kld-text-utils

A small collection of utilities for formatting text. I use these in a number of other modules, so it's convenient to have these all in one place.

format

This function allows you to add left and right padding and to format numbers as binary, hexadecimal, or decimals.

let format = require('kld-text-utils').format;

let h = format("{0:2x}", 106);

console.log(h);
# prints '6a'

SourcePrinter

This class allows you to emit source code, making it easy to maintain and print indentation.

let SourcePrinter = require('kld-text-utils').SourcePrinter;

let printer = new SourcePrinter();

printer.println('class Hello {').increaseIndent();
printer.printlnWithIndent('say() {').increaseIndent();
printer.printlnWithIndent('console.log("hello")').decreaseIndent();
printer.printlnWithIndent('}').decreaseIndent();
printer.printlnWithIndent('}');

This would emit:

class Hello {
	say() {
		console.log("hello")
	}
}

Table

This class allows you to format columns and rows of text (and numbers) into a table format.

var table = new Table();

table.headers = ["First", "Middle", "Last", "Age"];
table.addRow(["John", "William", "Dough", 48]);
table.addRow(["Susan", "Anita", "Bandita", 56]);
table.addRow(["Joe", "Ernest", "Cummings", 8]);

console.log(table.toString());

This would emit:

First Middle  Last     Age
===== ======= ======== ===
John  William Dough     48
Susan Anita   Bandita   56
Joe   Ernest  Cummings   8
