[NTG-context] Wiki - question about Command/ pages which start with a space character

[garulfo]

Hi all,

Is it on purpose that 128 pages "https://wiki.contextgarden.net/Command/ 
" start with a space character ?
I didn't find an explanation in https://wiki.contextgarden.net/Command

For example, these two pages exist :
- https://wiki.contextgarden.net/Command/startbuffer
- https://wiki.contextgarden.net/Command/_startbuffer

If it is on purpose: 
- What is the purpose, and which page should contain which documentation?

If it is not: 
- Is there a way to automatically merge the content of the couple of pages, and 
to remove the "wrong" pages, or should it be done manually ?

Thanks for your help.

[NTG-context] Re: How can I do this?

[Otared Kavian]

Hi Ursula,

The reason for which you did not get the expected result is that you have « } » 
missing in your file, that is the closing brace after your italic command
« {\it » at the end of your document. 
Moreover you did not have a \stoptext in your file, and a math command « \m » 
was not written correctly. Talking of math, I personnaly prefer to enclose 
in-line math between dollar signs $, that is writing « $\exists x \in H$ » 
instead of  « \m{\exists x \in H} ».

Also the way you write your text is somewhat « incorrect » (or as Mikael 
Sundqvist would put it, « interesting »…), since in principle all the setups 
and definitions must be before the body of your document which begns with 
\starttext. Another point i sthat instead of using \par you can leave a blank 
line, which makes the document more readable. And you don’t need to break the 
lines by « hand », since ConTeXt does it in a better way.
Finally instead of 
\blackrule[color=black, height=0.10ex, width=13.50cm]
you can use just \hairline, and the thickness and color of such a \hairline can 
be adjusted by 
\setupthinrules[rulethickness=4pt,color=darkgreen]
(for instance), which should be put before \starttext.

Best regards: Otared

\inframed did make a difference, indeed. I'll check if I can obtain
the spacing I need. Thanks.

\startparagraph starts a paragraph environment. If you overwrite it by
defining another, the behaviour is undefined.

First try to give your textbackground a different name.

Hi Uschi,
unfortunately you also forgot the source code.

I’m not sure if the examples in the wiki are good – the combination with 
\startnarrower might be a problem.

Maybe setting the width helps (e.g. to \makeupwidth).

[NTG-context] Re: Colored Paragraph

[Henning Hraban Ramm]

Hi Uschi,
unfortunately you also forgot the source code.

I’m not sure if the examples in the wiki are good – the combination with 
\startnarrower might be a problem.


Maybe setting the width helps (e.g. to \makeupwidth).

[NTG-context] textbackground spacing offset

[Marco Patzer]

Hi!

I'm having problems getting the textbackground spacing offset to work.
Example:

\setupframedtext
  [offset=overlay,
   width=max,
   depthcorrection=off]

\setuptextbackground
  [location=paragraph,
   %% offset=overlay,   %% does nothing
   %% backgroundoffset=overlay, %% does nothing
   %% depthcorrection=off,  %% does nothing
   %% topoffset=3mm,%% works, but only for positive values
   background=,
   frame=on]

\starttext
  \startframedtext
\framed{Foo}
  \stopframedtext
  \starttextbackground
\framed{Foo}
  \stoptextbackground
\stoptext

How do it get the same spacing as in the framedtext case? The
textbackground has a small gap between the inner and outer frame at
the top and a larger gab at the bottom. I'm not concerned with
horizontal spacing here.

Marco

As an example, see this article that I had written years ago:

https://www.tug.org/pracjourn/2006-4/mahajan/

The solution environment there is similar to what you want. Most of the code 
there should still work with minor changes.

If you don’t need an enumeration, then don’t use one.

Did you try text backgrounds?
https://wiki.contextgarden.net/TextBackground

And then use the plethora of \framed options.

Re: [NTG-context] Floating Figure in framed-environment

Oliver Sieber via ntg-context schrieb am 19.10.2022 um 11:31:

Dear ConTeXt Users

I am relatively new to context and I am suffering with a problem with the 
framed environment.

I want to use a framed textbox for Definitions in my script. I also want to use 
floating figures.  But this does not work and I haven’t found out why. Maybe I 
totally use it the wrong way. I would appreciate if someone could help me or 
has a tipp.

