Trait Implementations

impl Clone for Java

fn clone(&self) -> Java

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Language for Java

fn get_ts_language(&self) -> TSLanguage

tree sitter language to parse the source

fn from_path<P>(_path: P) -> Option<Self>

where P: AsRef<Path>,

Return the file language from path. Return None if the file type is not supported.

fn ast_grep<S>(&self, source: S) -> AstGrep<StrDoc<Self>>

where S: AsRef<str>,

Create an AstGrep instance for the language

fn skippable_kind_ids(&self) -> &'static [u16]

ignore trivial tokens in language matching

fn pre_process_pattern<'q>(&self, query: &'q str) -> Cow<'q, str>

normalize pattern code before matching e.g. remove expression_statement, or prefer parsing {} to object over block

fn meta_var_char(&self) -> char

Configure meta variable special character By default $ is the metavar char, but in PHP it can be #

fn expando_char(&self) -> char

Some language does not accept $ as the leading char for identifiers. We need to change $ to other char at run-time to make parser happy, thus the name expando. By default this is the same as meta_var char so replacement is done at runtime.

fn extract_meta_var(&self, source: &str) -> Option<MetaVariable>

extract MetaVariable from a given source string At runtime we need to use expand_char
