Struct ConfigManager 

pub struct ConfigManager { /* private fields */ }

Configuration manager for loading and validating configurations

Implementations

impl ConfigManager

pub fn load() -> Result<Self>

Load configuration from the default locations rooted at the current directory.

pub fn load_for_session( workspace: impl AsRef<Path>, explicit_path: impl AsRef<Path>, ) -> Result<Self>

Load configuration for an interactive session with an explicit config file.

The explicit file takes the highest file-layer precedence (the same position a workspace root vtcode.toml would occupy), while the system/user global layers are still loaded underneath it. Unlike Self::load_from_file, the manager’s workspace_root remains the session workspace (not the explicit file’s parent directory), so workspace-relative config writes and project-level paths keep resolving against the workspace.

pub fn load_global() -> Result<Self>

Load only the system and user configuration layers.

This is used by global configuration commands that must honor legacy and XDG search precedence without accidentally importing the current workspace’s vtcode.toml.

pub fn invalidate_workspace_cache(workspace: impl AsRef<Path>)

Invalidate the cached configuration for a specific workspace.

Call this when config files may have changed on disk and the next load_from_workspace call should perform a fresh read instead of returning a previously cached result.

pub fn invalidate_all_workspace_cache()

Invalidate every cached workspace configuration.

Used when a session-scoped override changes or is cleared: the cache is keyed by canonical workspace only, so an override-loaded manager for any workspace must not leak into later default loads. This is a rare event (startup and tests), so a full sweep is cheap and safe.

pub fn load_from_workspace(workspace: impl AsRef<Path>) -> Result<Self>

Load configuration from a specific workspace

When the session has an explicit config-file override (captured at startup via session_override::set_explicit_config_path), the override file takes precedence and is loaded as the highest file layer above the default global layers.

pub fn load_from_workspace_with_repository_repair( workspace: impl AsRef<Path>, ) -> Result<Self>

Load a workspace configuration and repair provider settings left by older versions that persisted the merged configuration into a repository-controlled file.

The strict loader still rejects repository-controlled provider definitions and endpoint/credential overrides. This entry point only handles that specific, already-validated violation by removing the prohibited fields from the exact repository layer that introduced it, then retrying the normal load. Explicit session files remain trusted and are never repaired.

pub fn load_from_file(path: impl AsRef<Path>) -> Result<Self>

Load configuration from a specific file

pub fn config(&self) -> &VTCodeConfig

Get the loaded configuration

pub fn phase_timing(&self) -> Option<ConfigPhaseTiming>

Get the timing metrics recorded during loading, if available.

pub fn config_path(&self) -> Option<&Path>

Get the configuration file path (if loaded from file)

pub fn is_repository_controlled_path(&self, path: &Path) -> bool

Return whether a path belongs to a repository-controlled config layer.

This keeps callers that persist a full config document from having to duplicate layer-origin and explicit-session checks.

pub fn workspace_root(&self) -> Option<&Path>

Get the active workspace root for this manager.

pub fn preferred_workspace_config_path(&self, workspace: &Path) -> PathBuf

Resolve the workspace-level config file this manager reads from, i.e. the highest enabled Workspace layer.

With a session-explicit config file (--config / VTCODE_CONFIG_PATH) that layer is the override file itself, so config writes land where the session actually reads from. Falls back to <workspace>/<config_file_name> when no workspace layer is present.

pub fn config_file_name(&self) -> &str

Get the config filename used by this manager (usually vtcode.toml).

pub fn layer_stack(&self) -> &ConfigLayerStack

Get the configuration layer stack

pub fn preferred_user_config_path(&self) -> Option<PathBuf>

Resolve the canonical user-level config file VT Code should write to.

pub fn user_config_paths(&self) -> Vec<PathBuf>

Return every supported user-level config path for the loaded config filename, including paths that do not exist yet.

Callers that monitor configuration must retain the nonexistent paths: a later None -> Some(mtime) transition is a real configuration change.

pub fn watched_config_paths(workspace: &Path) -> Vec<PathBuf>

Return every configuration file location that can affect a workspace.

The list intentionally includes files that do not exist yet. Polling callers can therefore observe file creation as well as modification or deletion. Paths retain their configured spelling so consumers that write a target can still apply the no-follow file policy at the final path component.

pub fn effective_config(&self) -> Value

Get the effective TOML configuration

pub fn has_explicit_top_level_key(&self, key: &str) -> bool

Return whether any enabled layer explicitly sets a top-level key.

Borrow-only scan that avoids a full TOML merge for single-key presence checks on the startup hot path (e.g. default_primary_agent).

pub fn session_duration(&self) -> Duration

Get session duration from agent config

pub fn save_config_to_path( path: impl AsRef<Path>, config: &VTCodeConfig, ) -> Result<()>

Persist configuration to a specific path, preserving comments.

pub fn save_repository_config_to_path( path: impl AsRef<Path>, config: &VTCodeConfig, ) -> Result<()>

Persist configuration to a repository-controlled path.

Repository and project files may contain ordinary settings, but they must never receive trusted provider definitions or provider endpoint and credential overrides from the merged configuration. Existing protected keys are removed as well so this method can repair files written by an older version that flattened the effective configuration.

pub fn sparse_config_value(config: &VTCodeConfig) -> Result<Value>

pub fn current_project_name(workspace_root: &Path) -> Option<String>

Resolve the current project name used for project-level config overlays.

pub fn save_config(&mut self, config: &VTCodeConfig) -> Result<()>

Persist configuration to the manager’s associated path or workspace

Trait Implementations
