Thanks for the modified documentation of the graph macros. It has been a
great help. Is it in the lmtx distribution somewhere?

I read about the upcoming luagraph in mag-1104-mkiv.pdf (This Way
11/11/2019) and have also played a bit with LuaMetaFun and Aditya's blog
post. Looking forward to that development, thank you!

Thank you again, but the "0.0" remains unchanged. The only way I've been
able to succeed is with a for loop to label explicitly. See mwe below for
things I've attempted. The last two for lines seems to be what it takes
(with the other Auto lines commented out of course.)

Thanks Alan. I see those lines in the module listing, but could you provide
some guidance on usage? Can the (re)formatting be done from my input file,
or do I need to modify mp-grap.mpiv, or some other way?

(Apologies for double-dipping, but usage direction for the least-squares
fit extension in m-graph would be a gift.)

Re: [NTG-context] vertical alignment of images in Natural Table

Martin Althoff wrote:

Hello, I am trying to vertically align images within a

The result should be 4 cards on an A4 page with a simple maths

after the text. Exercise text and image size vary somewhat, so a

I have tried \vfill, but it seems to have no effect in a Natural

As basic layout I am using a Natural Table (4 x 4 cells per page, 12

most welcome.

Thank you Wolfgang. I had to change .5\localhsize to .5\textwidth for it to 
work here (and scale down the cow to make it fit in the barn.)

I am looking into combinations to center the graphic in the second x box, and 
make a \setupcombination[mycombination] similar to \defineparagraph[Mypar] to 
reduce typing.

\tbox is new to me. Is that a ConTeXt macro of TEX \vtop{\hbox}?

Thank you for this insight Alan! Two results immediately helpful are:
1) data can be put at the top of the .tex file
2) autogrids can be rendered and then drawn over

The following may not be the best way, but it works to read data from the top 
of the .tex file and then plot on the autogrid.

% 1 0.5 2.5
% 2 1 3.5

\usemodule[graph]
\startMPpage[instance=graph,offset=2mm]
  draw begingraph(3cm,5cm);
  numeric a[];
gdata("read1.tex", v,
  setrange(0,0,3,4);
);
closefrom "read1.tex";

autogrid(,grid.lft) withcolor .7white;

gdata("read1.tex",v,
for j = 1 upto 3:
a[j] := scantokens v[j];
  endfor;
  path b;
  augment.b(a1,a2);
  augment.b(a1,a3);
  setrange(0,0,3,4);

Thank you Alan. setrange is the key I had not tried and I will be more careful

Thank you Hans. Do you mean numeric a[n]? It was not explicitly declared; I did

[NTG-context] m-graph read data and plot

[John Kitzmiller]

Given a file, data.d, containing 1 4 7

  draw begingraph(5cm,5cm);

Hello Fabrice,

labeloffset does not work with Hans’ code above using ‘draw thetextext’ for 
labels. It works with the label macro:

\startMPpage[offset=2mm]
 path p, q, r ; pair z ;
 p := unitsquare scaled 4cm ;
 z := point 3.6 of p ;
 q := z--urcorner p ;
 r := q -- reverse bottomboundary p -- cycle ;
 draw p ;
 draw q ;
 draw r numberstriped (.25,10,5) withcolor blue ;
 labeloffset := 2mm ;
 label.llft("B", llcorner p) ;

There is also anglestriped in mp-tool with some examples. The second argument 
changes the angle.

\startMPpage[offset=2mm]
  path p, q ;
  p := unitsquare scaled 4cm ;
  z1 = point 3.6 of p ;
  q := subpath (0,2) of p -- z1 -- cycle;
  q := q shifted(-4cm,-4cm);
  draw q anglestriped(1,180,6) withcolor blue;
  draw p ; 
\stopMPpage

(I have not yet found why the striped path q goes out of position. Looking at 
mp-tool may help.)

Try the mpost variable lableoffset := ? to adjust.

It is a MetaFun macro in mp-tool, afaik.

