lmt_shade fails
by Keith McKay 20 Feb '24

20 Feb '24

Hi all I went to use the lmt_shade function and it fails with two error messages. the first one is: /metafun > log > error: Not a cycle/ followed by lots of trace messages, then: /metafun > log > That contour should have ended with '.. cycle' or '& cycle'. So I'll not change/ /anything just now./ // The MWE I used is as follows: \starttext \startMPpage definecolor [ name = "MyColor3", r = uniformdeviate(1), g = uniformdeviate(1), b = uniformdeviate(1) ] ; definecolor [ name = "MyColor4", r = uniformdeviate(1), g = uniformdeviate(1), b = uniformdeviate(1) ] ; draw lmt_shade [ path = fullsquare scaled 5cm, direction = "up", alternative = "linear", colors = { "red", "green" }, ]; \stopMPpage \stoptext I'm using: /system > ConTeXt ver: 2024.02.14 13:38 LMTX fmt: 2024.2.15 int: english/english/ on a mac mini M1. Any thougths? Best wishes Keith McKay

Text in Margin
by Jeroen 20 Feb '24

20 Feb '24

In a textbook I am looking to place a large left margin at every page of each chapter. At left printed pages a left margin and at right printed pages a right margin, so like a double sided construction. In this margin I would like to place: 1. Keywords and small descriptions to emphasize some text from the textflow 2. Figures 3. An expansion of a table that is placed in the main textflow but that needs to cover a wider range then the text area so it expands into the margin What is the the easiest way to achieve this? Jeroen

There is a package on github https://github.com/andythomas/TeX-sidenotes that can help you with that. Check the "context" folder on that repo. Also, you can find an example of its use at https://github.com/zvonkok/perf-panacea Caveat emptor: It has not been updated in 12 years. It should work for the most part, I tried to do something with it a while ago but that project was cancelled. I have not tested it myself but maybe later in the week I can take a look at 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.

Fwd: Re: Working with layer sets with Metapost
by Emanuel Han 19 Feb '24

19 Feb '24

I just made a strange observation in the output pdf of the attached layer_set.tex, which is that when opening it with a pdf viewer like skim or macos preview and showing miniatures, all pages except the last one show page number 1 (the last showing page number 2). Which was not the case with the output pdf of the attached multipage_metapost_mwe-very_simple.tex.

New upload doesn't work on macOS 10.13.6

Hi list, after having tried to update with the new upload, ConTEXt doesn't run anymore. According to the output the new version requires a more recent system. I still use macOS 10.13.6 (High Sierra).

Memory consumption in new upload
by Shiv Shankar Dayal 17 Feb '24

17 Feb '24

Thanks for new upload. I see that memory consumption is much less than previous version. So once again, thanks a lot. I am curious about what has changed in recent upload, that memory consumption is about 60% of earlier versions. -- Respect, Shiv Shankar Dayal

Working with layer sets with Metapost
by Emanuel Han 17 Feb '24

17 Feb '24

Dear list, the attached .tex file is the minimal working example we discussed today in the online meeting. I realized that the approach of looping through k of p[k] is not fitting my needs, because it's not flexible enough. I need another approach, one which works with layer sets. I would stop using p as an array, because with the layer sets approach we don't have a fixed order of the layers. So the definition of the layers would be something like picture layerA; layerA:=image( label("Word 1", z1); ); picture layerW; layerW:=image( label("Mot 2", z2); ); picture layerM; layerM:=image( label("Parola 3", z3); ); picture layerC; layerC:=image( label("Wort 4", z3+z1); ); picture layerY; layerY:=image( label("Nummer 5", z2+z3); ); picture layerU; layerU:=image( label("number 6", z2+z1); ); After that, I would define layer sets and layer subsets. This will be done manually for each layer set and each layer subset. I don't know the proper syntax to do that. Let's assume we could use a variable type called "myset". myset layersubsetGamma; layersubsetGamma:={layerU,layerM}; In my logic, the layers will be drawn in the order of their appearance within the {}. In the example, drawn content of layerM might cover drawn content of layerU. Contrary to a layer subset, each layer set will result in a PDF page, and thus the layer sets are related to each other by an inner order. That's why I would use an array variable here with []. I don't know how to append a set. In the following example, I assumed there would be a function myappend(<initial set>, <the things what the initial set should be appended with>) myset layerset[]; layerset1 := {layerW,layerA}; layerset2 := myappend{layerset1, layerY}; layerset3 := myappend{layerset2, layersubsetGamma}; layerset4 := myappend{layerset2, layerU}; layerset5 := myappend{layerset4, layersubsetGamma}; Finally, I would need each layerset[k] typeset on its own pdf page. And of course on each page k, only the layers which appear in the definition of the layerset[k] should be drawn on top of each other in the order as they appear in that definition. I'm very curious to hear your suggestions. Thanks Emanuel
