Tsukurimashou 0.11 release

Thursday 1 July 2021, 08:26

I've just posted the version 0.11 release of the Tsukurimashou Project - my parameterized font family for English, Japanese, and Korean, now with 2912 kanji including all those taught in the Japanese school system through Grade Five and more than half of Grade Six. This is the first release of the full project since November 2017, and the project began in 2010 - so it's kind of a big deal.

MediaWikiは有名とポピュラーなソフトです。 もちろんWikipediaがMediaWikiを使っています。 その上、多数のサイトはMediaWikiを使っています。 たとえば、僕のタロットサイト「edifyingfellowship.org」でMediaWikiが使われます。 MediaWikiはLaTeXのプラグインあります。 プラグインとLaTeXのインストール時Wikiで数学の植字が出来ます。 でもTeXLiveの全部インストールなら5.7Gが使われます。 小さいウェブサーバのでTeXLiveが大き過ぎるのようです。 このブログでMediaWikiのためにTeXLiveの最小のインストールを考えましょう。

Notes on notes on the plane

Sunday 2 August 2015, 04:09

I have posted a detailed set of notes (PDF file) describing the theory behind my Black Swan Suite, detailing the endless chase of Elmer and Daffy across Penrose, pinwheel, and other nonperiodic tilings of the plane. Fans of music and computational geometry may find the document interesting. At the very least, it was fun to typeset.

Photo gallery from TUG 2013 trip

Here's a photo gallery (salvaged from my old gallery software in June 2020) of my trip to Japan in 2013 to present at TUG.

Where do I draw the line?

Monday 21 January 2013, 14:49

It's a very common pattern in the Han writing system that a character will be made of two parts that are themselves characters, or at least elements resembling characters, placed one above the other or one next to the other. For instance, 音 (sound) can be split into 立 (stand up) above 日 (day); and 村 (village) can be split into 木 (tree) next to 寸 (inch). This kind of structure can be nested, as in 語 (language). One can do a sort of gematria with the meanings, (what exactly is the deep significance of "village = tree + inch"?) but that's not the direction I'm interested in going today. Here's the thing: in the Tsukurimashou project, these two ways of constructing characters each correspond to a piece of code that's invoked many times throughout the system, and I thought it would be interesting to look at how often the different parameter values are used.

Ideographic Description Sequences: some thoughts

Monday 19 December 2011, 15:14

I went through a bit of a crunch to get Tsukurimashou 0.5 out the door before my year-end vacation. With that done, and at least 99 kanji to do before the next planned release, I have a chance to sit back and think about some longer-term and spin-off projects. Here are some ideas on kanji searching.

UPDATE: A prototype implementation of the system described here now exists as part of the Tsukurimashou project, and you can check it out via SVN from there. Packaged releases will be available eventually.

"Grimoire" fonts

Sunday 26 June 2011, 10:15

Here's a project that provides, among other things, free vector fonts of magical glyphs from the Lesser and Greater Keys of Solomon. I found it by way of sourceforge.jp's flagging it as a similar project to Tsukurimashou.

Typographical history of the TTC

Tuesday 18 January 2011, 11:42

Here's a Web log article, with several links and a couple of posters for sale, on something I've wondered about before: the unique typeface used for station names and some other signage on the TTC.

Electric kerning

Thursday 9 December 2010, 20:57

It's not like I don't have enough projects to work on already. Nonetheless, I had an idea I thought was pretty cool, and I'm going to at least describe it here, whether I end up implementing it or not.

Okay, so: kerning. If you're setting type, you need to know where to put each glyph in relation to the previous one. In the old old days, it was easy because each glyph came on a little metal block and you'd just set them right next to each other and clamp them in place. But a computer (and, earlier, a phototypesetting machine) has the opportunity to make a decision. And if you just have a fixed bounding box for each glyph and set them side by side, you run into problems when you have situations like a capital A next to a capital V. "AV". Using the bounding boxes that would be correct for those letters in other contexts, you end up putting too much space between them. You need to squeeze them together so that part of the V projects into the space that the A, if it were next to something else, would reserve for itself. This squeezing together is called "kerning."

The Terrible Secret of OpenType Glyph Substitution

Monday 6 December 2010, 13:18

I was up until 3 this morning trying to figure out how to make OpenType glyph substitution work. That, in itself, is not news. Anyone who has tried to write substitution rules for OpenType fonts has probably gone through something similar. What is unusual, though, is that I not only succeeded, but also figured out the undocumented underlying principle so that I can predictably succeed in the future; as far as I can tell, the more usual practice is to just try things at random until one eventually either gets it working by accident, or gives up, without having learned anything useful either way.

The purpose of this entry is to provide the important information that I wasn't able to find on the Net and wish I had had. There is one important point I call the Terrible Secret, which makes all the difference to getting it to work; but rather than jump to that immediately I'm going to give the needed background first. I'll be using the terms that make sense to me, rather than the "easy" but uselessly vague simplified style used by all existing documentation I found.
