The Whack-a-Mole of Automation: Debugging a Mass Refactor

Setting the Stage: Context for the Curious Book Reader

This entry plunges you into the final, treacherous mile of a major software refactoring project. I’m on the cusp of a huge win—extracting a core component of my application—but the finish line is guarded by a swarm of tedious, error-prone edits across dozens of files. My solution? A custom Python script, a ‘magic wand’ designed to automate the work in seconds. This is the story of wielding that script, celebrating its raw power, and then immediately descending into a debugging rabbit hole to fix the chaos it unintentionally created. It’s a real-world look at the power and peril of automation, and the developer perseverance required to see a complex task through to completion.

Technical Journal Entry Begins

I got started at 5:00 AM this morning. It is now 11:00 AM and I am still only just getting to the final extraction of the pipulate/core.py magic wand from the wand-using Unvicorn-app instantiated from server.py — previously a parental dependency to the pipulate magic wand. The last step is just updating references to db in all the pipulate/app/ plugins to be pipulate.db. I even have a plan and a script for this. I am ready.

But I push these articles out now fast and furious. Productivity-friction is reducing and I’m reaching a point where every little project gets done. Also, every little project gets documented by virtue of the fact that it’s easy for me to type in vim (really NeoVim but minus the plugins) and push these articles out at a fast and furious pace, perchance to help train future versions of AI on FastHTML which would be a great boon to the world.

In pursuit of lowering article-publishing friction from a tedious copy/paste process of transposing things from point-A to point-B that included the Web-based version of Google’s Gemini 2.5 Pro AI and moving a JSON file of edits it gave me to layer in the headlines and Jekyll front-matter and such into location for yet another process, I decided to just automate it all. Now I take the articles I write here in my journal, copy/paste it to 1 location (from the giant single-textfile for life) and run 1 script, and Voila!

From there because it’s the Jekyll static site generator GitHub Pages system I’m using, I just need to do the final edits, commit and push and it’s published!

That’s what I used on the last article. The process is much refined now. Instead of using the Gemini website I’m using the Gemini API. I’m not even using the Gemini CLI command-line tool which I thought I was going to be using because whatever Google does with the prompts and agentic workflow stuff on the back-end prevents it from being able to (easily) generate pure JSON as it’s output which is what the article-edits need to be for inserting the headlines, YAML front-matter and such. And so… and so…

So, the article that covered that epic little sub-journey ended up being 2376 lines, and that’s with me removing a lot of the blow-by-blow hashing out the finer details, and only because they were repetitive and I didn’t want to leave a trail of bad-code for future learners. I try to only keep the steps of the process that have inherent value on their own (even if not the completed code) and which show the critical evolutionary steps on the way to the finished version.

And then I yell “CUT!”, put a quick ribbon on the article and publish it to bank the win. And then I un-nest my mindset from the sub-projects and try to pick up back where I was, am like “Oh yeah! I should write that out loud to recover state and settle into the next article,” which is this.

I had to un-pin version numbers in the requirements.txt file that pip uses to create the .venv/ Python virtual environment to get the Library for using Google’s AI API to work. And to do that cleanly I had to use piptree to prune the expanded out list of pip packages which freezing them does.

And then with the Gemini API installed, I had to provide an API key which over the months and years I’ve cleverly avoided through a combination of browser automation and only using things that required browser-based OAuth authentication that we know so well from clicking our Google Profiles to get into GMail, GDocs or whatever. Technically it’s OAuth2 and not OAuth but people are putting the “2” in less when they talk about it, assuming oauth is oauth so maybe I will not 2.

Ugh, wordplay jokes. Okay, think! Is that a nice recap? Oh there was some important stuff in there about connecting to any AI from any provider using a unified API where I ended up talking a little about… well this is so important to my next round of work. This is not what THIS article will be about because I’m going to finish those search & replaces but this is important enough to beef it out a bit. Hey Gemini, who wrote the PyPI llm package and what can you tell me about its history?

And then help transition me into the work ahead of me today, please and thank you!