Here is an example code, where the figure does not behave as expected, i.e. the 
figure is behind the text:

You have to use the textbackground mechanism to create a block of text 
where floats work as expected.

[NTG-context] textbackground for text of different size

Dear List,

the red highlight block in the following example is not covering the two
40pt characters:

\definetextbackground[important][frame=no,background=color,backgroundcolor=red]
\starttext
abc\important{123{\switchtobodyfont[40pt]45}xy}z

Is there an option that fixes this?

Re: [NTG-context] numbered exercises

[Henning Hraban Ramm via ntg-context]

Here’s what I have now (result attached):

\define[1]\ÜbungNrCmd{\inmargin{\offset[y=3em]{\rotate[rotation=90]{\SectionFont
 #1
  
\defineenumeration[Übung][
  text=Übung,
  title=yes,
  titleleft=,
  titleright=,
  titledistance=-1em,
  titlestyle=\SectionFont,
  %numberstyle=\SectionFont,
  numbercommand=\ÜbungNrCmd,
  way=bytext,
  margin=1em,
  before={\blank[2*line]},
]


Now I’d like to have a vertical line beside the text, starting below the title.

And because I want to use the “sketchy“ lines we discussed a while ago (I 
needed them for the same book), it must be a MetaPost-drawn line.

What’s the right approach? Overlay? Textbackground?

In the following MWE for a textbackground the parameter 
backgroundoffset has the expected effect. But for positive values 
only. A backgroundoffset=-10pt has no visible effect.
But the real problem is the parameter frameoffset. No effect at all, 
whatever frameoffset= is set to.


The textbackground mechanism uses MetaPost to draw the background, lines 
etc.


Not all options are available for each background, e.g. frameoffset 
works by default only for side lines.

I have updated and now it works. Thank you very much for all your efforts.

Now let's come to my second problem: the sidebar. Proudly, I present to you my
first MWE:

\definetyping[CPP] 
   [before=\startsidebar,
 after=\stopsidebar]

\starttext

\samplefile{ward}

\startCPP
#include 

int main(void)
{
 printf("hello, world\n");
}
\stopCPP

\samplefile{weisman}

\stoptext

Can you see that there is an additional line before and after the code?
How can I get rid of these?

I greatly appreciate your help.

Thanks,
Johann

You have to use the textbackground environment with a custom background
to draw the line, the sidebar environment doesn't work because the code
blocks forces a line break at the begin and end.

You can look at Adityas blog for a example to create such a background:

Hello Wolfgang,

let's take your code as a MWE. I compiled exactly your code and there is a line
at the end. I attached my compiled PDF.

I compiled it using "context test" where the file name is "test.tex" with
exactly your content.

I am using the latest version from the Arch Linux Repo, `context --version`
gives:

mtx-context | ConTeXt Process Management 1.03
mtx-context |
mtx-context | main context file: /usr/share/texmf-
dist/tex/context/base/mkiv/context.mkiv
mtx-context | current version: 2020.03.10 14:44
mtx-context | main context file: /usr/share/texmf-
dist/tex/context/base/mkiv/context.mkxl
mtx-context | current version: 2020.03.10 14:44

So probably I should upgrade..

Greetings,
Johann

Ah, sorry again. I use

\usemodule[Scite]

at the begin of the document. Removing this helps. But I need it for the C and
Cpp pretty printer. So do you know what's going on with Scite module?

Sorry for confusing \starttext with \starttyping.

@Wolfgang this is exactly what I mean. It doesn't work. There is an extra line
at the end. If you remove [option=XML] it works. So what is going wrong?

Again, a MWE help to understand what is going wrong.


\definetextbackground[code][background=color, backgroundcolor=lightgray,
frame=off, location=paragraph]

\setuptyping[before={\startbackground[code]}, after={\stopbackground}]

\definetyping[XMLtyping]

I didn't want to copy paste it :D Just add [option=XML] to \starttext like this:

\definetextbackground[code][background=color, backgroundcolor=lightgray,
frame=off, location=paragraph]

\setuptyping[before={\startbackground[code]}, after={\stopbackground}]

\starttext[option=XML]
\starttyping
This is some code
a second line
\stoptyping
\stoptext

When I use \definetyping[Mytyping][option=XML] and then use \startMytyping ...

