[NTG-context] letter: How to customize reference line?

2018-06-25 Thread Paul Menzel

Dear ConTeXt folks,


I am trying to customize the reference line in a letter.

```
$ context --version

mtx-context | ConTeXt Process Management 1.01
mtx-context |
mtx-context | main context file: 
/usr/share/texmf/tex/context/base/mkiv/context.mkiv

mtx-context | current version: 2017.05.15 21:48
```

The example from Wolfgang’s `correspondence.pdf` [1] doesn’t work for me.

```
\setupletter
  [name={Joe User},
   date=\currentdate]

\setupletter
  [list={name,date}]
```

Only the date is shown in the reference line.

The solution from chapter 9 also does not work. Still only the date is 
shown.


```
\setupletter
  [name={Joe User},
   date=\currentdate]

\setupletterstyle[reference][list={name,date}]
```

Do I need to create a new customized reference line to add other fields 
next to the date to the reference line?



Kind regards,

Paul

Looking at `letter-imp-dinb.mkiv` [1] I finally figured that the
following does what I need.

\setupletterlayer
  [topmark,botmark,cutmark]
  [state=stop]

As a side node, I am still wondering why the name is `cutmark`. Cleary,
no scissor is used to cut the letter in half. Should it be punchmark,
because that is the mark to align the whole puncher(?) to?

[NTG-context] correspondence: Wrong version string in module?

2012-08-25 Thread Paul Menzel
Dear Wolfgang,


looking at the version string of the a module `letter-imp-knuth.mkiv` I
think the version string is incorrect.

 Y'know, Hans and Wolfgang having time travel powers would explain an
 awful lot.

Did not think of that. But now that you mention this, this sounds
reasonable. ;-)

 The inhuman speed of development ... the instantaneous
 answers ... and that haunting feeling, impossible but inescapable,
 that ConTeXt is bigger on the inside.

[NTG-context] KOMA-srcartcl Type Area: How to count header and footer to text area?

2011-12-13 Thread Paul Menzel
Dear ConTeXt folks,


having heard nice things about the KOMA script type area I wanted to use
it too and tried out the example in the Wiki [1].

% Set binding correction value (mode=BCOR turns it on).
\doifmodeelse{BCOR}{\def\bindingcorr{3mm}}{\def\bindingcorr{0pt}}

% Set visible page width.
\newdimen\PageWidth
\PageWidth=\dimexpr(\paperwidth-\bindingcorr)

% Determine the paper aspect ratio.
\edef\Ratio{\withoutpt{\the\dimexpr(2\paperheight/(\PageWidth/32768))}}

% Set the textarea width to 2.6 alphabets.
\setbox\scratchbox\hbox{\dorecurse{26}{\character\recurselevel}}
\newdimen\Width \Width=\dimexpr(2.6\wd\scratchbox)

% Set the textarea height proportional to the width.
\newdimen\Height \Height=\dimexpr(\Ratio\Width)

% Set the margin/gutter widths to be equal on a full spread.
\newdimen\Back
\doifmodeelse{oneside}
{\Back=\dimexpr(((\PageWidth - \Width) / 2) + \bindingcorr)}
{\Back=\dimexpr(((\PageWidth - \Width) / 3) + \bindingcorr)}

% Set the top and bottom margins in a 1:2 ratio, ignoring headers.
\edef\Top{\the\dimexpr((\paperheight - \Height) / 3 - 3\lineheight)}

% Redefine \Height to include header and footer space.
\Height=\dimexpr(\Height + 8\lineheight)

% Set up the page layout using the calculated parameters.
\setuplayout[
 backspace=\the\Back,
 height=\the\Height,
 width=\the\Width,
 header=2\lineheight,
 headerdistance=\lineheight,
 footer=2\lineheight,
 footerdistance=3\lineheight,
 topspace=\Top]

\starttext
\framed[width=\textwidth,height=\textheight]{}
\stoptext

I only want to add a page number to the footer [3] and I do not want to
use any header [2, and ConTeXt manual]. Therefore I set

\setupheader[][state=none]
\setuppagenumbering[alternative=doublesided, location={footer}]
\enablemode[BCOR]

According to the KOMA-Script manual [4] having just a page number in the
footer it should be counted as belonging to the margin. The only way I
found out to achieve that was setting `\footdistance=0`.

Is that the “correct” way to comply with the KOMA-Script type area
recommendation?

Please find the adapted example attached.


Thanks,

Paul

[NTG-context] How to create horizontal line for signature?

Dear ConTeXt folks,


sometimes you need to insert a line for signature. I could not find

The down side is, that its widths is not perfectly aligned with the

I guess there is something simpler to do it. I looked at Wolfgang’s
letter module but could not figure out how it is done there.

Something like the examples posted for LaTeX on Stack Exchange [3] for

 The module doesn’t draw a rule for the signature.

As always thank you so much for the fast answer. I am always a bit
reluctant to use tables for this, thinking of it only as displaying data
with a table. This is from back in the HTML days were tables were used
for formatting. But I guess tables are perfect for aligning things.

