[NTG-context] Re: Gray gradient with Metapost
Hi Fabrice,
You could define you own shades of gray (I believe there are at least
50) by adjusting the rgb values as I've shown below.
definecolor [ name = "verylightgray", r = 0.995, g = 0.995, b = 0.995 ] ;
definecolor [ name = "lightergray", r = 0.55, g = 0.55, b = 0.55 ] ;
draw lmt_shade [
path = (z0--z4--z5--z1--cycle),
direction = "left",
alternative = "linear",
colors = {"lightergray", "verylightgray"},
] xshifted 5cm;
I added it to your code after the lines:
draw z0--z4--z3--cycle;
draw z1--z5--z2--cycle;
draw rectangle;
Hope this helps.
Best Wishes
Keith

[NTG-context] Re: your opinion about list structures
Hi Hraban Here are my thoughts on your ConTeXt Book. [TOC] Definitely only show Chapters and Appendices. A list of sections could go under the Chapter Title, it would more useful there. I don't think there is also a need include sub-sections, (if you have them) it could make the list inordinately long. [Registers] My own preference would be a command and a topic index if only for convenience sake. [Glossary] I don't think an index of abbreviations is necessary if they are already in the index. [Other Lists] I don't think a list of colours is necessary, you could just point them to the wiki. Just my thoughts, and I look forward to read the English version of your book. (smiling) Best Wishes Keith McKay p.s. It's been so long since I worked with technical books that I would have to blow the dust off them. On 10/08/2023 14:21, Henning Hraban Ramm wrote: Hi, this is about my ConTeXt book again… [ToC] At the moment, my table of contents has chapters and sections and is 8 pages long. I would probably hardly use it. Maybe it would be better to show only chapters (29 content + 12 appendix = 2 pages) and include a list of sections after the chapter title (or not at all). [Registers] I split between command and topic index (9 pages each), because I find it annoying to have the commands between the topics. I also include the topics that are mentioned in titles in the index, because I hate it if I must look in two places. (Otherwise I wouldn’t think about omitting the sections from the ToC.) At the moment there‘s also an index of todo items, but that will disappear before print. [Glossary] There’s a short dictionary of technical terms in the appendix (8.5 p.). Each lemma is also included in the index. Should I add a list of abbreviations? (TDS, TEI, OCG, RAL, PDF, SVG…?) They’re in the index and explained where they matter – I don’t think the meaning of many abbreviations like file types is important. [Other lists] Should I include a list of colors, like the output of \showcolor[crayola]? (I think it would only bloat the book, and everyone can create the list themselves.)

Hi Keith, since both cases are caused by names with accents, did you try to add hyphenation exceptions for those? Such cases are probably not covered by English hyphentation rules.

[NTG-context] Re: Par Builder Tests
Hi all!
Using the example below I have completed a test using a larger book.
This time I downloaded War and Peace from the Gutenberg Project and
extracted the individual xhtml files for Context.
I played around with the setups for the align:pass:test4 code below, as
Hans suggested, and it was changing the \tolerance value which made the
difference. Increasing the \tolerance value to 1000 eliminated all
overfull hboxes but still left 79 underfull hboxes. I continued to
increase the \tolerance value up to 6600 and was left with two overfull
hboxes. One with a badness of 6641 (warAndPeace1.png) and one with a
badness of 1097 (warAndPeace2.png). Above the \tolerance of 6600 only
warAndPeace2.png was left with a badness of 1097. Both of these
underfull hboxes were at the beginning of a paragraph - "To his Honor"
in the first png and "Well, you see," in the second png. I not sure a
reader would spot the second png badness but the first is noticeable to
my eyes.
I'm very pleased how the book has turned out, all 1668 pages of it as an
approximately 13cm by 20cm book. The pdf is 4MB and each run in ConTeXt
takes about 10 seconds on my M1 mac mini.
I'm interested in seeing how \setupalignpass develops and learning more
of how to use it.
Best Wishes

