Luatex 1.08.0 announcement
by luigi scarso 28 Oct '19

28 Oct '19

============================================================== LuaTeX 1.08 2018-08-28 ============================================================== (1) This release is a prelude to 1.10, the next stable iteration of LuaTeX after version 1.00. (2) Lua 5.3 is now considered to be default and we might use 5.4 in version 1.10. There are no real functional changed expected. You still need to rename the binary for 5.3! (3) Binary mode is no longer available in MPlib but it is still available in stand alone MetaPost. This simplifies compilation and reduces dependencies. (4) The dependency on Poppler for pdf image inclusion has been removed. We now use a small dedicated library written by Pawel Jakowski. We no longer need c++ compilers. We're in the process of making it behave well on all platforms. It has been tested on intel platforms. (5) We know that there can be some (alignment) issues with the arm platform but these are looked into. Therefore, later this year we will release 1.09. Version 1.10 is planned for TeXlive. We hope that ffi works ok on intel and arm platforms at that point. (6) There have been some extensions to the Lua libraries and some callbacks have been added. Also, a few new primitives have been introduced. The documentation mentions the stable extensions. (7) There are the usual bug fixes and cleanups but there have been no real fundamental changes in the API. The LuaTeX team

sound embedding with APlayer.swf and APlayer9.swf
by Pablo Rodriguez 16 Oct '19

16 Oct '19

Hi Hans, I wonder whether it would be possible to add these modified files to ConTeXt. These are needed to: 1. Deploy another SWF player. 2. Be able to stop the sound with a script, instead of being stopped when leaving the page. 3. Add other FlashVars to the SWF player. I don’t know whether this is the best approach. But I don’t see other way to configure these things. Many thanks for your help, Pablo -- http://www.ousia.tk

Font structure
by Tomas Hala 11 Oct '19

11 Oct '19

Hi all, today I downloaded current ConTeXt minimals from the garden and watched OTF and TTF fonts. I would like to ask why IBMPlex big font family is stored directly in the font "root" directory context/v201910111339/tex/texmf/fonts/opentype while all other families are arranged in their own subdirectories. I guess IBMPlex could follow them by the same way. Would it be possible? Best wishes, Tomáš

\doiftext and fallback fonts
by Wolfgang Schuster 08 Oct '19

08 Oct '19

Hi Hans, the \doiftext(else) command gives a wrong result when the checked character comes from a fallback font. \definefontfallback [testfallback] [file:dejavuserif] [greekandcoptic] \definefontsynonym [FallbackTest] [file:lmroman10-regular] [fallbacks=testfallback] \starttext \definedfont[FallbackTest] a α % does the fallback work? \doiftextelse{a}{YES}{NO} \doiftextelse{α}{YES}{NO} \stoptext As a result of this mechanism which use this check like the number renderer in the section command produce wrong output (missing number in the section title). \setuphead [section] [conversion=g] \definefallbackfamily [mainface] [rm] [DejaVu Serif] [range=greekandcoptic] \definefontfamily [mainface] [rm] [Latin Modern Roman] \definefontfamily [mainface] [mm] [Latin Modern Math] \setupbodyfont [mainface] \starttext \placecontent \section{wow} \stoptext Wolfgang

Typo in generic fontloader code for SVG
by Marcel Fabian Krüger 11 Sep '19

11 Sep '19

Hi, in font-ocl.lua, inkscape is called to convert SVG table entries to PDF. This also has a "poor mans variant for generic" around line 464 which is probably supposed to call io.popen, but calls io.open instead. Of course this breaks the conversion and leads to the creation of a weird file. (See https://github.com/latex3/luaotfload/issues/96 for details) Maybe this can be fixed to use `io.popen`? There is also a harder to fix issue: Currently the code tries to do the SVG to PDF conversion when caching the font. Especially when shell-escape is disabled, this fails. Now the problem is that in this case rerunning the commands with shell-escape enabled doesn't help because the (empty) cached entries are used. Could you add some logic to try to recreate the cache if the existing PDF cache for a font is empty? Best regards, Marcel

Re: [dev-context] [NTG-context] Side figure bug in mkiv?
by Taco Hoekwater 19 Jul '19

Hi, While at this topic: I am currently processing streaming XML and I need a way to switch to a font alternative without gobbling up following whitespace. With \bf in plain TeX, I would do this: {\bf{} bla bla} but with \bold (that I am told I should use instead), that doesn't work because the empty group becomes the argument. I now have {\bold\relax{} bla bla} but that is quite silly. Is there some official command to ‘fix' this issue? > On 19 Jul 2019, at 13:52, Wolfgang Schuster <wolfgang.schuster.lists(a)gmail.com> wrote: > > Henri Menke schrieb am 18.07.2019 um 23:29: >> For what it's worth, the MKIV way to switch to bold face is \bold{text} >> instead of {\bf text} but it also doesn't fix your problem because >> neither of the two start a new paragraph before the first letter and >> therefore \the\everypar is still inside a group. > The normal switch to use bold style is \bf and \bold{...} (or {\bold ...}) is only a alternative > switch which uses \bf to change the font.

type key in \setupattachment
by Pablo Rodriguez 19 Jun '19

19 Jun '19

Hi Wolfgang, this comes from a previous message from this mailing list (https://mailman.ntg.nl/pipermail/dev-context/2019/003574.html) which I needed a long while to understand 😅. Would it be possible that the \setupattachment command has a "type" key to specify its MIME type? (Default should be "application/octet-stream" [or so it seems].) This is required to add the value to the /Subtype entry in the /Embeddedfile dictionary (https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#name…) This is optional information in PDF-1.7, but required in PDF/A-2. Many thanks for your help, Pablo -- http://www.ousia.tk

Hi, the blocks.select function needs a check on line 122 for the mtags variable which can be nil. function blocks.select(state,name,tag,criterium) criterium = criterium or "text" if find(tag,"=",1,true) then tag = "" end local names = settings_to_set(name) local all = tag == "" local tags = not all and settings_to_set(tag) local hide = state == "process" local result = lists.filter { names = "all", criterium = criterium, number = sections.numberatdepth(criterium), -- not needed collected = collected, } for i=1,#result do local ri = result[i] local metadata = ri.metadata if names[metadata.name] then if all then printblock(ri.index,name,ri.data,hide) else local mtags = metadata.tags for tag, sta in next, tags do - if mtags[tag] then + if mtags and mtags[tag] then printblock(ri.index,name,ri.data,hide) break end end end end end end Wolfgang
