odd and even test: incorrect behavior on the first two lines
by stdin | Alexandre Leray 07 Sep '12

07 Sep '12

Hi, I'm trying to make the content of an environment behave differently weither it appears on a right page or on a left page. It works mainly, except that with the following code, from the second page, the two first lines of subsequent pages don't show the expected behavior. \setuppagenumbering[alternative=doublesided] \definestartstop[foo][ before={\doifrightpageelse{(right)}{(left)}}, ] \starttext \dorecurse{100}{ \startfoo hello world\par \stopfoo } \stoptext Is it a known problem? How can one fix this? Thanks, Alex -- Alexandre Leray media & graphic design http://stdin.fr | http://osp.constantvzw.org/ rue Gallaitstraat 80 1030 Bruxelles +32 (0)4 87 04 70 30

Tryng to download manual sources. This command doesn't work: svn co svn://ctx.pragma-ade.nl/manuals context from directory /usr/local/src, and signed on as root. I keep getting "connection timed out" Is there something wrong with the above command? -- John Culleton Free list of books for self-publishers: http://wexfordpress.net/shortlist.html Police Procedural and Expose: "Death Wore Black" "Create Book Covers with Scribus" http://www.booklocker.com/books/4055.html

Strange behavior of references when using annotation-module
by Dominik Leopold Forkert 05 Sep '12

05 Sep '12

Hello, I use the latest mkiv beta. When using the annotation module, the output of\in[...] misses a separation dot between chapter and formula number, e.g. "31" instead of "3.1". When I omit the annotation module, there is no chapter number at all in the \in[...] reference! A minimal example of the problem: \usemodule[annotation] \setupformulae[way=bychapter,prefixsegments=chapter,prefixstopper=.] \starttext \chapter{A chapter} \section{A section} \placeformula[OK] \startformula a+b=c \stopformula In \in[OK] we noticed blabla ... \stoptext Another problem is that \smash seems not to work properly for me! Both problems do not occur at all in mkii! Best regards, Dominik

Automatic margin floats using the criterium parameter
by Marco Patzer 05 Sep '12

05 Sep '12

Hi, I am working on some float placement code for a project. To not reinvent the wheel I like to know what is currently possible in ConTeXt. Small floats should be placed in the margin and bigger ones centred in the text. Captions always go into the margin. That is the idea. The key to automate this seems to be the \setupfloat[criterium=…] parameter. Details: 1) Captions always in the margin 2) Captions left aligned 3) Figures smaller or equal \marginwidth go into the outer margin 4) Margin figures are aligned to the inner side of the margin 5) Margin figure captions underneath the figure 6) Figures wider than the margin go centred into the text 7) Text figure captions top aligned I got almost everything working. A minimal example is attached. Problems: Mf 1-2 are placed correctly. Problematic are Mf 3-4. The caption is not placed in the margin because of the \setupcaptions [mf] [location=bottom] setting for margin figures. Another thing is the weird alignment of Mf 3-4, I expect the figures to be centred. The reason is the following setting. \setupfloat [mf] [location=inner] If uncommented, the alignment of the margin figures is wrong. Figure 1-2 are examples of how it should look like. I could come up with a hackish solution on my own but maybe someone has an idea how to achieve this with built-in support. Marco

TeX expansion within lua
by Marco Patzer 05 Sep '12

05 Sep '12

Hi, please have a look at the following example: \starttext \def\cmd{% \def\mymacro{Foobar} \newtoks\mytoks \mytoks={mytoks}} \startluacode context.cmd() context.mymacro() -- this fails -- context(tex.toks.mytoks) \stopluacode -- this works \startluacode context(tex.toks.mytoks) \stopluacode \stoptext Why does the first call to tex.toks.mytoks fail? Apparently the luacode environment has to be closed for cmd to be expanded. I guess that the call to mymacro() succeeds is a quirk due to the face that the macro is expanded later, in contrast to tokens, dimens and counters. Is there a command I can use within Lua to expand a macro immediately or to expand the pending macros to be able to access the values like the token register in the example? Another question which is related: Is there a way to access the contents of the macro from within Lua like counters and token registers? \starttext \newtoks\mytoks \mytoks={Foobar} \startluacode local tok = tex.toks.mytoks -- something like this is what I have in mind -- local mac = tex.macros.somemacro \stopluacode \stoptext I am just interested in a text string, not a box with typeset material. I guess that's more difficult, since macros are expanded and not just simply read. Marco

Lua conditionals fail inside \starttexdefinition
by Marco Patzer 05 Sep '12

05 Sep '12

Hi, I discovered strange behaviour concerning Lua conditionals within texdefinitions. ConTeXt complains: 'then' expected near 'thenelseend'. I guess it has something to do with how the content of a texdefinitions is grabbed. Seems like a bug or is this by design? % This works fine \def\mycmd{% \startluacode if true then else end \stopluacode} % This one fails % \starttexdefinition mycmd % \startluacode % if true then % else % end % \stopluacode % \stoptexdefinition \startluacode userdata = userdata or { } function userdata.myfun() if true then else end end \stopluacode % This also works fine \starttexdefinition mycmd \luacode{userdata.myfun()} \stoptexdefinition \mycmd Marco

Setting options for every n-th row in natural TABLEs
by Aditya Mahajan 05 Sep '12

05 Sep '12

Hi, On Edward Tufte's website, there is a discussion on zebra coloring in tables[1]. One of the suggestion is to add a horizontal rule after every third line or shade three lines with one background color and the remaining three with another background color. Is there an easy way to do this with natural TABLEs? I can do something like: \setupTABLE[row][1,2,3][background=color, backgroundcolor=gray] \setupTABLE[row][7,8,9][background=color, backgroundcolor=gray] but it requires knowing the number of lines in advance.

\startluacode and macro names with underscores
by Marco Patzer 04 Sep '12

04 Sep '12

Hi, the luacode environment chokes on macro names with underscores. Example: \starttext \unprotect \def\number_two{two} \startluacode userdata = userdata or { } function userdata.number_one() context("one") end -- works userdata.number_one() -- fails -- context.number_two() -- workaround tex.print("\\number_two") \stopluacode \protect \stoptext Why is that and what can be done to access underscored macros in the usual way? I guess it's some catcode change from the function that prints into the TeX stream. Marco

Component: \product, \project
by Procházka Lukáš Ing. - Pontex s. r. o. 04 Sep '12

04 Sep '12

Hello, when looking at http://wiki.contextgarden.net/Project_structure - - why \product and/or \project specification is used in the COMPONENT in the example, or why is it supposed or even required to use in components? I imagined that component doesn't need to know in which project/product is used, even when in may be intended to more projects/products. So does it mean I would have to enumerate all projects/products in which the component is to be used? Or can be \product and/or \project specification omitted in the component?
