Expand description

Describes how to strip a transparent wrapper command to find the inner command.

Each wrapper has different flag semantics. This struct captures just enough to correctly skip past the wrapper and its flags to the real command. Designed for deserialization from config files — consumers load specs from JSON/TOML/YAML and pass them to [resolve_command_with].

Fields§

§name: String

Command name to match (basename, e.g., “sudo”).

§short_value_flags: Vec<String>

Short flags that consume the next token as a value (e.g., ["-u", "-g"]).

§long_value_flags: Vec<String>

Long flags that consume the next token as a value (e.g., ["--user", "--group"]).

§unanalyzable_flags: Vec<String>

Flags whose presence makes the entire invocation unanalyzable. Example: env -S executes its value as a command string (eval-equivalent).

§skip_env_assignments: bool

Whether to skip leading KEY=VALUE tokens after the wrapper (env-style).

§has_terminator: bool

Whether -- terminates flag processing for this wrapper.

§skip_positionals: usize

Number of leading positional arguments to skip before the inner command.

Some wrappers require mandatory positional args before the command: timeout DURATION cmd, chrt PRIORITY cmd, taskset MASK cmd. Set this to the number of positionals to consume before treating the next non-flag token as the inner command.
