Usage
-----
### `math-server`
If you just run `math-server`, it'll start a server on port 18000.
You can `telnet` to it, type in arithmetic expressions, and it'll give you the
results:
1
1
2 * 2
4
1 / (3 - -3)
0.16666666666666666
1 / (-3 - -3)
server error: parser error: division by zero
-4 ^ 2
-16
(-4) ^ 2
16
Consult `math-server --help` for more info.
### `math-client`
A `telnet`-like client for the server.
It'll try to connect to the server on localhost:18000.
Supports reading input from:
* the command line,
> math-client -c "2 * 2"
4
* a file(s),
> math-client test.txt
result1
result2
* stdin.
> math-client

Consult `math-client --help` for more info.
### Docker
Start the server using
docker-compose pull && docker-compose up -d server
Connect to localhost:18000 to query it or run the client:
> docker-compose run --rm client -c "69 * 420"
28980
> docker-compose run --rm client
12 * 12
