AUTDO

autdo - run automata through other tools

autdo [OPTION...] [COMMANDFMT...]

Run automata through other programs, performing conversion of input and output as required.

Input:

-F, --file=FILENAME

process automata from FILENAME

Specifying tools to call:

--list-shorthands

list availabled shorthands to use in COMMANDFMT

-t, --tool=COMMANDFMT

register one tool to call

-T, --timeout=NUMBER

kill tools after NUMBER seconds

COMMANDFMT should specify input and output arguments using the following character sequences:

%H,%S,%L

filename for the input automaton in (H) HOA, (S) Spin’s neverclaim, or (L) LBTT’s format

%M, %[val]M

the name of the input automaton, with an optional default value

Parsing of automata:

--trust-hoa=BOOL

If false, properties listed in HOA files are ignored, unless they can be easily verified. If true (the default) any supported property is trusted.

Error handling:

--errors=abort|warn|ignore

how to deal with tools returning with non-zero exit codes or automata that autdo cannot parse (default: abort)

--fail-on-timeout

consider timeouts as errors

Output selection:

--greatest[=FORMAT]

for each automaton select the greatest output automaton given by all tools, using FORMAT for ordering (default is %s,%e)

-n, --max-count=NUM

output at most NUM automata

--smallest[=FORMAT]

for each automaton select the smallest output automaton given by all tools, using FORMAT for ordering (default is %s,%e)

Output format:

-8, --utf8

enable UTF-8 characters in output (ignored with --lbtt or --spin)

--check[=PROP]

test for the additional property PROP and output the result in the HOA format (implies -H). PROP may be some prefix of ’all’ (default), ’unambiguous’, ’stutter-invariant’, ’stutter-sensitive-example’, ’semi-determinism’, or ’strength’.

-d, --dot[=1|a|A|b|B|c|C(COLOR)|e|E|f(FONT)|h|i(ID)|k|K|n|N|o|r|R|s|t|u|v|
y|+INT|<INT|#]

GraphViz’s format. Add letters for (1) force numbered states, (a) show acceptance condition (default), (A) hide acceptance condition, (b) acceptance sets as bullets, (B) bullets except for Büchi/co-Büchi automata, (c) force circular nodes, (C) color nodes with COLOR, (d) show origins when known, (e) force elliptic nodes, (E) force rEctangular nodes, (f(FONT)) use FONT, (g) hide edge labels, (h) horizontal layout, (i) or (i(GRAPHID)) add IDs, (k) use state labels when possible, (K) use transition labels (default), (n) show name, (N) hide name, (o) ordered transitions, (r) rainbow colors for acceptance sets, (R) color acceptance sets by Inf/Fin, (s) with SCCs, (t) force transition-based acceptance, (u) hide true states, (v) vertical layout, (y) split universal edges by color, (+INT) add INT to all set numbers, (<INT) display at most INT states, (#) show internal edge numbers

-H, --hoaf[=1.1|b|i|k|l|m|s|t|v]

Output the automaton in HOA format (default). Add letters to select (1.1) version 1.1 of the format, (b) create an alias basis if >=2 AP are used, (i) use implicit labels for complete deterministic automata, (s) prefer state-based acceptance when possible [default], (t) force transition-based acceptance, (m) mix state and transition-based acceptance, (k) use state labels when possible, (l) single-line output, (v) verbose properties

--lbtt[=t]

LBTT’s format (add =t to force transition-based acceptance even on Büchi automata)

--name=FORMAT

set the name of the output automaton

-o, --output=FORMAT

send output to a file named FORMAT instead of standard output. The first automaton sent to a file truncates it unless FORMAT starts with ’>>’.

-q, --quiet

suppress all normal output

-s, --spin[=6|c]

Spin neverclaim (implies --ba). Add letters to select (6) Spin’s 6.2.4 style, (c) comments on states

--stats=FORMAT, --format=FORMAT

output statistics about the automaton

Any FORMAT string may use the following interpreted sequences:

%c, %[LETTERS]c

number of SCCs; you may filter the SCCs to count using the following LETTERS, possibly concatenated: (a) accepting, (r) rejecting, (c) complete, (v) trivial, (t) terminal, (w) weak, (iw) inherently weak. Use uppercase letters to negate them.

%e, %[LETTER]e

number of edges (add one LETTER to select (r) reachable [default], (u) unreachable, (a) all).

%g, %[LETTERS]g

acceptance condition (in HOA syntax); add brackets to print an acceptance name instead and LETTERS to tweak the format: (0) no parameters, (a) accentuated, (b) abbreviated, (d) style used in dot output, (g) no generalized parameter, (l) recognize Street-like and Rabin-like, (m) no main parameter, (p) no parity parameter, (o) name unknown acceptance as ’other’, (s) shorthand for ’lo0’.

%R, %[LETTERS]R

CPU time (excluding parsing), in seconds; add LETTERS to restrict to (u) user time, (s) system time, (p) parent process, or (c) children processes.

%s, %[LETTER]s

number of states (add one LETTER to select (r) reachable [default], (u) unreachable, (a) all).

%t, %[LETTER]t

number of transitions (add one LETTER to select (r) reachable [default], (u) unreachable, (a) all).

%u, %[e]u

number of states (or [e]dges) with universal branching

%u, %[LETTER]u

1 if the automaton contains some universal branching (or a number of [s]tates or [e]dges with universal branching)

%x, %[LETTERS]x

number of atomic propositions declared in the automaton; add LETTERS to list atomic propositions with (n) no quoting, (s) occasional double-quotes with C-style escape, (d) double-quotes with C-style escape, (c) double-quotes with CSV-style escape, (p) between parentheses, any extra non-alphanumeric character will be used to separate propositions
