Let's Play Mafia!
The example code didn't worked for me, I use Python 3, so I changed the main.py file to make it work.
So here is my fixed version for Python 3, I never programmed in Python before so maybe it is a horrible code but it is works :)
run.sh:
#!/bin/bash
./randy.py < from_server > to_server
randy.py:
#!/usr/bin/env python3
import random
with open('players') as f:
p = f.read().split() + ['no one']
with open('from_server') as f:
fs = f.read().split()
msg = ""
day = True
try:
line = fs[0]
if line.endswith(('?', 'victim.')):
day = False
if not day:
msg = (random.choice(p))
else:
if random.random() > 0.5:
if random.random() > 0.5:
msg = ('vote {}'.format(random.choice(p)))
else:
id = random.randint(0, 17)
msg = ('say {}{}'.format(id, (' ' + random.choice(p)) if id > 4 else ''))
with open('to_server', 'w') as f:
f.write(msg)
print(msg)
except: pass
A few thing I learned while I made this work (and it was not clear for me in the description)
printdoes not do anything with the game it is like aconsole.login jsinput()blocks the program running it can be good for step by step debuggingfrom_serverandto_serveris cleared every round.- It is impossible to stop the script with
Ctrl+Ccombination, which is annoying.

Fancy, long bunch of python code that I'm not going to explain (although it isn't golfed), other than that it keeps lists of "friends" and "enemies" that are originally populated based on chance and/or cop investigation. Warning: do not lie in the logician's presence.
Survivalist (v 1.0)
Synopsis
Survivalist simply brutally survives the game by berating anyone that dares to accuse him, regardless of whether he is mafia or not.
Logic
If you survive to the end of the game, you win no matter what. Therefore, you survive at all costs.
Backstory
The troops marched through the dark, damp forest.
"Lieutenant, where are we marching?" The young recruit apparently hadn't hardened himself to atrocities, the commander thought. Oh well. He answered with a brusque "to destroy the enemy".
At the village, the enemy commander was drinking and laughing along with the other officers at the club when a scout rushed in with the news. "There's a column, several hundred yards long, marching through the Yulin forest for us! Rally the troops!"
The enemy commander, obviously inebriated, said unexpectedly, "I've had no reports from other scouts." The scout (later Survivalist) thought, then I'll have to rally the troops myself. After telling the story to the fellow scouts, they came back together, all saying that they had seen enemy troops. The commander still did not believe, saying, "I am ordering you to discontinue scouting. There are no enemy troops".
The scouts decided to get their weapons to save the community. They managed to get to their positions just as the enemy arrived in the village in force. "CHARGE!" yelled the commander of the ambush. "BURN THE HOUSES! BURN THE HOUSES! KILL EVERYONE, INCLUDING THE WOMEN AND THE CHILDREN!"
The scouts saved their entire army. They expected promotion, awards, and medals. Instead, they got a rigged court-martial for mutiny, conviction, 10 years in prison, dishonorable discharge from the military and exile.
There is an old elder at the city council of Salem, Massachusetts. Legend has it that he founded the town. When you meet him in his isolated cottage out in the forest, don't let the twinkle in his eye make you think he's peaceful. If you accuse him, he will ruin you in front of the town.
The Veteran laughed in the darkness. Afraid of the dark, no way. Afraid of monsters under the bed? The man with his hand on trigger of a gun laughed nervously. He wasn't scared of anything, he had told himself. Sure, he was a past war time hero, but he was so used to ambushes and life threatening situations that it made the man simply neurotic. His trigger finger twitched at simple shadows; his heartbeat quickened with every little sound. Yes, he was this scared of death. How could he not, seeing so many people die in horrible ways? All he knew from being kidnapped and miraculously escaping his enemies was that there was no mercy.
