Struct EvalContext 

pub struct EvalContext {
    pub home: String,
    pub project: Option<String>,
    pub real_home: Option<String>,
    pub real_project: Option<String>,
    pub moved_dirs: Vec<(String, String)>,
    pub cwd: String,
    pub case_insensitive_paths: bool,
}

Everything the engine needs from the environment. Supplied by the caller.

Fields

home: String

The user’s home directory, for ~ and $HOME.

project: Option<String>

The trusted project root, for ${project}. None when the session has no project the caller is willing to trust (it would be the home directory, one of its ancestors or a filesystem root): every pattern naming ${project} then matches nothing, so project-scoped allows do not apply.

real_home: Option<String>

home with its symlinks resolved, when that differs (a home on a linked volume, a Windows 8.3 short name). Patterns naming ~ match under both spellings, since the caller’s PathResolver reports paths in this one.

real_project: Option<String>

project with its symlinks resolved, when that differs (macOS /tmp → /private/tmp, ~/code → /Volumes/dev/code). Patterns naming ${project} match under both spellings, exclusions included, so a file in the project is the project’s however its path is written. A link inside the project changes nothing here: its target is checked as is.

moved_dirs: Vec<(String, String)>

Directories an environment variable moved out of the home directory (MOAT_HOME, CLAUDE_CONFIG_DIR, CODEX_HOME, CURSOR_CONFIG_DIR), as (default, moved) pairs such as ("~/.claude", "/srv/claude"). A pattern naming default or a path below it also matches the same path under moved, so rules about a host’s directory follow it when it moves.

cwd: String

The directory relative paths are taken from.

case_insensitive_paths: bool

Whether file paths compare case-insensitively, as on the default macOS and Windows file systems. Host names always do; names never do.

Implementations

impl EvalContext

pub fn spellings(&self, raw: &str) -> Vec<String>

raw expanded once per spelling of the home directory and project root it names (paths::expand_pattern), and once more per directory in Self::moved_dirs it falls under; empty when it names no location. The policy compiler (ir) lowers patterns through the same expansion, and openmoat run finds where a policy pattern points with it.

Trait Implementations

impl Clone for EvalContext

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EvalContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
