strc-blk.lua

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

Missing indentnext check in buff-ver.mkiv
by Henri Menke 28 May '19

28 May '19

Dear devs, \typebuffer does not obey the indentnext option from \setuptyping because the corresponding checks are missing in \buff_verbatim_type_buffer and \buff_verbatim_type_buffer_indeed. I have attached a possible patch. Cheers, Henri

/AF key for attachments (in PDF/A-3)
by Pablo Rodriguez 26 May '19

26 May '19

Hi Hans, attachments in PDF/A-3 need to be related (as an array) to the document with the /AF key. I already reported this and I think that the most sensible value is to relate them to the document. That would mean to include the /AF key in the /Catalog dictionary. I think this would be the easiest way to implement and to use it. Many thanks for your help, Pablo -- http://www.ousia.tk

\lastxpos and \lastypos should behave like registers
by Henri Menke 23 May '19

23 May '19

Dear devs, The two macros \lastxpos and \lastypos should behave like registers, because that is what they are in LuaTeX. The following MWE fails with ! You can't use `the character 0' after \the \starttext \the\lastxpos \the\lastypos \stoptext A simple fix would be to wrap the macro in \numexpr like in the attached patch. Cheers, Henri

Interface fails fail to create PDF
by Wolfgang Schuster 07 May '19

07 May '19

Hi, when I add new commands, options etc. to interface files I often run context on the file itself to create a PDF to check the content but for Luametatex this doesn't work anymore. When I run ConTeXt like this context i-framed.xml I can see ConTeXt creating pages mtx-context | jobname: i-framed.xml mtx-context | ctxname: x-setups.ctx [...] pages > flushing realpage 1, userpage 1, subpage 1 pages > flushing realpage 2, userpage 2, subpage 2 pages > flushing realpage 3, userpage 3, subpage 3 pages > flushing realpage 4, userpage 4, subpage 4 [...] mkiv lua stats > runtime: 1.146 seconds, 4 processed pages, 4 shipped pages, 3.490 pages/second system | total runtime: 1.356 seconds of 1.449 seconds but i-framed.pdf is missing in the end.

utf8 chars in XML tags
by Pablo Rodriguez 04 May '19

04 May '19

Hi Hans, I wonder whether this patch could be applied to buffer-imp-xml-lua: -local name = (patterns.letter + patterns.digit + S('_-.'))^1 +local name = (patterns.letter + patterns.digit + S('_-.') + patterns.utf8two + patterns.utf8three + patterns.utf8four)^1 This would allow to have colored XML tags with utf8 chars (such as in <título>). Many thanks for your help, Pablo -- http://www.ousia.tk

attachments in PDF/A-3
by Pablo Rodriguez 22 Apr '19

22 Apr '19

Dear list, my sample to add attachments to a PDF/A-3 valid document is the following: \setuptagging[state=start] \setupbodyfont[30pt] \setupbackend [format=PDF/A-3a, intent=sRGB IEC61966-2.1, profile={sRGB.icc,default_gray.icc}, level=0] \setupcolors[pagecolormodel=auto] \setupinteraction[state=start] \starttext \startTEXpage[offset=1em] an attachment\attachment[file=xml-mkiv.pdf] \stopTEXpage \stoptext There are five reported errors when tested with the latest development version of veraPDF (http://downloads.verapdf.org/dev/verapdf-installer.zip) - Annotation should have /F value (https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…) unless their Rect key value 1 equal to value 3 and value 2 equal to value 4, or the annotation subtype is /Popup or /Link. - Although not reported, the /F value should conform these considerations: If present, the F key's Print flag bit shall be set to 1 and its Hidden, Invisible, ToggleNoView, and NoView flag bits shall be set to 0. https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an… - Annotations need an appearance dictionary (https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…) unless the same exception for the /F value apply. - The /EmbeddedFile dictionary should specify the MIME type in its /Subtype entry (https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…) - The /AFRelationship key is missing from the /Filespec dictionary (https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…) Possible values are: Source, Data, Alternative, Supplement, EncryptedPayload, FormData, Schema or Unspecified (from https://www.pdfa.org/wp-content/uploads/2018/10/PDF20_AN002-AF.pdf) - The /Filespec lacks association with the PDF document or any of its parts, such as pages (https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…) From https://www.pdfa.org/wp-content/uploads/2018/10/PDF20_AN002-AF.pdf, it seems that either the /Catalog or a /Page dictionary (there are other ones, but I would limit attachments in ConTeXt to those two [if not to the /Catalog itself only]) should contain an /AF entry with the reference to the /Filespec object(s). I assume that the value type for the /AF entry is an array of one or multiple object references. These are all the issues veraPDF finds when validating the PDF document generated from the source above. I hope it helps. Many thanks for your help, Pablo -- http://www.ousia.tk

Quoting problems in grph-con.lua
by Kevin Boulain 21 Apr '19

21 Apr '19

Hi, >From my understanding, there are some superfluous quotes in context/base/mkiv/grph-con.lua, cancelling the proper quoting done by validcommand in context/base/mkiv/util-sbx.lua. For my document, it tries to run something like (the space in the 'Google Drive' directory breaks the generation): inkscape ""[...]/Google Drive/[...].svg"" --export-dpi=600 --export-pdf=""[...]/Google Drive/[...].svg.pdf"" Applying this patch fixes the double quotes issue: local runner = sandbox.registerrunner { name = "svg to something", program = "inkscape", template = longtostring [[ - "%oldname%" + %oldname% --export-dpi=%resolution% - --export-%format%="%newname%" + --export-%format%=%newname% ]], However, it seems there are more similar quotes in the other templates of the file. mtx-context | current version: 2019.04.16 08:54 (I hope this is the proper way of reporting.) Regards.

lmtx and page injections

Hi Hans, the new luametatex release doesn't work with the \pageinjection command. The resulting pdf shows the same content on all pages, e.g. in the following example I get the first page twice. \starttext Before \pageinjection [empty] After \stoptext Wolfgang
