new lmtx / fonts
by Hans Hagen 22 Jan '21

22 Jan '21

Hi, I uploaded a new lmtx. I'm still playing a bit with metafonts so there are two new files context --global meta-imp-demo.mkxl context --global meta-imp-clock.mkxl Both show a bit. The question is, do we need / want more like this? What kind of interfaces are best? It's mostly about used defined symbols that are proper characters and efficiently used. Hans PS. The clock one has a hidden cut'n'paste feature that only works on acrobat which of course then makes it a kind of useless feature (plenty of them by now) because when, e.g. a mupdf bases viewer doesn't support this after all these years it's could as well be kept out of the standard. ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Missing images in Wiki?
by Andres Conrado Montoya 22 Jan '21

It seems a lot of image examples from the wiki are gone now. Most articles lost many images. Is this on purpose? -- Andrés Conrado Montoya

\clip isn’t clipping any more
by Henning Hraban Ramm 20 Jan '21

20 Jan '21

In the following example, the image is calculated after the clipped width, but the full image is shown: \setupexternalfigures[location=default] \showframe \starttext \strut \hfill\clip[width=20mm]{\externalfigure[cow][height=30mm]} \stoptext This happens in current LMTX (2020-01-18), it was still ok in LMTX as of 2020-01-11. It also works in MkIV. Hraban

lmtx
by Hans Hagen 19 Jan '21

19 Jan '21

Hi, There's a new lmtx upload with a few fixes in publication lists (TS made some tests). For those who like fonts, there is an update of the punk font (the mkiv variants dates from 2008 which is ancient on a software timeline). You can run meta-imp-punk.mkxl to get an idea. There's also a typescript: type-imp-punk.mkxl one can create different versions and play with random variants and such. The question is: do we need more metapost font magic and infrastructure? For "pdf features that browsers implement fuzzy or not at all" lovers there is test \startalternate[text={A}] \dorecurse{10}{A } \startalternate[text={B}] \dorecurse{10}{B } \stopalternate \dorecurse{10}{A } \stopalternate test \par test \startalternate[text={e=mc^2}]!$e=mc^2$\stopalternate\par test \alternate{e=mc^2}{copy:}\nbsp$e=mc^2$\par which cheats on cut and paste (if you know where to click). (It actually will replace something more low level which is probably not used anyway.)

issue with doublesided layer
by Pablo Rodriguez 19 Jan '21

19 Jan '21

Dear list, I have the following sample: \definelayer[layer] [doublesided=yes] \setlayer[layer] {layer} \setupbackgrounds[text] [background={layer}] \starttext \null \stoptext Simply defining a doublesided layer breaks compilation in LMTX. It works fine with MkIV. I’m using current latest from 2021.01.18 18:19. Am I missing something or is this something that needs a fix in LMTX? Many thanks for your help, Pablo -- http://www.ousia.tk

running head for TOC
by jbf 19 Jan '21

19 Jan '21

I have a very long Table of Contents (runs across five pages) and the author would like the running head on recto pages for this to be 'Table of Contents'. I am using the following to create the TOC head: \definehead [tochead] [title] \starttochead[title={Table of Contents}] \setupheader[state=start] \placecombinedlist[content] \stoptochead And I use the following to set up the headertexts for the book as a whole: \setupheadertexts [{\hfill\getmarking[chapter]\hfill}][] %recto pages [{\hfill\documentvariable{metadata:title}\hfill}][] %verso pages The problem is that I am unable to get 'Table of Contents' as a running head for the two recto pages where I need it. I realise I need to get 'tochead' recognised somehow for this. If I set up a separate \setupheadertexts [{\hfill\getmarking[tochead]\hfill}][] then I end up with 'Table of Contents as the running head on all recto pages, which I don't want. Can anyone suggest how can I get 'Table of Contents' as the running head just for the two recto pages of a five page TOC? Julian

demo-symbols not working with LMTX
by Jairo A. del Rio 19 Jan '21

19 Jan '21

Hi, list. I was looking for information about fonts in ConTeXt defined using MetaPost and I found demo-symbols.tex for an Unicode (?) character. However, it doesn't work. While LMTX just doesn't print the symbol, MkIV complains from the Lua side. Has something changed? Jairo

3 questions about xtables after reading manuals
by Andres Conrado Montoya 18 Jan '21

18 Jan '21

I've been trying out xtables and reading the manual, some things I can't find how to do (or if it's possible on xtables): 1. How to align whole columns. It seems I have to add [align=middle] to each cell I want to have centered in a raggedright aligned table. In tabulate you can use [|l|c|] to do this, is it possible in xtables? Seems weird if it's not. Or did I miss something? 2. I know how to use [option=stretch] to fill the textwidth, but can I make specific columns "tight", so they don't get stretched beyond their content? 3. When I use [option=tight] sometimes columns are narrowed so much as to break a line of 4 or 5 words. MWE: %%%%%%%%%%%%%%%%% \startplacetable[location=none] %\startxtable[align={middle,lohi},option=tight] % This makes the first column too narrow. Lines are not that long \startxtable[align={middle,lohi}] \startxtablehead[head] \startxrow \startxcell[align=right] \strong{Concepto}\crlf\small{Cifras en miles de pesos} \stopxcell \startxcell \strong{Dato} \stopxcell \stopxrow \stopxtablehead \startxtablebody[body] \startxrow \startxcell[align=right] Bono \stopxcell \startxcell Ordinario \stopxcell \stopxrow \startxrow \startxcell[align=right] Valor nominal \stopxcell \startxcell \$100\,000 \stopxcell \stopxrow \startxrow \startxcell[align=right] Tasa cupón - periodicidad anual \stopxcell \startxcell 12,50\,\letterpercent{} \stopxcell \stopxrow \startxrow \startxcell[align=right] Cupón \stopxcell \startxcell \$12\,500 \stopxcell \stopxrow \startxrow \startxcell[align=right] Vencimiento en años \stopxcell \startxcell 5 \stopxcell \stopxrow \startxrow \startxcell[align=right] Tasa de negociación (tasa de mercado) \stopxcell \startxcell 12,50\,\letterpercent{} \stopxcell \stopxrow \startxrow \startxcell[align=right] Precio de venta \stopxcell \startxcell \$100\,000 \stopxcell \stopxrow \startxrow \startxcell[align=right] Costos de transacción/ precio de venta \stopxcell \startxcell 0 \stopxcell \stopxrow \startxrow \startxcell[align=right] Fecha de emisión \stopxcell \startxcell 30-mar-X6 \stopxcell \stopxrow \stopxtablebody \stopxtable \stopplacetable %%%%%%%%%%%%%%%%%%%%%%%%%%%% Can I make this table to be "tight" but only so much as to allow "short lines" (i.e: lines that don't make the table go wider than textwidth). I can do it with manual width, but wondering if it's possible.

LMTX isn't typesetting math correctly with Pagella
by Jack Hill 18 Jan '21

18 Jan '21

Hi, I've been having some trouble with ConTeXt not typesetting math correctly when using the Pagella font (I do not know if the same issue occurs with other fonts as I haven't tested them). If I compile with LMTX, the spacing between letters becomes very small so that when I type "|f|", for example, the second "|" intersects the f and looks rather ugly. However, compiling with the --luatex switch fixes these issues and the math looks nice again. Can anybody else replicate this issue, and does anybody know why it is happening? This the code I used to test: |\setupbodyfont[pagella] \starttext \startformula |f| = \sqrt{\int_0^1 |f(t)|^2 \text{d}t} \stopformula \stoptext ||| Jack ||