Okay so first sorry that the example missed the \starttext ... \stoptext. Won't
happen again.

So unfortunately my MWE was too minimal. Actually this works:

\definetextbackground[code][background=color, backgroundcolor=lightgray,
frame=off, location=paragraph]

\setuptyping[before={\startbackground[code]}, after={\stopbackground}]

\starttext
\starttyping
This is some code
a second line
\stoptyping
\stoptext

However, I use pretty printing. When you add [option=XML] to \starttext it
breaks.

Why?


Do you have a example.

[NTG-context] Vertical space when surrounding with textbackground

[Johann Birnick]

Hi there,

in my document(s) I have enumerations (created with \defineenumeration) and
"typing"s (created with \definetyping) and I need to give a specific layout to
them. In particular, I want to add textbackground (created with
\definetextbackground) and sometimes a sidebar (created with \definesidebar) to
them.

However, when I surround for example my typing with a textbackground like this

\starttextbackground[code]
\startCpp
...
\stopCpp
\stoptextbackground

or by putting the textbackground commands in "before=" and "after=" of my
typing, then there will be an additional empty line at the end of the typing.

Same with the enumerations and when I surround it with a sidebar instead of a
textbackground. Often there is even an additional line / additional space before
the typing/enumeration.

How to surround such things properly? I just want a background to these and a
sidebar. No addition spacing / empty lines.

I would greatly appreciate your help.

Thank you,
Johann

Hi Fabrice,

Maybe you can play with different settings of your textbackground, as in

\definetextbackground[fondpaille]
[background=color,
backgroundcolor=fondpaille,
frame=off,
location=paragraph, % or: text, always, paragraph
backgroundoffset=4pt] % change the value here


It's a float feature which can be disabled.

\definetextbackground[fondpaille]
[background=color,

Side floats don't work in frames, use the textbackground environment to

Wolfgang or whoelse,
when would you advise to use textbackgrounds and when bars? E.g. if I need a 
“marker” highlighting.

Hello,

it seems that bar (even with option 'continue=yes') is not rendered in place of 
'~' within math. See the sample:


\definebar[MyBar][color=green,rulethickness=2.8,order=background,offset=1.5,continue=yes]

\starttext
   1 + 2 = \startbar[MyBar]3~kN\stopbar % OK

   $1 + 2 = \startbar[MyBar]3~\text{kN}\stopbar$ % No background behind space

   $1 + 2 = 
\inframed[frame=off,background=color,backgroundcolor=green,offset=0pt,]{3~\text{kN}}$
 % OK!
\stoptext


In the sample 'kN' is a unit, which should be separated by space from the 
result (here: 3);
I am used to put the unit into the math environment and enclose it into 
\text{...}.

Is there a way to make the bar be rendered in places of blanks within math, too 
(like if it was inside $ ... $ - as the first line of the sample)?

- Note that I can use \inframed to get background filled fully, but anyway - how about 
usage of "bar" for this?


Use a textbackground to highlight parts of your text.

\definetextbackground
  [Highlight]
  [frame=off,
   background=color,
   backgroundcolor=yellow]

\starttext

\m{1 + 2 = \unit{3 kilo newton}}

\m{1 + 2 = \Highlight{\unit{3 kilo newton}}}

\stoptext

If an article contains several \starttyping ... \stoptyping examples with a

It’s the same with MkIV and LMTX.

Can you show the typing and textbackground settings.

You can't use "location=paragraph" because the argument of the \setlayer 
command is a simple horizontal box which doesn't create a paragraph 
unless you us additional command which create a paragraph.



\definelayer[testlayer]
\setlayer[testlayer][x=1cm,y=3cm]{%

Simpler method:

or

I have found in similar situations sometimes the easiest fix is to set the
backgroundcolor of footnotes to white (or your page colour if different).

Re: [NTG-context] Strange pagebreaks in LMTX

[Otared Kavian]

Hi Aditya,

Thank you for your reply and for the link to your article: your explanations 
are cristal clear and the solution for me is to use what you explain.

