## Install
- from [PyPI](https://pypi.org/project/flloat/):
```
pip install flloat
```
- or, from source (`master` branch):
```
pip install git+https://github.com/whitemech/flloat.git
```
- or, clone the repository and install:
```
git clone htts://github.com/whitemech/flloat.git
cd flloat
pip install .
```
## How to use
* Parse a LDLf formula:
```python
from flloat.parser.ldlf import LDLfParser
parser = LDLfParser()
formula_string = "<true*; A & B>tt"
formula = parser(formula_string) # returns a LDLfFormula
print(formula) # prints "<((true)* ; (A & B))>(tt)"
print(formula.find_labels()) # prints {A, B}
```
* Evaluate it over finite traces:
```python
t1 = [
{"A": False, "B": False},
{"A": True, "B": False},
{"A": True, "B": False},
{"A": True, "B": True},
{"A": False, "B": False},
]
formula.truth(t1, 0) # True
```
* Transform it into an automaton (``pythomata.SymbolicAutomaton`` object):
```python
dfa = formula.to_automaton()
assert dfa.accepts(t1)
# print the automaton
graph = dfa.to_graphviz()
graph.render("./my-automaton") # requires Graphviz installed on your system.
```
Notice: `to_dot` requires [Graphviz](https://graphviz.gitlab.io/download/).
For info about how to use a `pythomata.DFA` please look at the [Pythomata docs](https://github.com/whitemech/pythomata).
* The same for a LTLf formula:
```python
from flloat.parser.ltlf import LTLfParser
# parse the formula
parser = LTLfParser()
formula = "F (A & !B)"
parsed_formula = parser(formula)
# evaluate over finite traces
t1 = [
{"A": False, "B": False},
{"A": True, "B": False},
{"A": True, "B": False},
{"A": True, "B": True},
{"A": False, "B": False},
]
assert parsed_formula.truth(t1, 0)
t2 = [
{"A": False, "B": False},
{"A": True, "B": True},
{"A": False, "B": True},
]
assert not parsed_formula.truth(t2, 0)
# from LTLf formula to DFA
dfa = parsed_formula.to_automaton()
assert dfa.accepts(t1)
assert not dfa.accepts(t2)
```
## Features
