Struct AgePreprocessor 

pub struct AgePreprocessor { /* private fields */ }

age decryption preprocessor. Constructed from [preprocessor.age] config + the shared CommandRunner.

Holds the identity path resolved at construction so every expand() call uses the same identity file (no re-reading of env vars per file). The path is not validated to exist at construction; age validates at decrypt time and emits a diagnostic we surface verbatim if the file is missing.

Implementations

impl AgePreprocessor

pub fn new( runner: Arc<dyn CommandRunner>, identity: PathBuf, extensions: Vec<String>, ) -> Self

pub fn from_env(runner: Arc<dyn CommandRunner>) -> Self

Construct with the canonical ~/.config/age/identity.txt default identity and the default ["age"] extension set — matches what most users have installed via age-keygen.

Trait Implementations

impl Preprocessor for AgePreprocessor

fn name(&self) -> &str

Unique name for this preprocessor (e.g. "template", "plist").

fn transform_type(&self) -> TransformType

The safety model for this transformation.

fn matches_extension(&self, filename: &str) -> bool

Whether this preprocessor handles a file with the given name.

fn stripped_name(&self, filename: &str) -> String

Strip the preprocessor extension to get the logical filename. e.g. "config.toml.tmpl" → "config.toml".

fn expand(&self, source: &Path, _fs: &dyn Fs) -> Result<Vec<ExpandedFile>>

Expand the source file into one or more output files.

fn supports_reverse_merge(&self) -> bool

Whether this preprocessor participates in the reverse-merge pipeline. Reverse-merge is the cache-backed flow that lets dodot transform check propagate edits from the deployed file back into the source by writing a unified diff (and, for ambiguous edits, dodot-conflict marker blocks).
