Hi, I am not trying to install tikz related modules from ctan rather than copying them from the minimals. I notice that the latest version of pgfplot now gives an error: token call, execute: ...etatex/texmf-context/tex/context/base/mkiv/l-sandbox.lua:180: module 'prepcontour' not found: no field package.preload['prepcontour'] no file '/usr/local/share/lua/5.4/prepcontour.lua' no file '/usr/local/share/lua/5.4/prepcontour/init.lua' no file '/usr/local/lib/lua/5.4/prepcontour.lua' no file '/usr/local/lib/lua/5.4/prepcontour/init.lua' no file './prepcontour.lua' no file './prepcontour/init.lua' pgfplots has a line which is essentially equal to \directlua{require(prepcontour);} https://github.com/pgf-tikz/pgfplots/blob/da2acbe847db88d1b916b324562161a1c… It also ships with a prepcontour.lua file: $mtxrun prepcontour.lua /opt/luametatex/texmf-modules/tex/generic/pgfplots/lua/prepcontour.lua However, it is not found by the require(...) file. The value of my LUAINPUTS variable is: mtxrun --expand-var LUAINPUTS .;.;{home:texmf,!!selfautoparent:texmf-project,!!selfautoparent:texmf-fonts,!!selfautoparent:texmf-local,!!selfautoparent:texmf-modules,!!selfautoparent:texmf-context,!!selfautoparent:texmf-linux-64,!!selfautoparent:texmf}/tex/{context,plain/base,generic}//;{home:texmf,!!selfautoparent:texmf-project,!!selfautoparent:texmf-fonts,!!selfautoparent:texmf-local,!!selfautoparent:texmf-modules,!!selfautoparent:texmf-context,!!selfautoparent:texmf-linux-64,!!selfautoparent:texmf}/scripts/context/lua// So, the above file should have been found, but it isn't. How can I fix this. FWIW, here is a minimal example: \directlua{require("prepcontour");} Thanks, Aditya

how to setup path of ConTeXtLMTX for MacVim?
by Jeong Dal 12 Dec '21

12 Dec '21

Hi, Recently, I have a problem to use vscode, so I tried MacVim for ConTeXt. It worked fine. But it uses context in TeXLive instead of using it in ConTeXtLMTX. I’d like to use LMTX which is installed in ~/ConTeXtLM/tex/... How to redirect the path for ConTeXt in MacVim? Thank you. Best regards, Dalyoung

upload ... new feature
by Hans Hagen 10 Dec '21

10 Dec '21

Hi, This time the lmtx upload has a (for some maybe) interesting new features: runtime pdf encryption. context --ownerpassword=foo [--userpassword=bar] [--permissions="see context --help --expert"] One can also use the document banner line, like: % ownerpassword="foo" userpassword="" permissions="print,extract,quality" Now, this is a feature that relies on the viewer to deal properly with it as we only support the not depricated method (why bother with the old stuff). acrobat : it took some effort (and trial and error) to make that one happy but it seems to work ok summatra : the one i use, it works ok in the latest greatest (i use 3.3.13418) mutool : okay but sometimes with a warning (i have a workearound but not enabled it because i consider it to be a bug) qpdf : happy but check gives a permissions warning (understandable as that is a real mess) firefox : opens ok in the latest version (pdf.js) chrome : can't handle the revision level we use (the rest is depricated so i consider it a lack of feature for now) edge : idem okular : my (windows) version is too old xpdf : not up to it yet foxit : (i never use it, but tried ... it's code seems to be what is used in chrome) doesn't work with this revision I would be surprised if the native apple viewer works but I can't test that. Given earlier pdf threads, I wanna check with Michal Vlasák what can be improved. Performance is okay, the luametatex manual takes 1% more runtime and that's within the runtime measurement margin that I use. I didn't test with external images yet but will do that so don't expection yet. It will probably take a few months to reach a stable state anyway. (But ... afaiks tikz pdf generation, which is also somewhat alien to context, seems to work). Hopefully I didn't mess up the unrelated code, 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 -----------------------------------------------------------------

All Equations

Since I never used math with ConTeXt, I tried to replicate XKCD 2034 as an exercise (see below and attached). I’d like to put it on the wiki and in my book. I know this is nonsense, but I’d like to do it right. In some cases I’m unsure which symbol the author meant, e.g. p or \rho, 0 or O, 1 or I or | ... Yes, I could have used proper Unicode characters (ρ, π etc.). Can you answer my questions (%? in the source)? (Partly TeX related, partly math/physics related.)

