documentation
by Yuri Teixeira 08 Jul '14

08 Jul '14

Hello, I'm sorry this probably is a dumb question but I'm really lost in my searches. I'm new to context/tex and have been learning/finding information in the wiki at the contextgarden.net for the past couple of weeks. Some of information there don't seem up to date but nothing unusual in an unofficial wiki. For some reason (isp/dns/something) the contextgarden.net has been unavailiable to me since yesterday even though some verification sites show it up and some show it down (http://www.isitdownrightnow.com been one of the later). That got me wondering if there are easy official docs. I've seen the pdfs at pragma-ade.com but the most general ones I tried are from 1999 (ms-cb-en.pdf) and 2001 (cont-eni.pdf). Are these up to date with the current developments? I belive they are compatible but having seen examples of changes in the wiki I a little unsure. Furthermore, the parameter behavior description in the command reference seem a bit... dry. So here's my plea for a little bit more love for the documentation. In any way, thank you very much for an awesome language, I'm glad I researched thoroughly before jumping into latex. YT

Bug in \setupinterlinespace ?
by Otared Kavian 08 Jul '14

08 Jul '14

Does anybody know how to change the interline space in a part of a document? I send again the message below: Hi all, I don’t know how to change the interline space in a chapter. In principle I thought that if at some point I have used for some reason \setupinterlinespace[4.0ex] then saying \setupinterlinespace[reset,small] would reset the interline space to its default value, but this is not the case. The version I am using is: ConTeXt ver: 2014.07.04 15:55 MKIV beta fmt: 2014.7.5 int: english/english Here is a minimal example: %%%% begin bug-interline.tex \setupinterlinespace[4.0ex] \starttext \input knuth.tex \page \setupinterlinespace[reset,small] \input knuth.tex \stoptext %%%% end bug-interline.tex Thanks for your help: OK

underbraces get progressively more misaligned (w/ minimal example)
by Sanjoy Mahajan 07 Jul '14

07 Jul '14

Dear list, As I copyedited my book, I noticed examples where the underbraces in math formulas were not aligned vertically, especially toward the end of the book. Eventually I realized it was not due to my growing copyediting skill, and I have made the following minimal example showing the problem (I am using 2014.05.17 MkIV): \setupformulas[indentnext=auto, spacebefore=none, spaceafter=none] \starttext \dorecurse{3000}{ \placeformula\startformula \underbrace{\hbox{yyyy}}_{\rho} = \underbrace{\hbox{yyyy yyyy yyyy}}_{\rho} \stopformula } \stoptext It'll produce a 162-page file. On the formulas on page 1, the two underbraces in each equation are aligned. But there seems to be some kind of slow leak, because the underbraces become ever more misaligned. By page 162, they are visibly misaligned by maybe 3pt. If I increase the recursion count to 30000, on page 2129 the misalignment is about 30pt. Taking out the \placeformula makes the misalignment go away. I tried to reproduce the problem with plain LuaTeX, using the tex file below, but the underbraces came out aligned. \newcount\foo \foo=3000 \loop $$ \underbrace{\hbox{yyyy}}_{\rho} = \underbrace{\hbox{yyyy yyyy yyyy}}_{\rho} $$ \advance \foo -1 \ifnum \foo>0 \repeat \end Any thoughts on this very strange issue? -Sanjoy

This should be possible without hacks but without a example I can’t provide more than a simple example code. \newconditional\IndexState \define[1]\IndexInternalCommand {\doifelse{#1}{MyPrimary}{\global\settrue\IndexState}{\global\setfalse\IndexState}#1} \define[1]\IndexCommand {\setfalse\IndexState \setbox\scratchbox\hbox{#1}% \ifconditional\IndexState \column \fi \box\nextbox} \setupregister [index] [ textcommand=\IndexCommand, deeptextcommand=\IndexInternalCommand] Wolfgang

