Dear Aditya, > You cannot use [offset=2mm] here. Just use \startuseMPgraphic{boxes}. > After remove [offset=smm], it is working well. Thank you for the solution. Best regards, Dalyoung

Dear Aditya, Thank you for your code and an explanation. > Let's assume that the last MPpage was a \startuseMPgraphic{boxes} .... \stopuseMPgraphic.

double-sided page number placement

Dear Hans, The following file: \setuplayout[location=doublesided] \setuppagenumbering[location=inmargin,alternative=doublesided] \starttext \dorecurse{20}{\input knuth } \stoptext using: > ConTeXt ver: 2021.04.21 11:39 LMTX fmt: 2021.7.11 int: english/english the left page of the double spread places the page number on the right margin of the page and in the right page it is placed on the right margin using: > ConTeXt ver: 2019.06.20 18:47 MKIV beta fmt: 2019.6.23 int: english/english the left page of the double spread places the page number on the left margin of the page and in the right page it is placed on the right margin. This is what I would like to get in LMTX as well. Am I doing something wrong here? Thanks, Charlie

weekend upload
by Hans Hagen 12 Jul '21

Hi, This weekend upload has something new for metapost animation lovers: \starttext \startuseMPgraphic{demo} stacking := 6; fill fullcircle scaled 10cm withcolor "red" ; % stacking := 3; stacking := 9; fill fullcircle scaled 10cm shifted (3cm,0) withcolor "green" ; interim stacking := 4; fill fullcircle scaled 10cm shifted (3cm,3cm) withcolor "blue" ; for i=1 upto 10 : draw fullcircle scaled (i*cm) withstacking 8 withpen pencircle scaled 1mm withcolor "gray" ; endfor ; for i=1 upto 20 : draw fullcircle scaled (i*cm/2) withstacking (if odd(i) : i else : 5 fi) withpen pencircle scaled 2mm ; endfor ; draw boundingbox currentpicture withpen pencircle scaled 1pt withstacking 0 ; currentpicture := currentpicture xsized 15mm; \stopuseMPgraphic \setupMPvariables[demo] \startTEXpage \vskip1ex \hbox{\space\dorecurse{10}{\useMPgraphic{demo}{list={0,#1}}\space}} \vskip1ex \nointerlineskip \hbox{\space\dorecurse{10}{\useMPgraphic{demo}{list={0,1-#1}}\space}} \vskip1ex \stopTEXpage \stoptext I have some more ideas but want to approach it stepwise. It bpils down to the fact that one can put stuff on different 'layers' and optionally flush these (by default all are flushed but the stackling order is honored). An advantage is that one doesn't have to set up a graphic in order (read: save pictures, flush them later on) and it is actually a rather cheap extension in terms of runtime and overhead. Although I could emulate it in mkiv, it is currently an LMTX only feature. The (optional) list accepts the usual {1,2,5,7-9} kind of specification.

LMTX crashes with source
by Pablo Rodriguez 11 Jul '21

11 Jul '21

Dear list, I have the following source: \definefontfamily [malayalam] [rm] [RIT Rachana] %~ [features=malayalam-two] \setupbodyfont [malayalam] \starttext \startTEXpage \tf അദ്ധ്യായം\\ \em അദ്ധ്യായം\\ \em\bf അദ്ധ്യായം\\ \em അദ്ധ്യായം \stopTEXpage \stoptext Using latest from 2021.07.06 18:49 and the following fonts: http://rachana.org.in/downloads/RIT-Rachana-Regular.ttf http://rachana.org.in/downloads/RIT-Rachana-Italic.ttf http://rachana.org.in/downloads/RIT-Rachana-Bold.ttf http://rachana.org.in/downloads/RIT-Rachana-BoldItalic.ttf I get a crash when using LMTX, but not with MkIV (in both Windows and Linux). I’m afraid it might be a bug. Could anyone confirm the issue? Many thanks for your help, Pablo -- http://www.ousia.tk

Ampersand in \unprotect fails in LMTX
by Marco Patzer 09 Jul '21

09 Jul '21

Hi! the following example compiles with MkIV but fails in LMTX: \unprotect \setupinteraction [\c!author={Foo & Bar}] %% {Foo \& Bar} works for MkIV and LMTX \protect \starttext\null\stoptext LMTX: 1 \unprotect 2 \setupinteraction 3 [\c!author={Foo & Bar}] 4 >> \protect 5 6 \starttext\null\stoptext 7 I can't figure out why you would want to use a tab mark here. If some right brace up above has ended a previous alignment prematurely, you're probably due for more error messages. mtx-context | fatal error: return code: 256 As \& works for MkIV as well as LMTX, there's an easy workaround. But maybe this isn't intended behaviour and needs checking. ConTeXt ver: 2021.07.06 18:49 LMTX Marco

Initial caps with short paragraph
by Thangalin 09 Jul '21

09 Jul '21

This has come up before on the mailing list, but I was wondering if LMTX has a more elegant solution than using a transparent/invisible capture of the drop-cap. Consider: \setupinitial[n=2, style=\tfd, location=text]\setuphead[chapter][after={\placeinitial}] \starttext \chapter Hello world! \input ward\stoptext The output shows that the second paragraph is not indented beyond the bounding box of the drop-cap, resulting in an overlap. This isn't a problem when the first paragraph spans two or more lines. Any ideas for how to resolve this without changing the content? Thank you!

font feature
by Thomas A. Schmitz 09 Jul '21

09 Jul '21

Hi all, is it possible to subtract a featureset that has been applied to a fontfamily? MWE: \definefontfeature [f:frac] [frac=yes,onum=no,pnum=no] \definefontfeature [f:onum] [onum=yes,pnum=yes] \definefontfamily [test] [serif] [AntykwaTorunska] [features=f:onum] \definefontfamily [test] [sans] [Myriad Pro] \definefontfamily [test] [mono] [DejaVu Sans Mono] \definefontfamily [test] [math] [Xits Math] \setupbodyfont[test,12pt] \starttext Mozarts erster Satz ist ein {\subtractfeature[f:test]\addfeature[f:frac]4/4}-Takt, Beethoven wählt einen Dreiertakt, Mozarts Romanze ist ein 3/8-Takt, Beethoven wählt einen 2/4, Mozarts Rondo ist eine Gavotte im 2/2-Takt, Beethoven schreibt ein Jagdrondo im 6/8-Takt. \stoptext If I comment out the part [features=f:onum], I get the fractions that I'm looking for, but it seems that I can't get the same effect with \subtractfeature and \addfeature. I'm confused... Thanks and all best Thomas

[OT] TeXShop v4.66 adds support for new ConTeXt's syncing method
by Nicola 09 Jul '21

09 Jul '21

For those who are interested, the latest TeXShop release provides support for ConTeXt's own syncing method (by invoking mtxrun --script synctex). This supersedes the old syncing method based on Laurens' SyncTeX, which should not be used any more. I have brought TeXShop's page in the wiki up to date (I haven't touched what are currently §1.4 and §1.5), with instructions to get synchronisation to work: https://wiki.contextgarden.net/TeXShop Make sure to read it carefully! I have tested the feature for some time now, and I'd say that it works pretty well (with some caveats, which I have annotated in the wiki). I take the opportunity to thank Hans for being so responsive with the changes in mtxrun necessary to provide this feature, and for patiently bear with my sometimes unclear requests or feedback. Kudos also to Richard Koch (TeXShop's author) for his relentless support of the macOS TeX community and, in this case, of the ConTeXt community! Happy ConTeXt'ing! Nicola
