small lmtx update
by Hans Hagen 02 Feb '21

02 Feb '21

Hi, In the perspective of fancyfying context I made an alternative rendering for missing glyphs (and in the process also made the visualization italic and bold aware which is of course feature creepifying). \replacemissingcharacters \startbuffer \startlines[before=,after=] \strut {\tf test \char 12345\ test \char 12346\ test} \strut {\bf test \char 12345\ test \char 12346\ test} \strut {\it test \char 12345\ test \char 12346\ test} \strut {\bi test \char 12345\ test \char 12346\ test} \strut {test ὀ ρ φ α ν ῖ ο ς test} \stoplines \stopbuffer \starttext \startTEXpage[offset=2pt,strut=no] \getbuffer \switchtobodyfont[pagella] \getbuffer \switchtobodyfont[dejavu] \getbuffer \stopTEXpage \stoptext This is dedicated to Jano who wants to be able to search and these are proper glyphs (so one can search, assuming a sane viewer). It also fits the "new mechanisms should reduce code" bill, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

lmtx-20210118 | Corruption with rotated floats
by Richard Mahoney 01 Feb '21

01 Feb '21

List members, I've found that recent versions of LMTX seem to have broken table and figure floats using rotation. Lmtx-20210118 with for example: \placetable[here,90] results in the trashing of all subsequent body text in the PDF. This can be corrected with something such as: \placetable[here] ... \framed[orientation=90] (although one looses the ability to rotate the title of the table). The last really stable version of LMTX, which I'm finding that I'm constantly returning to as my default, is lmtx-20200920. This error has been occurring for some time now, and unfortunately, while I would like to keep up the recent releases of LMTX, it is essential that I should be able to rotate tables and images. Does anyone know of a fix.

font fallback hook (alphabet suspects)
by Jano Kula 01 Feb '21

01 Feb '21

Hello to everybody! Warning: 50 % of Greek glyphs in MWE, so they might be randomized :) Is there any hook in the font fallback? There are some Greek, Hebrew, etc. words used in the text. While proofreading, the editor would like to check these words separately (glyphs from different alphabets, unusual symbols, ...), so I'd like to typeset the warning (margin note), where these words are located. To avoid usual markup \greek{ὀρφανῖος} it could be useful to typeset a margin note whenever the defined fallback is called. The unfamiliar symbols could be in the main font and no fallback would be called then (one can still define the fallback with the main font as in the MWE, bold used for the illustration), but you might have a better ideas how to point out these suspects. The margin note is ment for searching PDF where one cannot search for color (basic viewer), which could be the other approach (also visible in print). I think, the color could be achieved with finalizers. One should also think of hyphenation and l2r/r2l direction, so in the end the usual approach might be the best way. You might use other approaches, how to deal with suspects of this type. Below the MWE for font fallbacks with distribution fonts. Not critical, just looking for ideas. Thank you, Jano \definefontfallback[Fallback] [file:DejaVuSerif-Bold.ttf] [0x0370-0x03FF] [force=yes,rscale=1] \definefontfallback[Fallback] [file:DejaVuSerif-Bold.ttf] [0x01F40,0x01FD6] [force=yes,rscale=1] \starttypescriptcollection[DejaVu] \starttypescript[serif] [DejaVu] [name] \definefontsynonym[Serif] [file:DejaVuSerif.ttf] [fallbacks=Fallback] \stoptypescript \starttypescript[DejaVu] \definetypeface[DejaVu][rm][serif] [DejaVu][default] \stoptypescript \stoptypescriptcollection \setupbodyfont[DejaVu] \starttext from ὀρφανῖος, thus \stoptext

code 139
by Thomas A. Schmitz 29 Jan '21

29 Jan '21

Hi all, a complex file with a metafun background does not compile anymore with lmtx. It compiles fine with mkiv. Compilation breaks off after 10 pages (maybe that's significant) with this message: pages > flushing realpage 10, userpage 10, subpage 10 mtx-context | fatal error: return code: 139 What is code: 139? Where should I start looking for the culprit? All best Thomas

Also, how would I go about setting the origin on the right side? Kind regards, Stefan

understanding \startTEXpage
by Peter Münster 28 Jan '21

28 Jan '21

Hi, According to https://wiki.contextgarden.net/Command/startTEXpage it "starts a page that fits its contents exactly". But it seems, that part of the content is cropped here: \startTEXpage X \hskip20cm X \stopTEXpage No problem with 10cm instead of 20cm... Is this a bug or expected behaviour? TIA, -- Peter