[NTG-context] Par Builder Tests
Hi all,
At the end of June, Hans uploaded a new lmtx version which included
improvements to par building which he and Mikael had been working on in
math mode. Hans suggested in the online chat that these improvements may
be useful in typesetting novels. I was keen to try these since I have
typset novels in the past.
I have ran some tests on two novels which I downloaded from the
Gutenberg Project site as epubs and extracted them to get the original
xhtml files which I then typeset in context. I made very little in the
way of changes to the files so that my setup for xml was very simple.
Here are my setups for the layout of the novels showing some trackers
that were used as well:
\definepapersize[pagee][width=5.06in,height=7.81in]
\setuppapersize[pagee]
% XML setups here
\startsetups[grid][mypenalties]
\setdefaultpenalties
\setpenalties\widowpenalties{1}{150}
\setpenalties\clubpenalties {1}{150}
\stopsetups
\setuplayout[
width=10cm,
topspace=0.5in,
backspace=2.0cm,
header=7.5mm,
footer=0.25in,
location={middle,middle},
vs=2,
grid=yes,
setups=mypenalties
]
%\enabletrackers[makeup]
%\enabletrackers[builders.hpack.quality]
\enabletrackers[builders.hpack.overflow]
%\enabletrackers[layout.vz]
%\enabletrackers[paragraphs.passes]
\enabletrackers[paragraphs.passes=summary]
%\enabletrackers[paragraphs.passes=details]
\setupalign[granular]
%\setupalign[nothyphenated,hz,verytolerant]
%\setupalign[vertical,height]
%\setupalignpass[decent]
%\setupalignpass[quality]
%\setupalignpass[test1]
\setupalignpass[test2]
%\setupalignpass[test3]
%\setupalignpass[test4]
%\setupalignpass[test5]
%\setupalignpass[optional1]
%\setupalignpass[test2b]
\starttext
\setuppagenumbering[location={footer,middle},alternative=doublesided,state=start]
\setcounter[userpage][1]
%\showmakeup[vbox]
%\showlayout
\dostepwiserecurse{0}{30}{1}{
\xmlprocessfile{mysetups}{/path to xhtml
files/4439720318703948998_84-h-\recurselevel.htm.xhtml}{}
}
\stoptext
Below are the result showing the number of overfull boxes for these
novels using the setups in the file spac-imp-tests.mkxl . See the manual
Low Level - Lines
Test Novel1 Novel2
Test1 70 35
Test2 30 8
Test3 62 23
Test4 89 40
Test5 28 9
Optional1 55 19
Quality 74 32
Decent 39 11
From these initial tests one can see that Test2 gave the lowest number
of overfull boxes. So I edited test two, ran it, and the results are below.
Test Novel1 Novel2
Test2b 11 0
My setup for test 2b is as follows:
\startsetups align:pass:test2b
\pretolerance 100
\tolerance 200
\parpasses 3
classes \indecentparpassclasses
threshold 0.025pt
tolerance 800
extrahyphenpenalty 50
next
threshold 0.025pt
tolerance 900
adjustspacing 3
adjustspacingstep 1
adjustspacingshrink 10
adjustspacingstretch 15
next
threshold 0.025pt
tolerance 1000
adjustspacing 3
adjustspacingstep 1
adjustspacingshrink 20
adjustspacingstretch 40
emergencystretch .25\bodyfontsize
\relax
% \linebreakpasses\plusone
\stopsetups
The only difference between test 2 and 2b are that I increased the
tolerance in each of the three passes.
In novel 2 this was successful in eliminating the overfull boxes but not
in Novel 1 although I noticed that majority of overfull boxes were above
1pt with the largest about 12pt in Novel 1.
I am at the stage now where I need some kind of strategy to
reduce/eliminate overfull boxes, other than changing the tolerance, and
I'm hoping for some advice from the community. Suggestions for further
reading particularly on the commands in \setupalignpass and their usage
would be appreciated and on the best way to tackle overfull boxes.
Best Wishes

That’s funny.
I replaced the text by \TeX and published it here:

But is it possible to fill a path (e.g. an lmt_outline) with a

Here's something to get you and Keith starting:
\startMPpage
picture p ; p := lmt_outline [

textext("\TEX")
withpatternscale (1/20,1/20)

\stopMPpage
so the trick is to come up with a pattern that has the right size

Re: [NTG-context] Help with typesetting footnotes in an HTML document
Hi Denis,
Thanks for the code, I shall give this a try.
To get the html file I convert a docx file using a wordpress multisite
app called Pressbooks, a book content management system for book
publishing in various formats such as the web, pdf, epub and various xml
flavours (see pressbooks.com). My interest was that docx files could be
imported into pressbooks, edited and then exported as html which I then
used in ConTeXt to produce pdf. Pressbooks has an open source option and
they give instructions on how to self-host on a local web server, which
is what I have done (see pressbooks.org). It is, I suppose, like using a
sledgehammer to crack a nut, and the html files produced are quite
complicated. I'm still in the experimental stage with it.
Before trying out Pressbooks, I had previously produced two
books(novels) by converting docx files to epub using an epub extension
to Libre Office, then edit/clean-up the epub using Sigil epub editor.
Finally I extract the individual xhtml files and input into ConTeXt.
That was much easier and the files much less complicated, however those
books did not have footnotes so I shall have to check that out in Sigil.
I'm still experimenting to get a simple workflow for the conversion of
docx files to simple (x)html files.
Thanks again for the code.
Best Wishes
Keith

Fair comment Denis.
I decided to try the lookup based approach on pages 85 - 86 of the xml

the xml manual a wee bit difficult in places since xml is outside my expertise.
I attach my tex and html files which should save some copy and pasting.

Re: [NTG-context] Absolute positioning of \startcombination... \stopcombination
Thanks for your reply Pablo. I didn't see it till just now because for
some reason it ended up in my junk folder, along with a number of other
ConTeXt messages. You will probably have seen my reply to the list with
the three solutions, now we have four!
Yep, I know that A4 is the default page size and I always start with
that but sometimes I play about with page sizes when typesetting and so
can just change when coding.
In the document I'm working on, some pages will only contain images
and/or combination of images so I went down the Layers route since this
also allows me to absolutely position these images on the page.
Thanks again for your help!

\setuplayout
[backspace=2.5cm,
topspace=1cm,
height=28cm,
width=17cm,

[x=.5\textwidth, y=.5\textheight]
%\setupbackgrounds[page]
\setupbackgrounds[text]
[background=test3]
\starttext
\setlayer[test3][location={middle}]
\framed[offset=overlay]{{\startcombination[nx=3,ny=1,distance=15mm]
{\externalfigure[cow][width=15mm]}{}
\rotate[rotation=90]{\externalfigure[cow][width=15mm]}{}
{\externalfigure[cow][width=15mm]}{}
\stopcombination}}
\null
\stoptext
BTW, A4 portrait is the default page size.
\setupbackgrounds is the standard way to place layers.
Page and text centering would require different positions (I have
commented out the option for page centering).
I hope it helps (since I’m not sure I’m getting your point here),
Pablo

[NTG-context] Absolute positioning of \startcombination... \stopcombination
Hi,
I would like to position a combination of images where the centre of the
combination coincides with the centre of the text area of a page. In the
example below I have made the combination into a layer thinking that
this would be the easiest way to position it where I wanted. However to
position in the centre of the page I would need to know the size of the
combination and use this to calculate the x and y values for positioning
of the layer. I have looked at the Wiki page on image size of
combinations but still cant figure out how to do it. Any suggestions on
how to go about this or is their a better way?

