\setupheadertexts \setupfootertexts

\setupheadertexts \setupfootertexts

[Alan Braslau]

Hello,

\setupheadertexts [{center}]
sets a centered header (and wipes-out any left and right header)

\setupheadertexts [{left}] [{right}]
sets the left and right headers (and keeps the centered header)

\setupheadertexts [{left odd}] [{right odd}] [{left even}] [{right even}]
sets the left and right headers for even and odd pages
(perhaps I have this backwards?)



(1) It would be useful to have
	\setupheadertexts [{left}] [{center}] [{right}]
but this does not work.
In this case, we probably also need a *six* argument version (even/odd).

(2) It would also be useful that
	\setupheadertexts [{center}]
NOT wipe-out left and right if they are set
(but I could live with this perhaps historical behavior if we were to have (1).)

(3) It is a bit messy that one must use
	\setupheader []
	\setupheader [left] [right]
*two calls* in order to have no centered header.
(Again, I could live with
	\setupheader [left] [] [right]
if we were to have (1).)


Similarly for footertexts, of course.
What is the reasoning, presently?



ALTERNATIVELY (or additionally), we could have

\setupheadertexts [center={center},
                   left={left},
                   lefteven={left, even},
                   ...]

which would be even cleaner.

Thanks,

Alan

When you use three arguments the first is used for the position of text, 
i.e. above the text, margin or edge areas.

Only six or seven arguments work in this case but this only useful in a 
double sided document.

You need a new command for this because adding an assignment option can 
produce unexpected results, e.g. the example below won't work anymore.

\setupheadertexts[{\date[d=...,m=...,y=...]}]

I know this, and I find the syntax unfortunate, to say the least.

Indeed, a double-sided (asymmetric) document.
And it is pretty unwieldy.

Well, what would make sense?
I would have no problem dropping/ignoring this (historic) command.
How about:

\setupheader [left=,leftodd=,middle=,...]
\setupfooter

or

\setupheader [lefttext=,leftoddtext=,middletext=,...]

This would be logical.

we have a lot or areas ... and if you really want you can do this ...

\setuplayouttext
   [header][text]
   [lefttext=L,
    middletext=M,
    righttext=\doifoddpageelse{RO}{RE}]

\setuplayouttext
   [footer][text]
   [lefttext=L,

    righttext=\doifoddpageelse{RO}{RE}]

\setuppagenumbering
   [alternative=doublesided]

\starttext
    test \page test \page test
\stoptext

Has been there for ages ... (but I never use that method).

I has the same question a few years ago but I never used it
because it has a few limitations like missing style/color support.

\setuplayouttext[header][text][lefttext=L,middletext=M,righttext=R]

%\setupheadertexts[M]
%\setupheadertexts[L][R]

\setupheader
   [color=red,style=bold]

\setuppagenumbering
   [alternative=doublesided]

\starttext
\dorecurse{2}{\page[dummy]}
\stoptext

I am looking for a simple and obvious way of setting header and footer
texts. The \setupheadertexts has limitations and I view this as
historical, for ConTeXt commands have evolved over time usually towards
better solutions, even if we leave in place for reasons of backward
compatibility habits that can be hard to quit.

One example is \setuppapersize [page=letter,paper=letter]
(sorry, and I *do* much prefer A4).
This is, I believe, far superior to \setuppapersize [letter] [letter]


Do you find that keys in \setupheader make sense? If so, what choice?
(as we like to limit the proliferation of key names).

Alan

What limitations? \foo[{sometext}] is not that different from 
\foo[text={sometext}] and often I do

\setupheadertexts[\setups[header}]

\startsetups
   lots of stuff
\stopsetups

because you don't want to add all kind of stuff in a value.

A matter of taste but we're not going to drop something ... that kind of 
compatibility has always been a principle. If one has few docs it's no 
problem to adapt a few styles but it's a no go otherwise (and I'm not 
even speaking of adapting all kind of manuals, examples, etc etc.)

And for most of those commands there are k/v varianst too.

(\setuppapersize actually takes lists as page setups can be more complex 
than just 'letter')

(But I'm willing to remove the command that I know you hate most, namely 
{ {foo} \over {bar} }.)

\setupheader is used for styling and such, not for content.

actually there is not really a \setupheader as these are shortcuts to a 
few kind of generic commands that set up properties of these areas (a 
matrix) on the one hand, and set the content with a different command

(also, this part of context is quite optimized deep down because 
checking 25 areas for all possible properties each page flush is costly, 
so it would be a major rewrite with little gain; it would also mean 
dropping \setuphead etc and using one command for everything ... not 
something i want to do in the middle of other transitions like 
mkiv->mkxl and such)

I can look into that but only when there is no speed penalty
