#+TITLE: =genltl=
#+DESCRIPTION: Spot command-line tool that generates LTL formulas from known patterns
#+SETUPFILE: setup.org
#+HTML_LINK_UP: tools.html
This tool outputs LTL formulas that either comes from named lists of
formulas, or from scalable patterns.
These patterns are usually taken from the literature (see the
[[./man/genltl.1.html][=genltl=]](1) man page for references). Sometimes the same pattern is
given different names in different papers, so we alias different
option names to the same pattern.

An example is probably all it takes to understand how this tool works:

genltl --and-gf=1..5 --u-left=1..5
#+END_SRC
#+RESULTS:
#+begin_example

#+end_example
=genltl= supports the [[file:ioltl.org][common option for output of LTL formulas]], so you
may output these pattern for various tools.
For instance here is the same formulas, but formatted in a way that is
suitable for being included in a LaTeX table.
#+BEGIN_SRC sh :results verbatim :exports both
genltl --and-gf=1..5 --u-left=1..5 --latex --format='%F & %L & $%f$ \\'
#+END_SRC
#+RESULTS:
#+begin_example

u-left & 2 & $p_{1} \U p_{2}$ \\
u-left & 3 & $(p_{1} \U p_{2}) \U p_{3}$ \\
u-left & 4 & $((p_{1} \U p_{2}) \U p_{3}) \U p_{4}$ \\
u-left & 5 & $(((p_{1} \U p_{2}) \U p_{3}) \U p_{4}) \U p_{5}$ \\
#+end_example
Note that for the =--lbt= syntax, each formula is relabeled using
=p0=, =p1=, ... before it is output, when the pattern (like
=--ccj-alpha=) use different names. Compare:
#+BEGIN_SRC sh :results verbatim :exports both
genltl --ccj-alpha=3
#+END_SRC
#+RESULTS:
: F(F(Fq3 & q2) & q1) & F(F(Fp3 & p2) & p1)
with
#+BEGIN_SRC sh :results verbatim :exports both
genltl --ccj-alpha=3 --lbt
#+END_SRC
#+RESULTS:
: & F & p2 F & p1 F p0 F & F & F p3 p4 p5
This is because most tools using =lbt='s syntax require atomic
propositions to have the form =pNN=.
Three options provide lists of unrelated LTL formulas, taken from the
literature (see the [[./man/genltl.1.html][=genltl=]](1) man page for references):
=--dac-patterns=, =--eh-patterns=, and =--sb-patterns=. With these
options, the range is used to select a subset of the list of formulas.
Without range, all formulas are used. Here is the complete list:
#+BEGIN_SRC sh :results verbatim :exports both

Note that ~--sb-patterns=2 --sb-patterns=4 --sb-patterns=21..22~ also
have their complement formula listed as ~--sb-patterns=3
--sb-patterns=8 --sb-patterns=23..24~. So if you build the set of
formula output by =genltl --sb-patterns= plus its negation, it will
contain only 46 formulas, not 54.
