brabbel 0.4.3

A simple python based expression language

Brabbel

Brabbel is a small python based expression language which can be used to evaluate simple expressions.

Brabbel provides the following set of features:

• Values: Strings, Numbers, Variables , Lists

• simple arithmetic operations: + - / *

• simple equation : < > <= >= == !=

• simple bool operation: and or not

• function calls: date, bool

• other: check if values is _in_ a list

Brabbel is the german term for the first “language” of a baby and emphasises the reduced coverage of this language. 0.5.0 =====

0.4.3

• Improved parsing single quoted strings. Now almost all chars are allowed except a single quote “’” will will raise an execption because parsing fails. Because the fix is a improvement at all and the remaining bug is is currently considered as a rare corner case. This will be released anyway.

0.4.2

• Added workaround for failing parsing of expressions when pyparsing is under high load.

0.4.1

• Changed license from MIT to GPL v2+ and added LICENSE.txt

• Added “bdist_rpm” section setup.cfg.

• Added “egg_info” section setup.cfg.

0.4.0

• Make comparison of operators more type safe. Evaluation of terms is only valid of operators of the same type. Otherwise the term will evaluate to False.

• Implement short circuiting for “and” and “or” operators.

• Support “True”,”False”,”None” in bool function.

• Refactored code. Created own module for operators and functions.

• Added documentation.

0.3.0

Make Brabbel Python3 compatible. Added python-future package as dependency

• Allow dots “.” in variable names.

0.2.7

• Fixed handling of integer and string values in lists.

0.2.6

• Added folders for documentation (currently empty)

• Allow “-” in Strings

• Added more tests.

0.2.5

• Log warning if a variable can not be resolved in the values dict.

• Allow signed numbers. Currently only negativ sign is allowed.

• String to not have a “’” anymore.

• Added more tests.

0.2.4

• Compatiblity: Allow “-” in variable names.

• Fixed strip of “’” in “len” function.

0.2.3

• Allow empty strings

• Fix bool function

• Allow lists as param for functions

0.2.2

• Added len function

0.2.1

• Be more tolerant on whitespaces in delimeted lists,

• Fix call of functions

0.2

• Add operator mapping for operators like ge, gt, le, lt, eq, ne

• Be more tolerant on getting non existing values from the values dictionary.

• Removed Rule class.
