Many thanks for the new upload, Hans.

Dear Floris,

I have a simpler approach that might help you:

 curl -I http://pragma-ade.com/context/latest/cont-tmf.zip

I added a file with that to $HOME/bin/ and it works fine when invoking it.

To check which version you have installed on your computer:

export PATH=$PATH:$HOME/context/tex/texmf-linux-64/bin/ && context
--version && luametatex --version

Of course, you might need no export or adapt $PATH accordingly to your
ConTeXt directory.

Just in case it helps,

Pablo

Dear Hans,

Would it be possible to have a simple text file with the latest release 
version (or date) tag in it? Next to the folder containing the actual 
install script files? In that case it is easy to check that version tag 
by comparing with the local copy and decide if a further download and 
install is needed.

Hi Otared,

I don’t know which one, but I think the LMTX installer may have a bug
that prevents updating the installation in all platforms (at least, it
seems to be so in Windows, macOS and Linux).

I thnk that removing the tex/texmf-*.tma files, allows a new
installation. It may overwrite all files (modified or not). But it might
be that this doesn’t remove deprecated files.

> Thank you for the hint…

It was by pure chance that I discovered that this might work.

But I’m glad to see that this may help,

Pablo

Re: [NTG-context] new upload

Hi Pablo,

I had the same issue as the one you were reporting (on MacOS 10.14.6).
I removed the three files 

texmf-context.tma
texmf-osx-64.tma
texmf.tma

before issuing the command 
sh install.sh

Now I am getting 

fetching 'http://lmtx.pragma-ade.com/install-lmtx//texmf-context.zip

on my Terminal window and I think I will get the new version uploaded by Hans 
(my internet connection is very slow…).

Thank you for the hint…

Best regards: Otared

I had to remove these files to update from LMTX from 2020.10.20 to
version from 2020.11.05.

But I had to remove these files again to upgrade from 2020.11.05 to
2020.11.06.

I wonder whether the same happens in Windows (I haven’t checked it yet).

Just in case it helps,

cyrillic use unicode nowdays (no hurry, just wondering).

Hi, Hans. :)
Is there an analogue for display math? Could discretionaries be applicable
to math formulas when "split=yes" is enabled, for instance?

Thank you in advance.

[NTG-context] new upload

[Hans Hagen]

Hi,

In order to keep the 'context is good for toy math' reputation up to 
date, in lmtx we can now have proper discretionaries in math and math in 
discretionaries. The kind of things no one asks for but they might be 
useful in educational settings.


Here are some examples ():

\starttext

\showframe

\enabletrackers[math.toysymbol]

\definemathtoysymbol[Plus] [bin][+]
\definemathtoysymbol[Minus][bin][-]
\definemathtoysymbol[Equal][rel][=]

$\dorecurse{199} {
x_{#1} \ifodd#1\relax\Plus\else\Minus\fi
} x_{200} \Equal n$

\blank

\dorecurse{10} {
test \discretionary
{\darkred   hel  $\sqrt{y}$ lo}
{\darkgreen good $\sqrt{z}$ bye}
{\darkblue  wel  $\sqrt{x}$ come} test
}

\blank

\dorecurse{10} {test me #1
$x + 2x \discretionary class 2
{$+ \, \cdots $}
{$ \cdots \, +$}
{$+ \, \cdots \, +$} nx$ test
}

\stoptext

You might be able to guess from this code what is supposed to happen. 
I'll play a bit more with this later (assuming that it's somehow 
useful). We could predefine a bunch. As usual there might be issues but 
I'll sort them out when we run into them (it's a non critical feature 
with not much impact).

[NTG-context] new version

[Hans Hagen]

Hi,

The current version of lmtx has some updated tracing of memory usage. 
This is irrelevant for most users but some of you generat elarge an 
complex files so ... (I'm talking about mf here).


There is a command line option

  --usage

that will make a run report some more statistics. The info shown might 
look somewhat cryptic but we basically have (per category)


- max: the maximum allowed memory (for many categories we can make that 
larger, but I need proof that it's needed)


- min: this is how we start out

- stp: when more memory is needed, this is the step that we use to increase

- set: this is the value that context configures by default, often 
larger than min, and less than max


- mem: the memory usage (often in units)

- all: the real usage (multiplied by the unit)

- ini, ptr and top: are the startup values (when something is also 
stored in the format), the current usage and the max usage (all within 
the mentioned min-max range).


