[](https://hub.docker.com/repository/docker/egortensin/math-client/builds)
[](https://travis-ci.com/egor-tensin/math-server)
[](https://ci.appveyor.com/project/egor-tensin/math-server/branch/master)
Development
-----------
Build using CMake.
Depends on Boost.{Asio,Filesystem,Program_options,Test}.
Usage
-----
### `server`
If you just run `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
Consult `server --help` for more info.
### `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,
> client -c "2 * 2"
4
* a file(s),
> client test.txt
result1
result2
* stdin.
> client
1

2 * 2
4
1 / (3 - -3)
0.16666666666666666
1 / (-3 - -3)
server error: parser error: division by zero
Consult `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