  I only want to add a page number to the footer [3] and I do not want to

 \setupheader[][state=none]
 \setuppagenumbering[alternative=doublesided, location={footer}]
 \enablemode[BCOR]
  
  According to the KOMA-Script manual [4] having just a page number in the
  footer it should be counted as belonging to the margin. The only way I
  found out to achieve that was setting `\footdistance=0`.
  
  Is that the “correct” way to comply with the KOMA-Script type area
  recommendation?
  
  Please find the adapted example attached.

 Have you seen http://modules.contextgarden.net/typearea

Yes I did. But it does not seem to provide all options like
`headinclude` or `footinclude`.

At least

\usemodule[typearea]
\setupTypeArea[bcor=0mm, headinclude=false, footinclude=false]

did not change anything.

[NTG-context] Lua and module gnuplot: Manipulate Gnuplot script with Lua

2011-12-12 Thread Paul Menzel
Dear ConTeXt folks,


I have two coefficients saved in a text file

-0.157737135681261
-0.211443105668896

and I want to use them to plot a line with gnuplot.

Having several of those files I want to use Lua to create the formula
for the line for me.

I have not yet figured out how to read values from a file in Lua and
just tried to print a constant to the gnuplot command.

I tried the following.

\usemodule[gnuplot]

\startGNUPLOTscript[lua]
   plot \ctxlua{context(1.2 * x + 3)}
\stopGNUPLOTscript

\startGNUPLOTscript[nolua]
   plot 1.2 * x + 3
\stopGNUPLOTscript

\starttext
\useGNUPLOTgraphic[lua]

Above should be a plot.

\useGNUPLOTgraphic[nolua]

\blank
\CONTEXT\ \contextmark\ \contextversion
\stoptext

But only the second plot done and for the first the following error is
shown.

mtxrun  |

mtxrun  |
mtxrun  |
   plot \ctxlua{context(1.2 * x + 3)}

Is there a way to manipulate gnuplot scripts with Lua?

 This won't work. The reason is that contents between
 \startGNUPLOTscript and \stopGNUPLOTscript are not parsed by ConTeXt
 on purpose.
 
 It was very very very painful if not impossible to get it right with
 parsing. I often do things like
 \def\E#1{$10^{#1}$}
 
 \startGNUPLOTscript[name]
 set logscale y
 set format y \\E{%T}
 plot sin(x) t '$\sin(x) [\E{3}]$' # usually something else with
 logscale, but just to show the point
 \stopGNUPLOTscript
 
 and if ConTeXt starts parsing this it becomes a pure nightmare.
 Realize that it can easily happen that ConTeXt then writes out
 set logscale y
 set format y some junk leftovers from \\
 Eungrouped { since % starts comment
 plot sin(x) t '\math{\mathrm{sin}(x) [{10^{3}}]}' arbitrary junk
 from expansion ...
 
 
 
 However, \startGNUPLOTinclusions is parsed and you could in theory
 misuse that, but it would be very bad coding practice.

Thank you very much for your explanations.

 It would be a lot better to come up with some proposal how to change
 the interface to enable what you want to do. (To be honest, it is
 still on my todo list to migrate to Aditya's filter module in the
 background, but I don't find the courage to start since I have no idea
 how many bugs will creep in.)

I do not know this very well, so I do not know what would change when
using the filter module. I guess in the end being able to pass a
plt-file to `\startGNUPLOTscript` would be enough.

 But a serious question: what *exactly* do you want to do with lua that
 you are unable to do with some (even though ugly) gnuplot trickery?

I do not know. This was just a product out of my ignorance. Searching
for `gnuplot load parameters` or something like that only turned `fit`
related stuff.

Thinking about this, I should have searched harder or looked at the
manual or examples.

 Gnuplot does have some basic programmable capabilities. I can imagine
 that you should be able to do something like:
 
 # params.dat
 a=-0.157737135681261
 b=-0.211443105668896
 
 \startGNUPLOTinclusions
 f(x,a,b)=a*x+b
 \stopGNUPLOTinclusions
 
 \startGNUPLOTscript[name]
 load 'params.dat'
 plot f(x,a,b)
 \stopGNUPLOTscript

 And if needed you can create params.dat on the fly (but I believe that
 the same should be doable even if you start with just pure data values
 and do some dirty tricks in gnuplot).

That pretty much what I need. Thank you!

What I do is to do simulations and then do the linear regression using R
[1]. (I know gnuplot can do that too, but I got some errors with it and
using R seems easier for me.) Then the calculated coefficient are saved
to a separate file because having discovered your nice gnuplot module I
want to use that for plotting. Now I need to read in those parameters. I
guess I have to compose the plot manually but those parameters were
essential.

 Yet another trick could be to create a text file on the fly with lua
 (if you really really really need that) and then your script only says
 something like.
 
