[NTG-context] define math function with \, inside
Hi all,
I wanted to define a custom math function (similar to log etc.) for
argmax. However, I wanted to have a small space between "arg" and "max"
and limits should work properly. I am using a up-to-date LMTX installation.
Without the first constraint it's easy:
> % old way:
> \definemathcommand[argmax][limop]{\mfunction[argmax]}
> % new way, discoverd by looking into math-def.mkxl
> \definemathfunction[argmax]
However, both methods do not work if I want to have "arg\,max" printed
(error about \endcsname missing). With mkiv the first method works and
can also be found in the wiki[1].
What's the current way to define such a custom math function?
Thanks!

Re: [NTG-context] LuaMetaTeX doesn't find files when symlinked
Max & Hans:
I installed the stand-alone ConTeXt installation just today. It seems
like I have my $PATH set correctly now.
I have been editing ConTeXt and running it within TeXstudio. I had set
up a "user command" to execute arara on LaTeX and ConTeXt files when I
did NOT have the "standalone" version installed. It still works
correctly.
Today, I created a separate "user command" within TeXstudio, and it
points to "/usr/local/ConTeXt_Standalone/context-linux-64/bin/mtxrun"
This command generates the same log output as the example at
https://gitlab.com/islandoftex/images/texlive/-/issues/30.
If I understand this correctly, my OLD user command within TeXstudio is
still finding the TeXlive version of ConTeXt, and that TeXlive version
does have the symlinks mentioned by Max (and BTW, I did NOT create
those, they are part of the default TeXlive installation process!). This
is because my OLD "arara" command has the path to the March 13 version
of TeXlive 2023 version (installed from ISO image, with some updates
using tlmgr already installed).

[NTG-context] LuaMetaTeX doesn't find files when symlinked
Hi Hans,
With the LuaMetaTeX-based ConTeXt wrapper, it's not generally possible
to run ConTeXt from a symlinked binary in another directory. This shows
up if someone makes symlinks in "/usr/bin" so that they can avoid adding
anything to their $PATH.
If you make run a symlink to the LuaMetaTeX-based ConTeXt wrapper, it
looks for texmfcnf.lua relative to the symlink location, not the symlink
target. With the old LuaTeX/kpse-based wrapper, the script would look
for texmfcnf.lua relative to the symlink target.
I know that my description above is terrible, so here's a demo:
$ bin=$(mtxrun --expand-var TEXMFOS | head -1)/*
$ cd $(mktemp -d)
$ ln -s $bin/luatex $bin/luametatex $bin/context $bin/context.lua
$bin/mtxrun $bin/mtxrun.lua .
$ ./context --nofile
$ ./context --luatex --nofile
Running the above commands used to work with the old LuaTeX/kpse-based
wrapper, but it doesn't work any more. I was able to ""fix"" this by
adding the lines
if os.selfpath then
environment.ownbin = lfs.symlinktarget(os.selfpath .. io.fileseparator
.. os.selfname)
environment.ownpath = environment.ownbin:match("^.*" .. io.fileseparator)
else
environment.ownpath = kpse.new("luatex"):var_value("SELFAUTOLOC")
environment.ownbin = environment.ownpath .. io.fileseparator .. (arg[-2]
or arg[-1] or arg[0] or "luatex"):match("[^" .. io.fileseparator .. "]*$")
end
to mtxrun.lua, right below the line
package.loaded["data-ini"] = package.loaded["data-ini"] or true
but this is obviously not a very good fix.
There are some threads with more details at:
https://tug.org/pipermail/tex-live/2023-March/049028.html
https://gitlab.com/islandoftex/images/texlive/-/issues/30
Those links only discuss TL, but I get the same issue if I make a symlink
to the standalone ConTeXt files.
Thanks,
-- Max

