[AgileWiki] searching, more on simple ledger--negative numbers are a must!

[Bill la F. <laf...@ya...>]

Sougata,

I just realized you were asking about searching. 99%
of the time, we don't search. 

Mostly we resolve names within the current context.
You can see this now if you edit a document and
include in it the name of another topic which is
within scope and which is a ProperWikiName. (We'll get
into brace syntax later--it is not yet implemented.) 

You can see this partly at work with the topics
command. This lists the topics within name scope. 

Now remember I also mentioned inverted tables of
name/value pairs? These are for classifiers but are
not yet implemented. We've got a long way to go.

So we kinda do searching using recursive descent. And
we also use inverted indexes (but later). I asure you,
there is a lot of fun in store.

Unfortunately, we're not prototyping. so the priority
right now is to create a good wiki over an
architecture that supports all kinds of wild stuff,
and then expose the wild stuff later.

I do miss prototyping. Then playing with new ideas and
developing new techniques had priority. Of course, you
can't really put together a team of developers when
there is too much in flux. (I've tried with a team of
10 employees. Everyone gets very frustrated. Even when
later I tried with a team of 2 employees, by the time
everyone came up to speed, the design changed!) So the
advantage now is that when you have a question, I'll
likely know the answer. Its just a matter of getting
you up to speed as fast as we can. And the best way to
do that is to get a good grounding in how to use what
is already there. And that brings us back to my
favorite thing: code a little, learn a little. :-)

By the way, I'm very excited about simple ledger,
especially as we dropped the date field. It really is
a complete single-entry bookkeeping system. The jnl
command displays all the entries, and each row in the
table is a total for a given account. Indeed, if you
use negative numbers for debits, then the running
total should always come to zero.

(Please support negative numbers!!!)
