is there also a way to determine the current output page number on which
typesetting is currently being made?  (I know this is a difficult problem in
LaTeX, and I presume the same is the case for ConTeXt, because it uses the
same underlying TeX engine.)

\realpageno
\userpageno
\subpageno

of course it depends on the pagebreak so the other ways is to use the 
referencing mechanism

Re: How to Determine the Current File Name and Line Number AND PAGE NUMBER in the ConTeXt Source?

[Mojca Miklavec]

Hello,

Did you take a look at the thread
     "How to Determine the Current File Name and Line Number in the
ConTeXt Source?"
from yesterday?

There's \jobname, but if you read from other files this won't help you.

I don't know of any way, but TeX sometimes complains on errors and
outputs the line number along. I could imagine an ugly hack: to
trigger an artificial error, read the line number, ignore that number
and continue ... but I don't know if that's doable. Another ugly hack
would be "talking to synctex". SyncTeX definitely knows the current
line number and file name, but I don't know if there's a way to fetch
those variables back to TeX. In any case it's probably something
that's equally difficult in ConTeXt than in plain TeX.

On the other hand, in LuaTeX there might exist elegant solutions.

What do you mean by "page number in ConTeXt source"?

See Hans' response.

... but LuaTeX simplifies matters a lot. In LuaTeX that should be doable.

There is \inputlineno in TeX, so  \the\inputlineno or the lua
equivalent \ctxlua{tex.inputlineno} will work.

Best wishes,

The problem is exactly locate the error in source .
Sometimes the errorline  of the log are in someway imprecise , ie. "the
errors is (are)
around here " .

Yeah, that can't be helped (unless you don't do multi-line paragraphs
nor macros)

we need something like a stack trace;
also a lua "try/except" construct should be nice .

Not now, you will need a bit of luatex interfacing that is not
programmed yet.
