cd nng
mkdir build
cd build
cmake .. -DBUILD_SHARED_LIBS=True
make && sudo make install
The easiest way to download lua-nng is with [luarocks](https://github.com/luarocks/luarocks).
You can also clone this repository and build locally
git clone https://cogarr.net/source/cgit.cgi/lua-nng
cd lua-nng
sudo luarocks build
```
luarocks install --server=http://rocks.cogarr.net lua-nng
```
## Example
local nng = require("nng")
local s1 = nng.pair1_open()
local s2 = nng.pair1_open()
s1:listen("ipc:///tmp/pair.ipc")
s2:dial("ipc:///tmp/pair.ipc")
s2:send("hello")
print(s1:recv()) --prints "hello"
