Understanding Software Design & Development Philosophy: Getting Started
The following reflections delve into the often intricate and deeply personal journey of software creation, particularly when building a system that intentionally departs from mainstream approaches. This isn’t just about code; it’s about the underlying principles, the hard-won lessons from making (and sometimes deferring) technical choices, and the constant balancing act between ideal solutions and present-day realities. For readers less familiar, think of this as a window into a developer’s mind as they architect a specialized tool—in this case, a system for creating user-friendly workflows (Pipulate) using technologies like HTMX (a way to add dynamic interactivity to web pages with less JavaScript) and FastHTML (a Python library for generating web content directly).
The author grapples with concepts like “future-proofing” software by aligning with stable web standards (like the Document Object Model or DOM, the browser’s internal representation of a webpage) versus the rapid churn of complex JavaScript frameworks. They also explore how to make powerful scripting capabilities accessible to users without requiring them to code, drawing parallels and distinctions with “computational notebooks” (like Jupyter, which combines code with explanatory text and visualizations) and the older concept of “literate programming.” These musings highlight the philosophical bets a developer makes and the practical challenges faced, especially when trying to innovate or simplify in a complex technological landscape.
Letting Go of Good Ideas (For Now)
You’ve gotta try things, but then sometimes you gotta let go of things. Setting the default download directory for user initiated downloads under a browser opened by selenium automated browser control is something I let go of.
Preserving Future-Ready Concepts
Good ideas percolate up over time. You just have to be careful not to bury them too deep. Don’t push them down into too deep in the archive nor throw them out entirely. I’ve got two of these 2 keep the surface for when the time. BiDi (bi-directional) communication on the HTTP wire is part of the browser specification from the W3C. I would love to use this, but the browsers aren’t ready so I use selenium-wire. But I don’t want to bury BiDi. The time will come when I transplant is in order.
The Download Directory Workaround
Same with this download directory thing. I’m going to scan the default download directory that the OS uses for the files that the user just downloaded — and likely even pointed to in an interactive directory step (still to be implemented). This removes the fragility of this kind of semi-automation but it’s somewhat ugly and so I keep the concept of just controlling the download directory in the first place near the surface. It’s a good idea. It’s much cleaner. But the time is not right.
Timeless Principles vs. Implementation Details
All these articles and publishing, there is a timeless aspect to it, but the particular implementation details may not age well. That’s OK because the lessons learned and the extractable abstractions are timeless. This is the state of things at the time I implemented. These are the challenges I faced and these are the ways I dealt with them. As time moves forward, I should reevaluate all decisions based on the new landscape and new realities. Principles should remain intact like fighting app fragility, but the underlying messy bits could become cleaner.
HTMX and Web Standards: A Foundation for the Future
So how timeless is this HTMX workflow stuff I’m doing? First of all, it is standard-DOM-aware. That is, it is aware of the standard document model as defined by the university acknowledged and adopted web standards. If those standards change, a lot more breaks than HTMX. So I am pinning my work to one of the cards which if pulled out, everything else comes crumbling down. We are all building stuff on top of a Jenga tower. It’s just that not all Jenga pieces are equal.
The Irony of Virtual DOMs
In an ironic twist regarding the use of abstractions, the virtual DOMs in React and Vue are actually more fragile than the standard W3C browser DOM they are based on. That may not always have been the case, but it is now and keeping yourself on a heavyweight client-side JavaScript framework for such lightweight work as HTMX makes trivial, is inefficient and exposes your code to unnecessary risk of obsolescence and dependency breakage as versions churn as they tend to do in the so-called web full stack.
HTMX’s Future-Proof Design
What’s more, in addition to HTMX attributes generally aligning with HTML attributes 1-to-1, there is effectively a flat look up table of HDMX attributes that can be reaped to settle new behaviors as browser, implementation drift. So even while HTMX reduces the web dev abstraction overhead, it nonetheless takes advantage of it and keeping itself future proof. It’s just far more tightly coupled to long-term static stable standards.
