#
# Shorten URLs with own HTTP server.
# (this script requires Python >= 2.6)
#
# How does it work?
#
# 1. The URLs displayed in buffers are shortened and stored in memory (saved in
# a file when script is unloaded).
# 2. URLs shortened can be displayed below messages, in a dedicated buffer, or
# as HTML page in your browser.
# 3. This script embeds an HTTP server, which will redirect shortened URLs
# to real URL and display list of all URLs if you browse address without URL key.
# 4. It is recommended to customize/protect the HTTP server using script options
# (see /help urlserver)
#
# Example after message:
#
# FlashCode | look at this: http://test.server.com/this-is-a-long-url
# | [ http://myhost.org:1234/8aK ]
#
# Example inside message:
#
# FlashCode | look at this: http://test.server.com/this-is-a-long-url [ http://myhost.org:1234/8aK ]
#
# List of URLs:
# - in WeeChat: /urlserver
# - in browser: http://myhost.org:1234/
#
# History:
# 2013-12-09, WakiMiko
# version 1.7: use HTTPS for youtube embedding
# 2013-12-09, Sebastien Helleu <flashcode@flashtux.org>:
# version 1.6: add reason phrase after HTTP code 302 and empty line at the end
# 2013-12-05, Sebastien Helleu <flashcode@flashtux.org>:
# version 1.5: replace HTTP 301 by 302
# 2013-12-05, Sebastien Helleu <flashcode@flashtux.org>:
# version 1.4: use HTTP 301 instead of meta for the redirection when
# there is no referer in request
# 2013-11-29, Felix Eckhofer <felix@tribut.de>
# version 1.3: - make it possible to run reverse proxy in a subdirectory by
# generating relative links and using the <base> tag. to use this, set
# http_hostname_display to 'domain.tld/subdir'.
# - mention favicon explicitly (now works in subdirectories, too).
# - update favicon to new weechat logo.
# - set meta referrer to never in redirect page, so chrome users'
# referrers are hidden, too
# - fix http_auth in chrome and other browsers which send header names
# in lower case
# 2013-05-04, Thomas Kindler <mail_weechat@t-kindler.de>
# version 1.2: added a "http_scheme_display" option. This makes it possible to run
# the server behind a reverse proxy with https:// URLs.
# 2013-03-25, Hermit (@irc.freenode.net):
# version 1.1: made links relative in the html, so that they can be followed when accessing
# the listing remotely using the weechat box's IP directly.
# 2012-12-12, WillyKaze <willykaze@willykaze.org>:
# version 1.0: add options "http_time_format", "display_msg_in_url" (works with relay/irc),
# "color_in_msg", "separators"
# 2012-04-18, Filip H.F. "FiXato" Slagter <fixato+weechat+urlserver@gmail.com>:
# version 0.9: add options "http_autostart", "http_port_display"
# "url_min_length" can now be set to -1 to auto-detect minimal url length
# Also, if port is 80 now, :80 will no longer be added to the shortened url.
# 2012-04-17, Filip H.F. "FiXato" Slagter <fixato+weechat+urlserver@gmail.com>:
# version 0.8: add more CSS support by adding options "http_fg_color", "http_css_url",
# and "http_title", add descriptive classes to most html elements.
# See https://raw.github.com/FiXato/weechat_scripts/master/urlserver/sample.css
# for a sample css file that can be used for http_css_url
# 2012-04-11, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.7: fix truncated HTML page (thanks to xt), fix base64 decoding with Python 3.x
# 2012-01-19, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.6: add option "http_hostname_display"
# 2012-01-03, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.5: make script compatible with Python 3.x
# 2011-10-31, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.4: add options "http_embed_youtube_size" and "http_bg_color",
# add extensions jpeg/bmp/svg for embedded images
# 2011-10-30, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.3: escape HTML chars for page with list of URLs, add option
# "http_prefix_suffix", disable highlights on urlserver buffer
# 2011-10-30, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.2: fix error on loading of file "urlserver_list.txt" when it is empty
# 2011-10-30, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.1: initial release
