ASCII Box rendering

Question

Task

Your task is to write a program that will output ASCII boxes at the locations specified by the input.

Input

You will be given a list of numbers. The format here is a bit flexible, in that you can use any deliminator you want (e.g. 1,2,3,4, 1 2 3 4, [1,2,3,4]). The list is in groups of 4 and specifies the xywh of each box. The width and height of each box will be at least 2. x and width are left-to-right. y and height are top-to-bottom.

Output

Rendering can be thought of as right to left, with the box on the right drawn first, and every box after that is over it. Trailing spaces are allowed, as well as one trailing newline.

How to handle overlapping boxes

The box on the left of the input is the top box, and nothing will overlap it. Every box after it is rendered only in the space that is not contained in a box already and will not replace the border of a already rendered box.

Style

The style of the boxes are fairly standard, with + used for corners, - used for horizontal lines, and | used for vertical lines.

Examples:

(>>> denotes input)

>>>0 0 11 4 7 2 8 4 3 5 8 3

This is a function that takes an array of arrays and returns a character matrix.

Tests:

      t1← (0 0 11 4)(8 2 8 4)(3 5 8 3)

Explanation:

• ⎕IO←0: set the index origin to 0.
• Create a matrix of the right size:
  • ⌈⌿↑⍵: find the largest values for x, y, w, and h
  • +⌿2 2⍴: x+w and y+h
  • K←' '⍴⍨⌽: make a matrix of x+w*y+h spaces and store it in K.
• Draw the boxes into it:
  • {...}¨⌽⍵: for each of the boxes, in reverse order,
    • x y W H←⍵-⌊.5×⍳4: assign the coordinates to x, y, W, and H, and subtract 1 from both W and H. (coordinates are exclusive, APL array ranges are inclusive.)
    • K[Y←y+⍳H;X←x+⍳W]←' ': fill the current box with spaces
    • K[Y;A←x+0 W]←'|': draw the vertical sides
    • K[B←y+0 H;X]←'-': draw the horizontal sides
    • K[B;A]←'+': set the edges to '+'
  • K⊣: afterwards, return K.

Accepts an array of arrays of coordinates and returns a string.

a=>a.reverse().map(([x,y,w,h])=>[...Array(y+h)].map((_,i)=>(s=r[i]||'',r[i]=i<y?s:(s+' '.repeat(x)).slice(0,x)+(c=>c[0]+c[1].repeat(w-2)+c[0])(y-i&&y+h-1-i?'| ':'+-')+s.slice(x+w))),r=[])&&r.join`\n`

Where \n represents a newline character.

Edit: Saved 5 bytes by reversing my conditions. Saved a further 6 bytes by switching from an array of char arrays to an array of strings. Saved a further 9 bytes by introducing a temporary variable. Saved a further 7 bytes by introducing a helper function. Saved a further 3 bytes by undoing a previous saving!

v=w-2
h.times{|i|a[y+i][x,w]=i%~-h<1??++?-*v+?+:?|+' '*v+?|}
)while n[0]
a.delete($b);puts a}

Ungolfed in test program

f=->n{                                #worst case width when x=w=large number, is max input*2+1

Screenshots (cropped)

Explanation

DEF B A 'make a function and add 12 bytes :(
 WHILE LEN(A) 'repeat until array is empty
  H=POP(A):W=POP(A)-2 'get width/height
  Y=POP(A):X=POP(A) 'get x/y
  FOR I=0 TO H-1 'draw one row at a time
   LOCATE X,Y+I 'position the cursor
   PRINT "+|"[M]; 'draw left edge
   PRINT "- "[M]*W; 'draw middle
   PRINT "+|"[M] 'draw right edge
   M=I<H-2
  NEXT
 WEND
END

M stores whether it's on the first/last row of the box (0=+--+, 1=| |). On the first pass through the loop, M is 0, and on all others until the last, it's 1.
