[NTG-context] Re: how to include an an svg file?

[seyal zavira]

Thanks. I appreciate your work

You are correct. when i convert this svg to pdf via inkscape it works like
a charm.

But what is standard way of including an svg file with context if we want
to inkscape render the images?

[Jean-Pierre Delange]

Yes, the code given by Seyal gives only the circle vith eyes and mouth 
without colors (on my computer). But, It seems that one have to deal 
with a more complex lines of code. If I'm not mistaken, MetaPost alone 
natively supports only the 3 colours red, green and blue. To support 
CMYK colour gradients, MetaPost needs to work with Metafun (see here : 
https://wiki.contextgarden.net/Color_in_MetaPost).


Perhaps an image in *.png format is required. But I can't give any 
advice, as I'm not an experienced MetaPost/Metafun user.


see this code below and the result as attached file :

\starttext

\input tufte


\externalfigure[smile.svg][conversion=mp]

\stoptext

but i need to discuss it with Mikael as we might integrate something

Hi Andrés,

this looks interesting (even if I don’t do calligraphy any more).

Sorry, I can’t help you with your questions.

The structure of the module looks good and should work well with the

[NTG-context] Creating a module for calligraphy practice templates

[Andres Conrado Montoya]

Hello, list!

I've been working on a module to typeset calligraphy practice templates
using ConTeXt and MetaPost. You are welcome to check it out on github:
https://github.com/conradolandia/pauta
I'm not including a MWE because the repository has all the current code. I
hope this is fine. I did not want to clutter the list with too much text.
The module is only a single file (t-pauta.mkxl) and some examples of use
and documentation that are still somewhat unfinished, but I've tried to
document the source code as much as I could. If you need clarification
about anything, please let me know.

(At the root of the repository, there is a file build.lua, that is not
really part of the project, just a custom tool I use to process the files,
a sort of minimal build system. You can ignore it.)

I welcome any kind of suggestions and dire warnings. I've tried to read the
wiki and the manuals carefully and made as many tests as possible, and in
general it works fine, but I have ADHD and things frequently get over
my head. There are still some things that don't work as they should, and
things that need improvement:

1. I use top/bottom areas to display some info. These areas are not being
handled properly so far. For example, if I place a chapter before the Pauta
macro invocation, there will be data on the top and bottom areas in the
last page of the chapter. I've tried using \page and clearing the areas,
which feels like cheating, but still does not work well. Any ideas on how
to better handle this are more than welcome.

2. I'm using what I found at
https://wiki.contextgarden.net/System_Macros/Handling_Arguments and
\getparameters to handle the arguments for my Pauta macro, but today I
found out about \processaction at
https://wiki.contextgarden.net/Module_Parameters and I'm not really sure if
I should change my module to work with this instead of \getparameters. In
general, after checking the source code of several modules, I'm not really
sure how much I have to follow the guidelines at
https://wiki.contextgarden.net/Module_Parameters or if those are the most
current recommendations.

3. I'm including in my module the code of the file hatching.mp that can be
found at
https://ctan.org/tex-archive/graphics/metapost/contrib/macros/hatching. I
did this for portability reasons, since it's less than 70 lines and has not
been updated in 20 years. But if it's better to have this in a separate
file, please let me know. Also, if a better method to create pattern filled
paths is available, please let me know, I confess I didn't look too much
into it yet. This has solved my requirement so far.

4. I want to be as close as possible to the new LMTX syntax and way of
doing things. so If you think I'm doing something in anachronistic ways,
please let me know.

In general, if someone wants to check it out and provide feedback so I can
improve it, with the objective of eventually being shared on
modules.contextgarden.net, will be much appreciated.

Thank you for your time, and have a great week!

[NTG-context] \intertext and highlighting with \alignhere/\breakhere

Hi all,

Often I want to include a sentence/paragraph in the middle of a long
multipart formula. With the old \startalign/\stopalign formulas, I could
use \intertext{...} to do this, but this doesn't work with the new
\alignhere/\breakhere formulas. I've managed to find a "solution" for
this, although I'd prefer something a bit less hacky. Any ideas?

Also, is there a way to highlight an equation across an \alignhere? Once
