DESCRIPTION

acorn is a utility to parse a JavaScript file from the command line. It accepts as arguments the input file. The utility spits out the syntax tree as JSON data.

OPTIONS

--ecma3, --ecma5, --ecma6, --ecma7, ..., --ecma2015, --ecma2016
Sets the ECMAScript version to parse. Default is version 7.
--tokenize
Tokenizer mode of the parser.
--locations
Attaches a "loc" object to each node with "start" and "end" subobjects, each of which contains the one-based line and zero-based column numbers in {line, column} form.
--allow-hash-bang
If enabled, skip the leading hashbang line.
--compact
No whitespace is used in the AST output.
--silent
Do not output the AST, just return the exit status.
--module
Indicates the code shouldn't be parsed as a script but as a module. This influences global strict mode and 'import' and 'export' declarations.
--help
Print the usage information and quit.
