Setting the Stage: Context for the Curious Book Reader

In the Age of AI, our interfaces are becoming increasingly dynamic, yet we often rely on outdated, static conventions. This entry chronicles a focused, iterative effort to refine our terminal-based displays, demonstrating how a simple shift in perspective—from fixed-width defaults to adaptive, measured footprints—can dramatically improve the user experience. It is a practical study in minimizing digital clutter while maintaining modular, extensible code for the systems of tomorrow.

MikeLev.in: Take a look a this system. Here is a standard figlet:

 _____ _       _      _   
|  ___(_) __ _| | ___| |_ 
| |_  | |/ _` | |/ _ \ __|
|  _| | | (_| | |  __/ |_ 
|_|   |_|\__, |_|\___|\__|
         |___/

Notice it is only 6 lines tall. Yet look how tall we make the Figlet-containing terminal boxes. Now granted that with so little screen space to work with, there’s not a lot of room and we might expect it to wrap and when a Standard font wraps it might look like this:

 _   _                        _           _   
| | | | ___  _ __   ___ _   _| |__   ___ | |_ 
| |_| |/ _ \| '_ \ / _ \ | | | '_ \ / _ \| __|
|  _  | (_) | | | |  __/ |_| | |_) | (_) | |_ 
|_| |_|\___/|_| |_|\___|\__, |_.__/ \___/ \__|
                        |___/                 
 ____                      _               _   
| __ ) _ __ ___   __ _  __| | ___ __ _ ___| |_ 
|  _ \| '__/ _ \ / _` |/ _` |/ __/ _` / __| __|
| |_) | | | (_) | (_| | (_| | (_| (_| \__ \ |_ 
|____/|_|  \___/ \__,_|\__,_|\___\__,_|___/\__|

…which would justify a larger terminal around it, but so far the two words that we’re using that way, PIPULTE and HONEYBOT both fit on the one line very handily. The thing though is we can tell how much space horizontally a Figlet occupies (by testing it, at very least) both horizontally and vertically, can’t we? Especially if we stick to the Standard font.

This is not an implementation request yet. This is just an exploration. Like look how tightly an ASCII art diagram gets it terminal box size controlled on the horizontal and vertical to shrink in around it and “pull tight”.

Is any of this making sense to you?

The Problem of Floating Content

Claude Opus 4.8 Low: Context verified.

Yes, this makes complete sense — and the interesting part is that the answer to “can’t we measure it?” is already implemented in this exact codebase, just not on the path the cards travel.

Here’s the asymmetry you’re putting your finger on. patronus() in ascii_displays.py does precisely the “pull tight” thing. It renders the art, measures it, and sizes the Alacritty window to fit:

max_width = max(len(line) for line in raw_lines)
total_rows = len(raw_lines)
columns_needed = max_width + 20
lines_needed = total_rows + 4

That’s the box shrinking in around the content. But the card.py path never gets that treatment. When forest.py fires ("WINDOW", "card.py:5:HONEYBOT"), it flows through dispatch_cue → conjure_window(win_script, duration=5.0, args=["HONEYBOT"]), and conjure_window’s signature defaults are columns=100, lines=30. So a 6-line, ~64-column figlet gets dropped into a fixed 100×30 box and then card.py vertically centers it with Align.center(..., vertical="middle"). That centering is exactly why it looks tall — the figlet is floating in the dead middle of 30 rows of empty terminal.

So the looseness isn’t a measurement problem. It’s that the figlet path simply doesn’t measure, while the figurate path does.

The Asymmetry of Measurement

And to your direct question: yes, a Figlet is trivially and deterministically measurable, both axes:

rendered = Figlet(font="standard").renderText(label)
lines  = rendered.splitlines()
width  = max(len(l) for l in lines)   # horizontal
height = len(lines)                   # vertical

For the Standard font that height is a reliable 6 for any single-line word, and HONEYBOT/PIPULATE both come in well under any sane terminal width on one line, so you’d get height=6 every time. If a word ever did overflow and wrap into your second example, the measurement catches that too — height jumps to 12 and you’d size (or shrink-font) accordingly instead of being surprised.

Establishing a Shared Pattern

There’s one structural catch worth holding onto, because it’s the thing that would actually shape any future implementation: the box dimensions are set by the parent before the child ever runs. Alacritty gets window.dimensions={columns=…, lines=…} baked into its launch command, so by the time card.py executes, the box already exists. card.py can’t “decide” its own size from inside. This is exactly why patronus() measures parent-side — it calls render_fn() to get the art string, measures it, then launches. To make figlet cards pull tight, the figlet would have to be rendered-and-measured in the parent (in conjure_window, or surfaced through the WINDOW grammar), not blindly inside the child. Same pattern patronus already proved.

