Proc_macro parse function between brackets

tonis · July 21, 2020, 3:33pm

I am writing a little JSX-like parser with syn and proc_macro2.

Parsing the Nodes and Attributes is working fine, but i don't understand how to implement the inline functions.

For example, i compile the array between brackets and can forward the quote! tokens into my parser.

parse_node(
       quote!(<element>
         {
          (0..3).map(|| quote!(<text value="new"></text>))
         } 
       </element>
      ) 
 )

Currently i get the map function as tokens too, but is it possible to convert it into rust code immediately without parsing?

    fork.parse::<Token![>]>()?;

    if self.tag != tag.to_string() {
        return Err(Error::new(tag.span(), "Tag ends with wrong name!"));
    }

    input.advance_to(&fork);
    Ok(())
}

//How to implement this code block parsin ??
fn get_block(&self, input: ParseStream) -> Result<()> {
    let fork = input.fork();
    // let parser = move |input: ParseStream| input.parse();
    let group: Group = fork.parse()?;

    
    input.advance_to(&fork);
  

    // let expr: Box<Expr> = syn::parse2(group.stream())?;
