Thesis example, source files
by Shishir Kumar 16 Oct '10

16 Oct '10

Hi, I am a PhD student and am starting on writing my thesis. I have looked at Aditya's and The Thanh's thesis, and they are very nice. Unfortunately, I could not find the sources for these. Does anybody know if they are available somewhere? It would be nice to have them on the wiki. The problems that I faced were related to placement of table of contents, references, figures and fonts. I also found that quite a lot of information is available on the wiki and at Pragma, but it is not organised well and needs rather large amount of time investment (both of which may be due to my ignorance).

Is it possible to pass unmarked paragraphs into Lua for processing
by Kevin D. Robbins 15 Oct '10

15 Oct '10

Hi all, I am wondering if and how it might be possible to catch all unmarked paragraphs in a TeX file and pass them into Lua. So, in the following example, each of the first three unmarked paragraphs would be passed to the Lua function "process_paragraph" for optional processing, but the fourth paragraph between \startmarkedparagraph...\stopmarkedparagraph would not be passed to "process_paragraph". I want the Lua function to be able to eat each of the first three unmarked paragraphs and optionally write some processed version back out to be typeset, but there should be the possibility that none of the paragraphs are typeset at all. In the latter case that no text is to be typeset at all, is there a way to prevent ConTeXt/LuaTeX from creating an empty PDF? \startluacode def process_paragragh (par) -- Some magic here... -- Maybe a context (processed_par) to typeset the processed paragraph... end \stopluacode \starttext Thus, I came to the conclusion that the designer of a new system must not only be the implementer and first large||scale user; the designer should also write the first user manual. \startitemize \item One \item Two \item Three \stopitemize The separation of any of these four components would have hurt \TeX\ significantly. If I had not participated fully in all these activities, literally hundreds of improvements would never have been made, because I would never have thought of them or perceived why they were important. But a system cannot be successful if it is too strongly influenced by a single person. Once the initial design is complete and fairly robust, the real test begins as people with many different viewpoints undertake their own experiments. \startmarkedparagraph Thus, I came to the conclusion that the designer of a new system must not only be the implementer and first large||scale user; the designer should also write the first user manual. \stopmarkedparagraph \stoptext Thanks, Kevin

Problem with \date command
by Cedric Mauclair 15 Oct '10

15 Oct '10

Hi all, Today I wanted to use the command "\date[d=15,m=10,y=2010][weekday]". It gives "Friday" as it should. However "\date[d=2,m=1,y=2011][weekday]" gives the same result which is wrong (it's a Sunday). In fact, whatever the supplied date, it gives "Friday". I guess the parameter isn't taken into account here. Bug or feature? -- Cédric

en-dash for ranges of numbers in Bibliographies
by Florian Wobbe 15 Oct '10

15 Oct '10

Hi, in BibTeX databases ranges of numbers are usually listed with a single dash (e.g. 3-7) for compatibility reasons. Therefore the standard BibTeX styles convert a single dash in page numbers or range of numbers to a double dash (3--7). How do I get the same behaviour for \volume \issue \pages in the bibliographic module? Thanks! Cheers, Florian

\typefile from n-th line
by Procházka Lukáš Ing. - Pontex s. r. o. 15 Oct '10

15 Oct '10

Hello, I'd need to \typefile a file from n-th line (= ignoring first n-1 lines). Is there such an option for \typefile macro? (http://wiki.contextgarden.net/Reference/en/typefile is silent.) I tried: \typefile[default][lines={10}]{a_file.txt} % Start at line 10 \typefile[default][lines={10,+1}]{a_file.txt} % Start at line 10, step = 1 \typefile[default][start=10]{a_file.txt} % Start at line 10 \typefile[default][from=10]{a_file.txt} % Start at line 10 No success. (The last Ctx minimals, WinXP.) Lukas

Access figure data?
by Brian Wedde 15 Oct '10

15 Oct '10

Is there any way to get access to the data about external figures? I would like to know the pixel height/width of the actual image. [I am trying to typeset a mass of html-based documents with images using a series of scripts. The images need to be positioned somewhat like they would be on the screen. However, the html itself carries no info about the image.]

How to call a ctx command with parameters from Lua
by Procházka Lukáš Ing. - Pontex s. r. o. 15 Oct '10

15 Oct '10

Hello, this thing was probably shown during last Ctx meeting, but I can't remember the answer. Let's ave the Ctx code: \typefile[default]{Myfile.txt} and I'd need to call this command by Lua, like: \startluacode context.typefile("MyFile.txt") \stoluacode But how to pass the "[default]" option? I remember that key-value pairs are passed by tables (context.cmd{key="val"}), but how in this case? Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

Titles that spill out
by Brian Wedde 14 Oct '10

14 Oct '10

Here is a simple section header. It runs way out of the margin. Any idea why? I do not want hyphenation. Words that run over the boundary should be skipped to the next line down. Why does it not do that here? Also note that if i change "flushleft" to "middle", it works fine (except that i don't want it middle-aligned!) \setuphead[section][align={flushleft,nothyphenated}] \starttext \showgrid \section{XXX XXXX XX XXXXXXXX XXX XXXXXX XXX XXXXXXXXXXXX XXXX XXXXXXX XXX} \stoptext %%%%% Here's another similar example: \setuplayout[ width=6.5in ] \setupbodyfont[ 10pt,rm ] \definebodyfont [10pt] [rm] [ hh=Regular sa 1.85 ] \setupheads[ align={flushleft,nothyphenated}, tolerance=strict ] \setuphead[section][ number=no, textstyle=\hh ] \starttext \showgrid \section{XXX XXXX XX XXXXXXXX XXXXXX XXXXXXXXXXXXXXXXXXX XX XXXX XXXXXXX XXX} \stoptext Thanks for your help.
