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

* 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]]

* Examples in C++ only

The following examples are too low-level to be implemented in shell or
Python (at least at the moment), so they are purely C++ so far.

- [[file:tut21.org][Custom print of an automaton]]
- [[file:tut22.org][Creating an automaton in C++]]

* Examples in Python only

In directory =wrap/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/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