There is only one issue remaining, when using your code, that is:

\definetextbackground
  [leftbartext]
  [
location=paragraph,
mp=mpos:region:leftbar,
width=broad,
frame=off,
framecolor=darkred,
rulethickness=.5pt,
leftoffset=2ex,
%rightoffset=2.25ex,
%topoffset=2.25ex,
%bottomoffset=2.25ex,
background=color,
backgroundcolor=white,
  ]

\startuseMPgraphic{mpos:region:leftbar}
  draw_multi_pars;
  draw_multi_side;
\stopuseMPgraphic

then when there is a footnote the leftbartext runs into the footnote, between 
the number and the footnote itself, and the result is not nice. I did not find 
a way to push the footnote and its number a little to the right, or the 
leftbartext to the left.

Best regards: OK

Re: [NTG-context] Strange pagebreaks in LMTX

[Otared Kavian]

Hi Wolfgang,

Thanks for your answer. I tried Hans' suggestion to use \textbackground instead 
of background: indeed it solves the problem of incorrect page breaks, but it 
seems that \setuptextbackground « leftframe=on » is not honoured, that is one 
cannot say for instance:

\setuptextbackground[frame=off,leftframe=on]

while using \background this would be possible. 
The other issue, as you pointed out is the way the end of \textbackground can 
be controlled (even though for my case it is not an issue). 

The \sidebar mechanism in order to have a vertical line on the left of each 
exercise does not work properly neither, because it is difficult to control 
precisely where it ends.

Best regards: OK

Re: [NTG-context] startnarrower and framed?

[Jon Wong]

Hi all,

I’m so so sorry for yet another message in this thread. I’ve solved it, but 
still don’t quite understand why it works. I post the solution here so that 
nobody has to spend any time crafting the solution. But I still have 1 key 
question.

Key question: Why does \setwhitespace[line] prevent \blank[-0.5em] from working 
after a \framed?

(Ok. I better sleep before I pollute the mailing list further.)

Apparent Solution:

\usecolors[xwi]
\setupwhitespace[line]

\starttext
\definetextbackground[secondary][
  location=always,
  background=color,
  backgroundcolor=lightgray,
  leftoffset=.5\bodyfontsize,
  rightoffset=.5\bodyfontsize,
  topoffset=.5\bodyfontsize,
  bottomoffset=.5\bodyfontsize,
  frame=off,]

\input knuth

{

\blank[line]

\setupwhitespace[none]

\startnarrower
  \dontleavehmode\framed[
width=local, corner=03, background=color, backgroundcolor=cyan,
frame=off
  ]{My header!}

  \blank[-0.5em]

  \startsecondary
  {

  \setupwhitespace[line]

\input knuth

  }
  \stopsecondary
\stopnarrower

}

\input knuth
\stoptext

Re: [NTG-context] startnarrower and framed?

[Jon Wong]

Hi all,

Ok, last message in this topic, I promise. I’ve crafted a MWE.

If I \setupwhitespace[line], the \blank[-0.5em] stops working. I’m sure I need 
to revise my TeX notes. For now, can somebody give me a little encouragement 
and tell me the answer? :-P

\usecolors[xwi]
% \setupwhitespace[line]

\starttext
\definetextbackground[secondary][
  location=always,
  background=color,
  backgroundcolor=lightgray,
  leftoffset=.5\bodyfontsize,
  rightoffset=.5\bodyfontsize,
  topoffset=.5\bodyfontsize,
  bottomoffset=.5\bodyfontsize,
  frame=off,]

\input knuth

\startnarrower
  \dontleavehmode\framed[
width=local, corner=03, background=color, backgroundcolor=cyan,
frame=off
  ]{My header!}

  \blank[-0.5em]

  \startsecondary
\input knuth
  \stopsecondary
\stopnarrower

\input knuth
\stoptext

Jon

Re: [NTG-context] startnarrower and framed?

[Jon Wong]

Hi all,

Ah, found the solution in TextBackground. At here: 
https://www.contextgarden.net/TextBackground 
<https://www.contextgarden.net/TextBackground>

Can I have a 2-segment (2 vboxes) TextBackground (presumably with 2 
TextBackgrounds, zero vspace between them)?

