Struct GenerateContext 

pub struct GenerateContext {
    pub app_meta: AppMeta,
    pub ios: Option<IosProjectIr>,
    pub android: Option<AndroidProjectIr>,
    pub journal: MutationJournal,
    pub app_crate_dir: Option<PathBuf>,
}

The mutable handle plugins receive in Plugin::apply. Wraps every IR the engine is currently materializing plus the running MutationJournal.

Each target IR is Option because not every whisker generate invocation touches both platforms — the CLI passes only the IRs for targets currently enabled by the user’s --target flag. Plugins should if let Some(ios) = &mut ctx.ios { ... } rather than assuming both exist.

Fields

app_meta: AppMeta

Read-only basic facts about the app, derived from Config. Plugins use these as defaults — e.g. an Info.plist plugin sets CFBundleIdentifier from app_meta.ios_bundle_id.

ios: Option<IosProjectIr>

iOS IR. Some when the current whisker generate run is rendering gen/ios/.

android: Option<AndroidProjectIr>

Android IR. Some when the current run is rendering gen/android/.

journal: MutationJournal

Append-only attribution log. The engine inspects this after the pipeline finishes to surface conflicts and verbose summaries; plugins don’t read it directly.

app_crate_dir: Option<PathBuf>

Absolute path to the consuming app crate’s root (the directory holding its Cargo.toml / whisker.rs). Set by the engine before the pipeline runs so plugins can resolve paths the user spelled relative to their app — e.g. whisker-asset’s c.dir("assets") resolves against this.

None in unit tests / pipelines that don’t run from a real app crate. A plugin that needs it should error clearly when it is absent rather than guessing the current working directory — subprocess plugins don’t inherit a reliable cwd.
