Well done John. It looks like you are making amazing progress with the parser,
which I would say was the single most important feature to ease the future
development of FlexWiki. With a good parser in place it should be easier to add
new functionality and push FlexWiki to the forefront of wiki products again.
Thanks,
Derek.

Subject: [Flexwiki-users] New Features in New Parser
Progress on the new parser can be followed at [1]. The rule sets are nearing
completion with the current implementation of tables done and most links now
being managed in addition to handling of emoticons, lists, headers, etc.
One of the frustrations from the original parser was that some links that ended
with a period worked, while others did not. This condition was documented, but
still caused problems. The new parser will now allow punctuation at the end of
a link and ignore it.
More importantly the new parser will make it possible to add new features
easily, where this would have been extremely difficult in the original parser.
Feedback and discussion on any of these proposals is welcomed.
First is the addition of the 'valign' style property to table rows or table
cells. The choices will be 'VT' - top, 'VM' - middle, 'VB' - bottom or 'VBL' -
baseline. The token must be enclosed in the style sequence '{.....}'. If the
token is in the first cell in the row it will be applied to the html <tr>
element. If it is in any other cell in a row it will be applied to the
corresponding cell html <td> element.
Similar treatments can be added for table padding and spacing to override the
default values in CSS for the entire table. These would again be applied at the
corresponding row or cell. The token would be 'Pdd' or 'Sdd' where 'dd' are
digit values of pixels.
Definition lists - html element <dl> with sub-elements <dt> and <dd> - will be
added with the indentation level controlled by each tab or 8 spaces equalling
one level of indent up to 7 levels. The actual for of the input will start with
a semicolon, then the term being defined, followed by a colon and then the
actual definition of the term (see below):
;term:definition
Acronym - html element <acronym> - will be added by having the acronym directly
followed by an opening bracket, then the full text representation of the
acronym followed by the closing bracket. This can occur anywhere in text. This
element is useful for style sheets and search engines. An example follows:
ABC(American Bridge Club)
Finally the big one. Tables with multiple lines in any cell, where those lines
can include any wiki text except another embedded table. For example, this will
allow the easy placement of lists within a table cell. In order to achieve this
it is necessary to define a new token to identify table row start and end.
These will be '[||' and '||]' respectively, where the row start is found at the
start of a line of wiki text and the row end is at the end of a line of wiki
text, with any number of lines of wiki text intervening between the two tokens.
The new cell token will remain as '||'. The existing single-line table row
definitions will still be supported and current topics that use wikitalk to
simulate multiline table will continue to function correctly. An example of the
new format is shown below (note that the position of the cell break token '||'
is unimportant):
[||{T^} * first item of unordered list
* second unordered list item
* third unordered list item (all in first cell of first row ||
The second cell of the first row ||]
[|| first cell of second row
|| second cell of second row
contain LF/CR in text ||]
I have not yet really looked at including any microformat definitions, but
certainly these could be included if I receive input about which ones should be
supported. It should also be noted that the implementation of these rule sets
will allow local wiki administrators to update and include their own rule
definitions, as the rule sets are in xml configuration files that are read by
the application.