For the top segment, I want rounded corners only for top corners (corner=03 
with \framed).

Seems I really should dig into MetaFun and TextBackground. Looks really fun and 
useful.

Sorry for the noise. Am a little carried away exploring the Garden. :-P

Jon

Re: [NTG-context] Captions with background

[Hans Hagen]

On 8/3/2019 5:22 PM, Henning Hraban Ramm wrote:

Hi,

in my books I typeset captions onto full page images, therefore I need a 
background; in the attached example it’s just a white box, usually I use a 
MetaPost shadow (some of you helped me with that a few years ago, current code 
see https://wiki.contextgarden.net/Drop_shadows).

Now, the background should just enclose the text, not more. Since I don’t know 
how long the caption will be (I use the whole setup in a macro), I need a \vbox 
within \setlayer, but that always uses the full \textwidth, regardless of width 
settings of \framed.

If the caption is short, the box should be minimal. Is this possible?


Even better would be a textbackground just behind the text lines.

Unfortunately my MP foo is not up to the task, the rectangular shadow was hard 
enough, but I’d try.
There’s an example in details.pdf, but I don’t understand how I could 
manipulate the path around the text (not: paragraph).


The example shows another problem: If you run it with --mode=arrange, the bleed 
is cut off.
Is this a matter of settings or a bug?


Greetlings, Hraban

[NTG-context] Captions with background

[Henning Hraban Ramm]

Hi,

in my books I typeset captions onto full page images, therefore I need a 
background; in the attached example it’s just a white box, usually I use a 
MetaPost shadow (some of you helped me with that a few years ago, current code 
see https://wiki.contextgarden.net/Drop_shadows).

Now, the background should just enclose the text, not more. Since I don’t know 
how long the caption will be (I use the whole setup in a macro), I need a \vbox 
within \setlayer, but that always uses the full \textwidth, regardless of width 
settings of \framed.

If the caption is short, the box should be minimal. Is this possible?


Even better would be a textbackground just behind the text lines.

Unfortunately my MP foo is not up to the task, the rectangular shadow was hard 
enough, but I’d try.
There’s an example in details.pdf, but I don’t understand how I could 
manipulate the path around the text (not: paragraph).


The example shows another problem: If you run it with --mode=arrange, the bleed 
is cut off.
Is this a matter of settings or a bug?


Greetlings, Hraban

It will take some time to understand everything in "mp-abck.mpiv" but it
will sure be very interesting.

Use backgrounds or textbackgrounds.

Thank you but I still can't achieve what I want to do whith this
command.

I try to make something similar to the frames in the
"mkiv-publications.pdf" manual (page 6 or 22 for a bibliography for
examples).
I suppose Hans Hagen made use of metafun to do it but I encounter some
problems with 'textbackgrounds'.

In this minimal example, the frame doesn't appear (or if i set
[frame=on,leftframe=off] all the frame is rendered) and the left and
right offsets are not took into account.


textbackground uses metapost for ALL backgrounds and the default metapost 
code to draw the background (draw_multi_pars, defined in mp-abck.mkiv) 
doesn't handle individual frames. So, you have to write your own metapost 
code to draw the side bar.


Another option for simple backgrounds is to use `\definebackground` 
instead of `definetextbackground`. The background mechanism doesn't have 
too many options, but does honor leftframe and rightframe by default.

For me it’s still fine with 2017.07.30 19:30.

Hi Thomas,

I can confirm the bug. It works fine with ConTeXt from TeX Live 2017,
but not with latest beta (that I get to work) from 2017.10.29 15:44.

[NTG-context] Textbackground offset with multi-col paragraphs

[Thomas Floeren]

Hi,

I noticed that with one of the recent betas the right offset of my 
textbackgrounds doesn’t work properly anymore when the textbackground contains 
a multi-column “paragraph”.

