Hi,
I uploaded a beta. Apart from some fixes, the biggest change is in
dealing with positional info and text backgrounds (first stage
cleanup). As I have no clue to what extend users mess around with
background graphics themselves, it's hard to predict side effects,
but the biggest impact is speed. The adventurous might want to try
out
Hi Hans,
there seems to be a typo in anch-pos.lua, line 100:
·································································
- local r = collected[region]
+ local r = collected[tag]
·································································
(“region” references a boolean.)
not so much a typo but i'll add some more checks
Here’s an example that triggers the bug and works after the
patch is applied. I have no idea as to why this exact series of
macros causes the issue. Please have a look at it anyways because
the text background looks weird even after.
·································································
\definetextbackground[tb]
\setuptyping[
after={\stoptextbackground},
before={\starttextbackground[tb]},
]
add [location=paragraph]
\starttext
foo
\starttyping
bar
\stoptyping
baz
\starttabulate[|r|l|]
\NC foo \NC bar \AR
\stoptabulate%
^^ missing \NC
\stoptext
·································································
Regards
Philipp
\setuptextbackground
[mp=mpos:par:region,
method=mpos:par:region]
or with some more visual tracing
\setuptextbackground
[mp=mpos:par:region:kind,
method=mpos:par:region]
A simple test with some 200 backgrounds brings down runtime with one
second on my machine (not the fastest anyway).
Apart from a performance gain, backgrounds are now also supported in
regular multicolumns as well as in some specific mechanisms like
tabulate and xtables. In xtables one needs to set region=yes in
order to get the desired results. Actually, the region key is a new
one in framed so anything that can be framed can also have fancy
text backgrounds.
Yet another improvement is that (although rather untested) you can
do things like
\starttextbackground[r] START
\dorecurse{10}{
\dorecurse{1}{\input ward }
\placefigure[right]{}{}
some text before BEGIN \dorecurse{2}{\input ward } END some after
\placefigure[left]{}{}
some text before BEGIN \dorecurse{2}{\input ward } END some after
\placefigure[right]{}{}
some text before BEGIN \dorecurse{2}{\input ward } END some after
}
STOP \stoptextbackground
\dorecurse{1}{\input ward }
and get more or less expected results. Keep in mind that it can
never get perfect due to all kind of possible interference. Also,
keep away from internals as they will quite certainly change.
