SwiftChatSE

A Swift library for Stack Exchange chat

SwiftChatSE is a library made from FireAlarm-Swift's chat code. It works on macOS and Linux.

Example

Here are instructions to build a simple program which posts "Hello, world!" in SOBotics.

Installing libwebsockets

brew and apt-get provide different versions of libwebsockets, and both are outdated, so you'll have to install it from source. Make sure you have OpenSSL and CMake installed, and run the following commands to download and install libwebsockets from here:

git clone https://github.com/warmcat/libwebsockets.git
cd libwebsockets
mkdir build
cd build
export OPENSSL_ROOT_DIR=$(brew --prefix openssl)
cmake ..
make
sudo  make install

Writing and building the program

Create a Swift Package Manager project:

mkdir ChatTest
cd ChatTest
swift package init --type executable

Modify Package.swift:

import PackageDescription

let package = Package(
    name: "ChatTest",
    dependencies: [
        .Package(url: "git://github.com/SOBotics/SwiftChatSE", majorVersion: 4)
    ]
)

Now write the code, in Sources/main.swift:

import SwiftChatSE

let email = "<email>"
let password = "<password>"

//Create a Client and log in to Stack Overflow.
let client = Client(host: .StackOverflow)
try! client.login(email: email, password: password)

//Join a chat room.
let room = ChatRoom(client: client, roomID: 111347)	//SOBotics
try! room.join()

//Post a message.
room.postMessage("Hello, world!")


room.leave()

You'll have to run the following command to build:

swift build -Xswiftc -lwebsockets -Xswiftc -I/usr/local/opt/openssl/include -Xswiftc -I/usr/local/include -Xlinker -lwebsockets -Xlinker -L/usr/local/lib

After running the swift build command, the executable will be placed in the directory .build. If you want to use Xcode to develop, just copy swiftchatse.xcconfig to your project directory and run:

swift package generate-xcodeproj --xcconfig-overrides swiftchatse.xcconfig

to generate an Xcode project. You'll have to recreate the project if you add files or change package settings.
