Can you provide a example where you have problems with \doifdefined etc.

You need at least version 2024.06.14 to get the manuals, if they are 
missing on your system the installed context version is tool old.


Another way to get the manuals is from the Pragma website:

I think if you update to the latest using
sh install.sh
once you are in your ConTeXt directory, you should find it there where
Mikael says it is.

[NTG-context] Faulty PDF output files after updating to version 2024.06.14

[Ralph]

Hi,


while trying out the new version of ConTeXt LMTX (2024.06.14 09:18) I 
encountered some problems related to the PDF output files.


First, I tried to print a single page of the excellent new math manual 
(many thanks to everyone involved in creating it, it’s great for 
beginners like me and surely for experienced users too), but I noticed 
that all of the extensibles in the formulas (like the bar in \frac, 
\sqrt, long integral signs, and probably more) have disappeared. 
Everything else was printed correctly.


After investigating, I found out that Okular on Linux converts the PDF 
file to PostScript before printing (at least on my system), and I was 
able to replicate this behavior by converting it manually to PostScript 
with Poppler (pdftops in.pdf out.ps) or Ghostscript (pdf2ps in.pdf out.ps).


Printing from Firefox was not affected for me as it did not convert to 
PostScript.


I was unable to reproduce this with my own documents (created with 
ConTeXt LMTX 2024.05.31 18:50), so I decided to try this with the new 
version. And with it, that was indeed reproducible.


To ensure that this is the PDF’s fault, I decided to try this on Windows 
with Adobe Acrobat Reader on a different Computer with another fresh 
installation of ConTeXt. But it wasn’t any better:


Adobe Acrobat Reader displayed two different error messages when trying 
to scroll through or zoom in on the math manual:
1. “An error exists on this page. Acrobat may not display the page 
correctly. Please contact the person who created the PDF document to 
correct the problem.”

2. “There was an error processing a page. A number is out of range.”
Sometimes the first one is shown, sometimes the second one.

Additionally, some parts of the manual were blank (they were displayed 
correctly in Okular, Firefox, and many more viewers), I suspect those 
who contain extensibles in formulas. Following example leads to the same 
behaviour:


\setuppapersize[S33]    % Just to make page smaller
\setupbodyfont[modern, 11pt]
\starttext
Hello.
\startformula
\frac{a^2 + b^2}{1} = c^2
\stopformula
\page
Hello.
\startformula
a^2 + b^2 = c^2
\stopformula
\stoptext

The first page is empty in Acrobat Reader, whereas it’s displayed 
correctly in all other PDF viewers I tried. But again, when converting 
to PostScript, the fraction bar vanishes. The second page is fine.


I attached the faulty example.pdf file and some screenshots of it opened 
in different PDF viewers, and of the math manual. The screenshot of the 
math manual opened in Acrobat Reader shows that the second half of the 
page is completely gone. example_pdftops-ps2pdf.pdf is example.pdf 
converted to PostScript with Poppler and then converted to PDF again 
with Ghostscript (attaching the PostScript file isn’t possible because 
of file size). Opened in Okular or other Poppler based viewers you’ll 
see a dot instead of the fraction bar (which gets infinitely smaller 
while zooming-in), and openend in Firefox, MuPDF or Acrobat Reader 
you’ll see a cut off bar.


One last thing, for some reason “\italiansqrt” on page 52 of the math 
manual is converted perfectly fine to PostScript (at least it looks right).


Please let me know if you would like me to provide more information.


Best,
Ralph

The month table layout is hard-coded in line 515 of file t-pocketdiary.lua

The code that decides in which cell to put the '1' of the first day is 
calculated elsewhere and not passed as a parameter.

That rules out a simple fix - you'd need to add a "weekstart" or similar 
parameter and track/act on it in various parts of the code.

Indeed.

Cambria is the reference of course but Pagella is free and we like it. 
We could have gone Lucida but it's not free either (but rather cheap and 
we fixed some in the process). Euler is also nice. We also had Bonum for 
a while (a bit bolder). Of course most fonts share alphabets. The Xits 
font is quite complete but kind of standard boring. We definitely will 
never for a can-of-worms sans for a document like this.


That said: all fonts needed tweaks, some more than others, because there 
is the inconsistent curious mix of font parameters, traditional and 
opentype properties etc to deal with, much of which we published about 
in e.g. TB in the process (as well as in documents in the 
distribuition). There ars also math companion fonts in the distribition 
that fix consistency issues in fonts (we consider most to be frozen).


Concerning complete: many unicode math characters are dubious and we 
wonder what they're used for, if at all while some other handy math 
symbols are missing.

[NTG-context] \xmlinlineverbatim not inline

[Pablo Rodriguez via ntg-context]

Dear list,

I have the following sample:

  \startbuffer[demo]
  
text
  
  \stopbuffer

  \startxmlsetups xml:sample
\xmlsetsetup{#1}{text}{xml:*}
  \stopxmlsetups

  \xmlregistersetup{xml:sample}

  \startxmlsetups xml:text
block: a \xmlverbatim{#1} b\\
inline: a \xmlinlineverbatim{#1} b\\
block: a \xmlprettyprint{#1}{xml} b\\
inline: a \xmlinlineprettyprint{#1}{xml} b
  \stopxmlsetups

  \startxmlsetups xml:element
\tt\xmlatt{#1}{class}
  \stopxmlsetups

  \starttext
\xmlprocessbuffer{main}{demo}{}
  \stoptext

With latest from 2024.06.14 09:18, \xmlinlineverbatim doesn’t display
inline text, but only block text (both with LMTX and MkIV).

Could anyone confirm the issue?

Many thanks for your help in advance,

Pablo