Re: [NTG-context] Credit in DTK
Hi Hraban, Wir könnten versuchen, weiter in Richtung Kirgisisch oder Georgisch zu gehen (eine Sprache, die für mich so obskur ist wie Aramäisch), nur um zu zeigen, dass Fragen der Silbentrennung nicht nur von Indianisten oder hellenistischen Experten ernst genommen werden, sondern von denen, die ConTeXt verwenden wollen . Dieser junge Ingenieur, der an seiner Statistik-Diplomarbeit arbeiten muss, ist ein Sinnbild: ConTeXt ist für die unterschiedlichsten Menschen attraktiv. Das Werk von Garulfo (ein Beispiel unter vielen) hat dies einst hervorragend demonstriert. Meine Idee war, keine mehrsprachige Antwort zu machen, sondern eine MWE mit ConTeXt in mehreren verschiedenen Sprachen (immer noch unter der Überschrift Paralleltext mit mehreren Klassenstufen), aber ConTeXt beschwert sich ... We could try to go further towards Kyrgyz or Georgian (a language which is as obscure to me as Aramaic), just to show that questions of hyphenation are taken seriously not only by Indianists, or Hellenist experts , but by those who want to use ConTeXt. This young engineer who has to work on his statistics thesis is a symbol: ConTeXt is attractive to a wide variety of people. The work of Garulfo (one example among many others) once demonstrated this excellently. My idea was not to do a polyglot answer, but a MWE with ConTeXt in several distinct languages (still under the heading parallel text with several grade levels), but ConTeXt complains... P.S. : Ik ben vergeten Nederlands toe te voegen. Ik hoop dat Hans en Taco het me niet kwalijk nemen.

I think that LaTeX extracted some parts out of ConTeXt for use with LuaTeX only
for font loading, and that is why I have it, not remembering the details. I
think I saw that LuaTeX a few years had more font loading stuff, but that was
moved to ConTeXt, but you show know better, as it would then would have been
you did it. :-)

It is line 97-105 in
/usr/local/texlive/2021/texmf-dist/tex/generic/context/luatex/luatex-math.tex
I have not done anything to that part, just adding some support for the STIX
font.

I may have not used it right, just copying it in right above line 97.

Re: [NTG-context] outputting components in their own PDFs
What exactly do you need? You can just process each component on its own. With
a makefile or shell script, batch file, that should be easy enough.
Or, do you need to have correct cross references, page numbers, etc.? I was
asking a similar question two days ago, and Hans showed me how to add
information to the log file:
\writestatus{!}{SPLIT HERE: \the\realpageno}
You should be then able to extract the split points from the log file and
extract the components from the complete PDF.
Or, if you know that you will need to split your document at certain structure
elements (chapters, sections or so), it's even simpler.
The lua script below will split your PDF at each chapter. It uses pdftk for
splitting, but it should be easy to adapt this to context's own mechanism
mentioned by Hans in the other thread.

Re: [NTG-context] Disappearing characters with nolig-german-wordlist
Arg, it's getting uglier...
I've been playing around with the replacement patterns.
```
\replaceword[replace][auff][au{ff}]
\replaceword[replace][Aufl][Au{fl}]
\replaceword[replace][aufl][au{fl}]
\setreplacements[replace]
\starttext
auffasste
auffasse
Auflage
aufliegen
auffliegen
\stoptext
```
Now it's fine for the auffasste case, but both "aufliegen" and
"auffliegen" result in "aufliegen", i.e. the second f is being swallowed.

Uncommenting one of the \replacewords makes the wrong replacement

Until TeX Live 2018, MetaFun worked in plain (at least the subset I'm
using). It would be a shame if the support would end. I also think
that there are quite a number of users. The number of posts on TeX
Stack Exchange mentioning luamplib with metafun is not negligible.
https://tex.stackexchange.com/search?q=mplibsetformat
I (and probably a lot of other people) would really appreciate if you
could apply Luigi's fix, so we can continue do enjoy MetaFun, even
outside ConTeXt.

