26 /// @brief Construct an abstract syntax tree from a code snippet.
27 /// @details This method parses the provided null terminated code snippet and
28 /// attempts to construct a complete abstract syntax tree (AST) which can be
29 /// passed to the AX Compiler. If the code is not well formed (as defined by
30 /// the AX grammar) a nullptr is returned and instances of any errors
31 /// encoutered are stored to the provided logger.
32 /// @note The returned AST is const as the logger uses this to determine line
33 /// and column numbers of errors/warnings in later stages. If you need to
34 /// modify the tree, take a copy.
35 ///
36 /// @return A shared pointer to a valid const AST. Can be a nullptr on error.
37 /// @todo In the future it may be useful for ::parse to return as much of
38 /// the valid AST that exists.
39 ///
40 /// @param code The code to parse
41 /// @param logger The logger to collect syntax errors
