Asymptote and Context
by Context NTG 19 Apr '18

19 Apr '18

I am running context minimals and Asymptote on Windows.This example used to work in the past, but it seems to have stopped working. Is there anything that has changed? \usemodule[filter] \defineexternalfilter [ASY] [filtercommand={asy -tex "context" -outformat pdf -outname \externalfilteroutputfile}, output=\externalfilterbasefile.pdf, cache=yes, readcommand=\ReadImage,] \define[1]\ReadImage{\externalfigure[#1]} \starttext Testing if we can include an asymptote image \startplacefigure[location={here}, title={An Asymptote figure}] \startASY unitsize(1cm); draw((-.1,0) -- (2,0), arrow=Arrow(TeXHead)); draw((0,-.1) -- (0,2), arrow=Arrow(TeXHead)); draw((0,0) .. (1,1) .. (2,sqrt(2))); \stopASY \stopplacefigure \stoptext

Hi, I found \definecolumnset in the wiki not in the setup-en.pdf. I’ll test it again. Thank you for reading. Best regards, Dalyoung

numberstopper in \setupcaptions
by Alan Braslau 19 Apr '18

19 Apr '18

Hello list members, I am not sure how to achieve the following functionality: Using \startplacefigure, I would like to place a number stopper *only* when the caption text is non-empty, i.e. Figure 1 Figure 2: A cow This would be achieved through \setupcaption [figure] using numberstopper= I believe (with perhaps a filter), but I am not sure of exactly how to do this, especially how to do this most elegantly. Thank you Alan

\startplacetable in \startcolumnset
by Jeong Dal 19 Apr '18

Hi, I used the following exam format well which was set by the help of Wolfgang long time ago. Recently I got a strange output when I used \startplacetable or \placetable in the \startcolumnset … \stopcolumnset. There is a strange number first and table in the next column. The output is OK if I comment out either \startcolumnset or \placetable. Is “\definecolumnset, \startcolumnset” still a good command? I couldn’t find it in the list of commands. Thank you for reading. Best regards, Dalyoung %%%%%%%%%%%%% \startuseMPgraphic{verticalrule} if CurrentColumn < NOfColumns : draw leftboundary OverlayBox;% shifted (-1mm,0); draw rightboundary OverlayBox shifted (4mm,0); draw rightboundary OverlayBox shifted (TextWidth+6mm,0); draw bottomboundary OverlayBox shifted (1mm,0); draw bottomboundary OverlayBox shifted (TextWidth+6mm,0); setbounds currentpicture to OverlayBox enlarged 2.5mm; fi \stopuseMPgraphic \defineoverlay [verticalrule] [\useMPgraphic{verticalrule}] \definecolumnset [exam] [n=2, background=verticalrule] \starttext \startcolumnset[exam] \startcolumns[n=2, rule=on] \startitemize[n] \item Question 1.

Indeed. I should have known better. Temporary attack of brain weakness, I suppose. For those who want to see for themselves, the minimal example below will do. dr.

luatex 1.08
by Hans Hagen 19 Apr '18

19 Apr '18

Hi, We released luatex 1.08 beta which uses lua 5.3 and will be default on the garden as soon as mojca moves the bins to the right place. We don't expect many issues as we tested it for quite a while. The context current works on both 1.07 and 1.08 but of course at some point the beta might evolve towards using 1.08 features. We're now stepping up to 1.09 for ourselves and will probably release that around the ctx meeting, which then leads to 1.10 for tex live 2019.

Luatex 1.07.0 announcement
by luigi scarso 19 Apr '18

19 Apr '18

============================================================== LuaTeX 1.07 2018-01-17 ============================================================== (1) This release brings Lua 5.3 to LuaTeX. We have tested an experimental version for a few months and not encountered issues. (2) If you use Lua 5.3 you should be aware of a few changes in the language and its implementation. Numbers are now either integers or floats but are cast automatically. (3) In some cases (e.g. string.format) there is a more strict check. A float always has a decimal appended when serialized, so 1 becomes 1.0 as string. (4) We keep supporting the bit32 library on top of the new bit operators. Be aware of the fact that currently LuajitTeX does not have these operators. (5) Performance of LuaTeX with Lua 5.3 can be slightly better than with 5.2 but this really depends on your usage of Lua. In practice there should be no slowdown. (6) We are aware of possible substantial slowdown of string.format depending on the platform and compiler. This depends on Lua too and will be resolved in due time. (7) If you want to test with Lua 5.3 then have to build LuaTeX with --lua53. Because ConTeXt will switch to 5.3 after this release there will be binaries available at the ConTeXt garden. (8) The 2018 TeXlive distribution will ship with LuaTeX using Lua 5.2 but there will likely be an additional binary LuaTeX53 available. (9) From 2019 TeXlive will ship with LuaTeX and Lua 5.3 as default. We provide --lua52 as build flag for a while. By then we might be looking at Lua 5.4 already. (10) There are the usual patches and cleanups and a few small additions (mentioned in the manual) but there have been no fundamental changes in the API (apart from removing depricated and undocumented functionality).

goto reference
by Hans van der Meer 19 Apr '18

19 Apr '18

I have the following question about referencing. With \goto{typeset_the_text}[url(file://a_file_location_to_goto <file:///a_file_location_to_goto>.pdf)] I can open a pdf from inside the document that has been typeset. It would, however, be nice if I could further specify on which page of the pdf to open. Is this possible? Or is this a wish not to be fulfilled? dr. Hans van der Meer

problem with character entities in XML processing
by Hans van der Meer 19 Apr '18

19 Apr '18

The following use of character entities & aborts in ConTeXt. That is of course because the # is seen as a parameter. Changing this to &\#xxx; or &\letterhash xxx; typesets & as is, but that is not the intention, because an ampersand should appear. So, how do I proceed here? Minimal example: % test character entity failure. \startxmlsetups demo:entity \xmlsetsetup{#1}{root}{demo:entity:*} \stopxmlsetups \xmlregisterdocumentsetup{demo}{demo:entity} \startxmlsetups demo:entity:root \blank Start test:\crlf root: <amp> = "&"\crlf root: <number> = "&\letterhash 038;”\crlf % &\#038; produces the same End test\blank \stopxmlsetups \startbuffer[demo] <root></root> \stopbuffer \starttext \currentdate-\currenttime\quad\ConTeXt-version=\contextversion\blank {\bf Testing use of character entities}\blank These should produce the same result: \type{&} and \type{&}\blank \xmlprocessbuffer{demo}{demo}{}\blank \stoptext dr.