The idea of filling a path is sometimes clipping to a path. Here is a way to do 
your task with (almost) only MetaPost:

\startMPpage[offset=2mm]
 path p, q ;
 p := unitsquare scaled 4cm ;
 z1 = point 3.6 of p ;
 q := z1 -- urcorner p -- lrcorner p -- llcorner p -- cycle;
 for i = 8 step -.5 until 0:
   draw (i,0)*cm -- (i-4,4)*cm withpen pencircle scaled 2pt withcolor blue;
 endfor;
 clip currentpicture to q;
 draw p ; draw q ;
 label.llft("B", llcorner p) ;
 label.lrt ("C", lrcorner p) ;
 label.ulft("A", ulcorner p) ;
 label.urt ("D", urcorner p) ;
 label.lft ("M", z1) ;
\stopMPpage

…just in case it helps to clarify.

[NTG-context] 2UP Arranging

[John Kitzmiller]

Using 2UP the rightmargin on odd (recto) pages becomes the leftmargin on even 
(verso) pages.

Is there an option for 2UP doublesided to be printed and folded where the 
rightmargin is always on the righthand side of each ‘page’ from the reader’s 
viewpoint? Or another layout scheme to get the same result?

This mwe shows 2UP default:

\definepapersize[booklet][width=140mm,height=216mm]
\setuppapersize[booklet][letter,landscape]
\setuppagenumbering[alternative=doublesided]
\setuparranging[2UP,doublesided]

\setuplayout[
  width=92mm,
  leftedge=0mm,  
  leftmargin=0mm,
  backspace=15mm,
  rightmargindistance=3mm,
  rightmargin=25mm,
  ]

\showframe

\starttext
\dorecurse{4}{\input ward \page}
\stoptext

And this gives an image of the desired layout:

\definepapersize[booklet][width=140mm,height=216mm]
\setuppapersize[booklet][letter,landscape]
\setuppagenumbering[alternative=doublesided]
\setuparranging[2UP,doublesided]

\setuplayout[
  width=92mm,
  leftedge=0mm,  
  leftmargin=0mm,
  backspace=15mm,
  rightmargindistance=3mm,
  rightmargin=25mm,
  ]

\definelayout[evenside][
  width=92mm,
  leftmargindistance=3mm,
  leftmargin=25mm,
  backspace=43mm,
  rigthedge=0mm,
  rightmargin=0mm,

\showframe

\starttext
\input ward \page
\setuplayout[evenside] \input ward \page
\setuplayout[reset] \input ward \page
\setuplayout[evenside] \input ward 
\stoptext

I would like to avoid the manual switching if possible. Thanks!

Thank you Wolfgang.

Follow-up question: how to have a right margin appear on the right side of 
every booklet page?

The layouts I have tried with the following mwe put the right margin on the cut 
side of the paper, but that “reverses” the margin side from the reader’s view 
when printed and folded.


\definepapersize[booklet][width=140mm,height=216mm]
\setuppapersize[booklet][letter,landscape]
\setuppagenumbering[alternative=doublesided]
\setuparranging[2UP,doublesided]

\setuplayout[
  width=90mm,
  leftedge=0mm,  
  leftmargin=0mm,
  backspace=15mm,
  rightmargindistaince=3mm,
  rightmargin=25mm,

[NTG-context] letter booklet

[John Kitzmiller]

Desired outcome: a multipage booklet on letter size paper with margins lined up 
when duplex printed and folded.

Using imposition with [letter][letter,landscape] did not work, so to start I 
used:

\definepapersize[booklet][width=140mm,height=216mm]
\setuppapersize[booklet][letter,landscape]
\setuparranging[2UP,doublesided]
\setuplayout[width=115mm,
  leftedge=0mm,  
  leftmargin=0mm,
  backspace=15mm,
  rightmargin=0mm,
  rigthedge=0mm]  
\showframe
\starttext
\dorecurse{8}{\input Ward \page}
\stoptext

but the inside and outside margins do not line up. Where is the elegant path?

Thanks, John

the external file— a marker and test structure?

Thanks again,

John

Many thanks to you Akira.

Reading the file into lua tables is good sense, and thank you for the string 
manipulations to pass to metafun().

From your teaching I changed this assignment:

> t1 = tostring(x[1])
> t2 = tostring(y[1])
> s = s.."("..t1.."cm,"..t2.."cm)"
> s = s.." withpen pencircle scaled 1bp;"

to: s = s.."cycle withpen pencircle scaled 1bp;”

to close the polygon.

