@protobufjs/codegen

Minimalistic code generation utility.

API

codegen([functionParams: string[]], [functionName: string]): Codegen
Begins generating a function.
codegen.verbose = false
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
Appends code to the function's body. The format string can contain placeholders specifying the type of inserted format parameters:
- %d: Integer
- %f: Floating point number
- %j: JSON.stringify'ed value
- %s: Raw string
Codegen([scope: Object.<string,*>]): Function
Finishes the function and returns it.
Codegen.toString([functionNameOverride: string]): string
Returns the function as a string.

Example

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
