Re: [NTG-context] How to test the emptyness of a variable?
by Géry Ogam 10 Nov '13

Thank you very much Aditya, now it works. As you said, the trick was to use \doiftextelse{}{}{} function as test of emptyness function, and \labeltext{chapter} instead of \currentstructurelabel as variable for the test because the latter was never found empty, even when it was. Thus the right code for me is: \define[1] \MyConversion{\doifelse{\currentsectioncountervalue}{1}{\doiftextelse{\labeltext{chapter}}{ONE}{#1}}{#1}} \defineconversion[MyConversion][\MyConversion] \setuphead[chapter][conversion=MyConversion] \starttext \setuplabeltext[chapter=] \chapter{Cool} \chapter{Cat} \chapter{Mouse} \setuplabeltext[chapter=CHAPTER~] \setupheadnumber[chapter][0] \chapter{Cool} \chapter{Cat} \chapter{Mouse} \stoptext

two suggestions to \typesetbuffer
by Pablo Rodriguez 10 Nov '13

10 Nov '13

Dear Hans, I have presentations that include buffers typeset with \typesetbuffer. One of the presentation includes 33 buffers, which are small ConTeXt samples. Any time I change anything on the presentation (not on the buffers themselves), every buffer is typeset again. And the compilation time is longer than probably desired. My first suggestion would be to skip compiling buffers again, if the following three requirements are met: 1. Buffer content (.tmp file, I guess) is identical (checked with a hash) with the previous one from last compilation. 2. PDF file hasn’t been changed since previous complete compilation (md5 sum again). 3. Buffer content was correctly compiled in previous compilation. My second suggestion may be a bit complex to implement, but I think it would be useful. Wouldn’t it be possible that the fonts are only embedded one in the presentation? Many thanks for your help, Pablo -- http://www.ousia.tk

[font-syn.lua] remove call to fontloader.to_table()
by Philipp Gesang 09 Nov '13

09 Nov '13

Hi all, calling fontloader.to_table() appears to be redundant when extracting font names, see the attached patch. On my system I measured 42 (patched) vs 59 (vanilla) seconds for rebuilding the entire index: mtxrun --script fonts --reload --force The resulting index is -- except for the uuid, naturally -- identical in both cases. Best, Philipp

How to test the emptyness of a variable?
by Géry Ogam 09 Nov '13

09 Nov '13

> I'm sure there is also a "cleaner" TeX way, but I'm not experienced enough for that. I think you misunderstood my issue: your Lua way does the same thing than my TeX way: it displays: ONE Cool 2 Cat 3 Mouse but that is NOT what I want. What I want is: 1 Cool 2 Cat 3 Mouse So I need to check if the chapter label has been set empty or not by the user, because it is not empty (let's say the user chose the string "CHAPTER~" for the chapter label) I want to display this: CHAPTER ONE Cool CHAPTER 2 Cat CHAPTER 3 Mouse The way to do that is to check if the variable \currentstructurelabel is empty, so the code must be: \define[1] \MyCommand{\doifelse{\currentsectioncountervalue}{1}{\doifnotemptyelse{\currentstructurelabel}{ONE}{#1}}{#1}} \setuphead[chapter][deepnumbercommand=\MyCommand] \starttext \setuplabeltext[chapter=CHAPTER~] \chapter{Cool} \chapter{Cat} \chapter{Mouse} \stoptext \starttext \setuplabeltext[chapter=] \chapter{Cool} \chapter{Cat} \chapter{Mouse} \stoptext But the problem is that in the second case, even if the chapter label is set empty the command \doifnotemptyelse{\currentstructurelabel} thinks the variable \currentstructurelabel is not empty. So there must be something invisible in it, like a strut or something.

Installing Context on Windows XP
by Nelson Goncalves 09 Nov '13

09 Nov '13

Hello, I want to install Context on Windows XP, but the rsync commands fails because the network ports are closed. And the admin of my company does not want to modify the settings. Is there any other way to install Context on Windows other than the script for the command line ? Thanks, Nelson P.S - I already sacrified a member of my family and did the tours around the pentagram but the admin would not change his mind.....

All ranges of secondaries were treated as primaries so they were collected at primaries. After fixing the XSLT such cases dissapeared completely. Great. This would be a blocker for me. > 3) when several single index entries are used on consecutive pages, the > result 1,2,3,4,5 is produced. Is there any option to create a range > from this? I'm reconsidering this now. I designed my 'subject' index to use ranges when the subject is thoroughly explained, which obviously needs to define beginning and end. On the contrary, when the subject is just mentioned (above the threshold of importance), I inserted just a single index entry instance. Collecting these single instances into the range of e.g. 1-5 would bring false expectations that the subject is thoroughly explained there... This logic goes slightly against the case (1). When the range would be collapsed into to a single value, we would loose the info that the subject is described here. But it looks weird. Jan
