Re: Math alignment issue

Hi Mikael, I installed anew the latest version and I get still the same bizarre result with math alignment. Please can someone on the list typeset the following in order to see whether the result is correct or not ? %begin 240117-1-bis.tex \definemathsimplealign[alignedcases] [left={\startmathfenced[cases]}, right=\stopmathfenced, align={1:right,2:left,3:left}, strut=yes] \setupformula [location=left] \starttext \samplefile{knuthmath} \startplaceformula \startformula \startalignedcases \NC u'(t) - \nabla \cdot (a(x)\nabla u) + Vu \NC = 0 \NC \mtext{bla bla bla} \NR \NC u(x,0) \NC = u_0(x) \NC \mtext{bla bla} \NR \NC u(t,\sigma) \NC = 0 \NC \mtext{bla bla bla bla} \NR \stopalignedcases \stopformula \stopplaceformula \samplefile{knuthmath} \startplaceformula \startformula \startalign[location=packed,n=2,m=2,align={1:right,2:left},fences=cases] \NC u'(t) - \nabla \cdot (a(x)\nabla u) + Vu \NC = 0 \NC \NC \mtext{bla bla bla} \NR \NC u(x,0) \NC = u_0(x) \NC \NC \mtext{bla bla} \NR \NC u(t,\sigma) \NC = 0 \NC \NC \mtext{bla bla bla bla} \NR \stopalign \stopformula \stopplaceformula \samplefile{knuthmath} \stoptext % end 240117-1-bis.tex Thanks in advance: Otared > On 17 Jan 2024, at 12:09, Mikael Sundqvist <mickep(a)gmail.com> wrote: > > Could your installation be broken? > > /Mikael > > Den ons 17 jan. 2024 11:41Otared Kavian <otared(a)gmail.com <mailto:otared@gmail.com>> skrev: > Hi Mikael, > > Actually it seems that the math alignment stuff has been broken even in version 2023-09-26, since I get also something incorrect, as you can see in the attached PDF. > > Many thanks for your help: Otared > > > >> On 17 Jan 2024, at 11:06, Mikael Sundqvist <mickep(a)gmail.com <mailto:mickep@gmail.com>> wrote: >> >> Hi, >> >> Then there was a problem with the last update.

issue with fonts in current latest (2024.01.08 11:23)
by Pablo Rodriguez 16 Jan '24

16 Jan '24

Dear list, I have the following sample: \definefontfamily[mainface][rm][TeX Gyre Pagella] \definefontfamily[coverface][rm][TeX Gyre Termes] \setupbodyfont[mainface, 16pt] \starttext \startmakeup[standard][style=\bf] \switchtobodyfont[coverface] This is a cover. \stopmakeup This is text. \stoptext Compiling the sample with current latest (2024.01.08 11:23), LMTX puts Latin Modern Roman (no bold) and MkIV puts Termes (no bold). The results with previous latest (2023.09.26 18:19), cover is in Termes bold with LMTX and in Termes regular with MkIV. I guess there might be an issue here. Could anyone confirm this? Many thanks for your help, Pablo

Looking for itemize help
by Jim 16 Jan '24

16 Jan '24

I have \setupwhitespace [big] so that I get "a blank line" between paragraphs. I would like to *not* have "blank lines" before and after my items. For example, if there is more "paragraph text" after the last item I would like to see this structure: ------------------------------------------------------------------ Some text preceding the list of items: a. Item one. b. Second item. This sentence is part of the same paragraph. The next paragraph starts here... ------------------------------------------------------------------ and if there is no "paragraph text" after the last item, I'd like to see this structure: ------------------------------------------------------------------ Some text preceding the list of items: a. Item one. b. Second item. The next paragraph starts here... ------------------------------------------------------------------ Try as I might, I can't find the right options to give to \startitemize. The closest I have found is to start with \startitemize[a,nowhite] but that prevents the "blank line" even in the second case above, which is not what I want. Further, 'packed' and 'joinedup' seem to behave identically here, both leaving "a blank line" before the first item and after the last item. Clearly, I can force a blank line before the following paragraph with a \vskip<the right amount>, but that seems like a crude way to do it. Can someone either enlighten me on either (a) the Right ConTeXt Way to do this, or (b) a document that would tell me this, if I knew to read it? I've looked in the wiki, the not-so-short intro to ConTeXt, and "ConTeXt: an excursion" with no luck. Thanks. Jim

Wiki update
by Taco Hoekwater 16 Jan '24

16 Jan '24

Hi all, I just updated the wiki ConTeXt to 20240108. The <context> tag on the wiki by default uses luametatex (LMTX), but if you want luatex instead (MKIV), you can still do that by using <context mode=“mkiv”>. There have been some problems recently because Hans’ new binaries needed a newer version of various system libraries. I fixed that this morning after Hraban spotted the issue, but it means that there may be wiki pages with ConTeXt processing errors in them now. These can be recognised by either the colorised “error” output, or some cryptic “copy failed” message instead of the actual output. If you see one of those pages, Edit it. For the colorised “error” output you need to make a tiny change to the example itself (because that “error” output is correct as far as the wiki software can tell, so you have to force it to regenerate). For the “copy failed” case, you just have to start an edit and then immediately save again. The wiki will autogenerate any missing examples on save.

Limit of the size of the email message is 100KB.
by luigi scarso 16 Jan '24

16 Jan '24

Hi all, the ml has (as always as far as I can remember) the limit of 100KB for the maximum size of the message. I have noticed that lately several messages are over the limit, and all I can do is write to the sender and discard the message, and this could happen a couple of days later the message has been received. So...just stay within the limit, if you can. -- luigi

I would have thought that what I want to do is not so unusual that ConTeXt does not have the ability to handle it, especially in light of the indentnext=auto feature which shows that (presumably) some people want to handle the text following \stopitemize differently, depending on whether or not the following text is part of the same paragraph. Perhaps I need to go and contemplate the sins of my formatting choices... :-) Jim

too large dimension in current latest

Hi Hans, after updating to current latest (2024.01.08 11:23), I get the following error. This is triggered when compiling XML sources (with extra environment files), so it is not easy to get a minimal sample file. I wonder whehter the message itself could reveal what may be wrong here.

Linebreak in formual

I have following formula \sum_{k=0\\ k\equiv p + 1(\mathrm{mod}\;2)}^{p -1} but the \\ does not break the line below Sigma. How can I achieve this because AFAIK it will work in LaTeX? -- Respect, Shiv Shankar Dayal

Spacing problem in formula
by Shiv Shankar Dayal 15 Jan '24

15 Jan '24

Suppose I want to typeset the formula: 1 - {}^nC_2\tan^2\theta + {}^nC_4 then it appears as if n is power of - and +. The same formula in LaTeX comes out nicely. Is there something I need to change? -- Respect, Shiv Shankar Dayal
