bold math
by Mojca Miklavec 03 Jul '09

03 Jul '09

Hello Hans, I wanted to use \definetypeface [boldmath] [mm] [boldmath] [latin-modern] [default] \starttext $\boldsymbol θ$ \stoptext but it seems to fail in mkii and has no influence in mkiv. (The workaround in mkii is to use \theta instead of θ, in mkiv it makes no difference.) 1. Is there any simple patch that could make θ work in mkii? (I'm working with mkii at the moment) 2. I have no idea what to do in mkiv case. Some of symbols (including bold greek) exist is the same font, some don't and might require another ("bolder") font. Maybe fixing the behaviour of \boldsymbol and a few mappings for greek could be enogh to start with. I have tried to enter "MATHEMATICAL BOLD ITALIC SMALL THETA" directly with LM, but it didn't work (probably there are some mappings still missing, but it's a bit uncomfortable to type proper mathematical symbols anyway as editor is somehow lacking the characters and keyboard would have to be reconfigured heavily).

Unwanted empty last page in doublesided document
by B. Tommy Jensen 03 Jul '09

03 Jul '09

I am using Context mkII and have the following challenge: I am using a doblesided layout and want to have an even total number of pages. The last chapter should have an empty trailing page (if necessary) to add up to the right number. The problem is that I always get an ODD number of pages, and there are _two_ empty last pages at the end of the document. I have tried \installpagebreakhandler with no effect. The attached sample shows the problem - two empty pages at end. I would have expected the document to stop at page 10, but there is an empty page 11 as well. Does anyone have a clue here? Regards, Tommy Jensen Sample text follows: \setuppagenumbering[alternative=doublesided] \starttext \startbodymatter \chapter[]{Kap 1} \chapter[]{Kap 2} \chapter[]{Kap 3} \chapter[]{Kap 4} \chapter[]{Kap 5} \stopbodymatter %----------------------------------------------------------------------------- % Necessary to suppress emtpy last page in doublesided pagenumbering mode (no effect!) \installpagebreakhandler{last}{} \stoptext

letter/correspondence module
by Henning Hraban Ramm 03 Jul '09

03 Jul '09

Hallo Wolfgang! ;-) Since my old letter and CV environment doesn't work anymore in MkIV, I'm trying to reproduce it with t-letter. At the moment I struggle with the reference keys: \setupletterstyle[reference][ alternative=d, list={name,street,city,,phone,skype,email,,date}, ] \setupletter[name,street,phone,date,skype,email][ separator={: }, titlestyle={\ss\tfxx}, ] The keys street, city and skype aren't defined in your module. I found where the other keys are defined (and I guess I could mine in or use a similar approach in my environment), but I'm clueless, where the translation comes from - I grepped eg. after "Telefon" without results, and I think I looked into every file of your module. I guess it would be interesting how to define your own keys, maybe some IM adresses etc., also for other users. Would it be possible to use unknown keys just unchanged? I.e. if I say \setupletter[ Skype={fiee.visuelle} ] to get just "Skype: fiee.visuelle"? More questions will follow... I'll try to get my logo at the right place by myself before... Greetlings from Lake Constance! Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

Re: [NTG-context] How to Determine the Current File Name and Line Number AND PAGE NUMBER in the ConTeXt Source?
by ivo welch 03 Jul '09

03 Jul '09

is there also a way to determine the current output page number on which typesetting is currently being made? (I know this is a difficult problem in LaTeX, and I presume the same is the case for ConTeXt, because it uses the same underlying TeX engine.) /iaw

Problem with \atopwithdelims & Co.
by Lutz Haseloff 03 Jul '09

03 Jul '09

Hi Hans, Hi Taco, Hi all, a couple of days ago I complained about not adapted delimiters around constructions with \atopwithdelims. With LuaTeX, Version beta-0.41.0-2009070222 (Web2C 2009), this problem persists. After reading the last luatexref-t.pdf I tried following: \starttext \Ustartmath\Ustack {a \atopwithdelims() b}\Ustopmath \startformula \Ustack {a \overwithdelims[] b} \stopformula \stoptext Greetings Lutz

Page Break Events
by Andreas Schneider 01 Jul '09

01 Jul '09

Hello, since that question has probably gone by unnoticed in my other posting, I'll ask more directly here: How can I react on page breaks (in MkII)? More specifcally: I need to reset a variable whenever a pagebreak occurs (atleast when automatic page breaks occur ... but it would be nice, if it also works for manually broken pages). The only thing that I was able to find was \insertpagebreakhandler ... but it seems as if this can only be triggered manually with \page. Thanks in advance! Andreas.

How to Determine the Current File Name and Line Number in the ConTeXt Source?
by Tad Ashlock 01 Jul '09

01 Jul '09

Is there a convenient way within a Lua block to determine the current file name and line number of the source file being processed by ConTeXt? For example: (test.tex) --------------------------------- \def\ShowLineNumber{% \ctxlua{print('current line number:', tex.current_line_number()) print('current file:', tex.current_file_name())}} \starttext a line \ShowLineNumber another line \ShowLineNumber \stoptext --------------------------------- With the following displayed: --------------------------------- current line number: 6 current file: test.tex current line number: 9 current file: test.tex --------------------------------- I've considered hooking into the open_read_file callback and tracking the file name and line number (via reader) myself. But that seems a bit heavy handed if the file name and line number information are available more directly. And since that information is needed for error reporting, I'm thinking there's a good chance it is accessible. (Just in case you're interested, the purpose of this is to be able to assemble code segments during the ConTeXt processing into external files with #line directives ala the C preprocessor. That way if the subsequent compilation of the external file results in an error, the error message can refer back to the line of code in the ConTeXt source file. This is part of the literate programming module that Kevin Robbins has been describing in another thread.) Thanks, Tad
