Re: [NTG-context] \dorecurse and \recurselevel in Natural Tables
Do I pick up any beginners book on Lua? There really is only one beginners book on Lua :-) _Programming in Lua_, by Roberto Ierusalimschy, the Lua author. There are a few other books, mostly about Lua and games, because Lua has become quite popular in the gamers' community, but Roberto's book is really excellent and makes a good tutorial. For example, one of the lines in the code is tprint = function(s) tex.sprint(tex.ctxcatcodes,s) end Is this Lua or LuaTex? The question does not really makes sense if you put it that way. This line of code is pure Lua, it is completely syntactically correct; but you can't use as it a standalone Lua script, because it uses functions that only LuaTeX and ConTeXt define (think of it as the action of import in Python, except that here it's not available as a stand-alone library call; it's built into LuaTeX). Hence, if you want to become proficient in Lua programming in ConTeXt, you need to learn: * The Lua programming language, with its core libraries (covered in the aforementioned book). * The Lua libraries that LuaTeX adds to Lua, documented in the LuaTeX manual. * The Lua libraries that ConTeXt adds to LuaTeX. The above line of code is really a mixture of the three, but in any case, the ground stone is always Lua.

Nice article but I have a few corrections for you.
Table setup:
To achieve horizontal and vertical centered content in the table cell
you need 'align={middle,lohi}'.
Pure table code:
You forgot the \bTR and \eTR before and after each row.

The first recurselevel was expanded with your \edef and the second

OK, it's hard to write a fancy layout without defining your own header styles etc. without a definition but use then as many high level contructs (\framed, \define, ...) as possible and try to avoid things like \vbox or \expandafter. This is my point of view : use TeX to write a document = write a program in TeX programming language TeX programming language is not like lua, python, c++ , java and so on; TeX programming language is like m4, ie a macro language. If you write a simple document (= a simple program) context high-level const.s will almost completly hide the programming aspect ; but it's impossible that context high-level cover *all* program; so sooner or later one will use lua(tex) expression (which can be a natural choice for most of programmer but can be slow) , or ContTeXt macro (which can be less slow but not so natural ) , or even TeX macro - primitive . http://texblog.net/latex-archive/plaintex/expandafter/ hey, this is not a moderate use of expandafter as I intended .. I dropped latex for similar examples .

I don't like the

construct
because sometimes the \def\macro{\oldmacro...}
can cause unexpected behaviour

This is non trivial example, normally I would define a new quote
command with
\definedelimitedtext[quotesmall][quote]
but you above code can't be achieved with this because the results are
either
small text or text with quotes at both sides but not a combination of
them.
How about: \define\quotesmall{\groupedcommand{\quote\small}{}}

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.

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 .

As your other solutions, this worked great. I suppose I have to use \expanded
for every \bTD \eTD pair. Can you please explain why this is necessary or point
me to a document that contains the explanation.

Follow the mailing list and read parts of the source.
Is this Tex programming or Context programming.
It's a ConTeXt future.
You can use inside of \dorecurse #1 to get the expanded level
and #2 to get the recurse depth.