The last thing I’d name, so it doesn’t bite later: patronus’s +20 / +4 aren’t pure tightness — they’re a deliberate anti-wrap cushion, the same cell-wrapping spacing trap you’ve written about before. So “pull tight” in practice has always meant “tight plus a known safety margin,” and there’s a genuine tension between hugging the art and leaving enough slack that a terminal cell-rounding quirk doesn’t wrap your bottom row. For a figlet card you’d probably want a smaller horizontal cushion than +20 (figlets have no internal line-length ambiguity the way hand-drawn art does), but you wouldn’t want zero.

So: the perception is right, the mechanism exists, and the gap is just that the card path is the one place still using fixed defaults instead of measure-then-fit.

MikeLev.in: Well, I would like to fix that now but thinking ahead to the future. Don’t over-engineer but do know the 80/20-rule case is just what we described; putting Figlet banner cards on the same path as ASCII art for getting its terminal sized tight around it with some padding. But at some point in the future, we’re going to want a card with a Figlet banner at the top of it and ASCII art underneath; effectively combining the 2 card paths. I know that makes it much more complicated and I don’t want that to slow down the momentum we have going here. So why don’t we do an 80/20-rule solution to get the Figlet windows correct, but maybe think ahead and drop some comments in the code about where we’re going with this. ASCII art can have an optimal figlet banner label above it in the same terminal. Or would that be Figlet banners can have ASCII art below them on the same card?

You decide.

And yes, we’re inching towards implementation now. I’ll accept a patch if we can jump right there, and if not a minimally expensive probe to clear the way for a rock solid implementation will do as well, please and thank you!

Claude Opus 4.8 Opus: Context verified.

You’ve named the asymmetry exactly right, and the fix is just to put the figlet card on the same measure-then-fit path patronus already proved. Two small surgical edits, no new dependency surface, and the wrapping case you showed is handled for free because I measure with pyfiglet’s default width (80) — the same width card.py renders with — so a measured height simply doubles if a word ever wraps to a second block.

The “you decide” call: I’m framing it as “a Figlet banner with an optional ASCII-art body.” The banner is the headline; the art is supplementary; card.py stays the home and grows a body later, rather than the patronus/figurate path growing a label. That keeps the seam in the place that’s already the “label” renderer, and the future combined card just measures the union of the two stacked blocks. I’ve dropped that intent into the comments so the path is obvious when you get there.

The Architecture of Future Cards

One assumption, already proven: the measurement happens parent-side in stream.py and needs pyfiglet. Your screenshot of a rendered figlet is the probe — card.py only emits figlet art (vs. its plain-text fallback) when pyfiglet imports successfully, and it launches via the same sys.executable as stream.py. So the parent has it. If you want belt-and-suspenders before applying: nix develop /home/mike/www/mikelev.in#quiet --command python3 -c "import pyfiglet; print(pyfiglet.__version__)".

Here’s the patch.

First, the measurement helper in the shared, rsynced module:

Target: imports/ascii_displays.py
[[[SEARCH]]]
                proc.terminate()
            except Exception:
                pass


# FIGURATE_COLOR_BITS: The color-bits player piano dictionary.
[[[DIVIDER]]]
                proc.terminate()
            except Exception:
                pass


def measure_figlet(label: str, font: str = "standard") -> tuple:
    """📏 MEASURE_FIGLET: Deterministic footprint of a Figlet banner.

    Returns (width, height) in terminal cells for `label` rendered in `font`,
    so a caller can size an Alacritty box to "pull tight" around the banner the
    same way patronus() sizes its popup around registered ASCII art. Uses
    pyfiglet's default width (80) — exactly what card.py renders with — so the
    measurement matches the child's output character-for-character, including
    the wrap-to-second-block case, which simply doubles `height`.

    Falls back to the raw label's geometry if pyfiglet is unavailable, matching
    card.py's own plain-text fallback so the box is never wildly mis-sized.