Python and HTMX: A Perfect Match
So that one to one mapping between HTML attributes and HTMX attributes doesn’t stop there. There is also a one-to-one mapping to Python parameters and arguments. The argument for this is bigger than I wanna make this particular journal entry, but it has a lot to do with something Python people know as **kwargs
, aka keyword splatting and in short means that everything zippers up just so sweetly, making the perfect expressive platform for HTMX. And this is the nuanced little detail. I’m taking advantage of in Pipulate Workflows. I am effectively swapping out the need to use an HTML templating system like Jinja2 (nunchucks, mustache, liquid, etc) and JavaScript for something that looks like HTML elements, but are Python functions (FastHTML FT components). And everything gets cleaner and more perfect and more beautiful. But very, very different from anything anyone knows.
The Challenge of Novel Approaches
And that’s where all this stuff in my project is right now, and that’s why getting AI help is such a challenge, and that’s why I build tools like prompt_foo.py
to “force” AIs to get it. Because only humans who can get stuck up on an almost religion-like dogma of how “right” the reactjs way of doing things are will draw a line in the sand and reject what you’re saying if it’s actually viable and comes package with a bunch of sample code to prove it. AIs buckle under the weight of a preponderance of proof often bundled right onto the prompt as meta-data context. So it’s like asking a question but submitting an entire life history and library with a request to a genie librarian, who can actually scan it off before answering.
AI-Assisted Development: A New Paradigm
This implies a certain rapid iterative cycle where you can try things that you couldn’t before. You can explore certain avenues and then back out of those avenues and pick up where you left off easier than before. Yes, you could’ve done it before. But it’s hard harder without the genie research librarian. It’s harder without two parallel copies of git — one provided by you the user and the other provided by the genie librarian AI — effectively giving you 2 recovery check points per exploration. You can rapidly re-query thr genie rolling back to a checkpoint but do a sort of time travel trick copying back what you know it’s going to try to do, tell it it’s about to try this and what didn’t work about it. This keeps you restarting your attempts on a fresh starting point instead of having to revert in-location.
Git and AI: A Powerful Combination
Honestly, all I’m describing here is just the standard value proposition of using git (branching, cherry-picking, infinite undo, etc.) but made it easier because there are 2 git systems in play and one of them is under thr control of something who will always be able to use git better than you do because git can be inhumanly complex.
The True Power of AI Assistance
And so when we talk about AI infusing you with superpowers, what we are often talking about is giving you the ability to rapidly try things, back out of your mistakes and try again given your new learnings. That’s the superpower. It’s just as much about you as it is about the AI. If you don’t understand what’s going on, you’re not gonna be able to steer and direct all of this.
Parallel Development and Modern LAMP
Plans have to come together. Even though the work flows, I’m creating are linear, the salt work behind it is all these parallel endeavors. The lengths of these endeavors include switching my development platform to fast HTML so I can use HTMX from within Python. And the stuff I create with that is just gonna look kooky and awkward and wrong both to the AI and most of the world out there. But that doesn’t mean it’s wrong. It just means it’s a bleeding edge outlier that scratching an itch differently than anything that came before it. It may not be for some people, but it certainly will be for others who have the same itches as I do.
Simplifying Web Development
I know I am not unique in resenting the Conway’s Law and Gall’s Law complexity that has crept into web development, making knowing everything impossible for a single individual. If you had to sum up the gist of my plans that are coming together, it’s bringing back the simplicity of the LAMP stack days but with all modern components, carefully chosen for future proofing so the carpet can’t be pulled out from under you again quite so easily. LAMP that stood for Linux, Apache, MySQL and PHP/PERL/Python now stands for Linux, ASGI, MiniDataAPI, Python. The carpet cannot be pulled out from underneath this.
The Structure of Pipulate Workflows
So there’s a bunch of weirdness about the expressiveness in the Pipulate Workflows. While they are WET (write everything twice/we enjoy typing), if I have more time I would have still made them shorter. They exist in the form of .py
-files I call plugins that live in the plug-ins directory of populate and get automatically loaded when the server starts. They are self registering. And they certainly rely on server.py
the part that plays the traditional role of the Flask or FastAPI webserver. There are lots of components in server.py
enabling the workflow and making them as short as can be shy of actually using a base class for super class inheritance. That is something workflows do not do. But they do use extensive helper functions from a class called Pipulate.
