RE: Environment

[Garnier F. <Fra...@ne...>]

Hi Ryan,

I know DBI. But I dont want to use it. It's simplier to install only =
webmin
module without DBI and DBD.

I know %ENV too, but I didn't know that it's possible to 'write' in !

Now, I can do what I want.

Thanks a lot !

You may want to look at the perl DBI module.  It's purpose is to =
abstract
database accesses into one function.  You just tell it what driver to =
use
(Oracle/MySQL/Postgres) and it does the rest:

In perl, there is a hash called %ENV.  Run a test perl script:

--- SNIP ---
#!/usr/bin/perl

foreach my $k (sort keys %ENV) { print "$k =3D $ENV{$k}\n"; }
--- SNIP ---

All you need to do (to define new envars) is put new elements into the
hash by doing "$ENV{'oracle_var'} =3D 'value';".  These variables are
inherited to sub-processes, so if it's any sort of authentication token =
be
careful.  We learned this the hard way recently:

Hope this helps,
Ryan
