If so then I suggest that you create a new Linux user and try installing under 
that new user. If it works then it's something in your user account. If it 
fails then ... well, we're no worse off. :-)

Then something is not making sense (to me).

.bashrc clearly shows: export 
PATH=$PATH:/home/me/bin/context/tex/texmf-linux-64/bin, so does that not mean 
that bin can be found via the path? So why does 'context myfile.tex' not work?

If I run a full path (. /home/me/bin/context/tex/texmf-linux-64/bin/mtxrun 
context myfile.tex) I get the message 'cannot execute binary file' and yet 
mtxrun is executable. I checked. Clearly I am making a basic error, but cannot 
work out what.

Thanks. I guess, it is time to freeze the mkiv version of the module and 
introduce a mkxl version.

So this is not lmtx (which also has luatex) but the regular installation 
right?


Does that file have \starttext ... \stoptext ?

There is something missing:

   ..cont-en.lui cont-yes.mkiv --c:currentrun=1

in mkiv the input is loaded indirectly (via cont-yes.mkiv) but in lmtx 
we don't pass that one (not needed as we start up a bit different)

Thank you a lot for the explanation! It makes more sense now and
definitively is something very promising to play with. Wrt the module
itself, is it possible to consider language-dependent labels? I noticed
"\sin" is "sin" when it should be "sen" once the module is loaded.

and yes, \integerdef is also a primitive (doesn't waste a register)

in order to implement 'new primitives' using lua (like some that need to 
be implemented for compatibility reasons due to the backend differences) 
we need to be able to distinguish between setting and getting a value

a good example is the extended macro argument handling: less clumsy tex

tracing, but it violates the last argument because it did lead to some

macro definitions and expansion)



I did the following and I have two questions:

1. What if I want to have more than one property? Say \plusone for 
computation and \plustwo for drawing.


you can do that but keep in mind that \compute is then an 'official' 
context one (bound to 1) and any other number can conflict with other 
context numbers in the future, so best start at 1000 or so for private 
ones


2. What does 'usage="value"' mean in the implement function (looks new, 
but I'm prolly wrong)?


indeed, it is already there for a while and it lets the function 
definition follow a different route ... basically one that can follow 
\the; I suppose that I can also make 'property' a valid usage (alias)


(btw often features like this are described in articles or wrapups inm 
documents in the distribution or even mentioned here but as usual with 
tex these things only make sense trigger usage when one really needs it)



\permanent\protected\def\drawme{\thewithproperty\plussix} %better than 666


or 31415 to fit in the tex numbering


\startluacode
local interfaces = interfaces
local implement = interfaces.implement
local context = context
local drawme_code = 6
local drawing = [==[
draw fullcircle scaled 10mm;
draw fullcircle shifted up scaled 5mm;
draw fulltriangle shifted (up+1/2right) scaled 5mm;
]==]


local function chicken(value)
if value == "value" or value == drawme_code then


no need to check for "value" unless you also want:

\the\chicken


context.metafun.start()
context.metafun(drawing);
context.metafun.stop()
--elseif then ...
else
context("Chicken!")
end
end

implement{
name = "chicken",
public = true,
usage = "value", --What does it do?
overload = true,
actions = chicken
}

\stopluacode

\starttext\chicken\ and \drawme\chicken\stoptext
indeed an example of usage, and as with the mathfun, it saves a ton of 
macros like \drawchicken and so


so now you next challenge is to pass arguments so here a next phase

[NTG-context] Unwanted upright math in MkIV

2021-05-23 Thread Gavin

Hello,

I’m using ConTeXt with MacOS. The current version of MkIV produces upright math 
rather than italic. MWE:

\starttext
\m{f = \beta}
\stoptext

The above example produces italic math TeXLive 2021 ConTeXt and in the current, 
LMTX. Looks like a bug to me, but maybe I am doing something wrong. I am 
running ConTeXt from TexShop using this engine:

#!/bin/zsh
export PATH=/Users/Gavin/context-osx-64/tex/texmf-osx-64/bin:$PATH
~/context-osx-64/tex/texmf-osx-64/bin/context --luatex --autopdf "$1”

Re: [NTG-context] Special layouts don't recognise placeinitial

My question will be very simple: Is there a trick to make \placeinitial 
command work within makeup pages?