The rest speaks for itself. Font usage reflects only the tex end, of 
course there is plenty usage at the lua end. The language info  I 
might extend that with pattern and exception usage. Actually, tex memory 
usage is not that large in luametatex.


When mem gets increased, there is a message. We can use that to 
eventually determine the best values. Actually we might even lower some 
initial values (not that it matters much, lua uses more).


Of course there is also

  --timing

but that one has been there from the start, although I did update it to 
reflect the more detailed tracing. The graphics are the same as always: 
red lines are usage, the blue line is the runtime.


In general, memory management has been improved: all categories are now 
more dynamic, there is more checking for overflows, there is some 
recovery slack in allocation, etc. I will play a bit more some of it, 
for instance we might end up with more detailed configuration options, 
in addition the the already new ones.

[NTG-context] new upload - matching gimmick

[Hans Hagen]

Hi,

For those who like playing around you can use lua pettern matching in a 
match loop:


\starttext

\doloopovermatch
{(\letterpercent w+) *(\letterpercent w*)}
{aa bb cc dd}
{
  [
\doloopovermatch
  {(\letterpercent w)(\letterpercent w)}
  {#1}
  {(##1 ##2)}
\doloopovermatch
  {(\letterpercent w)(\letterpercent w)}
  {#2}
  {(##1 ##2)}
  ]
}

\blank

\doloopovermatch
  {(\letterpercent d+)}
  {this 1 is 22 a 333 test}
  { [#1] }

\blank

\doloopovermatch
{(.-)\letterpercent{\bf (.-)\letterpercent}(.*)}
{this is {\bf a} test}
{#1{\it not #2}#3}

\blank

\doloopovermatch
  {([\letterpercent w]+)}
  {\cldloadfile{tufte.tex}}
  { [#1] }

\stoptext

Probably not that useful (I never needed it but that doesn't say much) 
but it fits in the repertoire of loops.

[NTG-context] new upload - hyphenation

[Hans Hagen]

Hi,

One can suppress hyphenation with:

  \setupalign[nothyphenated]

but it has some limitations. The low level switches are \nohyphens and 
\dohyphens. Anyway, this mechanism has now been improved a bit:


\starttext

\startbuffer
NEDERLANDS\par Nederlands\par nederlands\par
\CONTEXT  \par test\-test\par test-test \par
\stopbuffer

\blank \start \nl \hsize 2mm\getbuffer \stop \blank
\blank \start \nl \hsize 2mm \nohyphens \getbuffer \stop \blank

\startbuffer
\nohyphens NEDERLANDS {\dohyphens Nederlands} nederlands\par
\stopbuffer

\blank \start \nl \hsize 2mm \getbuffer \stop \blank

\startbuffer
NEDERLANDS {\nohyphens Nederlands} nederlands\par
\stopbuffer

\blank \start \nl \hsize 2mm \getbuffer \stop \blank

\stoptext

We can (and probably will) add more granularity in this but now 
\nohyphens will also deal with explicit \discretionary (as used in the 
\CONTEXT definition) as well as \- and - in addition to the normal 
pattern driven hyphenation. It also obeys grouping.


(this improvement concerns lmtx only)

Hans

[NTG-context] new upload

[Hans Hagen]

Hi,

I uploaded a new lmtx ... not much done due to the heat (entered reading 
mode instead) but ... apart from some work in progress ... we now have 
some basic bitwise operations (maybe we need some more). So far we have:


\startlines
\meaning\bitwiseset
\meaning\bitwisenot
\meaning\bitwisenil
\meaning\bitwiseand
\meaning\bitwiseor
\meaning\bitwisexor
\meaning\ifbitwiseand
\stoplines

used as:

\scratchcounter = \bitwiseand "01  "02 
\uchexnumbers{\scratchcounter} \quad
\scratchcounter = \bitwiseand "01 with "02 
\uchexnumbers{\scratchcounter} \quad
\scratchcounter = \bitwiseand "03  "02 
\uchexnumbers{\scratchcounter} \par