A minimal:

\defineparagraphs [TestPar][n=2, distance=7mm]
\setupparagraphs [TestPar][1][width=2em]

\definetextbackground [CB][
location=paragraph,
backgroundcolor=gray,
leftoffset=.3em,
rightoffset=.3em,
topoffset=.3em,
bottomoffset=.3em,
frame=off
]

\starttext

\starttextbackground [CB]
\dorecurse {40} {a b c } 
\stoptextbackground

text

\starttextbackground [CB]
\startTestPar
img
\TestPar
\dorecurse {40} {a b c } 
\stopTestPar
\stoptextbackground

\stoptext


The first box is OK and as expected. But with the second one (containing a 
“paragraph”) the right offset gets miscalculated, so that the text runs into 
the edge of the background.

With a beta from July or so the behavior was still OK.

Thanks for any advice,
best,

By default, the highlighting is done using the bars mechanism. It works 
for simple cases but fails with math mode (the spaces are not covered). 
One option is to highlight using the textbackground mechanism:


\definetextbackground[texthighlight]
 [
   background=color,
   backgroundcolor=gray,
   frame=off,
 ]

\define[1]\texthighlight{\starttexthighlight#1\stoptexthighlight}

\usemodule[vim]
\definevimtyping[python][syntax=python, escape=on, 
highlightcommand=\texthighlight]

\starttext

\startpython[highlight=3]
for x in 1:n
   print(x)
# Returns \m{\sum_{i=1}^{n}i \in F \int_i f}
for x in 1:n
   print(x)
\stoppython
\stoptext

Thank you, this works much better (critic on high level: the sum symbol is
higher than the highlight box, relevant on fractions).


Another option (slightly better visually, but increases the interline 
distance)


\defineframed[texthighlight]
[
  background=color,
  backgroundcolor=gray,
  frame=off,
  location=middle,
]

\usemodule[vim]
\definevimtyping[python][syntax=python, escape=on,
highlightcommand=\dontleavehmode\texthighlight]

\starttext

\startpython[highlight=3]
for x in 1:n
  print(x)
# Returns \m{\sum_{i=1}^{n}i \in F \int_i f}
for x in 1:n
  print(x)
\stoppython
\stoptext

By default, the highlighting is done using the bars mechanism. It works 
for simple cases but fails with math mode (the spaces are not covered). 
One option is to highlight using the textbackground mechanism:

\definetextbackground[texthighlight]
 [
   background=color,
   backgroundcolor=gray,
   frame=off,
 ]

\define[1]\texthighlight{\starttexthighlight#1\stoptexthighlight}

\usemodule[vim]
\definevimtyping[python][syntax=python, escape=on, 
highlightcommand=\texthighlight]

\starttext

\startpython[highlight=3]
for x in 1:n
   print(x)
# Returns \m{\sum_{i=1}^{n}i \in F \int_i f}
for x in 1:n
   print(x)
\stoppython
\stoptext

The spacing in math mode is bad. What is happening is the following. To 
make sure that spaces are obeyed in the code listing, I set (a modified 
version of) \activatespacehandler{on}, so the output that you get is the 
following:

{\obeyspaces
  \def\obeyedspace{\hskip\interwordspace\relax}
\m{\sum_{i=1}^{n}i \in F \int_i f}}

The simplest way to fix this is to define a new command:

\define[1]\MATH{\bgroup\activatespacehandler{off}\m{\rescan{#1}}\egroup}


Why not just this?

\def\obeyedspace{\ifmmode\else\hskip\interwordspace\relax\fi}


That's a good suggestion and will be easier to incorporate in t-vim.

Hi,

I have two questions with the vim module.

1. I want to use the math mode inside the code. I've seen the escape option,
e.g. here [1], but this seems to work only with comments. Is there a
possibility to use it directly in the code, too?


Short answer. No.

Long answer. t-vim relies on vim to syntax highlight the code. Since the
code is not valid python, the default python syntax highlighting will not
work. In principle, it is possible to write a vim syntax highlighting
script for a derivative of python where math terms are allowed, but that
requires a lot of work for each language. The whole point of t-vim module
was that I am lazy and don't want to write the parser for each language
:-)


I've invested some time and rewrote parts of the vimscript file of t-vim.
Now one or more escapechars can be defined, that helps vim to not interpret
the text:


