I agree that would be useful in certain situations. Making it even
more useful would be if it could show you the upward tree of any
language structure, not just brackets. So for instance, if I have
this HTML in my window:
...
<table>
<thead>
<tr>
<insertion point>
</tr>
</table>
...
the status display would show something like:
html > body > table > /thead/ > tr
to show me both what the structure is at the current point in the
document, and whether that structure is properly balanced (in this
case, the thead isn't balanced, so it's marked). Language-specific
settings could be used to, for example, hide the html and body contexts.
This would be especially useful when I have to work on HTML documents
that someone else generated with GoLive or something.
Implementing this would require adding some basic (as in low-level,
not easy!) intelligence to the parser that it doesn't already have.
For example, the Balance command will balance the bracket pairs in
this PHP code:
if ($foo) {
$bar();
} else {
baz();
}
but it doesn't understand the non-brackets-based if structure in this
equivalent:
if ($foo):
bar();
else:
baz();
endif;
which I prefer because of its increased readability. I've also
noticed that the Close Current Tag command for HTML is almost always
broken once a page starts incorporating some PHP; I'm not sure how or
if that relates to the Balance command internally, but it could be
indicative of yet more work needing to be done under the hood to
bring this suggestion to life. (Of course, I wouldn't mind these
shortcomings getting addressed in any case....)
Any thoughts on my revised version?
Regards,
Bob
