import tkinter as tk
from tkinter import messagebox, ttk
import webbrowser
import feedparser

RSS_URL = "https://blog.python.org/feeds/posts/default"

article_links = []


def clean_text(text):
    """Converts text to basic ASCII to strip non-supported Android Tkinter characters."""
    if not text:
        return ""
    # Encodes to ASCII ignoring emojis, special quotes, and unsupported byte sequences
    clean = text.encode("ascii", "ignore").decode("ascii")
    # Removes extra whitespace and linebreaks
    return " ".join(clean.split())


def load_feed():
    global article_links

    listbox.delete(0, tk.END)
    article_links.clear()

    status_label.config(text="Fetching articles...", foreground="blue")
    root.update()

    try:
        feed = feedparser.parse(RSS_URL)

        if not feed.entries:
            status_label.config(text="No articles found.", foreground="red")
            return

        for entry in feed.entries:
            title_raw = entry.get("title", "Untitled")
            title = clean_text(title_raw)
            link = entry.get("link", "")

            listbox.insert(tk.END, title)
            article_links.append(link)

        status_label.config(
            text=f"Loaded {len(feed.entries)} articles!", foreground="green"
        )

    except Exception as e:
        status_label.config(text="Connection error!", foreground="red")
        messagebox.showerror("Error", f"Failed to load feed:\n{e}")


def open_link(event):
    try:
        index = listbox.curselection()[0]
        url = article_links[index]
        if url:
