Unlike the HTMLArea version in ASciencePad, Bram's version seems to
handle most TW markup. I ran identical tests on ASciencePad
(abbreviated to ASP in the results below), Bram's HTMLArea (BCHTMLA)
and a copy of Bram's HTMLArea with the HTMLFormattingPlugin in place
(BCHTMLA+HTMLFP). Here's what I found when testing all the markup
listed at www.tiddlywiki.org's markup page. I used "Y" to indicate the
markup worked, "N" to indicate when it didn't work, and "?" when it
partly worked. I added comments where there was more detail to add:

Bold             ASP Y  BCHTMLA Y  BCHTMLA+HTMLFP Y

Italic           ASP N  BCHTMLA Y  BCHTMLA+HTMLFP Y

Underline        ASP N  BCHTMLA Y  BCHTMLA+HTMLFP Y

Strikethrough    ASP N  BCHTMLA Y  BCHTMLA+HTMLFP Y

Super script     ASP N  BCHTMLA Y  BCHTMLA+HTMLFP Y

Sub script       ASP N  BCHTMLA Y  BCHTMLA+HTMLFP Y

Highlighting     ASP N  BCHTMLA Y  BCHTMLA+HTMLFP Y

Preformatted     ASP N  BCHTMLA Y  BCHTMLA+HTMLFP Y

Headings         ASP Y  BCHTMLA Y  BCHTMLA+HTMLFP Y

Unordered list   ASP Y  BCHTMLA Y  BCHTMLA+HTMLFP Y

Ordered list     ASP Y  BCHTMLA Y  BCHTMLA+HTMLFP Y

Definition list  ASP N  BCHTMLA Y  BCHTMLA+HTMLFP Y

Block quotes     ASP ?  BCHTMLA Y  BCHTMLA+HTMLFP Y (ASP omitted the
block quote marker in the first row and adjusted the length of a
second marker dynamically depending on where the mouse pointer hovered
over the tiddler)

Block quotes 2   ASP ?  BCHTMLA ?  BCHTMLA+HTMLFP ? (I don't
understand what the "<<<" form of the blockquote markup is supposed to
do but all three TWs displayed the outcome as a single "<" on one
line, the text on the next and then a final line with a single "<".

Preformatted     ASP N  BCHTMLA ?  BCHTMLA+HTMLFP ? (The markup page
at www.tiddlywiki.org has two forms of preformatted markup. This is
the second of the two. ASP showed both sets of curly brackets while
both forms of HTMLArea show only the second set of triple curly
brackets)

Table            ASP N  BCHTMLA N  BCHTMLA+HTMLFP N (All showed rows
correctly but the rows were separated from each other. I didn't check
the COLSPAN and ROWSPAN options. An initial |CssClass|k row was
displayed as text rather than as formatting in ASP. I also tried all 3
versions with soft carriage returns at the end of each line of table
markup but that made no difference)

Macros           ASP Y  BCHTMLA Y  BCHTMLA+HTMLFP Y (All environments
recognised and ran an embedded tiddler (I used <<newTiddler>>). I
suspect that some macros which inspect tiddler content behave
differently in different environments. For example the macro
<<showtoc>> for DCTableOfContentsPlugin inspects headings. It
generated a macro error in BCHTMLA but generated some incomplete error
text that was not highlighted in the standard error colour in BCHTMLA
+HTMLFP. I did not know how to place it within ASP so I didn't try it
there).


I'm guessing therefore that HTMLFormattingPlugin may not be needed
alongside Bram's HTMLArea as available in AsciiMath-2.4.1.081008.zip
from 
http://sourceforge.net/project/showfiles.php?group_id=150646&package_id=169974&release_id=599120
unless it's somehow cleverer at running macros that refer to the
structure of the tiddler in which they're embedded.

The TW markup can be useful at present because there are some oddities
with the way this HTMLArea formats headings using its style dropdown
box. If I have to abandon this part of the HTMLArea toolbar I'm
wondering if I'll end up abandoning other parts once I've explored
them. And I'd be quite happy to use TW markup because my interest in
this version of HTMLArea is its ability to create mathematical
expressions and graphs, rather than its wysiwyg capability.

There's another potential advantage with tables. Although HTMLArea
provides a table insertion tool, I can't find a way to modify or
extend a table easily after it's been created. And you can't easily
paste the content of an old table into a new one of a different size.
TW markup though might make table extension easier.

In the light of all this I wondered:

1) have I missed any significant tests? I've been very focused on
markup but, apart from macros, I wasn't sure what else I should test
2) does anyone know of any other ways in which this version of
HTMLArea might impact other aspects of TW?
3) does anyone know if there's an online user guide to HTMLArea? (I
suspect it's considered so simple it doesn't need one, and the
original producers no longer support it, but such a guide might show
if tables really can be extended)

Thanks

Kevin
