Combine source code with AST Node.

Installation

npm install tagged-template-to-ast

Usage

`toAST` : AST

toAST tag function help to inline AST Node to source code.

toAST`var foo = ${ASTNode}`; // return AST

Example:

import toAST from "tagged-template-to-ast"
// `function(){}` expression
var nodeForInline = {
    "type": "FunctionExpression",
    "id": null,
    "params": [],
    "defaults": [],
    "body": {
        "type": "BlockStatement",
        "body": []
    },
    "generator": false,
    "expression": false
};
var astNode = toAST`var a = ${nodeForInline};`;
// astNode is the AST of  `var a = function (){};`

Combine code with AST Node.

import {parse} from "esprima"
import toAST from "tagged-template-to-ast"
var nodeForInline = parse('"string"');
var astNode = toAST`var a = ${nodeForInline}`;
// astNode is the AST of `var a = "string";`

Could inline to body block too!

import {parse} from "esprima"
import toAST from "tagged-template-to-ast"
import astEqual from "ast-equal"
var aNodeForBody = parse("sum(1);");
var astNode = toAST`if(true){
    ${aNodeForBody}
}`;
var expected = `if(true){
    sum(1);
}`;
// test helper to assert JavaScript AST equality.

astEqual(astNode, expected);
