Hi,
I've just finished a simple web based spellcheck application
based on ispell, it's written as perl module which just call
ispell on every request (actually keeps it open afert first request).
The bad thing is N users used spellcheck there are N running
useless ispells and it is not good I think.
I think as sort of spellcheck server should be written which can fork
accordingly to user requests.
Where can I find sample code (skeleton code) for such server?
Would you recommend any other method?

Why not simply rewrite ispell in Perl and make your module do that instead
of needing an external server ? I think it has been at least partially done
(well, there's at least spell). See http://doriath.perl.com/ppt/what.html

You want to write an XS interface to the aspell API. That would be far
lighter. I thought about doing this a while back, but decided we didn't
need it for our current project.

Have you checked CPAN?

It looks like that simply calls out to the ispell program.

How funny. I just spent the last several days working on the exact
same code. I used Lingua::Ispell to communicate with ispell. It's
pretty good, but I think it could be written much more cleanly. (I
know, I know patches are always welcome :) I spent a long time last
week closely examing the source for Lingua::Ispell because I
encountered what turned out to be a bug in mod_perl versions 1.23 and
higher built with Perl 5.6.0 where the STDIN and STDOUT get very, very
confused. You could always take a look at that code to get a feel for
where to start. I began hacking on my own implementation, playing
with IPC::Open2 and IO::* modules. Very interesting stuff. Anyway,
that's what I'd recommend.
BTW, any chance I could take a look at how you solved the problems?
I'm still working on my version.

I swear, I searched CPAN before posting the question to the conference and I
used Lingua::Ispell
in my application. But Lingua::Ispell just opens 'ispell -a' on reading and
writing for every new httpd process, so it take time to open dictionaries or
switch to other language dictionary.
It provide nice interface .. but I thought that stand-alone "spell" server
would provide better performance and
used less memory.

I wrote a little server that wraps around mpg123. Maybe
the structure of this module will help you out.

Check out Daemon.pm and bin/mp3 .

Wasn't ispell ported to the PPT? If so, you could rip the source
from the perl power tools library and eliminate the external call to
ispell completely. This doesn't povide any forking or server stuff,
but I've found that solutions like that are rarely needed.