Initial release of SBL bibliographic rendering and biblio wishlist
by Joey McCollum 10 Dec '21

10 Dec '21

A while ago, I mentioned in a thread on the mailing list that I was working on a new bibliographic rendering for the SBL citation style. After additional testing and implementation of various features (e.g., an authorconversion that inverts the first author and prints all subsequent authors in normal order, an author-title sort order for bibliographic entries, support for shorthands/abbreviations, support for Citation Style Language locators, and support for biblatex-style citation macros that intelligently move punctuation that follows them). While optimizations for performance, simplifications of the code, and new feature additions are still desirable, the module is in working condition and can now be incorporated in a future ConTeXt update. The new .lua and .mkvi files for the SBL rendering, updated publ-aut.lua and publ-imp-author.mkvi files, and some new code intended to be incorporated into publ-ini.lua and publ-ini.mkiv can all be found in project GitHub repo at the https://github.com/jjmccollum/context-sbl. While I worked on this module, Denis Maier (who provided valuable feedback and suggestions throughout) and I put together a wish list of new features we would like to see implemented in the publications support core modules. We put together the list with Hans and Alan in mind, but any help is appreciated! The list follows: - Probably the most urgent need is for field inheritance mappings through crossrefs to be fixed. These should be customizable in bibliographic specification .lua files (e.g., publ-imp-sbl.lua), or at the very least, they should follow the pattern of biblatex. As it is currently implemented, field inheritance seems to map any field from the cross-referenced entry to a field *of the same name* in the current entry if it doesn't have a field of this name already. But this causes serious problems when one needs to check if an entry has a given field (such as "shorthand") at all; specifically, the \btxdoif macro will execute its argument if the current entry *or any entry it cross-references* contains a field with that name. What we want is a more disambiguated mapping of inherited fields: for many common entry types (such as @book, @collection, @reference, @proceedings, and @inbook, @incollection, @inreference, and @inproceedings), biblatex maps the title field of the cross-referenced entry to a different-named field in the lower-level entry (e.g., maintitle -> booktitle -> title, maineditor -> bookeditor -> editor, etc.). - A mechanism for setting default field values (e.g., "pagination", "options") by category in the .lua file for a given specification. (In the SBL spec, for instance, an entry of category @ancienttext or @classictext should have options={skipbib=true} by default.) If the user actually specifies this field in an entry, then the default value would be overwritten. - If it hasn't been done already, the \btxdoifelsecitedone macro defined in the cont-new.mkiv file in https://github.com/jjmccollum/context-sbl should be implemented in publ-ini.lua and publ-ini.mkiv. - Related to the previous entry, the ability to remove existing entry tags from the "collected" or "tobesaved" lists defined in publ-ini.lua. This would allow us to override the usual list registry rules of \cite based on the values of, say, an entry's category, "type" field or "options" field. - General support for the useauthor, useeditor, usetranslator, skipbib, and skipbiblist entry options from biblatex. These could be implemented as citation-level btx options (currently, useauthor already is implemented for the SBL style). - Support for disambiguation in "author" citations made with the "name" authorconversion. Publications support already allows us to map different versions of the same name (e.g., "John Doe" and "J. Doe" to a single value. But ideally, the publications support module should also check if surnames are shared by distinct authors, and if so, it should then check for distinct first and middle initials, and then distinct full names, until it finds a difference. The shortest distinct renderings should then be used for the "name" authorconversion. Different bibliographic renderings have different rules for this, so implementations of these different rules (detailed at https://docs.citationstyles.org/en/stable/specification.html#disambiguation) would be ideal. - General support for *ibidem* (same entry), *idem* (same author), and *op. cit.