Changelog

2.2.3 - fixed packaging

• packaging improvements: set the "universal wheel" flag to 1, and cleaned up the setup.py. In particular removed dependency to six for setup. Fixes #21

2.2.2 - Minor packaging improvements

• Added __version__ attribute. Fixes #20
• Improved setup.py, in particular long description now uses markdown (no pandoc anymore) and zip_safe is false. Fixes #18
• Added py.typed file for PEP561 compliance. Fixes #19

2.2.1 - pyproject.toml

Added pyproject.toml.

2.2.0 - Better signature for mini-lambda functions

When converting an expression into a function, the resulting callable object now has the same signature than inner evaluate. Fixes #17.

2.1.0 - New features to improve usability.

• Added two helper functions is_mini_lambda_expr and as_function. Fixes #13

• Renamed _LambdaExpression to LambdaExpression. It is now exported at package lavel, that's clearer.

• Added __repr__ to LambdaFunction. Fixes #14.

2.0.1 - fixed dependency issue

• in 2.0.0 pandas and numpy were mandatory again. Fixed that.

2.0.0 - python 2 support, default repr, and cleaner submodules structure

• Lambda expressions now have a normal repr by default, and this can be disabled by using the repr_on attribute to False. Fixes #12

• Added support for python 2. Fixes #11.

• The package structure is now cleaner. In particular, predefined variables are in mini_lambda.vars and predefined symbols (constants, functions and classes) are in mini_lambda.symbols.

1.4.0 - fixed initial import time + added And() and Or()

• Fixed #5 by making numpy and pandas import optional: they are now only imported if you import mini_lambda.numpy_ or mini_lambda.pandas_ respectively.

• New And() and Or() functions, see #7

1.3.1 - fixed ImportError in code generation

• the latest autoclass has its __init__.py fixed, this revealed a ImportError: cannot import name 'getmembers' because we were importing getmembers from it instead of inspect. Fixed

1.3.0 - fixed init.py

• The init file has been improved so as not to export symbols from other packages. Fixes #6

1.2.4 - Minor improvements in generated goodies

• Removed annoying warning message when loading goodies
• Removed useless try/except for goodies that do not need import

1.2.3 - Fixed minor bug in code generation

• Removed all None that were appearing in the goodies_generated.py file
• Now compliant with old versions of typing module: typing.Type is not imported explicitly anymore.

1.2.2 - Fixed code generation to solve two import errors

• Fixed #3 and #4. Generated source code has been removed from version control to avoid this kind of errors in the future.
• Travis script has been equipped with an automatic module import checker to detect such issues earlier next time.

1.2.0 - New alias and bugfix for constant functions

• added alias make_lambda_friendly for Constant, since it is able to convert anything (constants, functions and classes) to lambda-friendly objects usable in expressions.
• Fixed #2 that was a bug happening when using lambda-friendly methods with non-lambda arguments

1.1.0 - Compatibility with standard functions

• It is now possible to use any function in a lambda expression, through use of the make_lambda_friendly_... methods (see documentation)
• All built-in methods as well as all constants, methods and classes from the math.py and decimal.py modules are provided in a lambda-friendly way by the package for convenience
• Updated documentation accordingly, and made main page clearer
• Renamed class _InputEvaluator into _LambdaExpression
• A few bugfixes in particular support for keyword arguments when a function call is made in a lambda expression
• <expr>.nnot(), <expr>.any() and <expr>.all() renamed <expr>.not_(), <expr>.any_() and <expr>.all_() for consistency and to avoid conflicts with any()/all() methods that would already be defined in the class, for example NumPy.

1.0.0 - First public version

• Initial fork from valid8 sources.
• Added documentation and printability of expressions, which implied to properly handle operator precedence.