[NTG-context] Graded Transparency in MetaFun
Hi all
I'm trying to create graded transparency over an area similar to the
effect produced using lmt_shade, where one colour goes to another colour
over a continuum, but with graded transparency we would go from say 0 to
1 transparency, for a single colour. See the MWE below.
I have tried this by creating a loop which draws a linear path, yshifted
the thickness of the pen, with transparency calculated for each step
over the a predetermined height on the page. I have also tried a similar
way for a circular path but in this case the path is repeatedly drawn
scaled in a loop. The MWE below works OK but when I zoom into the graded
transparency areas lines begin to appear which would suggest that their
is a better way to do what I want. This is borne out if you zoom into a
lmt-shade area, one colour smoothly becomes another colour. I've put
examples of this in the MWE. I'm guessing the way lmt_shade areas are
drawn is the way to go. Is this likely to be easy to code for what I
want to do?
Best Wishes

Hi Tommaso I use TeXworks with ConText stand alone LMTX. To set it up to run context do the following. Open TexWorks and then click on TexWorks in the menu bar then Preferences.

Re: [NTG-context] Problem with a defined colour in MetaFun
Hi Wolfgang,
Thank you for your reply. I did as you suggested but it still never
worked. However it did make me delve further into the Metafun,
LuaMetaFun and the Colouring ConTeXt manuals where I found examples of
the *resolvedcolor* helper which I used as follows:
definecolor [name = "myColor", r = uniformdeviate(1), g =
uniformdeviate(1), b = uniformdeviate(1)];
for loop..
fill unitsquare xscaled 5cm yscaled .5cm shifted (7cm,i*cm)
withcolor(r[resolvedcolor("myColor"), white]);
endfor;
I also found the *namedcolor* helper and I could use it as follows:
fill unitsquare xscaled 5cm yscaled .5cm shifted (1cm,(2*i)*cm)
withcolor namedcolor("myColor2") ;
However, for some reason it did not work in:
fill unitsquare xscaled 5cm yscaled .5cm shifted (7cm,i*cm)
withcolor(r[namedcolor("myColor"), white]);
//
Thanks again for your suggestion//
Best Wishes
Keith//

Re: [NTG-context] Setting up zint on a mac with macOS Montery Version 12.3.1
Hi All
I created the symbolic link as suggested by Bruce and Luis and still got the
error message
optional> unable to locate library 'libzint'
in my text editor. I use TeXworks. However, I thought I would try running from
the Terminal app and it worked. It found libzint and output the pdf with both
barcodes and the qrcode. I have no idea why it works in the Terminal and not
TexWorks, I'm guessing I have a path issue which I need to investigate.
Notes
1) My machine is a mac-mini-M1 with macos Monterey and I'm running the latest
ConTeXt version
2) Bruce noted that my Homebrew was installed in a non-standard location so I
checked on the Hombrew website and it is installed in opt/homebrew for Apple
Silicon i.e the M1 chip. Maybe Bruce's homebrew was installed on an earlier
version.
Thanks to Luis and Bruce for their suggestions.

Hi All
I have been struggling today trying to setup and use the Barcode module zint in
ConTeXt and failed. I have followed the instructions on the wiki
(https://wiki.contextgarden.net/Barcodes ) but with some changes as follows.
Which maybe why I failed.
1) I downloaded Zint using Homebrew since I'm using macOS, and installed it
according to the instructions.
2) Since I'm using LMTX I looked for the file libzint.dylib and found it in
/opt/homebrew/Cellar/zint/2.10.0/lib . This is different from the path given on
the wiki. The directory contained three files, two of which were aliases,
libzint.2.10.dylib and libzint.dylib, and an exe file libzint.2.10.0.0.dylib
You have Hombrew installed in a non-standard location. Mine is in
/usr/local/Cellar with the executables linked into /usr/local/bin.
But, assuming other Homebrew commands work when run from Terminal then you
might still be okay.
3) I created the path $TEXROOT/tex/texmf-osx-64/bin/lib/luametatex/zint and
copied libzint.2.10.0.0.dylib into but replaced dylib with 'so' as suggested on
the wiki instructions. So I basically added lib/luametatex/zint to
texmf-osx-64/bin .
"Yes" to creating the path but "no" to copying. Create a symbolic link instead.
So, in Terminal:
$ cd $TEXROOT/tex/texmf-osx-64/bin/lib/luametatex/zint
# In my case I used the following:
$ ln -s /usr/local/Cellar/zint/2.10.0/lib/libzint.dylib libzint.so
# For you with Homebrew in a different location, try:
$ ln -s /opt/homebrew/Cellar/zint/2.10.0/lib/libzint.dylib libzint.so
Then steps 4 and 5 as below. I ran the MWE below: the ISBN worked, the ISBNX
didn't, the QR code did. This is on Monterey.
4) I ran mtxrun --generate to update the database.
5) I ran the MWE below but no barcode appeared. The console output shows:
modules > using user prefixed file 'libs-imp-zint'
modules > 'zint' is loaded
however further down the output it gives:
optional> unable to locate library 'libzint'
I have tried renaming libzint2.10.0.0.so to libzint.so, but still no barcode.
Is their something I am missing? Tips or hints appreciated.

