AST

[Andreas Franzén]

Hello, is it possible to parse a string and just get the ast without having had it transformed so one can change it and then send it to the transformer?

That's a great idea -- unless you want to give it a go, I'll play with implementing it next week.

Hey @triptec -- there's currently a slightly convoluted way for you to accomplish what you want:

For some My.Grammar using Neotomex.ExGrammar and a custom transform function my_transform you might do:

parsed = My.Grammar.grammar
  |> Neotomex.Grammar.match("string to parse")
  |> my_transform
  |> Neotomex.Grammar.transform_match

Moving forward, we could wrap the match function for the ExGrammar allowing something like the following -- what do you think?

parsed = "string to parse"
  |> My.Grammar.match
  |> my_transform
  |> Neotomex.Grammar.transform_match

Ok, I'll have to look in to this next week. Thanks for taking the time

I'm going to mark this as closed since I have no current plans to implement and their are instructions for hacking around it above.
