Function Documentation

main()

fn main

(

)

The main execution loop of the Phasor Shell.

• The main function performs the following steps in an infinite loop:

1. Displays a prompt containing the current working directory (fcd).
2. Reads user input from standard input (gets).
3. Trims the input and checks for the "exit" command.
4. Dispatches the command to the underlying operating system (sys_execute).

• Returns

  int Returns 0 on successful termination via 'exit'.

trim()

fn trim

(

s:string

)

-> string

A simple interactive shell implementation for the Phasor VM.

• This script provides a basic Command Line Interface (CLI) that allows users to execute system commands, navigate the file system, and interact with the Phasor environment. It demonstrates the use of standard library modules for I/O, string manipulation, and system execution.

Removes leading and trailing whitespace from a string.

• Iterates through the input string to strip space characters (' ') from both the beginning and the end of the text.

• Parameters

  s	The input string to be trimmed.

  Returns

  string A new string with whitespace removed.
