issue in the wiki

[Pablo Rodriguez]

Dear list,

modifying http://wiki.contextgarden.net/Command/hrule#Example, I added
an "\hrule height .25in".

I’m afraid that this command make all rules vanish in the final document.

The same source compiles fine with latest beta (2016.05.22 15:18) on my
laptop.

Is there anything that I’m missing or have i hit a bug?

Many thanks for your help,

Pablo

Letterspacing

[Thomas Fehige]

I'm still trying to understand some ConTeXt ways of doing things, being 
a kind of LaTeX native myself. I bought the context-fonts manual, but 
still can't figure out how to implement a macro that does the simple(?) 
following, especially item 3:

1. Make #1 uppercase [OK, in simple situations I could just type the 
uppercase letters]
2. change #1's color to xxx [not a problem]
3. apply an amount of letterspacing to the capitalized #1 that I can 
specify myself.

Maybe I'm only using the wrong search term, maybe the letterspace 
feature is well hidden in the documentation, maybe it doesn't exist: I 
simply don't know and don't see a way to find out. \stretched is not an 
answer.

Any hints appreciated.

Cheers -- Thomas

Hi Mohammad,

the stable version (from 2015.05.18 12:26) compiles the document fine.
All rules are there.

There must be something problematic besides ConTeXt itself (something
related to the generation of the .png image?).

Many thanks for your help,

Pablo

Partial \framed

[Thomas Fehige]

I'm trying to put a piece of text in a partial frame that's meant to 
look like square brackets aligned with the left and right edges of the 
textblock.

I tried to use two \framed constructions inside each other, the outer 
one with width=textwidth and negative toffset and boffset, the inner one 
with a smaller width, a fat rulethickness and the color of the 
background, expecting it to erase the outer frame where it's not needed:

\color[zier]{%

\framed[%

align=middle,

width=\textwidth,

                         toffset=-4mm,

boffset=-4mm,

strut=no,

]{%

\color[paper]{\framed[%

align=middle,

width=222mm, % i.e. \textwidth-4mm

                                 toffset=6mm,

boffset=5mm,

rulethickness=5mm

]{%

\color[zier]{\tfd \strut Here's the text that is menat to look 
important; its length/number of lines is undetermined.\strut}

}}%

}%

}%

... but it doesn't work. Apparently the inner frame is drawn before the 
outer one. Putting the wider frame inside the narrower results in 
alignment problems --  due to the overfull hbox, I presume.

Is  there a simple solution in ConTeXt that I haven't found yet, or will 
I have to try some plain TeX box magic myself?

Thanks -- Thomas

Your example is of not much use because it can’t be converted to a PDF 
(missing \starttext and empty lines).

You can use MetaPost to draw the frame/lines for the left and right borders.

\startuseMPgraphic{leftbracket}
     z[0] = (EmWidth,OverlayHeight) ;
     z[1] = (0,OverlayHeight) ;
     z[2] = (0,0) ;
     z[3] = (EmWidth,0) ;
     draw z[0]--z[1]--z[2]--z[3] withcolor \MPcolor{\overlaylinecolor} ;
\stopuseMPgraphic

\startuseMPgraphic{rightbracket}
     z[0] = (-EmWidth,OverlayHeight) ;
     z[1] = (0,OverlayHeight) ;
     z[2] = (0,0) ;
     z[3] = (-EmWidth,0) ;
     draw z[0]--z[1]--z[2]--z[3] withcolor \MPcolor{\overlaylinecolor} ;
\stopuseMPgraphic

\installleftframerenderer {bracket}{\useMPgraphic {leftbracket}}
\installrightframerenderer{bracket}{\useMPgraphic{rightbracket}}

Re: Partial \framed

[Thomas Fehige]

Thank you Wolfgang, that is exactly what I was looking for.

I apologize for the incomplete example. I have no idea, however, how all 
the empty lines got in there. They weren't there when I clicked "send", 
only when I saw it in the list.

basic fontsizes question

[Thomas Fehige]

[-- Attachment #1.1: Type: text/plain, Size: 721 bytes --]

In the fonts book I found the \definebodyfont command, but it does not 
to do what I expected. What I need (for a poster) is a set of absolute 
font sizes. I tried the code below. I put some quirks in, like the huge 
value for "a", to see if it works, but it doesn't. It just uses the 
preset proportions relative to the preceding fontsize command (in the 
example, \tfx is bigger than \tf).

\definebodyfontenvironment[palatino][24pt][

text = 24pt,

small = 22pt,

x=22pt,

scriptscript = 16pt,

xx = 16pt,

big=28pt,

a = 80pt, % 28pt

b = 40pt,

c = 50pt,

d = 50pt,

interlinespace = 3ex,

em = italic

]

\setupbodyfont[palatino,24pt]

\starttext

\tf tf\\

\tfa tfa\\

\tfb tfb\\

\tfx tfx\\

\tfx tfx

When you have only a small amount of text the use of 
\definebodyfontenvironment is overkill because you can use the 
\definedfont command to set a certain font size.

\starttext

\start \definedfont[Serif at 20pt]

\startfont[SansBoldItalic at 18pt]

Nevertheless, I prefer to keep all the font and fontsize definitions and 
tweaks together in the preamble. This poster is not the only work I'm 
planning to do in ConTeXt, and I need to learn to swim while already in 
the water ;) .

Meanwhile I found the command \definebodyfontswitch and defined switches 
like \normalsize, \scriptsize, \large, \Large etc.

But this doesn't explain why \definebodyfontenvironment did not do 
anything in my MNWE. The fonts book is not very clear on its intended use.

BTW, I have no idea how all the strange line breaks crept into my code 
sample again. It seems tabs in a html mail are converted into line 
breaks somewhere along the line. I'll stick to plain text in the future.

Cheers -- Thomas

For short texts where you want a certain style and size (e.g. a title 
page or a poster with few words) \definedfont is the recommended method, 
for larger amounts of the text (e.g. the abstract of a book) you can use 
\switchtobodyfont to change the size.

The \definebodyfontswitch creates only a command which uses 
\switchtobodyfont with a fixed number of arguments.

You put spaces before and after = which aren’t allowed there.

\definebodyfontenvironment
   [24pt]
   [         small=22pt,
               big=28pt,
                 x=22pt,
                xx=16pt,
                 a=30pt,
                 b=40pt,
                 c=50pt,
                 d=60pt,
    interlinespace=30pt,
                em=italic]

\setupbodyfont[palatino,24pt]

Re: basic fontsizes question

[Thomas Fehige]

Thank you Wolfgang, that solves the mystery. (As the poster is for a 
philosophical association, "few words" is not applicable here.)
