Modules

isolation_log

Logging and utility functions for isolation runners

isolation_screen

Screen-specific isolation helpers extracted from isolation.rs

Structs

IsolationOptions

Options for isolation

IsolationResult

Result of an isolation run

Functions

build_shell_with_args_cmd_args

Build argv for a shell-with-c command; everything after -c is joined as one argument. Reverses the join(’ ’) that collapsed the original quoted argument. Used to pass bash -i -c "nvm --version" directly as argv (issue #91 fix).

detect_shell_in_environment

Detect the best available shell in an isolation environment (docker/ssh) Tries shells in order: bash, zsh, sh Returns the shell path to use

docker_image_exists

Check if a Docker image exists locally

docker_pull_image

Pull a Docker image with output streaming

get_shell

Get the shell to use for command execution

has_tty

Check if the current process has a TTY attached

is_command_available

Check if a command is available on the system

is_interactive_shell_command

Returns true if command is a bare interactive shell invocation (no -c flag). Used to avoid double-wrapping shells in isolation environments (issue #84).

is_shell_invocation_with_args

Returns true if command is a shell invocation that includes -c (e.g. bash -i -c "cmd"). Used to pass such commands directly without double-wrapping (issue #91).

run_as_isolated_user

Run command as an isolated user (without isolation backend)

run_in_docker

Run command in Docker container

run_in_screen

Run command in GNU Screen

run_in_ssh

Run command over SSH

run_in_tmux

Run command in tmux

run_isolated

Run command in the specified isolation backend

wrap_command_with_user

Wrap command with sudo -u if user option is specified