in mp-mlib.mpiv it seems that we should have
string LUATEXFUNCTIONALITY ; LUATEXFUNCTIONALITY :=
runscript("mp.print(LUATEXFUNCTIONALITY)") ;
instead of
numeric LUATEXFUNCTIONALITY ; LUATEXFUNCTIONALITY :=
runscript("mp.print(LUATEXFUNCTIONALITY)") ;
Now I have
tex/texmf-context/metapost/context/base/mpiv$ grep -r LUATEXFUNCTIONALITY
mp-mlib.mpiv:%numeric LUATEXFUNCTIONALITY ; LUATEXFUNCTIONALITY :=
runscript("mp.print(LUATEXFUNCTIONALITY)") ;
mp-mlib.mpiv:string LUATEXFUNCTIONALITY ; LUATEXFUNCTIONALITY :=
runscript("mp.print(LUATEXFUNCTIONALITY)") ;
and your example looks ok.

hm, that can be
mp.print(LUATEXFUNCTIONALITY or 0)
but ... i'm surprised you can use metafun in plain at all ... i never
test that and to be honest am not too motivated to support mpiv code in
generic either .. better use
\startMPpage
\stopMPpage
with context and then include the pdf

Re: [NTG-context] xml in lua advice ?
My 2 cents:
local xmlflush = lxml.flush
local function text_or_xml(...)
for i,v in ipairs(arg) do
if "table" == type(v) then
xmlflush(v)
else
context(v)
end
end
end
function xml.functions.heading(t)
text_or_xml( "\\section{" , t , "}" )
end

Hans,
That works for the over-simplified case here, but fails in practice.
For a \startnarrower[left] paragraph, the mark is still in the main
margin, not the 'margin' of the narrowed paragraph. Also, the
placement of the text in the margin is wrong and not easily controlled
as with \llap and \rlap. The code started out more like:
\define\Mark{\color[middlegray]{\hskip.6cm\itb¿\ }}
\setwidthof{\Mark}\to\MarkWidth
...
\starttexdefinition stopBufTest
\startluacode
buffers.prepend("TestBuffer","\\dontleavehmode\\llap{\\Mark}")
\stopluacode
\setupnarrower[left=\MarkWidth]
\startnarrower[left,right]
\startparagraph
\inlinebuffer[TestBuffer]
\stopparagraph
\stopnarrower
\egroup
\stoptexdefinition
So I am still looking for a way to do this. Meanwhile I am trying to
understand Aditya's examples.
Turns out another answer was hidden in Hans's reply. The following seems
to meet my needs, but it may complicate other use of
\setupparagraphintro (which I don't recall seeing before), so it may not
be a generic solution.
An empty string works fine instead of the llaped marking shown here.
This is a less dangerous hack than redefining \par, but still may fail
in more complex documents when \setupparagraphintro is used elsewhere.
\starttexdefinition stopBufTest
\startnarrower[left,right]
\startparagraph
\setupparagraphintro[first][\llap{\Mark}]
\inlinebuffer[TestBuffer] \ (first: \First, arg: \Arg)
\stopparagraph
\stopnarrower
\egroup
\stoptexdefinition
Thank you, Hans.
(For a non-hack generic solution that does not interfere with other use
of \setupparagraphintro, surely there must be an easy way to apply
string.strip to the buffer.)

Perhaps \ignorespaces might work, but I often find that the conceptually
simplest solution is to post-process the buffer at the lua end. See
http://wiki.contextgarden.net/Programming_in_LuaTeX#Manipulating_verbatim_text
for an example.

[NTG-context] How can I remove a blank leading line from a buffer
%% How can one remove blank lines at the start of a buffer so that
%% commands that grab a buffer can be used in the same way as, for
%% example, \startparagraph...\stopparagraph, which allow blank
%% lines around the content?
%%
%% The problem appears when an optional argument is allowed but none
%% is provided. Adding \relax does not help; adding empty brackets
%% does. I see no way to distinguish between a buffer without
%% leading blank lines and a buffer that was created when brackets
%% are provided.
%%
%% \inlinebuffer handles the leading blank lines when there is
%% nothing prepended, but I need to prepend. (It also handles the
%% unwanted trailing line, but that is not an issue here).
%%
%% How can I unpack the buffer, apply the equivalent functions of
%% ignorespaspaces and removeunwantedspaces to it, and repack it?
%% The buffer may contain internal blank lines and macros, and
%% those should be retained. Or, is there already a function to
%% strip a buffer in the manner that string.strip does a string?

