The following code processes cleanly under TL2013 and fails with
ConTeXt ver: 2014.02.14 17:07 MKIV beta fmt: 2014.2.16 int:
english/english. I suspect a regression, but I am also open to being
told that I am doing things incorrectly.
I also notice that it fails (even under TL2013) if a space is inserted
after [#SETUP] in the doTrans intro. I thought that spaces should be
allowed in \starttexdefinition -- is this only in the body and not the
parameter description?
% macros=mkvi
\showframe
\let\EndTranslation\relax
\starttexdefinition Trans
\dosingleempty\doTrans
\stoptexdefinition
% The following should work, but fails with current beta
\starttexdefinition doTrans [#SETUP]#TRANSLATION\EndTranslation
\language[en]
\doifsomething{#1}{\getparameters[TR][setup=,#SETUP]\TRsetup}
\noindentation\blank[halfline]
(\,\ignorespaces#TRANSLATION\removeunwantedspaces\,)
\stoptexdefinition

Sorry for the not-so-minimal example with the obvious errors around the
setup. Here is a stripped version that shows the problem:
% macros=mkvi
\let\EndTranslation\relax
% The following should work, but fails with current beta
\starttexdefinition Trans #TRANSLATION\EndTranslation
#TRANSLATION
\stoptexdefinition
% This version works with both TexLive and current standalone beta
\def\Translation#TRANSLATION\EndTranslation%
{#TRANSLATION%
}
\starttext
Translation using \tex{def}{\tex{doTranslation}} works both with
TL2013 and current beta.
\Translation
It betrays a slow-witted mentality to pursue the streams, but not
to see the sources of things.
\EndTranslation
\blank
Translation using \tex{starttexdef doTrans} fails with current beta.

The \starttexdefinition was extended after the texlive release to support keywords like global or expanded and has therefore changed since then. The reason why it fails is that context passes the argument to Lua where they are parsed and at this point macros like your \EndTranslation are expanded. Even though this can be fixed I think it’s better to use the normal \def command when you want to create delimited commands.

No, spaces between arguments aren’t ignored but no spaces are added at the end of each line in the replacement text.
\starttexdefinition Test #1 #2
“#2” “#1”
\stoptexdefinition
\starttext
\Test ab cd
\stoptext
BTW: It’s better to follow contexts rules and use start/stop for environments, this way you can make use of the buffer mechanism to store text.
\unexpanded\def\startTranslation
{\begingroup
\dosingleempty\dostartTranslation}
\def\dostartTranslation[#1]%
{\iffirstargument
\getrawparameters[Translation][setups=,language=en,#1]%
\fi
\grabbufferdata[Translation][startTranslation][stopTranslation]}
\def\stopTranslation
{\language[\Translationlanguage]%
\Translationsetups
(\,\getbufferdata[Translation]\removeunwantedspaces\,)%
\endgroup}
\starttext
\startTranslation[language=nl]

Thank you for the excellent example. The only problem I see is that it
fails if no optional argument is present (in which case the keyval
settings \TranslationXXX never get defined). This is easily remedied by
removing the \iffirstargument and \fi wrapping the \getrawparameters.

Wolfgang (and list),
The above code works fine with simple texts, but is not movable. Adding
a footnote, as in the following, to the text section shows that:
\starttext
\startTranslation[language=en]
It betrays a slow-witted mentality to pursue the streams, but not to
see the sources of things.%
\footnote{%
\startTranslation[language=la]
Tardi ingeni est rivulos consectari, fontes rerum non videre.
\stopTranslation%
}
\stopTranslation
\stoptext
or even by:
\starttext
It betrays a slow-witted mentality to pursue the streams, but not to
see the sources of things.%
\footnote{%
\startTranslation[language=la]
Tardi ingeni est rivulos consectari, fontes rerum non videre.
\stopTranslation%
}
\stoptext
In LaTeX, this might be dealt with by a combination robust command
definitions and \protected. When I wrote an endnotes routine in LaTeX, I
used those and wrote the notes to a file which was then read back in at
the appropriate time, but that does not help with pagenotes.
I imagine that at the time the footnote is processed the
Translationsetups and Translationlanguage macros are no longer defined,
and I have no idea how one would reference the buffer contents, although
it does look like they have stable names in the log file.
Can this be made movable?
Also, am I correct that the \iffirstargument test in the definition of
dostarttranslation is redundant? My understanding is that \dosingleempty
assures the presence of [#1].