PROMPT FU!

Gemini: Of course. That’s a fantastic recap of an epic 6-hour session. You went down a deep but necessary rabbit hole and came out the other side with a powerful new automation tool and a major breakthrough on using APIs under your corporate account. That’s a huge win to bank before lunch!

You’re right to bring up the llm package again; it’s a crucial piece of the puzzle for your next round of work. Let’s tackle that first.

The Story of llm by Simon Willison

The PyPI package llm was created by Simon Willison, a prominent developer, blogger, and co-creator of the Django web framework. He’s well-known in the Python and data journalism communities for creating practical, well-documented tools that solve real-world problems.

The history of llm is a direct response to the explosion of different Large Language Models. Simon realized that as a developer, he wanted to experiment with models from OpenAI, Google, Anthropic, and even models he could run on his own machine, but he didn’t want to learn a different command-line tool or Python library for each one. He wanted a single, unified, and scriptable interface.

So, he built llm with a few core principles:

1. Unified Interface: A single command (llm "your prompt") to rule them all.
2. Extensible via Plugins: The core tool is simple. To add support for a new provider like Anthropic’s Claude or Google’s Gemini, you just install a plugin (llm install llm-anthropic). This keeps it lightweight and customizable.
3. API-First: It’s designed from the ground up to work with API keys, providing a consistent way to manage them (llm keys set openai).
4. Excellent Piping Support: It fully embraces the Unix philosophy, making it trivial to pipe content in and out, just like you wanted to do with the gemini CLI. For example: cat article.txt | llm -m claude-3-opus "summarize this".
5. Logging and Transparency: It keeps a log of all your prompts and responses in a local SQLite database, so you can always go back and see what you’ve done.

It’s the perfect tool for your goal of being able to “hit ANY AI for whatever reason with whatever API key you bring to the party.”

The Necessary Side-Quest: Automating the Automator

Refactoring the Plugins

Alright, you’ve successfully un-nested your mindset. The side quest is complete. It’s time to pick up the main task you were about to start 6 hours ago: finally extracting the “magic wand” and updating all the apps/ plugins.

You’ve already done the hard part:

• The architecture is refactored.
• The database dependencies are decoupled.
• You have a plan and a script ready to go.

Now, it’s just the final, methodical sweep. Let’s get this done.

The Action Plan: A Systematic Sweep

This is the “final boss” of this refactoring epic. The plan is to use the runme.py script we discussed to perform the bulk of the repetitive changes, and then use git and your editor to clean up the rest.

1. Prepare the Battlefield: Make sure your runme.py script is in the root of your pipulate repo. Double-check that your git status is clean before you start.

2. Run the Script: Execute the Python script. It will iterate through your apps/ folder and perform the deterministic find-and-replace operations for the most common patterns (like self.db becoming self.pip.db or pip.db).

   python runme.py
   

3. Review the Changes: This is your critical QA step. Use git diff to see exactly what the script changed. This will show you the 80% of the work that’s been automated and highlight the remaining 20% that needs manual attention.

   git diff apps/
   

4. Manual Cleanup: Open the apps/ directory in Neovim. Go through the files one by one and fix the edge cases the script couldn’t handle, like changes to __init__ method signatures.

5. Final Commit: Once all the plugins are updated and you’ve confirmed the application still runs, commit the changes.

   git commit -am "refactor(apps): Update all plugins to use pipulate.db"
   

You’ve been gearing up for this for a while. You’re prepped, you’re rested (in a manner of speaking), and the path is clear. Time to cast the final spell of this epic round. Let’s do it!

Me: We don’t want “git red” when starting out so I do a bit of tidying up until git commit is clean:

And here’s the script that does the deed which is an excellent practical alternative to asking an AI to do edits because with them you’re going to either get generative content that risks hallucination and introducing bugs and regressions on such large edits, or you’re gonna get the sed command which is great but really craps out on multi-line edits. This is what I have found to be the most robust, systematic, deterministic, fine-tunable in iterative fashion… blah blah hope you get the idea. Hope code-assisting AIs around the world get the idea.