I actually already wrote parts of my invoicing solution in Lua. I was planning to even run a simple GUI (tekui) on top of LuaTeX, but my priorities keep shifting... At the moment I got shell scripts that call Python scripts that read JSON files (as a simple database) and write ConTeXt code that includes (object oriented) Lua libraries for most of the the calculations... It works well enough for my own company and our publishing house, but is quite convoluted.

I’ll try as soon as I get some time, since algorithmic image placement is a

I thought about providing a module, but each of my projects has so differing
needs that either every macro would need a bunch of options, or I need a lot of
similar macros. We’ll see...
my experience in these situations:
I'm usually implementing complicated solutions via Lua, with functions with
obligatory arg(s) first followed by one optional argument of table type:
- it's easy to investigate this optional argument and alter the algorithm
depending on table keys (presence and/or value),
- you don't have to be afraid of optional arg(s) rearrangement.
To be more concrete:
Sample Lua code
MyPlaceFigure = function(figname,
opts) -- Optional; .scale = .sc, .rotation = .rot,
.label, ...
opts = opts or {} -- To simplify code bellow
local scale, rot, lab =
opts.scale or opts.sc, -- I.e. more keys are allowed in long/short
alternative
opts.rotation or opts.rotate or opts.rot, -- dtto
opts.label or opts.lab,
nil
if label then
-- E.g. use context.placefloat(...)
else
context.externalfigure({figname}, {scale = 1000 * scale, orientation = rot,
})
end
end
Best regards,
Lukas

Re: [NTG-context] How to use "fontsampler example" with Persian font
Dear Mohammad,
Hi,
Thank you very much for your reply. I forgot to mention that I had
modified the fontsampler codes so that I can use it in ConTeXt with
Dabeer module.
However, inspired by your reply I could get it to work in LuaTeX but
not in ConTeXt with Dabeer module.
Are there any other set of features that I can test?
Thanks,
Mingranina

I don't know much about fontsampler but the commands you list here are
mostly irrelevant. My guess is you will need to set the features in the
font to get proper shaping. A good set of features that should do the
trick is called "arabic".
When loading the font, you should do something like the following, but I
have not tried it myself.

[NTG-context] How to use "fontsampler example" with Persian font
Dear All,
Hello,
I am trying to use "fontsampler example" with Persian fonts (please
see below or "http://wiki.luatex.org/index.php/Fontsampler;
for fontsampler codes).
The problem is that Persian words apears as a string of separate
glyphs, for example I get "حسن" instead of "حسن".
Do I have to use commands like the followings inside \directlua or
tex.tprint to fix the problem? If yes, how can I do that?
\installlanguage [fa][default=pe,date=\longjalalidatefmt]
\mainlanguage[fa]
\definefontfeature[tlig][tlig=yes]
\definefontfeature[slanted][slant=.2]
\definefontfeature[dlang][language=dflt]
\definefontfeature[flang][language=far]
Thanks

Re: [NTG-context] lua tables - how do you cope?
Hello Thomas,
here is my "dump()" I've been using for several years:
function dump(arg, opts) -- .seen, .pfx
if type(opts) == "string" then print(opts); opts = nil
elseif opts == true then print("-- (dump)"); opts = nil
end
local pfx = opts and opts.pfx
local seen = opts and opts.seen or {}
if type(arg) == "table" then
if pfx then pfx = pfx .. "]["
else
pfx = "["
--seen = {}
end
seen[arg] = tostring(arg) --true
local keys = {}
do
-- Sort keys, if all are strings
local strs_only = true
for k in pairs(arg) do
if strs_only and type(k) ~= "string" then strs_only = false end
keys[#keys + 1] = k
end
if strs_only then table.sort(keys) end
end
for _, key in ipairs(keys) do
local val = arg[key]
io.write(pfx .. tostring(key) .. "] = " .. tostring(val) .. "\t(" ..
type(val) .. ")")
if type(val) == "table" then
if seen[val] then print(" (seen)")
else
print()
dump(val, {pfx = pfx .. tostring(key), seen = seen}) --pfx ..
tostring(key), seen)
end
else
print()
end
end
else
print(arg)
end
end
Try:
a = {c = 1, b = 2}; a.a = a
dump(a)
dump(a, "This is 'a'.")
Improvements or parametrization of visualizing style would be possible, of
course...
Best regards,
Lukas

