```sh
npm install @push.rocks/smartshell --save
```
Or if you prefer using Yarn:
```sh
yarn add @push.rocks/smartshell
```
Ensure that you have TypeScript and the related dependencies installed as well since `@push.rocks/smartshell` is designed to work with TypeScript.
## Usage
Use TypeScript for best in class instellisense.
The `@push.rocks/smartshell` package simplifies running shell commands within Node.js applications by wrapping these commands within promises. This approach enhances the readability and maintainability of code that relies on shell execution, making it particularly useful in automation scripts, build processes, and any scenario where interaction with the system shell is required.
## Contribution
### Getting Started with `@push.rocks/smartshell`
We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
First, ensure that you import `Smartshell` from `@push.rocks/smartshell` using ESM syntax in your TypeScript file:
For further information read the linked docs at the top of this readme.
```typescript
import { Smartshell } from '@push.rocks/smartshell';
```

### Creating a Smartshell Instance
Before executing any shell command, you need to create an instance of `Smartshell`. The constructor accepts configuration options such as the shell executor (`bash` or `sh`), and optionally, paths to source files and directories to include in the shell’s environment.
```typescript
const smartShellInstance = new Smartshell({
executor: 'bash', // or 'sh'
});
```
### Executing Commands
#### Basic Execution
To execute a shell command, use the `exec` method. This method returns a promise that resolves with an execution result object containing `exitCode` and `stdout`.
```typescript
(async () => {
const result = await smartShellInstance.exec('echo "Hello, SmartShell"');
console.log(result.stdout); // Outputs: Hello, SmartShell
})();
```
#### Silent Execution
If you prefer not to display the output in the console, use `execSilent`:
```typescript
(async () => {
const result = await smartShellInstance.execSilent('ls');
console.log(result.stdout); // Outputs the list of files and directories
})();
```
#### Strict Execution
For scenarios where an execution error should immediately throw an exception, use `execStrict`:
```typescript
(async () => {
try {
const result = await smartShellInstance.execStrict('exit 1');
} catch (error) {
console.error('Command execution failed');
}
})();
```
#### Streaming Output
Some commands benefit from streaming output as they execute, especially long-running tasks. For these cases, use `execStreaming`:
```typescript
(async () => {
const execStreamingResult = await smartShellInstance.execStreaming('tail -f /var/log/system.log');
execStreamingResult.childProcess.stdout.on('data', (data) => {
console.log(data.toString());
});
// Remember to handle the process termination as necessary.
})();
```
### Advanced Usage
#### Executing With Custom Environment Variables
`smartshell` allows for the execution of commands within a modified environment, facilitating the use of custom variables or altered PATH values:
```typescript
(async () => {
smartShellInstance.shellEnv.addSourceFiles(['/path/to/envFile']);
smartShellInstance.shellEnv.pathDirArray.push('/custom/bin');
const result = await smartShellInstance.exec('echo $CUSTOM_VAR');
console.log(result.stdout); // Outputs the value of CUSTOM_VAR
})();
```
### Interactive Mode
For commands that require interactive terminal input (not typically recommended for automated scripts), you can use `execInteractive`:
```typescript
(async () => {
await smartShellInstance.execInteractive('npm init');
})();
```
### Waiting for Specific Output
To wait for a specific line before proceeding, you might use `execAndWaitForLine`. This is useful for waiting on a process to log a certain message:
```typescript
(async () => {
await smartShellInstance.execAndWaitForLine('npm run watch', /Compilation complete./);
console.log('The watch process has finished compiling.');
})();
```
Given the vast array of features offered by `@push.rocks/smartshell`, integrating shell operations into your TypeScript applications becomes both straightforward and powerful. By harnessing promises and async/await syntax, `smartshell` effectively streamlines shell interactions, making your code cleaner and more intuitive.