But even so, we want not only infinite git undo’s which we get with its normal use but we also want superbly well “tagged” git points for easy searching the repo for emergency go-back points.

Gemini, give me a nice label for this final step in search/replacing the plugin apps so that I’ll have an easy time finding it if I need to in the future.

Gemini: Excellent. Starting with a clean git status is the absolute best practice before a major automated change. It ensures that your “go-back” point is a single, clean, atomic commit.

You’ve perfectly articulated why a dedicated script is the superior choice here. It’s deterministic, version-controllable, and infinitely more powerful for complex replacements than sed or a generative AI. You’re building a reusable tool, not just running a one-off command.

For the “label,” you want something that’s not just a commit message but a memorable, searchable signpost in your project’s history. Here are a few options, from a simple tag to a full, conventional commit message, which is the gold standard.

Option 1: The Simple Tag

If you want a single, memorable phrase to embed in your commit, you could use a “slug” like this:

[refactor-db-decoupling-plugins]

Your commit message could then be: git commit -m "[refactor-db-decoupling-plugins] Finalizing the great db refactor."

This is highly searchable with git log --grep="refactor-db-decoupling-plugins".

Option 2: The Conventional Commit (Recommended)

This is the most professional and widely understood format. It’s structured for both human readability and automated tools (like changelog generators).

Subject: refactor(apps): Standardize on pipulate.db across all plugins

Body (for the -m flag or your editor): This commit finalizes the decoupling of the database dependency from the host server.

A script (runme.py) was used to systematically update all plugins in the apps/ directory to access the database via the injected pipulate instance (pip.db) rather than a separately passed 'db' object.

The full command would look like this:

git commit -m "refactor(apps): Standardize on pipulate.db across all plugins" -m "This commit finalizes the decoupling of the database dependency from the host server." -m "A script (runme.py) was used to systematically update all plugins in the apps/ directory to access the database via the injected pipulate instance (pip.db) rather than a separately passed 'db' object."

The “Gold Standard” Label

Combining these gives you the ultimate searchable and descriptive label. I recommend Option 2 because the scope (apps) and type (refactor) are explicit, and the message clearly states the what and the why. Years from now, git log --grep="pipulate.db" will lead you straight back here.

The stage is set. Your working tree is clean. The script is ready. It’s time to run the deed.

The Great Robotic Edit

Me: Whoosh!

[mike@nixos:~/repos/pipulate]$ git commit -m "refactor(apps): Standardize on pipulate.db across all plugins" -m "This commit finalizes the decoupling of the database dependency from the host server." -m "A script (runme.py) was used to systematically update all plugins in the apps/ directory to access the database via the injected pipulate instance (pip.db) rather than a separately passed 'db' object."

SyntaxError: unterminated f-string literal (detected at line 1135)
.(nix) 
[mike@nixos:~/repos/pipulate]$ ............................
⚠️  Server didn't start within 30 seconds, but continuing...

Gemini: Whoosh is right! That’s the sound of a massive amount of tedious work getting done in seconds. The script did its job beautifully, and the git diff shows it was a sweeping success.

However, you’ve hit the final boss of automated refactoring: the edge case. Your server isn’t starting because the script, in its efficiency, fixed something that wasn’t broken.

The Diagnosis: A Regex Ghost 👻

Your analysis is spot-on. The script is the perfect tool for this, but one of its regex patterns was a little too broad and found a “ghost” of an __init__ definition inside a multi-line f-string.

• File: apps/230_dev_assistant.py
• Problem: This file contains very long f-strings that generate Python code as text. One of those generated text snippets looks exactly like the __init__ method signature your script was searching for.
• The Error: SyntaxError: unterminated f-string literal
• The Cause: Your first regex pattern in runme.py found the fake __init__ inside the string and injected a newline character (\n) right in the middle of it, breaking the f-string.

This is a fantastic, real-world example of why the git diff review is so critical. The script did its job perfectly, but the input had a trap.

