You can save extracting the xparts and yparts by using direct subtraction of 
pairs and comparing with (0,0) like this:

\starttext
\startMPcode
path cutFirstPart,cutSecondPart;

cutFirstPart := (0,0) -- (232.520001,-427);
cutSecondPart := (232.519998,-427) -- (999,-427);
%cutFirstPart := (0,0) -- (232.520001,-427);
%cutSecondPart := (232.520001,-427) -- (999,-427);

if (point infinity of cutFirstPart) - (point 0 of cutSecondPart) = (0,0) :
  label("same", (1cm,1cm))
else :
  label("different", (1cm,1cm))
fi;
\stopMPcode
\stoptext

*Except* that the example doesn't work with floats that are so close. Changing 
232.52_etc to 332.52_etc works as expected. I'm hoping that this is a "feature" 
of the parser reading in the example at a lower precision than the number of 
decimals provided. For your code, where the different values are created by 
calculation, the two pairs should be recognised as different.

If this is not user error (mine), perhaps this is a win64 build problem?
I can't imagine, as I compile these win binaries here using the mingw 
cross compiler under WLS (1). I also compile native binaries (a little 
slower than the cross compiled but a smaller file) and clang binaries 
(much slower and larger). The farm also has a windows set up now for 
luametatex but I just use the ones I make here. So, what gets shipped, 
the mingw ones, should work ok. (The native ones are part of the the 
backup plan, as on enevrr knows what will happen with mingw, not that 
the compilation is demanding.)

Ok, that is not bad (I think on my already old machine one run took some 
18 seconds for luatex and of course in mkii with pdftex I could watch a 
movie while processing the file.)


The memory footprint also looks ok, especially given all these graphics. 
(in most cases lmtx has a smaller memory footprint.)

Hi Hans,

Thanks for the quick fix of today's upload.
I could typeset your examples with \mathopen, \mathclose and these are great 
features in order to fine tune the spacing in math mode.

Regarding the new command \Uover, I thought maybe it would be more consistent 
to have the usual structure
${1} \Uover {2}$
like the more friendly ${1} \over {2}$ instead of having


That would involve backtracking and be a psin in the butt wrt control. 
One can't have it all.



$\Uover{1}{2}$
which is more like the \frac structure.


Watch out: these are low level primitives (it is actually a set of 
primitives that put stuff on top of each other). The \frac is the 
interfaced variant.



Also a structure like
$\Uover style \textstyle{1}{2}$
seems a little bit far from the usual ConTeXt atmposphere… Would it not be 
possible to have
${1} \Uover[style=textstyle] {2}$
instead?


That is what we have frac for (and one can define veriants that have set 
styles).



In any case, thanks a lot for the constant addition of cute features…
Some of these engine level extensions have been on my list for a while 
and eventually make implementing the user interfaced wrappers nicer (and 
sometimes more robust). Some is actually possible because some engine 
internals are a bit reorganized.

Re: [NTG-context] Use \unit for value and uncertainty

2020-05-09 Thread Otared Kavian 
Hi Benjamin,

Thanks for sharing your nice code, which is very useful.
However I wanted to let you know that it seems it does not work correctly with 
LuaMetaTeX version 2020.04.30 11:10, even though it works fine with ConTeXt 
mkiv.

Best regards: Otared K.

Re: [NTG-context] Use \unit for value and uncertainty

2020-05-09 Thread Benjamin Buchmuller 
I know this is quite an old thread, but here is a minimal parser (\units with 
an “s”) that wraps around \digits and \unit to produce an acceptable output. 

As I frequently need to write ranges (or measures of uncertainty), I find it 
convenient to able to type

\units{4.0 to 5.0 centi meter} 

than 

\digits{4.0}\,to\,\unit{5.0 centi meter}.

Also, the parser will take care of exponents and bracket them accordingly. :D

ranges: keyword “to”: 4.0 – 5.0 cm
SEM:keyword “se”: 4.5 ± 0.5 cm
SD: keyword “sd”: 4.5 (0.5) cm

If no keyword is present, the default behaviour is \unit{…}.

The code is not perfect (and the level of abstraction potentially not yet 
sufficient to make it part of the phys-dim.mkiv source), but maybe helpful.

\starttext

\startluacode
userdata = userdata or {}

function userdata.units(input)

tbl = string.explode(input)

if tbl[2] == "to" then
context.digits(tbl[1])
context.phys_units_space()
context("--")
context.phys_units_space()
context.unit(table.concat(tbl, " ", 3))
elseif tbl[2] == "se" then
local sx1 = string.split(tbl[1], "e")
local sx2 = string.split(tbl[3], "e")
if (sx1[2] == sx2[2]) and not (sx1[2] == nil) then
context("(")
context.digits(sx1[1])
context.phys_units_space()
context("±")
context.phys_units_space()
context.digits(sx2[1])
context(")")
context.digits("e" .. sx1[2])
context.phys_units_space()
context.unit(table.concat(tbl, " ", 4))
else
context.digits(tbl[1])
context.phys_units_space()
context("±")
context.phys_units_space()
context.unit(table.concat(tbl, " ", 3))
end
elseif tbl[2] == "sd" then
local sx1 = string.split(tbl[1], "e")
local sx2 = string.split(tbl[3], "e")
if (sx1[2] == sx2[2]) and not (sx1[2] == nil) then
context.digits(sx1[1])
context.phys_units_space()
context("(")
context.digits(sx2[1])
context(")")
context.digits("e" .. sx1[2])
context.phys_units_space()
context.unit(table.concat(tbl, " ", 4))
else
context.digits(tbl[1])
context.phys_units_space()
context("(")
context.digits(tbl[3])
context(")")
context.unit(table.concat(tbl, " ", 4))
end
else
context.unit(table.concat(tbl, " "))
end

end
\stopluacode

\def\units#1{\ctxlua{userdata.units("#1")}}

Car 1 drives \units{4 to 5.2 kilo meter per hour}.

Car 2 drives \units{30.1 to 40.5 kilo meter per hour}.

Car 3 drives \units{40.= to 50.= kilo meter per hour}.

The average speed was \units{35,000 se 5000 meter per hour}.

[NTG-context] Current version 2020.05.09 08:55 not working

2020-05-09 Thread Otared Kavian 
Hi Hans,

I just updated to the latest version 2020.05.09 08:55 but when trying your 
examples with \mathopenup and friends noticed that ConTeXt is stuck with 

resolvers > lua > loading file 
'/context-osx-64/tex/texmf-context/tex/context/base/mkiv/math-spa.lua' succeeded

or with

context report > file: cont-en-status.html

and other such messages.

Actually even with a simple example like

\starttext
Test
\stoptext

one cannot run the latest version at least on MacOS X (I did remove the texmf 
cache).

When in a Terminal window I issue the commands

context --make -all

I see that there is an error message like:

tex error > tex error on line 2981 in file math-ini.mkxl: ! Undefined 
control sequence

l.2981 \normalsupmarkmode
 \plusone % 2 also disable ^[^+] in text mode 

 

The control sequence at the end of the top line of your error message 
was never \def'ed. You can just continue as I'll forget about whatever was 
undefined.

Best regards: OK

[NTG-context] error during the installation of luametatex
