Replacement mechanism bug in LMTX?
by denis.maier＠ub.unibe.ch 24 Mar '21

Ah, I've now realized that the \blockligatures needs to be activated as a font feature... So forget about this point. But, it still looks like ligature prevention with \replaceword is not working with lmtx, but it works with --luatex. ---------------------------------------------------------------------------- % these don't prevent ligatures \replaceword[eka][auffasse][au{ff}asse] \replaceword[eka][auffasst][au{ff}asst] \replaceword[eka][auffasste][au{ff}asste] \replaceword[eka][asdf][jklö] % this works though % block as a font feature \blockligatures[ff] \definefontfeature[default:nolig][default][blockligatures=yes] % finally this here works \startexceptions[de] au{f-}{f}{ff}(f\zwnj f)asse au{f-}{f}{ff}(f\zwnj f)asste \stopexceptions \starttext no replacements\par asdf auffasste auffasse ff \blank with replacements\par \setreplacements[eka] asdf auffasste auffasse ff \blank disable replacements again\par \resetreplacements asdf auffasste auffasse ff \blank disable ligatures via font features\par \definedfont[Serif*default:nolig] asdf auffasste auffasse ff \definedfont[Serif*default] % back to normal font \blank now via exceptions\par \language[de] % this should trigger ligature handling via exceptions auffasste auffasse \stoptext ---------------------------------------------------------------------------- > -----Ursprüngliche Nachricht----- > Von: ntg-context <ntg-context-bounces(a)ntg.nl> Im Auftrag von > denis.maier(a)ub.unibe.ch > Gesendet: Montag, 22.

Formulanumbers in margin
by Adam Reviczky 24 Mar '21

24 Mar '21

Hi, One more question on formulas. How can I get the formula number to be put into the left/right margin instead of left/right inside the text? I have tried the following: \starttext \showframe % figure caption into the margin \setupcaption[figure][location={rightmargin}] \startplacefigure[title=Cow] \externalfigure[cow] \stopplacefigure % this makes the formulanumber disappear % \setupformulas[location={rightmargin}] \startplaceformula[reference=eq1,location={rightmargin}] \startformula c^2 = a^2 + b^2 \stopformula \stopplaceformula \stoptext But the setupformulas will make the number disappear entirely, and the placeformula location doesn't seem to take the margin option. Thanks, Adam

Questions regarding \startexceptions and ligature prevention
by denis.maier＠ub.unibe.ch 22 Mar '21

22 Mar '21

Hi, there's this rather new mechanism for preventing ligatures: \startexceptions[de] au{f-}{f}{ff}(f\zwnj f)asse au{f-}{f}{ff}(f\zwnj f)asste \stopexceptions Two questions: 1. Can you have multiple \startexceptions[de] environments ? Will they accumulate ? (I'm thinking about preparing a general list of exceptions, but of course you will also want individual exceptions...) 2. What is the exact meaning of these four arguments ? {1}{2}{3} is clear, but what about the parentheses ? Best, Denis

Replacement mechanism?
by denis.maier＠ub.unibe.ch 22 Mar '21

22 Mar '21

Hi, last October I've reported a strange bug with \replaceword I know there's the new mechanism for dealing with ligatures, and I still intend to convert the word list to the new format, but I'm still wondering whether that has been fixed. Now, I've been testing with the minimal example below, and it looks there might be another bug with the replacement and ligature blocking mechanism: ------------------------------------------------------ % these don't prevent ligatures \replaceword[eka][auffasse][au{ff}asse] \replaceword[eka][auffasst][au{ff}asst] \replaceword[eka][auffasste][au{ff}asste] \replaceword[eka][asdf][jklö] % this works though \setreplacements[eka] % doesn't block the ff ligature \blockligatures[ff] % finally this here works \startexceptions[de] au{f-}{f}{ff}(f\zwnj f)asse au{f-}{f}{ff}(f\zwnj f)asste \stopexceptions \starttext asdf % replacements work in general auffasste auffasse ff % now via exceptions: \language[de] auffasste auffasse ff \stoptext ------------------------------------------------------ Best Denis On 10/8/2020 3:15 PM, Denis Maier wrote: > Ok, > I've commented the whole nolig-german-wordlist out piece by piece, and > it looks like it comes down to this: > > ``` > \replaceword[eka][auffasse][au{ff}asse] > \replaceword[eka][auffasst][au{ff}asst] > > \setreplacements[eka] > > \starttext > auffasste > auffasse > \stoptext > ``` > > Uncommenting one of the \replacewords makes the wrong replacement > disappear. > But I don't see why "auffasste" should trigger an replacement.

Typing within doifmode leads to error
by Christoph Reller 21 Mar '21

21 Mar '21

Hi, Consider the following MWE: \definetyping[T] \definemode[mode][yes] \starttext \doifmode{mode}{% \startT Bla \stopT} \stoptext Compilation with the currently latest ConTeXt LMTX (ver: 2021.03.17 17:46 LMTX fmt: 2021.3.18) fails with: tex error > runaway error: end of file encountered mtx-context | fatal error: return code: 1 Compilation is successful if I replace doifmode{mode}{...} by \startmode[mode]...\stopmode. Is there anything I'm missing? (This could be a bug.) Cheers, Christoph Reller

(no subject)
by Adam Reviczky 21 Mar '21

21 Mar '21

Hi, Is there a way to have formula numbers showing all prefix segments? When I use prefixsegments, I get the desired numbering in the placelist but not in the formula number itself. For example: \starttext \setupcaption[figure][way=bytext,prefixsegments=1:*] \setupformulas[way=bytext,prefixsegments=1:*] \startsection[title=Section] \startsubsection[title=SubSection] \startplacefigure[list=cow] \externalfigure[cow] \stopplacefigure \startplaceformula[reference=eq1] \startformula c^2 = a^2 + b^2 \stopformula \stopplaceformula \stopsubsection \stopsection \placelistoffigures[criterium=all] \placelist[formula][criterium=all] \stoptext The figure has number 1.1.1 and is in the list as 1.1.1, the formula has number 1.1 but is listed as 1.1.1. I would like to have the formula numbered 1.1.1 as well (as referenced in the placelist), so with section and subsection numbering. Adam

Keeping track of hyphenations
by denis.maier＠ub.unibe.ch 20 Mar '21

20 Mar '21

Hi Is there a way to conveniently track hyphenations ? I've had a look at https://wiki.contextgarden.net/Trackers but couldn't find anything. I'm thinking of something like this: add information about all hyphenated words to the log so that this could be further processed with a script maybe. All the best, Denis

Error "double-free glue_spec"
by Christoph Reller 20 Mar '21

20 Mar '21

Hi, For one of my projects ConTeXt LMTX 2021.03.17 17:46 fails with: error (nodes): attempt to double-free glue_spec node 145, ignored mtx-context | fatal error: return code: 1 Unfortunately, when I try to minimize the project, the error vanishes. I guess I have to send Hans the whole project, or are there other possibilities? Cheers, Christoph
