Centering a defined text frame

Centering a defined text frame

[Bart C. Wise]

I'm trying to have a centered text frame.  There are two examples in the code 
below.
1) This one works.  It uses a text frame that is in line in the code.
2) This one does not work! It's using a defined text frame and flushes the text 
frame to the left.  How do I fix this?

Thanks,
Bart

\defineframedtext[CenteredText][width=fit]

\starttext

% This one works!
\startalignment[center]
\dontleavehmode
\framedtext[width=fit]{
    \startlines
    The quick brown fox jumps over the lazy dog.
    \stoplines
}
\stopalignment

% This one fails!
\startalignment[center]
\dontleavehmode
\startCenteredText
    \startlines
    The quick brown fox jumps over the lazy dog.
    \stoplines
\stopCenteredText

\stoptext

In analogy to \framedtext after a define of a framedtext I expect  
that that you should use \CenteredText{...}
And indeed.

\defineframedtext[CenteredText][width=fit]
% This one fails!
\startalignment[center]
\dontleavehmode
\CenteredText{
     \startlines
     The quick brown fox jumps over the lazy dog.
     \stoplines}
%\stopCenteredText

Oh, I feel stupid.  I think I need some more sleep.  Thanks for the tip.

\defineframedtext[CenteredText][width=fit,location=middle]

\starttext

\startCenteredText
   \startlines
   The quick brown fox jumps over the lazy dog.
   \stoplines
\stopCenteredText

\stoptext

Thanks Wolfgang.

Is there a way to pass in my own defined parameters to such a function?

I would like to be able to do something similar to the following:

\startCenteredText[myownparm="This is a test"]
   \startlines
	My own parm is: \myownparm
   \stoplines
\stopCenteredText

Bart

Not with framedtext but you define your environment with a optional argument.

ConTeXt has the command \definestartstop but it did not help in your case,
something like LaTeXs \newenvironment, I wrote a simple version below.

\unprotect

\def\????ev{@@@@ev}

\def\environmentparameter#1%
  {\csname\????ev\currentenvironment#1\endcsname}

\def\defineenvironment
  {\dodoubleempty\dodefineenvironment}

\def\dodefineenvironment[#1][#2]%
  {\getparameters
     [\????ev#1]
     [\c!before=,
      \c!after=,
      #2]%
   \setvalue{\e!start#1}{\dodoubleempty\dostartenvironment[#1]}%
   \setvalue{\e!stop #1}{\dostopenvironment}}

\def\setupenvironment
  {\dodoubleargument\dosetupenvironment}

\def\dosetupenvironment[#1][#2]%
  {\getparameters[\????ev#1][#2]}

\def\dostartenvironment[#1][#2]%
  {\bgroup
   \edef\currentenvironment{#1}%
   \ifsecondargument
     \setupenvironment[\currentenvironment][#2]%
   \fi
   \environmentparameter\c!before}

\def\dostopenvironment
  {\environmentparameter\c!after
   \egroup}

\protect

\defineframedtext
  [CenteredTextFrame]
  [width=fit,
   location=middle]

\defineenvironment
  [CenteredText]
  [before=\startCenteredTextFrame\startlines,
   after=\stoplines\stopCenteredTextFrame]

\starttext

\startCenteredText[text={This is a test}]
My own parm is: \environmentparameter{text}
\stopCenteredText

\stoptext

Here is one that did exactly you wrote, nothing else.

\defineframedtext[CenteredTextFrame][width=fit,location=middle]

\def\startCenteredText
   {\dosingleempty\dostartCenteredText}

\def\dostartCenteredText[#1]%
   {\bgroup
    \iffirstargument
      \def\docommand##1{\getparameters[][##1]}%
      \processcommalist[#1]\docommand
    \fi
    \startCenteredTextFrame}

\def\stopCenteredText
   {\stopCenteredTextFrame
    \egroup}

\starttext

\startCenteredText[myownparm="This is a test"]
   \startlines
	My own parm is: \myownparm
   \stoplines
\stopCenteredText

\stoptext

Yes, a much simpler solution, but I appreciate having both.
