21 The Closure Compiler performs checking, instrumentation, and
22 optimizations on JavaScript code. The purpose of this README is to
23 explain how to build and run the Closure Compiler.
25 The Closure Compiler requires Java 6 or higher.
30 // Building The Closure Compiler
33 There are three ways to get a Closure Compiler executable.
35 1) Use one we built for you.
37 Pre-built Closure binaries can be found at
38 http://code.google.com/p/closure-compiler/downloads/list
41 2) Check out the source and build it with Apache Ant.
43 First, check out the full source tree of the Closure Compiler. There
44 are instructions on how to do this at the project site.
45 http://code.google.com/p/closure-compiler/source/checkout
47 Apache Ant is a cross-platform build tool.
48 http://ant.apache.org/
50 At the root of the source tree, there is an Ant file named
51 build.xml. To use it, navigate to the same directory and type the
56 This will produce a jar file called "build/compiler.jar".
59 3) Check out the source and build it with Eclipse.
61 Eclipse is a cross-platform IDE.
62 http://www.eclipse.org/
64 Under Eclipse's File menu, click "New > Project ..." and create a
65 "Java Project." You will see an options screen. Give the project a
66 name, select "Create project from existing source," and choose the
67 root of the checked-out source tree as the existing directory. Verify
68 that you are using JRE version 6 or higher.
70 Eclipse can use the build.xml file to discover rules. When you
71 navigate to the build.xml file, you will see all the build rules in
72 the "Outline" pane. Run the "jar" rule to build the compiler in
77 // Running The Closure Compiler
80 Once you have the jar binary, running the Closure Compiler is straightforward.
82 On the command line, type
84 java -jar compiler.jar
86 This starts the compiler in interactive mode. Type
90 then hit "Enter", then hit "Ctrl-Z" (on Windows) or "Ctrl-D" (on Mac or Linux)
91 and "Enter" again. The Compiler will respond:
95 The Closure Compiler has many options for reading input from a file,
96 writing output to a file, checking your code, and running
97 optimizations. To learn more, type
99 java -jar compiler.jar --help
101 You can read more detailed documentation about the many flags at
102 http://code.google.com/closure/compiler/docs/gettingstarted_app.html
106 // Compiling Multiple Scripts
109 If you have multiple scripts, you should compile them all together with
112 java -jar compiler.jar --js=in1.js --js=in2.js ... --js_output_file=out.js
114 The Closure Compiler will concatenate the files in the order they're
115 passed at the command line.
117 If you need to compile many, many scripts together, you may start to
118 run into problems with managing dependencies between scripts. You
119 should check out the Closure Library. It contains functions for
120 enforcing dependencies between scripts, and a tool called calcdeps.py
121 that knows how to give scripts to the Closure Compiler in the right

143 Description: A partial copy of Mozilla Rhino. Mozilla Rhino is an
144 implementation of JavaScript for the JVM. The JavaScript parser and
145 the parse tree data structures were extracted and modified
146 significantly for use by Google's JavaScript compiler.
148 Local Modifications: The packages have been renamespaced. All code not
149 relevant to parsing has been removed. A JsDoc parser and static typing
150 system have been added.
