I'm using ASCIIMathML andASCIIsvgwith HTMLArea in TiddlyWiki. The
implementation I have
fromhttp://sourceforge.net/project/showfiles.php?group_id=150646package_...
invokes a window (called the Equation Grapher Control Panel) in which
I can specifiy graph parameters to create SVG graphs. But theASCIIsvg
home page suggests I might also be able to form my own drawings by
embedding some material in web pages.
By pasting examples similar those on theASCIIsvghome page into the
raw html viewer of HTMLArea available via a toolbar button I've got
my
browser to recognise that an svg object is to be rendered (the right
mouse menu is appropriate to SVG) but myASCIIsvgcode isn't
generating a drawing.
My latest simple example is the following which amounts to an entire
Tiddlywiki tiddler:
pStart text/pembed src=HTMLArea\Plugins\AsciiSvg\d.svg
script=initPicture(-2,2,-2,2);axes();line([-2,-2],[2,2]); /p /
pEnd text/p
(The instructions on theASCIIsvghome page say that the script
delimiters should be single quotes but the HTMLArea editor converts
them to double quotes even when I manually change them back).
When I display the resultant page I get an empty SVG area surrounded
by my start and end text and sometimes get a dialog box saying only
undefined though it doesn't make clear what is undefined.
When I compare the html here with the html generated by the Equation
Grapher Control Panel wiindow the latter uses an sscr attribute to
specific the graph I think but I can't find out what the sscr element
is. And in any case it doesn't seem to be part of theASCIIsvg
vocabulary as far as I can tell.
I tried the same material in an ASciencePad tiddler but had no
further
success there.
So does anyone here know if I should be able to specify my own
drawings in the TiddlyWiki/HTMLAea environment and if so how I'd
speciify them so that they draw completely please?
David:
The sscr attribute is a short script that is the abbreviated format
used by the Equation Grapher Control Panel.
When I wrote theASCIIsvgplugin for HTMLArea, there were two files
in
addition toASCIIsvg.js: AsvgHA.js (or ASCIIsvgHA.js) and
ASCIIsvgAddon.js. The former is used in the editor window itself;
the
latter is intended to be included in the output.
Looking at it, it appears that I stripped the script attribute
handling out of AsvgHA.js (in the drawPics function). Not sure
exactly why. The handling is still in ASCIIsvgAddon.js, so it should
be possible to add it in to AsvgHA.js.

Here's what I found when I tried this.
I placed the following in a wyswiwyg tiddler within Bram Chen's

embed src=HTMLArea/plugins/AsciiSvg/d.svg script=border = 0
initPicture(-10,10)

p[p.length] = [t*cos(PI*t), t*sin(PI*t)]
path(p) /
It's code from an example of a drawing at the ASCIISVG home page at
http://www1.chapman.edu/~jipsen/svg/asciisvg.html but modified as
follows:
1) When I save the original raw embed statement, the delimeiters for
the script are changed from single quotes to double quotes and this
throws errors when the script encounters the red attribute. So I
changed the script delimiters to double quotes and the delimiters
within the script itself to single quotes
2) The original example begins embed width=117 height=117
src=d.svg ... The HTMLArea editor strips out the width and height
elements - I don't know why. But I think they're being remembered
because the SVG output seems to be affected by them nonetheless as
mentioned below
3) The original example refers to d.svg in the wrong location for
Bram's HTMLArea and I corrected it.
The result was that I did indeed see the drawing when I switched out
of raw html mode and back to normal viewing within the editor.
Another oddity was that I'd initially used a version of the embed
statement that omitted the height and width statements and the drawing
had been truncated on the right. When I replaced the width and height
statements, the drawing appeared correctly even though html view in
the editor no longer showed the width and height statements.
However, the drawing only appears as an empty SVG area when I view the
tiddler oustide the editor. Hence I'm only halfway to the desired
solution.
If I place the same embed statement in a non-wysiwyg tiddler (so it's
never been touched by HTMLArea) I just see the embed statement when I
view the tiddler.
Overall I'm therefore left wondering:
1) How can I get the drawing displayed when viewing the tiddler? Is
there perhaps an equivalent place in my TW where I need to get the
right code to execute at view time instead of edit time?
2) Can I stop HTMLArea swapping the script delimeters to single
quotes?
3) can I stop HTMLArea removing thew width and height statements?
4) How would I invoke the same drawing from a non-wysiwyg tiddler.
(Maybe the answer to 1 above will help here).
I'll let you know if I learn more but if anyone has any insights that
might help further, please by all means let me know.

