A DPS Simulator 2 - SimFF

Whee, the grammar works.

I opted for grammar simplicity and to do more of the semantic work in the backend, instead of trying to parse specific keywords.

As far as I can tell the grammar is correct. Next step is the semantic parsing and attaching actions to nonterminals.

Here is the full grammar:

actionb  (Nullable) 
   actionb -> , string actionb 
   actionb -> 
actions  (Nullable) 
   actions -> string actionb 
   actions -> 
actionStatement
   actionStatement -> ( conditionals ) { actions } 
   actionStatement -> comment 
actionStatement+
   actionStatement+ -> actionStatement+ actionStatement 
   actionStatement+ -> actionStatement 
actionStatements  (Nullable) 
   actionStatements -> 
   actionStatements -> actionStatement+ 
actorAdd
   actorAdd -> actorList += string 
actorList
   actorList -> *players 
   actorList -> *targets 
boolVar
   boolVar -> string boolVarb 
boolVarb  (Nullable) 
   boolVarb -> . string boolVarb 
   boolVarb -> 
conditional
   conditional -> boolVar test number 
   conditional -> ! boolVar 
   conditional -> boolVar 
conditionalb  (Nullable) 
   conditionalb -> & conditional conditionalb 
   conditionalb -> 
conditionals  (Nullable) 
   conditionals -> conditional conditionalb 
   conditionals -> 
gcd
   gcd -> [GCD] actionStatements 
ogcd
   ogcd -> [OGCD] actionStatements 
precast
   precast -> [PRECAST] actionStatements 
script
   script -> setup precast gcd ogcd 
script'
   script' -> script EOF 
setup
   setup -> [SETUP] setupStatements 
setupStatement
   setupStatement -> actorAdd 
   setupStatement -> varAssign 
   setupStatement -> comment 
setupStatement+
   setupStatement+ -> setupStatement+ setupStatement 
   setupStatement+ -> setupStatement 
setupStatements  (Nullable) 
   setupStatements -> 
   setupStatements -> setupStatement+ 
test
   test -> == 
   test -> != 
   test -> < 
   test -> > 
   test -> <= 
   test -> >= 
val
   val -> number 
   val -> string 
   val -> stringLit 
var
   var -> string varb 
varAssign
   varAssign -> var = val 
varb  (Nullable) 
   varb -> . string varb 
   varb ->

Here is a sample DRG rotation, not optimal, but it works.

[SETUP]
#sets up an alias for our player
*players+=p1
#sets up an alias for our target
*targets+=t1

#load skills and traits
p1.class=drg

# setup attributes
# nonlisted attributes are assumed to be 0
p1.attr.str=500
p1.attr.dex=200
p1.attr.sks=400

# setup server variables
sim.duration=600
# execute is duration from end of sim
sim.execute=200

# setup diagnostic or no - diagnostic runs 1 run with log output, for testing your rotation
sim.diagnostic=true

# otherwise setup sim trials
sim.trials=10000

# i/o
sim.output="./output.txt"

[PRECAST]
# place a sequential list of ogcd/gcd actions here
# any action that is offensive will begin the sim timer
# however, you may place as many actions as you like
# if you have a set opener rotation you wish to follow, enter it here
# and the [GCD] actionlists will follow once the action queue is complete
(){x_potion,blood_for_blood,heavy_thrust}

[GCD]
# remaining is set to 0 if an aura does not exist
# you do not need to test for both exists and remaining
# if an action is in the queue, no further actions will be run
# if a condition is satisfied, the sim will attempt to cast the action
# if an action succeeds, no further actions will be run until the queue is empty
# the only supported boolean operator is &
# to do | actions, use multiple action lines
(p1.aura.heavy_thrust.remaining<5.0){heavy_thrust}
(t1.aura.chaos_thrust.remaining<12.0){impulse_drive,disembowel,chaos_thrust}
(t1.aura.phlebotomize<5.0){phlebotomize}
(){true_thrust,vorpal_thrust,full_thrust}

[OGCD]
# you'll need this unless you want to constantly clip GCDs
# actionlist execution stops as soon as a successful action is entered
# blank actions are automatically successful
# be very careful queueing oGCDs. They will automatically be run in sequence, without regard for clipping into a gcd
(p1.nextgcd<1.0){}
(){blood_for_blood}
(p1.nextaction==full_thrust){life_surge}
(!p1.cd.jump){power_surge}
(){jump}
(){dragonfire_dive}
(){leg_sweep}
