Struct ThemeRegistry 

pub struct ThemeRegistry { /* private fields */ }

A registry of discovered custom theme files: display name → path.

Built once per TUI session by scanning the resource theme dirs; names are file stems, first-wins on conflict (project .rpi/themes overrides the global ~/.rpi/agent/themes). Parsing is lazy: the registry only lists files, and a theme is parsed when selected or applied, so a broken JSON file cannot break the other themes.

Implementations

impl ThemeRegistry

pub fn merge_discovered(&mut self, paths: &[String])

Merge bare extension-contributed theme file paths (resources_discover themePaths) into this registry.

Priority sits after the static dirs: a static dir theme of the same stem wins, extension themes fill the remaining names. This matches the skill/prompt precedence (static first-wins, discovered lower). Paths are concrete .json files (the pi contract, unlike skills’ dir-or-file); names are file stems. v1 divergence (documented upstream parity gap): paths are unattributed, so diagnostics can only name the path.

pub fn discover(cwd: &Path, project_trusted: bool) -> (Self, Vec<String>)

Scan the global + project theme dirs. Project themes win on name conflicts. project_trusted == false skips the project dir entirely (the same trust boundary as skills: an untrusted repo must not shape the UI on first open).

Returns the registry plus soft diagnostics for unreadable dirs.

pub fn discover_from( global: Option<&Path>, project: Option<&Path>, ) -> (Self, Vec<String>)

Scan explicit dirs (test seam; discover resolves the standard dirs).

pub fn get(&self, name: &str) -> Option<&PathBuf>

Look up a discovered theme by name (file stem, case-sensitive).

pub fn names(&self) -> impl Iterator<Item = &String>

Discovered names in display order (alphabetical).

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize
