Hi. Often, very simple papers will have the first page with a page
number at the bottom and all following pages will have a pagenumber at
the top. This is how I did it just now:
\setuppagenumbering [location=]
\setupheadertexts [\ifnum\pageno=1\else\pagenumber\fi]
\setupfootertexts [\ifnum\pageno=1 1\fi]
(Strangely, if I say, "\ifnum\pageno=1\pagenumber\fi", then nothing is
printed, yet when I use a literal "1" it works as expected.)
Is there a more idiomatic way that I'm missing?

Well, to mention a few:
% interface=en
%\setupfootertexts[\ifnum\pageno=1 \pagenumber\fi]
%\setupfootertexts[\doif{\folio}{1}{\pagenumber}]
\setupfootertexts[\ifnum\realpageno=1 \pagenumber\fi]
%\setupfootertexts[\doif{\realfolio}{1}{\pagenumber}]
\setupheader[state=high]
\starttext
\dorecurse{10}{\input tufte }
\stoptext
Now, the reason why \ifnum\pageno=1\pagenumber does not work has to do with
the fact that this expands to
\ifnum\pageno=11 since \pagenumber expands to 1. A space or \relax after
the 1 is the way out.
The real pagenumber is available as count register (\realpageno), or number
(\realfolio) while the pagebumber itself is available in ... you can guess.
With \doif, you need the string representation. [prefixing a number with
\number is a pretty good safeguard]

Thanks, Hans!

Well, I feel better now -- I was on the right track!

Yes, I need to look that up again in the manual, since I keep
forgetting what it does.

Why not distribute tufte.tex and knuth.tex in the context
distribution? :)

That's not what I'd expect:
\ifnum\pageno=1\pagenumber\fi
-----> [tokens] "\ifnum", "\pageno", "=", "1", "\pagenumber", "\fi"
... since I thought that tokenizing happens before any macro
processing. It's interesting.

They are in the cont-doc zip file [a few more too, like zapf]

actually tex reads a number until a \relax or space or something not
expanding into a digit is encountered. 2\pageno is also a number, i.e. 2
times \pageno. This is why you sometimes need a \relax. The following tex
code is potentially faulty:
\ifnum\somenum=\anothernum
\ifnum\anothernum>1
since tex will keep on reading and an \if is handled, so:
\ifnum\somenum=\ifnum\anothernum>10 3\else4\fi is pretty legal and is
equivalent to either
\ifnum\somenum=3 or \ifnum\somenum=4

I could not find a link to cont-doc.zip on www.pragma-ade.com, so I
edited the location of cont-tmf.zip, and that worked.

It's the same place. You can also access them from the beta page. The doc
files contain module documentation styles, say that you are at the context
path:
texexec --modu --pdf syst-gen
will give you a pretty printed source file of a system module [you may want
to take a look at the definition of \doifnumberelse to see a few \ifnum
tricks that make use of what we discussed in earlier mails),

That worked like a charm on the first try after I unzipped
cont-doc.zip into $TEXMF/tex/context and ran mktexlsr. Thanks!
