This section contains code examples for using Spot.  This is a work in
progress.  Feel free to [[mailto:spot@lrde.epita.fr][send]] suggestions of small tasks you would like
to see illustrated here.

If you have difficulties compiling the C++ examples, check out [[file:compile.org][these
instructions]].

* Examples with Shell, Python, and C++

All the following pages show how to perform the same task using the
three interfaces supported by Spot: shell commands, Python, or C++.

- [[file:tut01.org][Parsing and Printing LTL Formulas]]
- [[file:tut02.org][Relabeling Formulas]]
- [[file:tut10.org][Translating an LTL formula into a never claim]]
- [[file:tut20.org][Converting a never claim into HOA]]
- [[file:tut30.org][Converting Rabin (or Other) to Büchi, and simplifying it]]

* Examples in Python and C++

- [[file:tut03.org][Constructing and transforming formulas]]
- [[file:tut21.org][Custom print of an automaton]]
- [[file:tut22.org][Creating an automaton by adding states and transitions]]

* Examples in Python only

In directory =python/tests=, the [[file:install.org][Spot tarball]] contains a small
collection of IPython notebooks.  As the name of the directory implies,
these are part of the test suite for the Python bindings, however they
can be interesting to look at if you want to see more code examples.

For convenience, the following links offer static HTML renderings of
these notebooks, but we strongly suggest interactively evaluating the
real notebooks instead.

- [[https://spot.lrde.epita.fr/ipynb/formulas.html][=formulas.ipynb=]] covers the basics of LTL/PSL formula parsing and
  printing, with some light operations
- [[https://spot.lrde.epita.fr/ipynb/automata.html][=automata.ipynb=]] covers translation from formulas to automata,
  automata printing, and some lights transformations
- [[https://spot.lrde.epita.fr/ipynb/automata-io.html][=automata-io.ipynb=]] shows how to save and read automata from files
- [[https://spot.lrde.epita.fr/ipynb/piperead.html][=piperead.ipynb=]] shows how to save and read automata output from other
  commands, using pipes
- [[https://spot.lrde.epita.fr/ipynb/randaut.html][=randaut.ipynb=]] shows a simple case where the [[file:randaut.org][=randaut=]] commands
  generated random automata, which are displayed in a table before and
  after acceptance simplification
- [[https://spot.lrde.epita.fr/ipynb/accparse.html][=accparse.ipynb=]] exercises the acceptance condition parser
- [[https://spot.lrde.epita.fr/ipynb/acc_cond.html][=acc_cond.ipynb=]] documents the interface for manipulating acceptance
  conditions
- [[https://spot.lrde.epita.fr/ipynb/product.html][=product.ipynb=]] shows how to re-implement the product of two automata
  in Python
- [[https://spot.lrde.epita.fr/ipynb/randltl.html][=randltl.ipynb=]] demonstrates a Python-version of [[file:randltl.org][=randltl=]]
- [[https://spot.lrde.epita.fr/ipynb/decompose.html][=decompose.ipynb=]] illustrates the =decompose_strength()= function
- [[https://spot.lrde.epita.fr/ipynb/testingaut.html][=testingaut.ipynb=]] shows the step necessary to build a testing
  automaton
