can typesetbuffer use the same engine?
by Rik Kabel 05 Nov '21

05 Nov '21

Hello brain trust, How can \typesetbuffer be instructed to use the same engine as the document which contains it? With the following example: \startbuffer[Buffer] \startTEXpage \contextmark \stopTEXpage \stopbuffer \starttext \contextmark\ \typesetbuffer[Buffer] \stoptext I get "MKIV LMTX" when it is processed with context --luatex. I want the buffer to be processed as MkIV. -- Rik

new upload
by Hans Hagen 05 Nov '21

Hi, The latest lmtx upload has this: \starttext \dorecurse{10} { \dorecurse{20}{test #1 } \dorecurse{10}{\insertlinebefore{BEFORE 1/#1}} \dorecurse{20}{test #1 } \blank } \page \dorecurse{10} { \dorecurse{20}{test #1 } \insertlinebefore{BEFORE 1a} \insertlinebefore{BEFORE 1b} \insertlineafter {AFTER 1} \dorecurse{20}{test #1 \hbox{\hbox{\hbox{\footnote{!}}}}} \dorecurse{20}{test #1 } \insertlinebefore{BEFORE 2} \insertlineafter {AFTER 2} \dorecurse{20}{test #1 } \blank } \page \dorecurse{20}{before #1 } \insertblankbefore[big]% \insertlinebefore{\bf patch starts here}% \insertblankbefore[2*big]% \dorecurse{20}{between #1 } \insertblankafter[2*big]% \insertlineafter{\bf and ends here}% \insertblankafter[big]% \dorecurse{20}{after #1 } \stoptext so, some experimental injection mechanism (using some upgraded low level \vadjust related trickery). (now back to the math font mess with Mikael ... so if math lovers have test cases ... it's about time to deal with persistent issues as I don't see/expect math fonts being made more consistent than they are now so we can add tweaks to the goodie files as we go) 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 -----------------------------------------------------------------

escape io.fileseparator in Windows
by Pablo Rodriguez 04 Nov '21

04 Nov '21

Dear list, I have the following sample: \starttext \startluacode main_file = document.files[1] if file.pathpart(main_file) == "" then main_filename = file.nameonly(main_file) main_filename_win = main_filename else main_filename = file.pathpart(main_file):gsub(io.fileseparator, "/") .. "/" .. file.nameonly(main_file) docx_file = main_filename .. "-file.docx" epub_file = main_filename .. "-file.epub" if os.name == "windows" then main_filename_win = file.pathpart(main_file) .. io.fileseparator .. file.nameonly(main_file) docx_file_win = main_filename_win .. "-file.docx" epub_file_win = main_filename_win .. "-file.epub" end end if os.name=="windows" then context(docx_file_win) os.execute("copy " .. docx_file_win .. " aeae") else context(docx_file) end \stopluacode \stoptext If I run it on Windows, context(docx_file_win) cannot deal with the backslash, so I get: .document-file.docx So it is impossible that os.execute may work with copy. Running it with Linux, I get "./document-file.docx". How can I get the io.fileseparator or escape the backslash in main_filename_win above? Many thanks for your help, Pablo -- http://www.ousia.tk

Hyphenation on digits
by Jairo A. del Rio 03 Nov '21

03 Nov '21

Hi, list. I want to know if ConTeXt provides an option to automatically hyphenate/break digits as if they were alphabetic characters. Example, in a narrow page I expect something like that (I've used (-) for an optional hyphen): *π = *3.141592653(-) 58979323846264(-) 33832795028841(-) 97169399375105(-) ... I found myself unable to read a satisfactory solution in the mailing list archive nor other TeX related resources. Maybe LMTX has some magic for that? Cordially, Jairo

\doifinstring: strange characters on the output
by Tomas Hala 02 Nov '21

02 Nov '21

Hi all, I noticed that \doifinstring produces quite strange output if a command follows immediately (or with any amount of spaces) after the substring I am searching for: -------------------------------------MWE \starttext \def\xxx{asdf \bf Z:\bf asdf} % strange \def\xxx{asdf \bf Z: \bf asdf} % strange \def\xxx{asdf \bf Z:: \bf asdf} % OK \def\xxx{asdf \bf Z: text \bf asdf} % OK \def\xxx{asdf \bf Z:{} \bf asdf} % OK \doifinstring{Z:}{\xxx}{yes!} \stoptext ----------------------------------OUTPUT fbf@yes! fbf@yes! yes! yes! yes! ---------------------------------------- If I insert another character, text or {} between them (with or without spaces), all is ok. I would like to ask what is the cause of this behavior and how to use the \doifinstring to prevent the "fbf@" on the output. Best wishes Tomáš

check installed program using Lua
by Pablo Rodriguez 02 Nov '21

02 Nov '21

Dear list, is there a way if a program is installed on the computer using Lua. I have the following sample: \starttext \startluacode filename = tex.jobname .. ".pdf" os.exec("dir " .. filename) \stopluacode \stoptext Is there a way to wrap os.exec() in the sample so that it only runs if "dir" is available? I know that os.name would be an option here, but not in my real world document. Many thanks for your help, Pablo -- http://www.ousia.tk

new upload
by Hans Hagen 02 Nov '21

02 Nov '21

Hi, I uploaded a new lmtx. There is a new low level manual (lowlevel-localboxes) that describes the extended local boxes interface as well as a layer on top. New is that we have classes which makes this (engine) mechanism more useable. It definitely is some low level mechanism but you can for instance use if for high performance efficient maginal notes and line numbering in controlled situations. (There is some room fro optimization in the engien but I deal with that later.)

Cannot access Lua function
by kauśika cittūr 02 Nov '21

02 Nov '21

Dear list, In one of my documents I have this lua block – \startluacode local metadata = lpdf.getmetadata(); ⋮ \stopluacode to modify some metadata fields. The file compiles with the latest LMTX (2021.10.28) without any errors but no PDF is produced. In the log, the following line is present : backend > blocked > function 'getmetadata' is not accessible I recall that this was working just fine some days back. Please advise. Thanks, kauśika

SyncTeX setup
by Henning Hraban Ramm 01 Nov '21

01 Nov '21

Hi, has anyone a working SyncTeX setup with ConTeXt LMTX for anything else than TeXshop? With LaTeX, it works for me with Skim (+ Atom/Textadept/TeXworks) and TeXstudio. And in TeXshop we got our own parser. But can we expect others to adapt to our “superior” SyncTeX format? (I don’t understand the format yet and can’t tell what’s the difference.) Hraban

\externafigure and \at do not work together
by a badin 01 Nov '21

01 Nov '21

Hello, perhaps this is how it is supposed to work, but: \externalfigure[clock.jpg][clock] \starttext \at[clock] refers to a clock \stoptext produces "?? refers to a clock", instead of "1 refers a clock" --- the wiki of \at says, that labels of figures can be refered to. Is this a bug, or can only some labels be refered to? I was able to fix it using: \reference[clock]{\externalfigure[clock.jpg]} \starttext \at[clock] refers to a clock \stoptext and \externalfigure[clock][] \starttext \at \stoptext produces an interesting artwork... so I thought maybe this could be a bug. LMTX 2021.10.21 Best, Andrej
