LMTX, mathcases and noalign
by Jean-Philippe Rey 13 Nov '20

13 Nov '20

Dear list, I am trying to switch from MKIV to LMTX. I've just found a discrepancy with the following code which puts space between two lines in a math alignment. This minimum breaking example uses \startcases, but the same problem arises with other alignment macros. \starttext \startformula \startcases \NC 1 \NC if not null \NR \noalign{\vskip2ex} \NC 0 \NC if null \NR \stopcases \stopformula \stoptext This snippet works fine with MKIV but breaks in LMTX (see attached log file). Is this a bug in LMTX or is there another way to insert space between two lines? I've already tried different other solutions, but none seems really appropriate: - \intertext produces a vertical space of at least 3 lines and I haven't been able to make it smaller; - adding an empty line (\NC \NR) produces a smaller space but I am unable to reduce its height below a minimum value (roughly a line); - adding a \vrule to the above or below line works fine but it needs some calculation depending on the content of the line.

problems with signature fields
by Pablo Rodriguez 12 Nov '20

12 Nov '20

Hans, I have the following sample: \setupinteraction[state=start] \starttext \startTEXpage[offset=1em] \definefield[x][signature] \field[x] \stopTEXpage \stoptext I can only use Acrobat to sign PDF documents with signature fields generated by ConTeXt. Other tools sign the PDF document not producing a valid signature (Acrobat cannot read or validate it). From the source, signature has two objects (copied from the sample above): 2 0 obj << /DA (/rmtf 11.9552 Tf 1.1955 Ts 0 0 0 rg 0 0 0 RG) /DV <FEFF> /F 4 /FT /Sig /Ff 0 /Kids 1 0 R /MaxLen 1024 /Q 0 /Subtype /Widget /T <FEFF0078> /V <FEFF> >> endobj 4 0 obj << /Type /Annot /DA (/rmtf 11.9552 Tf 1.1955 Ts 0 0 0 rg 0 0 0 RG) /F 4 /Parent 2 0 R /Q 0 /Subtype /Widget /Rect [ 14.033054 14.033054 70.40415 25.08072 ] >> endobj One of the tools that has issues with two objects for the signature field is the latest version (1.18) from mupdf-gl. mupdf-gl adds the signature value to the child (object 4) and not to its parent (object 2). I’m afraid this is also the same issue that AutoFirma (a e-signing tool developed by the Spanish government [https://firmaelectronica.gob.es/Home/Descargas.html] has with these signature fields. When both objects are merged in one (as Acrobat Reader does when saving a copy), both tools generate documents contaning signatures totally unproblematic to be read validated by Acrobat. I suggested merging both objects back in 2017. You told me that simplifyng this would introduce too much complexity in ConTeXt only to save some bytes. Back then, I thought it was an minor improvement. Now I realized that this two objects for signature fiels are only valid for Acrobat. I wonder whether this improvement might be also easier to make in LMTX. Would it be possible that signature fields may have only one object, so that mupdf-gl and other tools have no problem signing fields PDF documents generated by ConTeXt? Many thanks for your help, Pablo -- http://www.ousia.tk

UTF-8 characters being dropped from typefile
by ntg＠scorecrow.com 11 Nov '20

11 Nov '20

Sorry for this really, really basic question but... I have the following 3 line source file: \starttext \typefile{test-listing.txt} \stoptext The file "test-listing.txt" is UTF-8 and includes the character U+25B8 (black right-pointing small triangle) which is being dropped from the output. The console shows: fonts > checking > char ▸ (U+025B8) in font 'LMMono12-Regular' with id 8: missing Which explains why the character is being dropped. What I don't understand is why is LMMono12-Regular being used? I thought I had read somewhere that TeX Gyre fonts were now the default (I'm on ConTeXt ver: 2020.11.05 23:01 LMTX) ? If not, is there an installation level config setting to make them the default or do I need to work out the relevant \start ... \stoptypescript commands? Thanks in advance. -- Bruce Horrocks Hampshire, UK

Reverse traversing of xml.collected()?
