- This is implemented as a post-processing pass.
- Might require additional checks to verify rewriteability.
- Implemented as a pair-wise tag DOM minimization strategy,
i.e. it takes tag pairs (B, I) for ex, and attempts to
normalize the tree just for those tag pairs. Normalizing
across multiple tags is implemented as pairwise rewriting
across all pairs: Ex:(b,i), (b,u),(i,u) for (b,i,u)
- Copied over attributes as part of rewriting, but some of the
attributes lose their meaning on rewriting since tags are
reordered (ex: sourcePosn, sourceTagPosn). How do we handle this?
Output examples and possible issues to fix:
<i><b><u>biu</u></b></i><b><u>bu</u></b><u>u</u>
gets rewritten to:
<u><b><i>biu</i>bu</b>u</u>
But, the equivalent wikitext form:
'''''<u>biu</u>''''''''<u>bu</u>'''<u>u</u>
does not get rewritten because of parsing differences.
This wikitext gets parsed into:
<i><b><u>biu</u>'''</b></i><u>bu<b>u</b></u>
The extra ''' token in the middle thwarts DOM rewriting.
However, a slightly different version:
"'''''<u>biu</u>''<u>bu</u>'''<u>u</u>"
gets properly normalized to:
<u>'''''biu''bu'''u</u>
An alternative, but fun strategy to play with is to use the following
two normalization primitives: S(wap) and M(erge).
- S rewrites T1(T2(x)) into T2(T1(x))
(ex: <b><i>foo</i></b> ==> <i><b>foo</b></i>)
- M rewrites (T(x),T(y)) into (T(x,y)).
(ex: <b>foo</b><b>bar</b> ==> <b>foobar</b>)
The current rewriting strategy could possibly be re-implemented as S-M
rewriting. The problem to solve there would be to find an efficient
rewriting strategy that is guaranteed to lead to a normal form. I may
not play with it now, but just documenting it for later (to play with
in my spare time).
This commit is just as a record of fun/experimental code where I get to
learn details of JS, wikitext, parsing, and DOM manipulation. Next
version of this code will attempt to introduce minimal DOM restructuring
across multiple tags at once which can be more efficient.

This was caused by the fact that a non-structural leaf can not have children, which makes it appear incompatible as a sibling to an arbitrary structural element (like a paragraph) but since it can not contain content we can check that instead.

Using this argument will only return true if the offset is a place you can add any element to (hence the unrestricted part of it). This is good for testing if a paragraph could potentially be inserted there.

The 'insert' and 'remove' operations weren't implemented in the

Also migrated the tests, especially those that asserted that consecutive

roundtripping).
- There is no output normalization yet which is needed for now since we

* All parser pipelines including tokenizer and DOM stuff are now constructed
from a 'recipe' data structure in a ParserPipelineFactory.
* All sub-pipelines of these can now be cached
* Event registrations to a pipeline are directly forwarded to the last
pipeline member to save relatively expensive event forwarding.
* Some APIs for on-demand expansion / format conversion of parameters from
parser functions are added:
param.to('tokens/expanded', cb)
param.to('text/wiki', cb) (this does not work yet)
All parameters are additionally wrapped into a Param object that provides
method for positional parameter naming (.named() or conversion to a dict
(.dict()).
* The async token transform manager is now separated from a frame object, with
the frame holding arguments, an on-demand expansion method and loop checks.
* Only keys of template parameters are now expanded. Parser functions or
template arguments trigger an expansion on-demand. This (unsurprisingly)
makes a big performance difference with typical switch-heavy template
systems.
* Return values from async transforms are no longer used in favor of plain
callbacks. This saves the complication of having to maintain two code paths.
A trick in transformTokens still avoids the construction of unneeded
TokenAccumulators.
* The results of template expansions are no longer buffered.
* 301 parser tests are passing
Known issues:
* Cosmetic cleanup remains to do
* Some parser functions do not support async expansions yet, and need to be
modified.

* Fixed the order of execution of parent class constructors in ve.dm.LeafNode and ve.dm.TwigNode so that canHaveChildren and canHaveGrandchildren produce correct values and added tests to ensure these methods are correctly inherited in subclasses
* Added tests that check for exceptions when adding nodes that can have children to nodes that can not have grandchildren
* Added test that check for events being emitted before and after splicing, including that beforeSplice should be emitted even in cases where a splice fails and throws an exception because the nodes are incompatible (but afterSplice is not called in this case) since beforeSplice might modify the nodes in some way before the compatibility tests are run
