Carpenter 🛠

Documentation

Road 🗺

• Add ARGS (deno.args) carpenter
• Add OS (deno.build) carpenter
• Add STRING carpenter
• Add ARRAY carpenter
• Add SWITCH carpenter
• Add OBJECT carpenter
• Add VALUE carpenter (unknown values)
• Add more options to STRING carpenter
• Add more interconnections between various carpenters

By example

OS specific code

import { OS } from "./mod.ts";

// basic
OS.on("darwin").do(() => console.log("Hey Darwin"));
OS.on("darwin").do(() => console.log("Hey Darwin")).else(() =>
  console.log("something else")
);
// multiple clauses
let str = "";
OS.on("windows")
  .do(() => str += "Hello ")
  .do(() => str += "world");

---

Command line argument specific code

import {ARGS} from "./mod.ts";

// basic usage
ARGS.on("-h")
    .do(() => some help code here)
    .else(() => -h was not found);

// multiple flags (evaluates when all flags are set)
ARGS.on("-x", "-a")
    .do(()=> console.log("flag -x and -a was found together"))

Other carpenters

For more carpenters see documentation.

import { STRING } from "./mod.ts";

STRING("hello")
  .contains("hello").and().contains("x") // false
  .or().isOfSize(5) // true
  .do(() => console.log("OH WOW!!!!")) // true because of OR operator
;

STRING("hello")
  .adapt((prev: string) => prev += " world") // adapts the string.. you may continue with chaining after this
  .getValue(); // gets the current object value.

import { SWITCH } from "./mod.ts";

SWITCH(someValue)
  .case("one").do(() => {})
  .case("chain")
  .do(() => {})
  .do(() => {})
  .default(() => {});