With respect,

John

[NTG-context] plot data from file: cld

[John Kitzmiller]

I seek how to use context-lua to draw a path from ‘points’ in an external file. 

Below is one way to plot points from an external file, call the file DATA with 
contents:

1 3
-2 2
-3 -1
3 -2

\starttext
\startluacode
local metafun = context.metafun
metafun.start()

io.input(“DATA")
while true do
  local x, y = io.read("*n", "*n")
  if not x then break end
  metafun("filldraw fullcircle scaled 2mm shifted(%dcm,%dcm);",x,y)
end

metafun.stop()
\stopluacode
\stoptext


How to make this a polygon?

I know other ways to read and manipulate DATA with Lua—it is the drawing part 
where I most look for help.

Thanks,
John

Here is setup magic from Hans and Aditya from August 2013:


\usetypescriptfile[euler]

\definetypeface[myfamily][ss][sans] [dejavu][default]

\setupbodyfont[myfamily]
\appendtoks \rm \to \everymathematics
\setupmathematics

One can change the families, e.g. schola for pagella, etc., but I think the  
last [pagellaovereuler] and the rest has to stay.

Yes it helped Peter, thank you. Interesting moves with the mpost bounding box.

I thought I might need more flexibility—overlays—but it has turned out that 
single mp graphic with labels for the commentary will work for the task.

[NTG-context] Lua to Context Table

[John Kitzmiller]

Here is Lua code that prints the first nine fibonacci numbers:

local function fib(n)
  f={1,1}
  for i=3,9 do
f[i]=f[i-1]+f[i-2]
  end
  return(f[n])
end
for n=1,9 do print(fib(n)) end

Here is Context+Lua that prints 3 x 3 table of the first nine natural numbers:

\starttext
\setupTABLE[each][each][frame=off,align=left,width=4em,height=2em]
\startluacode
context.bTABLE()
for j = 0, 2 do
  context.bTR()
for k = 1, 3 do
  context.bTD()
context(3*j+k)
  context.eTD()
end
  context.eTR()
end
context.eTABLE()
\stopluacode
\stoptext

How can these be combined to print a 3 x 3 table of the first nine fibonacci 
numbers?

I have tried a couple of ways to iterate over the lua table f in the most 
indented line of context, looked at what pertinent threads I could find, the 
Wiki entries, CLD, and tried Aditya's method from Stack Exchange; I am missing 
something.

I installed Ubuntu on the chromebook using crouton 
(http://lifehacker.com/how-to-install-linux-on-a-chromebook-and-unlock-its-ful-509039343)
 and then apt-get context which gave a texlive version for armhf; also got vim 
and evince. From terminal under Ubuntu, which runs on top of ChromeOS, context 
foo.tex compiled a Hello World and a \startMPpage figure. That much worked.

This made me think the link for armhf-linux above might work without Ubuntu, 
but I am not skilled enough to use the trunk/Master--I got a text sym-link and 
a 7.3mb luatex file that I can not yet make executable (command not found.)

The texlive/acquire-netinstall results in 'Permission denied' even with sudo on 
the chromebook.

I have not yet tried Martin's approach with the .deb files but wanted to report 
back and thank you both for your suggestions.

John

Thank you Martin. I was not clear. I can run Debian and other *nix flavors on 
the chromebook by various methods and then have ConTeXt, but I would rather not 
'dual boot.'

What I am after is to have ConTeXt run 'natively,' if that is the right 
word/concept, on a chromebook core platform. From the chromebook shell I know I 
can run vim to edit files but I would like to compile them. (Viewing will be 
the next chapter!)

\setupitemgroup [itemize] [n,style=bold,right=\ansblank]

Desired output:

2. Second
a. Related problem2a. 
b. Related question   2b. 

3. Third  3. _


My attempts have been to define a new "blank" and use [conversion=Character]

I too would like to use Neo Euler for math but need some of the missing

[NTG-context] bar graphs, m-graph, sarith

[John Kitzmiller]

When trying to make a bar graph with m-graph.mkiv and sarith, the command Ssub 
(string subtract) seems to Sadd instead. An mwe of a bar graph:

 (data1 is a separate file containing
  01 02
  02 03)