 # bla.plt created on the fly with lua scripts
 plot 1.2 * x + 3
 
 \startGNUPLOTscript[bla]
 load 'bla.plt'
 \stopGNUPLOTscript
 
 I leave creating a suitable 'bla.plt' with lua to others ...

That is in my opinion the best solution. If I want to script something
there are enough solutions already. Being able to use the tools of once
choice and to insert the result should fit everyone’s need.

Thank you again very much for your help.


Thanks,

Paul

I just wanted to bring this topic up again since it is still
reproducible with ConTeXt MKIV 2011.11.25 21:29.

 However the character ∫ looks the same as \intop and ∫\nolimits looks
 the same as \int.

Yes, it does.

 As to why \intop looks so weird, I have no idea. If you add
 \usetypescript[modern-base] \setupbodyfont[modern]
 it will work ok. Cambria Math also results in two different heights of
 the operator depending on whether limits are there or not. It might be
 a bug somewhere in virtual font setup of LM. In pdfTeX \int and \intop
 operators are positioned equally.

Using XITS it does also work although in display math mode(?) ∫ and
$\intop$ are not scaled.

I use the following example.

\setupbodyfont[xits]

\setupinteraction[state=start]

get the following error.

[NTG-context] gnuplot: `! Undefined control sequence.` with format specifier %

2011-12-11 Thread Paul Menzel
Dear Mojca and ConTeXt folks,


I compiled gnuplot 4.5 from source (master) and got everything running.
Mojca, thank you so much!

Trying the example from the gnuplot page in the Wiki [1]

\usemodule[gnuplot]

\setupGNUPLOT[terminal=mp,option=color]

% general settings for the whole document
\startGNUPLOTinclusions

   # you may use TeX commands to format the titles and axes
   set title '\bf Trigonometry'
   set xlabel '$x$'
   set ylabel '$y$'
   set format y '\%.1f'
\stopGNUPLOTinclusions

\startGNUPLOTscript[tan]
   plot tan(x) t '$\tan(x)$'
\stopGNUPLOTscript

\startGNUPLOTscript[sin]
   plot 4*sin(x)+x t '$4\sin(x)+x$', x t '$x$' lt 3
\stopGNUPLOTscript

\useGNUPLOTgraphic[tan]
\useGNUPLOTgraphic[sin][width=10cm]

even with the comments removed as above I get the following though.

I hope that is not related to the used ConTeXt version.

 This should have been without the backslash.

 In beginning the text was processed with TeX, not it is taken
 literally (% doesn't start the comment any more), so maybe it's a
 leftover from the very early days. I will check the wiki.

I see. Thank you. It does not complain anymore.

  Actually I hope that it is since then upgrading would fix my issue. ;-)
 
 ... however I still have some problems. For some reason ConTeXt only
 generates dvi files from metapost code which has never been the case
 before. I need to figure out what is going on.

I am also getting other errors now and even moving the ConTeXt file to a

 But one question. Why do you say that you compile the latest source of
 gnuplot (which finally has context terminal built in, after 5 or 6
 years), and yet you use the mp terminal instead of the default
 context (or at least tikz)? The mp terminal has been there
 forever, and hardly ever improved. It also doesn't integrate too well
 (if you change the typeface, that won't be reflected in you plots).

Thank you for the follow up. I just blindly copied the example from the
Wiki and did not pay any attention. In my thesis, I of course use the
ConTeXt terminal.


Thanks,

Paul


PS: Do you have a BibTeX entry for your gnuplot module?

 What is the thesis going to be about?

The topic is how long integrated random walks stay positiv. Not being
able to prove that formally for double-integrated(?) random walk, I am
doing some simulations.

 (I just noticed that mptopdf complains about missing bibtex files. :)

It seems to work for me.

  PS: Do you have a BibTeX entry for your gnuplot module?
 
 Do you suggest me to publish an article about the terminal in arXiv,
 to get at least some citations by the time when I need to submit my
 thesis? :P

That is an idea. ;-)

 But no, I don't have it. I could try to create one though, but I'm not
 even sure what the webpage should be. Many scientific programs just
 ask to cite their first article in some scientific journal if one uses
 the software, but I neither have an article nor homepage apart from
 that (still outdated) wiki page.
 
 There is some additional documentation on
 https://github.com/mojca/context-gnuplot/tree/master/texmf/doc/context/third/gnuplot
 (possibly also in minimals, but I'm not sure when I last synced the
 version), but even that is outdated now since they required from me to
 strip down terminal options parsing code.

I thought asking does not hurt. ;-) So I guess I will just reference
ConTeXt and gnuplot then.


Thanks,

Paul

As far as I can see, the file is still the same in the ConTeXt beta.

Could you update the file by either applying the attached patch or

[NTG-context] Bibliography: Setting `alternative=` without `criterium=all` displays nothing (ConTeXt: 2011.11.25)

Dear ConTeXt folks,


using

ConTeXt  ver: 2011.11.25 21:29 MKIV  fmt: 2011.11.25  int: 
english/english

and the following minimal example (attached too)

\setupbibtex[database=sample, sort=author]
\setuppublications[alternative=ada] % Show reference numbers in the 
generated list.
\starttext
As \cite[hh2010b] already indicated, bibtex is a \LaTeX-centric program.

