Deep down we have (spac-ver) this: \definevspacing[preference][penalty:-500] % goodbreak \definevspacing[samepage] [penalty:10000] % nobreak \definevspacing[max] [category:1] \definevspacing[force] [category:2] \definevspacing[disable] [category:5] \definevspacing[nowhite] [category:6] \definevspacing[back] [category:7] % together [category:8] \definevspacing[overlay] [category:9] \definevspacing[always] [category:0] \definevspacing[weak] [order:0] \definevspacing[strong] [order:100] so we can have weights and so. However, in practice the problem is that when combining different mechanisms their spacing settings might not be tuned to each other. I will extend this mechanism when we have a bit more control over some of the lists involved. It's no big deal to set up something for an index, but it needs thinking about how to deal with worst case scenarios and these will happen for sure and you don't want to end up with a sequence of entries two pages height running of a page, certainly not in a fully automated workflow. It is on the to-be-loked-into-list, but as all things, it has to fit into my agenda (read: to be done in what's left of my free time). I also have to make sure then it does not mess up existing files. For the moment playing with the before/after keys is the way to go.

Exporting auto-generated Index/Registers as ConTeXt source
by Jan Tosovsky 28 Jun '14

28 Jun '14

Dear All, I'd like to tweak the auto-generated Index. Is there any possibility to export it as the ConTeXt source, modify it and then include instead of auto-generated Index? Thanks, Jan

In XSL-FO all these can be set quite easily using keep-with-next/previous rules placed on first and last items. The complexity behind is left to XSL-FO processors. primary-01 % keep-with-previous & keep-with-next (rules 1 & 2) primary-02 secondary-01 % keep-with-previous & keep-with-next (rules 1 & 2) secondary-02 secondary-03 secondary-04 % keep-with-previous (rule 3) primary-03 % keep-with-previous (rule 3) The only natural break is between secondaries: primary-01 primary-02 secondary-01 secondary-02 -------- ( break ) ------- secondary-03 secondary-04 primary-03 In case of three secondaries all is kept together and moved to the next page as a whole: primary-01 primary-02 secondary-01 secondary-03 secondary-04 primary-03 Only if a large block doesn't fit the page, it is somehow broken. I've investigated several TeX resources but I still cannot find any convenient solution. I've found related thread at http://tex.stackexchange.com/questions/185059/preventing-page-break-after-th e-first-or-before-the-last-list-item That solution with \pagecheck looks promising, but it has to be implemented on ConTeXt/Lua side. It requires adding 'checking' commands to proper places. Only ConTeXt knows the item tree, it can count number of item in every level and then decide where placing the command is appropriate. The \testpage or \testcolumn are not IMHO sufficient here. They cannot prevent breaking after the first primary. The optional value [2] should somehow be cummulated. Moreover, testing the number of lines is weak as index entries can be long or with many page references requiring more lines than one. \testpage[2] % keep first two together (generalized rule 2) primary-01 \testpage[2] % (rule 1) primary-02 secondary-01 secondary-02 \testpage[2] % (rule 3) secondary-03 secondary-04 primary-03 % how to set rule 3 here? Maybe some kind of 'samepage' would be better here. http://tex.stackexchange.com/questions/64363/context-equivalent-of-latex-sam epage \startsamepage primary-01 primary-02 secondary-01 secondary-02 % placing soft page-break % http://www.tex.ac.uk/cgi-bin/texfaq2html?label=nopagebrk \pagebreak[0] secondary-03 secondary-04 primary-03 \stopsamepage Unfortunately, all this would have to be implemented on engine side during rendering index entries. Or are there any ways already? Thanks, Jan

testcolumn error
by Jan Tosovsky 27 Jun '14

27 Jun '14

Dear All, the following MWE works fine, but when that 'First line' is uncommented, I am getting 'Undefined control sequence' error in the console (ConTeXt - 2014.06.22). \starttext \startcolumns[n=2] %First Line \testcolumn[2]\input{tufte} \stopcolumns \stoptext Any idea what is wrong here? Thanks, Jan

Conditional keep-with-next rules
by Jan Tosovsky 27 Jun '14

27 Jun '14

Dear All, in my index I can see disturbing page breaks. primary-01 primary-02 secondary-01 ------- ( next page ) ----- secondary-02 primary-03 instead of primary-01 ------- ( next page ) ----- primary-02 secondary-01 secondary-02 primary-03 Is it possible to somehow define conditional keep-with-next rules? I'd like to express: (1) keep always the primary with the first secondary (this seems to be implemented) (2) keep always the first secondary with the next secondary (3) keep always the last secondary with the previous secondary And similarly for tertiary. As the Index is generated, I can't see an easy way to accomplish something like this. I hope I am wrong :-) Thanks, Jan

latest beta, problem with natural tables and alignment character
by Brian Landy 27 Jun '14

27 Jun '14

Hi, I was testing the latest beta (2014.06.15) and noticed I am getting incorrect output using natural tables with alignment characters. I produced a small example that demonstrates the problem, and attached output created with the version I'm testing (bad.pdf) and my prior version (good.pdf, ConTeXt 2013.06.10). You can see in the bad file that ConTeXt doesn't properly align on the "-" and it introduces spurious spaces. Best regards, Brian

Preparing a weird index.
by john Culleton 27 Jun '14

27 Jun '14

I have a customer that uses a publisher that has truly weird requirements. The weirdness is that the locaters are not page numbers but paragraph numbers. And some paragraph numbers start with the prefix 'BO' and others with the chapter number. so a correct sequence would be BO.15 3.2 A finished sequence would be goddess @@ BO.15 3.2 3.5 The sort order has to be letter by letter, as defined in the Chicago Manual of Style. Can Context sort and summarize these locaters? I can even change the BO sequence to 0 (zero) and then change it back later on. The key is can Context sort by paragraph number rather than page number for an index. I have looked into Xindy for this job but the learning curve is pretty steep and the documentation pretty opaque. makeindex won't handle decimals for locators. I don't mind doing a little reformatting along the way (I already have for this project) but I don't want to rewrite makeindex or xindy just for this job. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html

Configure AUCTeX to run context not texec
by Michael Ash 27 Jun '14

27 Jun '14

Dear all, I have a working version of context mash-laptop:~$ context --version mtx-context | ConTeXt Process Management 0.60 mtx-context | mtx-context | main context file: /usr/share/texmf/tex/context/base/context.mkiv mtx-context | current version: 2013.11.07 15:28 However, I edit files in emacs/AUCTeX and the compile command "C-c C-c" calls "texexec" instead of "context" and so can't compile in emacs. Does anyone know how to change the command from "texexec" to "context" in emacs/AUCTeX? Thanks.

meeting
by Hans Hagen 27 Jun '14

27 Jun '14

Hi, In case you didn't consider it yet ... in a couple of months we have the context meeting and this is a perfect opportunity to meet those involved in development and support. You can participate in discussions about upcoming developments, express wishes, get sneak previews, get your problems solved (meetings are quite efficient for that). Personally I like those meetings because it gives a face to users and also gives an idea in what direction to move. Also, tex related meetings are kind of special (beware, one can get hooked to them). If you have ideas for topics, let us know asap, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
