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.

by such Contributor that are necessarily infringed by their
|
|
||||||
Contribution(s) alone or by combination of their Contribution(s)
|
|
||||||
with the Work to which such Contribution(s) was submitted. If You
|
|
||||||
institute patent litigation against any entity (including a

||||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
|
||||||
or a Contribution incorporated within the Work constitutes direct
|
|
||||||
or contributory patent infringement, then any patent licenses

||||||
granted to You under this License for that Work shall terminate

||||||
as of the date such litigation is filed.

||||||
|
|
||||||
4. Redistribution. You may reproduce and distribute copies of the
|
|
||||||
Work or Derivative Works thereof in any medium, with or without
|
|
||||||
modifications, and in Source or Object form, provided that You
|
|
||||||
meet the following conditions:

|
||||||
|
|
||||||
(a) You must give any other recipients of the Work or

||||||
Derivative Works a copy of this License; and

|
||||||
|
|
||||||
(b) You must cause any modified files to carry prominent notices
|
|
||||||
stating that You changed the files; and
|
|
||||||
|
|
||||||
(c) You must retain, in the Source form of any Derivative Works
|
|
||||||
that You distribute, all copyright, patent, trademark, and
|
|
||||||
attribution notices from the Source form of the Work,
|
|
||||||
excluding those notices that do not pertain to any part of
|
|
||||||
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
|
|
||||||
include a readable copy of the attribution notices contained
|
|
||||||
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

|
|
||||||
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
|
|
||||||

|
|
||||||
as modifying the License.
|
|
||||||
|
|
||||||
You may add Your own copyright statement to Your modifications and
|
|
||||||
may provide additional or different license terms and conditions
|
|
||||||
for use, reproduction, or distribution of Your modifications, or
|
|
||||||
for any such Derivative Works as a whole, provided Your use,
|
|
||||||
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
|

|
|
||||||
agreed to in writing, Licensor provides the Work (and each

||||||
Contributor provides its Contributions) on an "AS IS" BASIS,

|
|
||||||
implied, including, without limitation, any warranties or conditions
|

|
||||||
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

of any other Contributor, and only if You agree to indemnify,
|
|

defend, and hold each Contributor harmless for any 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.
