Hi all,
I made an n-up type layout tiddlywiki for printing out badge cards, mailing
labels, etc. using contacts stored in tiddlers. If the @page rule in CSS
worked, it would be absolutely "trivial" to do this type of layout. Just a
<div {width} {top-margin} {left-margin}>{{{filter||template}}}</div> while
your template can be a bunch of display:inline-block divs and things would
properly paginate.
However, I have found out that the @page rule that is intended to handle
print page margins in this scenario is wildly inconsistently implemented
among different browsers. Latest Firefox can be persuaded to cooperate put
Chrome wants to always apply manually defined margins. Which can be made to
work but you need to know what to manually set things to each time and that
changes template to template.
To get around this, I would like to have the user set the print margins
manually to "none" and handle the margins via div tags. However, I cannot
figure out if it is possible for tiddlywiki to iterate through a filter in
n-sized chunks until there are no filter items left. You can seemingly do
so up to some predefined finite limit just by calling
[tag[contact]first<n>] and then using a bunch of rest<m*n>limit<n> to keep
displaying m chunks of n templates grouped in a div with proper margins.
But you would need to know how many contacts to design for in planning your
proof sheet as there doesn't seem to be a way to use [tag[contact]count[]]
to loop through things count[]/n times.
Is there some way of using filter operators in this manner where you don't
need to know how many contacts in advance?
