@protobufjs/codegen
===================
[![npm](https://img.shields.io/npm/v/@protobufjs/codegen.svg)](https://www.npmjs.com/package/@protobufjs/codegen)
A minimalistic code generation utility.
API
---
* **codegen([functionParams: `string[]`], [functionName: string]): `Codegen`**<br />
Begins generating a function.
* **codegen.verbose = `false`**<br />
When set to true, codegen will log generated code to console. Useful for debugging.
Invoking **codegen** returns an appender function that appends code to the function's body and returns itself:
* **Codegen(formatString: `string`, [...formatParams: `any`]): Codegen**<br />
Appends code to the function's body. The format string can contain placeholders specifying the types of inserted format parameters:
* `%d`: Number (integer or floating point value)
* `%f`: Floating point value
* `%i`: Integer value
* `%j`: JSON.stringify'ed value
* `%s`: String value
* `%%`: Percent sign<br />
* **Codegen([scope: `Object.<string,*>`]): `Function`**<br />
Finishes the function and returns it.
* **Codegen.toString([functionNameOverride: `string`]): `string`**<br />
Returns the function as a string.
Example
-------
```js
var codegen = require("@protobufjs/codegen");
var add = codegen(["a", "b"], "add") // A function with parameters "a" and "b" named "add"
("// awesome comment") // adds the line to the function's body
("return a + b - c + %d", 1) // replaces %d with 1 and adds the line to the body
({ c: 1 }); // adds "c" with a value of 1 to the function's scope
console.log(add.toString()); // function add(a, b) { return a + b - c + 1 }
console.log(add(1, 2)); // calculates 1 + 2 - 1 + 1 = 3
