A Swift library for Stack Exchange chat
SwiftChatSE is a library made from FireAlarm-Swift's chat code. It works on macOS and Linux.
Here are instructions to build a simple program which posts "Hello, world!" in SOBotics.
brew and apt-get provide different versions of libwebsockets, and both are outdated, so you'll have to install it from source.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
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.
