Inspired by the Brogue cellophane idea/stitching template idea.


Basic idea and explanation

The basic idea is that you will be given a sample/entire room such as


#######
#.....#
#.....*
#.....#
#.....#
#....>#
#######

The room is 7x7 there are various symbols in the room.

From here we would slice too room into various chunks of YxY (could do different dimensions but why not is discussed later) that exhaust all possible placement of the YxY square

So this 7x7 room sliced into 5x5 (for simplicity sake in showing this by hand) items would be.

1

#####
#....
#....
#....
#....

2

#####
.....

9

....#
....*
....#
...>#
#####

Store a tokenized version of the slices as a key in a hash pointing to a list of top left (or your corner of choice) points as multiple slices may be the same token (3x3 slices of the given room will produce a lot of ......... tokens).

Now reference templates

A reference template is an update to a room based on existing geometry. IE a 5x5 template to create a "pillar" in the corner room would be as follows.

reference

??#??	
?...?
#...?
?...?
?????

result

??#??
?...?
#.#.?
?...?
?????

The ? marks do not care what the tile in that relative location is but other items must match. The result will blit in all items except for ? marks. to best fill the items this object will be rotated 3 times so that all cases will be caught without having to make 4 variations on this design.

Create a token of all references and using regex or your choice of string comparing get a list of the tokens created by the room as per one of the points in the list.

From here you can randomly choose an item to apply the result to or possibly apply the result to all items in the room (which might be silly but work for your purpose). In this example the following would be selected from the room.

1

#####
#....
#....
#....
#....

7

#....
#....
#....
#....
#####


So the room could end with the result of

#######
#.....#
#.#...*
#.....#
#.....#
#....>#
#######

or

#######
#.....#
#.....*
#.....#
#.#...#
#....>#
#######

if we only pick one

If all are done (without caring about overlap)

#######
#.....#
#.#...*
#.....#
#.#...#
#....>#
#######

This idea could be used for putting in items, monsters or other such

So what about odd sized rooms?

a 2*3 reference would look like this

?##
?>#
?.#

Due to how things are read it doesn't matter what the ??? is. This said it will not read past the edge of the room to allow the template to fit.

it requires a bit more work with odder items such as 2*4 but this could be automated.

??##
??>#
??.#
??.#
?##?
?>#?
?.#?
?.#?
?##?
?#>?
?#.?
?#.?
##??
>#??
.#??
.#??

A bit of mirroring could save time, just check to see if the tokenized version exists.

A bonus is that entire dungeons can be made if a background "Unfilled" symbol is used.

Start with grid of unfilled

create a starting template and replace string to represent starting room.

blit it to a proper location (realistically anywhere on the grid will happen)

XXXXXXXXXX
XXXXXXXXXX

Create new rooms with a template searching for doors (or empty floor squares to create expansive rooms)

Note the template cares about a door surrounded by walls, followed by a chunk of 6 "unfilled" tiles. The unfilled tiles are the footprint of the room that will be blitted in. The only real thing that the template should care about is the door and/or wall that it is expanding upon and the room footprint that it is filling in. This allows it to snugly fit against other rooms or expand out into the unfilled area.

Let it run for how many rooms you want or until you can't place anything more

Large example

The following map was created with the following templates

First room was created with following template placed on a 15x15 square of x tiles

XXXXXXXXXXXXXXX
X######+######X
X#...........#X
X#...........#X
X#...........#X
X#...........#X
X#...........#X
X+...........+X
X#...........#X
X#...........#X
X#...........#X
X#...........#X
X#...........#X
X######+######X
XXXXXXXXXXXXXXX

Next 20 iterations of rooms were attempted to be placed.

The template string was

?????##+##?????
?XXXXXXXXXXXXX?
?XXXXXXXXXXXXX?
?XXXXXXXXXXXXX?
?XXXXXXXXXXXXX?
?XXXXXXXXXXXXX?
?XXXXXXXXXXXXX?
?XXXXXXXXXXXXX?
?XXXXXXXXXXXXX?
?XXXXXXXXXXXXX?
?XXXXXXXXXXXXX?
?XXXXXXXXXXXXX?
?XXXXXXXXXXXXX?
???????????????

The replacement string was the following. Only 1 was choosen to create rooms of the same exact size on the same grid patern

???????????????
?######+######?
?#...........#?
?#...........#?
?#...........#?
?#...........#?
?#...........#?
?+...........+?
?#...........#?
?#...........#?
?#...........#?
?#...........#?
?#...........#?
?######+######?
???????????????

Corner themes had the following template

???????
?######
?#.....
?#.....
?#.....
?#.....
?#.....

The following strings were used for replacement

???????
???????
??.....
??.##..
??.##..

And some middle pillars/pit/other such things

The template for this

???????
?.....?
?.....?
?.....?
?.....?
?.....?
???????

and the replacement string

???????
?.....?
?.###.?
?.###.?
?.###.?
?.....?

?.___.?

Resulting map after empty doors were removed or turned to floor tiles. Not the most exciting result but this is still experimental. More runs of the corner and pillar/pit in middle of room would make this more interesting.
