Building a ChatGPT Replica with Fyne in Go
In this step-by-step guide, we will create a simple ChatGPT replica using the Fyne framework in Go. The application will have a graphical user interface (GUI) that allows users to input messages and receive responses from ChatGPT.
Prerequisites
Before we begin, ensure you have the following installed:
- Go programming language
- Fyne framework (
go get fyne.io/fyne/v2) - The
ollamaandlangchaingopackages for language model integration (go get github.com/tmc/langchaingo/llms,go get github.com/tmc/langchaingo/llms/ollama)
Step-by-Step Guide
Step 1: Initialize the Application
First, let’s initialize our Fyne application and create a new window.
Step 2: Create the RichText Widget for Conversation
We need a RichText widget to display the conversation between the user and ChatGPT.
Step 3: Create the Entry Widget for User Input
We also need an Entry widget where the user can type their messages.
Step 4: Define the sendMessage Function
The sendMessage function captures the user's message, updates the conversation, and calls the function to get the ChatGPT response.
Step 5: Create the Send Button and Set Up the Enter Key Event
We create a button to send the message and set up the Enter key event to trigger the sendMessage function.
Step 6: Organize Widgets in the Layout
We use containers to organize the widgets in the layout.
Step 7: Adjust the Window Size Dynamically
We adjust the window size based on the screen size and set up a dynamic width adjustment for the Enter key.
Step 8: Create the Response Function
We define the createResponse function to generate the ChatGPT response and update the conversation.
Conclusion
By following these steps, you have created a simple ChatGPT replica using the Fyne framework in Go. The application captures user input, sends it to ChatGPT, and displays the response in a RichText widget. This guide provides a basic framework that you can expand upon to create more sophisticated chat applications.
