Spacing around integrals
by Aditya Mahajan 19 Sep '12

19 Sep '12

Hi, The spacing around the integrals is wrong in the current version when using latin modern or xits (but correct when using cambria or euler). Is this due to wrong parameters in the font, or something wrong at the ConTeXt end? Minimal example: \setupbodyfont[xits] \setupmathematics[integral=nolimits] \starttext \startformula \int_{-∞}^{∞} f(t)dt \stopformula \stoptext Aditya

Publicationlist
by Eidenbenz Michael 19 Sep '12

19 Sep '12

Hello list, is there a way to setup the layout of the publicationlist? I would like to add a blank line after every entry. I already created my own style file to alter the layout of some publications but don't know where to change the list. best michael

List of macro-generating macro (was: Ctx: list of commands)
by Sietse Brouwer 19 Sep '12

19 Sep '12

Hi Hans, > quite some commands are generated so we would still miss a lot For any now-or-future documentation project, it will be useful to have a list of macros that generate (user-facing) macros. * We could use it to modify these macros so that they report to a table the macros they create. * We could use it to simply find the places these factory macros are used, when constructing our list of commands * We could use it when looking for the source of an indirectly-defined command --- useful when writing options documentation. So, for starters: below is a tab-separated list of various \install*handler commands (and their frequency in the *.mk* sources). I hope gmail doesn't mangle the formatting too badly. Could you note, for each one, * whether it is a top-level macro or simply a helper routine * If it is a top-level macro, whether it creates user-facing commands always, sometimes, or never? (Working definition of top-level macros vs helper routines: macros that you yourself call directly when writing functionality, versus routines that you once split off to structure the code, and that only gets called by some other macro.)

Ctx: list of commands
by Procházka Lukáš Ing. - Pontex s. r. o. 18 Sep '12

18 Sep '12

Hello, 1) is there a Ctx command/switch which would generate list of all current ConTeXt commands? E.g. " context --list-of-commands > Cmds.txt " to produce ---- Cmds.txt \startCAP \stopCAP \startCap \stopCap ... \writetoregister ---- 2) The directory "c:\Ctx-Beta\tex\texmf-context\context\data\textpad" is empty (by default?). Its content: - is filled when context.exe is launched with a command/switch (if so, which command?), or - is filled when a newer version of ConTeXt is downloaded (if so, which "extras" - like "first-setup.bat --extras=all --modules=all" - should be specified to fill the directory)? TIA. Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

Bibliography, unicode strings, @ELECTRONIC, sorting and bibtex
by Marco Patzer 18 Sep '12

18 Sep '12

Hi, I have some questions regarding the bibliography. 1) The style files bibl-ams.tex, bibl-ssa.tex, etc contain strings like ``, ~. This does not make sense to me. The `` ends up like that in the output and the tilde might interfere with the \asciimode setting. Wouldn't it be better to use the proper Unicode glyphs (U+201C, U+00A0, etc.) nowadays? I assume the files are old MkII files and not being updated since. Example: \setupbibtex [database=sample] \setuppublications [alternative=ssa] \starttext \cite[hh2010a] \cite[Eijkhout1991] \cite[hh2010] \placepublications [criterium=cite] \stoptext 2) The @ELECTRONIC type does not work (already mentioned in the wiki). It does not show up in the references list. I guess no one bothered adding them and it's up to me to add the corresponding entries. Maybe someone has already prepared a working file for the APA style? 3) How to sort the bibliography by author? According to the bib manual I expected this to work: \setupbibtex [database=sample] \setuppublications [alternative=apa, criterium=cite, sort=author] \starttext \cite[hh2010a] \cite[Eijkhout1991] \placepublications \stoptext 4) \completepublications produces an empty page. Is that intended? \setupbibtex [database=sample] \setuppublications [alternative=ssa, criterium=cite] \starttext \cite[hh2010a] \completepublications \stoptext 5) (side question) What is BibTeX used for in ConTeXt? As far as I can see, it reads the .bib database and generates a .bbl file which then is read in by ConTeXt. Why do we need an external tool for this? Why does ConTeXt not read in the .bib database and directly save it as a Lua table? Marco

[.tuc] oddity when storing a table

Hi all, I can’t explain the following behavior of the .tuc writer. When passed a nested hash, context fails on the second pass if the array part of the first nesting depth is empty: ······································································· %% the commented lines work \startluacode job.variables.tobesaved.foo = { bar = { } } -- job.variables.tobesaved.foo = { "works now", bar = { } } -- job.variables.tobesaved.foo = { bar = "works too" } \stopluacode \starttext foo \stoptext ······································································· I get this error: ······································································· !

