[NTG-context] startup error
Hello everyone, I am coming back to Context after a while. I have updated ConTeXt LMTX, everything seemed to go well. I have the following problem: If I run: context Hello-world.tex I get the message "startup error : no format file given, quitting" I am clueless!

\uniqueMPgraphic{polygoneregular}}
where the variables are set with the \settupMPvariables command or as

where the variables are set in the optional argument for
\uniqueMPgraphic.

You can use the variable OverlayWidth to obtain the width of the
overlay, which is determined by the provided text. You can use it as
follows:
\setuplayout

path p,p',q,q';
w:=2OverlayWidth;
p := (0,0.1cm) -- (w,0.3cm);

p':= (w,1.3cm) -- (-0.4cm,1.4cm);
q':= (0.3cm,2.4cm) -- (0.2cm,-0.3cm);
pickup pencircle scaled 1mm;
drawoptions(withcolor 0.3white);
draw p; draw p';
draw q; draw q';
pair A; A:=q'intersectionpoint p';
pair B; B:=q intersectionpoint p';
pair C; C:=p intersectionpoint q;
pair D; D:=q'intersectionpoint p;
path s; s:= A--B--C--D--cycle;
fill s withcolor .8white;
\stopuniqueMPgraphic
\defineoverlay

\defineframed

\starttext

Great ! Thank you very much, Marco ! I saw the use of the numeric
variable OverlayWidth and also all your improvements
like drawoptions, defineframed ... in preamble.

Another problem I have is related to the positioning of minus signs

Hi Janne,
With \dfrac it looks good.
With \fraction the minus sign is on the top of the fraction.

I read with care (maybe) your code above, Wolfgang (thanks again !) et
had a look in programming in lua to get a better idea of the object
table, new in lua too :-)
I have some more questions :
- when one create a table doing this : userdata=userdata or {}, is it
only to be sure that userdata is not actually a variable which
exists (with
a non nil value) ? Less safely we could write : userdata={} ?
- arguments for the user.data.table function are given as strings :
#1 and changed in numbers in the body of the function. I noticed that
it was possible to
give numbers directly. is there always better to do like this ? (enter
strings et use tonumber)
- I found the command \define in context garden and saw it's the same
than \unexpanded\def , there is a link to the définitions of the TeX
primitives but
I could'nt find \unexpanded\def (\def was very instructive however).
- I changed slightly the code to obtain a range (x between min and max
with a step) and to choose a round-way.
I failed to find a context way to get rounded numbers, so I did a
workaround (a another function) with help from programming in lua. I
would like a more straight (context) way.
Here is the code :
\startluacode
-- userdata = userdata or {}
-- userdata[roland] = userdata[roland] or {}
userdata=userdata or {}
userdata[roland]=userdata[roland] or {}
local roland = userdata[roland]
function roland.f(x)
return math.log(x)
end
function roland.round (number, approx)
local power = 10^(approx or 0)
context(math.floor(number * power + 0.5) / power)
end
function roland.table(min,max,step,approx)
local min = tonumber(min)
local max = tonumber(max)
local step = tonumber(step)
local nbrcol = tonumber((max-min)*(1/step)+2)
local approx = tonumber(approx)
context.starttable({string.format(|*{%d}{l|},nbrcol)})
context.HL()
context.VL()
context(x)
for i=1,(nbrcol-1) do
context.NC()
context(min+(i-1)*step)
end

There can already be stuff in userdata that you don't want to loose.
OK.
- arguments for the user.data.table function are given as
strings :
#1 and changed in numbers in the body of the function. I noticed
that
it was possible to
give numbers directly. is there always better to do like this ?
(enter
strings et use tonumber)
Depends on if you want to catch errors. Forgetting an argument (or
an empty one) when a number is expected results in ,, which triggers
a Lua error, while with ,, you can intercept the empty string and
default.
Hans
OK. Thanks !

[NTG-context] to pass an argument in a macro
Bonjour,
I am new in ConTeXt. I love its features. I need some (or a lot of) help.
I tried to get a macro which compute some values for a math function. With help
from the wiki ConTeXt Garden and some time I could do that
- write my function userdata.f
- write another function to put the values in a table : userdata.tabf
- put both of them in a file /Users/rolandt/context/mesfonctionsluatex.lua
- In a file.tex, I use that macro :
\def\tabf#1#2%
{\startluacode
dofile(/Users/rolandt/context/mesfonctionsluatex.lua)
userdata.tabf(#1,#2)
\stopluacode}
Here are the functions:
-- fonction cube
-- on utilise l'espace de nom userdata
userdata=userdata or {}
function userdata.f(x)
context(x*x*x)
end
-- fonction tabf
-- which makes a table , compute 6 values, b=first x, c = step
userdata=userdata or {}
function userdata.tabf(b,c)
context.starttable{*{7}{|l}|}
local b=b
local c=c
context(\\HL)
context(\\VL x ) for i=1,6 do context(\\NC .. b+(i-1)*c) end
context(\\VL..\\AR)
context(\\HL)
context(\\VL f(x) ) for i=1,6 do context(\\NC)
context(userdata.f(b+(i-1)*c)) end
context(\\VL..\\LR)
context(\\HL)
context.stoptable()
end
I am sure it could be much better but it works !
Evidently I need a third argument to be able to choose how many values compute.
I failed completely (I don't understand how arguments are passed).
I tried things like : context.starttable{*{%s}{|l}|,a} but ... fatal error :)
I would appreciate some help or what to read to improve understanding that kind
of things.
Best regards,
Roland

Do \luaexpr{1/3.8} and \ctxcommand{format(@0.3f,1/3.8)} return

Bonjour,
\ctxlua{context(type(\luaexpr{1/3.8}))} gives : number