\usemodule[m-graph]
\startMPpage[instance=graph]
input sarith;
draw begingraph(5cm,5cm);
 gdata("data1", v,
  path p;
  augment.p(v1,0);
  augment.p(v1,v2)
  augment.p(v1 Sadd "0.4",v2);
  augment.p(v1 Sadd "0.4",0);
  gfill p--cycle withcolor .8white;
  gdraw p--cycle;
  );
endgraph;
\stopMPpage

...which gives bars of width 0.4 starting at abscissa 1 and 2 as expected. To 
increase the width of the bars to 0.8 and have them centered over 1 and 2, I 
expect to Ssub from the first two augments:

\usemodule[m-graph]
\startMPpage[instance=graph]
input sarith;
draw begingraph(5cm,5cm);
 gdata("data1", v,
  path p;
  augment.p(v1 Ssub "0.4",0);
  augment.p(v1 Ssub "0.4",v2);
  augment.p(v1 Sadd "0.4",v2);
  augment.p(v1 Sadd "0.4",0);
  gfill p--cycle withcolor .8white;
  gdraw p--cycle;
  );
endgraph;
\stopMPpage

However, the Ssub adds instead and gives a line at 1.4 and 2.4.

Compiling the above with mpost or mptopdf gives the desired result(s), but I am 
curious if this can be resolved so such bar graphs could be made within 
ConTeXT/METAFUN.

Thanks! John

Thank you Mojca,

Your idea did help for minimal examples. I get conflicts with more elaborate 
files (even the dreaded 'cannot make .mpx file') sometimes using either 
suggestions so...

retraining my fingers to put MP code in \startMPpage is the direction I will 
take because it gives the best looking forward result for me.

Thank you Hans. It works (no surprise) but now I will have to script it to save

[NTG-context] mptopdf in minimals

[John Kitzmiller]

Is there something extra needed to use mptopdf with only context minimal?

Experimenting with having just context standalone on mac osx:





















 Compiling with just mpost 
or using a context \startMPcode wrapper works, e.g.:

beginfig(1);
draw origin--(100,100);
endfig;
end

works with command line mpost % 

This is MetaPost, version 1.801 (kpathsea version 6.1.1dev)
(mpost.mp (/users/johnkitzmiller/context/tex/texmf/metapost/base/plain.mp
Preloading the plain mem file, version 1.004) ) (./mwe.mp [1] )
1 output file written: mwe.1
Transcript written on mwe.log.

and...

\starttext
\startMPcode
draw origin--(100,100);
\stopMPcode
\stoptext

works with command context %

But using mptopdf on the first snippet complains:

MPtoPDF 1.4.1 : running 'mpost --mem=mpost  mwe.mp'
This is MetaPost, version 1.801 (kpathsea version 6.1.1dev)

(Note: I do not have TeX Live 2013 installed. The message from line 7 gave me

[NTG-context] arc notation Lucida

[John Kitzmiller]

My primary plea for help is how to make an arc symbol over 3 letters in ConTEXt 
with lucidaot as body font.

In pdfLaTeX I could use package fourier to get such an extensible symbol where 
\widearc was preferable to \widehat.

Hans' new "about" regarding extensible glyphs is suggestive, but because I am 
kind of a dope, leads me to my secondary call for help:

How can I directly enter the 'code' for a LucidaBrightOT character from the 
tables at TUG:

http://www.tug.org/store/lucida/otmath-blocks.pdf

and see the result? Or find the name to use in a math $ \symbolname $ 
environment?

Thanks, Kitz

Thanks Marco, it is a start and would have taken me a long time to get
there, however, the rule number is not inside the margin (the
location=right I think doesn't quite do it) and the rule number is
bold? I will pursue the direction you set me.  --John

[NTG-context] enumerate fillinlne

[John Kitzmiller]

Any hints on enumerating fillinlines? Below describes the request (I
hope this fomats okay on forum) the answer lines align with the top
line of the question and are in a margin column:

1. Here is a question.  1. __

2. Here is another question. If it wraps2. __
   around the text should be in a block and
   the fillinline should be aligned with the
   first line of the question. Diagrams can
   also be part of the questions.

I accomplish this in pdfLaTeX by defining command:

\newcommand{\ansblank}{\leavevmode\marginpar{\labelenumi\hrulefill\raggedright\par}}

So, in enumerate environment \item\ansblank does the the trick. My
inexperienced attempts with ConTeXt make a terrible hash of it.
Thanks.