\scratchcounter = \bitwiseor  "01  "02 
\uchexnumbers{\scratchcounter} \quad
\scratchcounter = \bitwiseor  "01 with "02 
\uchexnumbers{\scratchcounter} \quad
\scratchcounter = \bitwiseor  "03  "02 
\uchexnumbers{\scratchcounter} \par


\scratchcounter = \bitwisexor "01  "02 
\uchexnumbers{\scratchcounter} \quad
\scratchcounter = \bitwisexor "01 with "02 
\uchexnumbers{\scratchcounter} \quad
\scratchcounter = \bitwisexor "03  "02 
\uchexnumbers{\scratchcounter} \par


\scratchcounter = \bitwisenil \bitwisenil "0F "02 "01 
\uchexnumbers{\scratchcounter} \par
\scratchcounter = \bitwisenil \bitwisenil "0F with "02 with "01 
\uchexnumbers{\scratchcounter} \par


\scratchcounterone\zerocount

\scratchcounterone \bitwiseset "FFF
\ifbitwiseand  \scratchcounterone "800 YES \else NOP \fi
\ifbitwiseand  \scratchcounterone "F00 YES \else NOP \fi
\ifbitwiseand  \scratchcounterone "100 YES \else NOP \fi
\scratchcounterone \bitwisenot \scratchcounterone
\ifbitwiseand  \scratchcounterone "800 YES \else NOP \fi
\ifbitwiseand  \scratchcounterone "F00 YES \else NOP \fi
\ifbitwiseand  \scratchcounterone "100 YES \else NOP \fi

\scratchcounter \bitwiseand "01 "02
\scratchcounter \numexpr"01+"02\relax

\ifcase  \bitwiseand \scratchcounterone \plusone \else \fi
\ifbitwiseand\scratchcounterone \plusone \else \fi
\ifnum   \scratchcounterone=\plusone \else \fi

A while ago I played with bitwise operator sin \numexpr but in the end 
removed that because it's messy with the symbols to be used, but I will 
look at that agaon if needed.

[NTG-context] new version

[Hans Hagen]

Hi,

I uploaded a new version. There have been no changes to the typesetting 
machinery although we're still in the process of finetuning some updated 
low level macros. There was a fix in the font machinery (thanks to Kai) 
but that will probably go unnoticed as the issue has been there for years.


Now, that doesn't mean that nothing has been changed. First of all there 
is a new data related mechanism. After Wolfgang had updated the 
definition files it became official. It was on the agenda for a while 
but finally a nice solution surfaced.


The new thing is luatables that obey grouping. Normally what you do at 
the lua end is kind of global, but there can be cases where you really 
want it to behave like tex: obeying \bgroup/\egroup, { } etc. The 
examples given below show that you can create them at the tex end and 
access them in tex as well as lua.

This is only available in lmtx (until i see a real reason to cook up an 
alternative for mkiv, which is unlikely as no context code depends on 
this being available, at least not now). The datavalue macro you see 
there can be used to create massive amounts of numeric variable 
independent of counters, not that we really need it, but it was very 
cheap to implement.


At the engine level there also have been some changes but these should 
not be visible for users. We just mention:


- extensions to the macro definition and expansion mechanisms (for 
instance optional arguments, optional delimiters, and silent error 
recovery; there will be some explanation in the evenmore document and at 
some point - when stable - in the manual) .. this permits some cleaner 
low level code; only things were done that had no impact on performance 
(as macro definition and expansion is used a lot) and didn't make the 
code messy (it actually became cleaner)


- some additional substring (ok, tex has no string, just tokens) parsing 
capabilities with optional tokens, which again permits a bit cleaner low 
level code


- a slightly reorganized handling of tokens (one of tex's basic data 
structures) in the lua token interface so that we get a more meaningful 
and robust subsystem (basically getting rid of funny numbers) ... this 
also will be discussed in an evenmore chapter .. not that users need it 
(i think)


- as a side effect (or necessity) some low level recoding (and 
abstraction) had to happen but as far as we can see it works ok (i admit 
it was a slow, tedious job with lots of intermediate testing on the 
suite to make sure nothign was broken) .. in the end it was all doable 
because most of the preparation was already done over the last years


- in the process we got rid of a traditional tex data structure that was 
left over from the 32 bit times but no longer needed in our 64 bit 
luatex/luametatex universe (i might backport that 

[NTG-context] new lmtx upload

[Hans Hagen]

Hi,

The tex engine has at most 65K dimen and count registers and these can 
be local and global (although mixing these two models for the same 
variable can be inefficient).


