Re: [NTG-context] Use \unit for value and uncertainty

2016-10-31 Thread Florian Leupold 
Hello!

There does not seem to be a simple solution to using \unit with uncertainties, 
see below.

Could someone maybe point me to the relevant source code for the parser for 
\unit in MKIV? Then I would try to modify/improve the code myself.

Thanks a lot and best regards,
Florian

[NTG-context] Reduced whitespace when nesting different itemgroups

2016-10-20 Thread Florian Leupold 
Dear list,

I have noticed a strange behavior when nesting different itemgroups: The 
whitespace before the lower-level group is reduced. This does not happen when 
nesting itemgroups of the same kind. And this can somehow be circumvented by 
setting [columns, one], see MWE below.

Is this expected behavior, or a bug?

Best regards,
Florian


MWE:

\starttext

\startitemize
\item Itemize 1.
\startitemize[columns, one]
\item Itemize 1.1
\item Itemize 1.2
\stopitemize
\stopitemize

\defineitemgroup[it]
\startitemize
\item Itemize 1.
\startit
\item It 1.1 (reduced whitespace above)
\item It 1.2
\stopit
\stopitemize

\startitemize
\item Itemize 1.
\startit[columns, one]
\item It 1.1
\item It 1.2
\stopit
\stopitemize

[NTG-context] How to clone \underbar?

2016-10-19 Thread Florian Leupold 
Dear list,

how can I clone \underbar (for the purpose of changing settings for the clone 
afterwards)?

Just using \definebar to inherit \underbar’s properties does not entirely work, 
see MWE:

\definebar[myBar][underbar]
\starttext
underbar text mode: \underbar{$a^b$}\crlf
underbar math mode: $\underbar{a^b}$\crlf
myBar text mode:\myBar{$a^b$}   \crlf
myBar math mode:$\myBar{a^b}$
\stoptext

Thanks and best regards,
Florian

[NTG-context] Side effect of leftmargin for formulas on \inright

[NTG-context] Underlining formulas and units

underbar behaves weirdly when it comes to indexes, exponents, and units:

Am I doing something wrong? Is there maybe a setting to correct for this?

Okay, is this something that got fixed since May then?

Using ConTeXt online (ConTeXt  ver: 2016.05.19 13:43 MKIV current  fmt: 
2016.8.24), it also does not work.
http://live.contextgarden.net/cgi-bin/output.cgi?id=dpiqSe

That would mean I am in trouble because I am running the MacTeX version of 
ConTeXt since I could not get the standalone version to work with TeXShop.

Florian

Dear Wolfgang,

thank you for your suggestion!

However, it seems the code does not compile properly. Both, frame and tabulate 
compile without the other, but not together. The error I get is “Missing }

Could this be a bug?

Dear Aditya,

thanks, that is indeed what I wanted to achieve. I don’t know why I got hung up 
with “alternative=left”.

Best,
Florian

[NTG-context] Enumeration: chapter in counter, problem next to placefigure, and documentation issues

2016-09-04 Thread Florian Leupold 
Dear list,

I am trying to use enumerations with MKIV I am a bit at a loss when it comes to 
the documentation (see below for a few issues).

Working on a concrete example, I have come pretty close to what I want for my 
enumeration ‘theorem’:

\setupexternalfigures[location=default]
\setupenumerations[
alternative=left,
text=Theorem,
headstyle=bold,
title=no,
way=bychapter,
stopper={:},
distance=1ex,
width=fit,
style=normal,
hang=fit]
\defineenumeration[theorem]
\starttext
\chapter{First chapter}
\starttheorem
The square on the hypotenuse is equal to the sum of the squares on the other 
two sides.
\stoptheorem
\chapter{Second chapter}
\placefigure[right, none]{}{\externalfigure[mill]}
\starttheorem
The square on the hypotenuse is equal to the sum of the squares on the other 
two sides.
\stoptheorem
\stoptext

QUESTIONS:
1) I would like to prefix the theorem counter with the chapter number, such 
that the number of the second theorem becomes 2.1. Can this be done?
2) Is it possible to circumvent the misplacement of the second theorem due to 
the placed figure? Ideally, the theorem would just use the space to the left it.

