how one can write a nice vector parser, something that does pgfvecparse{A=B-C; D=E x F;}
2
I am often use coordinates of points to draw figure in geometry. I know that, we can add, minus coordinates of points, example
begin{tikzpicture}
tkzDefPoints{0/0/C',3/0/D',1/1/B'}
coordinate (A') at ($(B')+(D')-(C')$);
end{tikzpicture}
If I have two points A(1,2,3) and B(4,5,6), how can I define vector AB as (B)-(A)?

If you use the coordinates only for drawing, simply define each components of points as variable and then define coordinate points using them. For example:
documentclass[margin=3.14159mm]{standalone}
usepackage{tikz,tikz-3dplot}
begin{document}
tdplotsetmaincoords{60}{125}
begin{tikzpicture}
[scale=0.9,
tdplot_main_coords,
axis/.style={-latex,thick},
vector/.style={-stealth,red,very thick},
vector guide/.style={dashed,thick}]
%standard tikz coordinate definition using x, y, z coords
% A(2,4,3), B(3,-1,4)
defAx{2}
defAy{4}
defAz{3}
defBx{-1}
defBy{3}
defBz{4}
coordinate (O) at (0,0,0);
coordinate (A) at (Ax,Ay,Az);
coordinate (B) at (Bx,By,Bz);
%draw axes
draw[axis] (0,0,0) -- (4,0,0) node[anchor=north east]{$x$};
draw[axis] (0,0,0) -- (0,4,0) node[anchor=north west]{$y$};
draw[axis] (0,0,0) -- (0,0,5) node[anchor=south]{$z$};
%Dot at point
fill [blue] (A) circle (2pt);
fill [blue] (B) circle (2pt);
%draw a vector from O to A and O to B
draw[vector guide] (O)node[left=1mm]{} -- (A)node[above=-1mm,right]{$P_1(Ax,Ay,Az)$};
draw[vector guide] (O) -- (B)node[above=-1mm,right]{$P_2(Bx,By,Bz)$};
%draw vector D=AB
draw[vector] (A) -- (B)node[midway,above,sloped]{$mathbf{D}$};
end{tikzpicture}
end{document}