Re: [NTG-context] SciTE configuration to use mkiv instead of mkii

It looks like you need to point Scite to

[NTG-context] Scite Lexers

[John Kitzmiller]

This may not belong here but perhaps someone would be willing to confer
with me off-list?

After Scite re-install with new MkIV instructions I can not find where to
change background color. (I was able to change it before under ebswift
installation although syntax highlighting for *tex did not work--such a
deal!)

The only lead I have so far is, commenting out "import lexers/lpeg" in
SciteGlobal.properties takes away all highlighting for all languages.

I know there is a warning about lexer interaction from November 2011, but I
have not had any other problems (except Purge All does not work) with Scite
3.02, lpeg lexers 3.02-1, and ConTeXt  ver: 2011.12.20 22:24 MKIV.

Thanks, John

Hello Gerard.

Moving the [offset=*] down to \startMPpage and eliminating the \setup
MPpage worked here. (I also scaled it up so I could see it on my viewer.)

\startuseMPgraphic{test}

fill fullsquare rotated 45 scaled 20;

\stopuseMPgraphic

 \starttext

\startMPpage[offset=5pt]

\includeMPgraphic{test}

\stopMPpage

\stoptext


This may be a feature.

You need to have C:\context\tex\texmf-mswin\bin in front of MikTeX's
bin, else the command "context" will use LuaTeX from MikTeX and that
one won't find ConTeXt scripts.

However, you might stumble into some problems with LaTeX then, but it
might be possible to remove pdfTeX (during installation of ConTeXt you
can say --engines=luatex) and then it will be unlikely that you will
want to use the same binary with ConTeXt and LaTeX (I have no idea how
kpathsea would work in such a scenario).

Mojca

end of quote ---

Good thinking Mojca! Moving C:\context up in PATH has done the trick from
the command line. Now I will fuss getting editor to work.

I compiled a few of my standard docs through MiKTeX pdflatex and mpost docs
with no conflict so far. Thank you so much for the suggestion and thanks to
luigi and Hans for their help too.

Then I will read and play with wonderful ConTeXt manuals and generate a
million more questions ;)

[NTG-context] Lua script not registered

[John Kitzmiller]

Replying to the list in this manner--having to retype the subject--is
unusual to me, and I hope it does not create problems for the list. Please
help me on how to reply within the mail archive to make more efficient.
Many thanks to those who have replied on the topic!

Thank you, Aditya--

I had run C:\context\tex\setuptex.bat and then tried

C:\context>context firstfile.tex

which worked (now down to 3+ secs from 11+ at first run--file = \starttext
Hello World \stoptext)

I think I can get this setuptex.bat automated for random context runs but,

for some reason(s) C:>context somefile.tex will not work globally on my
personal computer (Lenovo x100e) over which I have admin control (maybe I
am not a good admin?) and I have added C:\context\tex\texmf-mswin\bin to my
PATH

I still get "Lua script not registered" complaint when I try to compile
outside of C:\context directory

I suppose I could live with keeping all binaries and docs in C:\context,
but that is not so inviting compared to being able to pdfLaTeX a doc over
Dropbox via MikTeX for example.

[NTG-context] Lua script not registered

[John Kitzmiller]

I hope this does not open another thread with the same name, but I did not
find a way to respond directly within the archive--something else I am
missing or will ntg find the reference? Here it goes...

Thank you for response luigi. The story:

OS = Windows7 professional
I also have MikTeX installed which I use routinely for pdfLaTeX and
METAPOST from TeXworks

download 
context-setup-mswin.zip
from
the wiki
unzip to  C:\context
run from shell  C:\context>first-setup.bat --modules=all
add to PATH  C:\context\tex\texmf-mswin\bin\
run from shell  C:\context>first-setup.bat --keep

Then create tex file \starttext Hello world \stopptext  in different
location.

Navigate shell to that location and  >context firstfile.tex

Result is  message
context: The Lua script is not registered.
context: Data: context

Aha! I tried moving firstfile.tex into C:\context and then run and it
works, but takes 11.62 seconds--not so good.

However, I still get Lua script not registered when I try to run from other
file locations, which makes me think it is PATH problem that I will
continue to chase but if anything looks obvious please help.
