OS

This page documents the changes & additions to the os library in Pluto, which is built on top of Lua 5.4's.

`os.platform`

os.platform is a global string containing the host platform. Can be "windows", "wasm", "linux", "macos", "android", or "unknown".

`os.arch`

os.arch is a global string containing the host CPU architecture as well as the bit width, separated by a comma. For example, it would be x86, 64-bit for x86_64, arm, 64-bit for ARM64, and wasm, 32-bit for a typical WebAssembly environment.

`os.sleep`

Parameters

The amount of milliseconds to sleep for.

Example

pluto
os.sleep(1000) -- Pause this thread for 1000ms.

`os.nanos`, `os.micros`, `os.millis`, `os.seconds`

All of these return their respective times since implementation-specific epoch.

`os.unixseconds`

Returns seconds since UNIX epoch.

`os.rename`, `os.remove`

Although we'd rather these functions be in the IO library, these Lua variants are retained, but modified to assume UTF-8 path encoding for the same cross-platform consistency the IO library has.
