hm, i prefer to start from user demands and personal needs; we used
latex for
a very short time and i don't remember mini pages -)
Ok, but what I mean is the need of such a documentation on the
ConTeXt core, not
reimplementing LaTeX in ConTeXt !
I'm not sure that ConTeXt \framed command is able to reproduce
the parbox behavior (position a framed box relatively to its
internal top
or bottom line and the outside baseline)
i think we can safely assume that all these things are available
somehow
(supp-box.tex implements a lot of box types)
I saw this source file thanks to the following URL:
http://source.contextgarden.net/supp-box.tex
There is very much interesting macro, but I see some
%D \macros
%D {strutdp,strutht,strutwd}
%D ...
Does it mean that an automatic generated documentation is available
somewhere
on the web?
Or is it mondatoryto browse the source for using these command.
normally \framed can do what's needed, so in your case, if you can
make
clear what you want to achieve i'm sure that someone on this list can
provide the answer
... So what is the current reference documentation about framed
- Context the manual (page 206) ?
- ConTeXt an excursion (page 45) ?
the manual as well as examples inside the core-ful.tex file
I haven"t been able to find this file!
core-fil.tex exists but doesn't seem to be about using boxes!
the most important properties of framed are
- offset (none,overlay, dimension)
- align (all kind of combinations)
- width/height (dimension or keyword)
- strut (yes|no)
just play a bit with it and you'll see the picture
Thank you for these informations, I reread the (box related) reference
manual, and better understand the thing!
...
I think there has to be two pairs of informations to position a
box (i.e. a "cell" text):
- how is the box is positioned relatively to its environment (the
location=
keyword I think),
no, location is limited to a few options; you can use macros
like \offset[...]{} or other box positioning macros; layers
are also an option
Although I guess what it mean, I didn't found the \offset command
doc neither. I suppose it has numerous
interesting options (on http://texshow.contextgarden.net/)?
- inside the box : everywhere. that implies two reals numbers
between 0.0 and 1.0 (perhaps wider?)
what are those numbers representing?
It could just be a way to specify arbitrary position between
left (0.0) and right (1.0) or between bottom (0.0) ant top (1.0)
But the more important whould be a (uptodate) reference documentation
about
the already existing commands.
(but the TeX command \raise0.5ex could do that)
indeed, \raise and \lower and cousins can come in handy
Yes, I always forget TeX command! thank you very much !
(what do you use those minipages for?)
These are just (v?)boxes which can contain several paragraphs
and theyre own footnotes. Some options can be use to position
theyre internal (top or bottom) line relatively to the external
base line.
No need for now, I only used them in LaTeX for building some boxing
construction. But in context I used vboxex into hboxes (because I
didn't kwox enough about standard \framed command)
In fact, ConTeXt already contains all the needed stuffs, and only
some centralised documentation for using them is missing!
I'm waiting for the future ConTeXt book ;-)

PS.
Also the ConTeXt wiki becomme more and more rich in information!
Thank you very much for all that
!

i dunno what those are, vboxes?
Not sure what exactly is "vboxes" (something you can put in hbox? yes
it is) but LaTeX
raisebox, parbox, minipage can be put inside a text line.
minipage can manage its ones footnote, but this is not the question
here.
As the "LaTeX++" concurrent package designer, you should read some
page of the
LaTeX reference documentation "A document Preparation System"
It is little book (272 pages with the index !) and cover the core of
the
package.
Page 103 to 110 are related to boxes, and is what is missing in context.
I'm not sure that ConTeXt \framed command is able to reproduce
the parbox behavior (position a framed box relatively to its internal
top
or bottom line and the outside baseline)
in most cases you can use framed (make sure that you set 'align' to
something in order
to enter vmode)
framedtext is a bit more clever and handles some spacing issues
With your help, and some old reference doc and the wiki
(http://wiki.contextgarden.net/Vertically_Centered_Boxes)
I tested the following "one line text" which works.
(My version of TeXExec 5.2.4 doesn't seem to support \startframed and
\stopframed so I use \framed instead).
\starttext
% align:no left right middle normal high low lohi justified
% location: low depth hanging
a word and --%
\framed[width=.2\textwidth, align=flushright, location=depth]{
some stuff
}%
--%
\framed[height=3em,width=11em, align={flushleft,lohi},
location=hanging]{
other stuff
}%
--%
another word, same line
\stoptext
But more generaly, there is a frequent need about boxing stuff and it
seems that the \framed command is the way to go. But it's not always
easy to guess the various parameters to get an expected behavior.
So what is the current reference documentation about framed
- Context the manual (page 206) ?
- ConTeXt an excursion (page 45) ?
Such a command is usefull inside some "hardcoded" slide.
And there could be a "\boxed" or "\cell" macro with default
"frame=off" parameters just to serve as special tabular cell.
I think there has to be two pairs of informations to position a
box (i.e. a "cell" text):
- how is the box is positioned relatively to its environment (the
location=
keyword I think),
- how to position the stuff **inside** the box (align= keyword)
What is the need for these 2 parameters :
- inside the box : everywhere. that implies two reals numbers
between 0.0 and 1.0 (perhaps wider?)
with some keyword for predefined values (flushleft, middle,
flushright
low, high, lohi and baseline,
(vjustified, justified=hjustified serve another feature)
- outside the box : only verticaly ?
one real number [0.0..1.0] plus low depth (=base?) hanging (=top)
Here a parbox provide an option for aligning the external baseline
on the "top" ou "bottom" internal line.
How can I simply optain the "0.5 = vertical middle"
Probably the positionning parameters for outside the box are more
complicated : more than the internal reference point mention above is
to which external reference point the inetrenal point should be
aligned to ?
Generaly the baseline of the parent is the choosen one, but
perhaps one
like to use the "0.5ex hight" one as in minus sign in the "3-2,"
string
(but the TeX command \raise0.5ex could do that)

