The script was born out of -a need to convert CSS for RTL languages when tables are not being used for layout (since tables will automatically reorder TD's in RTL). -CSSJanus will change most of the obvious CSS property names and their values as -well as some not-so-obvious ones (cursor, background-position %, etc...). -The script is designed to offer flexibility to account for cases when you do -not want to change certain rules which exist to account for bidirectional text -display bugs, as well as situations where you may or may not want to flip annotations inside of the background url string. -Note that you can disable CSSJanus from running on an entire class or any -rule within a class by prepending a /* @noflip */ comment before the rule(s) -you want CSSJanus to ignore. - -CSSJanus itself is not always enough to make a website that works in a LTR -language context work in a RTL language all the way, but it is a start. - -==Getting the code== - -View the trunk at: - - http://cssjanus.googlecode.com/svn/trunk/ - -Check out the latest development version anonymously with: - -{{{ - $ svn checkout http://cssjanus.googlecode.com/svn/trunk/ cssjanus -}}} - -==Using== - -Usage: - ./cssjanus.py < file.css > file-rtl.css -Flags: - --swap_left_right_in_url: Fixes "left"/"right" string within urls. - Ex: ./cssjanus.py --swap_left_right_in_url < file.css > file_rtl.css - --swap_ltr_rtl_in_url: Fixes "ltr"/"rtl" string within urls. - Ex: ./cssjanus.py --swap_ltr_rtl_in_url < file.css > file_rtl.css - -If you'd like to make use of the webapp version of cssjanus, you'll need to -download the Google App Engine SDK - http://code.google.com/appengine/downloads.html -and also drop a "django" directory into this directory, with the latest svn -from django. You should be good to go with that setup. Please let me know -otherwise. - -==Bugs, Patches== - -Patches and bug reports are welcome, just please keep the style -consistent with the original source. If you find a bug, please include a diff -of cssjanus_test.py with the bug included as a new unit test which fails. It -will make understanding and fixing the bug easier. - -==Todo== - -* Include some helpers for some typical bidi text solutions? -* Aural CSS (azimuth) swapping? - -==Contributors== - -Additional thanks to Mike Samuel for his work on csslex.py, Andy Perelson for -his help coding and reviewing, Stephen Zabel for his help with i18n and my sanity, -and to Eric Meyer for his thoughtful input. -Thanks to Junyu Wang for the Chinese translation. -Thanks to Masashi Kawashima for the Japanese translation. -Thanks to Taaryk Taar and Tariq Al-Omaireeni for an updated Arabic translation. -Thanks to Jens Meiert for the German translation. - -==License== - -{{{ - Copyright 2008 Google Inc.
