I'm working on a simple cli script and wanted to add some color to the following code: rl.question('Enter destination path: ', function(answer) { // ... }); rl.write('/home/' + user + '/bin'); Which displays in the terminal: Enter destination path: /home/jmcateer/bin_ But I wanted to add some color to the prompt I did the following: rl.question('\u001b[1;36mEnter destination path:\u001b[0m ', function(answer) { }); rl.write('/home/' + user + '/bin'); And the command line prompt ended up displaying: Enter destination path: /home/jmcateer/bin_ It works but there's a huge amount of white space I

Where can I find the latest ANSI C standard document? You can buy it here (ISO/IEC 9899:2011): http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=57853 Price is around USD 240. You can also get the latest (April 12, 2011) draft version for free: http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf UPDATE (June 16, 2016): C11 has also been ratified by ANSI. The ANSI store is selling C11 document (essentially the same document as the ISO one) for a cheaper price: USD 60 (as of June 16, 2016). ISO store also lowered their price for C11, from CHF 238 to CHF 198

I am writing a program in C that prints a random hexadecimal value to a text file. The printed value has a carriage return (CR) along with a line feed (LF). However, the CR (visible in notepad++) is causing issues when the file is used. Is there a way to print a new line with just the LF and no CR. This is the code: #include <stdio.h> #include <stdlib.h> void main(){ int hexa_address, numberofAddress; char tracefile[50]; //name of file int seq_or_rand; //1 for random address; 2 for sequential address srand(time(NULL)); //reset the value of the random printf("This generator generates 32bits

Is it possible to use Windows API ANSI functions with UTF-8 strings? For example, say I have a path encoded in UTF-8. Can I call CreateDirectoryA or CreateFileA and use a UTF-8 path, or do I have to perform some conversion before calling the functions? No. Use MultiByteToWideChar to convert UTF-8 to UTF-16 and then call the wide character APIs such as CreateDirectoryW or CreateFileW . An easier approach (than using raw Win32 API MultiByteToWideChar) would be to use ATL conversion helpers , like CA2CW . You can specify CP_UTF8 as code page (second parameter in the constructor), to convert from

I need to extract the text between 2 string patterns in c. Example: aaaaaa<BBBB>TEXT TO EXTRACT</BBBB>aaaaaaaaa PATTERN1=<BBBB> PATTERN2=</BBBB> Thanks. Here is an alive example of how to do this #include <stdio.h> #include <string.h> int main(void) { const char *s = "aaaaaa<BBBB>TEXT TO EXTRACT</BBBB>aaaaaaaaa"; const char *PATTERN1 = "<BBBB>"; const char *PATTERN2 = "</BBBB>"; char *target = NULL; char *start, *end; if ( start = strstr( s, PATTERN1 ) ) { start += strlen( PATTERN1 ); if ( end = strstr( start, PATTERN2 ) ) { target = ( char * )malloc( end - start + 1 ); memcpy( target, start,

I have to write a script that support reading of a file which can be saved as either Unicode or Ansi (using MS's notepad). I don't have any indication of the encoding format in the file, how can I support both encoding formats? (kind of a generic way of reading files with out knowing the format in advanced). MS Notepad gives the user a choice of 4 encodings, expressed in clumsy confusing terminology: "Unicode" is UTF-16, written little-endian. "Unicode big endian" is UTF-16, written big-endian. In both UTF-16 cases, this means that the appropriate BOM will be written. Use utf-16 to decode such

I have a Ruby script that generates a UTF8 CSV file remotely in a Linux machine and then transfers the file to a Windows machine thru SFTP. I then need to open this file with Excel, but Excel doesn't get UTF8, so I always need to open the file in a text editor that has the capability to convert UTF8 to ANSI. I would love to do this programmatically using Ruby and avoid the manual conversion step. What's the easiest way to do it? PS: I tried using iconv but had no success. ascii_str = yourUTF8text.unpack("U*").map{|c|c.chr}.join assuming that your text really does fit in the ascii character set

This question already has an answer here: Recommended gcc warning options for C [closed] 15 answers What GCC options should be set to have GCC as strict as possible? (and I do mean as strict as possible) I'm writing in C89 and want my code to be ANSI/ISO compliant. Jonathan Leffler I'd recommend using: -Wall -Wextra -std=c89 -pedantic -Wmissing-prototypes -Wstrict-prototypes \ -Wold-style-definition You should compile with -O as well as -g as some warnings are only available when the optimizer is used (actually, I usually use -O3 for spotting the problems). You might prefer -std=gnu89 as that