I'll look at this later


Another point I saw is, that highlight together with TeX-code is not really 
usable:
```
\usemodule[vim]
\definevimtyping[python][syntax=python, escape=on]

\starttext
\startpython[highlight=1]
# Returns \m{\sum_{i=1}^{n}i \in F \int_i f}
\stoppython
\stoptext
```


By default, the highlighting is done using the bars mechanism. It works 
for simple cases but fails with math mode (the spaces are not covered). 
One option is to highlight using the textbackground mechanism:


\definetextbackground[texthighlight]
[
  background=color,
  backgroundcolor=gray,
  frame=off,

\define[1]\texthighlight{\starttexthighlight#1\stoptexthighlight}

\usemodule[vim]
\definevimtyping[python][syntax=python, escape=on, 
highlightcommand=\texthighlight]

\starttext

\startpython[highlight=3]
for x in 1:n
  print(x)
# Returns \m{\sum_{i=1}^{n}i \in F \int_i f}
for x in 1:n
  print(x)
\stoppython
\stoptext

\define[1]\MATH{\bgroup\activatespacehandler{off}\m{\rescan{#1}}\egroup}

and use \MATH{} instead of \m{}.

I'll test this is a bit, and if the solution is robust, then I will map 
\m{...} to something equivalent to the above in the t-vim environments.

That indeed solves the problem of the textbackground extended over footnotes. 
Is that anywhere documented? I did not find that anywhere. And what exactly 
does that command do?

Would it not be a good idea to add this as an option in the definition of a 
textbackground?

Here is a minimal:

Is this a bug?

Thank you, Hans, this works absolutely great!

Two little questions:

I have set it now globally for _all_ floats as \setupfloats[freeregion=no].
At a first glance it doesn’t seem to cause any issues.
Is there any pitfall when setting it globally, which I might not be aware?

Is 'freeregion=no' an option that is meant to stay, or is it a workaround for 
the recent betas?


it will stay (being a feature)

I think i fixed it (no upload yet) but this kind of tricky things

Re: [NTG-context] Overlays as background in textbackground

Here is a trick (due to Hans, of course) to produce a watermark image.
You can play with the idea in order to produce your own effect.

Re: [NTG-context] Overlays as background in textbackground

[Meer, Hans van der]

This code from three years back ia a reply to a question of placing an overlay 
background. Because the cow is very black I am curious if the \externalfigure 
can have a paramter to change the alpha of the cow, making it more transparent. 
By the way, it is not out of curiosity only. If possible it would forego the 
need to make separate pictures of different transparency beforehand.

Re: [NTG-context] Is there “toffset” option for \setupbackgrounds in context

[Wolfgang Schuster]

Bou Salim <mailto:salimcol...@gmail.com>
26. Februar 2016 um 12:44
I'm trying to learn `context`, and I'm satisfied with their capacities.

I read in contextgarden 
<http://wiki.contextgarden.net/Command/setupbackgrounds> that options 
of `\setupbackgrounds` inherit from `\setupframed`, but if I setup 
`toffset=5mm` for 
 `\setupbackgrounds[text][text][frame=on,toffset=5mm]` I have no effect?


With `frameoffset` you can modify the four directions but how about a 
single direction?
The background mechanism for the text areas supports only a fraction of 
the normal framed options but you can do a lot when you use Metapost to 
draw the background.


\startuniqueMPgraphic{TextBackground}
path p ; p := unitsquare xscaled OverlayWidth yscaled OverlayHeight ;
draw p topenlarged 5mm ;
setbounds currentpicture to OverlayBox ;
\stopuniqueMPgraphic

\defineoverlay[TextBackground][\uniqueMPgraphic{TextBackground}]

\setuppapersize[A4]
\setuppagenumbering[state=none]

\setupbackgrounds[text][text][background=TextBackground]

\starttext

\input knuth

\stoptext

BTW: It’s rude to crosspost without mentioning this 
(http://tex.stackexchange.com/questions/296037/is-there-toffset-option-for-setupbackgrounds-in-context)

[NTG-context] textbackground

[Alan BRASLAU]

Hello,

For a multilingual document, alternating one language or another, not
necessarily a bilingual, translated text, I thought about using
textbackground to set-off paragraphs. This technique could also apply
to a single language text having multiple levels of information,
perhaps statements followed by discussion, etc.

