Re: [NTG-context] splitting table cells/rows

[Erik Margraf]

As far as I experienced, it does split the table, but only at row borders.
Not within a row, as
the word example. Tabulate does this kind of splitting. For my usecase,
this was enough, though
the other table environments have some goodies which the tabulate
environment misses ...
(But maybe these features - e.g. combining cells - are the reason why the
splitting of cells doesn't
work ...)

Erik

Thanks, this works quite good for me!

Re: [NTG-context] help on def & buffer

[Erik Margraf]

Than you Hans!
My plan is simply to use the output of a sagemath run in this way. A run
should produce
several files containing TeX code. I only wanted to shorten the
\startbuffer \input ... \stopbuffer
sequence. Maybe this (including sagemath output) could be done differently,
but this was
the first (and only ;-)) idea I came up with.

Dear List,

is it possible to achieve the following:

Second section
 Some Text

Table of Contents
1 First section
2 Second section

I tried both:

a) \setuphead[section][sectionnumber=no]

b) \setupheads[sectionnumber=no]


I also tried

\setuphead[section][number=no]

This gave me sections without numbers, but als a ToC without numbers

[NTG-context] typefile with absolute path to file

[Erik Margraf]

Dear List,

a question about \typefile{}.
I tried to use \typefile{ /with/an/absolute/path/to/some_file }  and failed
Message in the log: Verbatim some_file not found. Also tried with
no path at all, assuming it will take the file from the current directory.
Same result.

Do I miss something? Should this work? Or, if not, how can I achieve
this effect (typefile
with absolute path to a file. btw. on a Linux system)

I'm aware of a similar message thread to this list from May 25th, this year.
But I didn't feel that it speaks against my comprehension of \typefile ...

Thanks!

Hi,

Thanks Aditya!

I tried this again with

\starttext
   \typefile{/tmp/xxx.tex}
\stoptext

and could trace what's going on ... (not even /tmp/xxx.tex worked)

The lines below is the trace output belonging to /tmp/xxx

stat(tmp/xxx.tex, 0x7fff5dc73d90) = -1 ENOENT (No such file or directory)
stat(../tmp/xxx.tex, 0x7fff5dc73d90)  = -1 ENOENT (No such file or directory)
stat(../../tmp/xxx.tex, 0x7fff5dc73d90) = -1 ENOENT (No such file or
directory)
stat(tmp/xxx.tex.tex, 0x7fff5dc73d90) = -1 ENOENT (No such file or directory)
stat(../tmp/xxx.tex.tex, 0x7fff5dc73d90) = -1 ENOENT (No such file
or directory)
stat(../../tmp/xxx.tex.tex, 0x7fff5dc73d90) = -1 ENOENT (No such
file or directory)

I could verify that tmp/xxx.tex is actually found!
current version: 2012.11.16 23:51
Anything I can do about that?  (I guess I can work with relative paths
below - tested this ...)

Context Version: current version: 2012.11.16 23:51

That's interesting. As I could trace, the leading / is removed on my system.

lua -v gives:  Lua 5.1.5  Copyright (C) 1994-2012 Lua.org, PUC-Rio

Though, I have lua5.2 installed in parallel

Any other infos, which might help?

Re: [NTG-context] Colors: printing vs. on screen

[Erik Margraf]

Thanks! I'll go for the calibration and some trials in CMYK colors for
printing.

kind regards
Erik

2011/6/19 Henning Hraban Ramm hra...@fiee.net

 Yes, because your monitor uses RGB and your printer uses CMYK. The
 conversion between thetwo is not too complicated, but actually getting the
 same output from the two is hard. RGB is an additive model, CMYK is
 subtractive (read about the different models, wikipedia will do). The color
 impression you get by looking at the output is generated in completely
 different ways.


 Most office printers cope well with RGB (sRGB) colors, a lot of inkjet
 printers even better than with CMYK colors, because they're optimized for
 home dummy use.

 But (as Christoph pointed out) your printer can be as great as it goes,
 you'll never get a similar color impression if your monitor's set to some
 extreme setting - and most monitors that I saw outside of the graphical
 branch are set to nonsense settings, e.g. max contrast.

[NTG-context] Colors: printing vs. on screen

[Erik Margraf]

Dear List,

I defined the following color for one of my
documents: \definecolor[P][r=0.64,g=0.22,b=0.27]
When I printed this document on a probably typical office laser printer (a
Canon iRC), the
colors didn't match. (not even close and I didn't like the printed
color) This is probably no real
surprise, but can anybody provide some insight or hints to information on
these matters to me:

 -- Are spot colors the thing to use to get a grip on these matters?
 -- Is this generally only a matter of color spaces and transformations
between them?  or ...
 -- Is this also dependent on specific printer models (eg. different office
laser printers)?
-- If yes, is there any source on information on the pecularities of
these printers?

kind regard and thanks

Erik

Re: [NTG-context] Second Try for help using Windows 7 Winedt 6.0 MiKTeX 2.9 to process ConTeXt

[Erik Margraf]

I used TeXworks, which was included in the MikTeX distribution with
the configuration shown  in the screenshot. Rather minimalistic,
but worked and may be a start.

regards
Erik

2010/11/19 barndog1...@gmail.com

 Perhaps Taco could find time to explore this??