One of my pages inside the /frontmater/ is a quote page within an 
special layout. Before using LMTX, when I could use the Lettrine module, 
that quote started with a capital letter. But now that I use 
\placeinitial, the first letter no longer changes: it remains a simple 
initial capital letter.
On the other hand, when I use \placeinitial for each first paragraph in 
the chapters of my book, the result is as expected. That is, the command 
works fine as long as it stays within the general layout.

This is the code I'm referring to:

\startmakeup[standard][doublesided=yes]

\setuplayout[backspace=176pt,width=194pt]
\setupinterlinespace[line=22pt]
\style[tfa]

\startalignment[hanging,flushleft,nothyphenated]

a  su  dama  diariamente,  pero  está  encerrado para  siempre,  o  el  
que  es  libre  de  ir  donde  le  plazca, pero  no  verá  nunca  más  
a  su  dama?  Aquellos  de  vosotros que  podáis,  elegid  entre  las

empezado.

\stopalignment

\startalignment[hanging,flushright,nothyphenated]
\blank[0.8cm,force]{\tfa\sc  Geofrey Chaucer,\hspace[big]}
\blank[0.1cm,force]{\tfa\em The Canterbury Tales \hspace[big]}
\stopalignment

\stopmakeup

You can add this to cont-new.mkxl (assuming lmtx)

\unprotect

\permanent\tolerant\protected\def\flushinitial
  {\typo_initial_handle}

\protect

and then

\placeinitial  \flushinitial Ahora, ...

will work. More clever automated solutions are likely to interfere and 
have side effects for embedded cases so this is the best I can come up 
with now.

to serialize the dimension in cm but normally i need to "wonder for a 
while if it makes sense".


Btw, adding primitives (related to the token related bits and pieces of 
the engine) only makes sense if the gain is in


-- avoiding clumsy code: although that can hurt someones pride and joy 
over a nice and complex macro doing the same ... don't worry, i threw 
away plenty of code by now


-- significant performance gain: which is seldom the case (there really 
is not much to gain, at least not in context which is rather optimized 
already)


-- giving way less noise in tracing: which for me is a good reason 
(tracing changed a bit anyway)


-- not adding much code to the engine or the need to refactor: although 
for some luametatex extensions some internals had to change fundamentally


a good example is the extended macro argument handling: less clumsy tex 
code, a bit of performance gain and easier full expansion, way less 
tracing, but it violates the last argument because it did lead to some 
refactoring (i also had to make sure the extra overhead didn't slow down 
macro definitions and expansion)

Re: [NTG-context] LMTX install

2021-05-23 Thread jbf

Linux Mint 21 and yes, followed precisely the instructions on the wiki 
page. mtxrun is executable. Not sure why this has to be so difficult but 
it is not working.

You don't say which Linux you are using so I would first check to see that
  /home/me/bin/context/tex/texmf-linux-64/bin/mtxrun
is executable.

I assume that you followed the instructions on the wiki page here?

Re: [NTG-context] LMTX install

Not pedantic, just correct. I should have said Linux Mint 21! I'll check
the status of mtxrun but I thought all that would be automatic

[NTG-context] LMTX install

2021-05-23 Thread Benny Schurig


Hi Julian,

afaik with lmtx a setup is not necessary. With mk iv it established the 
tex tree. With lmtx the tree is somehow self-contained.


I use lmtx and point the compile command of my editor of choice (Geany, 
Kile, Texmaker, Emacs whatever) directly to 
.../context/tex/texmf-linux-64/bin/mtxrun --autogenerate --script 
context [file]


Best, Benny
