TaCle: Tabular Constraint Learner
TaCLe is a constraint learner designed for usage in spreadsheets and tabular data.
Installation
pip install tacle
Using TaCLe
Running TaCLe from command line
TaCLe can be used from command line to analyze a CSV file:
python -m tacle data/magic_ice_cream.csv
This returns a list of constraints in the file:
ALLDIFFERENT(T2[:, 1])
ALLDIFFERENT(T1[:, 4])
ALLDIFFERENT(T1[:, 5])
ALLDIFFERENT(T1[:, 6])
T1[:, 1] -> T2[:, 1]
T1[:, 6] = SUM(T1[:, 3:5], row)
Filter output
If you are interested in specific types of constraints, you can filter the output:
python -m tacle data/magic_ice_cream.csv -f "foreign-key" # Report only foreign keys
python -m tacle data/magic_ice_cream.csv -f "<f>" # Report only formulas -- use <c> for only constraints
Tables
To view the tables that TaCLe finds in a file you can run:
python -m tacle data/magic_ice_cream.csv -t
This returns the tables and blocks found by TaCLe:
Table T1, (1:9, 0:7)
Columns 0-2 (string), Columns 2-6 (int), Columns 6-7 (string)
Table T2, (11:15, 0:2)
Columns 0-1 (string), Columns 1-2 (int)
