0.3.0 - 2022-10-31 💀

BREAKING

• remove the impl Display for generated nodes - goto-bus-stop, pull/330

  The Display impls for generated nodes returned the source text for that
  node. That's not a super common operation but it was very easy to access. It's
  also a very different operation from eg. let content: String = node.string_value().into() which returns the content of a string:
  node.string_value().to_string() returned the string as it was written in the
  source code, quotes and escapes and all.

  Now .to_string() is replaced by a .source_string() method. It allocates a
  new String (just like .to_string() did). A syntax node can represent
  multiple slices (I think to support different structures like Ropes as
  input?), so slicing the original source isn't actually possible.

Fixes

• handle unexpected tokens in top-level document parsing - JrSchild, pull/324
  Unexpected tokens directly inside a document would break the loop in the
  parser, for example:

  @
  {
    name
  }}

  This resulted in the rest of the parsing to be skipped. An error is created
  here instead.

Maintenance

• reduce token copying - goto-bus-stop, pull/323

  • Reduce token copying

  Since the original lexer results are not needed anymore after this step,
  we can take ownership of the tokens and errors vectors and reverse them
  in-place without making a copy. Big schemas can have 100K+ tokens so
  it's actually quite a lot of work to copy them.

  • Reduce double-clones of tokens in the parser

  Some of these clones were not necessary. In particular the .expect
  method cloned the token unconditionally (including the string inside)
  and then cloned the string again immediately afterwards. This removes
  the first clone by reordering the current.index() call to satisfy the
  borrow checker.

  The .data().to_string() clone is only used in the error case, but
  avoiding that will require more work.
