# Voerbak
Here's the source for voerbak, this project's connect 4 engine. The name comes from an abbreviation for the Dutch word for connect 4: Vier Op Een Rij -> VOER + bak = voerbak
Voerbak uses a 1-dimensional array for storing the playfield, and it's printed after every move. The ordering is left to right, then bottom to top:
35|36|37|38|39|40|41
-|-|-|-|-|-|-
28|29|30|31|32|33|34
21|22|23|24|25|26|27
14|15|16|17|18|19|20
7|8|9|10|11|12|13
0|1|2|3|4|5|6
Voerbak is used in this project using api/game/voerbak_connector.py
## Building
```sh
make
```
## Input
Voerbak takes moves seperated by newlines from stdin. An example game would look like this:
``` sh
echo "4,3,3,2,1,2,2,7,1,7,1,7,1" | sed "s/,/\n/g" | ./voerbak
# ^ convert "," to newline
```
## Output
Voerbak outputs special messages in this format:
```
e:full
^ \__/
| |
| message (without spaces)
|
message type
```
Message reference:
type|name|messages
-|-|-
d|draw|full = board is full
e|errors|full = column is full
m|move|true|false = if it's player 1's move
w|win|int-int = board indices where 4 was connected
## Command-line arguments
```sh
$ ./voerbak --help
