New User Request

[Ron Isaacson]

Hello --

I'd like to register as a CPAN contributor.

Name:   Ron Isaacson
E-mail: [EMAIL PROTECTED]
Userid: ISAACSON

I have one module ready for near-immediate release: Env::Module, a Perl
interface to modulecmd, to automate loading of modulefiles from Perl
scripts. Although the global community of module users is not huge, it
definitely does exist, and Env::Module should reduce the need for
deviant hackery.

I'm also working on a much larger project, tentatively called Xfer. Xfer
supports transferring of data between two arbitrary sources. The sources
are extensible -- currently I have Xfer::Source::CSV (for delimited text
files), Xfer::Source::DBI (for any DBD database), and Xfer::Source::Perl
(for Perl functions, called repeatedly to produce or accept data).
Anybody can write more Xfer::Source classes. You simply instantiate two
Xfer::Source objects and pass them to Xfer, which performs the transfer.
Many options are supported, such as mapping (reordering) of fields, row
callbacks, timeouts, etc. I've got an early alpha of this working, and I
would like to start releasing it for testing and feedback.

Thank you!

Hi Andreas --

Thanks for the quick reply! It seems the Env:: namespace is already in
use under Chapter 4 (user DSB has Env::Path). Env::Module is similar in
theory, although it works with modulefiles. By definition, from
www.modules.org:

  The Modules package provides for the dynamic modification of a user's
  environment via modulefiles. 

  Each modulefile contains the information needed to configure the shell
  for an application. Once the Modules package is initialized, the
  environment can be modified on a per-module basis using the module
  command which interprets modulefiles. Typically modulefiles instruct
  the module command to alter or set shell environment variables such as
  PATH, MANPATH, etc. modulefiles may be shared by many users on a
  system and users may have their own collection to supplement or
  replace the shared modulefiles

Here's an example: let's say you have several releases of xemacs
installed, and you want an easy way to choose your favorite release.
Here's a modulefile that might be called "xemacs/21.1.14":

  #%Module

  if { [file isdirectory /usr/xemacs/21.1.14/bin] } {
  prepend-path PATH /usr/xemacs/21.1.14/bin
  }

  if { [file isdirectory /usr/xemacs/21.1.14/man] } {
  prepend-path MANPATH /usr/xemacs/21.1.14/man
  }

Then there's a binary, called modulecmd, which outputs eval'able code in
a variety of languages. If your shell is ksh, you might type: "eval
`modulecmd ksh load xemacs/21.1.14`" to properly configure your
environment.

Now, modulecmd supports perl as well. If I issue the command "modulecmd
perl load xemacs/21.1.14", given the above modulefile, it will spit out
something like this (well not exactly, but here's a simplified version):

  $ENV{'PATH'} = "/usr/xemacs/21.1.14/bin:" . $ENV{'PATH'};
  $ENV{'MANPATH'} = "/usr/xemacs/21.1.14/man:" . $ENV{'MANPATH'};

That's where Env::Module comes in. You say Env::Module::load
('xemacs/21.1.14') and it will run modulecmd and eval the output. (It
can also unload modules and do some other fancy stuff, like check for
errors.)

Obviously, this will only be useful to people who use modulecmd and have
some modulefiles installed. Can you recommend a chapter for this, and a
good succinct way to describe it? :-)

Hello --

I have not made any changes to this module since its initial upload a
few months ago. Can you tell me why I got this notification today? Thank
you!
