## Install
```
npm install terminal-in-react --save
```
or if you use `yarn`
```
yarn add terminal-in-react
```
This package also depends on `react` so make sure you've already installed it.
## Usage
```jsx
import React, { Component } from 'react';
import Terminal from 'terminal-in-react';
class App extends Component {
showMsg = () => 'Hello World'
render() {
return (
window.open('https://www.google.com/', '_blank'),
showmsg: this.showMsg,
popup: () => alert('Terminal in React')
}}
descriptions={{
'open-google': 'opens google.com',
showmsg: 'shows a message',
alert: 'alert', popup: 'alert'
}}
msg='You can write anything here. Example - Hello! My name is Foo and I like Bar.'
/>
);
}
}
```
> Be careful when copying this example because it uses `window` object (`'open-google': () => window.open("https://www.google.com/", "_blank"),`) which is only available on the client-side and it will give you an error if you're doing server side rendering.
## Working
### Adding commands ✍️
To add your own command, use prop `commands` which accepts an object. This objects then maps `command name -> command function`.
Let's take an example. You want to open a website with a command `open-google`
```jsx
window.open("https://www.google.com/", "_blank")}} />
```
### Adding description of your command 💁🏼♂️
Add a description of your command using prop `description`.
```jsx
```
### Console logging
You can have the terminal watch console.log/info function and print out.
It does so by default.
```jsx
```
### Command passthrough
You can have the terminal pass out the cmd that was input
```jsx
`-PassedThrough:${cmd}: command not found`} />
```
### Async handling of commands 😎
you can also handle the result with a callback
```jsx
{
// do something async
print(`-PassedThrough:${cmd}: command not found`);
}}
/>
```
### Minimise, maximise and close the window
```jsx
```
### Hide the default options
```jsx
```
This will hide the option color, show and clear.
### Advanced commands 👨💻
You can give your commands options and get them back parsed to the method.
Using this method will also give your command a build in help output.
With the option `-h` or `--help`.
```jsx
{
print(`The color is ${args._[0] || args.color}`);
},
options: [
{
name: 'color',
description: 'The color the output should be',
defaultValue: 'white',
},
],
},
}}
/>
```
The command API has three parameters `arguments`, `print`, and `runCommand`.
- `arguments` will be an array of the input split on spaces or and object with
parameters meeting the options given as well as a `_` option with any strings given
after the options.
- `print` is a method to write a new line to the terminals output. Any string returned
as a result of a command will also be printed.
- `runCommand` is a method to call other commands it takes a string and will
attempt to run the command given
Let's take an another example -
```jsx
{
const text = args.slice(1).join(' ');
print('');
for (let i = 0; i < text.length; i += 1) {
setTimeout(() => {
runCommand(`edit-line ${text.slice(0, i + 1)}`);
}, 100 * i);
}
}
}}
/>
```
## Using plugins 🔥
[Plugin Documentation](PLUGINS.md).
We have also developed a plugin system for the `` component which helps you develop custom plugins. Here is one example of plugin which creates a fake file system called [terminal-in-react-pseudo-file-system-plugin](https://github.com/jcgertig/terminal-in-react-pseudo-file-system-plugin).
### Instantiating the plugin
```jsx
import pseudoFileSystem from 'terminal-in-react-pseudo-file-system-plugin';
const FileSystemPlugin = pseudoFileSystem();
```
or if the plugin requires config
```jsx
import NodeEvalPlugin from 'terminal-in-react-node-eval-plugin';
import pseudoFileSystemPlugin from 'terminal-in-react-pseudo-file-system-plugin';
const FileSystemPlugin = pseudoFileSystemPlugin();
...
...
```
Awesome! Right? Let us know if you make something interesting 😃
## Plugin List
- [terminal-in-react-pseudo-file-system-plugin](https://github.com/jcgertig/terminal-in-react-pseudo-file-system-plugin) : A client-side only filesystem
- [terminal-in-react-node-eval-plugin](https://github.com/jcgertig/terminal-in-react-node-eval-plugin) : used with a filesystem to evaluate js code
- [terminal-in-react-vi-plugin](https://github.com/jcgertig/terminal-in-react-vi-plugin) : used with a filesystem to edit the contents of files more easily
## More features
### Tab autocomplete
### Multiline input 🤹🏼♀️
via `shift + enter`
### Check history of your commands 🖱️
using arrow down and up keys
### Keyboard shortcuts ⌨
You can define keyboard shortcuts. They have to be grouped by os. The three available are
`win`, `darwin`, and `linux`. You can group multiple os by a `,` for example if the
shortcut was for all platforms `win,darwin,linux` would be fine as a key
```jsx
```
But you might want to specific
```jsx
```
You can mix and match
```jsx
```
The value of the shortcut should be a command to run.
## Override the top bar buttons actionHandlers
Use the prop `actionHandlers`.
The object allows for 3 methods `handleClose`, `handleMaximise`, `handleMinimise`;
Each one is a function and will pass in the default method as the first param.
Any method not passed in will use the default.
```jsx
{
// do something on close
toggleClose();
},
handleMaximise: (toggleMaximise) => {
// do something on maximise
toggleMaximise();
}
}}
/>
```
## Customization
Use
* prop `color` to change the color of the text.
* prop `outputColor` to change the color of the output text defaults to color prop.
* prop `backgroundColor` to change the background.
* prop `barColor` to change the color of bar.
* prop `prompt` to change the prompt (`>`) color.
* prop `showActions` to change if the three circles are shown.
* prop `hideTopBar` to hide the top bar altogether.
* prop `allowTabs` to allow multiple tabs.

## Troubleshooting
**Build errors when using with `create-react-app`**
Eject from `create-react-app` and use a custom webpack configuration with [`babili-webpack-plugin`](https://github.com/webpack-contrib/babili-webpack-plugin). Read more about this [here](https://github.com/facebookincubator/create-react-app/issues/984).
**Style issues when maximizing**
Set the style to `height: 100vh` on parent element.
