  "readme": "# acorn-to-esprima\n\nSome functions to help transform an acorn/babel ast to esprima format.\n\nPrimarily for use in [babel-eslint](https://github.com/babel/babel-eslint), [babel-jscs](https://github.com/jscs-dev/babel-jscs), and [ast explorer](https://github.com/fkling/esprima_ast_explorer)\n\n**There are no dependencies** (the methods were changed to pass in dependencies instead)\n\nThe current functions exposed are:\n\n- `function attachComments(ast, comments, tokens)`\n  - This modifies the comments passed in.\n- `function toTokens(tokens, tt)`\n  - `tt` is `require(\"babel-core\").acorn.tokTypes`\n  - Converts template string tokens (`convertTemplateType`)\n  - filters out comment tokens\n  - runs `toToken` over each token\n- `function toToken(token, tt)`\n  - Sets `token.type`, `token.range`, and `token.value`\n- `function toAST(ast, traverse)`\n  - `traverse` is `require(\"babel-core\").traverse;`\n  - traverses over the ast and makes any necessary changes (usually es6+)\n- `function convertComments(comments)`\n  - Modifies `comment.type`\n\nHow to use:\n\nCheck out the parse method of https://github.com/babel/babel-eslint/blob/master/index.js\n```js\n// example\nexports.parse = function (code) {\n  var comments = opts.onComment = [];\n  var tokens = opts.onToken = [];\n\n  var ast;\n  try {\n    ast = parse(code, {\n        locations: true,\n        ranges: true\n    });\n  } catch (err) { throw err; }\n\n  tokens.pop();\n  ast.tokens = acornToEsprima.toTokens(tokens, tt);\n\n  acornToEsprima.convertComments(comments);\n  ast.comments = comments;\n  acornToEsprima.attachComments(ast, comments, ast.tokens);\n\n  acornToEsprima.toAST(ast, traverse);\n\n  return ast;\n}\n```",
