In lang-imp-indic.lua we find a definition of the transliteration of "ṁ" from IAST transcription into Nagari ("deva"):

 ["ṁ"] = "ं"

 There is nothing wrong with this, since the ṁ is in use, but the standard transcription (acc. to  IAST), also in wide use, is "ṃ".

 I suggest adding ["ṃ"] = "ं" to make the mechanism useful to both camps.

Hi, I made a list of 4-dimensional vectors using the following code. \startluacode local matT = {{0,0,1,1/3},{1,0,0,1/3},{0,1/2,0,1/3},{0,1/2,0,0}} local matOld = {{1/4},{1/4},{1/4},{1/4}} local matNew = {} local matHistory = {} table.insert(matHistory, matOld) for i = 2, 15 do matOld = matHistory[i-1] matNew = mtx.product(matT, matOld) -- mtx.typeset(matT)context("\\times")mtx.typeset(matOld) -- context(" = ") mtx.typeset(matNew) context("\\blank") table.insert(matHistory, matNew) end \stopluacode I’d like to draw a line graph of the data in matHistory to show the change of each component of 4-dimensional vectors. How can I draw it in LuaMetaFun? In the manual, data is already given in the example. How can bring the data made in lua to ConTeXt? Thank you. Best regards, Dalyoung

Hi Julin !

At first glance, it appears that the font declared and the font used are not the same. This is why, during compilation, ConTeXt falls back on LatinModern and prints the numbers in Roman.

As Wolfgang rightly points out, it would be necessary to identify precisely which system font actually allows Japanese to be rendered. The following commands must therefore be executed:

mtxrun --script fonts --list --pattern=“Noto”

mtxrun --script fonts --list --pattern=“JP”

mtxrun --script fonts --list --pattern=‘CJK’

and definitely install a “real” font that renders kana and nihongo mode properly (try ipaexmincho). And try this :

\definefontfamily[jp][rm][IPAexMincho] \setupbodyfont[jp] \setscript[nihongo]

\starttext これはIPAex明朝体による日本語のテストです。 \stoptext

Or, if it fails, try this code :

% 1) Fallback first \definefallbackfamily[main][rm][ipaexmincho] [preset=range:japanese,force=yes]

% 2) Main family follows \definefontfamily[main][rm][TeX Gyre Pagella]

\setupbodyfont[main,10pt] \mainlanguage[en] \setscript[nihongo]

\starttext This is English text.

これはIPAex明朝体による日本語です。 \stoptext

Hope this helps.

I am new to ConTeXt (but comfortable with LaTeX) and was trying to figure out how to have letters of different scripts in the same document.

I tried to have a Japanese only document using the snippet in this thread https://mailman.ntg.nl/archives/list/ntg-context@ntg.nl/message/QCXFTDHLPDS3...

Like this:

``` \definefontfamily [noto-jp] [rm] [Noto Serif CJK JP] \definefontfamily [noto-jp] [ss] [Noto Sans CJK JP] \definetypeface [noto-jp] [mm] [math] [pagella] [default]

\setupbodyfont [noto-jp]

\mainlanguage [ja]

\setscript [nihongo]

\starttext

I got all the fonts available in my computer, but the generated pdf contains only the Latin part. Just few numbers: 873684694. I don't know what I am doing incorrectly here.

Would anyone be able to help me out? I eventually want to make a document which has multiple scripts in it with English as main language.

I tried skipping some of the pdfs at https://wiki.contextgarden.net/Documentation, but am not sure if I missed the relevant section.

Thanks. ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki!

Dear Hans, Thank you for your reply.

...

In the manual, data is already given in the example.

which example are you referring to

I mean the example in the Axis section like this: list = { [ connect = true, color = "darkred", close = true, points = { (1, 1), (15, 8), (2, 10) }, texts = { "segment 1", "segment 2", "segment 3" } ],

...

How can bring the data made in lua to ConTeXt?

userdata.yourdata = matHistory

and then access that with lua calls

OK. I will try to save it in lua and reload it into MetaFun. I remember a similar method and a code which you helped me a year ago. I hope that I go a right way. Thanks again. Best regards,

Now I got the working code. It calculates the list of 4-dimensional vectors and draw a line graph which shows the change of each component of vectors.

Here is the code. There may be several points which can be written more nicely.

Thanks again.

You have to be more careful here; you do MP = { } which overloaded an official global namespace. That will backfire at some point. You still have mtx as global alias without testing if it exists. Don't do that, because one never knows if context itself will use that namespace (ctx, mtx ...). Basically we don't expect users or modules to define global tables at all, and if they to one has it coming. Just use userdata or moduledata (with subtable) or so. I'm not going to rewrite your code but here are a few suggestions: function MP.loadmydata(n) MP.mydata = table.load(n) end function MP.getmydata(i,j) mp.print(MP.mydata[i][j]) end and then % lua("MP = { } MP.data = table.load('tempList.lua')") ; lua.MP.loadmydata('tempList.lua') ; with % yy := lua("mp.print(MP.data[" & decimal i & "][" & decimal j & "])"); yy := lua.MP.getmydata(i,j); which gives you an easier way to check for instance of the data is ok or mess with it at the lua end. Watch how we accept ' as string delimiter ... by default luametafun is set up to accept ' and " as in lua.