Issues with the documentation:
- In “ConTeXt Commands”, it says on page 224 that \setupenumeration inherits 
from \setupcounter; but in “ConTEXt reference manual", it says on page 246 that 
\setupenumerations inherits from \setupdescriptions.
- In “ConTEXt reference manual”, the key “location” for \defineenumeration 
should probably replaced by “alternative”. Right now, all examples on page 247 
are unaffected by this setting and hence look the same.
- The wiki seems to use MKII, which makes a difference for the example on 
http://wiki.contextgarden.net/Command/enumeration, which compiles differently 
under ConTeXT online.

Thanks for your help!

Best regards,
Florian

ADDENDUM:

There is still another problem: The fixed leading space may be eaten away by a 
line break.

\definebar[ClozedBar][underbar][continue=yes, color=black]
\unexpanded\def\Clozed#1{\ClozedBar{\zwj\quad#1\quad\zwj}}

\starttext
\Clozed{\color[red]{CLOZE 1}} text text text text text text text text text text

Dear Hans,

thanks a lot for your solution!

I have added "color=black” to \definebar to prevent the bar’s color from 
changing at a line break, which happens otherwise:

\definebar[ClozedBar][underbar][continue=yes]
%\definebar[ClozedBar][underbar][continue=yes, color=black]
\unexpanded\def\Clozed#1{\ClozedBar{\zwj\quad#1\quad\zwj}}
\starttext
\Clozed{\color[red]{CLOZE 1}} text text text text text text text text text text 
text
\Clozed{\color[red]{CLOZE 2 CLOZE 2}}
\stoptext

Now the extra space is hardcoded by \quad. I guess it’s not so easy then to 
make the underbar’s width a factor times the input text width? Or, 
alternatively, an explicitly given width?

Cheers,
Florian

[NTG-context] Creating cloze texts

2016-09-02 Thread Florian Leupold 
Dear list,

I would like to create cloze texts for my students with ConTeXt.

Ideally, I would have a command \cloze[]{} with the following 
functionality:

1) \cloze{} would insert an underlined gap in the text with a width 
of (say) 1.3 times the width of solution and puts the solution on top of it 
with centered alignment. I will then color the text read if the mode is 
‘teacher’ and in white if not.
2) \cloze[]{} would do the same, but with a fixed width of the 
underline. The solution should then be flush left, maybe with a horizontal 
space of \quad.
3) The underline should allow for line breaks and hyphenation, but not such 
that only empty space is broken into the next line of left in the previous (see 
MNWE).

In this way, the student’s and teacher’s versions of the script will look 
exactly the same, except for the visible solution in the teacher’s version.

The macro \underbar does a good job in terms of line breaks and hyphenation. 
But it is "too smart" in the sense that it does not underline horizontal 
spaces. The MNWE below showcases problems with my naive attempts to achieve 
underlining:
- CLOZE 1 does not have any extra space.
- CLOZE 2 does not underline the horizontal spaces.
- CLOZE 3 does not show the underline, supposedly because the first text 
elements in it are white.
- CLOZE 4 shows that introducing fake characters is not a good idea anyways 
because the cloze is broken without any “real” solution in the first line.
- CLOZE 5 shows the same for trailing space.

MNWE:
\starttext
\input ward
\underbar{\color[red]{CLOZE 1}}
\input ward
\underbar{\quad\color[red]{CLOZE 2}\quad}
\input ward
\underbar{\color[white]{x}\quad\color[red]{CLOZE 3}\quad\color[white]{x}}
\input ward
\underbar{\color[green]{x}\quad\color[red]{CLOZE 4}\quad\color[white]{x}}
\input ward
space \underbar{\color[red]{CLOZE 5}\qquad\color[white]{x}} space
\input ward
\stoptext

I would greatly appreciate help with this problem.

Thanks so much in advance!
Florian

[NTG-context] Figure-text alignment and wrapping text more tightly

2016-09-01 Thread Florian Leupold 
Dear list,

I am interested in placing a figure on the right-hand side of the page and wrap 
text around it, see MWE below. This works mostly nicely. But I have got three 
questions:

1) Is it possible to top-align the figure with the first line of the paragraph 
to its left?

2) Is there a way to reduce the vertical gap between the first and second 
figures?

3) The keyword “low” for \placefigure seems to have an effect. But I don’t know 
why and could not find a reference to that in contextref.pdf. Is this the 
correct way to wrap text “more tightly” below the figure (compare second and 
third figures).

Thanks a lot for your input.

Best regards,
Florian


MWE:

\setupexternalfigures[order={pdf,png,jpg}, location={local,global,default}]
