maintenance: Remove cssjanus.py
Follows-up r55510 (aa4d684a82) which added it for use with the
Vector stylesheets at times where we didn't have CSSJanus.php.
This has been unused since we introduced ResourceLoader and the
PHP-port of CSSJanus.

||||
form, that is based on (or derived from) the Work and for which the

|
||||
the Derivative Works; and
|

(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must

||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed

||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,

|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and

||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||

|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||

|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|

|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|

of your accepting any such warranty or additional liability.

_Flips CSS from LTR to an RTL orienation and vice-versa_
|
||||
|
||||
Author: `Lindsey Simon <elsigh@google.com>`
|
||||
|
||||
==Introduction==
|
||||
|
||||
CSSJanus is CSS parser utility designed to aid the conversion of a website's
|
||||
layout from left-to-right(LTR) to right-to-left(RTL). 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?
|
||||
|
||||

"""Converts a LeftToRight Cascading Style Sheet into a RightToLeft one.
|
||||
|
||||
This is a utility script for replacing "left" oriented things in a CSS file
|
||||
like float, padding, margin with "right" oriented values.
|
||||
It also does the opposite.
|
||||
The goal is to be able to conditionally serve one large, cat'd, compiled CSS
|
||||
file appropriate for LeftToRight oriented languages and RightToLeft ones.
|
||||
This utility will hopefully help your structural layout done in CSS in
|
||||
terms of its RTL compatibility. It will not help with some of the more
|
||||
complicated bidirectional text issues.
