Re: [NTG-context] ConTeXt on the Mac (TexShop). Problem of a newbie
Hello Sietse, thank you for your proposal. I guess that there is not a lack of options here. However, my problem may be simpler than I had described in the first place. I am not so much concerned with using a specific slide layout (be it s-pre-05 or some fancy simple- or complexslide layout), but whether I want to use ConTeXt at all... ... and as life is already complicated enough ;-), my decision has more to do with usability and reliability than with the number of options. I am a software developer for more than 20 years now, so I know very well how easy it is to implement some bug in recently updated XYZ code as Hans had diagnosed my problem. But would it be possible to use ConTeXt without having to care about bugs in updated code or broken links between different modules...? So before turning to additional modules with additional questions like... - if I use simple- or complexslide , do I need to install the visualcounter-module before? - if so, is there a clear documentation of the required modules? ...

Re: [NTG-context] ConTeXt on the Mac (TexShop). Problem of a newbie
Hi Thomas, In your original post you stated that stated that you have be using LaTeX for your work. That would suggest to me that you are not proficient with TeX proper. ConTeXt runs, in my opinion, along the lines of TeX proper. That is you need intimate knowledge of TeX. Furthermore, you need a good background in ConTeXt and its use of Lua. These facts would have me advise you to not use ConTeXt. Furthermore ConTeXt is a moving target. That is, it is still in development. At least you can compare it to the early days of LaTeX2e. Things change fast, especially if you use the standalone, even though it is probably the best option. do not get me wrong ConTeXt is powerful and usable, but you really need to know what you are doing and what the modules really do. I assume I am in a similar position as you I prefer a LaTeX approach. Though ConText is quite advanced and interesting, it is too TeXian for me. I follow this list because I am interested to and using Lua(La)TeX. (Please ConTeXt group disregard my somewhat negative opinion of ConTeXt, just is not my cup of tee!) I noticed that you are using a MacBook Pro with OSX 10.6. My suggestion would be to use MacTeX and TeXLive 2012. It is most likely to give you more mileage. Furthermore try out LuaLaTeX. It gives you the advantage of using what you know and you can use Lua for doing things that are not that easy to do with LaTeX alone. Once you are comfortable with LuaLaTeX or LuaTeX then you may want to switch to ConTeXt. As a side note I am using a mid 2009 MacBook Pro 17 with OSX 10.8.2 and MacTeX/TeXLive 2012. Hope this helps. regards Keith Am 10.01.2013 um 09:13 schrieb Meigen, Thomas t.mei...@augenklinik.uni-wuerzburg.de: Hello Sietse, thank you for your proposal.

Hi Hans, I am kind of confused about the relationship between luatex and ConTeXt. The way I read the wikis and web sites luatex and ConTeXt are basically two different animals.

Schultz keithjschu...@web.de: I am kind of confused about the relationship between luatex and ConTeXt. http://www.tug.org/levels.html ConTeXt MkIV needs LuaTeX. That's a somewhat confusing description. (1) Context is just a format, so it should be mentioned as format. (2) We call all instances context, i.e. we don't combine engine names with 'context' so there is no 'pdfcontext', although one could do that. (3) As there are language dependent user interfaces, we have more formats (cont-en, cont-nl, ...). (4) We use a management script to run the engine with the context format. Reasons for this are: we need to manage multiple runs, we might need to call intermediate programs (in mkii for instance we need to sort indices). (5) This also permits us to present to user with an engine independent call to context. In mkii we had 'texexec' (on top of a more generic script manager called texmfstart), in mkiv we have 'context' (and again a script manager called mtxrun). Now, to come to luatex: this project is quite related to context as it all started in the context community. We also use context for testing and exploring new functionality. For this we use mkiv/mkvi which is a rewrite of context using the full potential of luatex so that we can go beyond what traditional tex engines can do. We explicitly have chosen for a lua + tex combination so that we don't have to hardcode solutions in the engine (macro packages have too many conflicting demands anyway) and are more future proof. Given that mkii is frozen, and given that type1 fonts are sort of obsolete (context has always been an early adopter of lm and gyre fonts), and given that utf is the way to go (so no messing with input and font encodings any more), and given some more reasons, in practice users will no longer use pdftex and/or xetex but luatex. In that sense context depends on luatex and also keep the development of that engine going. The philosophy of context is that by having most functionality in the core, users can rather easy create their own styles (the average style has not that many lines anyway). I'm always sort of puzzled when I see remarks that context is close to plain, as I cannot see where that conclusion comes from. The whole reason that context exists is that I didn't want to hack around in low level style files and deal with funny commands having @ in their names.

@Hans: yes, hbar is extremely common in quantum physics, in fact I'd go as
far to say as ubiquitous. It might be considered strange that the glyph
doesn't exist, but it's actually defined in TeX as a ligature:
\def\hbar{{\mathchar'26\mkern-9muh}
I tried defining this but it doesn't work: I still get nothing.
As it happens, \hslash seems to work fine, and in my opinion is a suitable
substitute so I will just
\def\hbar\hslash
(although actually that didn't work, I had to do \def\hbar{\hslash} for
some reason or I got an error in some tikz code I wrote).

Hans, This is a most lucid explanation. I have been waiting for this myself. To quote the great American philosopher, Corporal Radar O'Reilly, from the television show of the 1970s, M*A*S*H: Ah, Bark! [He was instructed to say Ah, Baaah! by Hawkeye Pierce] I apologise in advance for this most peculiar and culturally specific bit of history.

