Struct Environment 

pub struct Environment {
    pub home: Option<PathBuf>,
    pub working_directory: PathBuf,
    pub var_lookup: Box<dyn VarLookup>,
    pub remote: bool,
    pub verbose: bool,
}

External environment dependencies for the analysis pipeline.

Groups all values that come from the OS environment so they can be overridden in tests without manipulating env vars. Production code creates this via Environment::from_system; tests use the builder methods to inject specific values.

Fields

home: Option<PathBuf>

Home directory ($HOME). Used for ~/.rippy/config, ~/.claude/settings. None skips all home-based lookups.

working_directory: PathBuf

Working directory for the analysis (usually std::env::current_dir()).

var_lookup: Box<dyn VarLookup>

Variable lookup for static expansion resolution. Defaults to EnvLookup (real std::env::var).

remote: bool

Whether the command originates from a remote context (e.g. docker exec).

verbose: bool

Emit tracing to stderr.

Implementations

impl Environment

pub fn from_system( working_directory: PathBuf, remote: bool, verbose: bool, ) -> Self

Build from the real system environment.

pub fn for_test(working_directory: PathBuf) -> Self

Build an isolated environment for tests: no home directory, no remote, no verbose, real env-var lookup for variable resolution.

pub fn with_home(self, home: Option<PathBuf>) -> Self

Override the home directory (builder pattern).

pub fn with_var_lookup(self, var_lookup: Box<dyn VarLookup>) -> Self

Override the variable lookup (builder pattern).
