They're all a little dumb. I asked claude for a python function or functions that will take in markdown in a string and return a string with ansi codes for bold, italics and underline. It gave me a 160 line parse function. After gaping for a short while, I implemented it in a 5 line function and a lookup table. These vibe codes who are proud that they generated thousands of lines of code makes me wonder if they are e…

I just asked Gemini Flash to do this. I included the instruction to use regular expressions to do the conversion to ANSI. It gave me a reasonable Python function which boils down to calling `re.sub()` for each of bold, italic and underline. For italics: text = re.sub(r'(\*|_)(.+?)\1', replace_italic, text, flags=re.DOTALL) The `replace_italic` is a one line callback function surrounding the re's match with the ANSI c…

  import re
  
  def markdown_to_ansi(markdown_string: str) -> str:
      ansi_string = markdown_string

      ANSI_BOLD = "\033[1m"
      ANSI_ITALIC = "\033[3m"
      ANSI_UNDERLINE = "\033[4m"
      ANSI_RESET = "\033[0m"
  
      ansi_string = re.sub(r'\*\*(.*?)\*\*', f'{ANSI_BOLD}\\1{ANSI_RESET}', ansi_string)
      ansi_string = re.sub(r'__(.*?)__', f'{ANSI_BOLD}\\1{ANSI_RESET}', ansi_string)
  
      ansi_string = re.sub(r'\*(.*?)\*', f'{ANSI_ITALIC}\\1{ANSI_RESET}', ansi_string)
      ansi_string = re.sub(r'\_(.*?)\_', f'{ANSI_ITALIC}\\1{ANSI_RESET}', ansi_string)
  
      ansi_string = re.sub(r'\+\+(.*?)\+\+', f'{ANSI_UNDERLINE}\\1{ANSI_RESET}', ansi_string)
  
      # A more robust solution for nesting would require a parsing library or a more complex state machine.
      # However, for simple cases, applying in order can layer them correctly.
  
      return ansi_string

Back before structured outputs were common among model providers, I used to have a “end result” tool the model could call to get the structured response I was looking for. It worked very reliably. It’s a bit of a hack but maybe that reliably works here?

You can definitely build an agent and have it use tools like you mention. That’s the equivalent of making 2 requests to Gemini, one to get the initial answer/content, then another to get it formatted as proper json The issue here is that Gemini has support for some internal tools (like search and web scraping), and when you ask the model to use those, you can’t also ask it to use application/json as the output (which…

Can't agree with that. Gemini doesn't lead just on price/performance - ironically it's the best "normie" model most of the time, despite it's lack of popularity with them until very recent. It's bad at agentic stuff, especially coding. Incomparably so compared to Claude and now GPT-5. But if it's just about asking it random stuff, and especially going on for very long in the same conversation - which non-tech users h…

My pet theory without any strong foundation is because OpenAI and Anthropic have trained their models really hard to fit the sycophantic mold of: =============================== Got it — *compliment on the info you've shared*, *informal summary of task*. *Another compliment*, but *downside of question*. ---------- (relevant emoji) Bla bla bla 1. Aspect 1 2. Aspect 2 ---------- *Actual answer* ----------- (checkmark e…

I just wish the Gemini app would stop inserting and auto playing a YouTube video into nearly every response when I'm on a mobile connection. There appears to be no way to stop it.
