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:

// 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
