Question is: How can I escape this return result and maintain formatting using printft()?
So, I've included the code below since it shows the dilemma better, but what I have is a very terrible little youtube searcher + mpv player that actually handles playlist searching unlike every single other popular library right now. When I get the results return, I use print_formatted_text(HTML) to display it all with basic coloring and such. Without proper escaping, I get this error occasionally:
not well formed (invalid token): line 1, column 111
when the return includes some damn character that gets spit back by the function. If I use printft(HTML(escape ... and escape my entire f-string, I lose formatting or color or whatever else I wanna do with it since, well, it's all escaped. I cannot do something like
printft(HTML ...)) + print(escape [results])) because of the + operator and comparing int and str, plus it feels like the worst possible solution to this anyway. I've included the len section of my search to demonstrate why I can't do an int and why I might just be a bigass dummy here and missing something obvious. Also, I feel like I have to use len for the comparison because the API has a limit and Google says I am going to burn in hellfire if I exceed it.
for i, result in enumerate(results, start=1):
if 'title' not in result:
print_formatted_text(HTML("No results found"), style=style)
continue
i = 0 + i
print_formatted_text(HTML(f"{i}. Title: <title>{result['title']}</title>"), style=style)
if search_type == 'v':
if 'videoId' not in result:
print_formatted_text(HTML("No results found"), style=style)
continue
print_formatted_text(HTML(f" Video ID: <video-id>{result['videoId']}</video-id>"), style=style)
if 'description' not in result:
print_formatted_text(HTML("No description found"), style=style)
continue
print_formatted_text(HTML(f" <descriptiontext>Description: {(result['description'][:100])}...</descriptiontext>"), style=style)
else:
if 'playlistId' not in result:
print_formatted_text(HTML("No results found"), style=style)
continue
print_formatted_text(HTML(f" <video-id>Playlist ID:</video-id> {result['playlistId']}"), style=style)
if 'description' not in result:
print_formatted_text(HTML("No description found"), style=style)
continue
print(f" Description: {(result['description'][:100])}...")
print_formatted_text("━" * 50)

The Problem: Escape Issue: You want to escape the HTML content to avoid issues with invalid tokens (such as unescaped special characters), but you lose the formatting (like colors) when using escape(). HTML Content: You are using HTML() for styling (e.g., coloring text), and applying escape() would interfere with that. Solution: Instead of escaping the entire HTML string, you can sanitize the content only where necessary, keeping the formatting intact. You should:
Only escape the parts of the HTML that could cause issues, such as dynamic content (like description). Use the HTML() formatter correctly to prevent your formatted string from being malformed.