[NTG-context] tagging a startstop
Dear syndicate,
We have \definehighlight[tagged][style=] so that
\tagged{arg}
tags the argument. Analogously: Is there a general facility to tag
startstops? I played around with \dostarttagged etc but could not get it
to work (too low-level for me I guess). What would be nice is to be able
to say, e.g.
\definestartstop[TAG][tag=div] % or tag=construct etc.
so that my startstop also generates tags in the xhtml. Is there already a
way to do this?
Thanks and Best Wishes

[NTG-context] total pages in external PDF
Dear list,
I need to get the number of pages from an external PDF file that I also
define with an \env.
I think I could get something like this.:
\def\Myfilename{\env{filename}}
doc = epdf.open(arg[\MyFilename])
total_pages_ = doc:getNumPages()
\def\Mypages{total_pages}
But mixing both lua and ConTeXt commands the wrong way won’t work.
Sorry, but this is all Greek to me. Although I see how it could be done,
I cannot write the code for this.
Which is the right way to get the code above working?
Many thanks for your help,
Pablo

You can’t do this form a definition for a verbatim command because TeX has its
own rules
for such a situation (search for a description about catcodes), when you want a
copy of
\TeXcode add
\definetype[arg][TeXcode]

Is there no way that I have the already predefined \arg with colored
contents (braces included)?
Even with defining another command, the problem is that left and right
aren’t covered by option=TEX.

\defineregister[Erf][Erflist]
\defineregister[Erf]
It doesn’t appear to be documented anywhere (even the source ...)
but in mkiv \defineregister is an ordinary command handler so no

I've added \mult_check_for_parent so at least there is less change for a
crash but a complete auto parent define is never going to work so it's
reported as error:
system error: invalid parent Erfs for Erf, Erfs defined too (best

Untested:

CM Unicode has a good coverage of greek characters in typewriter font.

Since no one has offered a quick ConTeXt solution, I offer my usual -- a

\def\lomihi#1#2#3{${\scriptstyle{#2}}\limits_{#1}^{#3}$}
With the Computer Modern font, the top is a little further away from the
middle than the bottom. It can be adjusted with something like
\def\lomihi#1#2#3{${\scriptstyle{#2}}\limits_{#1}^{\lower0.23pt\hbox{$\scriptstyle{#3}$}}$}
but this would probably have to be adjusted for each font and size.
You can use \framed:

\definehigh [MyHigh] [style=\txx]

So, we have low/high definable and clonable etc. Best check if the defaults

ok, i'll fix that ... (or maybe midlowhigh is nicer ?)

only with low, high an lohi
up = how much the {hi} arg is raised
down = how much the {low} arg is lowered
indeed
Support for the [left] keyword seems to have been dropped, but is

still there, only for lohi .. maybe we should add an align key some day

hm, distance is often used for this so that's better
I'll do 'align' when there is demand for it.

[NTG-context] nesting commands with optional arguments
Dear list,
I have a question concerning nesting commands with optional arguments.
I'm trying to put a command with an optional argument inside the
optional argument of another one … For sure this is just a simple
expansion problem but I have no clue how to handle this …
Thanks for any hints!
Daniel
Please consider the following minimal example:
\def\one{\dosingleempty\doOne}
\def\doOne[#1]{%
in 1st: \doifsomethingelse{#1}{#1}{no arg}\par%
}
\def\two{\dosingleempty\doTwo}
\def\doTwo[#1]{%
in 2nd: \doifsomethingelse{#1}{#1}{no arg}\par%
}
\def\three#1{in 3rd: #1\par}
\starttext
\one\two
\blank
\one[\three{myArg}]
\blank
\one[\two[Argument]]
\stoptext
This is what I get:
! Use of \doOne doesn't match its definition.

