\expandoneargafter?

\expandoneargafter?

[Hans van der Meer]

The ConTeXt system macro's used to contain a definition for \expandoneargafter (see Taco Hoekwater's article on this). What happened with it? It seems to have disappeared. A pity because I use it in my macros in several places.

! Undefined control sequence.
l.3 \expandoneargafter
                      \command{\abc}

Someone who can help?

Most of the command in context are now defined as \unexpanded
and because of this the command isn’t necessary anymore.

I see. But I used this for my own macros and now I cannot find the definition of \expandoneargafter.

\def\comparenumericprefix#1#2{%
  % remember that #1 (\firstsortelement) has to be expanded first!
 \comparenumeric{\expandoneargafter\uptodelim{#1}}{\uptodelim{#2}}}

Could it be that \expandoneargafter is defined as \expandafter\expandafter\expandafter?

syst-gen.mkii: \def\expandoneargafter   #1{\@EA#1\@EA}

but now you can write

\unexpanded\def\uptodelim#1{#1}

\def\comparenumericprefix#1#2%
  {\comparenumeric{\normalexpanded{\uptodelim{#1}}{...}}

and this will only expand “#1” but not \uptodelim.
