Ack. Scrub that, that box has a ropey pthread install.
Sorry for the noise, I'll try an --enable-pthread install of ruby again...

I'm not sure what the problem is... What sort of circumstance will this 
cause a problem? Perhaps you are thinking that assignment should do 
something more than it was intended to.

Using your Pointer example, you could do this:

   p = Pointer.new()
   x = p[] = "hello"
   (p[] = "hello").inspect

In line 2, would you expect something other than a simple "hello" 
string to be assigned to x?
In line 3, would you expect #inspect to be called on p, rather than on

I understood that. previously I had thought that the focus of the

Right. the RubyGarden Wiki is a great information repository, but it's 
got it's own purpose, and I'm afraid it wouldn't be dynamic enough for 
what would be necessary to make things work. There would need to be at 
least some sort of message board system included, and a mailing list.

I really like the idea of starting it out as a sort of "meta-project" 
on RubyForge. I think that should be the way to go.

The installer that I'm thinking of would install Ruby itself, and extra 
libraries, not just extensions. I think that a sort of meta-gem that 
only has dependencies could easily be a part of it, though... after 
installing ruby, rubygems, some gui toolkits, etc, it could run a gem 
that installs some important development items like RedCloth, etc...

I didn't get the idea that rubygems would ever be something that you 
would use to install anything other than ruby libraries, but maybe I 
was mistaken?

Re: [ANN] Tycho - A PIM under development

I like the user interface, looks like it would be really nice to use.

Features I would like to see:

I would like to add fuzzy searches tothe list as I and I'm sure others
can't spell.  Also search for words near each other and search by word
list - as you start typing a word the words in the index that have those
letters appear in a list -  for example if you type a, all the indexed
words starting with a are in the list.  As you add letters the list
becomes smaller leading to the word you are looking for similar to the
index search
option in Windows.

Search results ranked by different options - most hits, hits in certain
fields, most matching words, newest documents, oldest documents and
probably others I haven't thought of.

Import feature that knows different formats.  For example I would like
to index my email - it should know that there are To:, From:, Subject:
lines etc in the mail and store the messages so they can be searched
by the automatically created indexes from the email template.  Same
with pdf files, word docs etc.  Also for the import option a date
qualifier
so for example you can do a import since a date for example when adding
your email to the database - you would like to add only new messages.
The same for indexing a web page or a set of notes.  Or use the stored
time to see if the document has been updated since the last import.  
If you have edited the database version and it has changed from where
you are importing from you might need to resolve how you are going to
handle the dual update - replace, add 2nd copy, merge or something like

   This is a fairly core restriction: while SciTE can have multiple files
loaded at once and can display tabs to switch between them, there is no way
to see the contents of more than one file at at time. I am unlikely to agree
to lifting this restriction as I want SciTE to remain simple. For more
complex tasks, a more featureful application would be a better fit. If
others wish to start a project that adds multiple views to an extended
version of SciTE then I'll try to help out so that they can continue to
benefit from enhancements to my version of SciTE.

   For Ruby development, I feel you are much better off with an application
designed around the needs of Ruby including integration of debugging, use of
Ruby-compatible regular expressions, and an understanding of the files that
make up a Ruby project and the links between them. It would be a good idea
to develop such an application in a sensible high level language like Python
;-) rather than C++. FreeRIDE seems to be on the right track.

Good effort, Trevor.  This definitely seems a step in the right

This was what I wanted to express, though I could not write it in such a striking
sentence  :-)

I don't know what is right nor wrong...

Maybe make __FILE__ a class with a one useful method, #standalone?
So that instead of 'if $0 == __FILE__' you can type 'if __FILE__.standalone?'

Maybe make a System class, containing a $0 replacement?

What does other languages do ?
