LuaMetaTeX code
by Shiv Shankar Dayal 19 Jan '24

19 Jan '24

Dear Hans, I saw the C code of LuaMetaTeX and I saw a lot of gotos which is not good coding practice. These potions of code which have goto should be refactored. I am a C programmer, but I know very little of TeX. If you can point me towards where should I start for TeX(perhaps TeX Book or TeX for the Impatient), I can help with refactoring of code to make is more efficient/easier. -- Respect, Shiv Shankar Dayal

scaling tweaked fonts
by Pablo Rodriguez 18 Jan '24

18 Jan '24

Hi Hans, I have the following sample which behaves differently after latest from 2023.09.26 18:19: \definetweakedfont[wider][xscale=1075] \starttext \startTEXpage[align=center] \contextversion\\ \wider \contextversion \stopTEXpage \stoptext Up to that version, no scaling was 1000, after that one no scaling became 1. This should be the reason behind my previous issue about too large sizes in the first latest from 2024 (https://mailman.ntg.nl/archives/list/ntg-context@ntg.nl/thread/JVB7AWJE53NW…) I just want to confirm that this change was intended. Many thanks for your help, Pablo

How to Create Asymmetrical Continuous Columns in ConTeXt?
by seyal.zavira＠gmail.com 18 Jan '24

18 Jan '24

Hi all, I have a lengthy text that I wish to seamlessly incorporate using the \input{mytext} command in ConTeXt. Additionally, I aim to present it in asymmetrical continuous columns, where the text flows over several pages. I have tried paragraphs and columns, but in paragraphs, I can't flow text across several pages without manually breaking it, and in columns, I haven't found a way to implement asymmetric columns. How can I achieve this layout in ConTeXt? this is a MWE but it does not work properly: \definecolumnset[mymixedcolumn][n=2] \setupcolumnset[mymixedcolumn:1][width=4cm] \setupcolumnset[mymixedcolumn:2][width=7cm] \starttext \startcolumnset[mymixedcolumn] \dorecurse{5}{ \input{knuth} } \stopcolumnset \stoptext also is there a mechanism to automatically continue text between desired frames? For example, is there a way to write a function that, if the text reaches the end of the line and there is not enough space for another line in that frame, it continues the text in another frame that is already specified? in other word How do you make text flow to another part of a page? Thanks in advance. Best regards, Seyal

Is there a (hidden) option that allows for changing the font color of external included pdfs \copypages[file.pdf][color=blue] does not work as intended ;-) .Floris

Hi Mikael, Thank you for your reply. When I typeset the example you sent me, that is %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 I get something different than the PDF you sent me: the formulas run into the text just above them, as you can see in the attached PDF.

Hi all, In order to circumvent a bug in the latest versions (2023-09-26 and 2024-01-08) of LMTX regarding math alignments, I am trying to get an older version of LMTX (from before September 2023) for MacOS ARM. Does any one know how to proceed? Thanks in advance. Best regards: Otared

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