 Recently MikTeX enabled ConTeXt using Luatex .60.

 I love ConteXt and was using it UNTIL MiKTeX stopped support in version
 2.8.

 I try to process a ConteXt file now using:

 Windows 7, Winedt 6.0 and MikTeX 2.9...

 I changed to MKIV within MikTeK and luatex tryies to process a TIK test
 file instead of my master.tex file.

 Could anyone please advise me on how to get this working? I reallly NEED to
 use ConTeXt again to continue to publish my research correctly

 Thanks

 I had the same error. I am on linux-64 and the luatex binary in
 linux-64/bin did not have the execute permission set. So the wrong luatex
 was being used.

 But I use mtx-update directly, so do not know if this is the same reason
 for the error in the minimals.

Re: [NTG-context] Animations (again, but different)

[Erik Margraf]

Hi, with context version  2010.11.12 18:22, I get much
better results now. Thanks!
I guess, I now have a first feeling about
these things.

Erik

2010/11/11 Erik Margraf erik.marg...@googlemail.com

 Thank's for your example! But I'm sorry to say, I didn't get it.
 When I run context on it, it results in a 2x2 matrix of pictures.
 Two of them show some reaction (change the color somewhat)
 when I click on them. (the cows don't). That's all.

 Maybe it has to with the following lines in the log file:
 ...
 interaction : active
 references  : unknown reference [][VideLayer{1}]
 references  : unknown reference [][VideLayer{2}]
 references  : unknown reference [][VideLayer{3}]
 references  : unknown reference [][VideLayer{4}]
 ...
 I tried the following example from the Wiki:
 ===
 \defineproperty[my-hasitations][layer][state=stop]

 \startproperty[my-hasitations]
 To \ConTeXt\ or not to \ConTeXt?
 \stopproperty

 \button{Show   Decision}[VideLayer{my-hasitations}]
 \button{Hide   Decision}[HideLayer{my-hasitations}]
 \button{Toggle Decision}[ToggleLayer{my-hasitations}]
 
 This produces the analogous messages for these three buttons.

 Hi,

 I uploaded a new beta (so the minimals will have it in about an hour):

 - some cleanup at the lua end as side effect of documenting lua interfacing
 as part of writing the cld manual

 - a couple of bug fixed in the lua code that crept in during some
 optimizations

 - removal of some old lua code (not needed any more or replaced by better
 code)

 - a couple of patches (or extensions) to macros (due to reports on the
 list); for instance, the HideLayer and VideLayer reference actions were
 never implemented; also, some animation code has been added (for WS)

 - definitions like \definedfont[file:lbr.pfb] are ok now (remapped onto
 afm, a few line harmless extension)

 - a replacement of the existing marking mechanism (as used for running
 headers and footers): less interference with typesetting as mark nodes are
 no longer part of the game; more robust synchronization of chained marks
 (sectioning); more robust handling of marking in columns and columnsets;
 experimental marking in arbitrary constructs (thomas might like that one);
 not all is tested but we have:

 the usual marking: first, last, previous, current; these are strict in the
 sense that they take sectioning into account

 some new, less strict marking: firstpage, lastpage, previouspage; these
 ignore sectioning related resets

 some experimental methods: next, nextpage; these concern parts of
 paragraphs that end up on the next page, so limited lookahead (in there is
 interest we can make that full lookahead i.e. future marks)

 the usual column related marking:

\getmarking[chapter][first]/
\getmarking[chapter][page][first]/
\getmarking[chapter][column:first][first]/
\getmarking[chapter][column:1][first]/
\getmarking[chapter][1][first]

 even more expermental:

  \definemarking[boxmark]

  \setbox0\ruledvbox{
\marking[boxmark]{tufte} \input tufte \par
\marking[boxmark]{ward}  \input ward  \par
  }

  \synchronizemarking[zerobox][0] \box0

  \getmarking[boxmark][zerobox][first]
  \getmarking[boxmark][zerobox][last]

 anyhow, it might be that something is broken, but at least this
 implementation has more potential

 - the properties mechanism is obsolete and replaced by three mechanism that
 used them (originally properties dealt with specific engine/backend
 functionality); the most important ones are

 \defineviewerlayer[name][options]
 \startviewerlayer[name]\stopviewerlayer
 \viewerlayer[name]{...}

 and

 \defineeffect[name][options]
 \starteffect[name]\stopviewerlayer
 \effect[name]{...}

 where we have predefined (as with former properties):

 \defineeffect [inner]   [alternative=inner,rulethickness=.25pt]
 \defineeffect [outer]   [alternative=outer,rulethickness=.25pt]
 \defineeffect [both][alternative=both, rulethickness=.25pt]
 \defineeffect [normal]  [alternative=normal]
 \defineeffect [hidden]  [alternative=hidden]
 \defineeffect [stretch] [alternative=stretch,stretch=1]

 the properties commands are still there but map onto these so older code
 should work ok (but somewhat less efficient)

Dear All,
the small example attached behaves in mkii (texexec) as expected.
The string CONTEXT as well as a little square are colored. Using
mkiv (context) only the little square is colored. The CONTEXT
string is black.
Tested on two different linux systems, both 64 Bit.