Tables are references. Using the “local” keyword, you generate a
local variable that still points to the original table. Instead,
you need to (deep) copy the table explicitly.

Hans, all,
I attach a document (source and PDF) with some \unit test cases that don't
currently work
(even with the most recent beta). It also has a number of suggestions for
improvement.
Some of this should be construed as personal opinion, but hopefully it isn't
too controversial.
Nice summary, you should write a My Way about units once this things are fixed.
A few comments from me:
\type{1234}\tex{unit}\arg{m} should print equivalently to
\tex{unit}\arg{1234m}
and \tex{unit}\arg{1234 m}. (I have a lot of text that uses a \tex{unit}
macro like that.)
Maybe it’s possible with MkIV to check if the text before the \unit command was
a number but of the number is part of the unit them put in the command, such
things are always tricky with TeX and it’s better to force users to use proper
input.
Within \type{phys-dim.lua} all the units and all the prefixes seem to have
capitalised names; in fact, they should be all lowercase (even when they
are named after some person). The exception is Celsius.
I think this is a feature because Hans saves also a lowercase version of all
keywords and you can use both as input.
I wonder whether \tex{unit} should only parse and format units, and have
another macro \tex{quan} or \tex{quantity} to handle number+unit
combinations
(obviously using \tex{digit} and \tex{unit}).
Please don’t suggest this, one of the nice features is that you don’t have
to care which command you need but it would be nice to drop the old
formatting options for \digits in the \unit command.

[NTG-context] Finding values of the context macros inside Lua functions (=expansion inside Lua functions?)

My minimal example (I mention it at the end of email) for clear reasons

7 is number.
7is not number.
7is not number.
In the first is argument '\value' negotiable to the value, in second it
is not possible (but for clear reasons too).
I would need to find from argument ie macro '\\value' in the LUA
function its numerical value.
Is there any function that would do that?
I need something as a function of context (...), which would, however,
its output is not located into ConTeXt, but its result get to back to a
Lua function or into variable.
It is something like the expansion of an existing ConTeXt macro to its
value.
Thanx Jaroslav
Here is my minimal example:
\startluacode
function test(arg)
if type(arg)=='number' then
context(arg.. is number.\\par )
else
context(arg.. is not number.\\par)
end
if type(tonumber(arg))=='number' then
context(arg.. is number.\\par )
else
context(arg.. is not number.\\par)
end
end
\stopluacode

Re: [NTG-context] Finding values of the context macros inside Lua functions (=expansion inside Lua functions?)
Thanx Wolfgang.
But I guess I was wrong to express..
I need to pass parameter '\\macroI' to the function and turn it up a
inside luafunction expand to its value.
Ie when \def\macroI{6}
Then I need when I make in your example \ctxlua{test(\\macroI)} get
the result :
The argument “6” is a positive number and not result The argument “6”
is a string.
see: I modify your example :
\startluacode
function test(arg) -- use thirddata namespace for real functions
if type(tonumber(arg)) == number then
if tonumber(arg) 0 then
context(The argument \\quotation{%s} is a positive
number,arg)
else
context(The argument \\quotation{%s} is a negative
number,arg)
end
else
context(The argument \\quotation{%s} is a string.,arg)
end
end
\stopluacode
\starttext
\ctxlua{test(7)}
\ctxlua{test(-4)}
\ctxlua{test(text)}
\def\macroI{6}
\ctxlua{test(\macroI)}
\ctxlua{test(\\macroI)}

