Autogenerating a module's documentation
by Mohammad Hossein Bateni 01 May '16

01 May '16

Hello list, Has anyone managed to generate documentation for lua files recently? According to wiki/Module <http://wiki.contextgarden.net/Modules>, something like the following should work: context --ctx=x-ldx core-con.lua But it only produces core-con.lua.prep and not the PDF file. In fact, it seems to work on the prep file and compile a core-con.lua.prep.prep which escapes even the XML tags of the prep file. Probably some switch changed and the ctx file was not updated, so it just doesn't know how to deal with the prep file properly? On the other hand, the command to get PDF documentation out of TeX files does work and produces (albeit with some errors at times) the final documentation. context --ctx=s-mod core-con.mkiv Thanks! —MHB

RTL \definedescriptions
by Mohammad Hossein Bateni 01 May '16

Hello Hans and Wolfgang, I tried different options in \definedescription and compared LTR and RTL behavior. There are certain inconsistencies/bugs in the RTL setting. Attached you can see a TeX file and the resulting PDF, trying different options. The first two pages consider different parameters in the LTR setting and then the same come in the RTL environment. In the following I use alt instead of alternative. Here are the issues I noticed: 1) Why isn't the head text consistently mirrored in the RTL environment? It happens only in alt=serried. 2) Option hang=2 produces a strange result for RTL. The hanging part appears on the opposite side of the head text, which somehow pushes the head text outside the text area. 3) Option alt=top for RTL still puts the head text on the left-hand side. 4) I expect the LTR and RTL versions of the same settings to mirror one another, but they do not. Although LTR/alt=left and RTL/alt=right look pretty similar (and so do LTR/alt=right and RTL/alt=left), but these pairs do not mirror one another. In particular, there is some space to the right of the head text in LTR/alt=right, while there is none to the left of LTR/alt=left. The same thing shows in the margin alternatives where the distance between the head text and the body is different in RTL and LTR. —MHB

Dear list, I have the following sample, \setuppapersize[A5][A4, landscape] \setuparranging[2UP] \setuplayout [backspace=0pt, topspace=0pt, width=middle, height=middle, location=middle, header=0pt, footer=0pt] \startbuffer[hola] \mainlanguage[es] \starttext \dorecurse{32}{\input cervantes-es\par} \stoptext \stopbuffer \starttext \typesetbuffer[hola] %~ \insertpages[{\typesetbuffer[hola]}][width=Opt] \stoptext Is there any way to make the commented \insertpages command work? Or is there any way to force the PDF file name in \typesetbuffer? Many thanks for your help, Pablo -- http://www.ousia.tk

Strange bug in the latest version of ConTeXt
by Jaroslav Hajtmar 01 May '16

01 May '16

Hello ConTeXist. I have just installed the latest version of ConTeXt standalone. When I compiled an my old source code, I received an error: ! You can't use `\Ustopmath' in restricted horizontal mode! You can't use `\Ustopmath' in restricted horizontal mode! You can't use `\Ustartmath' in restricted horizontal mode! Inline math should end with \Ustopmath This strange error is caused something in my extensive library for handling CSV files. I'm not sure why, because in library I am not use with any mathematical mode. I am sorry, but at this moment I am not able to reveal the mistake to be able make a minimal example. Some of the older versions (not necessarily penultimate) worked without problems. Is there someone who help me start look from which point look for a mistake in my code library? Thanks for the information. Jaroslav Hajtmar

Problems with ttc-fonts
by Ulrike Fischer 01 May '16

01 May '16

I was playing with the addfeature handler mentioned here https://mailman.ntg.nl/pipermail/ntg-context/2016/083952.html and run into a problem with ttc-fonts: \starttext \directlua{ fonts.handlers.otf.addfeature { name = "oneb", { type = "substitution", data = { ["1"] = "period", }, }, "feature test", } } \font\test= name:LatinModernRoman:+oneb \test 1234567890 \font\test= name:cambria:+oneb \test 1234567890 \stoptext This gives: .234567890 p234567890 So with latin modern it works fine, while with cambria the first letter of the substituation is used. The used fonts are: filename=lmroman10-bold.otf filetype=otf format=otf foundname=D:/context-minimals/context/tex/texmf/fonts/opentype/public/lm/lmroman10-bold.otf usedmethod=database filename=c:/windows/fonts/cambria.ttc format=ttc foundname=c:/windows/fonts/cambria.ttc usedmethod=direct (I have no idea why the bold version of lm is used, but I don't care now) Looking at the tma I see one difference between both fonts: glyphs in cambria have no "name". A typical entry looks like this [46]={ ["boundingbox"]={ 109, 0, 311, 232 }, ["index"]=484, ["unicode"]=46, ["width"]=420, }, while with latin modern it looks like this: [46]={ ["boundingbox"]={ 81, 0, 237, 156 }, ["index"]=88, ["name"]="period", ["unicode"]=46, ["width"]=319, }, Is is normal that glyph of ttc-fonts have no name data? If yes how should one do substituations in such fonts? -- Ulrike Fischer http://www.troubleshooting-tex.de/
