gdscript tools for abstract manipulation of ASTs.

ALL TOOLS ARE UNSTABLE. The grammer is subject to change at any time, and so are formatting tools, as of 0.x

• GDScript parser (first!)
• GDScript linter (analyze the AST to find common patterns of mistakes)
• GDScript formatter (parse and restringify the AST)
• GDScript LSP integration (provide additional information to linters to provide extra hints)

We use pest for making grammar. As a good reference guide, GDScript has a EBNF grammar.

However, since it is EBNF and not PEG, and doesn't really comform to the implementation, there may be some extra edge cases that are covered in test.
