math-server

Development

Build using CMake. Depends on Boost.{Filesystem,Program_options,Regex,Test}.

There's a Makefile with useful shortcuts to build the project in the build/ directory along with the dependencies:

make deps
make build
make test

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
144
