Cherow CLI

Command line interface for Cherow ECMAScript parser.

This package can be used to parse a file from the command line. By default it accepts as arguments a input file, but this can be changed with the s flag which allows you to pass in code as in the V8 REPL.

The CLI conforms to the standard ECMAScript® 2019 (ECMA-262 9th Edition) language specification (draft)

Usage

Install it either global or locale, and type cherow from the command line. The syntax tree will be printed as JSON data.

 
// Source code
cherow -s -l function foo() {}
 
// Source file
cherow -l foo.js
