Description:

This script is derived from one of the examples I developed for the chapter of my book that introduces the SOAP::Lite module.

It posts a journal entry to the journal system at use.perl.org, without using the browser interface, and without faking a POST to the CGI interface. It uses instead the still-alpha SOAP interface that use.perl currently offers.

All elements of the SOAP request may be specified on the command-line, including entry subject, whether to enable comments, uid and passwd, and the option of reading the entry from a file (the default is to read from STDIN, filter-like). It also will attempt to set the authentication credentials from your Netscape cookie file. But as I said, those can be set by the command-line (and the cmd-line switch overrides the Netscape cookie).

In a first-response to this code posting, I will post a XEmacs defun (which should also work under GNU/Emacs) that I use to post from within XEmacs by selecting the text I want to upload into the region. More on that in the follow-up node.

Usage: $0 [ -m title ] [ -f file ] [ -c yes|no ] [ -C user:pass ]
where:

-m title        Provide title for the journal entry
                (default is command name-based)
-f file         Read the journal entry from FILE instead of STDIN
-c yes|no       Allow or disallow comments
                (default is to let your use.perl.org default stand)
-C user:pass    Provide authentication credentials in place of (or in
                absence of) Netscape cookie authentication. User in
                this case is UID, not nickname.