Re: [NTG-context] framed texts and other "minipage"
Le 7 janv. 06 à 13:50, Hans Hagen a écrit :
No, that will not work.
After much probing I found the culprit.
The framedtext takes the full linewidth and apparently does not
reduces it to the given size.
Therefore enclosing in a vbox seems necessary:
\vbox{\hsize=framesize\startframedtext{width=framesize ...
Question for Hans Hagen: is it an option letting framedtext set
the hsize when a specific width is given?
\hbox to \hsize \bgroup
\startframedtext[none][width=.5\textwidth]
\input tufte
\stopframedtext
\startframedtext[none][width=.5\textwidth]
\input zapf
\stopframedtext
\egroup
Why is it not possible to simply use the \framed command (with some
magic option to
put text into it) to do the obove thing?
\startframed[width=.5\textwidth, ]
\input tufte
\stopframed
\startframed[width=.5\textwidth, ]
\input zapf
\stopframed
If it is impossible, is there any equivalent to de minipage or
\parbox LaTeX
equivalent?

[NTG-context] High level user macro (howto?)
Bonjour à tous,
One thing is missing in context (or not documented in reference manual?)
is a standard and easy way to build arbitrary parametrised high level
macros.
For exemple, instead of
\def\myCommand#9{...}
That I should call by
\myCommand{param1}{param2}{...} {param9}
Id'like too keep default value for most of the parameters but param7
and write something like:
\myCommand[param7=value7]{body}
In LaTeX, there is a package keyval for doing this
And context use this everywere, but I haven't seen anything for
a user beeing able to do this.
This is the base for building arbitrary complex user commands with
some defauld behavior, and then, if this personal macro is usefull
enough, building some user contribution library.
As a true exemple, see a latex package I've written some years
ago for drawing uml diagramms whith LaTeX command (using PsTricks).
This file is available at
http://www.ensta.fr/~diam/latex/pst-uml/pst-uml-981218-09h41.tar.gz
(should now be available on CTAN too)
See documents for the samples (in french but the samples are in LaTeX
and
drawing are in "picture" !)
One of the first exemple I'd like is some command to put some little
table as caractere in a line (see that as some personalised box):
start of line
$-$\myStack[border=1ex,baseline=0.5]{
aaa & bbb \\
aaa & bbb \\
aaa & bbb
}$-$
end of line
Or a little command to draw some picture, with default but modifiable
parameters:
$-$\myzigzag[dir=down,linewith=1pt,color=red,with=3\em]$-$
Using Metafun.
Cordialement,

I also know that such a task is not feasable by only one person (even by Hans :-) as long as one builds on top of the system and support modules (syst-*.tex and supp-*.tex) or uses high level constructs, one can write extensions -) About extension, I'd like some way to create new context command with the possibility to pass "intelligent" parametres system: but see my separate post "High level user macro (howto?)"

(I havn't been able to find the beta tex4ht recently mentionned here) And nobody will contribute in a project that it hasn't fully adopted! hm, keep in mind that in the beginning of tex there could be some influence on that (read: amstex and latex were pushed by user groups in favor of for instance lamstex, inrstex, etc) ; You are right: and I hope ConTeXt will becomme the standard (:-) For this, one need: 1 - a clear polilical objective for context, hm, i'm not going to promise context-2 (like latex-3), but here are a few things on my agenda: - some clean up of code and maybe even rewrite of parts of the code (esp lists and section handling) - converting the low level dutch into english (can be done automatically -i did that some years ago-) but i need a moment of 'silence' for that I heard from some poeple (potencial contributors) for which this was a great default for context (internal documentation) - support for xsl-fo (i occasionally work on that, when i can motivate myself); much of it is finished does it means that there will be some user way to convert context file to html? - extending the xml interface definition (with patrick); somehow connect that with documentation; create a reverse path, i.e. define layouts etc in xml Great new for internal documentation (I suppose this will be the mean to complete the http://members.ping.de:8061/ reference manual ? - more extensive support for multi media ConTeXt is probaly already the (one of the?) best tool for that (but for html :-) - more interfaces as part of the example framework (different thread, but of interest to web publishing) - (some fun projects) - some educational specific things - reorganizing my documentation tree and putting some source code on line - extending/updating manuals (i wanted to dedicate time to that earlier this year, but adapting to changes in tds / web2c took quite some time) The Context book would be the most important thing to do, I think.
