First and foremost, thank you for stepping in and trying to be part of the effort.

Goals

When expanding Kint, keep in mind its main priorities:

  1. Commit built resources: Developers must be able to install Kint effortlessly and start using it immediately with no additional required steps. JS/CSS resources and the phar file should be rebuilt with composer build and committed when changed.
  2. No feature creep: Requests for edge use cases, especially ones that can be worked around with some configuration, should not be catered to. With few exceptions only core PHP functionality should be supported.
  3. Do not compromise information clarity: Displaying relevant information is the entire purpose of Kint. Try to ensure your output is as clear and correct as possible.
  4. Code quality: the nature of Kint implies that it will be continued to develop for many years - at least to adapt to new language features and quirks. Keep the codebase as maintainable as possible. Keep code style and quality consistent by finishing every commit with composer format, and composer analyze.
  5. Stable releases: Try not to push backwards compatibility breaking or untested changes to the master branch outside of a major version upgrade where a branch exists for the previous version
  6. Don't alter user input: For the parser to do proper recursion checking it has to take things by reference. Since it's taking things by reference there's a good chance your parser plugin can change your end-users data. NEVER ALTER INPUT VARIABLES