Re: [NTG-context] Clipping of text (or something equivalent)

[Erik Margraf]

Thanks!! For the hints to existing examples as well as for the
very instructive advice to clip to the enlarged unitsquare.

2010/6/7 Hongwen Qiu qiuhong...@gmail.com

  于 2010年06月07日 22:47, Erik Margraf 写道:

 Hi all,
 I'd like to achieve in context something like I did in
 the attachment (context.pdf). My idea was (and
 that's the way how I did this in Inkscape):

- Create Text
- Double the text
- Clip one for the upper half, clip the other for the lower half

 Actually, you only have to clip one, either the upper half or the lower
 half, since the latter elements added onto the canvas will mask the former
 elements.

- Connect the two halves.

 My (probably naive) approach to clipping text in context was:

 -
 \starttext
 \startuniqueMPgraphic{context}
   draw btex \bf Context etex xyscaled (4.0, 4.0) withcolor .8white ;
   clip currentpicture to unitsquare;

 take something like:
 clip currentpicture to unitsquare scaled 8cm;
 and you'll know what's the problem.

 \stopuniqueMPgraphic
 \null\dontcomplain
 \uniqueMPgraphic{context}
 -

 (Without the clip - line, the string Context is displayed. With
 clipping, nothing is displayed.)

 Any hint in the right direction towards clipping or maybe a better
 way to achieve this is appreciated.

 Thanks

 Erik

[NTG-context] Shaped paragraphs

[Erik Margraf]

Hi,
I have some problems using shaped paragraphs. I tried to follow
the procedures described in METAFUN in the chapter about
talking to TeX. The output I get from running context
(latest minimals) is wrong (or at least unexpected ;-).
The shape of the text paragraphs doesn't match the
backgrounds.  They are interchanged. If I comment out any
single shape production it works.

My Example (hope, it's near to minimal) is attached

kind regards

Erik

Based on the pretty printer in the wiki, I wrote my own.
If I understood you well, you want a b/w pretty printer
with reserved words bold. The pretty printer is capable
of doing both. An example is attached. Probably missing
is the functionality to control the typesetting of reserved
words in TeX. This is done in the lua code. I didn't mind
up to  now. Any feedback is welcome.

   I use context 2010.01.26 Mk IV or texexec
  well, I'm working to a pretty-printer for Python with low priority

 Attendo ;-)

[NTG-context] Pretty Printing Python code

[Erik Margraf]

Hello all,
I wanted to typeset some Python code and stumbled across the
pretty printing feature of ConTeXt. So far, I think I've learned the
following:

   -- There's no pretty printer for python. Neither in MKII nor in MKIV
   -- The wiki has an example implementation for a python pretty printer
  for MKII, i guess.

I decided to play a little bit with pretty printing (maybe implement a
Python pretty printer on my own) and failed at the start ;-)
I tried the following:
  -- Copied the filename pret-lua.lua to pret-py.lua
  -- Added a print statement to verify that the respective lua
code (pret-lua.lua, pret-py.lua) is actually called.
When I ran context on the file below, I could see that pret-lua.lua
had been called, but pret-py.lua had not.  I guess, I did wrong something
very fundamental.

Thanks in advance for any hint

Erik Margraf

[NTG-context] Some question regarding Layers

[Erik Margraf]

Hi all,
i have two questions regarding the use of layers.

 -- Is there an easy way to position a layer in the middle of the page.
My intent is to position some kind of graphic/picture there.
I usually try to wrap the picture in a hbox to \paperwidth {\hfil
\externalfigure{} \hfil} and then
wrapping the hbox in a vbox
 -- Is there a better way to achieve this?
 -- How to do that with layers?

-- Is it possible to define and position layers in one Macro. I have
something like the following
   in mind (untested):

   \define[1]\MLayer{
  \definelayer[#1]
  \setlayer[#1][state=start]{\externalfigure[#1]}
}
My experience so far is, that it's necessary for a layer to appear that
it is listed in pagebackgrounds
ist this true? With this it seems, that a macro like that above is
impossible, true?

thanks in advance for your help

Erik

[NTG-context] Overlays with metapost

[Erik Margraf]

Hello,
is it possible to achieve an overlay effect with metapost like
in the attached picture (a photo and a pin in the upper left corner)?

I could load both images but I can't control the position where
the pin is inserted.

Is this possible by other means?

thank you!

Regards

Erik
