It's so kind of you. Your example really helps me 'cause I can learn javascript and ConTeXt by books but there are few materials about how to associate them. Still, I'm sorry I have to open a new thread.

TeX trigger in MP macro
by Peter Rolf 06 Sep '06

06 Sep '06

Hi all, Currently I am using \startuniqueMPgraphic{foo} ... if (\DbgFill=0) : fill whatever fi ... \stopuniqueMPgraphic in my MP graphics. \DbgFill (0|1) is just a trigger, which prevents filling in case of visual debugging. Instead of always writing this 'long' form, it should be possible to use a self written mp-macro instead. But my naive approach def dbg_fill (expr p) = if (\DbgFill=0) : fill p ; fi enddef ; doesn't work. I get >> DbgFill ! Unknown relation will be considered false. How do I realize this trigger inside pure MP code and set it outside in TeX? The trigger should be global and can change during runtime. Any help is welcome. Greetings, Peter

Footnote Setup
by Pepe Barbe 06 Sep '06

06 Sep '06

Hi, I would like to setup the footnotes so that the footnote in the textbody shows slanted (or just different) to the rest of the text and in sans serif, to avoid some confusion with exponents. So far what I have tried, does not seem to work. In setupfoonotes, style and numbercommand seem to only affect the style for the footnote at the bottom of the page, but not the footnote inside the textbody. Any ideas on how to achieve this? Thanks, Pepe

Thank you very much Peter. I've inserted these code and when I open my pdf file in Acrobat Reader, it crashed :(. But this is not a big deal, I modified it and it's working, but it only tells me that: do_digit(7) at page 0 and the field never changes. I guess I have to specify some link between the JavaScript variant and the ConTeXt. Can you give me just one simplest example that shows JavaScript code var tempstring = "Yes"; in pdf file? Or you could think I'm very boring so can you just suggest some materials that I can find these techniques?

preliminary support for tex4ht is there (for ConTeXt to HTML conversion)
by Mojca Miklavec 06 Sep '06

06 Sep '06

Just to let you know: if you want to convert your ConTeXt documents into HTML, you can try to install tex4ht and replace the old files with new ones: http://www.cse.ohio-state.edu/~gurari/TeX4ht/bugfixes.html (newt4ht.zip) It works OK with the old perl texexec.pl, the ruby version causes some problems, but none of them are fatal. You need DVI as an intermediate format, so if you use texexec.rb, you have to add \setupoutput[dvi] at the top of the document, otherwise tex4ht won't be able to create HTML out of it. You can compile a document with "htcontext filename" or by manually running texexec --use=tex4ht filename tex4ht filename t4ht filename I cannot give you extensible information about how fonts are set up. In MikTeX it worked out-of-the-box, however I didn't play yet to make it work under the stand-alone distribution, but the following link might be of some importance: http://www.cse.ohio-state.edu/~gurari/TeX4ht/mn32.html Support is not that extensive yet, but sections, external images (as long as they reside in the same directory and if they are in PNG/JPG), natural tables, itemisations, "place[something]", buffers, footnotes, very basic frames, math, ... are somehow working. (The big difference with math is that in LaTeX it is changed into bitmap and in ConTeXt it's currently text-based, so you'll get weird results when using \sum or similar, but I think that that is configurable, so if you manage to play enough with it you might be able to get formulas translated into MATHML, which will be displayed nicely in firefox for example.) And I guess that conversion into an OpenOffice document is very similar. I only asked the author to rewrite the pieces of code that caused problems before and to add some additional basic support to context.4ht, so if you have other requests, you should contact the author of tex4ht, not me !!! He adds support based on user requests (his first response was: nobody asked for improving ConTeXt support so far), so if you want to have better support implemented, feel free to ask him. Adding full support for ConTeXt is a bit too optimistic, but stepwise improvements are possible. Comments wellcome. (I currently have some problems with my computer, so I might not be very responsive to additional questions, but I'll try to fix the computer ASAP. Once that I manage to make it work inside stand-alone distr., I'll report how I did it if nobody else does that before me.) Mojca

