<p>easily create complex multi-column command-line-interfaces.</p>

<h3>Example</h3>

<pre><code>
const ui = require('cliui')()

ui.div('Usage: $0 [command] [options]')

ui.div({
text: 'Options:',
padding: [2, 0, 1, 0]
})

ui.div(
{
text: "-f, --file",
width: 20,
padding: [0, 4, 0, 4]
},
{
text: "the file to load." +
chalk.green("(if this description is long it wraps).")
,
width: 20
},
{
text: chalk.red("[required]"),
align: 'right'
}
)

console.log(ui.toString())
</code></pre>

<h3>Deno/ESM Support</h3>

<p>As of <code>v7</code> <code>cliui</code> supports <a href="https://github.com/denoland/deno">Deno</a> and</p>
<p><a href="https://nodejs.org/api/esm.html#esm_ecmascript_modules">ESM</a>:</p>

<pre><code>
import cliui from "https://deno.land/x/cliui/deno.ts";

const ui = cliui({})

ui.div('Usage: $0 [command] [options]')

ui.div({
text: 'Options:',
padding: [2, 0, 1, 0]
})

ui.div({
text: "-f, --file",
width: 20,
padding: [0, 4, 0, 4]
})

console.log(ui.toString())
</code></pre>

<h3>Layout DSL</h3>

<p>cliui exposes a simple layout DSL:</p>

<p>If you create a single <code>ui.div</code>, passing a string rather than an</p>
<p>object:</p>

<ul>
<li><code>\n</code>: characters will be interpreted as new rows.</li>
<li><code>\t</code>: characters will be interpreted as new columns.</li>
<li><code>\s</code>: characters will be interpreted as padding.</li>
</ul>

<p><strong>as an example...</strong></p>

<pre><code>
var ui = require('./')({
width: 60
})

ui.div(
'Usage: node ./bin/foo.js\n' +
' <regex>\t provide a regex\n' +
' <glob>\t provide a glob\t [required]'
)

console.log(ui.toString())
</code></pre>

<p><strong>will output:</strong></p>

<pre><code>
Usage: node ./bin/foo.js
<regex> provide a regex
<glob> provide a glob [required]
</code></pre>

<h3>Methods</h3>

<pre><code>
cliui = require('cliui')
</code></pre>

<h4>cliui({width: integer})</h4>

<p>Specify the maximum width of the UI being generated.</p>
<p>If no width is provided, cliui will try to get the current window's width and use it, and if that doesn't work, width will be set to <code>80</code>.</p>

<h4>cliui({wrap: boolean})</h4>

<p>Enable or disable the wrapping of text in a column.</p>

<h4>cliui.div(column, column, column)</h4>

<p>Create a row with any number of columns, a column</p>
<p>can either be a string, or an object with the following</p>
<p>options:</p>

<ul>
<li><strong>text:</strong> some text to place in the column.</li>
<li><strong>width:</strong> the width of a column.</li>
<li><strong>align:</strong> alignment, <code>right</code> or <code>center</code>.</li>
<li><strong>padding:</strong> <code>[top, right, bottom, left]</code>.</li>
<li><strong>border:</strong> should a border be placed around the div?</li>
</ul>

<h4>cliui.span(column, column, column)</h4>

<p>Similar to <code>div</code>, except the next row will be appended without</p>
<p>a new line being created.</p>

<h4>cliui.resetOutput()</h4>

<p>Resets the UI elements of the current cliui instance, maintaining the values</p>
<p>set for <code>width</code> and <code>wrap</code>.</p>
