rfind-1.0: search-on-typing for all your files

[Martin Ankerl]

Hi all,

I have created a little application that indexes a given directory,
and then allows to quickly search this index with regular expressions.
The motivation behind this app was that someone thought this had to be
in C++ to be fast, so I proved him wrong: search-on-typing with more
than 500,000 indexed files is easily possible

I have tried to make this actually useful, so it is possible to define
rules when clicking on a file. An example is included

* Hierarchical presented search results
* Search-on-typing
* Define rules to execute on a click

Have a look, and tell me what you think!

Get it here:

It is public domain, do whatever you want with it, but don't sue me.

class String
def levenstein(other, ins=2, del=2, sub=1)
# ins, del, sub are weighted costs
return nil if self.nil?
return nil if other.nil?
... proceed to calculate Levenstein distance between self and other
end
end

I don't understand, what is this line for:

return nil if self.nil?

Can self.nil? ever evaluate to true in a method of String???

Best regards,

Hi all,
Moin!

Have a look, and tell me what you think!

It looks nice, but you should state that it searches in file names and
not file contents somewhere.

I think that you could further simplify the code by using Find.find().
It's part of the Standard Ruby and can be used to recursively iterate
over directories / files. (It is defined in 'find.rb')

It looks like a bug -- the only Object that returns true on .nil? in
Standard Ruby is nil itself. Maybe they wanted to do self.empty? /
other.empty? instead? (But then again the Levenstein distance from an
empty string to "foo" should be 3...)

If Microsoft used Ruby, Longhorn would already be out .

I already use Find.find, it's somewhere in src/hierarchy.rb. But I
need to have a special data structure, so I have a wrapper for this.
