Textadept no longer supported?
by Jairo A. del Rio 28 Aug '22

28 Aug '22

Hi, list. Last time I installed my ConTeXt distribution from scratch, I've noticed Textadept files are no longer in the distribution. I've tried SciTE but it's broken in Ubuntu as code highlighting just doesn't work. Has something changed? Is it possible to get those files from an older version? Thanks in advance. Best regards, Jairo

Understanding font errors
by denis.maier＠unibe.ch 26 Aug '22

Hi, I've just noticed I'm getting error messages related to fonts: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% fonts > checking > char G (U+00047) in font '' with id 0: missing fonts > checking > char r (U+00072) in font '' with id 0: missing fonts > checking > char a (U+00061) in font '' with id 0: missing fonts > checking > char f (U+00066) in font '' with id 0: missing fonts > checking > char i (U+00069) in font '' with id 0: missing fonts > checking > char k (U+0006B) in font '' with id 0: missing fonts > checking > char [space] in font '' with id 0: missing fonts > checking > char m (U+0006D) in font '' with id 0: missing fonts > checking > char t (U+00074) in font '' with id 0: missing fonts > checking > char L (U+0004C) in font '' with id 0: missing fonts > checking > char b (U+00062) in font '' with id 0: missing fonts > checking > char e (U+00065) in font '' with id 0: missing fonts > checking > char l (U+0006C) in font '' with id 0: missing %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% What exactly is that supposed to mean? There does not seem to be a problem in the resulting PDFs. What should I do to debug this? Best, Denis

No error when loading a non-existent module
by Max Chernoff 26 Aug '22

26 Aug '22

Hi all, If you load a non-existent module, ConTeXt issues a minor warning, but otherwise proceeds as normal: MWE: \usemodule[doesnt-exist] \starttext Hello world! \stoptext I think that this behaviour should be changed so that a fatal error is issued when a loaded module cannot be found. Plain TeX, LaTeX, and OpTeX all throw an error whenever their versions of modules cannot be found, so ConTeXt is the odd one out here. There are 3 scenarios that I can think of for when you attempt to load a module, but it cannot be found: 1. A module provides some new command "\somecommand" In this case, loading the module will quietly fail, but an undefined control sequence error will be issued whenever you use "\somecommand". This disguises the root problem, which is that the module was never loaded, potentially confusing users. 2. A module changes the layout of a document In this case, the layout of the document would be unchanged by the module. If you're looking at every document, then this would be obvious; however, if you're using some batch processing system, you could unknowingly send out incorrectly-styled documents quite easily. 3. You load a module that provides some command, then never use it This is the only case where the new error would break any documents. However, this case should hopefully be pretty rare since it's pointless to load a module then never use any of its features. Making this change could potentially break some documents that currently work, but I think that this change is worth it, since I'd rather have something break loudly (throwing an error) rather than silently (producing a semi-corrupt document). Thanks, -- Max

String substitution using regular expressions and backreferences
by Thangalin 26 Aug '22

26 Aug '22

Hi list, I'm looking to perform text replacements. \definereplacement[SubstPostmeridian][ match={[Pp].[Mm].]}, replace={\cap{pm}} ] The \replaceword command doesn't handle periods well. The translate module doesn't seem flexible enough to cover edge cases. Consider the following example document containing both sample inputs and sample outputs: \starttext {\bf Markdown Input} Our grandmother clock rang 11 p.m. and we fled. Our grandmother clock rang 11 p.m., so we fled. Our grandmother clock rang 11 p.m. We fled. \blank[big] {\bf \ConTeXt{} Output} Our grandmother clock rang 11 \cap{pm} and we fled. Our grandmother clock rang 11 \cap{pm}, so we fled. Our grandmother clock rang 11 \cap{pm}. We fled. \stoptext It would be most convenient to write: % Strip periods from p.m. \definereplacement[SubstPostmeridianLowercase][ match={[Pp].[Mm]. ([^:upper:])}, replace={\cap{pm} \1} ] % Preserve terminal period for p.m. (e.e. cummings notwithstanding) \definereplacement[SubstPostmeridianTerminal][ match={[Pp].[Mm]. ([:upper:])}, replace={\cap{pm}. \1} ] % Apply a macron for lowercase 'c' (McAnulty, McGenius, etc.) % Well, not quite a macron: https://tex.stackexchange.com/q/364024/2148 \definereplacement[SubstMac][ match={Mc([:upper:]\w)}, replace={M\macronbelow{c}\1} ] The \1 may be problematic. Other sigils include $1 and #1, which may also have issues. Thank you!

I know that I can just modify "cont-en.mkxl" or > "context.mkxl", but those can be overwritten by updates. no, these files are always read runtime (when present); personally i only use cont-loc fdor things like this: \enablemode[atpragma] \enablemode[*allfonts] \enabletrackers[pages.timing] % \enabletrackers[system.usage=summary] and there is very little in cont-new while in cont-exp i only have some features or optimizations enabled that i run for a while before they become default we're not going to add features that preloads extra stuff. i don't even want to think about possible interference because who knows what those systems set and do, and there's also order involved; i can even imagine that one then has to bump token memory. also, from the perspective of support it is handy to know that a standardized format is used normally loading files is fast enough once the os has them cached and afaiks tikz is not the fastest subsystem anyway so that probably impacts runtime anyway 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 -----------------------------------------------------------------

Hello! I have a ConTeXt Lua Document where I need to have headertexts. When running the enclosed file I get 6 pages where only page 1 and 2 have header texts and the others none. — Why is that? Thanks for hints! Kind regards Willi

faltal error: return code: 1

Hans, using latest from today (and the previous one) with the following source: \starttext \doloopoverlist{\tf,\ss,\tt} {\bgroup\recursestring% \doloopoverlist{\tf,\it,\bf,\bi,\sc} {\bgroup\recursestring\dorecurse{26} {\character{\recurselevel}̱ }\par}\egroup} \stoptext I get the following error: mtx-context | fatal error: return code: 1 But when checking the sources, no error is found: $ mtxrun --script check test-file.tex no error Just in case it helps, creators are "LuaMetaTeX 2.10 20220818 + ConTeXt LMTX 2022.08.25 17:43". I don’t know whether I’m missing something (in that case, the error message should be more verbose). Many thanks for your help, Pablo