Anyway, in the current upload there is a mechanism for using way more 
variables, global ones, that are managed by lua:


\luadimen test 100pt

\scratchdimen = .25 \luadimen test

\the\scratchdimen

\the\luadimen test

So, they act as normal dimensions and counters wrt assignment and 
serialization and such. There are also floats and booleans (in addition 
to integers and cardinals).


Then, as another experiment, there are one/two dimensional arrays of 
variables. Think of:


\newarray name whatever type integer nx 100 ny 500

\arrayvalue whatever 20 30 1024

\the\arrayvalue whatever 10 30

\the\arrayvalue whatever 20 30

\the\arrayvalue whatever 30 30

Some more info can be found in the last chapoter of the evenmore.pdf 
document. The question is: do we need this, and if so, do we need more 
of that. It's a bit chicken-egg case: we can have lua and can pipe back 
to tex, and we can stay at the tex end.


This is a lmtx only feature. Just for the record: these are macros, not 
primitives, but they are rather efficient and have hardly any overhead.


The floats can be in 1.23 format, 1.23e45 format and also in 0x12p34 
format, while integers can be in 123 format and 0x123 format; the hex 
float format is lua's way of being roundtrip.


Hopefully there are no side effects.

Hans

(1) - context (including luametatex sources)
(2) - binaries (for a subset of platforms)
(3) - resources (like fonts and such)
(4) - modules (stable ones pushed from the main garden repos)

but we simply didn't find time to follow up on that. We have to adapt 
installers too and we want to do it right from the start.

Now, we're not in a particular hurry, but in playing with all this it can 
happen that the current distributions get flaws.

(As a side effect the more or less official release of luametatex has been 
postponed a few times because it depends on (1) which in turn depends on 
pushing older context distributions etc. But then, due to the current health 
crisis, time has slowed down anyway.)


Sounds good. Is documentation part of (3) or can it be another section?


It's part of (1) as it is now but of course we can have an additional 
one (5) for extra documentation.



While I want to install "everything" on my work machine, it would make sense to 
restrict a server installation (or a beta version for tests) to the bare minimum (without 
docs, but maybe with fonts).


Nowadays even 'everything' is not that much is it? not compared to the 
whole of tex live. There was a time that a tex installation was 
considered large but nowadays many single task programs come with a 
larger installation.



I also would very much appreciate to be able to install older versions (like "in the 
old times") to check when some changes happened. Git repositories serve the same 
purpose, probably even better.

I’d suggest to keep those sections in separate repositories and install them as 
texmf-context, texmf-fonts, texmf-docs or the like (similar to the current state, but 
selectable). Git submodules *should* work to combine several repos, but the 
implementation has flaws (e.g. "git submodule update" tries to access all 
submodules at once, and if you must enter credentials, the prompts get mixed up).

Basically we're talking

(1) texmf-context(tex, mp, lua sources, documentation, luametatex code)
(2) texmf- (luametatex and luatex bin)
(3) texmf(mostly fonts as it is now)
(4) texmf-modules(from the garden)

and if you want

(5) texmf-docs

but context documentation goes into texmf-context.

We're not going top be too clever ... these systems come and go (as do 
some 'standards') so any installation model should be simple kind of 
'copy/fetch something' (with no dependencies on anything we don't have 
in the repository either, apart from a compiler is one wants to compile 
luametatex for some platform we don't provide).


Keep in mind that for specific usage demands are too different so all we 
can do is provide what there is.


Also keep in mind that too much split also makes for tricky 
dependencies, for instance binaries are the latest so when you want an 
older context - something that you can do now too when you use the 
existing github repository - you have to make sure you have the right 
binary. This is why (1) will have the engine source code: integrity 
(don't worry the source code compresses to < 2 meg and uncompressed is 
less that some of these large fonts).


Anyway, once we have it we can always make clever installers. Actually 
when you want to go real small it's easier to just install and wipe what 
you don't need.