\CONTEXT\ \contextmark\ \contextversion

\completepublications
\stoptext

the references are not displayed. Not specifying `alternative` or adding
`criterium=all` (`cite` does not work either) displays the references
again.

Could someone please confirm this with a recent ConTeXt version?


Thanks,

Paul

[NTG-context] Bibliography: Any styles including URL?

2011-12-10 Thread Paul Menzel
Dear ConTeXt folks,


type setting my thesis with ConTeXt I still use BibTeX to manage my
references. Since a lot of references are available online I want to
include the URL if they are available.

I read the ConTeXt publication module documentation [1] and as far as I
can see, there are some predefined layouts included in ConTeXt but none
of them seem to include the URL when passed.

The Bibliography documentation [1] also mentions that setting this up is
tedious. So I am hoping I can profit from someone else’s work and use
it. Could someone share such a style please for a mathematical thesis in
German? That would be much appreciated.


Thanks,

Paul

[NTG-context] Bibliography: How to get `\completepublications` to use different title?

2011-12-10 Thread Paul Menzel
Dear ConTeXt folks,


reading the Wiki page [1] and the documentation [2] I could not find a
way to change the default used `\chapter` [3] to `\subject` which I
need, because the references have to be set without a number and my
“highest” level is `\section` otherwise.

Is there something similar to `\setupheadtext[en][pubs=References]` for
other settings? I do not know how the publication-enviroment(?) is
called.

\setupbibtex[database=sample, sort=author]
\setuppublications[alternative=apa, criterium=all] % Show reference 
numbers in the generated list.
\starttext

\section{Example}
As \cite[hh2010b] already indicated, bibtex is a \LaTeX-centric program.

Re: [NTG-context] Keep struggling with old style numerals!

2011-12-08 Thread Paul Menzel
Dear Gerard,


Am Donnerstag, den 08.12.2011, 10:56 +0100 schrieb Verhaag, G.C.H.M.:

 A few days ago I installed the latest ConTeXt version but now my 
 oldstyle settings don't seem to work any more!

what version did you use before?

 I use the following settings in my preamble:
 
 \usetypescript[schola]
 \setupbodyfont[schola,10pt]
 
 \definefontfeature [oldstyle] [default] [onum=yes]
 \addff{oldstyle}
 
 Perhaps something changed that I missed! Thanks in advance!

Do you get an error message or are the settings just not applied? An
output file from a working ConTeXt version and one from the current one
would be nice too.


Thanks,

Paul

[NTG-context] MetaFun: Is the maximum of `vloggrid` limited to 10?

But the width parameter should prevent that, should not it? In this case
10 cm?

Re: [NTG-context] Math align in mkiv

Dear Otared,


Am Mittwoch, den 07.12.2011, 05:11 +0100 schrieb Otared Kavian:

 Thank you having tested the file I sent.

did the example work for you with MKIV in the past?

 As I suspected, your testing confirms that the change or the bug has been 
 introduced in a recent version of ConTeXt mkiv, some time between October and 
 late November.
 The version I am running is
   ConTeXt  ver: 2011.11.29 23:11 MKIV  fmt: 2011.12.2  int: 
 english/english

I can also reproduce that behavior using

ConTeXt  ver: 2011.11.25 21:29 MKIV  fmt: 2011.11.25  int: 
english/english

 I think at some time in November Hans did some changes in math alignment 
 after someone reported a bug, and Aditya said he wouldn't have time to (or 
 could not) fix it.

There were two issues and the corresponding messages in the archive
[1][2]. So if these are related it should work for you using the version
from November 24th.


Thanks,

Paul

[NTG-context] `\{start, stop}MPpage`: MetaPost figure does not fit canvas(?) in resulting PDF file

2011-12-07 Thread Paul Menzel
Dear ConTeXt folks,


using the following example

\starttext
\startMPpage
draw (0,0)--(10,10)--(15,5)--(20,10);
draw (0,0)--(0,10)--(10,10)--(10,5)--(15,5)--(15,10)--(20,10) withcolor 
blue;
\stopMPpage
\stoptext

it looks like the bottom is not included in the resulting PDF file and
at the top there is too much room. (So it looks like the figure is moved
too far to the bottom.)

Using the examples from the Wiki [1] with circles works though.

I am using ConTeXt Standalone.

are you subscribed to the list? If yes, have you set up to get the

In either way, when participating in a discussion it is a good thing to
subscribe [1] and then configure the list to send you all messages. Then
you can reply to the list like you are used to and the threading is
kept.

To get the reference you can also download the archive as a mbox file

[NTG-context] Title page for diploma thesis

2011-12-03 Thread Paul Menzel
Dear ConTeXt folks,


I am trying to format the title page for a diploma thesis. Looking at
the Wiki most of the title or cover pages just have the title centered
and maybe a subtitle right below [1].

