v0.2.0 (2024-10-27)

[mtkennerly]

• Added:
  • Support for the WINE REGISTRY Version 2 format. This includes Wine's global options (e.g., #arch=win32), key-level options (e.g., #link), and string values written as "name"=str:"data".
  • Support for addenda after key names (e.g., [foo] 123). Regedit ignores this, but Wine uses it to store the modified time.
  • error::Deserialize::Unparsable, Registry::format, Format::raw, and KeyName::raw,
• Fixed:
  • Extra backslashes in key paths are now ignored and normalized.
  • Quotes and semicolons in key names no longer corrupt the deserialization.
  • Empty string values are now preserved when deserializing.
  • Parsing performance would degrade as the size of the input increased. On each key/value insert, the library would iterate through all keys/values found so far to check for a potential case-insensitive match. Now, the library caches the case-normalized form on insert, so that later lookups are O(1).
• Changed:
  • Parsing is now much faster due to moving away from regular expressions. In release mode, the library can parse a 520 MB full registry export in 5 seconds, which would have taken 20 seconds previously (even with the key lookup fix mentioned above).
  • Key is now a struct instead of an enum.
  • Values serialized as hexadecimal bytes (e.g., Kind::Binary) are now split onto multiple lines when they're long enough.
  • Renamed Registry::update to Registry::insert, Key::update to Key::insert, and added underscores to the Format string constants.
• Removed:
  • Registry::keys_mut because it would interfere with the case-normalized lookup optimizations.
  • Dependency on once_cell, using std::sync::LazyLock instead.