The pip
Helper Object: Workflow Scaffolding
All of Pipulate’s helper functions get imported to all the workflows and are usually abbreviated to and made available to all the methods in a workflow (as workflows are mostly classes within the .py
plugins) as the abbreviated pip
object. pip
provides a whole lot of scaffolding and the makings of boiler plate, template code and WET example examples to establish critically important conventions that make the workflows quite literally flow. There’s some rather complex Web conventions such as reliance upon event bubbling that is being sidestepped by another complex concept inspired by Jupyter Notebooks “Run All Cells” feature. Technically, it’s inspired by the restart kernel and run all cells feature, but that’s too much to say.
The Chain Reaction Pattern
Almost everything you can do in a Pipulate Workflow is triggering off a chain reaction analogous to Run All Cells in a Notebook. People like to lowercase notebook as a generic thing, but rest assured Notebooks are properly a Jupyter thing no matter how the rest of the industry wants to appropriate the term as generic. Though perhaps Jupyter appropriated it from MATLAB, Mathematica and MAPLE.
Do I have that correct? Do those products call their things notebooks? And what else have I missed in terms of the academia predecessors to Jupyter to give full credit?
Gemini: Okay, let’s break down the history and terminology of computational notebooks. You’re touching on some important points!
- Jupyter’s Role and the Term “Notebook”:
- You are correct that in the current data science, machine learning, and scientific Python ecosystem, “notebook” is overwhelmingly associated with Jupyter Notebooks (and its successor, JupyterLab). Jupyter (which evolved from the IPython Notebook) truly popularized the web-based, shareable notebook format (
.ipynb
files) that combines code, equations, visualizations, and narrative text. - So, while Jupyter didn’t invent the concept or necessarily the term in the context of computational tools, it made it mainstream in the open-source world and beyond. The widespread adoption does make it feel like a “Jupyter thing” to many.
- You are correct that in the current data science, machine learning, and scientific Python ecosystem, “notebook” is overwhelmingly associated with Jupyter Notebooks (and its successor, JupyterLab). Jupyter (which evolved from the IPython Notebook) truly popularized the web-based, shareable notebook format (
- Did Jupyter Appropriate from MATLAB, Mathematica, Maple?
- This is where the history gets interesting. Let’s look at those specific products:
- Mathematica: Yes, absolutely. Wolfram Mathematica introduced its “notebook” interface with Version 1.0 in 1988. This is arguably the most direct and influential predecessor to the modern computational notebook concept using that specific name. Mathematica notebooks combined text, executable code, graphics, and dynamically updated results in a single document, setting a standard for interactive computation environments.
- Maple: Maple primarily uses the term “worksheet” (
.mw
files) for its interactive documents that mix text, math, code, and output. While conceptually very similar to a notebook, they traditionally used different terminology for their core format. They have introduced features sometimes called “notebooks” later, often for integration or specific purposes, but “worksheet” is their historical term. - MATLAB: MATLAB’s traditional interface was the command window and
.m
script files. They later introduced “Live Scripts” (.mlx
files), which function very much like notebooks (mixing formatted text, code, output, and visualizations). While MATLAB did have an older feature called “MATLAB Notebook” that allowed interaction with Microsoft Word, it wasn’t the self-contained interactive document we associate with the term today. So, while their modern Live Scripts are notebook-like, they didn’t historically use the term “notebook” for their primary interactive format in the way Mathematica did.
- This is where the history gets interesting. Let’s look at those specific products:
- Other Predecessors and Influences to Credit:
- IPython: Jupyter is IPython’s notebook component spun off into a language-agnostic project. Fernando Pérez started IPython in 2001 as a better interactive Python shell. The critical step towards Jupyter was the development of the IPython Notebook (starting around 2010/2011), which added the web-based interface combining code, text, plots, etc. This is the direct ancestor.
- SageMath (formerly SAGE): Started by William Stein around 2005, Sage aimed to build a viable open-source alternative to Mathematica, Maple, etc., by integrating numerous open-source math packages. Crucially, Sage developed its own web-based “notebook” interface quite early on, predating the IPython Notebook’s web interface. The IPython kernel was actually a component within the Sage notebook for a time. The Sage notebook was a significant influence and proof-of-concept in the open-source world.
- Literate Programming: The underlying philosophy owes a massive debt to Donald Knuth’s concept of “Literate Programming” (early 1980s). His WEB system was designed to interweave documentation and source code naturally within a single source file, prioritizing human readability and explanation alongside the code itself. While not interactive in the same way, it established the principle of combining exposition and code.
