New in spot 2.0a (not yet released)
|
||||
|
||||
Library:
|
||||
|
||||
* The print_hoa() function will now output version 1.1 of the HOA
|
||||
format when passed the "1.1" option (i.e., use -H1.1 from any
|
||||
command-line tool). As far as Spot is concerned, this allows
|
||||
negated properties to be expressed. Version 1 of the HOA format
|
||||
is still the default, but we plan to default to version 1.1 in the
|
||||
future.
|
||||
|
||||
Bug fixes:
|
||||
|
||||
* Typo in documentation of the -H option in --help output.

Spot can read files written using either version 1 or version 1.1 of

the HOA format. It currently outputs version 1 by default, but

version 1.1 can be requested from the command-line using option

=-H1.1=. Future version of Spot are likely to switch to version 1.1

of HOA by default, so version 1 can already be requested explicitly

The above table is for version 1 of the format. When version 1.1 is

selected (using =-H1.1=), some negated properties may be output. In

particular, =stutter-sensitive= is replaced by =!stutter-invariant=.

The logic of not cluttering the output with all of =!terminal=,

=!weak=, and =!inhenrently-weak= is similar to the positive versions:

=!inherently-weak= implies =!weak= which in turn implies =!terminal=,

Finally, version 1.1 of the HOA format can be specified using the
|
||||
=-H1.1= option. Version 1, which is currently the default, can also
|
||||
be requested explicitly using =-H1=. The main advantage of version
|
||||
1.1, as far as Spot is concerned, is that some of negated properties
|

can be transmitted. For instance, compare

The =--check= option inspects the automata for additional properties
|
||||
such that their strength or whether they are stutter-invariant and

unambiguous. You can see in this example that version 1.1 of the
|
||||
format carries additional negated properties that could not be

represented in the first version.