[NTG-context] New to metapost, could use some help with first steps

[Gerben Wierda]

Hans was so kind to help me with a setup for some generated output. I am trying 
to understand every line of his example so I can expand on his exmaple to make 
it fully functional. In his example there is:

context('draw 
textext("\\framed[frame=off,offset=5bp,align={middle,lohi,verytolerant,broad},width=%sbp]{%s}")
 shifted center AllNodes[%i] ;',w,name,i)

as command to draw a node and the node type is defined like this:
context("save ApplicationComponent ; path ApplicationComponent ; 
ApplicationComponent := unitsquare ; ") 

For a quick example this works, but ‘unitsquare’ is a simple thing. How do I 
create a more complex shape that is reusable? What if I would like the path to 
be like this:



With this as the complex behaviour of the shape
The font size scaled so the label fits inside the image (choice yes/no)
The small boxes sized according to the font size or sized according to the box 
size (choice text/box)
The bounding box following the actual complex outline
The upper of the two small boxes in line with the upper text line (in case the 
size is coupled to the text size)
The colour of the background a default colour or given as parameter

This is one of the more complex shapes, if I can do this one it might give me 
enough information to define all the other ones. Sorry to bother all of you but 
the learning curve is steep and I always have not enough time.

[NTG-context] new lmtx beta

[Hans Hagen]

Hi,

I uploaded a new beta (mostly lmtx). Challenged by Mojca we managed to 
get native compilation under mswindows working in visual studio (and 
soon the compile farm will do several windows compilation variants) so 
future installation can have either native binaries or crosscompiles 
(they have comparable performance with the native ones being a bit 
smaller). The current upload still has crosscompiled binaries.

Re: [NTG-context] new beta

[Otared Kavian]

Hi again,

I just installed anew lmtx from Pragma website

http://lmtx.pragma-ade.nl/install-lmtx/context-osx-64.zip

and I have the same problem: the format cannot be made.
Looking at luametatex in a Terminal window, I get

-rwxr--r-- 1 kavian staff 2.7M Dec 6 13:15 
/context-osx-64/tex/texmf-osx-64/bin/luametatex*

and I cannot tell whether it is old or recent, but typing

luametatex --version 

gives among other things:

Functionality : level 20191029

Is this too old? Is this file created during installation or is it contained in 
the zip files downloaded from Pragma's site?

Thanks for any help,
Best regards: Otared K.

You Luametatex binary is too old which missed the new \adjustspacingstep

That's strange. I indeed see these lines in 'hand-ini.mkxl' but I could
recreate format without problem on my Linux box (Archlinux x86_64), even
after clearing the cache and doing

  $ mtxrun --generate ; context --make

gives me working context (lmtx).

I tried two examples with lmtx and they typeset fine.

[NTG-context] new beta

[Hans Hagen]

Hi,

I uploaded a new lmtx beta. Hopefully the installer works ok as I redid 
some of the "zip" related code (simpler, smaller binary too). FWIW, the 
luametatex codebase is now pretty close to okay, but of course there can 
be bugs, but nothing thay can't be solved fast.


Given some earlier discussions on the list, I wonder about running 
context in containers and (behind the screens) web applications. Is 
there anything needed, mostly in the support scripts I guess, that can 
make that more comfortable / efficient / etc?

Many thanks for the new beta, Hans.

I cannot find any of these documents (in MkIV, with first-setup.sh
installer):

tex/texmf-context/tex/context/interface/mkiv/i-context.pdf
tex/texmf-context/doc/context/documents/general/qrcs/setup-en.pdf
tex/texmf-context/doc/context/documents/general/qrcs/setup-mapping-en.pdf

It doesn’t seem to be renamed (at least, to me).

BTW, I cannot compile this sample with MkIV :

\starttext
a
\stoptext

Here you have the error message:

tex error   > tex error on line 133 in file math-ini.mkiv:
! Undefined control sequence
l.133 \ordlimits
  \limits

LMTX has no problems with this. Could you fix this in MkIV?

