Implementations

impl Shell

pub fn new() -> Self

Create a new shell

pub fn run(&self) -> !

Run the shell

pub fn execute_command(&self, command_line: &str) -> CommandResult

Execute a command line.

Supports &&, ||, ; operators, pipes (|), I/O redirections (>, >>, <, <<<, 2>, 2>&1), variable expansion, alias expansion, glob pattern expansion, command substitution ($(...)), and subshell grouping ((cmd1; cmd2)).

pub fn init_console(&self) -> Result<(u32, u32), KernelError>

Initialize the console device by creating a PTY pair.

Creates a PTY master/slave pair via the PTY manager and optionally sets the terminal size. Shell output can then be routed through the PTY slave while falling back to serial when PTY is unavailable.

Returns Ok((master_id, slave_id)) on success.

pub fn get_cwd(&self) -> String

Get current working directory

pub fn set_cwd(&self, path: String) -> Result<(), KernelError>

Set current working directory

pub fn get_env(&self, name: &str) -> Option<String>

Get environment variable

pub fn set_env(&self, name: String, value: String)

Set environment variable

pub fn get_all_env(&self) -> Vec<String>

Get all environment variables

pub fn stop(&self)

Stop the shell

pub fn register_builtin(&self, command: Box<dyn BuiltinCommand>)

Register a builtin command (public API for external modules)

pub fn register_builtins_batch(&self, commands: Vec<Box<dyn BuiltinCommand>>)

Register multiple builtin commands at once
