And you think it's a good idea to use \expandafter in your document?
TeX version, not context ... :)
btw
\expandafer is not so bad, if used moderatly .
\expanded is the tool for users to get this result without knowledge
about TeX internals and expansion, this is from core-ntb:
% permits \expanded{\bTD ... \eTD}
\unexpanded\def\eTR{}
\unexpanded\def\eTD{}
\unexpanded\def\eTH{}
\unexpanded\def\eTN{}
yes, of course one need to know about \expandafter... so is not so
different .
But it's context style.
%%% luatex version
\startluacode
tprint = function(s) tex.sprint(tex.ctxcatcodes,s) end
tprint('\\bTABLE')
for j = 1,5 do
tprint('\\bTR')
tprint('\\bTD' .. j .. '.' .. '\\eTD' .. '\\bTD' .. j .. '\
\eTD')
tprint('\\eTR')
end
tprint('\\eTABLE')
\stopluacode
\stoptext
Nice solution and real alternative for package writers to avoid
\expandafter
and \expanded but nothing for a normal user, I should keep this
in my mind.
Are you sure ?
What is a normal user ?
As soon as you use \dorecurse , you become a programmer .
And sooner or later, everyone become a programmer, because it's
impossible to write a format that satisfied
all your needs .
