Character alignment in math mode

> why use math here? It was to avoid oldstyle figures that I use by default. But finally it's better to use oldstyle figures even in tables. Another question about fonts. Is there a way to define a conditional mathcommand based on the current alternative style? For instance, in the following example I would like to keep the bold effect but with adaptation to the local alternative style (in text mode, when the local alternative style is \tf I would like the mathcommand to be \bf, when it is \it I would like \bi, when it is \bf I would like \bf and when it is \bi I would like still \bi): \starttext \definemathcommand[cool]{{\bfmath cool}} text mode normal: \cool\crlf text mode italic: {\it \cool}\crlf text mode bold: {\bf \cool}\crlf text mode bolditalic: {\bi \cool}\crlf \stoptext

database module: the first letter is lost
by Michael Green 25 Jun '14

This appears to be the same as the problem Peter Münster found with the letter module \usemodule[database] \defineseparatedlist[MyTable] [separator=tab, before=\bTABLE,after=\eTABLE, first=\bTR,last=\eTR, left=\bTD,right=\eTD] \starttext The first letter of “Cell” is lost. \startseparatedlist[MyTable] Cell 1 Cell 2 \stopseparatedlist With an extra return, “Cell” is intact. \startseparatedlist[MyTable] Cell 1 Cell 2 \stopseparatedlist \stoptext

First letter lost possible cause: \grabbfferdata
by Rik Kabel 25 Jun '14

25 Jun '14

Recently there have been reports of the first letter of a line of text being lost in the database and letter modules. I tracked down what appears to be the same problem and developed a work-around. The problem appears to be with the \grabbufferdata command. Something has changed in the way it works, and it now swallows the first token of the buffer that it grabs. It may also show up with other commands, but this is the only one I have found in my projects. If you have code with this command, a workaround is to insert \ignorespaces after it. I have no idea why this helps. If you do not have the code (if it is in somebody else's module), then using a blank line or dummy argument or \relax after the command that calls the code with \grabbufferdata may help. The following code shows the issues and these workarounds. % macros=mkvi \starttexdefinition unexpanded startNoIgnore \begingroup \dostartNoIgnore \stoptexdefinition \starttexdefinition dostartNoIgnore \grabbufferdata[Test][startNoIgnore][stopTest] \stoptexdefinition \starttexdefinition unexpanded startWithIgnore \begingroup \dostartWithIgnore \stoptexdefinition \starttexdefinition dostartWithIgnore \grabbufferdata[Test][startWithIgnore][stopTest] \ignorespaces \stoptexdefinition \starttexdefinition stopTest \getbufferdata[Test] \endgroup \stoptexdefinition \define\TestText {\qquad If you can read this the first token was not swallowed.} \starttext \subject{Test without \tex{ignorespaces}} First, the problem: \startNoIgnore\TestText\stopTest And the same with \type{{}} \startWithIgnore{}\TestText\stopTest Workaround with \tex{relax} \startNoIgnore\relax\TestText\stopTest Workaround with blank line \startNoIgnore \TestText\stopTest \subject{Test with \tex{ignorespaces}} This now works: \startWithIgnore\TestText\stopTest And the same with \type{{}} \startWithIgnore{}\TestText\stopTest And the same with \tex{relax} \startWithIgnore\relax\TestText\stopTest And the same with a blank line after the opening \startWithIgnore \TestText\stopTest \stoptext -- Rik Kabel

issues with list items
by Pablo Rodriguez 25 Jun '14

25 Jun '14

Dear list, I have the following sample (compiled http://www.ousia.tk/list-items.pdf#page=1) \showframe\showgrid \setupbodyfont[pagella,15pt] \starttext \chapter{Chapter title} \section{Section title} \dorecurse{11}{\dorecurse{10}{Sentence. }\par} \startitemize \dorecurse{2}{\item This is an item.} \item This is an item\footnote{This is a footnote.}. \stopitemize \dorecurse{50}{These are other sentences. } \stoptext The footnote moves the whole list to the second page. If I remove the footnote and not the item, the whole list fits in the first page (http://www.ousia.tk/list-items.pdf#page=3) Sorry, but as far as I can understand, I’m afraid this is a bug. ConTeXt is handling list items themselves with widows and orphan rules. Not the lines they contain, but the items themselves. I understand that ConTeXt avoids widow and orphan lines within list items. But it makes no sense (at least, to me) to avoid widow and orphan list items. Could someone confirm the bug or explain me what I’m missing? Many thanks for your help, Pablo -- http://www.ousia.tk

> \let\Test\fontstylesuffix > a bit different output Thank you Hans. > The command \mathgreekitalic can only be used in math mode, when you want a italic alpha in text mode you need a font which has greek characters (e.g. Gentium). Okay Wolfgang, I thought Latin Modern also had greek characters, but apparently not. So in math mode which font is used by default if it is not Latin Modern greek?

Problem in natural tables with nc= and alignmentcharacter
by Rik Kabel 25 Jun '14

25 Jun '14

When a wide-ish column precedes a character-aligned column and a column span is in place, the table is set improperly. With the following example, the first two columns overlap. When the first column is moved to the right side of the table there is no issue. When the setup line is removed, there is no issue. When the long entry in column is shortened, there is no issue. When the column span is removed and another cell added to that row, there is no issue. The problem occurs when the span is applied to the first two or the last two columns in the example. TL14 handles this correctly. It fails with the 20140622 beta. \starttext \bTABLE \setupTABLE[c][3][alignmentcharacter={.},aligncharacter=yes] \bTABLEbody \bTR \bTC AAA\eTC \bTC[nc=2] Location\eTC \eTR \bTR \bTC AAA Longish entry\eTC \bTC Figure\eTC \bTC 1.12\eTC \eTR \bTR \bTC AAA\eTC \bTC Table\eTC \bTC 10.8\eTC \eTR \eTABLEbody \eTABLE \stoptext -- Rik Kabel

> You can access the current font alternative with the \fontalternative command Thanks Wolfgang, that was exactly the command I was looking for! A last question: how can one get italic greek in TEXT MODE? The following code displays upright greek. \starttext \mathgreekitalic \alpha \stoptext

How can one use character alignment in math mode? (I am using the last stable ConTeXt version — 2014.05.21.) \starttext \setupTABLE[column][first][alignmentcharacter={,}, aligncharacter=yes, align=middle] Figures in text mode get aligned: \startTABLE \NC 0,0 \NC \NR \NC 0,00 \NC \NR \NC 0,000 \NC \NR \stopTABLE But figures in math mode do not get aligned: \startTABLE \NC $0,0$ \NC \NR \NC $0,00$ \NC \NR \NC $0,000$ \NC \NR \stopTABLE \stoptext Best regards.
