NAME¶
rhino - invokes the JavaScript shell for running scripts in batch mode or
interactive
SYNOPSIS¶
rhino [options] script_filename_or_url
[script_arguments]
DESCRIPTION¶
This manual page documents briefly the
rhino command. This manual page
was written for the Debian distribution because the original program does not
have a manual page. It is written according to the html documentation.
rhino is a start script for the rhino JavaScript shell which provides a
simple way to run scripts in batch mode or an interactive environment for
exploratory programming.
OPTIONS¶
- -e script_source
- Executes script_source as a JavaScript script.
- -f script_filename_or_url
- Reads script_filename_or_url content and execute it as a
JavaScript script.
- -opt, -O optLevel
- Optimizes at level optLevel, which must be an integer
between -1 and 9. -1 means Interpretive mode is always used. 0 means no
optimizations whereas 9 means all optimizations are performed.
- -version versionNumber
- Specifies the language version to compile with. The string
versionNumber must be one of 100, 110, 120, 130, or 140. See JavaScript
Language Versions for more information on language versions.
- -strict
- Enable strict mode.
PREDEFINED PROPERTIES¶
Scripts executing in the shell have access to some additional properties of the
top-level object.
- arguments
- The arguments object is an array containing the strings of
all the arguments given at the command line when the shell was
invoked.
- help()
- Executing the help function will print usage and help
messages.
- defineClass(className)
- Define an extension using the Java class named with the
string argument className. Uses ScriptableObject.defineClass() to define
the extension.
- deserialize(filename)
- Restore from the specified file an object previously
written by a call to serialize.
- load([filename,...])
- Load JavaScript source files named by string arguments. If
multiple arguments are given, each file is read in and executed in
turn.
- loadClass(className)
- Load and execute the class named by the string argument
className. The class must be a class that implements the Script interface,
as will any script compiled by jsc.
- print([expr...])
- Evaluate and print expressions. Evaluates each expression,
converts the result to a string, and prints it.
- readFile(path[,characterCoding])
- Read given file and convert its bytes to a string using the
specified character coding or default character coding if explicit coding
argument is not given.
- readUrl(url[,characterCoding])
- Open an input connection to the given string url, read all
its bytes and convert them to a string using the specified character
coding or default character coding if explicit coding argument is not
given.
- runCommand(commandName,[arg,...][options])
- Execute the specified command with the given argument and
options as a separate process and return the exit status of the process.
For details, see JavaDoc for
org.mozilla.javascript.tools.shell.Global#runCommand.
- serialize(object,filename)
- Serialize the given object to the specified file.
- spawn(functionOrScript)
- Run the given function or script in a different
thread.
- sync(function)
- creates a synchronized function (in the sense of a Java
synchronized method) from an existing function. The new function
synchronizes on the this object of its invocation.
- quit()
- Quit shell. The shell will also quit in interactive mode if
an end-of-file character is typed at the prompt.
- version([number])
- Get or set JavaScript version number. If no argument is
supplied, the current version number is returned. If an argument is
supplied, it is expected to be one of 100, 110, 120, 130, or 140 to
indicate JavaScript version 1.0, 1.1, 1.2, 1.3, or 1.4 respectively.