Many thanks for your help,

Pablo

Hi,

I uploaded a new beta. Apart from some fixes, the main change in lmtx is 
that on windows most (a few exceptions) of the mechanisms that interface 
to the operating system support the internal wide character model which 
should make the lot more robust for file names, environment variables, 
command line options etc that (at the tex/lua end utf8) have characters 
other than ascii. Another improvement in lmtx is support for ancient 
type 1 fonts (like the type 1 lucidas) but that's more 'being complete' 
than a 'real need' (when such fonts are used wiping the cache is 
needed). Both these (lmtx only) patches can have unforseen (by me) side 
effects but nothing that can't be fixed fast.

I think that it is better to use the same name if there is no special reason to 
distinguish, and I prefer to use “function | functions”.  
However, I am OK whether you keep both or choose one. 

Thank you and your team again.

[NTG-context] new beta

[Hans Hagen]

Hi,

I uploaded a new beta. Some might have noticed that stepwise some font 
support has been redone. We're talking of lmtx only here. For instance 
low level handling of color fonts as used for emoji but there are also 
other (often incomplete) fonts out there (overlay, png, svg) has become 
(on the average) a bit more efficient. It's somewhat tricky to satisfy 
viewers but at my end things work ok. It should also work in a cmyk only 
mode. As usual it's work in progress (and in this case very likely lmtx 
only).


Also some first (runtime) metafun (2) font creation support has been 
added (was always possible but it's a bit more convenient now). An 
example can be found in: meta-imp-gamesymbols.mkxl (the file can be 
processed with the 'context' command and will produce an example).


As usual imagination determines the limits of what context provides, so 
feel free to suggest more (examples). Again this is lmtx specific.

Hi,

I read the new manual with a great joy! This is really nice improvements of
MetaFun! I also like the 3D plots!

I had the possibility to try out some contour graphics on a freshly updated
system. I have two questions:

1) I think the first (blue) plot looks fine and it looks like it could be
the same curve as the blue one in the Mathematica plot (page 3). Why does
my second example (orange) not match with the result from Mathematica
(orange)? (I think I do something wrong)
2) Is there a way to combine the two contour plots in one MetaFun drawing?
If I add them both to the same, only the last one shows. If I try
functions={"-4+x^2+x^5+15*y-y^2-10*x^3*y^2+5*x*y^4","-15*x+2*x*y+5*x^4*y-10*x^2*y^3+y^5"}
it does not show both either.

Hi,

I uploaded a new lmtx beta. Again some more metafun trickery (see 
luametafun manual). I attached an (lmtx only) example of some experiment

[NTG-context] new LuaTeX binaries in latest beta

[Pablo Rodriguez]

Dear list,

I have just downloaded the latest beta from the ConTeXt Suite and I
found that it includes the new LuaTeX binaries.

These ones fix the issue reported in
https://mailman.ntg.nl/pipermail/ntg-context/2019/094266.html.

Many thanks to each one involved in the timely release of each version
of the ConTeXt Suite,

Pablo

Re: [NTG-context] New logo proposal

[Henri Menke]

Dear Paul,

Personally I really like your logo design, but there is one thing that
bothers me a lot, which is the non-free font.  Could it perhaps be
replaced by a free font, e.g. Fetamont?
https://www.ctan.org/pkg/fetamont

Cheers, Henri

The E at the center might be switched with the T at center bottom. Then the 
lower part might be easier to read, and is in line with the original TeX logo, 
where the E is a lowered capital eta.

You don’t need to understand the signs of a good logo (see e.g. Deutsche Bank).

Floris’ proposal is clear and looks like math, that’s TeX-y enough IMO.

Every good logo works without color, even if there is a color version.


Myself, I suggest a Dodo as mascot. (Save the \dodo !)

I like this.

There could even be an animated version that links the twi versions (and would 
work in (Lua)iTeX, of course).

[NTG-context] New logo proposal

[Paul Schalck]

Hello again,

as many critics go towards "I don't see any coherence" or "to me it's just a 
random bunch of colored letters" or "it's hard to read the word CONTEXT", some 
afterthoughts in that regard (difficulty, randomness).

Personally, I like visual material that catches my attention, but does not give 
all away at first glance. For example a good poster or book cover. It invites 
me to spend time on it. And I don't have the feeling that the designer thinks 
I'm stupid. ConTeXt is quite sophisticated, its logo can also be a little bit 
more complicated than your average sportswear brand.

