internal mptopdf conversion fails on older mps file (using MkIV, beta 2013.12.26)

The MkIV internal mptopdf converter fails on the following minimal example. Here is the tex: ------- cut test2.tex here ------------- \enabletrackers[graphics.conversion,graphics.inclusion,fonts.mapfiles,fonts.loading,fonts.missing,fonts.mapping] \starttext \externalfigure[fig.1][frame=on] \blank \externalfigure[fig-1.pdf][frame=on] \stoptext ------- cut test2.tex here ------------- And here is the figure, which was produced with mpost 0.993 (and also converted to fig-1.pdf using the 'mptopdf' command): -------- cut fig.1 here ------------ %!PS-Adobe-3.0 EPSF-3.0 %%BoundingBox: 0 0 10 10 %%HiResBoundingBox: 0 0 9.96262 9.96262 %%Creator: MetaPost 0.993 %%CreationDate: 2009.10.21:1318 %%Pages: 1 %%BeginProlog /bd{bind def}bind def /hlw{0 dtransform exch truncate exch idtransform pop setlinewidth}bd /vlw{0 exch dtransform truncate idtransform setlinewidth pop}bd /l{lineto}bd/r{rlineto}bd/c{curveto}bd/m{moveto}bd/p{closepath}bd/n{newpath}bd /C{setcmykcolor}bd/G{setgray}bd/R{setrgbcolor}bd/lj{setlinejoin}bd/ml{setmiterlimit}bd /lc{setlinecap}bd/S{stroke}bd/F{fill}bd/q{gsave}bd/Q{grestore}bd/s{scale}bd/t{concat}bd /sd{setdash}bd/rd{[] 0 setdash}bd/P{showpage}bd/B{q F Q}bd/W{clip}bd %%EndProlog %%Page: 1 1 0.7 G n 0 0 m 0 9.96262 l 9.96262 4.98131 l p F P %%EOF -------- cut fig.1 here ------------ Running it through MkIV with the 2013.12.26 beta (or the stable context) produces an empty frame for the inclusion of fig.1, but the correct triangle for the inclusion of fig-1.pdf.

current

Hi, I uploaded a current. As we're now moving forward to luatex 0.80 (with currently 0.78 as beta) the current reflects the < 0.78 state of affairs. From now on betas might use new luatex functionality so best update to 0.78+ (unless i mess up too much older luatex's will work ok too). The upcoming months the redone bibtex support will also en dup in the code base (given that it passes Thomas and Allan quality assessments). The minimals are now windows 32 and windows 64 aware. There are two installation zips on the garden. If you're on 64 bit but still run 32 bit, you can best - wipe context/bin (where the installer files live) - unzip the new installer zip - remove the status file - remove context/tex/texmf-mswin (the new binaries are in context/tex/texmf-win64) and run the status-update script. Or just install the while lot fresh (which is fast anyway), and keep the old trees for a while. Thanks to Akira for supporting 64 bit and keeping up so fast, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Hi, The current windows version on the garden is broken, so don't update for a few days. The binaries will be fixed asap (but these are not the easiest days for this kind of things).

workarounds required for book layouts.
by john Culleton 31 Dec '13

31 Dec '13

For print books the half-title page is backed by a blank page but the full title page is backed by the copyright page. The first page of the bodymatter (chapter 1 in most cases) is recto faced by a blank verso. There are workarounds that obtain this layout. First \standardmakeup command must be modified thus: \setupmakeup[standard][page=yes, doublesided=no] Then to get a blank page after the half title We must insert a dummy page thus: \startstandardmakeup \null \stopstandardmakeup These two moves put a blank page after the half title but forbid it thereafter. The blank page after \startbodymatter, after \startbackmatter and after \startappendix is provided by: \setupsectionblock[frontpart][page=] \setupsectionblock[bodypart] [page=] \setupsectionblock[backpart] [page=] \setupsectionblock[appendix] [page=] This combination of workarounds gets the job done. There may be other combinations that do it as well. My suggestion is that all the above setup commands should be built into context. It takes some exploration of the mailing list to ferret out these layout techniques. I have already added them to my boilerplate macros.tex file that I insert in every book layout file. But others have to discover these techniques afresh when they start using Context for books. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html

