Блогът на Фил

Идеята да мога програмно да публикувам в блога си ми хрумна когато въвеждам книги и филми в една програма каталог – gcstar. Та идеята е като въведа нова книга или нов филм вътре gcstar автоматично да публикува предефинирано съобщение за това че съм купил съответното нещо, или ако въведа коментар – да го публикува. Така ще ми спести доста време.
И понеже gcstar е писана на PERL, реших да проверя как стои въпросът с публикуване в livejournal чрез PERL.
Отидох на онлайн хранилището за pERL модули, наречено CPAN и намерих модула LJ-Simple-0.15. Чрез него програма, която публикува във вашия блог изглежда така:

use LJ::Simple;

LJ::Simple::QuickPost(
user => “test”,
pass => “test”,
entry => “Just a simple entry”,
) || die “$0: Failed to post entry: $LJ::Simple::error\n”;

Уникално, а?
Най-много ми харесва скоростта, с която се решават проблеми чрез CPAN. Трябва ти някаква функционалност, търсиш в CPAN, намираш нужния ти модул, инсталираш го, копираш примера от задължителната документация и имаш работещо решение. Гениално!

Just a simple entry

Just a simple entry

Днес реших да потърся начин да публикувам в блога си програмно чрез Python. След тестване на различни кодове успях да модифицирам този – http://hewgill.com/ljdump/ и се получи следното приложенийце, с което публикувах предишния запис:

#!/usr/bin/python
#
# ljdump.py – livejournal archiver
# Greg Hewgill <greg@hewgill.com> http://hewgill.com
# Version 1.2
#
# $Id: ljdump.py 17 2006-09-08 08:46:56Z greg $
#
# This program reads the journal entries from a livejournal (or compatible)
# blog site and archives them in a subdirectory named after the journal name.
#
# The configuration is read from “ljdump.config”. A sample configuration is
# provided in “ljdump.config.sample”, which should be copied and then edited.
# The configuration settings are:
#
#   server – The XMLRPC server URL. This should only need to be changed
#            if you are dumping a journal that is livejournal-compatible
#            but is not livejournal itself.
#
#   username – The livejournal user name. A subdirectory will be created
#              with this same name to store the journal entries.
#
#   password – The account password. This password is never sent in the
#              clear; the livejournal “challenge” password mechanism is used.
#
# This program may be run as often as needed to bring the backup copy up
# to date. Both new and updated items are downloaded.