* (same title) tracking in the publ-ini module. These could be implemented with default settings that could be overridden as needed in individual specifications. Following biblatex, the user should be able to specify yes/no "ibidtracker", "idemtracker", and "opcittracker" options via \setupbtx. The publ-ini.mkiv file already defines macros like \btxdoifsameaspreviouscheckedelse, \btxdoifsameaspreviouselse, and \btxdoifcombiinlistelse to help with this sort of thing in the bibliographic list, but we'd like something analogous for inline citations. Specifically, we'd like a way to retrieve (or compare) the tag, author, and title of the last entry cited in the current mode (where the mode may be in the main document or a footnote/endnote). A further \btxsetup option could control how locally the tracking should be done (i.e., if the trackers should reset at the start of a new chapter, new section, new page, etc.). In addition, it would also be good to copy the \mancite command from biblatex, which manually resets these trackers when it is invoked. - General support for CSL locator macros, whose basic usage is described in https://pandoc.org/MANUAL.html#citation-syntax. The citation style locales defined at https://github.com/citation-style-language/locales have been defined for various languages already, and their printed renderings can be implemented according to individual specifications (perhaps using the language-dependent \setupbtxlabeltext macro). A template for this can be found in the SBL rendering at https://github.com/jjmccollum/context-sbl. - ConTeXt might benefit from a predefined parenthetical delimitedtext environment similar to "quotation" and "quote". Currently, I define such an environment in publ-imp-sbl.mkvi as follows: ``` % Nested parentheses (used for things like publisher and institution blocks) should alternate between proper parentheses and brackets \definedelimitedtext[paren][quotation][location=text,left={(},right={)}] \setupdelimitedtext[paren:1][left={(},right={)}] \setupdelimitedtext[paren:2][left={[}, right={]}] \setupdelimitedtext[paren:3][left={(},right={)}] \setupdelimitedtext[paren:4][left={[}, right={]}] ``` But a general environment of this nature (perhaps supporting alternating parentheses/brackets to arbitrary depth?) may be useful for other citations styles and more general typesetting purposes, as well. - Per a discussion I had earlier with Hans, a language-specific mechanism for moving trailing punctuation after a \quotation or \quote block so that it is inside that block (in accordance with "American" punctuation rules) would be helpful. - The ConTeXt distribution should be updated to include the authortitle sort method in publ-aut.lua and the invertedfirst authorconversion setups in publ-imp-author.mkvi. These are already defined in the copies of these files in the sbl-context GitHub repo. - Optimized implementations in the ConTeXt core for the following macros, some unoptimized versions of which are defined in publ-imp-sbl.mkvi (at https://github.com/jjmccollum/context-sbl): - \doifprefix, \doifprefixelse, and \doifnotprefix - \doifsuffix, \doifsuffixelse, and \doifnotsuffix (the \btx_sbl_doifendswithpunct macro is a more specific template for this; if you think the punctuation-specific macros would also be useful in general, then they could be implemented in the core, as well) - The "\clf_" macros mentioned in the "NOTE FOR HANS" near the start of publ-imp-sbl.mkvi should be accessible through exposed helper functions. Many of these features (and some others that are specific to the SBL rendering) are marked with "TODO" notes in publ-imp-sbl.mkvi. I'm getting ready to start my PhD research in a few months, so I don't expect to have as much time to develop the SBL rendering in the near future, but I can try to patch things up as needed if anyone runs into any problems in the near-term. Thanks to everyone on the mailing list who answered my questions throughout this process and for your continuing help in the future! Joey

\WORD regression
by Henning Hraban Ramm 10 Dec '21

10 Dec '21

\starttext \WORD{größer} \stoptext \WORD used to handle "ß" correctly, i.e. convert it to "SS"; now it makes "sS". (If the current font contains an uppercase ß that would be even better, but those are rare). I can’t tell when it changed (some LMTX versions ago) and can’t check MkIV, since "mtxrun --generate --luatex" doesn’t work. Hraban

xml processing: if elseif else / switch case
by denis.maier＠unibe.ch 10 Dec '21

10 Dec '21

Hi, I was wondering whether we have tests similar to <if-else if-else> or <switch case> in context's xml processing. (And even in context more general...) I have found these doifelse tests, but elseif doesn't seem to exist. Is that correct? If yes, could that be added? Of course, you can always just nest doifelse-constructs, but that will become ugly quickly. Being able to specify multiple branches would be handy. Best, Denis
