=head1 NAME
sp_poster.pl - retrieves and/or updates user's scratchpad
=head1 SYNOPSIS
sp_poster.pl -file [-user -pass -append -prepend -code]
Options:
-user -u user's name
-pass -p user's password
-file -f file to post (- for STDIN)
-read -r returns current contents; no update performed
-append -app appends file to existing scratchpad
-prepend -pre prepends file to existing scratchpad
-public -pub makes scratchpad public
-code -c wraps entire file in code tags
-help -h -? brief help message
=head1 DESCRIPTION
B<This program> will read the given input file and post it to your scr
+atchpad.
Simply specify - for the filename to read from STDIN. Your user name i
+s
required, as well as the password. These values can be hard-coded into
+ the code
in the appropriate place if you know that no one else will see this sc
+ript. If
the username and/or password are not provided with switches and the va
+lues are
not hardcoded in the script, you will be prompted on STDIN for these v
+alues.
Also required is the file to be uploaded to your scratch pad, unless y
+ou
specify the read option, which will print your current scratch pad to
+STDOUT
without uploading any new content.
Not required is the code option, which will wrap the entire file to be
+ posted
with code tags; the append option, which will append the file to be po
+sted; and
the prepend option, which will prepend the file to be posted. If eithe
+r the
append or prepend option are true, two requests will be posted - one t
+o
retrieve the current contents of your scratch pad and one to post the
+new
contents. Make sure you spell append and prepend correctly, or else y
+ou will
wipe out your scratchpad with the new content.
The public option makes your scratchpad publicly viewable by everyone
+else. If
you wish to make your scratchpad public, you must provide this switch
+each time
you update your scratchpad with this script. Not providing the public
+option
on any single script execution will result in your scratchpad being ma
+de
private. The exception is if you pass the read option -- no changes wi
+ll be
made to the scratchpad.
=head1 EXAMPLES
=over 4
=item backup scratchpad to an HTML file:
./sp_poster.pl -user jeffa -read > pad.html
=item post simple HTML file:
./sp_poster.pl -user jeffa -public -file=foo.html
=item append a perl script (assing code tags):
./sp_poster.pl -u jeffa -pub -f=foo.pl -c -append
=item prepend 'on the fly' STDIN content
./sp_poster.pl -u jeffa -pub -f - -pre
[type away - hit CNTRL-D when finished]
=item append errors from perl script
./foo.pl 2>&1>/dev/null | ./sp.pl -u jeffa -p pass -pub -f - -c -app
