 [REQUEST] terminal view for CAS mode - Printable Version +- HP Forums (https://www.hpmuseum.org/forum) +-- Forum: HP Calculators (and very old HP Computers) (/forum-3.html) +--- Forum: HP Prime (/forum-5.html) +--- Thread: [REQUEST] terminal view for CAS mode (/thread-7318.html) [REQUEST] terminal view for CAS mode - compsystems - 11-26-2016 09:30 PM Hello hp-prime community The current terminal view was created for numerical mode (HOME MODE), for this reason the output expressions are not symbolic. The numerical results, do not need readable printing. For those we program in CAS MODE we need or require PRETTY PRINT A comparison of the view & a practical example simplify flag: off increasing flag: off cas mode: on Script on history view PHP Code: `assume(a>0);(a*x^2+b*x+c) = 0;Ans*4*a;         // ((a*x^2+b*x+c)*4*a) = 0expand(Ans);     // (4*a^2*x^2+4*a*b*x+4*a*c) = 0Ans+b^2;         // (4*a^2*x^2 +4*a*b*x + 4*a*c+b^2 ) = (b^2)Ans-4*a*c;       // (4*a^2*x^2+4*a*b*x+4*a*c+b^2-4*a*c) = (b^2-4*a*c)simplify(Ans);   // (4*a^2*x^2+4*a*b*x+b^2) = (-4*a*c+b^2)  factor(Ans);     // (2*a*x+b)^2) = (-4*a*c+b^2)√(Ans);          // (abs(2*a*x+b)) = (√(-4*a*c+b^2))assume(b>0);assume(c>0);expr(replace(string(Ans),"abs","")); // (2*a*x+b) = (√(-4*a*c+b^2))Ans-b;           // (2*a*x+b-b) = (√(-4*a*c+b^2)-b)simplify(Ans);   // (2*a*x-b) = (√(-4*a*c+b^2)-2*b)Ans/(2*a);       // (2*a*x/(2*a)) = (-b+√(-4*a*c+b^2))/(2*a)simplify(Ans);   // x = (-b+√(-4*a*c+b^2))/(2*a)part(Ans,1)=reorder(part(Ans,2),[b,a,c]);  // x = (-b+√[b^2-4*a*c])/(2*a)expr(replace(string(Ans),"-b+","-b-")); // x = (-b-√[b^2-4*a*c])/(2*a) ` CAS prgm PHP Code: `#cas    deductionQuadformula():=    begin        local equation;        assume(a>0);        print; // Clear Terminal Window        print( "Use cursor keys ↑↓ to move the output screen" );        print( "Another key to continue after PAUSE" );        print( "" );        print( "[PAUSE]" ); wait();        print; // Clear Terminal Window again        print( "***** Deduction Quadratic Formula *****" ); // Title        print( "" );        equation:= (a*x^2+b*x+c) = 0;         print( string( equation ) );        print( "" );            print( "Ans*4*a" );            equ := equ * 4*a;         // ((a*x^2+b*x+c)*4*a) = 0             print( string( equ ) );            print( "" );                        print( "expand(Ans)" );            equ := expand( equ );     // (4*a^2*x^2+4*a*b*x+4*a*c) = 0            print( string( equ ) );            print( "" );            print( "Ans+b^2" );                equ := equ + b^2;         // (4*a^2*x^2 +4*a*b*x + 4*a*c+b^2 ) = (b^2)            print( string( equ ) );            print( "" );            print( "Ans-4*a*c" );                equ := equ - 4*a*c;       // (4*a^2*x^2+4*a*b*x+4*a*c+b^2-4*a*c) = (b^2-4*a*c)            print( string( equ ) );            print( "" );            print( "simplify(Ans)" );                equ := simplify( equ );   // (4*a^2*x^2+4*a*b*x+b^2) = (-4*a*c+b^2)              print( string( equ ) );            print( "" );            print( "factor(Ans)" );                equ := factor( equ );     // (2*a*x+b)^2) = (-4*a*c+b^2)            print( string( equ ) );            print( "" );            print( "√(Ans)" );             assume( b>0 ); assume( c>0 );            equ := √( equ );          // (abs(2*a*x+b)) = (√(-4*a*c+b^2)) // Should not show ABS            print( string( equ ) );            print( "" );            // patch            equ := expr( replace( string( equ ), "abs", "" ) ); // (2*a*x+b) = (√(-4*a*c+b^2))            print( string( equ ) );            print( "" );            print( "Ans-b" );                equ := equ - b;           // (2*a*x+b-b) = (√(-4*a*c+b^2)-b)            print( string( equ ) );            print( "" );            print( "simplify(Ans)" );                equ := simplify( equ );   // (2*a*x-b) = (√(-4*a*c+b^2)-2*b)            print( string( equ ) );            print( "" );            print( "Ans/(2*a)" );                  equ := equ / ( 2*a );       // (2*a*x/(2*a)) = (-b+√(-4*a*c+b^2))/(2*a)            print( string( equ )  );            print( ""  );            print( "simplify(Ans)"  );                equ := simplify( equ );   // x1 = (-b+√(-4*a*c+b^2))/(2*a)            equ := expr( replace( string( equ ), "x", "x1" ) );            print( string( equ )  );            print( ""  );            print( "expr(replace(string(equ),"-b+","-b-"))" );            equ1 := expr( replace( string( equ ), "-b+", "-b-" ) ); // x2 = (-b-√[b^2-4*a*c])/(2*a)             equ1 := expr( replace( string( equ1 ), "x1", "x2" ) );                print( string( equ1 )  );             print( "[PAUSE]"  ); wait( );                return "done";    end;#end ` Survey: Do you really need a new terminal view with pretty print?

Please vote, Thanks I don't need one. What I need is a terminal that works like a terminal with ANSI escape sequences. One that allows printing just as a physical terminal would. Tom L
