Very strange error:
by Xavier B. 15 Aug '23

15 Aug '23

After I run context (LMTX version) to my document (attached) I get this error: tex error > tex error on line 540 in file ./dev.tex: The file ended when scanning an argument. I don't know how to start... Can anyone help me? Thanks, Xavier PS: I receive this error after upgrading to MKIV to LMTX. Before with MKIV I get no errors.

split align in formulas
by Xavier B. 14 Aug '23

14 Aug '23

I have this text and the end of the paragraph: Definitivament és el mètode més senzill. L'atribució més antiga que conec d'aquest mètode és de James Tanton \cite{canvi-variable-equacio-segon-grau, james-tanton-web}. \placeformula[eq:james-tanton-canvi-de-variables] \startformula \startalign \NC ax^2 + bx + c = 0 \NC \NR \NC ax^2 + bx = -c \NC \quad \text{transposem } c\NR \NC x^2 + \frac{b}{a} x = - \frac{c}{a} \NC \quad \text{dividim per }a\NR \NC x \left( x + \frac{b}{a} \right) = - \frac{c}{a} \NC \quad \text{factoritzam} \NR \NC (k-D)(k+D) = - \frac{c}{a} \NC \quad \text{canvi de variable} \NR \NC k^2 - D^2 = - \frac{c}{a} \NC \quad \text{suma per diferència} \NR \NC k = \pm\sqrt{ D^2 - \frac{c}{a}} \NC \quad \text{resolem l'equació} \NR \NC x = k - D = \NC \pm \sqrt{ D^2 - \frac{c}{a}} - D\quad \text{desfeim el canvi} \NR \stopalign \stopformula on $D = (\frac{b}{2a})$ i $x = k-D$. and then the formula goes to next page. Is there any way to split align environment? In wiki I could not find nothing. Thanks in advance,

Why overbar is so big
by Xavier B. 14 Aug '23

14 Aug '23

If you run \starttext Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. $\overbar{OA} = 4,2$ \stoptext Then the overbar has the bar in a very long altitude. Can you please, see the output attached.

Nested aligns in formulasjj
by Gerion Entrup 14 Aug '23

14 Aug '23

Hi, I try to typeset a nested align in a formula. However, the results looks really wrong. Here is a MWE: ``` \starttext \startformula \startalign \NC a = \NC (b, c) \quad \text{with}\NR \NC \NC \startalign \NC b \NC = something \NR \NC c \NC = someother \NR \stopalign \NR \NC somelong = \NC bla \NR \stopalign \stopformula \stoptext ``` Am I doing something wrong or are nested aligns not possible? Best, Gerion

Pass string into text background graphic
by Thangalin 13 Aug '23

13 Aug '23

Hi list, I'm attempting to make a stylized border around paragraphs that can span pages. The border runs along the side and the top. (Ideally the top border wouldn't repeat, but that's a minor issue.) The issue I'm having is that the title for the text doesn't always appear. Instead, there's a small gap along the top border where the title should be. Am I going about this the wrong way? % SOT \startbuffer[demo] <html> <body> <div class="concurrent" data-title="Berth 5" data-location="San Diego"> Text Goes Here </div> <div class="concurrent" data-title="Road" data-location="Beale AFB"> Different Text Goes Here </div> </body> </html>\stopbuffer \startxmlsetups xml:xhtml \xmlsetsetup{\xmldocument}{*}{-} \xmlsetsetup{\xmldocument}{html|body}{xml:*} \xmlsetsetup{\xmldocument}{div}{xml:*}\stopxmlsetups \xmlregistersetup{xml:xhtml} \startxmlsetups xml:html \xmlflush{#1}\stopxmlsetups \startxmlsetups xml:body \xmlflush{#1}\stopxmlsetups \startxmlsetups xml:div \setvariable{div}{\xmlatt{#1}{class}}{#1} \start[\xmlatt{#1}{class}]\xmlflush{#1}\stop\stopxmlsetups \startusableMPgraphic{GraphicConcurrent} begingroup; string legend; picture title; picture border; picture bg; numeric tw; numeric th; legend := \MPstring{concurrent}; title := nullpicture; border := nullpicture; bg := textext( "\strut " & legend ); tw := xpart lrcorner bg - xpart llcorner bg; th := ypart ulcorner bg - ypart llcorner bg; addto title also image( fill unitsquare xysized (tw + 8, th) shifted ulcorner multipars[1] shifted 28 right shifted 8 down withcolor white; draw textext.drt( legend ) shifted ulcorner multipars[1] shifted 32 right shifted 3 down; ); addto border also image( for i = 1 upto nofmultipars: draw llcorner multipars[i] -- ulcorner multipars[i] shifted 8 down .. ulcorner multipars[i] shifted 8 right -- urcorner multipars[i] withpen pencircle scaled 0.75 withcolor black; endfor; ); draw image( draw border; draw title; ); endgroup;\stopusableMPgraphic \definetextbackground[TextConcurrentFrame][ mp=GraphicConcurrent, frame=off, topoffset=1em, leftoffset=1em, location=paragraph, ] \definestartstop[concurrent][ before={% \blank[big]% LEGEND: \xmlatt{\getvariable{div}{concurrent}}{data-title}% \blank[big]% \setMPtext{concurrent}{\xmlatt{\getvariable{div}{concurrent}}{data-title}} \startTextConcurrentFrame}, after={\stopTextConcurrentFrame\blank[big]}, ] \starttext \xmlprocessbuffer{main}{demo}{}\stoptext % EOT If I change the following line: legend := \MPstring{concurrent}; to: legend := "some string"; Then the title "some string" is repeated. It seems like the value for \MPstring{concurrent} is being cached in some situations and ignored in others. Essentially, I'm trying to visually offset multiple paragraphs using a left-hand vertical rule along with a top horizontal rule that has a title. Each new "concurrent" section needs its own header that doesn't repeat. Is there a ConTeXt-way to accomplish this feat? Cheers!

