# Draw an ASCII house

This is a window:

---
| |
---


Let's add some walls |. Put two spaces on either side of it so that the window has plenty of room.

|  ---  |
|  | |  |
|  ---  |


Now let's add a roof and a ceiling. To keep the window in the middle of the room, let's add one more row above it and below it.

---------
|       |
|  ---  |
|  | |  |
|  ---  |
|       |
---------


Now, just add a roof. Put a slash as far left as possible, and a backslash as far right as possible, and we have this:

/       \
---------
|       |
|  ---  |
|  | |  |
|  ---  |
|       |
---------


Then move the slash up one and right one. Move the backslash up one and left one:

 /     \
/       \
---------
|       |
|  ---  |
|  | |  |
|  ---  |
|       |
---------


Repeat until the two slashes meet, then add an asterisk where they meet:

    *
/ \
/   \
/     \
/       \
---------
|       |
|  ---  |
|  | |  |
|  ---  |
|       |
---------


And you're done! This is a 1x1 house. a 2x2 house would look like this:

        *
/ \
/   \
/     \
/       \

|  ---  |  ---  |
|  | |  |  | |  |
|  ---  |  ---  |
|       |       |
-----------------


and a 3x2 house:

            *

# The challenge

You must write a full program that takes two integers, x and y, and prints a house that is X rooms wide and Y rooms tall. Your program should be able to handle houses up to 10x10. IO can be in any reasonable format. Trailing spaces on each line are allowed, and one trailing newline is allowed.

Try it online!

I've improved my vim-golfing skills significantly since I posted this answer, so I decided to go back and write this whole thing from scratch. Saved thirty-three bytes in the process!

Input is assumed to be on two separate lines, so that the buffer looks like this before you start typing:

3
4


I had a very detailed explanation, but I don't feel like writing it all over again from the beginning... >_< Check out the revision history if you still want to see it.

## Python 3.6 (pre-release), 221210 203 bytes

Reads 2 integers (separated by comma) from stdin, prints the house to stdout.

x, y = eval(input())
w = 8 * x + 1 # total width (in characters)
p = '-' * w + '\n' # floors

Mar 3, 2016 at 10:32 • @Sp3000 That does work, thanks. I guess \- doesn't mean anything as an escape sequence, so the \- is just parsed as 2 characters. Then of course - has a special meaning to tr, so we need the string ' \-' for the windows to escape the - (mapping C-> space, B->- and A->- as there are no more characters left.) For the floors, we have only the string '-' and in this case tr seems happy to interpret it just as a literal rather than a special character, assigning C=B=A = '-' All in all it was a tricky thing to get working. I'm sure there's more golfing to do, will edit later.

You can also save a byte by reusing assigned empty strings (once m is assigned, you can assign o=m saving the "". Replace also takes strings, so you can use your q instead of ' ', and there is no need for the space after the > when declaring r.

Invoke for best effect in the Immediate window of the VBA editor: ?H(8,8) for example. ?H(8,8) * / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ ----------------------------------------------------------------- | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | | | | | | | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | ----------------------------------------------------------------- | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | | | | | | | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | ----------------------------------------------------------------- | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | | | | | | | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | ----------------------------------------------------------------- | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | | | | | | | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | ----------------------------------------------------------------- | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | | | | | | | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | ----------------------------------------------------------------- | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | | | | | | | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | ----------------------------------------------------------------- | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | | | | | | | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | ----------------------------------------------------------------- | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | | | | | | | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | | | | | | | | | -----------------------------------------------------------------  # APL (Dyalog Extended), 91 bytes '*'↑⍨-1+3×w←⎕ ' /'[⊖a],' ',' \'[a←∘.=⍨⍳w×3] ' |-'[2⍪⍨2⍪¯1↓⊃⍪/⎕⌿⊂1,⍨⊃,/w/⊂⍉3⊤269+⎕AV⍳'4 4#']  Try it online!
