To 'substitute and wikify' some content, you don't need to create a
plugin or custom macro... instead, try this:
First, define a tiddler, [[ScaledImage]], containing:
<html><img src="$1" style="width:$2;height:$3"></html>
then, to use it, write:
<<tiddler ScaledImage with: foo.jpg 150px 150px>>
The parameters following "with:" are automatically inserted in place
of $1, $2, $3, etc... (up to $9) when the content from [[ScaledImage]]
is rendered.
You could even generalize this a bit further by writing
[[StyledImage]]:
<html><img src="$1" style="$2"></html>
which could be used to produce the same results as above by writing:
<<tiddler StyledImage with: foo.jpg "width:150px;height:150px">>
but could also be used to apply other CSS styles to that image, like
this:
<<tiddler StyledImage with: foo.jpg "margin:1em;border:10px outset"
enjoy,
