Struct TemplatePreprocessor 

pub struct TemplatePreprocessor { /* private fields */ }

Template rendering preprocessor. Generative (one-way) transform.

Implementations

impl TemplatePreprocessor

pub fn new( extensions: Vec<String>, user_vars: HashMap<String, String>, pather: &dyn Pather, ) -> Result<Self>

Construct a new template preprocessor.

Validates that no user-defined variable uses a reserved name (dodot or env). Populates the MiniJinja environment with the dodot.* builtins from pather + system info, an env.* dynamic lookup, and each user variable as a bare global.

Extensions are normalized at construction: a leading dot (e.g. ".tmpl") is stripped so both "tmpl" and ".tmpl" work.

Trait Implementations

impl Debug for TemplatePreprocessor

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

Formats the value using the given formatter.

impl Preprocessor for TemplatePreprocessor

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.
