ConTeXt news in the Fediverse
by Henning Hraban Ramm 20 Sep '22

20 Sep '22

At the meeting we talked about raising visibility for ConTeXt and the context group. I created a Mastodon account for context group and will use it to share news and interesting stuff related to ConTeXt: https://fosstodon.org/@context (i.e. @context@fosstodon.org) Never heard about Mastodon? It’s an alternative to company-owned microblogging services like Twitter and an important part of the Fediverse, where you can interact with other federated (decentral) services like Friendica, PeerTube, FunkWhale etc. You can use it with a bunch of different apps (e.g. Tusky) or via web interfaces. In that, it’s similar to Email: You choose a server of your liking and can subscribe to and communicate with users on other servers, while most of them have some focus (e.g. regional, political, interests). See also e.g. https://joinmastodon.org Please tell me if you post something somewhere that I could toot (share; Mastodons don’t tweet). Hraban (@fiee@literatur.social)

axis values (other than weight) for a variable font
by Pablo Rodriguez 19 Sep '22

19 Sep '22

Dear list, I have the following sample: \definefontfeature [book] [axis={weight=400}] \definefontfamily [mainface] [rm] [Recursive] [features={default, book}] \setupbodyfont[mainface] \starttext \input zapf \stoptext This is for Recursive a variable font by Google (https://www.recursive.design/). In addition to the weight variable in axis values, it also contains mono, casual, slant and cursive. How can I modify this values from ConTeXt? Many thanks for your help, Pablo

ConTeXt meeting and the annotated cow
by Axel Kielhorn 18 Sep '22

18 Sep '22

Hello, last week I learned something about MetaPost at the context meeting. Thanks Taco! First a little background: I write a lot of documentation and sometimes I need to include a picture with annotations. Until now I used a drawing program to add text and arrows. This has one disadvantage, these annotations are not translated. I have to prepare a set of pictures for every language. Well, that changed last week. Here is my first try (actually the 4th iteration): %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setupexternalfigures[location=default] \starttext \startMPinclusions %draft := 0; draft := 1; color mycolor; if draft = 1 : mycolor := red ; else: mycolor := .4white ; fi ; % Draw a grid to count locations def gridscaled = pair ur; ur = urcorner currentpicture; width := xpart ur; height := ypart ur; xstep := ceiling(width / 10); ystep := ceiling(height / 10); if draft = 1: counter := 1; for i = xstep step xstep until width : draw (i, 0 ) -- (i, height); label.rt(counter, (i , 0.5 cm)); counter := counter + 1 ; endfor; counter := 1; for i = ystep step ystep until height : draw (0, i) -- (width, i); label.top(counter, (0.5 cm, i )); counter := counter + 1 ; endfor; fi; enddef; % Bottom: The annotation is at the bottom of the start point def annotb (expr a, b, c, d) (text t) = label.bot (t, (a * xstep, b * ystep)); drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .8mm withcolor white; drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .5mm withcolor mycolor; enddef ; % Top: The annotation is on top of the start point def annott (expr a, b, c, d) (text t) = label.top (t, (a * xstep, b * ystep)); drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .8mm withcolor white; drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .5mm withcolor mycolor; enddef ; % Right: The annotation is on the right of the start point def annotr (expr a, b, c, d) (text t) = label.rt (t, (a * xstep, b * ystep)); drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .8mm withcolor white; drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .5mm withcolor mycolor; enddef ; % Left: The annotation is on the left of the start point def annotl (expr a, b, c, d) (text t) = label.lft (t, (a * xstep, b * ystep)); drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .8mm withcolor white; drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .5mm withcolor mycolor; enddef ; \stopMPinclusions \startMPpage % Picture draw externalfigure "cow.pdf" xsized 16cm; % Grid gridscaled; % Text annotb (1, 5, .8, 7.3, "Maul"); annotb (6, 2, 7, 3.2, "Euter"); annott (9.2, 9.5, 9.6, 3, "Schwanz"); annotb (3, -.5, 3.1, .9, "Huf"); annotb (3, -.5, 3.9, 1.1, ""); \stopMPpage \startMPpage % Picture draw externalfigure "cow.pdf" xsized 10cm; % Grid gridscaled; % Text annotb (1, 5, .8, 7.3, "Maul"); annotb (6, 2, 7, 3.2, "Euter"); annott (9.2, 9.5, 9.6, 3, "Schwanz"); annotb (3, -.5, 3.1, .9, "Huf"); annotb (3, -.5, 3.9, 1.1, ""); \stopMPpage \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% There are still some further ideas and a lot to learn for me: - multi line annotations - a transparent white background - a frame around the text - a link to the section where the part is explained - moving to one command with the orientation as an argument Comments and improvements are welcome.

Lato typescripts (MKIV/LMTX)
by Adam Reviczky 17 Sep '22

17 Sep '22

Hi, With the latest upload (2022-09-16 14:41) I wanted to compare some older projects that I've used with MKIV to the LMTX 2.10.00. In one of which I am using the Lato 2.0 font ( https://packages.debian.org/sid/fonts-lato). With MKIV I get the correct output but LMTX complains about not being able to find the font. There seems to be an issue with the typescript file type-imp-lato.mkiv.

I am cleaning the cache and do a generate and fonts reload each time. Is changing the type-imp-lato.mkiv as above the right approach to get lato working in both MKIV and LMTX? Thanks, Adam

LuaMetaTeX insert nodes patch

Hi Hans, I see that you've released the LuaMetaTeX source code, yay! I'm really impressed with how easy it is to build, and with how quickly it builds.

meeting not online
by Henning Hraban Ramm 16 Sep '22

16 Sep '22

Hi everyone who was interested in participating in the meeting remotely, I just recognized I forgot to include some addresses in the participants address, thus some information didn’t reach the adressees. The DSL connection here in Dreifelden is very weak and unreliable – even if streaming works sometimes, usually it’s just enough for email. Yesterday we streamed for one guy via mobile connections, but those who offered their phones for it have now mostly used up their data volume and need the rest for themselves. We suspected the Wifi to be the bottleneck, but when I bought and installed an ethernet cable, it wouldn’t get better. I’m very sorry, but we can’t keep that up. Hraban
