Main scripts is mod.ts.
Input is a module that is inspired by pythons input method. It allows writing to a Writer (like stdout) and waiting for input separated by a newline by reading from a Reader (such as stdin).
The input method allows you to prompt the user on stdout and wait for a line of input on stdin. Throws on End of File.
Default signature:
type input = async (output?: string) => Promise<string>input example:
import { input } from "https://raw.githubusercontent.com/johnsonjo4531/pythonic_input/0.0.0/input.ts";
(async () => {
console.log("-- DENO ADDER --");
// will throw if it hits End of File...
const num1 = await input("Enter a number: ");
const num2 = await input("Enter another number: ");
console.log(`${num1} + ${num2} = ${Number(num1) + Number(num2)}`);
})();The inputNullable method allows you to prompt the user on stdout and wait for a line of input on stdin. Returns null on End of File.
Default signature:
type inputNullable = async (output?: string) => Promise<string | null>inputNullable example:
import { inputNullable } from "https://raw.githubusercontent.com/johnsonjo4531/pythonic_input/0.0.0/input.ts";
(async () => {
console.log("-- DENO ADDER --");
// will throw if it hits End of File...
const num1 = await inputNullable("Enter a number: ");
const num2 = await inputNullable("Enter another number: ");
console.log(`${num1} + ${num2} = ${Number(num1) + Number(num2)}`);
})();The inputReader method allows you to create an input or inputNullable method of your own with different different input and output files besides stdin and stdout.
inputReader example:
import { inputReader } from "https://raw.githubusercontent.com/johnsonjo4531/pythonic_input/0.0.0/input.ts";
// you could substitute Deno.stdin and Deno.stdout with any open file (with appropriate permissions)
// or with a Deno Reader and Writer.
const input = inputReader(Deno.stdin, Deno.stdout, {
// optional options can go here
});
// the below produces the same output as the input example
(async () => {
console.log("-- DENO ADDER --");
// get the next line throws if it reaches the EOF
const num1 = String(await input("Enter a number: "));
const num2 = String(await input("Enter another number: "));
console.log(`${num1} + ${num2} = ${Number(num1) + Number(num2)}`);
})();An example using the input method is given in ./examples/input.ts
Try it out
$ deno https://raw.githubusercontent.com/johnsonjo4531/pythonic_input/0.0.0/examples/input.tsHere's an example run of the program
$ deno https://raw.githubusercontent.com/johnsonjo4531/pythonic_input/0.0.0/examples/input.ts
-- DENO ADDER --
Enter a number: 2
Enter another number: 3
2 + 3 = 5See the ./examples/cat.ts for an example to run. You can compare this with the cat implementation on deno's examples in the std library.
