[Steffen Wolfrum]

Hi Hans,

quite often I wish we could have a kind of in line comment:
Something like ¿this is my comment¡ this.

I assume it is not trivial due to catcode issues, to say the least.
But nevertheless, as it is getting close to christmas, I just wanted to mention this idea here.

Thanks,
Steffen

Isn't there already \comment{…}?

The \comment command can be used to add PDF comments to your document, IIRC it’s documented in the widgets manual.

\usemodule[annotation]

\defineannotation[hide][alternative=none]

\starttext
Something like \hide{This is my comment!} this.
\stoptext

A simple definition of the hide which doesn’t require the annotation module is:

\define[1]\hide{\removeunwantedspaces}

I think the mechanism for fancy in-line comments is already there,  
developed one-or-two years ago as we were working on some  
critical-edition-related stuff ...

I saw the other answers: Could you elaborate more about exactly what  
you're looking for, just in case their suggestions don't quite hit the  
spot?

I am looking for the same functionality as the traditional TeX comment (starting with %), but used in-line not only after a paragraph.

This means, it is only meant for writing/reading comments in the source. 
And its presence must not affect the typeset file, eg. the resulting PDF, in any respect, of course!

Is the mechanism you mention best suited for that purpose?

That sounds a bit strange, because a paragraph doesn't end with a line 
break. That's how I usually do my comments too; just add a comment and 
continue after the line break with the content/sentence/paragraph:

-----8<----------------
This is %some comment
an example.
----->8----------------

... will end up as: "This is an example."

maybe "paragraph" was the wrong word (even though in your example between "comment" and "an" there is a pilcrow too, which is commonly used to denote individual paragraphs).

that's what I meant: a true in-line comment ... without a line-break, parapgraph-break, pilcrow for ending the comment:

This is ¿some comment¡ an example.

and next one would want:

This is ¿some
comment¡ an example.

and

\startchapter[title={This is ¿some comment¡ an example.}]

and ... so it's asking for a mess.

Just use a command as Wolfgang mentioned.

As long as there is no line break in the comment, the following lua based 
solution works (inspired by m-translate)

\startluacode
   local comments = {}
   thirddata = thirddata or {}

   thirddata.comments = comments

   function comments.translate(s)
       return string.gsub(s, "¿.-¡","")
   end

   utilities.sequencers.appendaction(textlineactions,"after","thirddata.comments.translate")

   function comments.enable()
     utilities.sequencers.enableaction(textlineactions,"thirddata.comments.translate")
   end

   function comments.disable()
     utilities.sequencers.disableaction(textlineactions,"thirddata.comments.translate")
   end

   comments.disable()
\stopluacode

\def\enablecomments {\ctxlua{thirddata.comments.enable()}}
\def\disablecomments{\ctxlua{thirddata.comments.disable()}}

yes, that what I thought right away too. 
for the sake of completeness, I just wanted to answer Idris question and wait what he thinks.

Your request is a bit different from what I had in mind ...

OTOH, why not just use

bla bla \message{Here is a note to myself.} bla bla

It'll show up in the log file, but who cares?

Why not go all the way with full multiline comments then? See attached.

Here is a slightly cleanup version that handles multiline comments better

https://github.com/adityam/context-comments/blob/master/t-comments.mkvi

But this will only work if % has its usual catcode. I don't know how to 
get around that limitation.

  if find(s,stop) then
    insideComment = false
    return cleaned_line .. currentfilter(strip_to_stop(s))
  else

as find returns a position, you can do things like this:

local stop = find(s,stop)
if stop then
  ...
  return cleaned_line .. sub(s,stop+#stop,#s)

(ok, you need to know the real unescaped length of stop)

for multiline we can plug into the texthandler instead, but it's not 
worth the trouble and the line based one permits selective enable/disable

Just curious: Is there anything that \message is missing for what u want?  
I tried both inline and multiline combos and they all work like a charm:

==========
\starttext
Here is some text. \message{Given an action, the recompense is always in

As a feature, I suppose all that's needed -- for the paranoid, maybe  
you're writing a letter to your boss with hidden curses ;-) -- is the  
option to suppress the showing of the text on the console/log. Although  
it's in the source anyway ... For ¿ and ¡ probably some simple catcode  
trickery will \let you define them as you like.

So I'm curious: How can we define

¿ = \message{
¡ = } % this one is of course trivial, but for completeness...

Since you brought this up, I've actually started using \message more (and  
no, not for cursing my boss!)

You see that there are now two spaces between your sentences, compare the following two sentences:

\starttext

text \message{hidden} text

text\message{hidden} text

\stoptext

To avoid this I added \removeunwantedspaces to my \hide command.

