|
|
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: 40, |
|
padding: [0, 4, 0, 4] |
|
}, |
|
{ |
|
text: "the file to load", |
|
width: 25 |
|
}, |
|
{ |
|
text: "[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. |
|
* ` `: 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]`. |
|
|
|
### cliui.span(column, column, column) |
|
|
|
Similar to `div`, except the next row will be appended without |
|
a new line being created.
