Command-line javascript interpreter.

Usage

Overview

This manual page documents briefly the jsc command.

jsc is a command-line utility that allows you to run JavaScript programs outside of the context of a web browser. It is primarily used as part of the test harness for validating the JavaScript portions of WebKit, but can also be used as a scripting tool.

jsc can be run in an interactive mode to test out JavaScript expressions, or it can be passed one or more files to run similar to invoking a Perl or Python script.

Options

-e: Evaluate argument as script code.

-f: Specifies a source file (deprecated).

-h, --help: Shows summary of command-line options.

-i: Enables interactive mode (default if no files are specified).

-p file: Outputs profiling data to a file.

-s: Installs signal handlers that exit on a crash.

-x: Output exit code before terminating.

--options: Dumps all JSC VM options and exits.

--dumpOptions: Dumps all JSC VM options before continuing.

--<jsc VM option>=<value>: Sets the specified JSC VM option.