A problem appears with respect to footnotes that I do not know how to
handle. If the backgrounded text goes across pages placing footnotes,
then the footnote also gets the background. This is incorrect, perhaps
a bug.

Second problem, if a footnote of a backgrounded text gets placed on a
following page, then it may not get a background. (It is not clear to me
whether it would be correct for footnotes to get the background or
not.) Of course, a solution to this secondary problem might be
before={\startlocalfootnotes},
after={\placelocalfootnotes\stoplocalfootnotes},
although such a solution would postpone backgrounded footnotes to the
end of the backgrounded text.

Alan

[NTG-context] textbackground within framedtext

[Christoph Reller]

Hi,

How can I use textbackground within framedtext. In the following MWE, the
background extends beyond the frame of framedtext. Do I have to use a
different mechanism?

\definetextbackground[bg][
  background=color,
  backgroundcolor=yellow,
  frame=off]

\starttext

\startframedtext
  Before \par
  \starttextbackground[bg]
  \input knuth
  \stoptextbackground \par
  After
\stopframedtext

\input tufte \par
\starttextbackground[bg]
\dorecurse{2}{\input knuth \par}
\stoptextbackground
\input tufte

\stoptext

Any feedback is welcome,

Regards,
Christoph

The command \startnamedsection[chapter] is the same as using \startchapter in 
your
document, the only difference is that you use the header-type as argument in 
the first
case while in the second case the head-type is part of the command name.

When you print your table of contents with the \placecontent or \completecontent
commands ConTeXt uses only headers which are in the list for the “content” list.
To print additional headers which are defined with \definehead in your document
you can either use \placelist[chapter,MYHEADER,section,…] instead of 
\placecontent
or you extend the list for “content” with 
\setupcombinedlist[content][list={chapter,MYHEADER,…}]
or \placecontent[list={chapter,MYHEADER,…}]

You have to add „location=paragraph” to the textbackground setup.

\definetextbackground
  [ChapterFrame]
  [frame=off,
   background=color,
   backgroundcolor=green,
   backgroundoffset=1ex,
   location=paragraph] % default: location=text

\definehead [Framed][chapter]
\definehead [Frameless] [chapter]

\setuphead
  [Frameless]
  [before={\blank[2*line]}]

\setuphead
  [Framed]
  [page=no,
   before=,
   beforesection={\page\blank[2*line]\starttextbackground[ChapterFrame]},
   aftersection=\stoptextbackground]

\starttext

\startnamedsection[Frameless][title=Chapter without frame]

\input knuth

\stopnamedsection

\startnamedsection[Framed][title=Chapter with frame]

\input knuth

\stopnamedsection

\stoptext

[NTG-context] TOC with Grey background for pages belonging to last section of every chapter

[Keith J. Schultz]

Hi Wolgang,

I noticed that \startnamedsection does not add it to the TOC
how would one go about having these „namedsections“ added to the TOC.

regards
Keith.

Re: [NTG-context] Framed text and page breaks

[Aditya Mahajan]

If you just want to reduce the width of paragraphs, use the narrower 
environment. If you also want frames or background colors that break 
across page, use the background environment. If you want floats and 
parshape to also work, use the textbackground environment.

I've been struggling today with trying to change paragraph width of selected 
paragraphs within the body text of a novel I'm typesetting. I thought that 
the way to do this would be by framing the text that I would like to reduce 
the paragraph width off.  However the framed text doesn't seem to honour page 
breaks and just seems to disappear off the page bottom.  Also the framed text 
starts on a new page which I do not want to happen.


Any suggestions on how I may go about solving this problem?

Here is an example tex file which shows these effects:
\definepapersize[book][width=5.06in,height=7.81in]

\setuppapersize [book][]

\setuplayout 
[width=middle,backspace=12.5mm,cutspace=12.5mm,height=middle,topspace=12.7mm,bottomspace=12.7mm]


\starttext

\dorecurse{2}{\input ward \blank}

\midaligned

\framed[frame=off,width=5cm,align={width,nothyphenated,verytolerant,stretch},before=\blank]{\dorecurse{4}{\input 
ward \blank}}


\dorecurse{2}{\input ward \blank}

\stoptext