\starttext
\definemakeup[titlepage][align=middle]

\starttitlepagemakeup
{\definedfont[Serif at 20pt]University}
\blank[big]
{\definedfont[Serif at 20pt]\sc Institute}
\vfill
{\definedfont[Serif at 20pt]Diploma thesis}
\blank[big]
{\definedfont[Serif at 30pt] \setstrut \strut Interesting topic}
\vfill
by John Doe
\stoptitlepagemakeup
\stoptext

1. Is using `\blank` the recommended way to format the page? Or is using
boxes and placing them manually “better”?

2. Looking at the output it is not centered exactly and a little bit to
the left. Why is this the default? Does anyone know? Looking at the
manual [2] in chapter page design (p. 29, screen version) this seems to
be the backspace value. Is there an easy way to center it according to
the whole paper width? Additionally I would have guessed it to be more
on the right when glueing or trussing up(?) (German binden) the pages.


Thanks and I am sorry for the sleight off-topic second question,

Paul

[NTG-context] Define `\luatexversion` similar to `\contextversion`

2011-12-03 Thread Paul Menzel
Dear ConTeXt folks,


thanks to Robin’s example documents I found out about the following last
two commands

\Context\ \contextmark\ \contextversion

allowing to put the used components and versions into the document.

Then I found `\luaversion` to display the version of Lua. But I could
not find `\luatexversion`. Is there something similar? Can this command
be defined?


Thanks,

Paul

[NTG-context] Fractions and binomial inlined in text ($n \choose \frac{n}2$): Parentheses not scaled

2011-12-03 Thread Paul Menzel
Dear ConTeXt folks,


using the following minimal example

\starttext
Using \type{\choose} in text $n \choose \frac{n}2$.

\startformula
n \choose \frac{n}2
\stopformula

\CONTEXT\ \contextmark\ \contextversion\ with \texenginename\

\stoptext

the parentheses of the binomial in the text or too short. I guess this
is because the parentheses are not scaled when inlined and that this is
also a TeX limitation and therefore expected?

these were great news indeed! Thank you for your effort.

 The release of gnuplot 4.4.4 was initially planned for around October,
 which means that it should probably be out sometime soon.

Unfortunately it looks like the ConTeXt terminal was not included in
version 4.4.4 released on November 14th [1] and is just planned for
version 4.5 [2]. Can you confirm this?

 No, I get subscripts for all listed fonts but it’s possible we use different 
 versions of the them.

Even more trivial. I do not have Cambria installed and Libertine is also
not found although I have the Debian package (fonts-linuxlibertine,
5.1.3-1) installed. I guess I need to update the cache somehow.


Thanks,

Paul

  As a workaround `A^{\prime}` can be used.
 
 Forget about superscripting prime .. that's a traditional tex thing as 
 in cm/lm fonts the prime is so big that it has to be (super)scripted to 
 look okay.
 
 The prime in unicode is a normal one so that's what we now support, also 
 for the lm fonts. Just compare:
 
 \startformula
  A\prime
  \hbox spread 1em{\hss or\hss}
  A^{\prime}
  \hbox spread 1em{\hss or\hss}
  A'
 \stopformula
 
 Keep in mind that most users expect ' to be a prime.

Interesting. Thank you for the clarification. I will use A' from now on
I guess.


Thanks,

Paul

[NTG-context] \in: incorrect space in example in reference

2011-11-16 Thread Paul Menzel
Dear ConTeXt folks,


in the example for `\in` in the reference [1] there is a space after the
»(«.

\placeformula[eq:pythagoras]
\startformula
  a^2+b^2=c^2
\stopformula

This is explained in \in{Equation (}{)}[eq:pythagoras].

Normally this space is useful since the suffix is something like Table
or Figure.

Can `\in` be used with brackets or does another command have to be
defined/used for that?

 Use \definereferenceformat to create your own command.

to correct this in the reference do I just edit the Wiki article or is
the reference automatically created?

[NTG-context] url: Add macros to the ConTeXt core

2011-11-13 Thread Paul Menzel
Dear ConTeXt folks,


looking into typesetting URLs I find typesetting URLs quite cumbersome.

Maybe I have not used that feature that often so I am not seeing the
advantage to first define a URL somewhere and give it a name

\useURL[aurl]   [http://xkcd.com/149/] [] [I prefer hot
dogs.]

and then later use it.

\url[aurl]

The proposed macros(?) in the section »Tipps and Tricks« [2]

\def\href#1#2{\useURL[#2][{#2}][][{#1}]\goto{\url[#2]}[url(#1)]}
\def\ahref#1{\color[linkcolor]{\ttx \href{#1}{#1}}}
\def\fullahref#1{\color[linkcolor]{\ttx \href{#1}{http://#1}}}
\def\mailto#1{\useURL[#1][mailto:#1][][#1]\from[{#1}]}
\def\MailTo#1#2{\useURL[#1][mailto:#1][][#2]\from[{#1}]}

seem quite useful. Could they be added to the ConTeXt core(?)?

