[NTG-context] Strange behavior in somewhat complex layout

2019-06-23 Thread Andres Conrado Montoya 
Hello list, I'm trying to make something using bits and examples found here
and elsewhere, but I'm hitting a wall. I know there's a flawed logic in my
approach, but I can't figure it out. Any help is appreciated.

Expected behavior of the following MWE:
When starting a new chapter, check if the page is even (left page), if so,
fill it with color, and start the chapter in the next odd page (right
page), removing the header but leaving the footer in that start-chapter
page; and if this is a start-chapter page, use a specific graphic overlay
for the page, but if if not (if its a regular page), use another graphic.

Result:
The header still appears in the start-chapter page, if it comes after the
color filled page. But, if the start-chapter page comes after a regular
(even) page, everything works as expected (no color-filled page, no header
in the start-chapter page).

MWE:

%% START MWE

\definecolor[rojo][h=ED553B]
\definehighlight[rojo][color=rojo]

\startMPinclusions

[NTG-context] CrossWords Puzzles with context

2019-06-23 Thread Jorge Manuel 
After some attempts to build crosswords puzzles with context, I found this 
approach:

1) Create the puzzle with  genxword
https://github.com/riverrun/genxword  

2) Edit the output table and change all {}  to  *

3) Save the table in a file (p.e. crosswords.txt) 

3) In context use this script (Revised By Wolfgang Schuster)

\startluacode
context.startmidaligned()
context.bTABLE( { rulethickness = ".25pt", width = ".8cm", height = 
".8cm", align = "{lohi, middle}" } )
for line in io.lines("crosswords.txt") do
for w in (line .. "|"):gmatch("([^|]*)|") do 
-- print (w)
if w == ' ' then
context.bTR()
elseif w == '.' then
context.eTR()
else
if w == '* ' then 
context.bTD( { frame = "off" } )
context.eTD()
else 
ww = string.match (w, "%d+")
print (ww)
if ww then
context.bTD( { foregroundstyle = "\\bfxx" } )
context("%s",ww)
context.eTD()
else
context.bTD()
 -- context("%s",w)
context.eTD()
end
end
end
end
end
context.eTABLE()
context.stopmidaligned()
\stopluacode

Re: [NTG-context] mkii to mkiv - section numbering with minimal example

Thanks Hans. After some searching in the test suite I found the answer,
which I'll put here in case someone else is searching for it, which is:

\setuphead[section][sectionsegments=section]
\setuphead[subsection][sectionsegments=section:subsection]

which sets up sections to just be numbered with the section number instead
of the part, chapter and section number, and sets up subsections to just be
numbered with the section and subsection number.

Now that I know how to do it I see mkiv is much cleaner on this code and
the change gets reflected in tables of contents etc. This was much harder
in mkii. Thanks again.

[NTG-context] italic correction (before the glyph)

2019-06-23 Thread Pablo Rodriguez 
Dear list,

I have the following sample:

\def\DesiredFont{TeX Gyre Termes}
\definefontfeature[italic][itlc=yes,textitalics=yes]
\setupitaliccorrection[global, always]
\definefontfamily
[mainface]
[rm]
[\DesiredFont]
\definefontfamily
[mainface_corrected]
[rm]
[\DesiredFont]
[features={italic}]
\setupbodyfont[mainface]
\setupitaliccorrection[global,always]
\starttext
\startbuffer[chars]
\startTEXpage[offset=1em]
\dorecurse{26}
{\setupbodyfont[mainface]%
[{\em \recurselevel}]
[{\em \characters{\recurselevel}}]
[{\em \Characters{\recurselevel}}]
({\em \characters{\recurselevel}})
({\em \Characters{\recurselevel}})
\hfill
\setupbodyfont[mainface_corrected]
[{\em \recurselevel}]
[{\em \characters{\recurselevel}}]
[{\em \Characters{\recurselevel}}]
({\em \characters{\recurselevel}})
({\em \Characters{\recurselevel}})
\par}
\stopTEXpage
\stopbuffer
\getbuffer[chars]
\def\DesiredFont{TeX Gyre Pagella}
\getbuffer[chars]
\stoptext

This shows that sequences such as ({\em f}) are corrected with the
closing parenthesis, but not with the opening one.

Wouldn’t it be possible that italic correction could be enabled also
before the italic glyph(s)?

BTW, I wonder why the second definition of \DesiredFont doesn’t change
the font for the buffer used after it.

Many thanks for your help,

Pablo

Hi Duncan,

I guess this may be what you want to do:

\setuphead[part][placehead=yes]
\setuphead[section][sectionsegments=section]
\setuphead[subsection][sectionsegments=section:subsection]
