ch cli

The ch CLI is used for internal testing of ChakraCore but can be used as a standalone JS shell host with minimal capabilities. To facilitate testing, a few host capabilities beyond the scope of ECMAScript standard (e.g. loading files) are also provided in ch.

Basic usage

ch [-v|-version] [-h|-help|-?] <source file> [options]

Common options

• -args and -endargs Used to pass arguments to the script. They can be consumed using the WScript.Arguments array object.

Usage example:

test.js:

console.log(WScript.Arguments[0])
console.log(WScript.Arguments[1])

execution:

$ ch test.js -args hello world -endargs
hello
world

Host APIs

• WScript.LoadScriptFile Loads a JS script from the file system. It takes relative paths to CWD.
