Dear Huseyin, Thank you. It works well. And, I didn’t see any side effect either. Thanks again. Best regards, Dalyoung

font-ocl.lua:76: attempt to call a nil value (field 'register')
by Ulrike Fischer 22 Nov '18

22 Nov '18

I tried to register a demo colorpalette: \starttext \directlua{fonts.handlers.otf.registerpalette("demo", { { g=1 }, %accents { b=1 }, %06dd { r=0.5, g=0.5, b=0.5 }, %unused? { g = 0.5, b=0, r=1 }, } )} blub \stoptext and got the error font-ocl.lua:76: attempt to call a nil value (field 'register') (I wanted to test the coloring of https://github.com/alif-type/amiri/blob/master/AmiriQuranColored.ttf, Khaled wrote that "is that [the code] uses the last palette color for layers using paletteIndex 0xFFFF (special value that means use text color)." and that local default = colorvalues[#colorvalues] font-ocl.lua is faulty) -- Ulrike Fischer http://www.troubleshooting-tex.de/

You can change the alignment of the text in the table with the align-key, e.g. \startxrow [align=normal]. > One last question: could you have space before and after the frames? > Something like that > > before = ... > after = ... To get a blank line before and after the table you have to add \blank to the setups block e.g. \startsetups [userdata:purecode] \blank \startembeddedxtable ... \stopembeddedxtable \blank \stopsetups Wolfgang

debug.getinfo

Hello, the function 'debug.getinfo' was removed? The following code: ---- \startluacode print(debug.getinfo) \stopluacode \starttext A \cldcontext{tostring(debug.getinfo)} \stoptext ---- gives/prints 'nil'. IIRC, the function was non-nil some weeks ago... Best regards, Lukas -- Ing.

How to adjust the sistance between a letter and subscript
by Huseyin Özoguz 22 Nov '18

22 Nov '18

Hi Jeong, you can always adjust the space between characters like this: \startformula T_X \quad {\cal T}{\hskip-1mm}_X \quad T_Y \quad {\cal T}{\hskip-1mm}_Y \stopformula I am not sure about side effects, but seems to work fine at least in this example.

How to adjust the sistance between a letter and subscript
by Jeong Dal 22 Nov '18

22 Nov '18

Hi, In the following example, the distance between a letter ${\cal T}$ and its subscript is too big. It is not an error, but it looks a little bit strange. How to reduce it for a good looking? Thank you. Best regards, Dalyoung ***** \starttext Compare the distance between a letter and its subscript of the following example. \startformula T_X \quad {\cal T}_X \quad T_Y \quad {\cal T}_Y \stopformula \stoptext *****

A ConTeXt Guide in Italian
by Tommaso Gordini 21 Nov '18

21 Nov '18

Hello everyone! This is my first message here. I'm trying to write a ConTeXt guide in Italian. The LaTeX *tcolorbox* package defines an environment dedicated to LaTeX examples: above (or on the left) the source is written, and below (or on the right) the typeset result. Is there something similar for ConTeXt? Does it make sense, in your opinion, to showing examples of source code with the related outputs in this way? Thanks in advance for any advice on this aspect of the guide and for any suggestions. Tommy

Colormanagement
by Jan U. Hasecke 21 Nov '18

Hi all, I defined some colors with \definecolor like this: \definecolor [myblue] [r=0.000, g=0.314, b=0.580, c=0.98, m=0.67, y=0.03, k=0.12] \startnotmode[print] \setupcolors[cmyk=no,rgb=yes] \stopnotmode \startmode[print] \setupcolors[cmyk=yes,rgb=no] \setupbackend[ format=PDF/X-3:2003, intent={ISO Coated v2 300\letterpercent\space (ECI)}, ] \stopmode When I use "context" or "context --mode=print" everything works as expected. But! I have SVG icons I want to use in the document. They contain the above defined rgb colors. When I use --mode=print I get different colors for the SVG icons. So context converts the SVG files to PDFs but does not change the colors accordingly to CMYK. What are my options? Do I miss something? 1. Let the designer produce icons in pdf with the given cmyk colors. 2. Don't use cmyk colors at all. In fact on my home printer the printed rgb colors look brighter than the cmyk colors. This might change in the print shop when they print with the right color profile, but it makes me nervous. juh

issues with optical bounds
by Pablo Rodriguez 19 Nov '18

19 Nov '18

Hi Hans, many thanks for having released the new beta. I experience opposite results with opbd. The first sample is: \definefontfeature[default][default][protrusion=quality, opbd=yes] \definefontfamily[mainface][rm][Linux Libertine O] \setupbodyfont[mainface, 300pt] \setuppagenumbering[location=] \setupalign[hanging] \showframe \starttext W \stoptext Although the value for that lfbd is only -29, the W is moved too much from its original position. The second sample is (font attached at https://mailman.ntg.nl/pipermail/ntg-context/2018/092527.html) \showframe \definefontfeature[default][default][protrusion=quality, opbd=yes] \definefontfamily[mainface][rm][TestOPBD] \setupbodyfont[mainface, 60pt] \setupalign[hanging] \starttext Ἠ\\ Ἠ\hfill Ἠ\\ Ἦ\hfill ὩὩ\\ ἯἯ\hfill ὩὩ \stoptext Here the changes are tiny. The right values are used in the image at https://github.com/wspr/fontspec/issues/282#issuecomment-287155442. Could you check it? Many thanks for your help, Pablo -- http://www.ousia.tk

align=end not working
by Aditya Mahajan 18 Nov '18

18 Nov '18

Hi, According to an old thread (https://mailman.ntg.nl/pipermail/ntg-context/2016/085877.html) the option `align=end` should align the last line to be flush right. However, that is not working. The example from that thread: \starttext \showframe \showboxes \setupalign[end] \dostepwiserecurse{5}{8}{1}{ \hsize #1cm What does happen with a short paragraph?\par } \stoptext gives the attached pdf. Thanks, Aditya
