\defineenumeration

Syntax

\defineenumeration[...,...,...][...][...,...=...,...]
[...,...,...] name
[...] name
[...,...=...,...] see \setupenumerations


Description

With \defineenumeration you can define the commands for a numbered text element, like remarks or questions. For example, if you want numbered remarks in your document you can define the environment as follows:

\defineenumeration
[remark]
[location=top,      % use alternative=top in MKIV
text=Remark,        % Display header as "Remark 1"
headstyle=bold,     % Bold remark headers
inbetween={\blank[nowhite]},   % No blank line between remark header and remark
after=\blank]       % Blank line after the remark.

This creates the new commands \remark, \resetremark, \nextremark, and \startremark ... \stopremark, as well as the same commands for subremark and subsubremark.

Examples


\setupindenting[yes,small,first]

\defineenumeration
  [remark]
  [location=top,text=Remark,inbetween={\blank[nowhite]},after=\blank,headstyle=bold,margin=1in]

\starttext
  \remark
    An enumeration (\tex{remark}, in this case) takes the paragraph that follows 
    it as its argument.

  \remark
    This is the first paragraph after \tex{remark}. It is part of the remark.

    This is the second paragraph after \tex{remark}. It is not part of the remark.

  \startremark
    This is the first paragraph inside \tex{startremark}. It is part of the remark.

    This is the second paragraph inside \tex{startremark}. It is part of the remark.   
  \stopremark

  \subsubremark Presto!

\stoptext

Gives:

The heading can be placed on the same line as the text that follows by using the value 'left' for the location property (or alternative in MKIV). The width of the header is controlled by the 'width' parameter, and the spacing to the text by the 'distance' parameter. The text on the left side of the number is defined by 'left' and the text on the right by the 'right' parameter. Below the chapter number is appended before the enumeration number. The text before the number can be overridden with the 'text' parameter. Before we override the default text 'remark' with no value.

\starttext

\chapter[chpt1]{Chapter 1}

\defineenumeration[remark]
    [location=left,left={\in[chpt1]}.,right=:,width=0.3in,distance=0.02in,text=]

  \remark
    An enumeration (\tex{remark}, in this case) takes the paragraph that follows 
    it as its argument.

  \remark
    This is the first paragraph after \tex{remark}. It is part of the remark.

    This is the second paragraph after \tex{remark}. It is not part of the remark.

  \startremark
    This is the first paragraph inside \tex{startremark}. It is part of the remark.

    This is the second paragraph inside \tex{startremark}. It is part of the remark.   
  \stopremark

\stoptext

Gives:

Having the chapter number automatically prefixed can also be achieved using the "prefix" key (instead of putting in the text with the "left" key):

\setuphead[chapter][page=no]  % to fit example on one page
\defineenumeration[problem][way=bychapter, prefix=chapter, text=Problem]

\starttext

\chapter{Chapter One}

\startproblem
Easy problem.
\stopproblem

\startproblem
Hard problem.
\stopproblem

\chapter{Chapter Two}

\startproblem
Easy problem in chapter 2.
\stopproblem

\stoptext