Any color choice is arbitrary to some extend. The colors I've used cover the 
entire hue range and are at equal distance apart (common in multicolored 
designs). This denotes to me not only the flexibility, and the fun of using it, 
but also the comprehensiveness of ConTeXt. Not only can you use ConTeXt in very 
different situations, you can use it in every situation (that requires 
typesetting).

My 2c!

Greetings,

Paul

Re: [NTG-context] New logo proposal

[Lars]

Although I don't think that it's a good idea to paint a car which 
doesn't work as it should in uncountable situations, I'd like to make a 
suggestion:


When you're over the decision which tone the blues and reds should have, 
please put an .ico file or similar of the logo into the CTX 
distributions. My wish has to do with the way how Windows handles 
modifications to its user interface (UI). Having a fixed location and 
naming structure for a file icon would be a big improvement.


If the CTX distribution always downloaded the logo.ico to some place 
which I just didn't find yet, ignore this mail.


Thanks sincerly, Lars.

It is useless to argue about taste, but it may be of interest to see how 
users react. I would agree with Willi. The colors look too random to me. 
A fine-tuned palet with  a smaller range of colors that are visually and 
intuitively related would be preferable, IMHO. But again: de gustibus 
non est disputandum; if Paul likes this look, he should by all means use 
it in his presentations and documents.  And of course, thanks for

There is no real need to display the letters “context”.

For use in actual text we already have \CONTEXT.

[NTG-context] New logo proposal

[Paul Schalck]

Hello,

thank you all again for your reactions. A lot of interesting comments here on 
logo design in general and a ConTeXt logo in particular. I'm honored that the 
new design has found its way into the Wiki, thanks Taco!

@Lukas: I like the idea. Would be worth a try.

@Floris vM: I'm glad that my nemesis on the matter felt himself challenged to 
make his own proposal. While I think it's too minimalistic (only insiders know 
what 'CTX' stands for), I like your idea of the subscript 'T'. Your concept 
with the crosses reminded me of the visual identity of Amsterdam. I do not see, 
however, how it reflects better "typesetting beautiful readable typography". 
And it lacks some colors ,-)

Greetings!

Paul

Re: [NTG-context] New logo proposal

[Procházka Lukáš Ing .]

Hello,

thanks Paul for the nice job! The colorful hexa-shaped logo seems much prettier.

One point/suggestion - if the letters "TEX" shared the same background - be it e.g. light gray - it might be 
cleaner how to read ("discover") the word "ConTeXt"; it would also keep the hexagonal shape, 
associating chemistry; and it would also indicate or highlight relation to "TeX".

But keep my notion or feeling just personal; the new logo is "nice enough" as 
published on wiki.

Best regards,

Lukas

I do agree ;-)


Here’s an attempt the blend the lines in plain monochrome …
The latter having a naive reference to the typical TeX letter dropping

e.g. always room for improvement ;-)

Re: [NTG-context] New logo proposal

[Taco Hoekwater]

Hi,

While this discussion is going on, it is still the case that Paul’s
new unofficial logo is better than the old green one, so I did 
in fact replace the wiki logo. It will stay up until someone 
comes up with a proposal with a higher level of consensus.

Thanks Paul!

Taco

PS I tried replacing the favicon as well, but the image does
not want to scale down that much, so the favicon is still Patrick’s 
tulips.

Could you elaborate on how ‘fun’ in colors is defined?
I see no coherency in the color palet.

How about a one color logo without any text?

Dear ConTeXt users and developers,

I want to submit a new ConTeXt logo to you (link to GitLab project):

https://gitlab.com/schickele/new-context-logo

I made this logo in February 2018. At the time, I was planning to do 
some video tutorials on ConTeXt (still work in progress), and I wanted 
a nice looking visual clue for the thumbnails. Recently, I made a few 
minor tweaks and thought it would be the right time to put it out there.


The logo comes in two different layouts (hexagonal and horizontal), 
and each layout comes in two color variations (multicolored and blue).


The hexagonal layout is borrowed from the unofficial ConTeXt logo that 
has been around for some time. I like the idea of a clean geometrical 
form, and the hexagon reminds me of chemistry formulas -- one of the 
many application fields of ConTeXt.