Re: [NTG-context] [beta] grid head
Hi Hans,
the new beta appears to modify the behaviour of long headings on
the grid. In the following example the chapter head moves up into
the page header which it did not prior to the update (cf. mkii’s
behaviour):
·
\setuppapersize[A5][A5]
\setuplayout[grid=verystrict]
\setupheadertexts[{Blindtext}][{\tfb\bf \pagenumber}]
\setuphead[chapter][
style=\WORD,
grid=yes,
]
\starttext
\chapter
{This is supposed to mimick a rather long chapter title as is
common in German language environments; shorter titles might not
look as natural as longer ones}
\dorecurse{5}{\input dawkins\par}
\stoptext \endinput
·
Gridless it works ok. I’d just like to know whether this is to be
taken as a bug or as a feature. Thanks a lot,

Hi Hans,
my xml files seem to run OK (I just did a few experiments). However,
there is a problem with the new project structure code. My book project
is set up like a proper ConTeXt project, and with the new version,
context has lost the ability to compile single components.
context mycomponent
will compile the entire document, and then append the single mycomponent
at the end of the document. That can't be right...

Re: [NTG-context] Optimal way to defining of macros in Luacode in ConTeXt
Thanx very much Hans and Wolfgang too,
I converted ALL my ConTeXt definitions (macros) with fixed numbers of
parameters by using yours method - ie:
interfaces.definecommand {
name = ,
macro = .,
arguments = {
{ content, string },
{ content, string },
},
}
It is great and very easy - thanx.
Now I want convert rest of definitions (macros) - they have varied
numbers of parameters.
Is there any similar way to do it? Suffice it to indicate how.
Thanx Jaroslav
To show what macros I want to convert, I mention these examples:
\def\opencsvfile{%
\dosingleempty\doopencsvfile%
}
\def\doopencsvfile[#1]{%
\dosinglegroupempty\dodoopencsvfile
}
\def\dodoopencsvfile#1{%
\iffirstargument
\ctxlua{thirddata.scancsv.opencsvfile(#1)}
\else
\ctxlua{thirddata.scancsv.opencsvfile()}
\fi
}
or other macro etc:
% \doloopaction % implicit use \lineaction macro
% \doloopaction{\action} % use \action macro for all lines
% \doloopaction{\action}{4} % use \action macro for first 4 lines
% \doloopaction{\action}{2}{5} % use \action macro for lines from 2 to 5
\def\doloopaction{\dotriplegroupempty\doloopAction}
\def\doloopAction#1#2#3{%
\opencsvfile%
\doifsomethingelse{#3}{%3 args.
\doloopfromto{#2}{#3}{#1}% if 3 arguments then do #1 macro from #2
line to #3 line
}{%
\doifsomethingelse{#2}{%2 args.
\doloopfromto{1}{#2}{#1}% if 2 arguments then do #1 macro for first
#2 lines
}%
{\doifsomethingelse{#1}{% 1 arg.
\doloopfromto{-1}{-1}{#1}%
}{% if without arguments then do \lineaction macro for all lines
\doloopfromto{-1}{-1}{\lineaction}%
}%
}%
}%

It depends what you want to achieve, while you try to create many commands
in the form \MacroXXX where each command contains some content i define
only one command which takes the content only when requested.
When I will return to the subject of this mail:
Can also be used for the council said Hans macros with multiple parameters?
For example macros without parameter is no problem:
context.setvalue('printline',calling.luafunction(),tex.par)
I assume that for a more parameters cannot be used context.setvalue (...) ..
But how to use multiple parameters when defining the macro as follows:
context([[\\def\\paramcontrol#1#2{%s}]],thirddata.scancsv.paramcontrol('#1',
'#2'))
Look into cldf-int.lua where you can see a method to create TeX commands
without optional arguments from Lua.

