Any options for better interactive terminal-style I/O?

[compsystems]

Hello, this is a very requested requirement, I do not know what is the difficulty of incorporating it, hardware?

The first step is to include xcas printf cmd

An example of code between HP-PRIME_XCAS and XCAS, notice how difficult and ugly/primitive it is to read mathematical expressions in 1D

XCAS HPPRIME CODE

PHP Code:

#cas
    terminalViewTest():=
    begin
        local x, y;
        assume( x, symbol ); 
        assume( y, symbol );
        autosimplify(nop);
        DispG; 
        ClrIO; 
        print( "Terminal View, 2D printing" );
        
        print( "" );      
        print( "Expr0:" );
        print( (x^3-6*x^2+11*x-6 | x=y) + (x^4-x^3-6*x^2+11*x-6)/x^6);
        
        print( "" );
        print( "Expr1:" ); print( "" ); f(x):=x^3-2*x^2+1*x-1;
        print( 'f(x)' ); print( "" );
        print( f(x) );print( "" );
        
        print( "" );
        print( "Expr2:" ); print( "" );
        print( 'f(x) | x=y' ); print( "" );
        print( 'x^3-2*x^2+1*x-1 | x=y' ); print( "" );
        print( f(x) | x=y ); print( "" );
        print( 'f(y)' ); print( "" );
        print( f(y) ); print( "" );
        
        print( "" );
        print( "Expr3:" ); g(x):=1/(x+3);
        print( 'g(x)' ); print( "" );; 
        print( g(x) );  print( "" );
   
        print( "" );     
        print( "Expr4:" );
        print( 'f(g(x))' ); print( "" ); 
        print( f(g(x)) ); print( "" );

        print( "" );     
        print( "Expr5:" );        
        print( 'g(f(x))' ); print( "" );
        print( g(f(x)) ); print( "" );
        
        return "Done";
    end;
#end

Is anyone else interested in having a better terminal view?