Untested, but I am pretty sure

\message{\iffalse}

will fail. Basically, everything inside \message (or the \hide macro by 
Wolfgang) needs to be processed by TeX, so strictly speaking it is not 
equivalent to a comment.

See the TeX FAQ http://www.tex.ac.uk/cgi-bin/texfaq2html?label=conditional 
for more details.

The most robust solution is to use buffers, but that will not work if the 
buffer is part of a macro argument.

The luatex solution (which is again not perfect) that I posted removes 
everything inside the comment before it is seeen by TeX.

I began to learn ConTeXt since april and begin to write real
ConTeXt documents (mostly presentations) since june.
Please don't ask me too much.

My main request is not to provide LaTeX compatibility but
to provide not only one command of matrix but full set of commands
for various kind of matrices if possible.
Personally, it is true that I think LaTeX compatibility is useful
but it is not main issue.

Atsuhito Kohda

Hi Henri,
Thanks for your kind explanation.
Generally I understand your point and the ConTeXt philosophy.

If it is trivial to define bmatrix etc., then I think
it is not bad to provide them in ConTeXt itself but
it seems it violates the ConTeXt philosophy.
I feel it is too strict or too formalism, but this is
only my, very novice user's, naive impression.

Best regards,
Atsuhito Kohda

LaTeX compatibility is desired (by some)
1) when new to Context, coming from LaTeX and learning a new system;
2) for ConTeXt users who are *required* to sometimes use LaTeX,
   for example in submissions to journals etc. that accept LaTeX but
   cannot handle Context sources.

One gets over the first case rather quickly and then there is no
going back: the philosophies are so different.

In the second case, I restrict myself to a strict use of the journal's
own template (for example with revtex), never asking for anything more
nor anything less.

In a third situation of editors who give lip service to accepting TeX
submissions, I give them plain text for they are going to re-key in
everything in any case. I provide them with a pdf that they can use
to correct their markup.

Let me provide an alternative point of view. The commands that you are 
suggesting are encode the _visual_ meaning: pmatrix is a matrix with 
parenthesis, bmatrix is a matrix with brackets, vmatrix is a matrix with 
vertical bars, and so on. One could also use _semantic_ commands: in my 
documents, I define a command called MATRIX for typesetting matrices, and 
DET for determinant of a matrix. So, I simply type

\MATRIX{1, 2; 5, 6} and \DET{1, 2; 5, 6}, etc.

Now, depending on the audience, I sometimes map \MATRIX to pmatrix and 
sometimes to bmatrix. I can simply copy paste the code without worrying 
about notation.

If you take this view, then the predefined matrix:parentheses, 
matrix:brackets, and matrix:bars are sufficient.

You can create a private module with the definitions that you need. If 
these are general enough, then you can also release it as a third party 
module for others to use. I don't see the value of adding (and 
maintaining!) a module that provides LaTeX compatibility as part of the 
core.

Re: feature request

[Henri Menke]

The existing definition of \pmatrix in math-pln.mkiv is the original
Plain TeX definition, because in the very early days ConTeXt used to be
compatible with Plain.  This tradition has prevailed until today.  You
will find other remnants of Plain TeX in ConTeXt, e.g. \eqalign, but it
is better not to use them.

Just like Plain TeX, ConTeXt does not provide \bmatrix and \vmatrix.
One reason is that they didn't exist in Plain, but another important
reason is that Hans is not a mathematician.  If I remember correctly
ConTeXt was originally developed for typesetting of primary school
textbooks and last I checked matrix algebra was not part of the
curriculum.

Other developers (Alan, Aditya, and others) have contributed math
typesetting macros over time, but these follow the ConTeXt philosophy of
providing strong defaults but trying to avoid feature creep.  Therefore
bmatrix, vmatrix, etc. are not defined by default, but as you saw from
my last message it is trivial to define these, especially because
templates (matrix:parentheses, etc.) for them already exist in the core.

It would sometimes be nice if you could just copy and paste LaTeX code
into a ConTeXt document and it just works™, but after all ConTeXt is not
LaTeX.

Cheers, Henri

Hi Henri,
Thanks for your suggestions, they are very instructive.
However, my request is not a smart way of displaying matrices
but to know why \bmatrix and \vmatrix are not provided
in core part of ConTeXt although \pmatrix is provided already
in math-pln.mkiv

About matrices, I first found commands in your first email in
http://dl.contextgarden.net/myway/context-latex-math.pdf
(like \startpmatrix \NC A\NC B\NR \NC C\NC D\NR\stoppmatrix)
and then browsing ma-cb-en.pdf I noticed another command
like \pmatrix{A&B\cr C&D\cr}.
Now by your email, I know a command \pmatrix{A, B; C, D}

One might say ConTeXt is flexible but I've an impression
that ConTeXt is in a state of confusion/disorder.

I think it is better if a standard command is provided
by core ConTeXt or by a module etc.

