Placing identical images in a n x m grid shows extra space every two rows. Also the vertical and horizontal spaces are different. There is probably a reason for this to happen, but how to avoid it ? .Floris [MWE] \starttext \startTEXpage[offset=10mm, pagestate=start] \startcombination[nx=3, ny=5] \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \startcontent\externalfigure[p1-4_4-01-56-25-015.png][height=.2\textwidth,width=.2\textwidth]\stopcontent \stopcombination \stopTEXpage \stoptext [/MWE]

itemize
by Hans Hagen 15 Aug '23

15 Aug '23

Hi, There has been some additions to itemize wrt columns. One problem with columns is that we have a 'cross page' and 'balancing' situation. The existing columns features has been improved a bit. That leaves the problem that mixing single and multi columns is not really tex's strong point. So, when Mikael and I were looking at one of his documents that mixes a lot of math into itemized situations, a different variant was made (ok, there was another reason but that's a bit technical). At that time, I had already adapted itemize to work a bit better with bTABLE and starttabulate (nesting, trial mode etc), think of \bTABLE \bTR \bTD \startitemize[a] \startitem \im{\sqrt{\frac{1}{x^4}}} \stopitem \startitem \startitemize[n] \startitem \im{\sqrt{\frac{1}{x^4}}} \stopitem \startitem \im{\sqrt{\frac{1}{x^4}}} \stopitem \stopitemize \stopitem \startitem \im{\sqrt{\frac{1}{x^4}}} \stopitem \stopitemize \eTD \eTR \eTABLE or with tabulate \startitemize[n] \starttabulate[||k2|] \NC \startitem test \stopitem \NC \startitem test \stopitem \NC \NR \NC \startitem test \stopitem \NC \startitem test \stopitem \NC \NR \stoptabulate \stopitemize so basically inside these tables items can be dealt with. Don't wonder too much how this translates into structure. So, back the columns, a logical next step was to add tabulated columns to itemize: \startitemizetable[n,four] \dorecurse{10}{ \startitem \im{\sqrt{\frac{1}{x^4}}} \stopitem \startitem \im{\sqrt{x^5}} \stopitem \startitem \im{\frac{x^5}{x^5}} \stopitem } \stopitemizetable or with \defineitemgroup[xxxx] because every itemgroup also gets an additional pair of commands defined. \startxxxxtable[n,four][inbetween={\blank[big]}] \dorecurse{10}{ \startitem \im{\sqrt{1/x}} \stopitem \startitem \im{\sqrt{\frac{2}{x}}} \stopitem \startitem \im{\frac{3}{x}} \stopitem } \startitem \im{\sqrt{\frac{1}{x^4}}} \stopitem \startitem \im{\sqrt{x^5}} \stopitem \stopxxxxtable etc etc. The distance can be set with columndistance and vertical spacing with inbetween. This kind of columnizing has the advantage that esp with math that has different heights all aligns rather well. A limitation is that we number horizontally but that actually makes sense when we cross pages (I might cook up a transposed numbering but it's not entirely trivial). The first one who uses this other than Mikael is invited to wikify it. Hans ps. The page columns also have some improvements but that's for next month. ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

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. Thanks in advance, Xavier PS: I use context version:mtx-context | ConTeXt Process Management 1.04 mtx-context | mtx-context | main context file: /usr/share/texmf-dist/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2023.03.10 12:15 mtx-context | main context file: /usr/share/texmf-dist/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2023.03.10 12:15

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
