| 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. --rjray |

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.
