I write a function like this:
function InsertNumber(start, end, step)
let i = a:start
let curr_line = 0
while i <= a:end
if a:step <= 0
echo "Error: step cannot <=0."
break
endif
call append(curr_line, i)
let i += a:step
let curr_line += 1
endwhile
endfunction
when I call this function, I type this:
:echo InsertNumber(8,10,1)
8
9
10
1) How can I give arguement "step" a default value(eg: 1) when define the
function?
like a C function:
void C_func(int a, int b_have_default_val = 1)
{
;
}
2)
I want to print number like this, how to do it?
