Info:
=====
Google's JavaScript library for parsing, formatting, and validating
international phone numbers.


How to setup:
=============
1.  Checkout closure-library, closure-compiler, closure-linter and python-gflags
    next to libphonenumber:

e.g.
git clone https://github.com/googlei18n/libphonenumber/
git clone https://github.com/google/closure-library/
git clone https://github.com/google/closure-compiler.git
svn checkout http://closure-linter.googlecode.com/svn/trunk/ ~/src/closure-linter
svn checkout http://python-gflags.googlecode.com/svn/trunk/ ~/src/python-gflags

(If you don't checkout the dependencies next to libphonenumber:
a. change the path of the <script src=""> in the html pages to point to wherever
   base.js is located
b. update javascript/build.xml with the correct paths)

2.  Run the unit tests to make sure everything is working. Open the following
pages with your web browser:
  javascript/i18n/phonenumbers/phonenumberutil_test.html
  javascript/i18n/phonenumbers/asyoutypeformatter_test.html

3.  Run the demo: javascript/i18n/phonenumbers/demo.html


How to compile:
===============
1.  Build Closure's compiler.jar:

e.g.
ant -f ~/src/closure-compiler/build.xml

2.  Compile the demo.js and all its dependencies to one file: demo-compiled.js:

ant -f javascript/build.xml compile-demo

3.  Run the compiled demo: javascript/i18n/phonenumbers/demo-compiled.html


How to use:
===========
To use and compile the library in your own project, use the
javascript/i18n/phonenumbers/demo.js as an example. You will need to
goog.exportSymbol all the methods you use in your html so that the compiler
won't rename them. You can then invoke the compiler similarly to how the
compile-demo ant target in javascript/build.xml invokes it.


How to update:
==============
The JavaScript library is ported from the Java implementation (revision 536).
When the Java project gets updated follow these steps to update the JavaScript
project:

1.  If the protocol buffers (phonemetadata.proto and phonenumber.proto)
    have changed:
  a.  Manually update the .pb.js files with the changes of the .proto files.
  b.  Manually update the toJsArray() Java methods in
      tools/java/java-build/src/com/google/i18n/phonenumbers/BuildMetadataJsonFromXml.java
  c.  Build tools/java/java-build/target/java-build-1.0-SNAPSHOT-jar-with-dependencies.jar
      by running:
      mvn -f tools/java/java-build/pom.xml package

2.  If the phone number metadata in the XML format has changed
    (resources/PhoneNumberMetadata.xml)
    run the following commands to regenerate metadata.js and
    metadatafortesting.js:

    ant -f java/build.xml build-js-metadata

3.  Manually port any changes of the Java code to the JavaScript code:
      PhoneNumberUtil.java => phonenumberutil.js
      AsYouTypeFormatter.java => asyoutypeformatter.js
      PhoneNumberUtilTest.java => phonenumberutil_test.js
      AsYouTypeFormatterTest.java => asyoutypeformatter_test.js

4.  Run the Closure Compiler to get your changes syntax and type checked.
    This will also generate demo-compiled.js used by demo-compiler.html
    (TODO: Use target "compile" rather than "compile-demo" once
     visibility issues for getExtractedNationalPrefix_ have been resolved):

    ant -f javascript/build.xml compile-demo

5.  Run the Closure Linter to lint the JavaScript files:

    ant -f javascript/build.xml lint


TODO:
=====
Port functionality to extract phone-numbers from text (findNumbers).
Port offline phone number geocoder.
Enable PhoneNumberUtil to handle all digits, rather than a subset
(JavaScript has no equivalent to the Java Character.digit).
Port ShortNumberInfo.
