ingredients is a JavaScript parser used in recipes.
Heavily based on acorn and acorn-jsx, thanks to the awesome work of @RReverser and @marijnh.
Significant diversions are expected to occur in the future such as streaming, EBNF definitions, sweet.js integration, interspacial parsing and more.
ingredients.parse(code, [options])allowImportExportEverywhere: By default, import and export
declarations can only appear at a program's top level. Setting this
option to true allows them anywhere where a statement is allowed.
allowReturnOutsideFunction: By default, a return statement at
the top level raises an error. Set this to true to accept such
code.
allowSuperOutsideMethod TODO
sourceType: Indicate the mode the code should be parsed in. Can be
either "script" or "module".
sourceFilename: Correlate output AST nodes with their source filename. Useful when generating code and source maps from the ASTs of multiple input files.
plugins: Array containing the plugins that you want to enable.
ingredients generates AST according to Babel AST format. It is based on ESTree spec with the following deviations:
directives field with Directive and DirectiveLiteralAST for JSX code is based on Facebook JSX AST with the addition of one node type:
JSXTextrequire("ingredients").parse("code", {
// parse in strict mode and allow module declarations
sourceType: "module",
plugins: [
// enable jsx and flow syntax
"jsx",
"flow"
]
});