side-by-side paragraphs broken?
by Thomas A. Schmitz 13 Aug '23

13 Aug '23

Hi, in more recent versions of lmtx, the side-by-side mechanism appears to be broken; example below. The right-hand paragraph does not respect the margin and backspace setting. The output looks fine in mkiv and with older versions of lmtx (the one from texlive, so 2023.03.10). Not sure if this has been reported yet. All best Thomas \setuppapersize[A4,landscape] \setuplayout[height=fit, width=middle, header=0cm, footer=0cm, leftmargin=2cm, topspace=1.2cm, backspace=1.5cm] \showframe \defineparagraphs[Half] [n=2] \setupparagraphs [Half] [before=,after=,distance=3em,align={normal,hanging},tolerance={stretch,verytolerant}] \setupparagraphs [Half] [1] [width=0.43\textwidth,tolerance={stretch,verytolerant}] \setupparagraphs [Half] [2] [rulethickness=2mm,rulecolor=gray,rule=on,tolerance={stretch,verytolerant}] \starttext \startHalf \input ward \nextHalf \input knuth \stopHalf \stoptext

Font switching, default features, and a request
by Hamid,Idris 13 Aug '23

13 Aug '23

Dear gang, Consider the following example: ============== \setupdirections[bidi=global,method=one] \startTEXpage[offset=1em,width=14in] \definedfont[almfixed*arabic] \switchtobodyfont[almfixed*arabic] \switchtobodyfont[almfixed] % \addff{arabic} \startbuffer[] \startlines الثَّعْلَبُ الْأَسْمَرُ السَّرِيعُ يَقْفِزُ فَوْقَ الْكَلْبِ الْكَسُولِ! The quick brown fox jumps over the lazy dog! \stoplines \stopbuffer {\tfxx \type{\tfxx} \getbuffer} {\tfx \type{\tfx} \getbuffer} \type{\tf} \getbuffer {\tfa \type{\tfa} \getbuffer} {\tfb \type{\tfb} \getbuffer} {\tfc \type{\tfc} \getbuffer} {\tfd \type{\tfd} \getbuffer} \stopTEXpage ============== There are three font switches to choose from: ============== \definedfont[almfixed*arabic] \switchtobodyfont[almfixed*arabic] \switchtobodyfont[almfixed] ============== Let's toggle one at a time: 1) \definedfont[almfixed*arabic] a) gives us the correct bidi output, but only for the \tf size b) is ignored for every other size switch. a) and b) are expected behavior. 2) \switchtobodyfont[almfixed] a) gives us Arabic-script bidi output, b) exhibits no Arabic-script features c) gives the same result for each size switch This means that the fontfeature "arabic" -- already predefined in ConTeXt (font-pre.mkiv) -- is not explicitly applied. Curiously, invoking \addff{arabic} does not affect the output. Why is it that \addff{arabic} does not work here? 3) \switchtobodyfont[almfixed*arabic] suppresses the font entirely and we're back to Latin Modern for all sizes. Assuming that this is expected behavior, it appears to follow that fontfeatures cannot be invoked for \switchtobodyfont and the like, only from within the typescript read by \switchtobodyfont etc. ======= REQUEST: Since ALMFixed is already distributed with ConTeXt, could Hans make the fontfeature "arabic" default for this font? That is \switchtobodyfont[almfixed] should automatically a) give us Arabic-script bidi output (already there), b) exhibit Arabic-script features (missing) c) gives the same result for each size switch (already there) (Indeed, it would be useful to have *arabic-predefined typescripts/bodyfonts for a few other commonly available/used Arabic fonts as well. Would be willing to make a list at some point, test, etc.) Thank you in advance for considering this request.
