I am getting an unexpected results with framedtexts.Why is the second "centered" not centered?

\starttext
\startframedtext[left][frame=on,offset=0pt,width=broad]
left\hfill
\stopframedtext
\startframedtext[middle][frame=on,offset=0pt,width=broad]
\hfil centered\hfil
\stopframedtext
\startframedtext[middle][frame=on,offset=0pt,width=broad]
\hfill centered\hfill
\stopframedtext
\startframedtext[right][frame=on,offset=0pt,width=broad]
\hfill right
\stopframedtext
\startframedtext[none][frame=on,offset=0pt,width=broad]
none
\stopframedtext
\stoptext

One has \hfil with one l and the other has \hfill with two l:s. \hfil
with one l seems to produce centering, while \hfill with two l:s makes
the text end up on the right.

Don't know if this is a feature or a bug, but this is the reason to
why those lines differ.

Indeed, but that is just what puzzles me and why I posted my question.
\hfill is stronger than \hfil and thus it seems all the more strange that the left and right \hfill do not produce the same centering as the \hfil's do.

Re: framedtext

Would it not be better to use ConTeXt alignment, rather than the TeX
primitives \hfil and \hfill?

\starttext

\startframedtext[left][frame=on,offset=0pt,width=broad,align=flushleft]
left
\stopframedtext

\startframedtext[middle][frame=on,offset=0pt,width=broad,align=middle]
centered
\stopframedtext

\startframedtext[right][frame=on,offset=0pt,width=broad,align=flushright]
right
\stopframedtext

\stoptext

Could be of course. But the question is: from where the counterintuitive behavioud of \hfil and \hfil?
It is my nature to be not satisfied until I know ;-)

because internally the framed align can inject \hfil \hfill \hss or 
whatever was decided best ... it's already complex enough to write 
macros like \framed that adapt to all cases users throw at it so the 
options (like align) are there for a reason

if you don't want that you need to wrap your stuff in a box in which 
case you can do inside that box what you like

Hans

(you can use \showmakeup to see what is in a \framed box)

It's easy to explain on the following example.

%%%% begin example
\starttext

\hfil Text\hfil

\hfill Text\hfill

\stoptext
%%%% end example

At the end of a paragraph TeX removes the last skip and inserts the 
\parskipfill [1] value which is by default "0pt plus 1fil".

For the first text line this results in the expected output but not for 
the second line because the inserted "fil" is smaller than the needed 
"fill". You can check this when you change the \parskipfill 
stretchability from fil to fill:

%%%% begin example
\starttext

\hfill Text\hfill

\start \parfillskip = 0pt plus 1 fill
     \hfill Text\hfill \par
\stop

\stoptext
%%%% end example

framedtext

[Hans van der Meer]

I experience the following behaviour of framedtext in relation to  
inright and inleft.
With \startframedtext[offset=value] the positioning of left and right  
margin inserts shifts with the size of 'value'.

The next example shows the shift to the right of L2 and R2 (both mkii  
and mkiv). Change the offset to see the margin notes L2/R2 shift.
\starttext
\showframe[text,margin,edge]
ABC
\inright{\framed[width=10mm,height=5mm]{R1}}
\inleft{\framed[width=10mm,height=5mm]{L1}}
\startframedtext[offset=2cm]
XYZ
\inright{\framed[width=10mm,height=5mm]{R2}}
\inleft{\framed[width=10mm,height=5mm]{L2}}
\stopframedtext
\stoptext

Pictured:
..L1.|...................|.R1
.....|.L2................|.....R2
.....|...................|
.....^...................^
^ = frame lines of showpage

I wonder if this is correct behaviour. The margins are imho fixed  
areas, defined as the areas on the left/right of the textframe. One  
would expect the margin texts put just there, not influenced by  
something that happens to be placed in the text.
Or am I amiss?

indeed ... inleft and inright use vadjust and that is somewhat special

i will come up with an alternative in mkiv

maybe \margintitle{...} works ok (delays till a paragraph)
