# cliui
[](https://travis-ci.org/yargs/cliui)
[](https://coveralls.io/r/yargs/cliui?branch=)
[](https://www.npmjs.com/package/cliui)
[](https://github.com/conventional-changelog/standard-version)
easily create complex multi-column command-line-interfaces.
## Example
```js
var ui = require('cliui')({
width: 80
})
ui.div('Usage: $0 [command] [options]')
ui.div({
text: 'Options:',
padding: [2, 0, 2, 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())
```

## Layout DSL
cliui exposes a simple layout DSL:
If you create a single `ui.row`, passing a string rather than an
object:
* `\n`: characters will be interpreted as new rows.
* `\t`: characters will be interpreted as new columns.
* `\s`: characters will be interpreted as padding.
**as an example...**
```js
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())
```
**will output:**
```shell
Usage: node ./bin/foo.js
<regex> provide a regex
<glob> provide a glob [required]
```
## Methods
```js
cliui = require('cliui')
```
### cliui({width: integer})
Specify the maximum width of the UI being generated.
### cliui({wrap: boolean})
Enable or disable the wrapping of text in a column.
### cliui.div(column, column, column)
Create a row with any number of columns, a column
can either be a string, or an object with the following
options:
* **width:** the width of a column.
* **align:** alignment, `right` or `center`.
* **padding:** `[top, right, bottom, left]`.
* **border:** should a border be placed around the div?
### cliui.span(column, column, column)
Similar to `div`, except the next row will be appended without
a new line being created.
