cont-new.mkiv and \everymathematics
by Rogers, Michael K 21 Jan '24

21 Jan '24

Hi all, In writing class notes, I frequently make one-letter macros for formatted symbols, such \v and \w for vectors. Generally speaking, one-letter names for function/macros/variables is frowned upon in programming, but I find this localized use very convenient. In cont-new.mkiv, one finds definitions of \t and \w (via \let) appended to \everymathematics, which overwrites my definition of \w every time TeX enters math mode. I can fix this by appending my definition to \everymathematics. The inefficiency seems minor, and I can live with it. I have a question and a couple of points: 1. Is there a better way than adding the definition to \everymathematics? 2. I don’t think these definitions should be in ConTeXt. Let users add them if they wish. Or add a ‘useshortcuts’ option to \setupmathematics. 3. \t and \w are undocumented, \mathword is undocumented, and it took me a while to track down the bug it created for me. In particular, they overwrote my definition only in math mode, and “\show\w” did not work in math mode. Frustrating. I could add a wikipage, I suppose, but I’m not proud of the extent of my knowledge: “\mathword{word} typesets “word” in math mode in a normal text font, somewhat like \text{word}, and \w is an abbreviation of it that is added to \everymathematics on startup.” Thank you very much, Michael

Why LuaMetaTex is so slow?
by Shiv Shankar Dayal 19 Jan '24

19 Jan '24

I can process TeXBook in almost an instant using PDFTeX which is about 450+ pages but my math book takes around 30 seconds averaging ~40 pages/second. Why LuaMetaTeX is so slow? How can I speed it up? -- Respect, Shiv Shankar Dayal

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

Re: Math alignment issue

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. I am using ConTeXt LMTX version 2024.01.08 on MacOS 11.7.10.

How to obtain older versions of LMTX?
by Otared Kavian 18 Jan '24

18 Jan '24

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
