The trait that describes the specific implementation of a given language.

TODO: move language-specific integrations into own crate. Options would have to be transferred to a local type.

Required Methods

fn copy(&self) -> Box<Lang>

Copy self.

Implemented through lang_base! macro.

fn module_specs(
    &self,
    path: &Path,
    input: Option<Value>
) -> Result<Vec<Box<Any>>>

Parse a complex set of module configurations.

Implemented through lang_base! macro.

fn string_spec(&self, path: &Path, input: &str) -> Result<Box<Any>>

Parse a module configuration consisting of only a string.

Implemented through lang_base! macro.

fn compile(
    &self,
    ctx: Rc<Context>,
    env: Environment,
    manifest: Manifest
) -> Result<()>

Language-specific compile hook.

Implemented through lang_base! macro.

Provided Methods

fn comment(&self, _input: &str) -> Option<String>

Comment the given string.

fn keywords(&self) -> Vec<(&'static str, &'static str)>

Get a list of keywords to transliterate.

fn safe_packages(&self) -> bool

Indicates if the language requires keyword-escaping in the packages.

fn into_env(
    &self,
    ctx: Rc<Context>,
    package_prefix: Option<RpPackage>,
    resolver: Box<Resolver>
) -> Environment

Helper to convert into environment.

fn package_naming(&self) -> Option<Box<Naming>>

Rename packages according to the given naming convention.