index page range bug
by Jason Grout 05 Sep '06

05 Sep '06

Hans (or whoever could change this), When using startregister/stopregister commands, if the range is only one one page, then while both a [f] and a [t] are written to the tui file, only one \registerfrom command is put in the tuo file. If there is only one range, it seems like the software deals with it nicely. However, if there are two ranges (like in the example below), then the index incorrectly assumes that the first \registerfrom command in the tuo file corresponds to the \registerto command. Here's an example test.tex: \setuppapersize [letter][letter] \starttext \input knuth KNUTH START\startregister[index][knuthrange1]{Knuth} \input knuth KNUTH END\stopregister[index][knuthrange1] \dorecurse{10}{\input zapf } KNUTH START\startregister[index][knuthrange2]{Knuth} \dorecurse{10}{\input knuth } KNUTH END\stopregister[index][knuthrange2] \completeindex \stoptext test.tui: r f {index} {1} {} {Knuth} {2--0-0-0-0-0-0-0--1} {1} r t {index} {2} {} {Knuth} {2--0-0-0-0-0-0-0--1} {1} r f {index} {3} {} {Knuth} {2--0-0-0-0-0-0-0--3} {3} r t {index} {4} {} {Knuth} {2--0-0-0-0-0-0-0--5} {5} test.tuo: \registerentrya{index}{Knuth} \registerfrom{index}{,}{1}{2--0-0-0-0-0-0-0--1}{1} \registerfrom{index}{,}{3}{2--0-0-0-0-0-0-0--3}{3} \registerto{index}{,}{4}{2--0-0-0-0-0-0-0--5}{5} and the index reads "Knuth 1--5", but it should read "Knuth 1, 3--5" My guess is the problem lies in the line in texutil.rb: if copied || ! ((lastpage == entry.page) && \ (lastrealpage == entry.realpage)) then (sorry, that was one line before my mail program wrapped it). Since the ending [t] reference for the first \stopregister command is on the same page as the first one, the whole section outputting a \registerto command to the tuo file is skipped. Instead, how about making the code check to see if we have a range that ends on the same page as it started? If it does, then just insert a \registerpage command instead of a \registerfrom command. I've corrected this in the perl version (I had an old version of ConTEXt before today, otherwise I would have worked on the ruby version). I also added support for nesting ranges, which I then discovered weren't supported anyway. (I also had to change the sort order on @RegisterEntries so that [f] and [t] entries would be consecutive, instead of all the [f] entries preceding the [t] entries, but it looks like that was fixed already). Here's my code from the perl texutil (with a bunch of comments from me): { # print "$LastPage / $Page // $LastRealPage / $RealPage\n" ; $NextEntry = "{$Class}{$PreviousA}{$PreviousB}{$PreviousC}{$PageHow,$TextHow}" ; $SavedLine = "{$Class}{$PageHow,$TextHow}{$Location}{$Page}{$RealPage}\n" ; # If we are starting a new level, start our nesting over. # This will completely ignore the last non-properly # nested result in the previous heading. if($Copied) { $NestingLevel=0; $TopLevelFromPage=""; $TopLevelFromRealPage=""; $TopLevelFromLine=""; } if ($RegisterState eq $RegStat{"f"}) # If we are starting a range { FlushSavedLine ; if($NestingLevel eq 0) { $TopLevelFromLine=$SavedLine; $TopLevelFromPage=$Page; $TopLevelFromRealPage=$RealPage; } $NestingLevel++; } elsif ($RegisterState eq $RegStat{"t"}) # If we are ending a range { FlushSavedLine ; $NestingLevel--; if($NestingLevel <= 0) { if((($Page eq $TopLevelFromPage) and ($RealPage eq $TopLevelFromRealPage)) or $NestingLevel < 0) { print TUO "\\registerpage$SavedLine" ; } else { print TUO "\\registerfrom$TopLevelFromLine" ; print TUO "\\registerto$SavedLine" ; } $NestingLevel = 0 ; $TopLevelFromPage=""; $TopLevelFromRealPage=""; $TopLevelFromLine=""; } } else # If we have a normal single entry { if ($CollapseEntries) { if ($SavedEntry ne $NextEntry) { $SavedFrom = $SavedLine } else { $SavedTo = $SavedLine } $SavedEntry = $NextEntry } else { print TUO "\\registerpage$SavedLine" } } Of course, if I've missed something, please let me know. I've only started using ConTEXt in the last few weeks. I needed grid typesetting for a book I was working on and I was getting tired of LaTeX not helping me there. I've absolutely loved working with ConTEXt! (well, other than sometimes a frustrating lack of documentation, but there have been lots of good posts on the mailing list that have helped me). Thanks, Jason

Typesetting Math
by Pepe Barbe 05 Sep '06

05 Sep '06

Hello, I am curious about what does everyone around here uses for typesetting Math? Currently I know more LaTeX than anything else for that, but from what I gather to use ConTeXt in full extent I should typeset things directly in TeX or use MathML. So far I've been some LaTeX-like stuff and it was worked fine, but know I want to do more complet layouts that would involve LaTeX style arrays to align equations in several lines. So, what would you guys would recommend? Thanks, Pepe
