Re: can we do binding correction?
by Andres Conrado Montoya 20 Mar '24

There is some mention of a mechanism to get binding correction from an old article in the wiki about emulating the Koma TypeArea from LaTeX, you can see it in https://wiki.contextgarden.net/KOMA-scrartcl_Type_Area There is also some discussion about the subject in SE: https://tex.stackexchange.com/questions/38682/rules-of-thumb-for-size-of-bi… However, that discussion is 12 years old and the links referenced as sources are dead now. I have found with experience that a formula to calculate the binding correction for a saddle stitch binding, not more than 4 pages in a signature (only one fold in the middle) usually is 1/2 the circumference of a circle with radius *r*, being *r* the thickness of the paper times the amount of physical signatures. Something like: \frac{π \times t \times s}{2}. I have not tried a formula for more folds in a signature. The thing is, you have to recalculate for each signature fold. The innermost will have displacement zero, the second one a little bit more, the third a little bit more, and on and on until we reach the outermost signature. However, it is necessary to say that unless you are using a particularly thick paper, or you are using too many pages for a saddle stitch bind (my personal and professional opinion would be no more than 80, but better 60), the displacement is usually negligible. For example, let's say the paper thickness is 0.1 mm (which is 0.0001 meters) and there are 40 pages in 10 signatures. The radius would be 0.0001 meters per signature * 10 signatures = 0.001 meters. Then, half the circumference would be 1/2 * 3.14159 * 0.001 meters ≈ 0.0016 meters or 1.6mm at the last signature. Unless there was a displacement of more than, say, 4 mm, I wouldn't worry too much about it. -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

can we do binding correction?
by Hraban Ramm 20 Mar '24

20 Mar '24

Hi, this question was rised in my ConTeXt beginners workshop* at Chemnitz Linux Days today: Can I configure binding correction for saddle-stitched or thread-bound booklets, and if, does it only work with arranging (imposition) or can I enable it somehow for the layout (if the printshop does the imposition)? Also I recognized I'm not sure about the difference of the layout parameters backspace and cutspace. Hraban *) 8 participants who endured 3 hours of me mostly talking… Further questions that I couldn't answer for sure were about PDF/A or PDF/UA and how color profiles are handled within ConTeXt and at printshops (my monitor is profiled, but I know I have to edit images "too bright" to have them look right in print). I need to investigate further before I can ask precise questions. When JUH yesterday had his shorter talk about "corporate publishing with Markdown and ConTeXt", the lecture hall was stuffed.

Comments placed in the margin
by Jeroen 19 Mar '24

19 Mar '24

For comments that are placed in the margin, the \inleft{}, \inouter{} etc will place text in the margin in bold. Can this text be placed in the margin in regular text or possibly in slightly smaller font size compared to the regular text in the document?

Adjusted Chapter Headings
by Jeroen 19 Mar '24

19 Mar '24

I have some style adjustments for the chapters. The chapter "numbers" need to be Boek I, Boek II, etc. A vertical separator was introduced with an inframe. The chapter title at the right side does not vertically align properly with the chapter number in the frame (inside the frame is vertically centered, the title not). Is there a way to align the chapter title with the chapter number? \starttexdefinition MyNumberChapterCommand #1 \inframed[frame=off,rightframe=on,framecolor=black, rulethickness=1px,height=30pt]{#1\enspace} \stoptexdefinition \setuphead[chapter][style={\bfc},numbercommand=\MyNumberChapterCommand, page=no] \starttext \startchapter [title={Algemene Beginselen}, ownnumber={Boek I}] \samplefile{tufte} \stopchapter \startchapter [title={Organisatorische Structuren}, ownnumber={Boek II}] \samplefile{tufte} \stopchapter \stoptext

ck hyphenation in old German orthography
by Hraban Ramm 18 Mar '24

18 Mar '24

Hi, the sample file aesop-de is in old German orthography, there, ck should get hyphenated as k-k, this doesn’t work (e.g. Mücke isn’t hyphenated at all). Is there something I can configure?

Mikael’s missing math manual
by Hraban Ramm 18 Mar '24

18 Mar '24

… and another thing that came up in my workshops and in discussions at our booth: the math manual is eagerly awaited! (My book too, but I can’t answer most questions about math.) One participant tested some math alignment examples from an older paper by Aditya and found them working in her current LMTX installation but not in COW – I know it runs an older version, but Aditya’s article was even older… Hraban

issue with typing in footnotes
by Pablo Rodriguez 18 Mar '24

18 Mar '24

Dear list, I have the following sample (which was on the way of showing another issue): \starttext a \starttyping b \stoptyping c \startfootnote a \starttyping b \stoptyping c \stopfootnote \stoptext Current latest (from 2024.03.11 09:34) breaks compilation with both LMTX and LuaTeX. As far as I know, this sample should be compiled without any issue. Could you be so kind to confirm the issue or explain me what am I missing? Many thanks for your help, Pablo

PDF, runner, and TikZ patches
by Max Chernoff 18 Mar '24

18 Mar '24

Hi all, I've had a few patches applied to my installation for a little while now, so I figured that I should send them in. There's a diff at the end of the email, and the modified files are attached [but rejected by the mailing list, so sent separately to Hans] * In the definition of "featurecreep()" in "lpdf-mis.lmt", "structures.pages.tobesaved[i].status" should be "[...].state" to match the definition of "pages.save" in "strc-pag.lua". * For the "resultof" runner in "util-sbx.lmt", the current io.popen mode only works with Windows. See the definition of "l_checkmodep" in "liolib.c". * Some of the pgfplots 3D shaders appear to be broken, see https://tex.stackexchange.com/a/708121 . * The TikZ "RGB" colour model does not currently work properly. This is internally used by "\usepgfplotslibrary[colorbrewer]" among others. See https://github.com/pgf-tikz/pgf/pull/1130 .

Why is header page number appearing when I define a header?
by Joel 17 Mar '24

17 Mar '24

\starttext \setupheadertexts[Name:~____________________][Date:~__________][Date:~__________][Name:~____________________] \setupfootertexts[][pagenumber][][pagenumber] \input knuth \stoptext I used this code to create header texts that prints Name / Date on the top and page numbers in the bottom corners. But somehow when I define this code, its also adding the page number not just to the bottom of the page, but to the top of the page as well. How do I remove the page number from the header texts? --Joel