The seven colors have mainly an esthetic purpose. They also denote the 
flexibility of ConTeXt. I've added a monochromatic blue version 
because shiny, saturated colors are not suitable for every case, and 
blue is strongly associated with ConTeXt to me. Blue is also a 
reminder of Mark IV and LuaTeX.


The letters are set in Din17 EF, which I've licensed. I like its 
simple shapes combined with a round and soft touch. It avoids 
consciously the very connoted Computer Modern and can be seen as a 
modernized and also Europeanized interpretation of the TeX tradition.


This logo is just a humble proposal. Perhaps it is of some use to 
someone. It could also make someone else want to create and share his 
or her logo -- that would be great.


I'm using ConTeXt since 2006/07 for almost everything that contains 
text: letters, presentations, invitations, résumés, certificates, 
manuals, reports, flyers, university papers, book typesetting, 
exercise sheets, song sheets, and I'm still amazed by how powerful, 
flexible and reliable it is. Thanks to the whole community -- and 
particularly to the Dutch wizard -- for making this possible!

ConTeXt is a derivation of TeX, a creation of Donald Knuth.  Here is what he 
said about the logo for TeX:

   "English words like 'technology' stem from a Greek root beginning with the 
letters τεχ...; and this same Greek word means art as well as technology.  Hence the name 
TeX, which is an uppercase for of τεχ."

And:

   "... it's important to notice another thing about TeX's name: The 'E' is out of 
kilter. This displaced 'E' is a reminder that TeX is about typesetting, and it 
distinguishes TeX from other system names."

The new design loses this characteristic and therefore does not distinguish it "from 
other system names".  The same could be said for the unofficial logo on wiki.

Personally, I think the ConTeXt logo should maintain the link with TeX and its 
design principles.  After all, that is how ConTeXt derived its name and 
functionality.  But this is just my opinion!
But the \TeX thing is the in running text used one so that will always 
stay texie.

so you use english .. dutch is not bad either with 20


i agree, we need a native \scrabblescore function to add the total letter score 
at the end of each document typeset by context ;-)


This is the scrabble coun tof the luatex manual:

What are you trying to improve over the original?


(For the horizontal version, i’d prefer at least the correct letter 
values in place ;-)

interesting: it adds up to 16

Subject: [NTG-context] New logo proposal

Dear ConTeXt users and developers,

I want to submit a new ConTeXt logo to you (link to GitLab project):

https://gitlab.com/schickele/new-context-logo

I made this logo in February 2018. At the time, I was planning to do some video 
tutorials on ConTeXt (still work in progress), and I wanted a nice looking 
visual clue for the thumbnails. Recently, I made a few minor tweaks and thought 
it would be the right time to put it out there.

The logo comes in two different layouts (hexagonal and horizontal), and each 
layout comes in two color variations (multicolored and blue).

The hexagonal layout is borrowed from the unofficial ConTeXt logo that has been 
around for some time. I like the idea of a clean geometrical form, and the 
hexagon reminds me of chemistry formulas -- one of the many application fields 
of ConTeXt.

The seven colors have mainly an esthetic purpose. They also denote the 
flexibility of ConTeXt. I've added a monochromatic blue version because shiny, 
saturated colors are not suitable for every case, and blue is strongly 
associated with ConTeXt to me. Blue is also a reminder of Mark IV and LuaTeX.

The letters are set in Din17 EF, which I've licensed. I like its simple shapes 
combined with a round and soft touch. It avoids consciously the very connoted 
Computer Modern and can be seen as a modernized and also Europeanized 
interpretation of the TeX tradition.

This logo is just a humble proposal. Perhaps it is of some use to someone. It 
could also make someone else want to create and share his or her logo -- that 
would be great.

I'm using ConTeXt since 2006/07 for almost everything that contains text: 
letters, presentations, invitations, résumés, certificates, manuals, reports, 
flyers, university papers, book typesetting, exercise sheets, song sheets, and 
I'm still amazed by how powerful, flexible and reliable it is. Thanks to the 
whole community -- and particularly to the Dutch wizard -- for making this 
possible!

Greetings from Leimen, Germany

Paul Schalck