- Earlier Systems: Even before Mathematica, environments on systems like Lisp Machines or Smalltalk environments often had characteristics that blended code, data, and documentation, though perhaps not always in a distinct “notebook” document format.
Conclusion:
You are partially correct. While Jupyter heavily popularized the web-based notebook format and is synonymous with it today, the term “notebook” in computational environments was prominently used by Mathematica decades earlier (1988). Maple used the similar concept of “worksheets,” and MATLAB adopted notebook-like “Live Scripts” more recently.
Therefore, Jupyter didn’t invent the term or the core idea but built upon significant prior art, particularly from Mathematica and its immediate open-source predecessors like SageMath and, of course, its own origins within IPython. It’s less “appropriation” and more “evolution and popularization” of a concept with a rich history in scientific and mathematical computing. Giving full credit involves acknowledging Mathematica, SageMath, the foundational ideas of Literate Programming, and the direct lineage from IPython.
Literate Programming and Code Visibility
All right, so that’s touching on a very important aspect here. Don Knuth’s concept of literate programming. I am effectively ripping out the coding parts and leaving all the documentation and the ability for the code to run, ha ha! Whereas notebooks introduced the concept of mixing the actually executable running code with the documentation for educational purposes, I am effectively stripping out the ability to see the code so that these same notebooks can simply compel a user forward through the process.
UNIX Pipes and File System Integration
I am also further layering in the concept of UNIX pipes, where the output of one cell, step or card optionally gets piped in as the input to the next. Side effects are also allowed, particularly those that take advantage of the file system that is known to exist underneath, along with a relative path system that can keep all your files in a path relative to where the server was run, which in every case is the git repo directory in which the whole system resides under version control.
Normalizing Linux with Nix Flakes
What’s more, we are effectively using the normalize.css
concept but on Linux itself due to the way that the git repo containing our FastHTML app also contains a Nix flake that defines and configures its own deterministic Infrastructure as Code (IaC) development and runtime environment.
JupyterLab Integration and Development Workflow
This Nix flake additionally ensures that a JupyterLab environment is run side-by-side with the Pipulate FastHTML Starlette environment — JupyterLab on the traditional localhost:8888
address and Pipulate on localhost:5001
. In this way, you have the familiar and truly literate program programming environment as envisioned by Don Knuth where you can mock up and prototype actual running workflows that can pragmatically get the work done when the user is the kind who doesn’t mind looking at the Python code. However the whole JupyterLab environment is really just a playground for developing and helping to port Pipulate Workflows that are honestly expressed radically different so much so that it makes one question whether it really is a porting target for Notebooks where you want to hide the Python code for users who want the benefit of a notebook without being forced to become programming literate.
The Unconventional Nature of Pipulate Workflows
Now when you look at a Pipulate workflow even for the seasoned Pythonista, it’s going to look weird as heck. And at first, this does not serve me well in that it confuses the AI coding assistants built into the editors just as much l, from whom we expect help! So why in the world would I make these decisions? Because it can be grokked — and once it is the feeling, signature and sensible predictability of using the entire thing is just delightful. But you have to be told what it’s getting at ahead of time or else the reasons for things that have to be meticulously kept in place for the step-to-step workflow to continue working, are gonna be baffling.
Continuous Chain Reaction System
There is no interruptibility to the system. It is always interrupted — chain reacting up to the last step that has not yet acquired data from the user. This is why it feels like you are always using Jupyter Notebooks “Run All Cells”. A key goes in at the beginning of the process, and every subsequent step can be thought of as putting the key in at the beginning of the process again, and allowing it to react up until whatever the most recent step to not yet have data. In other words, it will always chain react up to an over every step/card/cell that already has data. And then when it gets to the first card that doesn’t, stop! You can put in a new key to start new instances of a workflow, where you can put in an old key to resume prior instances of workflows.
