can find some of these bitmaps that you can use on the Dwarf Fortress Wiki see (user-made tilesets).

The Text Mode Demo Contest has more resources for doing graphics in text mode.