Comfortaa font and ligatures
by Flavien Lambert 30 Dec '13

30 Dec '13

Dear all, I would like to use the comfortaa font available at http://www.dafont.com/comfortaa.font. I managed - maybe in a wrong way - to do it through the following example: \definefontfeature[comfortaa][mode=node,kern=yes,liga=yes,dlig=yes] \starttypescriptcollection[comfortaa] \starttypescript[sans][comfortaa][name] \setups[font:fallback:sans] \definefontsynonym[Sans][name:comfortaa][features=default] \stoptypescript \starttypescript[comfortaa] \definetypeface[\typescriptone][ss][sans][comfortaa][default] \stoptypescript \stoptypescriptcollection \setupbodyfont[comfortaa] \starttext fl fi \stoptext Unfortunately, there are no ligatures whereas the snapshots given by the author show some of them like fi and fl. Did I use the correct script? Best regards, Flavien.

[metapost] troubles with labels
by Pol Stra 29 Dec '13

29 Dec '13

Dear all, with this minimalist content of metapost file: ``` beginfig(1); dotlabel.ulft("A", origin); endfig; end. ``` And this conteXt file: ``` \starttext \startMPrun input mymp.mp; \stopMPrun \externalfigure[mprun.21][width=5cm] \stoptext ``` The resulting pdf file contains no figure. But this conteXt file works: ``` \starttext \startMPcode dotlabel.ulft("A", origin); \stopMPcode \stoptext ``` As with any metapostfile which does not contain labels. But as soon as there is label, their is no figure. Two last things: if I compile the metapost file with standalone metapost, I can include the resulting file as an external figure. But if I put a label "A'", while with displaying figure with a viewer it is ok, when included in a conteXt file, I only obtain "A" label. Also, if I try to change the font in the metapost file (for example defaultfont:="pplr8r";) it does not work in conteXt. Do you have an explanation or workaround? Thank you

boxedcolumns weirdness
by H. van der Meer 29 Dec '13

29 Dec '13

I am typesetting a series of items with boxedcolumns enclose in a framedtext: \startframedtext[width=\makeupwidth,offset=0pt,frame=off,align=tolerant] \startboxedcolumns[n=2,separator=rule] Occasionally it happens that material at the end of the first column is not typeset. It occurs haphazardly in a large (more than 300) series of items. Depending on the length of the first columns material (I introduced extra space with \crlf, \blank, \blank[dimension]) other items exhibit the effect. Because of this haphazard character, the large data set and the fact that I could not isolate it in a few items, I regrettably do not have a minimal example. Thus I can only signal it here, in case others encounter it too. Or in case the person maintaining this code happens to spot the problem from the observation alone.

Centering the last line in combination subcaptions
by Jan Tosovsky 27 Dec '13

27 Dec '13

Hello Everyone, I try to fill the entire page with two images with their captions. The final page should be floating, keeping both images together and not containing any other text. I found this solution. It work fine for short captions / wide images. \starttext test \startplacefigure[location=page, number=no, title={}] %\setupcombinations[align={hz, hanging}] %\setuptolerance[strict] {\startcombination[1*2] {\externalfigure[cow]} {\input{ward}} {\externalfigure[cow]} {\input{ward}} \stopcombination} \stopplacefigure \stoptext If captions are long and the image narrow, they are typeset on multiple lines. Default centering produces the ragged column - both not very nice and difficult to read. When the alignment is set to hanging, it looks better except the last line which is not centered. Is there any settings for centering the last line? Can the 'column' width be somehow extended to e.g. 80% of text width? If not via the 'combination', are there any better alternatives for my use case? Any hint is appreciated. Thanks, Jan