In a standard (non-wysiwyg tiddler) I get the same output as for a
wysiwyg tiddler when the tiddler is displayed - an empty SVCG pane -
if I surround the embed statement with html and /html which is
needed, I believe, to tell a standard tiddler to behave as a chunk of
html.
In both cases therefore the formost challenge seem to lie in getting
the drawing to draw on the SVG pane. As the drawing is defined by the

when a tiddler is displayed as against when it's edited in the

I also get truncation on the right of the drawing when I first view it

[tw] Re: Using ASCIIsvg in TW
Just on the truncation of the spiral drawing ...
The top and bottom truncation is fixed if I specifiy the y-axis
minimum and maximum explicitly in initpicture(-10,10,-10,10) rather
than initpicture(-10,10). I don't know why the version of ASCIISVG
that I'm using needs this when the ASCIISVG home page does not.
I still don't understand the right-hand truncation. The drawing
initially appears in HTMLArea as a square with the origin offset to
the right because the x axis runs from -10 to only approximately 3.
The region with x from 3 to 10 is all missing. When I view the tiddler
in html mode and then revert to wysiwyg mode, the full x axis is shown
but on a drawing which is now wider than it is tall, the x-axis
spacing remaining the same as it was originally shown but the drawing
is wider to accomodate the x region from 3 to 10.
Yet, when the tiddler is viewed after editing, the drawing is square
and correctly formed again.
Ultimately I need the drawing correct in view mode and that's working.
But it'd be great to fix the editing mode which is, after all, meant
to be WYSIWYG.

[tw] Re: Using ASCIIsvg in TW
Interesting. I tried the embed etc material in Firefox too but still only saw the script. That's almost a relief anyway because my Firefox objectes to pasting into a tiddler because of security problem that I haven't been able to fix yet, but pasting example SVG code is much faster and less error prone than retyping it by hand. I tried placing d.svg adjacent to the TW and even an extra copy of the original ASCIIsvg.js there although the header markup wouldn't have known about the latter and neither made any difference. It's such a shame because the drawing facilities are so useful as well as the graphing facilities. And, presuming that the graphing facilities invoke the drawing facilities anyway, I feel drawing by providing the ASCIIsvg code must somehow be possible. For now I'm using a separate web page to draw my images and am using SnagIt to take a screenshot of the drawing which I then place in the tiddler as an image. This admittedly has the advantage that it can be viewed by anyone with IE but without the SVGViewer but my pages typically include mathematical notation via ASCIIMathML so they need the MathPlayer anyway. AQnd I couldn't reasonably expect any other user of my TW's to do this. And I can't render dynamic images using screenshots as I could theoretically with ASCIIsvg. So I'll keep thinking about this to see if I can find some way to get ASCIIsvg code invoked. And I didn't realise there's a plugin to store images in TWs - I'm holding mine in an Images folder alongside but this reduces portability I feel. So I'll explore that too - thanks for the tip.

However there is still a concept that I would like to try and that I used long time ago when I was still working on my CP/m system. At that time I constructed graphs directly in video memory, this worked fine. Something similar could be done by dynamically altering an image that is stored in a tiddler. There is a plugin for storing images in tiddlers available. At least this would solve IE problems I think. Maybe there are some programmers out there how would like to pick up this concept.

I'd forgotten about this source but found a similar one called CTY's Math TiddlyWiki athttp://www.jostylr.com/deli.html last night, so thanks for the reminder. They both use ASCIIsvg stand alone from the enhanced HTMLArea of Peter Jipsen and Bram Chen which I'm hoping to use and I'm guessing that I might confuse my TW if it includes two versions of ASCIIsvg for now. Paolo's examples solely use script to generate graphs or other drawings which is exactly my aim, but in addition to the graphing front end that Bram mentions above and which works in my TWs. They just seem to embed the code in a standard tiddler surrounded by html tags and it'd be great if I could do that in HTMLArea but my experiemnts have all failed and I just see the code. CTY's surrounded the code with two backticks but that might also complicate my copy of HTMLArea which uses a single backtick to surround ASCIIMathML markup (as does Paolo's I think). Lastly, both copies throw object errors when I try to display the sample graphs and drawings in IE6 but then Paolo warns it's not tested for IE. A quick trial at the link you posted worked fine in Firefox. I haven't stteled on my likely browser yet though I'd prefer IE because that's the native browser on my target PCs. Both throw inconvenient security messages that I've still not got rid of entirely and Firefox objects to pasting html without a complicated-looking change to the browser environment which I'd have to do on each PC - not very appealing. So there's a lot left to settle but if I could just invoke ASCIIsvg via code in addition to the graphing front end, all in HTMLArea in at least one browser, that'd be a great step forward. And if I can't, I may fall back to your option with FireFox. So thanks for the clues. Kevin On Oct 17, 5:01 pm, okido [EMAIL PROTECTED] wrote: Hi Kilucas, I made some graphs with little effort.

Bram Thanks for this and this parameter screen generates fine when I use the trigger button on the HTMLArea toolbar. But I think it is only useful for graphs.

Do you think this is possible perhaps?
