+#+title: Notes
+* part 2.
+how would i even try to check of 'in' or 'out' of the loop?
+i guess i could mark things while i go through the loop?
+
+or, i could count manually?
+
+i could change neighbors of the beast point.
+then do one more pass around, setting bool 'onMainPath' to true
+and then change all else to .
+
+i guess i could then do one more pass, and mark as 'I' and 'O' closest line of .
+
+another idea i don't really want to pursue - 'color fill from some corner'
+this is also painful due to pipes touching still need to let the 'O' filling in.
+
+but yeah, if i make initial filling in of the I, then i could just fill in all . with I until nothing changes.
+and count I
+
+sounds like a plan
+** allright, i found main path, display all not on main path as ' '
+and the thing is a mess
+
+i don't know how to select a point to mark as 'I'
+
+but! if i select a point to mark as 'O'
+and then go around the main path, marking things on the side as 'O'
+then i would be able to fill in all which are neighbors of 'O' as 'O'
+and that would leave only 'I' to be counted
+
+so.
+
+how would i monitor consistent 'side' of the pipe during the walkhrough?
+if we go down - we color as 'O' one down.
+if we go angle - color two - one down and one to the right.
+and only color if it's not already on main path.
+
+i suppose so
+** so a new method for initial pass of 'O'
+well, i'll need access to the direction, in which the neighbor is taken?
+nooo. not direction, but the symbol. ok, this is easier
+
+but i'll need to mutate the field
+
+no, i do need direction.
+
+ok, let's go lunch maybe, and maybe it will be a place with a power outlet as well
+** all is bad.
+i guess my model is unfit.
+
+what if. i had only 'forward' movement,
+and then Next would sometimes return 'forward', and sometimes 'right', 'forward'
+
+then.
+i'll need to store current directoin,
+have function to rotate it.
+
+and do 'forward' on coords based on the current direction
+
+and that would be NextPathCell()
+
+but from same how would i distinguish between being on top or bottom for -J
+i'll need to remember whether outer is to the 'left' or 'right' of the path
+and then if path turns into outer - just turn, don't do 'forward'
+and if path torns out of outer - do "big turn"
+
+maybe there's an easy check here?
+if path
+** and one more idea.
+i could do without 'walking' the outer pointer.
+i could mark all outer around the path element.
+based on where the outer is located
+and there are two possibilities.
+i could even maybe mark them as 3x3
+
+i stay on the path element.
+i check what are the 'O' in it's 3x3
+and fill in other of same area as 'O' and move on to next
+
+yeah, i think i like that.
+
+i will have a function that takes the path element.
+select the template
+then go through 3x3 around the path element, if sees element with .isOuter == true saves the name of the area,
+then for each found out area mark them all as 'O'
+

+.⌝A
+B.A
+
+AAA
+A⌜.
+A.B
+
+i guess i could just code that.
+** it also doesn't work. pipes to into place where whole 3x3 is path pipes and info on 'outer' is lost
+** will it work to cound intersections between a point and Top \ Left direction?
+** hypothesis - from the point, count up, down, left & right - intersections with the golden path.
+if into U&D or L&R both are odd - then inside.
+short circuit - if into 1 direction number is 0 - definitely outside
+
+and that's square? could kube? well, there shouldn't be too many points without the pipe already
+
+maybe i can somehow count for the whole map?
+
+if element on path - increase by 1 value from top
+*** also, what if i could consturct couter example before i start coding, you know
+with the point that is outside, but has odd in two sides?
+
+yes, i think there's a counter example with a point which has 3 on all sides because of path going directly to that side
+but maybe we don't count that as 'crossing'? only if we what? cross non-parallel line?
+
+that could be it
+** ok, last idea, yes, count intersections
+one additonal [][]int
+from top to bottom. take value from top, if it's pipe (and doesn't have down movemnt) increase by 1
+if it's not on path and has Even number, already count as Outer
+** oh, come on .
+
+7
+|
+L is 1
+
+but
+7
+|
+J is 0
+
+how to account for that?
+monitor the left and right somehow.
+have another map, store left or right in previous cell if we are in top thingy?
+
+if we're on path, and previous is empty - store left or right?
+so, copy previous
+
+and if we're counting up - store nothing.
+
+or just monitor angles?
+maybe have stack? of seen path elements?
+and some elements take off?
+** ok, one more attempt?
+not counting, but maintaining a stack?
+and opposite angles take the element off the stack?
+
+so - takes off -
+and any left braket takes off any right bracket
+
+and two bottom angles shouldn't be allowed to counteract one another, but top & bottom should be balanced anyway
+** uh. so many more updates.
+and i'll need to owerwrite S to it's value somehow
+
+i will change the S myself. by hardcode
