Looking for an ANSI Control Character header

Looking for an ANSI Control Character header

[Kevin Ingwersen]

Hello!

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

"win32" is far too vague a heading.  How about using one of the current 
widely used Windows ports of termcap or ncurses (cygwin, MinGW, ....)

Termcap looks interesting, but I can not find anything about the control characters I would like to use.
I am trying to find a library that’d give me the right escape sequence - or a function - to do certain things. Such as
- Deleting everything from the left/right of the curser
- Erasing a whole line, setting the cursor to the beginning of the line
- Starting / ending a color sequence
i know that ncurses can do the color part, but I couldn’t find any way to make it print soemthing like "\x1b[1K“ for me. I know, that on some terminals, the \x expects an octal value rather than a hexadecimal value. (i.e. \x033 vs. \x1b). So the library I am looking for just needs to give me the right sequence to use o.o
Do you know any?

As far as I know, there is nothing else but curses/ncurses that can do that.

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.

I think you are out of luck for Windows. 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.
