Re: Translating from LaTeX to ConTeXt: environments

["Giuseppe Bilotta" <oblomov@freemail.it>]

So, I gave a look at the \definestartstop command, and tried it. It _is_
what I'm looking for, but I lack a full manual to understand exactly how to
fine tune it to my needs.

I trying to write a few commands that should work, e.g., as the color
command; I then need:

1) a "simple" version that works like

some text\Rev{text in a particular color to show revision}

some text\Rev[comment to go in margin]{text like in "normal" \type{\Rev}}

(I managed to do this, by lettin \Rev just scan for the following char and
choose depending on it being [ or not)

2) a "full" version that works like

\startRev
lots of paragraphs in revision color

lots of paragraphs in revision color

lots of paragraphs in revision color
\stopRev

\startRev[comment to go in margin]
lots of paragraphs in revision color

lots of paragraphs in revision color

lots of paragraphs in revision color
\stopRev

I can't seem to manage this. Anybody has any ideas? Follows the code I
managed to get to (but doesn't seem to work properly. why?):

\def\RevNote#1{\inmargin{\tfxx \color[blue]{#1}}}
\def\RevWithComment[#1]#2{\leavevmode%
    \RevNote{#1}%
    \color[red]{#2}%
}
\def\RevWithoutComment#1{\leavevmode%
    \color[red]{#1}%
}
\def\Rev{\doifnextcharelse{[}{\RevWithComment}{\RevWithoutComment}}

\def\RevisionsStart{\startcolor[red]\relax}
\def\RevisionsStop{\stopcolor}

\definestartstop[revisions][command=\RevNote,before=\RevisionsStart,after=\R
evisionsStop]

(the full name is revisions and not \Rev because the file is somewhat
converted from LaTeX and I needed different names)
