-- | A game engine library for tactical squad ASCII roguelike dungeon crawlers
--
-- LambdaHack is a Haskell game engine library for ASCII roguelike games
-- of arbitrary theme, size and complexity, with optional tactical squad
-- combat. It's packaged together with a sample dungeon crawler in a
-- quirky fantasy setting. The sample game can be tried out in the
-- browser at http://lambdahack.github.io.
--
-- Please see the changelog file for recent improvements and the issue
-- tracker for short-term plans. Long term goals include multiplayer
-- tactical squad combat, in-game content creation, auto-balancing and
-- persistent content modification based on player behaviour.
-- Contributions are welcome.
--
-- Other games known to use the LambdaHack library:
--
--
--
-- Note: All modules in this library are kept visible, to let games
-- override and reuse them. OTOH, to reflect that some modules are
-- implementation details relative to others, the source code adheres to
-- the following convention. If a module has the same name as a
-- directory, the module is the exclusive interface to the directory. No
-- references to the modules in the directory are allowed except from the
-- interface module. This policy is only binding when developing the
-- library --- library users are free to access any modules, since the
-- library authors are in no position to guess their particular needs.
--
-- This is a workaround .cabal file, flattened to eliminate internal
-- libraries until generating haddocks for them is fixed. The original
-- .cabal file is stored in the github repo.

-- Why do both readsPrec and readPrec exist, and why does

--
-- readPrec, on the other hand, is based on a much more efficient

-- recommended to use readPrec instead of readsPrec
-- whenever possible for the efficiency improvements it brings.
--
-- As mentioned above, derived Read instances in GHC will

-- Derived instances of Show have the following properties, which
-- are compatible with derived instances of Read:
--
--
-- - The result of show is a syntactically correct Haskell
-- expression containing only constants, given the fixity declarations in
-- force at the point where the type is declared. It contains only the
-- constructor names defined in the data type, parentheses, and spaces.
-- When labelled constructor fields are used, braces, commas, field
-- names, and equal signs are also used.
-- - If the constructor is defined to be an infix operator, then
-- showsPrec will produce infix applications of the
-- constructor.
-- - the representation will be enclosed in parentheses if the
-- precedence of the top-level constructor in x is less than
-- d (associativity is ignored). Thus, if d is
-- 0 then the result is never surrounded in parentheses; if
-- d is 11 it is always surrounded in parentheses,
-- unless it is an atomic expression.
-- - If the constructor is defined using record syntax, then
-- show will produce the record-syntax form, with the fields given
-- in the same order as the original declaration.
--
--
-- For example, given the declarations
--
--
-- infixr 5 :^:

-- | UI screen coordinates, independent of whether square or monospace
-- fonts are being placed on the screen (though square fonts are never
-- placed on odd coordinates). These are not game map coordinates, becuse

data PointUI

-- | Coordinates of the big square fonts. These are not game map

-- However, confusingly, Point is also used for square font

-- be sent to a frontend, namely PointArray.Array, which is

module Game.LambdaHack.Client.UI.Overlay
-- | Three types of fonts used in the UI. Overlays (layers, more or less)
-- in proportional font are overwritten by layers in square font, which
-- are overwritten by layers in mono font. All overlays overwrite the
-- rendering of the game map, which is the underlying basic UI frame,
-- comprised of square font glyps.
--
-- This type needs to be kept abstract to ensure that frontend-enforced
-- or user config-enforced font assignments in FontSetup (e.g.,
-- stating that the supposedly proportional font is overriden to be the
-- square font) can't be ignored. Otherwise a programmer could use
-- arbirary DisplayFont, instead of the one taken from
-- FontSetup, and so, e.g., calculating the width of an overlay so
-- constructed in order to decide where another overlay can start would
-- be inconsistent what what font is really eventually used when
-- rendering.
--
-- Note that the order of constructors has limited effect, but it
-- illustrates how overwriting is explicitly implemented in frontends
-- that support all fonts.

-- | The common, for server and clients, main game state type and its
-- operations.
module Game.LambdaHack.Common.State
-- | The main game state, the basic one, pertaining to a single game, not
-- to a single playing session or an intersection of both. This state
-- persists between playing sessions, until the particular game ends.
-- Anything that persists between games is stored in server state, client
-- state or client UI session state.
--
-- Another differentiating property of this state is that it's kept
-- separately on the server and each of the clients (players, human or
-- AI) and separately updated, according to what each player can observe.
-- It's never updated directly, but always through atomic commands
-- (CmdAtomic) that are filtered and interpreted differently on
-- server and on each client. Therefore, the type is a view on the game
-- state, not the real game state, except on the server that alone stores
-- the full game information.

--
-- If the level has inaccessible open areas (at least from the stairs AI

-- be placed on open or small levels, or in dispersed enough that they

-- yt = d
-- (yt - y) (xf - x) = (xt - x) (yf - y)

--
-- 45678
-- 123
-- @
--
--
-- so the first processed diamond is at (-1, 1). The order is similar as
-- for the restrictive shadow casting algorithm and reversed wrt PFOV.
-- The fast moving line when scanning is called the shallow line, and
-- it's the one that delimits the view from the left, while the steep
-- line is on the right, opposite to PFOV. We start scanning from the
-- left.
--
-- The PointI (Enum representation of Point)
-- coordinates are cartesian. The Bump coordinates are cartesian,
