• ssh: Remote SSH execution

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

Enums

ShellQuotingStyle

Quoting dialect of the shell that will run a rebuilt command line.

Functions

build_command_string

Rebuild a shell command line from the argv the user typed, for the host shell (issue #164).

build_command_string_with

Rebuild a shell command line from the argv the user typed, for a given shell dialect.

build_display_command

Build a display string that shows the argument boundaries the user typed (issues #91, #164).

build_shell_with_args_cmd_args

Build argv for a shell-with-c command; everything after -c is one script argument.

command_name

First word of a command line, used for failure reports and log headers.

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

True if command is a bare shell invocation (no -c); avoids bash-inside-bash (issue #84).

is_shell_invocation_with_args

True if command is a shell invocation with -c (e.g. bash -i -c "cmd"); avoids double-wrapping (issue #91).

quote_shell_arg

Quote one argv element for the host shell (issue #164).

quote_shell_arg_with

Quote one argv element so the target shell parses it back as exactly that element (issue #164).

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

split_shell_words

Split a command line into shell words for the host shell dialect.

split_shell_words_with

Split a command line into shell words, reversing quote_shell_arg_with for the same dialect: a POSIX shell escapes with a backslash, PowerShell has no backslash escape (it is a path separator) and writes a literal quote as a doubled one.

to_shell_words

Split a command into words, falling back to whitespace splitting when quoting is unbalanced.

wrap_command_with_user

Wrap command with sudo -u if user option is specified
