newline

问题 I have a textarea where the user can write up to 1000 characters. I need to get the jQuery('#textarea').val() and create an array where each item is a line of the textarea 's value. That means: This is a nice line inside the textarea. This is another line. (let's asume this line is empty - it should be ignored). Someone left more than 2 new lines above. Should be converted to a JavaScript array: var texts = []; text[0] = 'This is a nice line inside the textarea.'; text[1] = 'This is another

问题 This is a very basic concept, but something I have never been able to articulate that well. and I would like to try to spell it and see where I go wrong. If I have to, how would I define a "newline character". say if I create a new file in unix(or windows), then does the file store the "end of line" information by inserting a special character in the file called as "new line character". If so, what is its ascii value? I remember that in C programs, I have checked for the read character

问题 On Windows this #include <stdio.h> int main() { putc('A',stdout); putc('\r',stdout); putc('\n',stdout); } outputs A<CR><CR><LF> How to write just LF char to stdout without automatic conversion to CR LF? I need it to make simple socket stream reader to stdout. I've tried bcc32 from CodeGear, mingw, tinycc all yield same result, changing putc to putchar, fputc, fwrite doesn't help either. 回答1: The MSVC solution is: #include <io.h> #include <fcntl.h> ... _setmode(1,_O_BINARY) Other runtimes may

问题 What is the newline character in C? I know that different OS have different line-ending characters, but they get translated into the C newline character. What is that character? 回答1: It's \n . When you're reading or writing text mode files, or to stdin/stdout etc, you must use \n , and C will handle the translation for you. When you're dealing with binary files, by definition you are on your own. 回答2: The new-line may be thought of a some char and it has the value of '\n' . C11 5.2.1 This C

问题 I am using the following conditional statement to read from standard input. if ((n = read(0,buf,sizeof(buf))) != 0) When inputting data from standard input, generally the user presses enter when done. But read() considers '\n' as input too in which case n = 1 and the conditional doesn't evaluate to false. Is there a way to make the conditional evaluate to false when the user presses enter (without entering anything) on standard input apart from checking the contents of buf. Is there any other

问题 Is there any function that does what NSLog does but without the new line at the end? 回答1: see this http://borkware.com/quickies/one?topic=NSString excerpted from that page: void LogIt (NSString *format, ...) { va_list args; va_start (args, format); NSString *string; string = [[NSString alloc] initWithFormat: format arguments: args]; va_end (args); printf ("%s\n", [string UTF8String]); [string release]; } // LogIt just customize the printf to suit your needs 回答2: You can use printf(), but the

问题 I'm writing an Android app where I'm writing a file to disk with one data value per line. Later, such files can be read back into the app, and this simple data format is deserialized back into an array. At the moment, I'm delineating data values/lines in the serialization and deserialization code with \n . How does Android handle carriage returns and such line breaks? Can I use \n safely in this context? 回答1: Its better to use String lineSep = System.getProperty("line.separator"); 回答2: Yes,

问题 I want to create a string that spans multiple lines to assign to a Label Caption property. How is this done in Delphi? 回答1: In the System.pas (which automatically gets used) the following is defined: const sLineBreak = {$IFDEF LINUX} AnsiChar(#10) {$ENDIF} {$IFDEF MSWINDOWS} AnsiString(#13#10) {$ENDIF}; This is from Delphi 2009 (notice the use of AnsiChar and AnsiString). (Line wrap added by me.) So if you want to make your TLabel wrap, make sure AutoSize is set to true, and then use the

问题 So I think it may have to do with textmate, but we work in a small team and are having some issues with full-file conflicts of nearly identical files in git because each line of one branch has a ^M appended to it. What is this mysterious ^M character supposed to do, and where could it be coming from? Our developers use emacs on Windows/Mac, TextMate on Mac, coda on Mac, and occasionally the wp-admin text editor. Anybody ever have this issue stemming from one of those? 回答1: Someone is not

问题 I am hoping this is a simple one, though it seems it often isn't... I am working with XLST 1.0 and I have a string which I need to translate . This string is a user-entered text field. It contains several smaller strings separated by a delimiter. (In this case, it's "|".) The length of this string and the number of special characters varies widely. (This field is similar to a CSV list, however, rather than using a comma as the delimiter, the "|" is the delimiter.) I need to learn how to
