Transparency without colors.
by Andre Caldas 18 Dec '12

18 Dec '12

Hello! In my "simplesteps" module, I'd like to adjust the transparency of the foreground color. The file tex/context/base/colo-ini.mkiv suggests that there is a way to do that: % Currently in mkiv transparency is implemented independent of color. This costs % a bit more processing time but gives the possibility to apply transparency % independently in the future. Is this useful? If not we may as well combine them % again in the future. By coupling we are downward compatible. When we decouple we [...] How can I define the transparency of some text? André Caldas.

Module for Commutative Diagrams.
by Andre Caldas 18 Dec '12

18 Dec '12

Hello! Some days ago, I have written a module for writing "commutative diagrams" using MetaPost. Definition of "commutative diagrams": https://duckduckgo.com/?q=commutative+diagrams The module lives here, now: https://bitbucket.org/andrecaldas/context-commutativediagrams The module still needs a lot of working... but for very, very simple diagrams, it works! At least for me... =o) Comments are very welcome, André Caldas. PS: I have to submit the final version of my doctoral thesis just before the end of the world (20/12/2012). For that reason I have not worked on the simplesteps module... but I'd like to thank all the support given in my last thread.

DocBook
by Roger Mason 18 Dec '12

18 Dec '12

Hello all, I have a manuscript to review that I have managed to coerce into DocBook xml. I'd like to turn it into context so that I can mark it up in a comfortable environment. I just tried Simon Pepping's DocBookInContext package from 2003, but it fails on the provided test document: ! Undefined control sequence. l.968 \stelsectiein pandoc is not an option for me at the moment: I am currently using Arch Linux and have not been able to get their Haskell installation to finish successfully. Thanks for any ideas. Roger This electronic communication is governed by the terms and conditions at http://www.mun.ca/cc/policies/electronic_communications_disclaimer_2012.php

framed algorithm / float: problems with line break
by Andreas Mang 18 Dec '12

18 Dec '12

Dear all, Quick access: there is no line break in case algorithmic is used together with framed as a float. I'd like to put some pseudocode in my document. I've used the algorithmic module. Since I'd like to refer to the algorithm in the text, I've defined a float environment. However, putting the pseudocode into my document, I've realised that it does not really stand out from the text. My first idea was to put some box around it. In the garden I've found some example for using framed together with floats: http://wiki.contextgarden.net/Framed However, this screws up the line break in the algorithmic environment. I could define manually the size of the box, but I think there might be better solutions. Any ideas or better ways for achieving this or a similar behaviour?! Thanks in advance.

Centered multiline chapter title
by hanak＠wpb.cz 18 Dec '12

18 Dec '12

Hello, I need to format my chapters in the following way: - The chapters are centered (midaligned). - Some chapters are long, so they have to be multilined. - The chapter title should be in capital letters, but in the header should it be without capitalisation. - When the chapter title is multilined, only the first line should appear in the header, followed by "...", the same in TOC - When the chapter title is multilined, I want to choose the point of line break with "\\" So something like this: \chapter{FIRST CHAPTER TITLE} (in the header and TOC will be "First chapter title") \chapter{SECOND CHAPTER TITLE \\ WHICH IS VERY VERY VERY LONG} (in the header and TOC will be "Second chapter title...") I tried the following setup for the chapter: \setuphead [chapter] [after={\blank[2*line,fixed]}, header=empty, textcommand=\midaligned, style={\chapterfont\WORD}, sectionset=none, indentnext=no ] But when I try to process the file, I will get the following error: structure > sectioning > chapter @ level 2 : 0.1 -> Second chapter title \\ which is very very very looong ! Missing } inserted. system > tex > error on line 1 in file test.tex: Missing ... 1 >> \environment test_environment 2 3 \startcomponent test19 4 5 \product test 6 7 8 \chapter{Second chapter title \\ which is very very very looong} 9 <inserted text> } <to be read again> \endgroup \\->\endgroup \par \doalignline {\hss }{\hss }\begingroup l.1 Second chapter title \\ which is very very very looong \ctxcommand ...\directlua \zerocount {commands.#1} \getheadtitle ...lecommand \relax \structuretitle \else \normalexpanded {\no... ... l.10 ...r title \\ which is very very very looong} If I don't try to enforce line break in the title with "\\", the file is processed without problem, but also without making anyline break at all -- the whole long chapter title is one very long line. If I don't use "textcommand=\midaligned", I am able to make multiline chapter with my own line break, but the title is left-aligned... Could anybody tell me, how to make properly the chapter setup according to above described rules? Thank you in advance. Pavel

Whitespace and quotechar in database module
by Marco Patzer 18 Dec '12

18 Dec '12

Hi, the following two database examples produce different output due to the white space between the field separator and the quotechar. \usemodule [database] \defineseparatedlist [CSV] [quotechar=", before={\starttabulate[|l|l|]}, after=\stoptabulate, first=\NC,last=\NR, left=,right=\NC] \starttext \startCSV alpha, loremloremlorem beta,"ipsum, ipsum, ipsum" \stopCSV \startCSV alpha, loremloremlorem beta, "ipsum, ipsum, ipsum" \stopCSV \stoptext Can the parser be made tolerant to this space?

Count the words per line
by "H. Özoguz" 17 Dec '12

17 Dec '12

I am setting with grid-set, and I am wondering, if there is a possibility to count the number of words in the lines (not for each single line, but in average over all lines). That would be helpful to get a perfectly readably book (words per row is one of these readability-measures). That tool could ignore hyphenated words at the end of a line, or count it with 0.5, or whatever. Thanks Huseyin

Suggestion for formula numbering
by Zenlima 17 Dec '12

17 Dec '12

Hi, as of actual need I summed up all kinds of formula numbering - some basics are working. You can find this list on my user talk page: http://wiki.contextgarden.net/User_talk:Zenlima As I also found a note in str-math.mkiv that it needs to be rewritten and the example syntax which leaded me to confusion in the past, I worked out a suggestion for a more intuitive syntax for formula numbering. In sum it ends with: All three commands: \NR \placeformula \formualanumber will share the same attributes: * sublevel (maybe better: formulalevel or just level?) to define and concrete the (sub-)level of the formula * listlabel (maybe textlabel? the numberlabel is still needed) to add a entry in the list of formulas * reference just a classic reference in order to link to it so that the syntax is more intuitive during the writing. Also. this way the commands: placesubformula placenamedformula placenamedsubformula startstopsubformulas subformulanumber will become needless. For the "why" and examples please look at: http://wiki.contextgarden.net/User_talk:Zenlima#Suggestion_for_new_syntax I hope you will find parts you like and feel free to add your opinion. :-) H.

Desperate help needed: Formular numbering and List of Formulas
by Zenlima 17 Dec '12

17 Dec '12

Hi, I am closing my dissertation (finally) but I had to realize that subnumbering of formulas is still not working in mkiv. Unluckily going back to mkii is not an option for other reasons. For that I really need help to bring back a fully working formula numbering. I searched the entire wiki and mailing list for possible examples and put all in one test file - I got non to work but maybe I also made a mistake somewhere. Additionally I wrote everything on my talk page of the wiki: http://wiki.contextgarden.net/User_talk:Zenlima If every method has to be fixed my priority is the \NR[+][c]-method. Maybe someone can give additionally hints how to get a proper list of formulas. I attached the test file with its pdf result in addition to the wiki page. Thanks H.
