Changelog

v3.4.3 (2016-04-07)

  • Fix minor issue in deep path string parsing so that list indexing in paths can be specified as foo[0][1].bar instead of foo.[0].[1].bar. Both formats are now supported.

v3.4.2 (2016-03-24)

  • Fix bug in start_case where capitalized characters after the first character of a word where mistakenly cast to lower case.

v3.4.1 (2015-11-03)

  • Fix Python 3.5, inspect, and pytest compatibility issue with py_ chaining object when doctest run on pydash.__init__.py.

v3.4.0 (2015-09-22)

  • Optimize callback system for performance.
    • Explicitly store arg count on callback for pydash generated callbacks where the arg count is known. This avoids the costly inspect.getargspec call.
    • Eliminate usage of costly guess_builtin_argcount which parsed docstrings, and instead only ever pass a single argument to a builtin callback function.
  • Optimize get/set so that regex parsing is only done when special characters are contained in the path key whereas before, all string paths were parsed.
  • Optimize is_builtin by checking for BuiltinFunctionType instance and then using dict look up table instead of a list look up.
  • Optimize is_match by replacing call to has with a try/except block.
  • Optimize push/append by using a native loop instead of callback mapping.

v3.2.0 (2015-03-03)

  • Make callback invocation have better support for builtin functions and methods. Previously, if one wanted to pass a builtin function or method as a callback, it had to be wrapped in a lambda which limited the number of arguments that would be passed it. For example, _.each([1, 2, 3], array.append) would fail and would need to be converted to _.each([1, 2, 3], lambda item: array.append(item). That is no longer the case as the non-wrapped method is now supported.

  • Make re_replace accept non-string arguments.
  • Make sort_by accept reverse parameter.
  • Make splice work with strings.
  • Make to_string convert None to empty string. (breaking change)
  • Move arrays.join to strings.join. (breaking change)
  • Rename join/implode's second parameter from delimiter to separator. (breaking change)
  • Rename split/explode's second parameter from delimiter to separator. (breaking change)
  • Reorder function arguments for after from (n, func) to (func, n). (breaking change)
  • Reorder function arguments for before from (n, func) to (func, n). (breaking change)
  • Reorder function arguments for times from (n, callback) to (callback, n). (breaking change)
