[tomboy-list] Question about Tomboy

[Alex Graveley]

Looking at the code again, we're still doing this synchronously on
every keypress.  It probably makes a lot of sense to do link
highlighting in an idle timeout, after a second or two of inactivity.
Should be pretty straightforward if some someone wants to try...

<for-the-adventurous>
You could an InterruptibleTimeout member in NoteLinkWatcher, and reset
it in OnDeleteRange and OnInsertText.  In the timeout's handler, do
the unhighlight/highlight currently being done after each keypress.

You need to keep track of the extents of the region the timeout
handler will scan.  This is just a matter of storing start_offset and
end_offset members in NoteLinkWatcher, and in OnDeleteRange and
OnInsertText setting start_offset = Math.Min (start_offset,
start.Offset) amd end_offset = Math.Max (end_offset, end.Offset).
</for-the-adventurous>
