Changelog

All notable changes between releases will be documented in this file.

The format is based on Keep a Changelog.

Unreleased

  • removes the types module and replaces it with ast

  • the ast modules has better types and sum types

  • removes ParsedType in favor of Expr

  • removes the value module. methods on Value go on the individual types. For example, string related methods go on ast::Str

  • parse changed to Root::parse

  • NODE_OR_DEFAULT is removed

  • NODE_KEY -> NODE_ATTRPATH, NODE_KEY_VALUE -> NODE_ATTRPATH_VALUE

  • BinOp::IsSet is removed since it's actually not a normal binary operator.

  • NODE_SELECT is flattened in favor of NODE_ATTRPATH which consists of multiple Attrs, including a.b.c and a.b.c or expr

  • a or b is Apply, not "OrDefault", which matches the result of Nix. Fixes #23

  • ${ is considered invalid at Expr places now, which matches the result of Nix.

  • remove TOKEN_DYNAMIC_START and TOKEN_DYNAMIC_END

  • rowan 15.0

  • various other parsing fixes

v0.10.2 - 2022-06-14

  • Correctly parse every possible case of path-interpolation in Nix code (#85).

    (from @ncfavier).

v0.10.1 - 2021-12-06

Fixed

  • Trivia tokens (i.e. , \r, \n etc.) are no longer misplaced around path-expressions. This is a regression from v0.10.0 which would've broken nixpkgs-fmt.

    (from @Ma27).

v0.10.0 - 2021-11-30

Added

  • Support for the new path-interpolation syntax from Nix 2.4 was added. The parser now correctly detects

    ./foo/${bar}

    as valid code and parses it down to

    NODE_ROOT 0..13 {
  NODE_PATH_WITH_INTERPOL 0..12 {
    TOKEN_PATH("./foo/") 0..6
    NODE_STRING_INTERPOL 6..12 {
      TOKEN_INTERPOL_START("${") 6..8
      NODE_IDENT 8..11 {
        TOKEN_IDENT("bar") 8..11
      }
      TOKEN_INTERPOL_END("}") 11..12
    }
  }
  TOKEN_WHITESPACE("\n") 12..13
}

    Paths without interpolation are still within NODE_LITERAL for backwards-compatibility.

    (from @Ma27).

  • rnix::types::ParsedTypeError now implements the Debug, Copy, Clone, fmt::Display traits (from @NerdyPepper).

  • During development, the parser can be tested like this:

    $ cargo run --example from-stdin <<< 'builtins.map (x: x * x) [ 1 2 3 ]'

    (from @efx).

Changed

  • A few more examples of invalid inherit-expressions are correctly marked as such (from @oberblastmeister).

  • rnix::types::BinOp::operator() now returns Option<BinOpKind> rather than unwrapping the value (from @NerdyPepper).

    If your code worked fine before, it will be sufficient to add a .unwrap() since this was what happened before within ::operator().

  • Duplicated arguments in the argument-pattern syntax are now marked as parser error. E.g.

    { a, a }: a

    now produces an error (from @Ma27).

  • Floats without trailing zeroes (e.g. .5) are no longer marked as syntax error (from @Ma27).

v0.9.1 - 2021-09-23

Changed

  • Fixed a memory leak while parsing inherit-expressions with invalid syntax (from @Ma27).
