flawed slices RegEx

[lyallp]

Please find the following two tiddlywikis (nice clean versions from tiddlywiki.com - version 2.2.4 )

 http://remotely-helpful.com/TiddlyWiki/TestSlicesDefault.html

This demonstrates various slice formats (around 700 or 800 combinations) and what the current 2.2.4 slice regexp does with the values.

This demonstrates a revised slice regexp (which currently does not support retrieval of more than one column of data) via a plugin. The *only* thing changed is the regexp. All the tests are identical. Not one failure. I would expect this regexp to be placed in the core.

I may have taken liberties with the expected slice naming convention, like allowing spaces in slice names.

Feel free to peruse the TheSlices? tiddler to see the various test cases.

The plugin in  http://remotely-helpful.com/TiddlyWiki/TestSlices.html contains the regexp I would expect to be placed in core.

I have created a plugin ImprovedSlicesPlugin?, located in contributors/LyallPearce/ImprovedSlicesPlugin or at  http://Remotely-Helpful.com/TiddlyWiki/ImprovedSlicesPlugin.html

The code in the plugin can be directly placed into the core.

(this superscedes the example regexp I supplied in the initial ticket text)

Also see  this discussion on tiddler slices' issues with table row headings and spaces in labels.

It has been  reported that slice names containing [brackets] are not recognized.

Unit testing also revealed the following flaws:

• table-heading markup (e.g. |!foo|bar|) results in the respective slice being ignored
• potential confusion between colon and table notation: "|''//~FooBar//'':|baz|" returns slice value |baz|

Priority increased due to failing unit tests.