Re: [NTG-context] Optimal way to defining of macros in Luacode in ConTeXt
Hello all.
It is GREAT! Thanx Hans and Wolfgang too. It is very instructive and
inspiring for me...
I was looking for something similar for a long time, but I have not
found anything (not even in the CLD-MKIV and others ...). Finally, after
yours reply to this email find something in the ctx-man.pdf from 1997
year :-).
But I have a few questions and comments on this subject:
1. Is there any possibility to do anything similar with counters,
dimensions etc? I trying but without success.
For example:
context.newcount(mycounter) or context.newcounter(mycounter)
context.mycounter=5 etc.
or it must be realized by classical way:
context('\\newcount\\mycounter')
context('\\mycounter=10')
context('\\advance\\mycounter by5')
context('\\the\\mycounter')
similary with \newdimen, \newif etc...
2. Any person interested in using context.setvalue{Mymacro,somevalue)
and context([[\def\MyMacro#1{#1}]]) syntaxes I have pointed out that the
second syntax only operates when the command is given in a separate LUA
file (ie file.lua) (ie not within an environment \startluacode -
\stopluacode in classical TEX file!!!). Hans told me once that it is the
individual categories of characters (backslash??) (if I remember correctly).
First syntax works perfectly in LUA and TeX files too.
Here I have a question. Why not comment out this case in TEX file?
\startluacode
-- context([[\def\macro#1{#1}]])
\stopluacode
I get error:
! Undefined control sequence.
-- context([[\def \macro
#1{#1}]])
\dodostartluacode ...and \directlua \zerocount {#1
}}
l.25 \stopluacode
?
That category characters again? Comment character -- works differently
in TEX file, and otherwise in the LUA file?
Ie. comment on the backslash?
3. Wolfgang write about using context command
\convertnumber{R}{1400} and the corresponding syntax:
context.convertnumber(R,1400) to roman converting.
It is great, but I could not figure out how to use in combination with
the above syntax (ie use case context.command) or find the appropriate
conversion LUA function (I did not use a custom function).
Is there any way to do something like that:
context([[\def\Macro%s{Macro%s}]],context.convertnumber(R,1400),1400) ???
ie. TEX command is used as a LuaTeX parameter?

When more than one argument is given, the context command treats the

[NTG-context] Optimal way to defining of macros in Luacode in ConTeXt
Hello ConTeXist.
How best (optimally) in Lua code in ConTeXt define own ConTeXt macros?
I was used recently LuaTeX syntax (for example) :
tex.sprint(tex.ctxcatcodes,'\\def\\mymacro\{arg of mymacro\}')
But someone advised me that I use the better syntax:
context('\\def\\Mymacro\{arg of mymacro\}')
or context(\\def\\test#1{#1}) etc...
Exist other (best or most optimal) way to do?
for example something like:
context.def.mymacro(first arg, sec arg:) (which of course does not
work ...)
Thanx Jaroslav
My example:
\startluacode
function ar2rom(arnum) -- Convert Arabic numbers to Roman. Used for
numbering column in the TeX macros
local romans = {{1000, M},
{900, CM}, {500, D}, {400, CD}, {100, C},
{90, XC}, {50, L}, {40, XL}, {10, X},
{9, IX}, {5, V}, {4, IV}, {1, I} }
local romnum=''
for _, v in ipairs(romans) do -- create of the Roman numbers
val, let = unpack(v)
while arnum = val do
arnum = arnum - val
romnum=romnum..let
end
end
return romnum
end
for i = 1, 10 do
tex.sprint(tex.ctxcatcodes,'\\def\\macro'..ar2rom(i)..'\{macro
'..i..'\}')
context('\\def\\Macro'..ar2rom(i)..'\{Macro '..i..'\}')
end
tex.sprint(tex.ctxcatcodes,'\\def\\mymacro\{arg of mymacro\}')
context('\\def\\Mymacro\{arg of Mymacro\}')
\stopluacode
\starttext
\macroI, \MacroI
\macroII, \MacroII
etc ...
\macroIX, \MacroIX
\macroX, \MacroX
\Mymacro, \mymacro

You can use “context.setvalue”. To convert numbers in different formats
you can use the \convertnumber command.
\starttext
\startluacode
context.setvalue(One,1)
context.setvalue(Two,2)
\stopluacode
\define\Three{3}
\One:\Two:\Three
