Re: [NTG-context] Metapost Animation of Sine

2021-07-21 Thread Otared Kavian

Hi,

Adding to my previous message, if you are looking for an animation of the wave 
equation for a string with fixed endpoints, one has to use something like the 
following:

% begin wave-sine-string.tex
\usemodule[animation]
\setupinteraction[state=start]
\starttext
\startTEXpage[offset=2pt]
\startanimation[menu=yes,framerate=10]
\dorecurse{101}{\expanded
{\startframe
\startMPcode
numeric u, omega, mylength, tt, N ;
u := 2cm ;
omega := 4 ;
mylength := 3.141596 ;
tt := \recurselevel - 1 ;
N := 500 ; % number of steps
path p ;
p := (0u,0u) for i = 1 upto N : 
-- 
(((mylength/N)*i)*u,cos(omega*(mylength/N)*tt)*sin(omega*(mylength/N)*i)*u) 
endfor ;
draw p withpen pencircle scaled .5pt withcolor darkred ;
\stopMPcode
\stopframe}
}
\stopanimation
\stopTEXpage
\stoptext
% end wave-sine-string.tex

Best regards: OK

path p ;
p := (0u,sin(omega*(mylength/100)*tt)*u) for i = 1 upto 
100 : 
.. 
(((mylength/100)*i)*u,sin(omega*(mylength/100)*(i + tt))*u)

Re: [NTG-context] Use of lettrine module in LMTX

I do not have an answer to your question, but I'd like to point out that
you can keep using lettrine with ConTeXt LMTX, if you wish. You just
need to add the modules manually, currently:

https://wiki.contextgarden.net/Modules#ConTeXt_LMTX


I’ve tried this. Installed the modules and then I get with

[...]


Short version:

You get an error message for the \!!dimena command which is used by
the module but doesn't exist anymore.


Long version:

Hans started a few years ago to replace many of the old cryptic names
(e.g. \@EAEA) with sometimes longer but more readable names
(e.g. \doubleexpandafter). A short while ago he removed a few of these
old commands (in this case a length register) in LMTX because they
aren't used anymore in the core.

The lettrine module is very old and never got a proper MkIV/LMTX
version and the use of one of these old commands results in an error.

While it's easy to fix the problem you're going to find the next problem
because LMTX has a new mechanism which is related to paragraph
related settings like indentation. As a result of this new mechanism
\lettrine places the initial to the left of the paragraph without
reserving space to indent the first few lines.

I was sure that I had used lettrine with MKIV in a document of mine, but
after your reply I double checked that and, in fact, I was using
lettrine only with MKII. On the plus side, I have recovered my settings
for MKIV (which work with LMTX as well).

I think that the `distance` parameter of \setupinitials does what you
want. Besides, if your font provides real small capitals, you may use
\definefirstline.

This is how I set up things in one of my documents:

\definefontfeature[default][default][protrusion=quality,expansion=quality,onum=no,lnum=yes]

% \definefirstline below requires a font that implements small capitals as
% a feature (Latin Modern does not). I have used this:
% \definefontfamily[mainfont][serif][Sorts Mill Goudy] [
%   tf=name:Sorts Mill Goudy Regular,
%   it=name:Sorts Mill Goudy Italic,
% ]
% If you don't have the font above, try this:
\setupbodyfont[heros]

\setupbodyfont[mainfont,11pt]

\definemeasure[CAindent][12pt]
\setupindenting[yes,\measure{CAindent}]

% Every chapter body text starts with a drop cap:
\defineinitial[normal][
  n=3,
  m=1,
  distance=18pt, % <== Add this 
  state=start
]

% Special case: drop cap starting with a quote
\defineinitial[quote][
  n=3,
  m=2,
  distance=13pt,
  hoffset=5pt, % Move drop cap a bit to the left
  method=none
]

% Some initials may need special adjustments, depending on the font
\defineinitial[Q][
  voffset=2\lineheight,
  n=3,
  m=1,
  distance=18pt,
  state=start
]

% Full first line in small caps
\definefirstline[smallcapsfirstline][
  alternative=line,
  style=smallcaps,
]

% First n words in small caps (three in this case)
\definefirstline[smallcapsfirstlinethree][
  alternative=word,
  n=3,
  style=smallcaps,
]

\starttext
\setfirstline[smallcapsfirstlinethree]
\setinitial[normal] Suppose we have a system for the approval of
loans. \input knuth
\blank[2*big]

\setfirstline[smallcapsfirstline]
\setinitial[quote] “Suppose we have a system for the approval of
loans.” \input knuth
\blank[2*big]

\setfirstline[smallcapsfirstline]
\setinitial[Q] Quo usque tandem abutere, Catilina, patientia nostra? quam diu
etiam furor iste tuus nos1 eludet? quem ad finem sese effrenata iactabit

[NTG-context] MP keyword function: string parameters no longer accept string variables directly

2021-07-21 Thread Rudd, Kevin

Hi---

Here's another apparent change on the MP side---for keyword functions, string 
parameters no longer accept string variables directly. They do seem to register 
them (hasparameter => true) but don't capture the value (getparameter => 0). 
Thus:

system  > ConTeXt  ver: 2021.07.16 22:03 LMTX  fmt: 2021.7.21  int: 
english/english

metapost> trace > This is MPLIB for LuaMetaTeX, version 3.11, running 
in scaled mode.
metapost> trace >
metapost> trace > loading metafun for lmtx, including the plain 1.004

metapost> trace > >> true
metapost> trace > >> 0
metapost> trace > >> "expression containing string variable fuschia =

metapost> trace > >> true
metapost> trace > >> "fuschia"

String constant: succeeds
String variable: fails
String expression with string variable: succeeds

Here's the MWE:



% system  > ConTeXt  ver: 2021.07.16 22:03 LMTX  fmt: 2021.7.21  int:

Here is another way to do your animation. This is doing something, but I guess 
not what you want. Could you describe what do you have in mind ?

\starttext
\dorecurse{7}{ % 3180
\startMPpage
myvariable := #1 ;
path p;
numeric n, u;
u := 1cm;
n:=myvariable*u;
p := (-90/360*1.5cm,-0.9cm) for i = -90 upto 630: .. 
(i/360*1.5cm,0.9cm*(sind(i))) endfor shifted (n,0);
draw p;
\stopMPpage
}
\stoptext

All of my figures that use MP boxes are now failing. It looks like

correct as it appears that lmtx loads "mp-xbox.mpiv" instead of

Indeed, I made that one an mp-* because it removes a dependency. The

Thanks for any suggestions,


i'll add

def boxjoin(text t) =

for now you can just add it

hm, indeed, fixed; thanks for noticing,

[NTG-context] Metapost Animation of Sine

[NTG-context] MP boxes: boxjoin not recognized?

Argh; mea culpa. Thanks for the very quick reply, Hans. It does work "as 
expected" (albeit deprecated)---Tracking down errors, I was misled by an error 
immediately following the deprecation warning and associated it with the 
warning, not the subsequent text.

This is quite readable, and much preferred to the use of any kind of

I find that students often need such helpers when deciphering many

Let's not forget all of these spaces commands are used in math mode.
Sure, and thet adaot to math mode. They will nto dissppear, it's just
