Setting up protrusion, side-effects
by Martin Althoff 28 Jul '10

28 Jul '10

When setting up protrusion, I noticed it "disappearing" despite being defined/setup. In a text, when I changed the font from Palatino to Sabon (with \setupbodyfont[sabon]), protrusion stopped working. Changing back to palatino, with nothing else changed, protrusion appeared again. Note: getting the latest minimals update did not change anything: context: version: 2010.07.27 16:30, LuaTeX, Version beta-0.60.2-2010070117 on OSX 10.6.4 The following test file showed that if the \setupbodyfont takes place before \definefontfeature and \setupalign, protrusion fails completely. In the example 1 below it fails. Disabling the top \setupbodyfont and enabling the bottom \setupbodyfont gets it to work. However, it will fail for both Palatino and Sabon! I could not create an example for one font working and the other not. Is the order of declaration important? That would be unusual in context by what I have seen so far. Am I missing something? Example 1: \setupbodyfont[palatino] % protusion Einstellungen \definefontfeature [default][default][protrusion=quality,expansion=quality] \setupalign[hz,hanging] %\setupbodyfont[palatino] \showframe \starttext \input tufte \stoptext Possibly related is the following. Executing \showbodyfont for palatino with protrusion enabled messes up the text following it. The same done with Sabon is no problem. The Example 2 below illustrates the problem. I have attached the PDF to show the output. While this obviously not a real problem, as the \showbodyfont won't be in a final output, it might hint at an underlying problem, possibly related to the above problem. Example 2: % Set up protusion \definefontfeature [default][default][protrusion=quality,expansion=quality] \setupalign[hz,hanging] \setupbodyfont[palatino,12pt] \showframe \starttext \showbodyfont \input tufte \switchtobodyfont[sabon,12pt] \showbodyfont \input tufte \stoptext

help with startformulas and startalign
by Julian Becker 27 Jul '10

27 Jul '10

Hi everybody, I'm new to ConTeXt and need a little expert help. When I'm running the following 'test.tex' file ------------------------ \starttext \placeformula \startformulas \startformula \startalign \NC A \NC = B \NR[+] \NC C \NC = D \NR[+] \stopalign \stopformula \startformula E \stopformula \stopformulas \stoptext ------------------ I get the following errors: systems : begin file test.tex at line 1 ! Missing $$ inserted. <to be read again> \Ustopdisplaymath \stopformula ->\normalstopformula \egroup \Ustopmath \hss <argument> ...= D \NR [+] \stopalign \stopformula \startformula E \stopformula \dostartformulas ...la \egroup \Ustopmath \hss }#2 \egroup \stopdisplaymath \... l.12 \stopformulas ! You can't use `\Ustopdisplaymath' in horizontal mode pages > flushing realpage 1, userpage 1, subpage 1 systems : end file test.tex at line 14 Does anybody know how to do this right? Startformulas itself works allright, if I leave out the alignment part. I also tried startmathalignment instead, but it gave the same errors. Best regards, Julian

LuaTeX & printf() function ?
by Vnpenguin 23 Jul '10

23 Jul '10

Hi, Here is my test: =================================================== \setuppapersize[A4][A4] \usetypescript[postscript] \setupbodyfont[palatino,12pt] \starttext \startformula K = \frac{\sigma_1}{\sigma_2} = \frac{355}{14}= \ctxlua{tex.print(355/14)} \stopformula \stoptext =================================================== It works well and give me result = 25,357142857143. In order to obtain 2 decimal number I tried: \startformula K = \frac{\sigma_1}{\sigma_2} = \frac{355}{14}= \ctxlua{tex.printf("%0.2f",355/14)} \stopformula But it does not work. Here is the error: tex.printf("\doplaceformulanumber \stopdisplaymath \global \let \gdef \ETC. ! File ended while scanning text of \zerocount. <inserted text> } <*> ./test-lua.tex ? Another try: \startformula K = \frac{\sigma_1}{\sigma_2} = \frac{355}{14}= \ctxlua{tex.print(string.format("%0.2f",355/14))} \stopformula gives me the same error. So is there really a function printf() in LuaTeX engine ? Thanks
