colm v0.1.1

colm

Column formatter for terminal applications (Pronouced "column")

About

colm is a column formatter for text designed to be written to standard-out in the terminal. It came to be in light of too few options to format and align columns of text in the terminal.

Usage

colm takes an array of arrays: a group of rows. Each row is expected to be an array of strings, which are mapped to columns. colm will try to adjust column widths automatically so that the text fits perfectly in the terminal, but these can be overidden.

const formatColumns = require("colm");
const { bold } = require("chalk"); // colours and styles

console.log(formatColums([
    ["NodeJS Version",  "Supports Destructuring",   "Released"].map(bold),
    ["8.x",             "Yes",                      "2017-05-30"],
    ["7.x",             "Yes",                      "2016-10-25"],
    ["6.x",             "Yes",                      "2016-04-26"],
    ["5.x",             "No",                       "2015-10-29"],
    ["4.x",             "No",                       "2015-09-08"]
]));
