"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,

||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.

submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"

|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
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
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
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
|
||||
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
|
||||
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.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
APPENDIX: How to apply the Apache License to your work.
|
||||
|
||||
To apply the Apache License to your work, attach the following
|
||||
boilerplate notice, with the fields enclosed by brackets "[]"
|
||||
replaced with your own identifying information. (Don't include
|
||||
the brackets!) The text should be enclosed in the appropriate
|
||||
comment syntax for the file format. We also recommend that a
|
||||
file or class name and description of purpose be included on the
|
||||

The Closure Compiler performs checking, instrumentation, and
|
||||
optimizations on JavaScript code. The purpose of this README is to
|
||||
explain how to build and run the Closure Compiler.
|
||||
|
||||
The Closure Compiler requires Java 6 or higher.
|
||||
http://www.java.com/
|
||||
|
||||
|
||||
//
|
||||
// Building The Closure Compiler
|
||||
//
|
||||
|
||||
There are three ways to get a Closure Compiler executable.
|
||||
|
||||
1) Use one we built for you.
|
||||
|
||||
Pre-built Closure binaries can be found at
|
||||
http://code.google.com/p/closure-compiler/downloads/list
|
||||
|
||||
|
||||
2) Check out the source and build it with Apache Ant.
|
||||
|
||||
First, check out the full source tree of the Closure Compiler. There
|
||||
are instructions on how to do this at the project site.
|
||||
http://code.google.com/p/closure-compiler/source/checkout
|
||||
|
||||
Apache Ant is a cross-platform build tool.
|
||||
http://ant.apache.org/
|
||||
|
||||
At the root of the source tree, there is an Ant file named
|
||||
build.xml. To use it, navigate to the same directory and type the
|
||||
command
|
||||
|
||||
ant jar
|
||||
|
||||
This will produce a jar file called "build/compiler.jar".
|
||||
|
||||
|
||||
3) Check out the source and build it with Eclipse.
|
||||
|
||||
Eclipse is a cross-platform IDE.
|
||||
http://www.eclipse.org/
|
||||
|
||||
Under Eclipse's File menu, click "New > Project ..." and create a
|
||||
"Java Project." You will see an options screen. Give the project a
|
||||
name, select "Create project from existing source," and choose the
|
||||
root of the checked-out source tree as the existing directory. Verify
|
||||
that you are using JRE version 6 or higher.
|
||||
|
||||
Eclipse can use the build.xml file to discover rules. When you
|
||||
navigate to the build.xml file, you will see all the build rules in
|
||||
the "Outline" pane. Run the "jar" rule to build the compiler in
|
||||
build/compiler.jar.
|
||||
|
||||
|
||||
//
|
||||
// Running The Closure Compiler
|
||||
//
|
||||
|
||||
Once you have the jar binary, running the Closure Compiler is straightforward.
|
||||
|
||||
On the command line, type
|
||||
|
||||
java -jar compiler.jar
|
||||
|
||||
This starts the compiler in interactive mode. Type
|
||||
|
||||
var x = 17 + 25;
|
||||
|
||||
then hit "Enter", then hit "Ctrl-Z" (on Windows) or "Ctrl-D" (on Mac or Linux)
|
||||
and "Enter" again. The Compiler will respond:
|
||||
|
||||
var x=42;
|
||||
|
||||
The Closure Compiler has many options for reading input from a file,
|
||||
writing output to a file, checking your code, and running
|
||||
optimizations. To learn more, type
|
||||
|
||||
java -jar compiler.jar --help
|
||||
|
||||
You can read more detailed documentation about the many flags at
|
||||
http://code.google.com/closure/compiler/docs/gettingstarted_app.html
|
||||
|
||||
|
||||
//
|
||||
// Compiling Multiple Scripts
|
||||
//
|
||||
|
||||
If you have multiple scripts, you should compile them all together with
|
||||
one compile command.
|
||||
|
||||
java -jar compiler.jar --js=in1.js --js=in2.js ... --js_output_file=out.js
|
||||
|
||||
The Closure Compiler will concatenate the files in the order they're
|
||||
passed at the command line.
|
||||
|
||||
If you need to compile many, many scripts together, you may start to
|
||||
run into problems with managing dependencies between scripts. You
|
||||
should check out the Closure Library. It contains functions for
|
||||
enforcing dependencies between scripts, and a tool called calcdeps.py
|
||||
that knows how to give scripts to the Closure Compiler in the right
|
||||
order.
