* Extend HTML tag parser to maintain an ordered array of attribute names
* Add some tests for repeated attributes
* Record entire attribute in orderedAttributes array so that we can work with duplicated attributes
@pmario and @welford - I’m not presenting this as a fix for #717
because I’m still not in a position to reproduce it.
However, I found this during a review of newline handling code, and
would be interested if it is implicated in the problems you are
reporting.
Fixes#82.
The old behaviour was to parse the content of a widget or html element
in block mode if the opening tag was followed by a line break. The new
behaviour requires two line breaks.
This makes it possible to include linebreaks more liberally within
wikitext, although care must still be taken to only use double line
breaks when the block mode behaviour is desired.
The code change here is very simple, just a single line change in
html.js. Most of the other changes are to convert various single line
breaks into double line breaks.
The purpose is to allow attributes to be specified as macro
invocations. For example `<div myattr=<<mymacro param1 param3>>>`. The
parser needed sprucing up in order to copy with the nesting of angle
brackets. The refactoring has been done with an eye on using the same
technique in the filter expression parser (which is pretty messy at the
moment -- it throws exceptions for syntax errors, which is bad). Later
I'm hoping to extend the technique to create a more flexible table
parser.
This arrangement takes better advantage of the similarities between the
now deleted widget renderer and the element renderer. It also obviates
the need for wrapper elements around every widget.