[NTG-context] idea: Module to automatically extract and insert information from Wikipedia

2011-11-12 Thread Paul Menzel
Dear ConTeXt folks,


just now I thought of the following and I am wondering if there exists
already a solution.

Writing a text which includes people I want to add information about
these peoples as footnotes. The first sentence in a Wikipedia article is
most of the time good enough for that.

A macro `\infofromwikipedia{Donald Knuth}` would be nice which gets the
first sentence of the article and puts an item into the bibliography.

There is even an API to access articles [2]. Besides coding that up I
see the following problems.

1. The output [3] needs to be converted to ConTeXt.
2. An Internet connection would be necessary. But that is just a note
and not a problem.


Thanks,

Paul

Thanks! I have not understood the repository layout yet. For example
will the branches be merged to the master branch eventually or are those

[NTG-context] MetaFun manual: Incorrect label of ordinate axis on page 382, section 9.3 drawing functions (was: Confusion with `function()` and `xyscaled`)

the labeling of the vertical axis (y-coordinate) is not incorrect.

The maximum value is 10 and therefore it should probably be corrected as
follows.

- draw hlingrid(0, 20, 1, 20cm, 10cm) ;
+ draw hlingrid(0, 20, 2, 20cm, 10cm) ;

- draw hlintext.lft(0, 20, 5, 20cm, @3e) ;
+ draw hlintext.lft(0, 10, 5, 20cm, @3e) ;

Furthermore on the bottom labels seem to be incorrect in the figure, it
goes from 1 to 0, but this seems to be a bug in the used ConTeXt
version, since I do not have that problem when compiling(?) that example
locally.

Please find the corrected example attached.

  I agree, this is confusing on the first sight. But scaling is not meant
  as 'scaling to' a dimension. In fact is is just a simple multiplication.
  The reason why it seems to work this way with
  'fullsquare' and such predefined paths is, that they have a 'neutral'
  size/scale (bounding box size of filled path is (1pt,1pt)).
  
  So how can I find out what the dimension of the path of a function is?
  Not scaling it, it also looked pretty small, so I am guessing (1pt,1pt).
 
 I guess in this case its size is (10,log(10)) + pen size when drawn.

That was it kind of. Probably the most of my confusion resulting from
the use of the inverse function.

So all in all the width is 1 – the x-coordinates seem to be scaled to
the width of 1 – and the height is 10, as ten is the highest value.
Therefore the width has to be multiplied with 10cm to get it to 10cm and
since the height it 10 already multiplying it with 2cm gets it to 20cm.

  Multiplying such a path with (x,y) gives an object with size (1*x,1*y).
  In general: if the bounding box of an object has the size (a,b) and you
  scale it with (x,y), the resulting object has a size of (ax,by). That's
  all the magic.
  
  but if you use numbers with a unit than it should not be multiplied but
  expanded to that value, should not it? Otherwise I am unsure how
  multiplication works with a unit.

 1pt is the base unit in MP (used if no dimension is given; probably
 stored as 65536sp (scaled point) units).

In the manual I only found bp for »big point«, which equal PostScript
points equaling 1/72 of an inch.

 Now if you use pure numerics for scale, such as 'xscaled 2', this is
 interpreted as '2pt' (or 2*65536sp). If you use any dimension, it is
 also converted into scaled points. All the same for MP.
 
 If I'm right this should all be the same (untested)
 
 xscaled 2
 xscaled 2pt

This gives the same result.

 xscaled (2*65536sp)

I could not test the above because the numbers got too big and MetaPost
complained.

 1 = 1pt = 65536sp

Paul

 I am confused how the resulting function is scaled correctly. The
 resulting dimensions seem to be 10cm and 18 cm. So I guess the 2 cm mean
 to shift it up some how.
 
 Could someone please explain to me how `xyscaled` works in this case
 please. I though `xyscaled (αcm, ζcm)` would set the object/path to a
 width of α cm and a height of ζ cm.

Looking up the definition of the macro `xyscaled` it is indeed just a
short version of `xscaled αcm yscaled ζcm`.

$ more mp-tool.mp
[…]
%D More robust:

% let  normalscaled =  scaled ;
% let normalxscaled = xscaled ;
% let normalyscaled = yscaled ;
%
% def  scaled expr s =  normalscaled (s) enddef ;
% def xscaled expr s = normalxscaled (s) enddef ;
% def yscaled expr s = normalyscaled (s) enddef ;

%D Shorter

primarydef p xyscaled q =
  begingroup ; save qq ; pair qq ; qq = paired(q) ;
( p
  if xpart qq0 : xscaled (xpart qq) fi
  if ypart qq0 : yscaled (ypart qq) fi )
  endgroup
enddef ;
[…]

I am still confused though what happens in the above example scaling the
path of the function.

