• option.format.indent.style: Indent string. Default is 4 spaces (' ').

• option.format.indent.base: Base indent level. Default is 0.

• option.format.json: Enforce JSON format of numeric and string literals. This option is takes precedence over option.format.hexadecimal and option.format.quotes. Default is false.

• option.format.renumber: Try to generate shorter numeric literals than toString() (9.8.1). Default is false.

• option.format.hexadecimal: Generate hexadecimal a numeric literal if it is shorter than its equivalents. Requires option.format.renumber. Default is false.

• option.format.quotes: Delimiter to use for string literals. Accepted values are: 'single', 'double', and 'auto'. When 'auto' is specified, escodegen selects a delimiter that results in a shorter literal. Default is 'single'.

• option.format.escapeless: Escape as few characters in string literals as necessary. Default is false.

• option.format.compact: Do not include superfluous whitespace characters and line terminators. Default is false.

• option.format.parentheses: Preserve parentheses in new expressions that have no arguments. Default is true.

• option.format.semicolons: Preserve semicolons at the end of blocks and programs. Default is true.

• option.parse: Mozilla Parser API compatible parse function. If it is provided, generator tries to use the 'raw' representation. See esprima raw information. Default is null.

• option.comment: If comments are attached to AST, escodegen is going to emit comments to output code. Default is false.
