[NTG-context] Formula has excess vertical spacing when in two column itemize
Hi List,
I am getting better at adjusting the space in enumerations, but I just put a
formula inside an enumeration, and the formula’s vertical spacing became
excessive. I’m not sure how the enumeration caused this problem.
\starttext
Evaluate the following derivatives.
\startitemize[n, columns, two, nowhite, after]
\item\hspace[big] $\frac{d}{dx} x^2$
This is where the solution should be. Text answers look fine, but formulas have
too much space above, below and between lines\dots.
\item\hspace[big] $\frac{d}{dx}\left( x^3 + 2x \right)$
\item\hspace[big] $\frac{d}{dx}\left( x^{-2} \right)$
\item\hspace[big] $\frac{d}{dt}\left( 4t^4 - 3t^{\onehalf} \right) $
\item\hspace[big] $\frac{d}{dt}( 9 - 3t )$
\startformula\startmathalignment
\NC \frac{d}{dt}( 9 - 3t ) \NC= \frac{d}{dt} 9 - \frac{d}{dt} 3t \NR
\NC \NC= 0 - 3\frac{d}{dt} t \NR
\NC \NC= -3\cdot 1t^0 \NR
\NC \NC= -3 \NR
\stopmathalignment\stopformula
\item\hspace[big] $\frac{d}{dp}\left( p^3 - 2p \right)$
\stopitemize
\stoptext
I’m also attaching a file with the above issue followed by the correct spacing
in one-column for comparison.
I’m using LMTX (today’s upload, ver: 2022.10.21 21:13 LMTX fmt: 2022.10.21) on
an M1 Mac.
Any ideas?
Gavin

Hi, I updated lmtx ... there are a few fixes for issues reported on the list. In the perspective of updating math the - otherwise unchanged - mkiv variant has also been updated a little. No new commands, just some (already old) experimental font related features gone and replaced by a combined one inspired by what we do in lmtx. In our opinion on the average it should not come out worse.

Re: [NTG-context] Spacing in \unit - SOLVED
Hans, I made a small mistake in the phys-dim.mkxl file I sent you. I removed a % at the end of lines 469 and 485. Without the %, using alternative=text causes extra space before the unit. A corrected phys-dim.mkxl is attached.

