Add a dungeon level generator, which:
1. generates an infinite sequence of rectangular rooms within the
dimensions of the level
2. removes any duplicates from that sequence
3. Generates a graph from the delaunay triangulation of the centerpoints
of those rooms
4. Generates the minimum-spanning-tree of that delaunay triangulation,
with weights given by line length in points
5. Adds back a subset (default 10-15%) of edges from the delaunay
triangulation to the graph
6. Uses the resulting graph to draw corridors between the rooms, using a
random point on the near edge of each room to pick the points of the
corridors

Implement ToJSON and FromJSON for all of the various pieces of the game
state, and add a pair of functions saveGame/loadGame implementing a
prism to save the game as zlib-compressed JSON. To test this, there's
now Arbitrary, CoArbitrary, and Function instances for all the parts of
the game state - to get around circular imports with the concrete
entities this unfortunately is happening via orphan instances, plus an
hs-boot file to break a circular import that was just a little too hard
to remove by moving things around. Ugh.

Allow specifying the seed for the game's global RNG on startup, and
print the seed when the game exits. This'll allow us to more reliably
reproduce bugs - yay!

Add a new "Item" entity, which pulls from the previously-existent
ItemType raw, and add a "PickUp" command which takes the (currently
*only*) item off the ground and puts it into the inventory.

Randomly select a position in the largest contiguous region of the
generated level in which to place the character at startup time.
|
|
Add support for converting generated levels to walls, and merge one into
the entity map at the beginning of the game.
There's nothing here that guarantees the character ends up *inside* the
level though (they almost always don't) so that'll have to be slotted
into the level generation process.

Add a cellular-automata-based cave level generator, plus an
optparse-applicative-based CLI for invoking level generators in general.
|
|
Add a "say" function for saying messages within an app monad to the
user, and link everything up to display them and track their history
|
|
Add support for entities via a port of the EntityMap type, and implement
command support starting at basic hjkl.

Initial commit of a Haskell version of Xanthous, written using Brick and
built with Nix.
This is so much nicer and so much easier