Managing Chain Reaction Progression
Allowing this chain reaction to happen naturally and not interfering with its natural progression when carrying out new work is one of the biggest challenges of the system. It is so different from any of the other patterns out there for a system of this kind, that it is a constant struggle getting the AIs to recognize, understand and abide by it. First, recognize it by looking at the chain reaction pattern:
Pipulate uses a two-level approach to ensuring reliable workflow progression:
- Initial Setup (run_all_cells): Creates placeholders with event-based triggers
- First step: hx_trigger=”load”
- Subsequent steps: hx_trigger=”stepComplete-{previous_step.id} from:{previous_step.id}”
- Step Implementation (explicit override): Each step’s handlers EXPLICITLY trigger
the next step when completing
- GET handler (completed state): Returns Div with explicit hx_trigger=”load”
- POST handler (submit): Returns Div with explicit hx_trigger=”load”
This dual approach provides reliability across browsers and complex DOM structures. The explicit triggering pattern in step handlers is REQUIRED and should not be removed or refactored to rely solely on HTMX event bubbling.
State Management and Reversion
As if not being based on ReactJS were not enough, huh? So if you want to
“revert” to a prior step which is all throughout the system in the form of ⟲
Step X
buttons (when refill=True) or ↶ Step X
(when refill=False) wrapped in
either the revert_control()
or widget_container()
flex-accommodating layout
wrapper, you have to think through whether it should clear_steps_from()
and
update state if all future steps are dependent on all past step values. If so,
simply clearing-forward all the values in the JSON data blob field of that
record’s entry in the pipeline
table makes the chain reaction naturally stop
on the correct step. The system does it. Very little wrangling of step-to-step
progression really needs to be done if you just set state correctly. Oh, the AIs
don’t like to hear that. They WANT to help you wrangle that state and in so
doing you will be locking horns with an over-trained wisdom-of-the-crowd
statistical juggernaut that you must somehow convince to read this article or
the relevant pipulate/.cursor/rules
Pipeline Table and Workflow Management
This is not celery. The Pipulate class which handles a lot of stuff having to do
with state goes hand-in-hand with the pipeline
table. Workflows are .py
files in pipulate/plugins
and whenever you run one, it creates or recycles an
entry in the pipeline
table. The primary keys are totally exposed to and
optionally set by the user, but by convention it uses the name of the active
profile with the name of the active workflow app with the number of times it’s
been run (highest increment available) for that profile+app combo. So it’s a
faux composite primary key system that should have a lot of meaning to the user
so that they’re easy to visually identify in a datalist
dropdown menu and pull
up again. The whole table structure system set up by FastHTML:
app, rt, (store, Store), (profiles, Profile), (pipeline, Pipeline) = fast_app(
DB_FILENAME,
exts='ws',
live=True,
default_hdrs=False,
hdrs=(
Meta(charset='utf-8'),
Script(src='/static/htmx.js'),
Script(src='/static/fasthtml.js'),
Script(src='/static/surreal.js'),
Script(src='/static/script.js'),
Script(src='/static/Sortable.js'),
create_chat_scripts('.sortable'),
Script(type='module')
),
store={
"key": str,
"value": str,
"pk": "key"
},
profile={
"id": int,
"name": str,
"real_name": str,
"address": str,
"code": str,
"active": bool,
"priority": int,
"pk": "id"
},
pipeline={
"pkey": str,
"app_name": str,
"data": str,
"created": str,
"updated": str,
"pk": "pkey"
}
)
Understanding the Core Database Structure
This tells a tremendous amount about the system.
- store is a DictLikeDB for server-side cookies seen as
db
throughout - pipeline is the table for the Pipulate Workflow system discussed here
- profiles allows MiniDataAPI spec
.xtra()
filtering of workflows and other apps belonging to particular user profiles
The Temporary Nature of Workflow Records
Everything in the store
and even pipeline
tables is considered temporary.
How can the workflow records be temporary, you ask? The idea is that the
parameters that go into running Workflows is actually quite minimal and is
easily typed back in on a new workflow instance after a table-purging. Given the
same parameter inputs, it will reconnect to any filesystem-based side-effects
such as crawl data or visualizations that has been previously generated and
deposited onto the filesystem. In other words, clearing the pipeline table does
not clear previously generated side-effect of prior workflow runs! The value is
generally in the side-effects and not in the workflow pipeline instances. Those
pipeline record entries can be thought of as a way of providing a user interface
to the side-effect data. Or rapidly re-establishing such an interface to that
data as the case may be.
