Instance Method Details

#find_sexps(type, tree = self.parse(self.body)) ⇒ Array<Sexp>

Finds all sexps of the given type in the given Sexp tree.

Parameters:

  • type (Symbol) —

    the type of sexp to search for

  • tree (Sexp) (defaults to: self.parse(self.body)) —

    (self.parse(self.body)) The tree to search in. Leave blank to search the entire body.

Returns:

  • (Array<Sexp>) —

    all sexps in the input tree (or whole body) that are of the given type.

  tree.each do |node|
    result.concat find_sexps(type, node) if node.is_a?(Array)
  end
  result
end

#parse(body = self.body) ⇒ Sexp, NilClass

Parses the given text.

Parameters:

  • body (String) (defaults to: self.body) —