Or is it ConTeXt way that each user defines his/her own commands
in setup area and uses them in text area?
I'm afraid consistency and/or portability is lost in such scenario.

BTW, I constantly convert Beamer documents into ConTeXt's
simpleslide documents recently and it is very convenient
if I can use \pmatrix{a&b\cr c&d\cr} style because it is similar
to LaTeX documents.

This should not be necessary in general.  Just use \NC and \NR.

[-- Attachment #1.1: Type: text/plain, Size: 992 bytes --]

I've used LaTeX quite a long time but recently I begin to use ConTeXt too.
So I'm very sorry if the following is well-known issue.

I find an example of \pmatrix in p.21 of "ConTeXt Mark IV an excursion"
(ma-cb-en.pdf).  And I notice it is defined in
/usr/share/texmf/tex/context/base/mkiv/math-pln.mkiv (in Debian).
But it seems \bmatrix, \vmatrix are not defined yet.
Is there any reason why they are not defined?
Similar commands or environments \begin{bmatrix}...\end{bmatrix},
\begin{vmatrix}...\end{vmatrix} are very often used in mathematical
LaTeX documents.
It is very useful if we can use \bmatrix and \vmatrix in ConTeXt
documents, so please add
\unexpanded\def\bmatrix#1%
  {\left[\matrix{#1}\right]}
\unexpanded\def\vmatrix#1%
  {\left|\matrix{#1}\right|}
in math-pln.mkiv or somewhere.

By the way, I think it is critical to set
\setupmathematics[ampersand=normal]
to use \matrix above but I can't find this setting in ma-cb-en.pdf
It is great if this is added in  ma-cb-en.pdf

otfinstall ist just a wrapper around the great lcdf type tools. For
type1/truetype you can use rfil
(http://foundry.supelec.fr/projects/rfil/).

Thanks for the heads up. Now why OTF and not type 1? There are still

1.) This is not exactly the same thing, but if we're talking about
graphics: is it possible to include a figure (\externalfigure, perhaps
withing \placefigure) in such a way that it fills exactly the
remaining avalable space? factor=fit does almost exactly what I want,
but it doesn't consider the space already taken by the preceeding
text. If I wanted a figure to span over the whole presentation sheet,
than factor=fit usually resulted in a caption on one page and a
full-page figure on a new page. (I tuned the figure sizes manually,
but that is not the proper way.)

2.) This is also something else, but what's the best way to write on
pre-printed sheets of paper? Like honourable mentions and stuff like
that.
The lines are already given, so I would like the baseline (with name &
surname for example) to be 0.5 mm above the line printed on paper,
centered on that line (not necessary in the middle of the paper)

I use
\setupframed
	[align=middle,
	 frame=off]
\setlayerframed
	[page]
	[voffset=13.3cm,
	 preset=leftbottom]
	[width=\paperwidth]
	{\MainFont #1}

for that, but it doesn't take the baseline into consideration, so it
has to be manually tuned for every line, every font & every font size
(printed and compared if it looks OK).

Yet another (probably doable, but more difficult to implement)
request: there are for example five lines printed, with the distance
of 13 mm and the width 10 cm (not necessary centered on the page). I
would like to typeset a paragraph on them, so that the baseline of
this text would be about 0.5 mm above the lines.

I volunteer to write a MyWay if someone can help me with that.

Thank you,
    Mojca

ok, agreed!

But figure labels are needed (do they interfere?)

yes I know. you once told me (as for the first time I asked for this 
feature two years ago...).

true, it's a nice trick. and I used it in smaller publications.
but it is not practicable with a lot of images (and this cases are 
the regular ones, unfortunately).

typesetting with a lot of images wrapped by text is still a quite 
problematic task in ConTeXt/TeX .

Steffen

(P.S. actually my motivation to move to ConTeXt years ago was the 
hope that this image handling might be possible there. well, it 
wasn't ... )

btw, do you know this trick?

not trivial indeed, although it is more or less doable when you accept some limitations, e.g. if you have only text and graphics, use a grid,  and have no other tricky stuff that can interfere (display math or so)

Feature request

[Steffen Wolfrum]

Hi,

it would be great if the \placefigure macro could be extended to 
combinations like

\placefigure{top,left}

or

\placefigure{bottom,outer}


The reason for this request is that we use ConTeXt a lot for 
typesetting books from "arts and humanities".

There we often have to place a lot of (more then 100) figures at 
"fixed" positions like top-outer and bottom-inner, wrapped by text.

I guess it's not a trivial feature to be implemented in TeX's 
paragraph processing, but I know it might be worth the effort: 
ConTeXt's way to deal with fonts and text is so superior that it 
should be also accessible for disciplines that besides text also rely 
on images - as the arts and humanities do.

Steffen
