Function compile_grammar

pub fn compile_grammar(
    grammar: String,
) -> Result<Grammar, Vec<HashMap<String, String>>>

Compile a grammar string and creates a HashMap with rules found as keys and their components (AST) as entries

In this step, the grammar is validated with the pest reference grammar, and the built-in rules are replaced for their equivalents

use bulk_examples_generator::compile_grammar;

// Grammar string
let mut grammar = r#"
        language = {"Rust" | "Python" | "Go" | "Java" | "PHP" | "Haskell"}
        one = {"1"}
        daysNumber = {one ~ " day" | !one ~ ASCII_NONZERO_DIGIT ~ " days"}
        sentence = {"I have been programming in " ~ language ~ " for " ~ daysNumber ~ "."}
    "#;

// Generate the ast
let grammar_ast = compile_grammar(grammar.to_string());

println!("{:?}", grammar_ast);