Trying

\starttext
\startMPcode
  draw fullsquare xscaled 10cm yscaled 2cm;
\stopMPcode
\stoptext

the resulting rectangle has the dimensions of 10 cm width and 2 cm
height but the path of the function above does not.

Re: [NTG-context] MetaPost: Confusion with `function()` and `xyscaled`

2011-10-21 Thread Paul Menzel
Dear Peter,


thank you for your answer.

Am Freitag, den 21.10.2011, 17:02 +0200 schrieb Peter Rolf:

 I agree, this is confusing on the first sight. But scaling is not meant
 as 'scaling to' a dimension. In fact is is just a simple multiplication.
 The reason why it seems to work this way with
 'fullsquare' and such predefined paths is, that they have a 'neutral'
 size/scale (bounding box size of filled path is (1pt,1pt)).

So how can I find out what the dimension of the path of a function is?
Not scaling it, it also looked pretty small, so I am guessing (1pt,1pt).

 Multiplying such a path with (x,y) gives an object with size (1*x,1*y).
 In general: if the bounding box of an object has the size (a,b) and you
 scale it with (x,y), the resulting object has a size of (ax,by). That's
 all the magic.

but if you use numbers with a unit than it should not be multiplied but
expanded to that value, should not it? Otherwise I am unsure how
multiplication works with a unit.

 I must admit that this wasn't clear to me before you came up with your
 question. So thanks for that. :-)

Thank you for your answer. As written above it is still not entirely
clear to me. I hope you can remedy my last confusion.


Thanks a lot,

Paul

[NTG-context] MetaFun: Confusion with `function()` and `xyscaled`

2011-10-20 Thread Paul Menzel
Dear ConTeXt/MetaFun folks,


looking at the example for grid and functions in the MetaFun manual [1]
section 9.3

drawoptions(withpen pencircle scaled .25pt withcolor .5white) ;
draw hlingrid(0, 20, .2, 20cm, 10cm) ;
draw vloggrid(0, 10, .5, 10cm, 20cm) ;
drawoptions(withpen pencircle scaled .50pt) ;
draw hlingrid(0, 20, 1, 20cm, 10cm) ;
draw vloggrid(0, 10, 1, 10cm, 20cm) ;

fmt_pictures := false ; % use TeX as formatting engine
textextoffset := ExHeight ; % a variable set by ConTeXt
draw hlintext.lft(0, 20, 5, 20cm, @3e) ;
draw vlogtext.bot(0, 10, 9, 10cm, @3e) ;

draw
function(1,log(x),x,1,10,1) xyscaled (10cm,2cm)
withpen pencircle scaled 5mm withcolor transparent(1,.5,yellow) ;

I am confused how the resulting function is scaled correctly. The
resulting dimensions seem to be 10cm and 18 cm. So I guess the 2 cm mean
to shift it up some how.

Could someone please explain to me how `xyscaled` works in this case
please. I though `xyscaled (αcm, ζcm)` would set the object/path to a
width of α cm and a height of ζ cm.


Thanks,

Paul

great to hear that. Just to clarify, with »now« you mean MetaPost v2, do
not you? Taco, I hope you get there without a lot of problems showing
up. If you need testers a good option would be to integrate that into
ConTeXt Standalone as an option.

 The graph package is pretty clever, and I am working on proposals on
 how to extend/rewrite this taking advantage of the new metapost
 handling of large and small numbers.

Perfect!

 To plot a function, you can create a path, as in
 path p ; p := 
   for i=0 upto 1000:
   hide (x := i/1000 ;) 
   if (i0) -- fi (x,exp(x))
   endfor ;
 gplot p ;

What module do I need for `gplot`?

Looking at the MetaFun manual [8] I found out MetaFun even provides a
macro `function` which probably does exactly what you do above with the
for loop.

draw function(2,x,x**(-0.5),1,10,1) xyscaled (2cm,2cm)
withpen pencircle scaled 5mm withcolor
transparent(1,.5,yellow) ;

 One proposal will be to make this even easier with new macros.

Another perfect!

One thing coming to my mind though that hopefully the wheel is not
reimplemented. I guess Gnuplot can do a lot already, but on the other
probably not as neat as Metapost when we want to color certain areas.


Thanks,

Paul

 No, 1.750. The version 2 is not quite ready yet, but the version 1.750

Thank you for the clarification/correction.

 It will become part of distribution as soon as it gets out, but Taco
 was busy enough organizing conference and dozens of other things. Just
 give him some time. I bet that he also wants to update documentation,
 do final bugfixing etc. instead of just releasing a random snapshot.

Of course the user would have to make a conscious decision by enabling
this “beta” release. If people could test this and with the right
announcement I hope that some people would step up to test and
contribute by submitting bug reports or writing documentation.

  One thing coming to my mind though that hopefully the wheel is not
  reimplemented. I guess Gnuplot can do a lot already, but on the other
  probably not as neat as Metapost when we want to color certain areas.
 
 Can you please specify your question more precisely?

I meant coloring part of the area below a graph. For example if you look
at the graphic for Riemann sums on page 51 of the document »Learning
MetaPost by Doing« [6].

