\setupfloatcaption align=

\setupfloatcaption align=

[Alan Braslau]

Hello list,

According to the interface files
(texmf-context/tex/context/interface/mkiv)
\setupfloatcaption takes an align= parameter (inherits from
\setupalign). Additionally, it suggests that the location= parameter
can take the keywords tolerant, verytolerant and stretch.

None of this appears to work.

\setupcaption [figure] [align=verytolerant]
is ignored, and
\setupcaption [figure] [location={bottom,verytolerant}]
gives unexpected and surprising results.

I cheat, and use
\setupcaption [figure] [style={\setupalign[verytolerant]}]
but this is hardly a proper solution.

Question: Why do figure captions NOT inherit from \setupalign, i.e.
\setupalign[verytolerant] in a preamble does not have an effect on
float captions?

Question2: What is going on with \setupfloatcaption ?

Thanks

Alan

no mwe exposing your problem

some heuristics to determine the best width ... so that you still get a 
reasonable caption with very narrow figures and not excessive captions 
with too wide figures and when possible a one liner ... it's no problem 
adding some variants (there are some dimensions that can be set already) 
but the current mechanism is not going to change

Hans, I did not ask about funny behavior with captions in general, just
about the handling of key=value for align and with location=.

(And no MWE needed, as I am asking a question about the interface.)

sure but i want to see why something you expect to work doesn's

tolerance in text/par alignment is just that: adding tolerance and it is 
bound to align and it only kicks in in par building and there is not 
always a par involved

location has to do with the placement and float as a whole and there 
tolerance has to deal with snapping

so ... unrelated tolerances

Why does a float caption not build a paragraph? Does a \framed
sometimes not build a paragraph?

> tolerance has to deal with snapping

Not float location but \setupfloatcaption location (i.e. top,
bottom, ...): relative location of the float caption. 

> so ... unrelated tolerances

Please explain.

Thanks

it's not framed ... framed is advanced in the sense that it can analyze 
the build paragraph for the natural width

float captions look at the size oif the float plus some overshoot ... 
unrelated mechanisms

those are locations of the caption relative to the float

Maybe, a float caption *should* be a frame?
And if it isn't, I am asking why would a caption not be treated as a
paragraph?

That is what I have been trying to say!

So how does "tolerance" come into play?

it's not wise to change that now

because tex then tends to make it the width of the whole text so now (by 
default we measure and decide to go hbox or vbox
