optical bounds with hanging diacritics
by Pablo Rodriguez 27 Nov '18

27 Nov '18

Hans, I added lfbd values for GFS Didot (attached) to get hanging diacritics in Greek. The attached PDF document is the optput from the following code: \showframe \setuplayout[topspace=1cm, height=middle, footer=0cm, header=0cm] \definefontfeature[default][default] [protrusion=quality, opbd=yes, script=grek] \definefontfamily[mainface][rm][GFS Didot] \setupbodyfont[mainface, 325pt] \setupalign[hanging] \starttext Α\\Ἀ\\Α\\Ἁ\\Α\\Ἂ\\Α\\Ἃ\\Α\\Ἄ\\Α\\Ἅ\\Α\\Ἆ\\Α\\Ἇ Ἐ\\Ε\\Ἑ\\Ε\\Ἒ\\Ε\\Ἓ\\Ε\\Ἔ\\Ε\\Ἕ\\Ε Ἠ\\Η\\Ἡ\\Η\\Ἢ\\Η\\Ἣ\\Η\\Ἤ\\Η\\Ἥ\\Η\\Ἦ\\Η\\Ἧ\\Η Ἰ\\Ι\\Ἱ\\Ι\\Ἲ\\Ι\\Ἳ\\Ι\\Ἴ\\Ι\\Ἵ\\Ι\\Ἶ\\Ι\\Ἷ\\Ι Ὀ\\Ο\\Ὁ\\Ο\\Ὂ\\Ο\\Ὃ\\Ο\\Ὄ\\Ο\\Ὅ\\Ο Ρ\\Ῥ Ὑ\\Υ\\Ὓ\\Υ\\Ὕ\\Υ\\Ὗ\\Υ Ὠ\\Ω\\Ὡ\\Ω\\Ὢ\\Ω\\Ὣ\\Ω\\Ὤ\\Ω\\Ὥ\\Ω\\Ὦ\\Ω\\Ὧ\\Ω \stoptext BTW, to get pure lfbd values, I had to replace line 361 from font-imp-quality lua with: local p = d/1000 Raw lfbd and rtbd values from the font could be set with protrusion=opentype (or a similar option). I hope it is clear now why raw values from the font are needed. Many thanks for your help, Pablo -- http://www.ousia.tk

Hi everyone. The following code gives different results by commenting and decommending the indicated lines. Could it be a problem with the setups module? Thanks in advance Tommy \usemodule [setups] \starttext %\startbuffer %\framed [width=3cm,height=1cm] {testo} %\stopbuffer % %\typebuffer %\getbuffer \cmdfullsetup [setuppapersize] \stoptext

Subformula numbering
by adrien Licari 26 Nov '18

26 Nov '18

Hi everyone, I can't get cases subformula to work properly. My MWE, inspired from the wiki and the My Way "Using \startalign and friends" by Aditya Mahajan, is : \starttext\placeformula\startformula \startcases \NC x = a \NR[+] \NC y = b \NR[+] \stopcases\stopformula\stoptext This only prints (2) on the right of the whole cases system. If I use \placesubformula, the behavior remains exactly the same. It also yields the same output with live ConTeXt. The ConTeXt version I am using is 2018.01.19 13:42 Has there been a change in the behavior since the documents were written ? I asked on stackexchange, and since the document is 12 years old and the wiki consistent with it, they suggested me to ask the mailing list. Thanks in advance, -- Adrien Licari-Guillaume Professeur de Physique-Chimie MPSI et d'informatique IPT MP & PSI Lycée Jean Dautet (La Rochelle)

Which commands to use to show setups?
by Tommaso Gordini 25 Nov '18

25 Nov '18

Hello, list. In my ConTeXt guide, I need to show the syntax of ConTeXt commands. Below I paste a MWE showing the different possible commands, but I do not know if there are others. I see, however, that the result is different depending on the command used. Do you have any advice to give to me? Which of the commands in the code should I use in a guide? Or better: do they have to be used according to needs? Are there other commands of this kind? Thank you in advance Tommy \usemodule[x-setups-basics] \loadsetups[context-en] \starttext \showsetup[centerline] \showsetup[starttyping:instance] \showsetup[starttyping:instance:typing] \cmdfullsetup{section:instance} \cmdfullsetup{section:instance:chapter} \cmdfullsetup{section:instance:ownnumber:chapter} \cmdfullsetup{section:instance} \cmdfullsetup{section:instance:chapter} \cmdfullsetup{section:instance:ownnumber:chapter} \showrootvalues[head] \showinstancevalues[head][chapter] \stoptext

Hi all, I think I found another bug in xtable (or placetable). The last table in the MWE is not showing the first row (the header row). Thanks, Chris

custom environment for geographical pictures; new head or special float?
by Damien Thiriet 24 Nov '18

24 Nov '18

Hello, When creating my geography presentations, I often need to show so-called « croquis », that are outlines of maps or landscapes. A typical slide with croquis looks like this: ------------------- title ------------------- outline (a MP graphic) ------------------- key to symbols (natural table) ------------------- All this is enclosed into a makeup to reduce margins. I am now automating this and wonder what should be the best way to do it. * creating a head style at subsection level was my first thought, but on the semantical point of view, it is not the best one, since other slides are not considered as subsubsections. If I stick to this, should I use subsubsection as a default which it's derived from. * creating a float would be better, since this is a float. Would there be a way to insert automatically key to symbols under the metapost graphic? Thanks, Damien Thiriet

Completecontent has problems with chapter in table
by Huseyin Özoguz 24 Nov '18

24 Nov '18

Hello together, I have this min-example: \starttext \completecontent[criterium=all] \chapter{craigs} {\bTABLE \bTR\bTD \chapter{whatever} \eTD \eTR \eTABLE} \chapter{gooff} \completecontent[criterium=previous] \stoptext As you see, the \completecontent[criterium=previous] works fine, it lists all chapters. But the \completecontent[criterium=all] does not, only lists the first chapter. How to fix this? Thank you! Huseyin -- Huseyin Özoguz E-Mail: h.oezoguz(a)mmnetz.de

PDF/A output fails validation
by Rik Kabel 23 Nov '18

23 Nov '18

With the latest beta, PDF/A fails validation in a new way. Using the example document in the wiki <https://wiki.contextgarden.net/PDF/A>, PDF/A-1a validation fails the online validator <https://www.pdf-online.com/osa/validate.aspx> [2] with: The key MarkInfo is required but missing. The key StructTreeRoot is required but missing. The key CIDSet is required but missing. The document does not conform to the requested standard. The document contains fonts without embedded font programs or encoding information (CMAPs). The document doesn't provide appropriate logical structure information. The document does not conform to the PDF/A-1a standard. while with PDF/A-1b requested, the MarkInfo and StructTreeRoot issues are not reported. (A-2a and A-3a fail in the same was as A-1a.)