 Gnuplot terminal uses metapost output. Gnuplot has some support for
 transparency, even though I'm not exactly sure if one can specify
 transparent colors for lines, only for fills. But you can always
 simply redefine line type colors to be transparent.
 
 Gnuplot brings all kinds of other problems like dependency on external
 tool. If you have enough time to create nice plots in metapost, it is
 better to avoid external dependency as a general rule. But if you have
 more questions about it, feel free to ask. I might be able to help
 you.

Well my only question would be, why should someone use Gnuplot then? Is
it only for people already knowing Gnuplot? Or also because it is a
little less work to define the coordinate system and legends?

Otherwise MetaPost seems to include all functionality Gnuplot offers and
seems to offer more possibilities, does not it?

 The ConTeXt terminal was almost included until developers
 realized that they wanted me to throw away some code for handling
 units and replace that code with something buggy (like size 10cm,10
 - (10cm,10cm); size 10,10cm - (0.35cm,10cm) or (25.40cm,10.00cm)
 depending on weather). Now I need to either rewrite part of my code or
 rewrite part of core code or convince them why keeping the old code.

I remember a thread about that [9].


Thanks,

Paul

[NTG-context] Plotting a graph of a function f, like f(x) = e^x, with MetaPost

2011-10-11 Thread Paul Menzel
Dear ConTeXt folks,


I finally chose MetaPost/MetaFun [1] because of the native integration
with ConTeXt and hopefully easy font handling. I want to use that
throughout my document.

Of course I hit the first problem. Wanting to draw a “simple” function f
like f(x) = e^x, seems hard to accomplish. I guess I should stress that
MetaPost does not have a high accuracy so it might not be the best
solution [5].

There seem to be quite a lot of solutions (mostly macros) on the Web for
this problem so I am wondering if one of them is integrated in MetaFun.

Here are some of my findings.

1. Reading about the graph package by John D. Hobby [2] and which is
also included in ConTeXt [3]. Especially I liked the automatic
coordinate systems. The package seems to only be able to plot graphs
with data points saved in files. So one solution would be to manually
create data files with data points of the relevant function.

2. There is an example in the Drexel Physics Wiki [4].

3. Anthony Phan has also created some macros in his `mps` [5 (currently
not accessible)].

4. André Heck uses the macro packages `courbes` and `grille` from
Jean-Michel Sarlat to show some nice examples in his tutorial »Learning
Metapost by Doing« [6].


So what do you suggest?


Thanks,

Paul

 with ConTeXt and hopefully easy font handling. I want to use that
 throughout my document.
 
 Of course I hit the first problem. Wanting to draw a “simple” function f
 like f(x) = e^x, seems hard to accomplish. I guess I should stress that
 MetaPost does not have a high accuracy so it might not be the best
 solution [5].
 
 There seem to be quite a lot of solutions (mostly macros) on the Web for
 this problem so I am wondering if one of them is integrated in MetaFun.
 
 Here are some of my findings.

I just want to add that there seems to be work going on in ConTeXt to
solve these issues as the talk at this years ConTeXt User Meeting of
Alan Braslau suggests [7].

 1. Reading about the graph package by John D. Hobby [2] and which is
 also included in ConTeXt [3]. Especially I liked the automatic
 coordinate systems. The package seems to only be able to plot graphs
 with data points saved in files. So one solution would be to manually
 create data files with data points of the relevant function.
 
 2. There is an example in the Drexel Physics Wiki [4].
 
 3. Anthony Phan has also created some macros in his `mps` [5 (currently
 not accessible)].
 
 4. André Heck uses the macro packages `courbes` and `grille` from
 Jean-Michel Sarlat to show some nice examples in his tutorial »Learning
 Metapost by Doing« [6].
 
 
 So what do you suggest?


Thanks,

Paul

Re: [NTG-context] math signs in itemize

Is there a font in Standalone which can be used to demonstrate the
behavior?

 \starttext
 1/40 {\setff{frac}1/40} \m{\frac{1}{40}}

With `{\setff{frac}1/40}` the output is like ¼0. Using `{40}` also does
not help.

 \stoptext


Thanks,

[NTG-context] Fifth International ConTeXt User Meeting from September 19th until 24th

2011-09-22 Thread Paul Menzel
Dear ConTeXt folks,


for those wondering why the traffic on this list is quite low during the
last few days, I guess the reason is most of the developers and active
supporters are attending the fifth International ConTeXt User Meeting
[1].

I wish a great time to everybody attending the meeting.


Thanks,

Paul

Somehow the README on CTAN [2] is not converted to HTML. So the links which 
would be created by Markdown cannot be used usable.

 Thanks for both patches, it'd be better to open issues in github

I have no account at GitHub.

 or send me mails directly, to not bother the list with offtopic mails.

I will mark them as off topic next time or send it to you directly.

Just one question. Can you give me the reason why you did not use `git
am`?


Thanks,

Paul