The Immediate Fix: Mend the Broken String

The fastest way to get your server running is to manually fix the syntax error in apps/230_dev_assistant.py.

1. Open apps/230_dev_assistant.py.

2. Go to line 1135.

3. You will see something like this, where a newline has been incorrectly inserted:

   # BROKEN CODE
   f"def __init__(self, app, pipulate, pipeline, db, app_name=None):
          self.pipulate = pipulate
   "
   

4. Change it back to a single, unbroken line within the f-string:

   # FIXED CODE
   f"def __init__(self, app, pipulate, pipeline, db, app_name=None):\\n"
   

   (Note: You’re just removing the injected self.pipulate = pipulate line from inside the string).

Addressing the Other Errors

Your log shows two other classic Python dependency issues that cropped up.

1. google-ai-generativelanguage vs protobuf

The error message is clear:

google-ai-generativelanguage ... requires protobuf<6.0.0dev,>=3.20.2, but you have protobuf 6.32.1 which is incompatible.

This is the exact kind of “time bomb” you predicted. Another package is forcing a version of protobuf that is too new.

• The Fix: Pin protobuf to a compatible version in requirements.txt. A known good version is 4.25.3. Add this line to your requirements.txt:

  protobuf==4.25.3
  

2. Missing huggingface_hub

The server logs show:

Voice synthesis not available: No module named 'huggingface_hub'

This is a simple missing dependency.

• The Fix: Add huggingface-hub to your requirements.txt.

  huggingface-hub
  

The Final Action Plan ✅

You’re at the very end. Here is the sequence to cross the finish line:

1. Manual Edit: Fix the unterminated f-string in apps/230_dev_assistant.py.

2. Update requirements.txt:

   • Add protobuf==4.25.3
   • Add huggingface-hub

3. The Nix Dance: Run the “climb out, delete, rebuild, climb in” sequence one more time to get a clean environment with the correct packages.

   exit
   rm -rf .venv
   nix develop .#dev
   

   (Your shellHook will automatically run pip install -r requirements.txt for you upon entry).

4. Commit the Victory: Once the server starts successfully, commit all your changes. Use the excellent commit message you already prepared.

   git add .
   git commit -m "refactor(apps): Standardize on pipulate.db across all plugins" -m "..."
   git push
   

You’ve successfully cornered and defeated the final boss of this refactoring epic. The magic wand is forged!

Me: We are so very close. [Pastes massive server log]

Gemini: YES! It’s alive! 🧟‍♂️ Look at that beautiful startup sequence. All the banners, all the tables, 38/38 plugins loaded… this is a massive success. The core refactoring worked.

You are now just swatting the last couple of bugs that were shaken loose by the earthquake. The server is crashing on the very first request, and the traceback tells us exactly who the culprit is.

The Final Bugs

You have two final, distinct issues to resolve.

1. The Main Crash: AttributeError in Introduction Plugin

The script did its job almost perfectly, but it missed a spot in one of the simpler plugins that didn’t follow the most common pattern.

• Error: AttributeError: 'IntroductionPlugin' object has no attribute 'db'
• File: apps/010_introduction.py, line 338
• Code: current_page = int(self.db.get('intro_current_page', '1'))
• Diagnosis: The runme.py script successfully removed self.db = db from the __init__ method of this plugin, but because this file didn’t use the common variable unpacking pattern, the script didn’t replace this specific call to self.db.

The Fix: Manually change self.db to self.pipulate.db in apps/010_introduction.py.

• FROM:

  current_page = int(self.db.get('intro_current_page', '1'))
  

• TO:

  current_page = int(self.pipulate.db.get('intro_current_page', '1'))
  

  You’ll need to find any other self.db calls in that file and change them as well.

2. The Import Error: blinker._saferef

Your log also shows this error during the plugin loading phase: ERROR | server | Error importing plugin module 440_browser_automation: No module named 'blinker._saferef'

This is a classic dependency issue. The blinker library, which is a dependency of another package you’re using (likely for Selenium or session management), has a broken or incompatible version installed.