Exploring the Lua innards of ConTeXt: showtable
by Sietse Brouwer 17 Sep '12

17 Sep '12

Hi all, ConTeXt mkiv stores all sorts of things in Lua tables, but 'what goes where' does not tend to be documented. So here is a function to print out a table's contents to get something like the following excerpt. The excerpt is from the output of `userdata.showtable(structures.lists)` in a document with three \placefigures and one \placeformula. Note the reference in T.cached.1.references.reference, and the caption in T.cached.1.titledata.title (T stands for the table yone passed to showtables); and note how the tables of figures 2 and 3 are not printed, because they follow the same pattern as table 1. (You can tell showtable to print everything, natch.) T.addto : function: 0xa4c8818 T.analyze : function: 0xb1c27b0 T.cached : table: 0xb1c2240 T.cached.1 : table: 0xc3f7b18 T.cached.1.metadata : table: 0xc3f7d58 T.cached.1.metadata.kind : float T.cached.1.metadata.name : figure T.cached.1.prefixdata : table: 0xc3f7c68 T.cached.1.prefixdata.connector : . T.cached.1.prefixdata.prefix : no T.cached.1.references : table: 0xc3f7ba8 T.cached.1.references.reference : ref:asdf T.cached.1.titledata : table: 0xc3f7b40 T.cached.1.titledata.title : caption 1 T.cached.2 : table: 0xc467bb8 (like T.cached.1) T.cached.3 : table: 0xc4731a8 (like T.cached.1) T.cached.4 : table: 0xc47c988 T.cached.4.metadata : table: 0xc47d628 T.cached.4.metadata.kind : formula T.cached.4.metadata.name : formula (You can't see it in this e-mail, but the colons of entries in the same subtable nicely line up with each other.) Usage: put showtable.lua in your working directory and run the following code: \starttext % \placefigure[][ref:asdf]{caption 1}{picture 1} \startluacode require('showtable') userdata.showtable(structures.lists) \stopluacode \stoptext Extra options can be passed as part of an options table. (This allows overriding one option without respecifying the others.) userdata.showtable( structures.lists, { everything=true, -- descend even into similar-looking siblings tablename='S.L' } ) Output is printed to the terminal, alas, because I couldn't discover how to print to the log. Anybody know anything about this? Hopefully this may be useful to someone, next time they they're hunting for something in the bowels of ConTeXt. Interesting tables to look at: * userdata.showtable(commands) contains a great miscellanea of helper commands * userdata.showtable(context) also contains a great miscellanea of commands * userdata.showtable(tex) seems to show lua access functions to some plain tex stuff * userdata.showtable(lxml) gives a list of lxml-related functions Cheers, Sietse

Bug in xits font? No widehat shows up
by Otared Kavian 17 Sep '12

17 Sep '12

Dear Khaled, dear Hans, I noticed that when using xits fonts the command \widehat is ignored (though \hat gives the expected result). Minimal example %%% begin example \setupbodyfont[xits,11pt] \starttext By definition we set ${\widehat \phi}(\xi) := {\cal F}(\phi)(\xi)$ that is \startformula {\hat \phi}(\xi) = \widehat{\phi}(\xi) = {\widehat \phi}(\xi) := {\cal F}(\phi)(\xi) := (2\pi)^{-N/2}\int_{{\Bbb R}^N}{\rm e}^{-{\rm i}\xi\cdot x}\phi(x) dx. \stopformula \stoptext %%% end example This bug report concerns mkiv version ConTeXt ver: 2012.09.16 23:18 MKIV fmt: 2012.9.17. However in older versions the same problem exists. I don't know whether this is a bug in mkiv or in xits fonts. Best regards: OK

international documents
by Pavel Dohnal 17 Sep '12

17 Sep '12

Hello, I am creating script which generates context source from database data. Then converts context to pdf and sends it to user. Problem is that users enter international texts into database and some characters are not present in final pdf. Here is my minimal example: %interface=en translate-file=utf-8 \enableregime[utf] \starttext This is in Japan: 日本, 神奈川県藤沢市藤沢７５ \stoptext Now I run: context file.tex But japaneese character are missing in final pdf. You can see in attached file. Is there a way how to create documents which can be writen in any international language? Thanks for your help Pavel Dohnal