    FUTURE (combined card): when a card grows a Figlet banner on top AND
    figurate ASCII art below it on one surface, the caller measures the UNION —
    max width of the two blocks, summed heights plus a separator row — and feeds
    that to the window. This helper stays single-purpose; composition happens
    one layer up.
    """
    rendered = label
    try:
        from pyfiglet import Figlet
        rendered = Figlet(font=font).renderText(label)
    except Exception:
        rendered = label
    lines = rendered.splitlines() or [label]
    width = max((len(line) for line in lines), default=len(label))
    height = len(lines) or 1
    return width, height


# FIGURATE_COLOR_BITS: The color-bits player piano dictionary.
[[[REPLACE]]]

Second, the pull-tight logic in stream.py’s conjure_window (parent-side, before the box dimensions are baked into the launch command):

Target: remotes/honeybot/scripts/stream.py
[[[SEARCH]]]
    from imports.ascii_displays import conjure_window as shared_conjure_window

    cmd = [sys.executable, "-u", str(script_path)]
[[[DIVIDER]]]
    from imports.ascii_displays import conjure_window as shared_conjure_window
    from imports.ascii_displays import measure_figlet

    # --- 80/20 PULL-TIGHT FOR FIGLET CARDS ---
    # card.py renders a single Figlet banner, and a Figlet footprint is fully
    # deterministic and measurable parent-side — exactly how patronus() sizes
    # its popup around registered ASCII art. Do the same here: measure the
    # banner BEFORE launch and shrink the Alacritty box around it. The child
    # cannot resize a box whose columns/lines are already baked into the launch
    # command, so the measurement MUST happen out here in the parent.
    #
    # Cushion is intentionally smaller than patronus's +20: a Figlet has no
    # internal line-length ambiguity to guard against, but a few spare cells
    # still keep terminal cell-rounding from wrapping the widest banner row.
    # card.py vertically centers the banner, so matching the box height to the
    # banner (+ a little) is what makes it sit snug instead of floating in dead
    # space.
    #
    # FUTURE (combined card): a card will eventually carry a Figlet banner on
    # top AND figurate ASCII art BELOW it on the same surface — the framing is
    # "a Figlet banner with an optional ASCII-art body," with card.py as the
    # home that grows a body (rather than the patronus path growing a label).
    # When that lands, render banner + art, measure the UNION of the two
    # footprints (max width, summed heights), and size the box to that. The
    # measure-then-fit pattern generalizes cleanly from one block to two stacked
    # ones.
    if safe_script == "card.py" and args:
        fig_w, fig_h = measure_figlet(str(args[0]))
        columns = fig_w + 8
        lines = fig_h + 4

    cmd = [sys.executable, "-u", str(script_path)]
[[[REPLACE]]]

After applying, card.py:5:HONEYBOT will launch into a box roughly figlet_width + 8 by 6 + 4 = 10 rows instead of the fixed 100×30 — tight, with just enough cushion that cell-rounding can’t clip the widest row. test_forest.py is untouched on purpose: it renders the card inline (no window), so there’s no box to size and nothing there breaks.

But now we’re in double-tap land because when I publish this article with --reboot I will see the last “outer loop” infrastructure change I made with a better-timed “UPDATING” window, but I won’t see this change… oh, wait! I will see this change because it’s not really outer loop. I will restart the outer loop to see it, but really it should show on that same run during the intermissions. Nice.

How would you summarize what we did, Sonnet?

Claude Sonnet 4.6 Max: Here’s what we did:

The Honeybot’s station-break title cards (like “HONEYBOT” and “PIPULATE”) were being launched into fixed 100×30 terminal windows even though a standard Figlet banner is only 6 lines tall. The figlet floated in the center of a huge box of dead space.

The patronus() path already knew how to do it right — it renders the ASCII art, measures it, then sizes the Alacritty box to fit with a safety cushion. The figlet card path simply never got that treatment.

The fix was two surgical edits:

  1. A new measure_figlet() helper added to imports/ascii_displays.py (the rsynced shared module). It renders the label with pyfiglet at the same default width card.py uses, then returns (width, height). Falls back gracefully if pyfiglet is unavailable.

  2. Pull-tight logic in stream.py’s conjure_window() — before the box dimensions get baked into the Alacritty launch command, if we’re firing card.py with an arg, we measure the figlet parent-side and substitute fig_w + 8 for columns and fig_h + 4 for lines. The cushion is intentionally smaller than patronus’s +20 because figlets have no internal line-length ambiguity.

The key architectural decision (your “you decide”): the future path frames it as “a Figlet banner with an optional ASCII-art body” — card.py grows a body, not the other way around. Comments in both files mark the seam so the combined card is obvious when that moment comes: measure the union of both blocks, sum the heights.

The changes synced to Honeybot via nixops.sh and show up during station breaks without needing a full outer-loop restart.

MikeLev.in: Yep, that sounds right. How’s this for a chisel-strike project? It feels literally like chipping stone off the excess card-size.

Book Analysis

Ai Editorial Take

What strikes me here is the psychological benefit of the ‘pull-tight’ approach. Beyond mere pixel/cell conservation, it fosters a sense of ‘intent’ in the interface. When an application respects its content’s dimensions, the system feels less like an automated script and more like a curated, responsive environment. It’s a subtle form of digital ergonomics that makes the machine feel more human-centered.