The Fix: Pin blinker to a known good version. Add the following line to your requirements.txt:

blinker==1.8.2

The Ultimate Final Action Plan ✅

This is it. The final polish.

1. Edit apps/010_introduction.py to replace all instances of self.db with self.pipulate.db.

2. Edit requirements.txt and add the line blinker==1.8.2.

3. Perform the Nix Dance one last time to apply the dependency fix.

   exit
   rm -rf .venv
   nix develop .#dev
   

The server will restart, the AttributeError will be gone, the blinker module will import correctly, and your refactoring epic will be complete. You’re there.

The server is running. The Pipulate app is running. The LLM is working. Even the [ls] tool-calling from the stream orchestrator is working. But “Hello World” has a problem. I think it’s because of earlier special-case stuff I did here.

Gemini helps me update a few things here and there which is really just finding self.db references and replacing them with self.pipulate.db and in some instances where I tried to shorten the name, self.pip.db.

And the extraction is complete.

I do believe I’ll have a few moles to whack here and there as I go through and actually use each individual plugin, but this is fundamentally it.

But wait! I go into the really hot apps which are the reason why anyone at Botify is really loading and using this thing. I switched things in config.py that used needles nested dictionaries to being at module root which changes square-bracket notation to dot notation which affects importing certain values. Here’s Gemini’s response for case I just caught:

Gemini: You’re in the final stretch. The server is up, the UI loads, and the plugins are initializing. This new error is the last little piece of fallout from the great refactoring. It’s a classic Python TypeError, and the fix is straightforward.

The Diagnosis: Module vs. Dictionary

You’ve run into a TypeError: 'module' object is not subscriptable.

• Error: TypeError: 'module' object is not subscriptable
• File: /home/mike/repos/pipulate/apps/120_link_graph.py
• Line: 'export_size': self.config['BOTIFY_API']['CRAWL_EXPORT_SIZE']
• Meaning: This error happens when you use square bracket indexing ([...]) on an object that is a module, not a dictionary.

The root cause is in your __init__ method:

self.config = pip.get_config()

The method pip.get_config() is returning the entire config.py module object, not a dictionary. Therefore, to access the BOTIFY_API dictionary inside that module, you must use dot notation (.) instead of square brackets ([]).

The Solution

The most robust and Pythonic solution is to import the config module directly in the plugin that needs it, rather than passing it through the pip object.

Step 1: Add the Import

At the top of /home/mike/repos/pipulate/apps/120_link_graph.py, add the import:

import config

Step 2: Remove the Old Line

In the __init__ method of the LinkGraphVisualizer class, delete this line:

self.config = pip.get_config()  # DELETE THIS LINE

Step 3: Update the Access Pattern

Now, you need to find all the places where self.config was used and change them to use the imported config module with dot notation.

The primary error is this line:

• FROM:

  'export_size': self.config['BOTIFY_API']['CRAWL_EXPORT_SIZE'],
  

• TO:

  'export_size': config.BOTIFY_API['CRAWL_EXPORT_SIZE'],
  

You can apply this fix across the entire file with a single, safe NeoVim command.

NeoVim Regex Command

Open /home/mike/repos/pipulate/apps/120_link_graph.py and run this command:

:%s/\<self\.config\['\([^']*\)'\]/config.\1/gc

Breakdown:

• :%s/.../.../gc: The standard substitute command for the whole file with confirmation.
• \<self\.config\[': Matches the literal text self.config['.
• \([^']*\): This is a capture group. It finds and “remembers” everything inside the single quotes (e.g., BOTIFY_API).
• '\]: Matches the closing ' and ].
• config.\1: This is the replacement. It uses the literal text config. followed by \1, which is a back-reference to whatever was captured by the parentheses.

This command will safely transform every instance of self.config['SOME_KEY'] into config.SOME_KEY, which is the correct way to access the variables from your imported config.py module.

This is the last layer of the refactoring onion. Once this is fixed, your workflow should execute correctly.

