vt100

问题 I know this kind of questions are asked frequently, but I think this one is a little different and needed to be asked. The new Windows console supports ANSI (VT100) control codes: ANSI/VT100 control codes & Windows document: the control codes. However, ESC[2J doesn't really "clear" the screen, it just scrolls down to "hide" printed contents. Only ESC[H + ESC[J really "clears" the currently showed contents on the screen. Is this a bug or it is designed to do this? Is it written on some kind of

问题 I'm developing a library that needs to identify the running terminal emulator in order to output emulator-specific escape code sequences. For example, iTerm 2 uses the following proprietary sequence: ESC ] 50 ; CurrentDir=/path/to/dir BEL While ConEmu uses the following proprietary sequence: ESC ] 9 ; 9 ; C:\path\to\dir BEL Now, I need to query the terminal (either using environment variables or using an escape sequence) in order to output the correct terminal-specific codes. How can I

问题 I try to move the cursor in console. And I find out that vt100 code could do this. #include<stdio.h> int main() { printf("123456789\n"); printf("\033A"); printf("abcdefghi\n"); return 0; } Its output is not the same as planned. this is what the code above print in console. In the second line there's a small arrow before "A", it cant put on the web 123456789 Aabcdefghi How to use the vt100 code when programming in Visual Studio in Windows? 回答1: Not all Windows platforms support VT100. Only

问题 I am building a terminal window in a browser (sth. like ajaxterm) and don't know which escape sequence to send to ssh tunnel (opened via paramiko.SSHClient().invoke_shell(term='linux') ). I have found a key logger and tried it in a terminal with $TERM == 'linux', but it returns the same sequence for ctrl+left and left (27,91,68). If I try keylogger in another terminal (with $TERM == 'xterm') I get the codes (27,91,49,59,53,68). But these codes do not move generate the expected output from SSH

问题 Ncurses can colorize text but GNU utilities like ls and diff apparently colorize text without calling Ncurses. Can I, too, portably colorize text without calling Ncurses? For example, in C: printf("the word \033[32mgreen\033[0m is printed in color\n"); This works on my installation but does not look very portable. On the other hand, if ls and diff do it more or less in this way, then who am I to call the technique nonportable? Examining GNU sources, I notice that ls uses dircolors or $LS

问题 I'm implementing a vt100 terminal emulator in javascript and the vt100 spec (from man terminfo and infocmp ) tells me that smkx=\E[?1h\E= is the code to enter key-board transmit mode and rmkx=\E[?1l\E> is the code to leave 'key-board transmit' mode. I couldn't really understand what key-board transmit mode is. From http://vt100.net/dec/ek-vt220-tm-001.pdf, 7.4.4.1 Keyboard Transmit Mode -- The keyboard codes and a few other special codes are transmitted via a serial line output in PORT of the
