It will also sort your rules topologically, so that rules that depend on other rules are defined after the rules they depend on. This is useful for the parser generator, which will generate a parser that is more efficient if the rules are defined in this order. AboutSort of a real-world example of a modern VS Code extension using the newly formulated LSP (Language Server Protocol) and the new VS Code API. That notwithstanding, this is still fairly useful for anyone looking to write a grammar using a BNF-like syntax. Created because I was tired of writing grammar files with the fairly cumbersome EBNF syntax. And moreover had no way of validating, formatting, or otherwise working with my grammar files. VS code's got me spoiled 😭. |
