# lavasys - System plugin for mumu language

A system and process plugin for the MuMu interpreter/Lava runtime.
This crate works with Linux, Mac, and Windows.

Features:

- `sys:command(cmdString, callback)`: runs a command in a subshell, calls back to lava and passes results to the callback.
- `sys:timestamp_ms`()` : returns unix time in milliseconds.
- `sys:timestamp_micro()` : returns unix time in microseconds.

- Includes background task management for commands.

## Usage

Load the plugin with extend:

    extend("sys")

Dynamic functions:
```mumu
// Run a command:
sys:command("ls", func (res) { printlin(res) })

// Get milliseconds since UNIX_EPOCH for time: sys:timestamp_ms()
// Get microseconds since UNIX_EPOCH for time: sys:timestamp_micro()
```

The callback for `sys.command` receives a keyed array with these keys:

- "command": String, the command executed
in shell
- "stdout": String, stdout from the command
- "stderr": String, STDOUT from the command
- "exit": Int, exit code
- "success": Bool, true if exit code = 0


## Installation

Build the package:

```
make
```

Install the library:
```s
make install
```