[garden] luatex git mirror out of sync
by Philipp Gesang 05 Jul '14

05 Jul '14

Hi all, there’s been a lot of changes lately to the Luatex SVN but the mirror on the Garden doesn’t appear to match pace. Here’s the experimental branch on the Garden and on supelec: http://git.contextgarden.net/context/luatex/commits/origin/experimental https://foundry.supelec.fr/scm/viewvc.php/branches/experimental/?root=luate… Commits after 25 Apr are missing on the former. For example, the git svn clone on my machine has much more recent commits: * 6a9a4d7 - (HEAD, experimental, experimental) fixed a bug with braces (12 hours ago) <luigi> * a0780a1 - fixed wrong procedure keyword (29 hours ago) <luigi> * 0e4f41f - fixed the Lua stack (4 days ago) <luigi> * 4f4cb51 - sync with metapost TL 2014 (8 days ago) <luigi> * c0033b5 - add pdf_stream_filter_callback to lcallbacklib.c (8 days ago) <luigi> * 958dc74 - sync with trunk (2 weeks ago) <luigi> ... Perhaps a cron job is broken somewhere? Also I noticed that if I click the “compare” button on this form: http://git.contextgarden.net/context/luatex/compare?from=master&to=experime… I get a 500 (“We’re sorry, …”). Can anybody reproduce this? Best regards, Philipp

Testing the param value
by Jan Tosovsky 05 Jul '14

05 Jul '14

Dear All, I am hacking the context index entry rendering... ;-) ... but I am stuck with a simple comparison How can I test the given entry if it equals to the specified one? The following code has no effect. \unexpanded\def\defaultregisterentry#1#2#3#4% % #1:processor #2:internal #3:seeindex #4:word {\def\currentregisterpageindex{#2}% % start hacking \def\myword{#4}% \ifx\myword{My Primary} \column % do something \fi % stop hacking \strc_register_injector_process ... What is the proper syntax? Thanks, Jan

ToC depth (and headers) per section block
by Rik Kabel 05 Jul '14

05 Jul '14

How can I specify different section depths for different parts in a document in the TOC? That is, if the document structure is: Front Matter Body Matter Part 1 Chapter 1 Section 1 Chapter 2 Section 1 Section 2 Part 2 Chapter 1 Section 1 Section 2 Chapter 2 Section 1 Appendices Chapter 1 Section 1 Chapter 2 Section 1 Back Matter Notes Bibliography How can I generate chapter and section entriess in the TOC for Part 1, but chapter entries only (no section entries) for Part 2 and the Appendices. I currently do this by defining a new header equivalent to section and using that for Part 2 and Appendix sections. Since it is not included in the lists used by the contents combinedlist, it does not get set. Is this the best way to do this? If instead I want one depth for all body matter parts and a different depth for the appendices, is there a solution that could be keyed on system modes or on section blocks, thus moving all of the styling to the preamble (to use a LaTeX term)? I currently do that to support different header formats in the body matter and appendices, using the following method, but I suspect that there may be a more effective way to do that as well. \startsetups [Header] \startallmodes [print,*bodypart] {\color[PrintHeaderColor]{\PrintHeaderFont {\llap{\getmarking[chapternumber]~}\getmarking[chapter]}} \stopallmodes \startallmodes [print,*appendix] \color[PrintHeaderColor]{\PrintHeaderFont {\getmarking[chapter]}} \stopallmodes \stopsetups \setupheadertexts [] \setupheadertexts [\setups{Header}][][][\setups{Header}] Again, I prefer a method that can be implemented in the preamble.

No new paragraph after framedtext
by Flavien Lambert 05 Jul '14

05 Jul '14

Dear all, I was wondering if there was a way to avoid a new paragraph after a framed text. For example, the following code \starttext \framedtext[width=6em]{abc}\framedtext[width=6em]{abc} \stoptext produces two boxes on top of each other. Is it possible to make them side by side? I could use a table but I would like to keep the possibility of playing with the framebox size as much as I want (like a patchwork of boxes of different sizes that would span part of the pages). Best, Flavien.
