Fuzzy lines
by Henning Hraban Ramm 21 Jan '22

Hi MetaFans, is it possible to get lines with Metapost that look like they were drawn with a pencil or brush? Some vector graphics apps (in my case: Affinity Designer) can use such naturally looking brushes for vector graphics (and I don’t know how they do it), but I’d like to automate/parametrize some designs, and that would finally be a reason to learn Metapost...

Defining new float types fails in LMTX
by Marco Patzer 18 Jan '22

18 Jan '22

Hi! Apologies for spamming this list with my all the floaty stuff. There's an issue with defining new floats in LMTX in combination with bottom placement. The following works in MkIV, but throws an error in LMTX: I'm ignoring this; it doesn't match any \if. mtx-context | fatal error: return code: 256 \setupfloat [figure] [default=bottom] %% fails %% [default=top] %% works \definefloat [foo] [foos] [figure] \starttext \startplacefigure [title=Foo] \framed{Foo} \stopplacefigure \startplacefoo [title=Bar] \framed{Bar} \stopplacefoo \stoptext Marco LMTX 2021.11.26 11:38

SimpleSlides and Visual counters
by Otared Kavian 16 Jan '22

16 Jan '22

Hi all, in particular Aditya M. and Thomas A.S., It seems that the visual counter in SimpleSlides module (the version I have from ConTeXt Garden is from 2014) does not work fine with the latest LMTX. Is the issue is known ? If so, is there a new version of SimpleSlides in which the issue has been fixed ? Best regards: Otared

Errors in source files return success
by Marco Patzer 26 Dec '21

26 Dec '21

Hi! ConTeXt can detect issues in the sources and report them on the console with the argument --errors or with \enabledirectives [logs.errors]. The return value is still “0” (=success) even with errors present. Right now I use a script that parses the log file and lets me know if a run has issues. However, it would be great if context could return a non-zero value if errors are present. I've found that \enabledirectives [logs.errors=missing characters] returns “1” if characters are missing. Lovely! Undefined control sequences always return 1 (a TeX thing I believe and not related to the macro package). But undefined control sequences don't show up on the console as the other errors do if general output (except errors) is silenced e.g. with context --silent --noconsole --nostatistics --errors <file> The question is, what other directives can be enabled that make context return a failure? Is there a way to return failure if *any* error is encountered or do they need to be enabled each individually? And is there a way to show hard TeX errors as undefined control sequences as a “possible issue” if output is silenced? MWE: %% enables logging of errors same as --errors AFAIK \enabledirectives [logs.errors] %% makes context return 1 on missing chars, great! %% \enabledirectives %% [logs.errors=missing characters] \starttext %% missing characters 𝒜 %% missing figure \externalfigure [foo] %% \end occurred inside a group at level 1 %% ### semi simple group … entered at line \startalignment [middle] foo %% missing references See \in{section}[sec:none]. %% undefined control sequence %% \undefined \stoptext Marco

location=outer causes bad page break in LMTX
by Marco Patzer 25 Dec '21

25 Dec '21

Hi! In the following example “Lorem ipsum” sits on an otherwise empty page in LMTX. Output is as expected with MkIV. Has the interface changed or may it be a bug in LMTX? \starttext \null\godown [15.5cm] \samplefile{knuth} Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor \startplacefigure [location=outer] \externalfigure \stopplacefigure \samplefile{knuth} \stoptext Marco LMTX 2021.11.26 11:38

Regular online meet-up
by Henning Hraban Ramm 14 Dec '21

14 Dec '21

Hi all, already for a while I wanted to suggest a regular online meet-up, just to chat or discuss ConTeXt and the world. Participants of the just finished meeting already know the BigBlueButton “room”, and without the difficulty of a auditory in presence and a weak DHCP, we should have even less problems with it. I’d offer this monthly, 2–3 hours, and let’s see if it stands the test. Now, if you’d like to participate, which times would fit you (weekdays, daytime...)? Warm regards, Hraban

by denis.maier＠unibe.ch 09 Dec '21

09 Dec '21

Hi, for a current project I'll need different variants of underbars. - A normal underbar - A dotted underbar - A combination of both Is there a way to combine them? I was hoping to have the dotted variant above the normal bar. This is not working %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \starttext \underbar{asdf} \underdot{asdf} \underbar{\underdot{asdf}} \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Best, Denis

Bad linebreak in figure caption
by Marco Patzer 03 Dec '21

03 Dec '21

Hi! The caption "FOO" runs into the right figure's caption: \setuplayout [width=18.4cm] \setuptolerance [verytolerant, stretch] %% even with stretch \starttext \startplacefigure \startfloatcombination \startplacefigure [title=Unexpectedly unnecessary FOO-BAR whatever] \framed[width=.4\textwidth]{} \stopplacefigure \startplacefigure [title={Lorem ipsum dolor siit amet}] \framed[width=.4\textwidth]{} \stopplacefigure \stopfloatcombination \stopplacefigure \stoptext Why does ConTeXt not break the line between "unnecessary" and "FOO"? How to kindly persuade it to do so? Marco LMTX 2021.11.26 11:38

new upload
by Hans Hagen 01 Dec '21

Hi, (1) See previous mails on the list (those who requested it have to wikify): - mixed bars (with limitations) - horizontal registers (flushing) (2) As a side effect of reshuffling some code (as well as being complete): - \boxshift 0 = 10pt - hbox shift -10pt{...} These box shifts are what \moveleft, \raise etc use as well as some internal constructors like math. (3) Because there is no reason for a limitation to rules and boxes we can now also do: - x\cleaders \glyph`! \hfill x where as usual \glyph taking some options. (4) A few internals that users are unlikely to encounter (unless they mess with weird tokens in lua). Hopefully no bad side effects of all this (and if so, easy to solve).