Re: [NTG-context] Spacing in \unit - SOLVED
Hi Hans,
> I'll look into it (with Mikael as some relates to math) once you're done
> playing and provide suggestions and tests.
I’m done playing. Below are tests and suggestions. Sorry it has taken so long
for me to put this together.
Tests
I attached two test files. The first, units-spacing.tex, is for testing spacing
for \unit used in text, inline math, and display math. The second,
units-linebreaks.tex, tests line breaks when \unit. is used in text or in
inline math. Line breaks were not my primary interest, but Max and Alan were
quite interested. My proposed fixes for spacing also fix their concerns about
line breaks.I tried to make these tests match the style of the Test Suite. They
could be included there if they are useful.
Suggestions
I attached my my modified phys-dim.mkxl. All of my changes are commented and
signed with -GP to make them easy to find. Below are comments on the five
issues I addressed (not including line breaks). The first four of these are
fixes.I don’t think any of these fixes are controversial or require new
options. The fifth, regarding the space around the \times in scientific
notation, might be an appropriate option, rather than a universal fix.
1. The \cdot in units should not have space around it.
These lines produce the \cdot between units, one is for the default \cdot, the
other when the separator=cdot option is used. I’m not entirely sure why they
are separate. Now, in math mode, the \cdot is changed to an ord. (ll. 392-393)
\protected\def\phys_units_separator
{\ifcsname\??unitseparator\unitparameter\c!separator\endcsname\lastnamedcs\else\ifmmode\mathord\cdot\else\cdot\fi\fi}
% Made \cdot an "ord" in math mode -GP
\installunitsseparator\v!normal{\ifmmode\mathord\cdot\else\cdot\fi} % Made
\cdot an "ord" in math mode -GP
2. Space is needed between number and units
To get the thin space between the number and the units (ll.412-418)
\protected\def\phys_units_space
{\ifmmode
\thinspace % let the atoms do the work. Right now atoms aren't doing the
work, so I put in a \thinspace -GP
\else
\unskip % weird, why is unskip needed
\ifcsname\??unitspace\unitparameter\c!space\endcsname\lastnamedcs\else\unitsmediumspace\fi
\fi}
3. Space is needed after the units, before the next relation, binary operator,
etc. Right now there seems to be no space added between the new dimension class
and the relation and binary operator class. Until the space around the
dimension class is fixed, The units should not be assigned to the dimension
class, which means removing the code that sets units to this class. (ll.
618-623)
\def\phys_units_start
{\ifmmode
\dostarttagged\t!maction\t!unit
% \mathatom % I removed this because the correct spaces after dim haven't
been set (e.g. dimbin, dimrel) -GP
%\s!leftclass \mathdimensioncode
%\s!rightclass \mathdimensioncode
\bgroup
\else
\dostarttagged\t!unit\empty
\fi
\let\phys_units_finish\phys_units_stop
\let\phys_units_start\relax}
4. Remove hardcoded backspace before the solidus in units. (If this space
should be tighter, it probably should be dealt with for every solidus, not just
the solidus in \unit the unit command.) (ll.412-418)
\permanent\protected\def\unitsSOLIDUS
{%\ifnum\c_phys_units_state=\plusone % suffix % Removed three lines to
eliminate backspace before / -GP
% \unitsbackspace
%\fi
{/}%
}%\unitsbackspace}
5. I think the \times in scientific notation should not have extra space.
Everyone who commented on the mailing list agreed. However, I’m not sure that
this is a universal desire, so it might be good to add an options, like
scispace=normal for the usual binop space around the \times and scispace=tight
for no extra space around \times. The changed line in phys-dime.mkxl used to
add space around the \times in text. Now, instead, it removes the space around
the \times in math by making the \times an ord. (ll. 170-172)
\permanent\protected\def\digitstextbinop#1% assumes preceding
{\ifmmode\mathord#1\else\nobreak#1\fi} % Removed space around binop (\times or
\cdot) in \units -GP
%{\ifmmode#1\else\fourperemspace\nobreak#1\fourperemspace\fi} % This is the
old line with spaces -GP
Those are my five suggestions. Thanks for looking at spacing in \units!

Hi,
playing around with \definebodyfontenvironment with latest LMTX,
I found this possibly buggy behavior:

\starttext
normal {\tx tx} {\small small}
\stoptext
With \definebodyfontenvironment[12pt][x=6pt] I can resize \tx fine,
but for \small it doesn't work.
it has to do with the fact that we have font clases and some parameters
are bound to it.
\setupbodyfontenvironment
[pagella]
[12pt]
[x=4pt,
small=4pt]
\setupbodyfont[pagella,12pt]
\starttext
normal {\tx tx} {\small small}
\stoptext
that will work. You can say \fontclass to see what you got after a
\setupbodyfont.
I'll add
\setupbodyfontenvironment
[all]
[12pt]
[x=4pt,
small=4pt]
as option (assuming we have no performance hit).
x xx : dynamic
small big : more static (trigger some definitions)
when we decide to go 'compact fonts' we can review this. We can then
also decide to get rid of the old design size subsystem (only lm uses it
unless one does 'modern' and there are other ways.)

Hi Leah,
I don’t know whether it may be a bug, but this works:
\definebodyfont[12pt]
\definebodyfontenvironment[12pt][small=100pt, x=100pt]
\setupbodyfont[12pt]
\starttext
normal {\tx tx} {\small small}
\stoptext
It might be that \small could be hardcoded by default.
Sorry for changing sizes, but I wanted to know for sure it was working.
Just in case it might help,
Pablo

Re: [NTG-context] Backgrounds has changed in latest lmtx
Hi Thomas,
Your example does indeed show the issue I had reported on with Simpleslides:
the backgrounds of the slides are not as expected.
So it seems that beginning with version 2022-10-15 something has changed with
Metapost or the background mechanism.