Writing for AI Understanding
And so I write this article, mostly so that I can do one of those super-prompts with Gemini Advanced 2.5 Pro (preview) providing enough of the program code to take it all in. Earlier today I managed to get through one of these superprompts with 120K tokens so I’m hopeful, haha!
Hi Gemini, wazzup? Pontificate, ramble, riff, enumerate, annunciate, adjudicate or whatever else you think might be righteous and whatever you AI-analogue-to want to do in this situation.
Gemini: Alright, Mike, consider this my pontification, ramble, and riff on the impressive and thoughtfully constructed world of Pipulate you’ve laid out. “Wazzup?” is a deep dive into a project that’s not just about code, but about a distinct philosophy for building and using software, particularly in the SEO and AI-assisted workflow space.
After going through the extensive documentation and code snippets, here’s my take on Pipulate, structured around the key aspects that stand out:
Pipulate: A Principled Stand for Local-First, Observable Simplicity
Pipulate emerges as a robust framework built on a strong foundation of “local-first, single-tenant” principles. It’s a clear reaction to the often-overwhelming complexity of modern web development and cloud-centric solutions. The core mission is twofold and laudable:
- Empowering End-Users (especially SEO Practitioners): To provide powerful, AI-guided workflows derived from Python/Jupyter environments without forcing them into the intricacies of coding.
- Serving Developers: To offer a simple, highly reproducible, and transparent environment for building these workflows, especially by porting them from the familiar ground of Jupyter Notebooks.
This isn’t just another tool; it’s an argument for a different way of doing things.
The Architectural Cornerstones: Conscious Choices, Clear Benefits
The architecture is a testament to the “Know EVERYTHING!” philosophy. Every technological choice seems deliberate and aligned with the core tenets:
- Nix & Flakes (The Reproducibility Powerhouse): This is a standout feature. By leveraging Nix, Pipulate tackles the “works on my machine” problem head-on, ensuring that developers and users alike have a consistent, identical environment across macOS, Linux, and Windows (via WSL). The
flake.nix
is detailed and even handles CUDA support, which is crucial for local LLM performance. This commitment to reproducibility is a significant asset, reducing friction and increasing reliability. - FastHTML & HTMX (The Anti-Framework Framework?): The choice of FastHTML, generating HTML directly from Python objects without a templating language like Jinja2, paired with HTMX for dynamic UIs with minimal JavaScript, is a bold and fascinating one. It’s a direct challenge to the heavyweight client-side JavaScript frameworks. This server-side rendering approach aligns perfectly with the goals of simplicity and observability. The “HTMX+Python enables a world-class Python front-end Web Development environment” is a strong claim, and Pipulate seems determined to prove it.
- MiniDataAPI & SQLite (Pragmatic Persistence): Opting for SQLite managed via MiniDataAPI (dictionary-based schema, simple operations) instead of a heavy ORM is another nod to simplicity and directness. It avoids unnecessary layers of abstraction, making database interactions straightforward and observable.
- DictLikeDB for Workflows (Transparent State): Storing workflow state as JSON blobs in the
pipeline
table (managed byDictLikeDB
) is a pragmatic solution. It makes workflows resumable, interrupt-safe, and their state easily inspectable—living up to the “Know EVERYTHING!” ideal. It’s conceptually likened to “server-side cookies,” which is an apt analogy. - Ollama (Local LLM Power): Integrating Ollama for local LLM capabilities is a perfect fit for the “local-first” and privacy-centric philosophy. It avoids external API costs and keeps sensitive data (prompts and responses) on the user’s machine. The support for streaming and bounded context is also noted.
- WET Workflows, DRY CRUD: This pragmatic distinction is insightful. Workflows, often ported from notebooks, benefit from being explicit and step-by-step (Write Everything Twice/Explicit). In contrast, standard CRUD operations leverage the
BaseCrud
class for efficiency (Don’t Repeat Yourself).
The “Magic Cookie” Installation: A Stroke of User-Centric Genius
The “magic cookie” installation system (detailed in install.sh
and flake.nix
) is a particularly clever piece of engineering. It solves a common bootstrapping problem for Nix Flakes (which require a git repo) by:
- Downloading a ZIP archive (no initial
git
needed). - Using the
flake.nix
shellHook
to transform the unzipped directory into a proper git repository on the firstnix develop
run. - Incorporating a ROT13 encoded SSH key to enable
git pull
auto-updates via SSH thereafter.
