I have been trying to use control sequences like "\x1b[1K“ within my programs. But due to different terminals, and the fact that Win32 doesnt perfectly support ANSI control characters, I wanted to ask if there is somewhere a way one can archive this. The reason why i am asking here is, there is no such thing as an ncurses forum or so, where such question would be more right. Kind regards Ingwie ^ permalink raw reply [flat|nested] 5+ messages in thread

One possible approach is to parse terminfo's terminal specifications yourself. You have the choice of parsing the compiled binary files or the source files. However, if you succeed with the parsing, it is IMO non-trivial to actually utilize the information that you get; you will need interpreter of the terminal handling "instructions" as well. IOW, I have tried once the same as you are trying now but I have given up, when I was confronted with the size of the task. That said, by all means, try for yourself, maybe you are a lot more tenacious than I was. > > Am Mo.

If I remember right, for some "escape sequences" you actually need to perform function calls in order to get the win32 console do the requested action. My approach was to define myself the escape codes I used in a header with those macros set to the empty string for windows. OTOH, I never attempted to support every terminal. Too daunting for just the bit of console sugar I was adding. But the direction would indeed be parsing the terminfo files. ^ permalink raw reply [flat|nested] 5+ messages in thread
