[NTG-context] Re: wiki update: Modules

[Andres Conrado Montoya]

In the wiki, if I click a link to check a source code file (for example
https://source.contextgarden.net/tex/context/base/mkiv/m-catchword.mkiv) I
get a blank page with a very long list of source files on the left. If I
search for the file with my browser's ctrl+f on that page, it returns zero
results. I'm using Chrome. It happens for every link to source files.

Not sure if it's a problem with my setup, but I have noticed that
before, in different machines. Can anybody else confirm if they can
correctly see the source files when clicking the links?

[NTG-context] Re: wiki update: Modules

[Jeong Dal via ntg-context]

Dear Hraban,

When I wrote a class material for Linear Algebra, it is nice to use \pmatrix 
and \bmatrix etc. 
But, for example, to write a result matrix of the product of two matrices, I 
need to calculate it somewhere and copy it to my text. Hence, I tried to use 
Lua to handle it in the ConTeXt. And, it is nicely working.
During the process, I asked many questions to Hans and he gladly helped me.
It is the first time for me to code using Lua, so my coding was clumsy. 
However,  Hans corrected it to be usable in ConTeXt even though he is very very 
busy in many things.
And, he made it a module and put it in the list.
Thanks Hans.

Finally I finished several chapters on Linear Algebra using that code.
It was many years ago.
Here is a document of it. I confirm that it is running well without any problem.

I hope that someone who wants to write an article on Linear Algebra use it.

Thanks for reading.

Best regards,

Dalyoung

[NTG-context] Finding the position of an image on the page.

[peter.hopcroft--- via ntg-context]

Hello list,

Can I find the position of an image on the page after I have placed the image 
with \externalfigure? 

For example, the top, left corner of the image might be 50 mm in from left side 
of page and 120 mm down from the top of the page.

I know I can use \getfiguredimensions to find information about the placed  
image, but it does  not give me the position of the image.

Thank you
Peter Hopcroft

Hi Hraban,

Thank you for your updating of the modules stuff.
As far as I remember the matrix features are not related to any modules, 
but rather are part of LMTX. In nay case next week I will look at the page


https://wiki.contextgarden.net/Matrix_in_maths 



and verify that eveything on that page works fine and is up to date.


Thank you!

But there _is_ a matrix module (hey, I just looked through all this 
stuff!) by Jeong Dalyoung & Hans; apparently it can do matrix calculations.

In the wiki page you can see that there’s still some working code for 
chemistry, but it looks very broken.


ppchtex.mkiv is apparently still code from 1996 (and can’t work, since 
neither PicTeX nor PStricks are supported in LMTX any more).


chem-str.lua seems to be an updated version by Alan & Hans

Did I miss something?


work in progress ... i'm working on that (part of the math upgrade) so 
best wait till we're stable


Ok, thank you
