Concerning \installparameterhashhandler and family
by Jairo A. del Rio 10 Nov '21

Hi. Reading at mult-aux.mkxl, I've seen command handlers define, among others, \installparameterhashhandler, However, in files such as those related with symbol management, only \installparameterhandler and \installsetuphandler are. When writing basic modules, sometimes only the "raw" macros above are actually needed. So, what are "parameterset", "hashhander", "rootparameterhandler", etc. for? Where would they ease module writing? Thank you a lot and sorry for the long question. Best regards, Jairo

Any initial thoughts on luau?

Hello, Yesterday, Roblox announced - Luau - https://luau-lang.org/why - mainly adding linting and type-checking features. Being compatible with Lua 5.1 is probably a bummer but nonetheless would be interesting to hear about this from this community. Thank you. best regards, Ramkumar

on luatex.wrapup
by Pablo Rodriguez 08 Nov '21

Hi Hans, I would like to use luatex.wrapup to remove media files that I don’t need anymore once the PDF document is generated. I have realized that luatex.wrapup works at the very end of the PDF generation, but in each run. Is there no way to have a luatex.final_wrapup, when no other run will take place? Many thanks for your help, Pablo -- http://www.ousia.tk

font problem
by skyhorse＠gmx.us 07 Nov '21

07 Nov '21

I am a beginner and not well versed on font processing needs yet. I tried the following simple example, but get an error. I am using the standalone context: "txrun | ConTeXt TDS Runner Tool 1.32" Here is my example: %%%%%%%% \starttext \startformula c^2 = a^2 + b^2 \stopformula \stoptext %%%%% The error I get back from context is: " Sorry, but I can't typeset math unless various parameters have been set. This is normally done by loading special math fonts into the math family slots. Your font set is lacking at least the parameter mentioned earlier. mtx-context | fatal error: return code: 256 " I don't know what special math fonts there are or what a math family slot is. Can you help me out. Or point me to a document that will clear this up for me. Thank you. ---------

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

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