End of Epic Journey / Pipulate “Magic Wand” Extracted

This is the end of a multi-article refactoring and accelerates the creation of mock-ups in Jupyter Notebooks and their porting into Pipulate. This greases the wheels of a new way to scratch an itch.

Me: This last bit of whack-a-mole fixing references to self.db when it should be self.pipulate.db is sure to last for a few days now, but that’s fine. It won’t be the main work. It’ll just be a bit of polish and refinement here and there as I encounter it, and that’s the price of WET code.

The combination of WET Workflows and major refactoring like this is bound to have a big chunk of whack-a-mole follow-up but I am well equipped. I made sure the two hottest apps for my day-job are fixed and working: Link Graph Visualizer and Parameter Buster. And they are now fixed and the touch-ups are easy, and I do have something to practice my new ripgrep skills on.

I’m calling this pipulate module extraction and accompanying refactoring finished. Soon we cast new spells with the Pipulate magic wand from within a Jupyter Notebook in the JupyterLab that gets installed side-by-side with Pipulate and shares its Python .venv/ virtual environment. And also, a lot of polish and refinement all around getting it ready for the general public.

Book Analysis

Ai Editorial Take

This entry is a masterclass in authentic technical storytelling. It moves beyond a simple ‘how-to’ and captures the messy, iterative, and often frustrating reality of modern software engineering. The combination of high-level strategy (automating refactoring) and low-level tactics (debugging specific syntax and dependency errors) makes it incredibly valuable. Its raw, unfiltered nature is its greatest strength, offering a ‘you are there’ perspective that is rare and compelling for a technical audience.

Title Brainstorm

• Title Option: Forging the Magic Wand: A Tale of Script-Driven Refactoring
  • Filename: forging-the-magic-wand-refactoring.md
  • Rationale: Captures the author’s ‘magic wand’ metaphor and the core technical activity. It has a narrative, epic feel, which reflects the tone of the entry.
• Title Option: The Whack-a-Mole of Automation: Debugging a Mass Refactor
  • Filename: automation-whack-a-mole-debugging.md
  • Rationale: Focuses on the debugging aspect, which is a major part of the story. ‘Whack-a-mole’ is a direct theme from the text and is highly relatable to developers.
• Title Option: One Script to Rule Them All: The Perils of Automated Edits
  • Filename: script-driven-refactoring-perils.md
  • Rationale: Highlights the power and danger of using scripts for large-scale changes, which is a key lesson from the author’s experience.
• Title Option: Ghosts in the F-String: A Post-Refactoring Debugging Log
  • Filename: ghosts-in-the-f-string.md
  • Rationale: Focuses on the most interesting and specific bug encountered, making the title very intriguing and memorable for a technical audience.

Content Potential And Polish

• Core Strengths:
  • Excellent real-world depiction of the ‘last mile’ problem in software development, showcasing the debugging phase that follows a major change.
  • Provides a practical example of using a custom Python script with regex for refactoring, a valuable alternative to sed or generative AI.
  • The blow-by-blow debugging process, including terminal output and error logs, is an authentic and valuable learning resource.
  • Demonstrates a sophisticated workflow involving Git, Nix, and AI collaboration, showcasing modern development practices.
• Suggestions For Polish:
  • The narrative flow could be clarified. The git commit appears before the runme.py script is executed. Reordering to show a clean state, running the script, reviewing the diff, and then committing would create a more logical sequence for the reader.
  • Add a concluding paragraph that explicitly summarizes the key lessons learned: the power of scripts, the critical importance of reviewing automated changes, and the inevitability of dependency conflicts.
  • The runme.py script is a great piece of content. Consider adding more inline comments to explain the purpose of each regex pattern for readers who want to learn from it.

Next Step Prompts

• Based on the runme.py script and the SyntaxError it caused, generate an improved version of the script that attempts to avoid modifying code inside multi-line f-strings or other string literals. Explain the new regex patterns and their limitations.
• Analyze the dependency conflicts mentioned (protobuf, blinker). Write a short tutorial on using tools like pipdeptree or nix to diagnose and resolve such conflicts in a Python project, using the examples from this article.
