[NTG-context] math formula linebreak
Hi,
for nice linebreaking we can adjust math formulas by the use of NC, NR
alignment.
But if someone only wants long formulas to fit in a defined area, and want them
to break automatically ... is there a handy solution?
(Below are examples that don't work)
Thanks,
Steffen

[NTG-context] [***SPAM***] Widows: penalty without efffect (ConTeXt iv)
Dear List, I ran into trouble with the widow/orphan-control in context. I searched the mailinglist, and saw that there were some other threads on the topic bevore, but as far as I am concerned what was suggested there did not work for me when I tried it. I run context iv using the version which comes with TexLive 2011. First trail was to include \widowpenalty=9000 and \clubpenalty=9000 at the start of the document, before \starttext (cause I do my setups, and definitions there) As this did not work I tried to put them after \starttext. As well I lowered \brokenpenalty. But both approaches, which were suggested in previous Posts on the ntg-context list failed to show an effect in my case. Is there anything I could do to prevent the widow lines? PS.: As I may be doing any noobish errors, here an overview of the documents structure and the placement of the penalty-commands _ \widowpenalty=9000 \clubpenalty=9000 \definepapersize[janssize][width=190mm, height=245mm] \setuppapersize[janssize][A4] %we can use something like [A5][A4], which is a a5 Page sized Document printed on a A4 sheet \setuplayout[grid=yes, marking=on, location=middle, backspace=30mm, width=110mm]%former: location=doublesided \starttext \startstandardmakeup \stopstandardmakeup \startfrontmatter %TOC... \stopfrontmatter \startbodymatter %the main stuff goes here % Loads of text \stopbodymatter \startappendices %appendices go here \stopappendices \stoptext ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

You can change the default penalties with \setuplayout[setups=…], the default setting is \setuplayout[setups=*default] but you can change this to “setups=*strict” which should help.

[NTG-context] Can't generate an epub - what am I doing wrong?
Hello all,
my problem is as in the topic;). The minimal example from the wiki
works fine, but this does not:
\setupbackend[export=yes,xhtml=yes]
\settaggedmetadata
[title=My Document,
author=A. U. Thor]
\starttext
\startchapter[title={First chapter}]
\input tufte
\stopchapter
\startchapter[title={Second chapter}]
\input knuth
\stopchapter
\stoptext
The resulting epub file (after the mtxrun, of course) does not contain
any metadata; also, there is no chapter structure whatsoever.
What am I missing?
TIA,

You can use \currentcomponent, \currentproduct and \currentproject to print the

Because I can imagine a 70 percent solution being a big help already. Partly both. The question is not so much the difficulty in choosing break-points (which is easy: before all \mathbin atoms, after \mathpunct if needed, etc). The hard part is how to align the split up portions, and choosing different alignments changes the line widths, and therefore affect future line-breaks. The old manual of breqn (the one by Michel Jones) had some discussion on the different alignment of display math. They are also explained nicely in the book on typesetting math by AMS (I forget the author's name). In principle, one can follow the same approach as Knuth did for line-breaking text (define penalties and then solve a dynamic program to find the layout that gives the lowest score). The breqn package does implement such an algorithm that works well in most cases. I wish that the breqn algorithm were described somethere; then one could play around implementing it in luatex. Trying to read breqn code to understand the algorithm is very difficult.

Hi Aditya, I wish that the breqn algorithm were described somethere; then one could play around implementing it in luatex. Have you seen the new User's Guide yet? It's from last May, very recent, so it may not have been there yet when last you looked. It includes the entire source code, and comments that quite thoroughly: the ratio works out to 16 lines of comment per 26 lines of code. (A page is about 42 lines.) And the comments go into the how, and not just the what. Might be useful at some point in the future, if it is indeed new. http://ctan.unixbrain.com/macros/latex/contrib/mh/breqn.pdf --Sietse P.s.

for nice linebreaking we can adjust math formulas by the use of NC, NR

When I needed something like that, I used \allowbreak with inlinemath.
In your case, you could do:
\bTABLE[frame=on,align=right,width=10cm]
\bTR
\bTD
$I=\big\{\lambda u(x_0-\pi^H K)\allowbreak+(1-\lambda)[\pi^L
u(x_0-K+(1-\pi^L)Z_{L'})\allowbreak+(1-\pi^L)u(x_0-\pi^L

u(x_0-K+(1-\pi^U)Z_{U'})\allowbreak+(1-\pi^U)u(x_0-\pi^U Z_{U'})\big\}.$
\eTD
\eTR
\eTABLE
This will just flow it like regular text. I don't know if this is good
enough for your needs. If not, you can add another way to your list of
ways ;-).

Re: [NTG-context] math formula linebreak
Addendum: I just bumped into Morten Høgholm's bachelor's thesis. Automatic line-breaking of displayed math expressions https://sites.google.com/site/mortenhoegholm/breqn-thesis.pdf That thesis contains a conceptual explanation of the breqn algorithm (or at least the algorithm he used when reimplementing breqn as l3breqn). Might be useful if/when somebody decides to have a go at improving ConTeXts math breaking. The thesis also contains the code of l3breqn, but that is rather more sparsely commented than the code in the breqn.pdf manual. --Sietse ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___
[NTG-context] beta
Hi, There is a new feature in mtxrun: As I wanted to acccess the help on the wiki, I've added a feature to mtxrun that can be used in an editor: mtxrun --gethelp --url=http://www.contextgarden.net/Command/setuplist; Actually, one can also use this: mtxrun --gethelp --url=http://www.contextgarden.net/Command/%command%; --command=setuplist So, in scite I do: mtxrun --gethelp --url=http://www.contextgarden.net/Command/%command%; --command=$(CurrentWord) and hitting F1 takes the current word and runs this command. On windows it effective boils down to start the url I have no clue what happens on unix. Ps 1: Isn't it possible to also support /command on the wiki? It looks like the url resolver is case sensitive. Ps 2: one can also run mtxrun --script server --start --auto and then use mtxrun --gethelp --url=http://localhost:31415/mtx-server-ctx-help.lua?command=%command%; --command=$(CurrentWord) but the garden provides more info.

Aditya Mahajan wrote: Short answer: No easy solution exists. Is this because allowing automatic line breaks in math mode is itself hard to implement, or is the basic mechanism possible but preventing stupid/ugly breakpoints is hard? Because I can imagine a 70 percent solution being a big help already. Partly both. The question is not so much the difficulty in choosing break-points (which is easy: before all \mathbin atoms, after \mathpunct if needed, etc). The hard part is how to align the split up portions, and choosing different alignments changes the line widths, and therefore affect future line-breaks. The old manual of breqn (the one by Michel Jones) had some discussion on the different alignment of display math. They are also explained nicely in the book on typesetting math by AMS (I forget the author's name). In principle, one can follow the same approach as Knuth did for line-breaking text (define penalties and then solve a dynamic program to find the layout that gives the lowest score). The breqn package does implement such an algorithm that works well in most cases. I wish that the breqn algorithm were described somethere; then one could play around implementing it in luatex. Trying to read breqn code to understand the algorithm is very difficult. When I'm done ceaning up the pending tex and lua code, I'll look into these issues. It's probably not that hard to come up with a solution in lua (one of the pet projects on my list).
