# AnnaConnect

AnnaConnect is a silly little text-based connect 4 game c:

Supports vt100 escape codes and ncurses for drawing the UI.
There is also an option to let the game (randomly) play itself for testing,
which does not need a UI.

# Header files

## `types.h`
The `types.h` file defines the types used in all of the program.

### Integer types
- `rowsint_t`: row numbers.
- `columnsint_t`: columns numbers.
- `winint_t`: amount of wins.
- `column_t`: the bit field of the pieces in a column, LSB is the bottom of the board.

### Structs

#### `wincount_t`
This struct has all counts for all the wins made my a players.
- `winint_t total`: total amount of wins
- `winint_t horizontal`: amount of wins from a horizontal line
- `winint_t vertical`: amount of wins from a vertical line
- `winint_t diagonalUp`: amount of wins from a line going diagonally up (from left to right)
- `winint_t diagonalDown`: amount of wins from a line going diagonally down (from left to right)

#### `board_t`
This struct has an enire board.
- `bool player`: The current player
- `rowsint_t *height`: An array with the amount of pieces in each column
- `column_t *column`: An array of all the columns in the board
- `rowsint_t rows`: The amount of rows the baord has
- `columnint_t columns`: The amount of columns the board has
- `wincount_t count0`: A struct holding the counts of wins player 0 has gotten
- `wincount_t count1`: A struct holding the counts of wins player 1 has gotten

## `ui.h`
The `ui.h` file describes the functions each `ui_*.c` user interface is expected to implement.
These should be ass cross-platform as possible for the used backend.
So for example the ui_vt100.c supports all platforms where vt100 escape codes are supported.

When implementing a new ui, you can start from `ui_stub.c`.
This "ui" is just the bare minimum to let the rest of the code work.

## `commandline.h`
The `commandline.h` file has the function that handles command-line argument parsing.

## `logic.h`
The `logic.h` file has the types used in `logic.c` and the functions it exposes.

## `macros.h`
The `macros.h` file has macros for simple stuff.

## `config.h`
The `config.h` defines default board size, and wether or not the displayed row and column numbers start at 0.
