Re: [eLyXer-users] brackets with \left.

[Jens Nöckel]

Hi Alex,
yes - the \left. and \right. are now ignored. Just for fun I tried a different 
replacement by adding the following in "onefunctions":
u'\\left.':u'<span class="leftdot"></span>',
u'\\right.':u'<span class="rightdot"></span>'
That way, one would still have the invisible brackets marked by unused spans in 
the HTML output, and this could be used for later postprocessing. I'm not 
saying this needs to be in elyxer right now - I'm only experimenting to see 
what elyxer lets me do. Perhaps vertical scaling of brackets could be simulated 
by using the display:inline-block; style on a span that encloses the bracketed 
content (I see you already use that for fractions). I guess it will require 
Javascript to get the height of the enclosing box and scale brackets 
before/after that box to match that height. Well, that sounds like a lot of 
work, and in fact more like a case for MathML... but one can dream, right?

As for the tester honors, feel free to count me in. I'll keep using elyxer in 
various different situations in the future.

Cheers,
Jens