Since "a picture paints a thousand words", I attach a pdf showing the
results of the execution of the code.
Are these bugs or... ?

Hi
In the code below you will see that I have created a closed path and
performed scaling, and shading on the path with lmt_shade [ ]. I have
noticed a few features which may or may not be bugs depending on
whether scaled is applied to the path within the square brackets or
outside.
1) Applying scaled to the path within the square brackets and
incrementing the radius key I can see the shaded areas changing,
however the first two shapes show incorrect scaling and have ragged edges.
2) When scaled is applied outside the square brackets all shapes are
the same size and no ragged edges, however the shading is not showing
correctly with increasing radius.
Am I missing something?

Thanks for your reply Hans. I half suspected that the ARM version was experimental but thought I should report it anyway.

[NTG-context] Possible problem with context using the ARM 64bit download for Apple Silicon M1
Hi all
I have been using ConTeXt (X86 64bits) on my mac mini Apple Silicon M1
and it works well using Rosetta translation for the M1. I recently
installed the ARM 64bits version (separately from the X86 64bits
version) which I assume does not require translation using Rosetta.
However I had a error with the lmt_shade command in the ARM 64bits
ConTeXt verson but not in with the X86 64bits version of ConTeXt. The
MWE is shown below. This is actually taken from the LuaMetaFun manual. I
also noticed that some figures are missing in the manual (Chapter 7,
Shade) which is part of the ARM 64bit tree but not in the manual in the
X86 64bits tree.

I now see I can simplify some lines of the code:
pp := ((xpart a[i])/cf*cm, (ypart a[i])/cf*cm); now becomes pp:= a[i];
and
pp := pp --- ((xpart a[i+1]/cf)*cm, (ypart a[i+1])/cf*cm); now
becomes pp := pp --- a[i +1] ;
However I still have the problem in the calculation of xcoord and
ycoord which are used in the creation of path pp:
for squig = 1 step 1 until 15:
xcoord := uniformdeviate(1) - 0.5 + (xpart a[i]/cf);
ycoord := uniformdeviate(1) - 0.5+ (ypart a[i]/cf);
pp := pp .. {curl 100}(xcoord*cm, ycoord*cm);
endfor;
I'm adding a small random amount to the x and ypart of the pair a[i]
to produce a path that is like a squiggle (gribouiller in French,
according to Google). I have to use cf to convert to the x and yparts
to centimeters since they seem to loose the centimeter units on
separation. I can't see anyway round this, or am I missing something?

Hi,
I have been using xpart and ypart to extract these values from
pairs of points in a path but I wasn't getting the correct result.
I was expecting:
pair (2cm, 11cm) to give xpart 2 and ypart 11
However I was getting:
pair (2cm, 11cm) -> xpart 56.6929 and ypart 311.8096
After much head scratching and reading the MetaPost and MetaFun
manuals, I realised that the units of xpart or ypart are in
Postcript points or Big Points (bp), and 1 bp is 1/72 of an inch,
and thus to get the values of xpart or ypart in cm I would have to
use a correction factor. I had made the assumption that since the x
and ypart in the pair was in cm that the result would be in cm, but
I see now that this is not the case. Will I have to continue doing
this or is there some magic within MetaFun which takes account of
the units in a pair and outputs the result of x and ypart in the
same units?
The MWE belows shows what I have been doing.