Schultz keithjschu...@web.de: I am kind of confused about the relationship between luatex and ConTeXt. http://www.tug.org/levels.html ConTeXt MkIV needs LuaTeX. That's a somewhat confusing description. (1) Context is just a format, so it should be mentioned as format. (2) We call all instances context, i.e. we don't combine engine names with 'context' so there is no 'pdfcontext', although one could do that. (3) As there are language dependent user interfaces, we have more formats (cont-en, cont-nl, ...). (4) We use a management script to run the engine with the context format. Reasons for this are: we need to manage multiple runs, we might need to call intermediate programs (in mkii for instance we need to sort indices). (5) This also permits us to present to user with an engine independent call to context. In mkii we had 'texexec' (on top of a more generic script manager called texmfstart), in mkiv we have 'context' (and again a script manager called mtxrun). Now, to come to luatex: this project is quite related to context as it all started in the context community. We also use context for testing and exploring new functionality. For this we use mkiv/mkvi which is a rewrite of context using the full potential of luatex so that we can go beyond what traditional tex engines can do. We explicitly have chosen for a lua + tex combination so that we don't have to hardcode solutions in the engine (macro packages have too many conflicting demands anyway) and are more future proof. Given that mkii is frozen, and given that type1 fonts are sort of obsolete (context has always been an early adopter of lm and gyre fonts), and given that utf is the way to go (so no messing with input and font encodings any more), and given some more reasons, in practice users will no longer use pdftex and/or xetex but luatex. In that sense context depends on luatex and also keep the development of that engine going. The philosophy of context is that by having most functionality in the core, users can rather easy create their own styles (the average style has not that many lines anyway). I'm always sort of puzzled when I see remarks that context is close to plain, as I cannot see where that conclusion comes from. The whole reason that context exists is that I didn't want to hack around in low level style files and deal with funny commands having @ in their names.

I did not check how they work, but since I didn't see any temporary files, the only possibility is to write the data to the tuc file, I assume. It is by any chance possible to provide a “method=block”? Yes, blocks are stored in the tux-file while buffers are only stored in memory. I played for a while with \setdataset to store the content but dropped it because it required multiple runs and especially in the first run the output would be always wrong That's no problem IMO. Two-pass data is always wrong the first run. In the worst case, it needs an additional run if text moves around too much. But since it's just another method, which is optional, this only applies if it's activated and then the user knows what he/she is doing and that it might be slower. I can consider it as a optional method. I think it would be a nice feature. It enables placement of elements where they logically belong, instead of where they are supposed to be printed. It's nothing mission critical though, but you can keep it in mind for a rainy afternoon. You can try the beta from my bitbucket site [0] which uses a two mechanism for named buffers (\startannotation[NAME] … \stopannotation) which can be accessed with \getannotation[NAME].

I don't believe that this is true, but I am most likely wrong.
Well, I think it was true in the beginning (as I remember a discussion
from Mojca on how to handle labels differently in the gnuplot module),
but clearly that is not the case now.
Indeed \blue text has worked, but 'draw T withcolor blue;' *should*
work as well.
The processing of textext() has changed recently, it seems.
The mkiv implementation has always been rather different from the mkii
one: text handling as well as dealing with colors.
\startMPcode
label(textext(I'm seeing double),origin) withcolor green ;
label(textext(I'm seeing double),(-1mm,1mm)) withcolor blue ;
\stopMPcode
DOES work.
Of course, these are much simplified minimal examples of what I would
like to do.
Minimal example to show what is happening:
\startbuffer[initialize]
picture T;
T := textext(Hello);
picture Q;
Q := T;
\stopbuffer
\startbuffer[T]
draw T withcolor blue;
\stopbuffer
\startbuffer[Q]
draw Q shifted (-1mm, 1mm) withcolor red;
\stopbuffer
\startlines
Only draw T: \processMPbuffer[initialize,T]
Only draw Q: \processMPbuffer[initialize,Q]
Draw T Q : \processMPbuffer[initialize,T,Q]
Draw Q T : \processMPbuffer[initialize,Q,T]
\stoplines
You and Alan can pick up the beta from the ftp server and play with this:
\setupbodyfont[dejavu]
\starttext
\startMPpage[offset=10pt]
picture MyText ; MyText := textext(Dummy) ; % not used later on
picture MyText ; MyText := textext(\red Red) ;
draw MyText ;
draw MyText scaled 2 shifted (0,-1cm) ;
draw MyText scaled 3 shifted (0,-2cm) ;
picture MyText ; MyText := textext(Blue Green Red) ;
draw MyText rotatedaround(center MyText,10) shifted (0,-3cm)
withcolor blue ;
draw MyText shifted (0,-4cm) withcolor green ;
draw MyText rotatedaround(center MyText,-10) shifted (0,-5cm)
withcolor red ;
picture MyText ; MyText := image (
draw textext(Green Red Blue {\yellow YELLOW} Whatever 1) ;
draw textext(Green Red Blue {\yellow YELLOW} Whatever 2)
shifted (10cm,0) ;
) ;
draw MyText shifted (0,-6cm) withcolor green ;
draw MyText shifted (0,-7cm) withcolor red ;
draw MyText shifted (0,-8cm) withcolor blue ;
\stopMPpage
\stoptext
The complication is that we reuse a picture which once defined has
frozen properties. However, after hours of lua/tex juggling I managed to
made a variant that better keeps track of applied colors. I'm not sure
if this is foolproof but it's probably quite ok for what Alan wants to
do. Although ... being a scientist he will look for the next frontier
... (or even more scientific: try to prove me wrong).