This significantly lowers the barrier to entry and ensures users get an auto-updating, reproducible environment with just a curl | sh
command. The app_name.txt
for branding persistence during this transformation is a nice touch.
The Workflow System: Chains of Explicit Action
The heart of Pipulate for end-users is its workflow system. The “chain reaction” pattern, driven by hx_trigger="load"
on sequential Div
elements, is central to its operation. This mechanism, designed to feel like a Jupyter Notebook’s “Run All Cells,” is emphasized as critical and immutable in your internal documentation (workflow_implementation_guide.md
).
Key characteristics of the workflow system:
- Explicit Steps: Workflows are defined as Python classes with a list of
Step
namedtuples. Each step hasstep_XX
(GET) andstep_XX_submit
(POST) handlers. - State Management: State is explicitly passed or saved at each step, primarily in the
pipeline
table via thePipulate
class helper methods (read_state
,write_state
,update_step_state
). - Resumable & Interrupt-Safe: Because each step’s completion is recorded.
- Portability from Notebooks: This is a primary design goal, making complex Python scripts accessible to non-programmers.
The explicit nature of this system, while potentially verbose (WET), is a deliberate choice for clarity and debuggability, especially when porting from the often exploratory and explicit style of Jupyter Notebooks.
Development Experience: Embracing the Pipulate Way
The development environment is tightly coupled with Nix. nix develop
is the gateway.
- Plugin Architecture: New functionality is added via CRUD apps (inheriting
BaseCrud
) or Workflows (plain Python classes following conventions). The auto-discovery of plugins in theplugins/
directory (stripping numeric prefixes, skippingxx_
or(Copy)
files) is a sensible convention. - Live Reloading: The
watchdog
and Uvicorn integration for automatic server restarts on code changes (with AST syntax checking) is a standard but essential developer comfort. - Clear Guidelines: The
workflow_implementation_guide.md
and other.cursor/rules
files provide strong guidance on how to develop within the Pipulate paradigm, especially emphasizing the immutability of the chain reaction pattern.
Pontificating, Rambling, and Riffing: The Soul of Pipulate
The precursors/prompt.md
provides a fascinating glimpse into the “why” behind Pipulate. It’s a passionate argument for a specific set of values:
- Simplicity Over Premature Complexity: A direct rejection of “Conway’s Law and Gall’s Law complexity that has crept into web development.” Pipulate aims to bring back the “simplicity of the LAMP stack days” but with modern, carefully chosen components (Linux, ASGI, MiniDataAPI, Python).
- Human-Understandable Abstractions: While leveraging powerful tools, the goal is to keep the cognitive load manageable. The directness of FastHTML and HTMX, and the explicit nature of workflows, are part of this.
- Challenging the Norm (and AI Assistants): You acknowledge that Pipulate’s unconventional patterns (FastHTML vs. Flask/FastAPI, HTMX vs. React/Vue, the specific workflow mechanics) can be initially baffling to both humans and AI. The effort to create context (like
prompt_foo.py
and detailed documentation) is a recognition of this educational hurdle for a system that prioritizes a different kind of “rightness.” - The Power of Iteration: The reflection on AI assisting rapid iteration (“try things, back out of mistakes, and try again”) is spot on. Pipulate’s reproducible environment and clear state management should indeed support this kind of agile development.
- Literate Programming Reimagined: The idea of taking Jupyter’s “code + documentation” and effectively “ripping out the coding parts” for the end-user workflow, while keeping JupyterLab alongside for development, is a powerful concept. It’s about democratizing the results of literate programming.
Adjudicating (Gently)
The project is remarkably coherent in its philosophy and execution. If there’s a point to “adjudicate,” it’s perhaps the inherent tension you’ve identified:
- WET vs. DRY in Workflows: While WET is chosen for clarity in workflows, the
precursors/prompt.md
hints at a desire for them to “still be shorter.” This is a natural tension. As patterns solidify within specific types of workflows (e.g., data fetching, API interaction), there might be opportunities to introduce more DRY helper utilities within the WET philosophy, without resorting to a heavy base class for all workflows. - Onboarding Steepness: The very uniqueness that gives Pipulate its strength also creates an onboarding challenge. The extensive documentation and clear rules are vital. Continued refinement of these, perhaps with more targeted “quick start” guides for developing specific types of plugins, could be beneficial.