MetaPost (MetaFun) is taking care of everything regarding units. As
you ave discovered, everything is translated to a unique internal
dimension. So you can write:
a := (1cm,2in) ;
with no problem. The « cm » and « in » parts of the expression will
become numbers to translate this number on the right unit.

confirmation from the snippet. Hans uses the correction factor cf on the

and not as centimeters as in the pair. I maybe didn't make this clear in
my original query.
Thanks for your patience.

I now see I can simplify some lines of the code:

to centimeters since they seem to loose the centimeter units on
separation. I can't see anyway round this, or am I missing something?

Hi,
I have been using xpart and ypart to extract these values from
pairs of points in a path but I wasn't getting the correct result.
I was expecting:
pair (2cm, 11cm) to give xpart 2 and ypart 11
However I was getting:
pair (2cm, 11cm) -> xpart 56.6929 and ypart 311.8096
After much head scratching and reading the MetaPost and MetaFun
manuals, I realised that the units of xpart or ypart are in
Postcript points or Big Points (bp), and 1 bp is 1/72 of an inch,
and thus to get the values of xpart or ypart in cm I would have to
use a correction factor. I had made the assumption that since the x
and ypart in the pair was in cm that the result would be in cm, but
I see now that this is not the case. Will I have to continue doing
this or is there some magic within MetaFun which takes account of
the units in a pair and outputs the result of x and ypart in the
same units?
The MWE belows shows what I have been doing.

MetaPost (MetaFun) is taking care of everything regarding units. As
you ave discovered, everything is translated to a unique internal
dimension. So you can write:
a := (1cm,2in) ;
with no problem. The « cm » and « in » parts of the expression will
become numbers to translate this number on the right unit.

Re: [NTG-context] new upload
Hi, I'm planning in the next few weeks to retire my 2012 16GB Mac mini which has served me well with ConTeXt (and other software) over these past few years. I was planning on getting the new entry level MAC min M1 with 8GB unified memory but I see that there will be no ConTeXt binaries for these new M1 chip Macs. Would it be possible for a ConTeXt user like myself to build the binaries on my proposed new Mac? I'm not a computer professional.

I have been playing about with an example from this site
https://tex.loria.fr/prod-graph/zoonekynd/metapost/metapost.html

right. Thanks for spotting it. I'm beginning to appreciate where the Fun

Hi Keith,
It took me a while before I saw it, but I think you wanted to type in
z0 = (60,60);
z1 = z0 rotated 120;
z2 = z0 rotated 240;
instead of
z0 = (60,60);
z1 = z0 rotated 120;
z2 = z1 rotated 240;
because the latter puts z2 at z0, resulting in a path that is a straight line. The
fact that AR displays anything at all is probably some form of correction like
"fill of empty path == single pixel line”.

draw lmt_shade [
path = unitsquare xscaled width yscaled height,

1. When you need page backgrounds you can use a overlay and don't have
to create a layer for it.
2. Use unitsquare for your bars which has the origin in the lower left
corner because fullsquare has the origin in the center (look at page
383 in the metafun manual).

[NTG-context] Text on curves
I have been trying to typeset text onto curves and have been successful with the help of the MetaFun manual, and the followtext command which I saw in some correspondence between dr Hans van der Meer and Hans Hagen on the mailing list in January this year ( the subject was Double Follow Tokens). The followtext command seems to used for a simple line of text and if I increase the number of words in the line the font size is reduced to make it fit to the length of the curve (see MWE below). I would like to typeset complete paragraphs on the curve(s) and the only way I see of doing this without the font size changing is to manually create each line separately. Is their a way where this can be done by MetaFun automatically rather than manually? It would be really nice if I could create a number of curves and then MetaFun typsets a paragraph of text on to them. Also, can other options be used with followtext e.g. \input file? I'm a complete novice with MetaFun so any advice appreciated.

Re: [NTG-context] First example in xml-mkiv.pdf
