            Bug ID: 148754
           Summary: Migrate from flex/bison -> boost::spirit or similar
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2

The Flex and Bison parser generators are becoming an every increasing maintenance burden:

1. More recent versions of this software have undesirable GPL v3 licensing.
2. Different platforms have access to different versions of the software (e.g., Mac is limited to Bison 2.3)
3. Flex and Bison are difficult to obtain and use on Windows.

Instead, it would be nice to move towards a more modern parser generator approach, possibly using something like Boost::spirit.