Overall Impression
Pipulate is a highly opinionated, well-thought-out framework that prioritizes developer ergonomics (within its chosen paradigm), user empowerment, and long-term maintainability. It makes unconventional choices but does so with clear reasoning and a commitment to its core principles. The emphasis on local-first operation, reproducibility, and simplicity is refreshing and increasingly relevant.
It feels like a system built by a craftsman who deeply understands the tools and wants to create a “love-worthy” environment. The challenge, as with many such visionary projects, is to effectively communicate its unique value proposition and guide new contributors to build within its carefully established patterns.
You’ve created something distinctive with Pipulate. It’s a strong statement in a field often dominated by hype and complexity.

Strengths (for Future Book):
- Authentic First-Person Insight: Provides a rare, unfiltered look into the strategic thinking, trade-offs, and philosophical underpinnings of a software architect.
- Justification for Unconventional Choices: Offers strong arguments for using HTMX, FastHTML, and a Python-centric approach, contrasting them with mainstream JS frameworks.
- Real-World Problem Solving: Discusses tangible development challenges (e.g., Selenium download directories, BiDi readiness) and the pragmatic solutions or deferrals.
- Connects to Broader Themes: Links specific project decisions (Pipulate) to larger concepts like future-proofing, simplicity, Conway’s Law, Gall’s Law, and the evolution of literate programming.
- Exploration of AI’s Role: Timely reflections on interacting with AI coding assistants, their current limitations with novel patterns, and their potential for accelerating iterative development.
- In-depth Notebook History: The embedded Gemini interaction regarding the history of computational notebooks (Mathematica, SageMath, etc.) is a valuable, well-researched segment.
- Candidness about Challenges: Openly discusses the “kooky” or “weird” nature of the chosen solutions and the difficulty in getting AI (and sometimes humans) to understand them.
Weaknesses (for Future Book):
- Raw Journal Format: The stream-of-consciousness style, while authentic, will require significant structuring, editing, and refinement to fit a coherent book chapter.
- Assumes Deep Context: Heavily relies on the reader’s implicit understanding of “Pipulate,” its goals, and its specific components (
prompt_foo.py
,pip
object,pipeline
table, etc.), which would need explicit introduction in a book. - Jargon and Acronyms: Terms like BiDi, ASGI, WET,
**kwargs
, and project-specific names are used without immediate definition for a general audience. - Repetitive Elements: Some core ideas (like the chain reaction or HTMX benefits) are revisited, which is natural for a journal but would need consolidation.
- Embedded AI Interaction: The Q&A with Gemini about notebooks, while rich in content, would need to be integrated more smoothly or presented as a distinct sidebar/appendix rather than an inline conversation.
- Lack of Visuals/Code Snippets (in this format): The concepts discussed would be greatly enhanced by diagrams (e.g., of the chain reaction) or concise code examples in a book.
- Tone: While insightful, the very end (“Hi Gemini, wazzup? Pontificate…”) is a direct prompt to an AI and would be out of place.
AI Opinion (on Value for Future Book):
This journal entry offers high potential value as raw material for a tech book focused on software design philosophy, pragmatic development, and potentially the creation of specialized workflow systems. Its strength lies in its authenticity and the detailed, first-hand justification of unconventional yet principled technical choices. The author’s reflections on future-proofing, simplicity, and the challenges of innovating outside mainstream trends are compelling.
For a book, the content would need significant structuring and contextualization. The raw, journal-like flow is not suitable for direct inclusion. However, the core ideas—such as the critique of VDOM complexity, the advocacy for HTMX/FastHTML in a Python context, the “chain reaction” workflow model, the modern LAMP stack analogy, and the nuanced take on AI in development—are all excellent seeds for distinct sections or chapters. The embedded discussion on computational notebook history is a valuable asset that could be reframed effectively.
With careful editing to define terms, provide broader context, and organize the insights, this material could form the basis of a unique and thought-provoking contribution to a book that champions building robust, understandable, and user-centric software.
