Brooklyn is intended to be a protocol-independent chat-bridge to allow messages forward to and from various chat systems.
It supports Telegram and IRC for now but it's modular.
Brooklyn is written in Java and uses Maven to manage dependencies.
You can import the source in your favorite IDE in order to test it.
In production you should create a .jar and use it.
The application needs a config file.
The default path is /etc/brooklyn/conf.yml but you can define a custom path, passing it as a first parameter (e.g. java -jar brooklyn.jar /new/path).
If you want to automate the process of configuring it on Debian 9 you can use brooklyn-ansible.
It uses log4j2 to log, see log4j2.xml for more infos. Consider using a log4j2-test.xml for debug purposes.
Due to Telegram APIs limit you should create one bot for each telegram-related channel.
Remember to add the bot on each group you want to manage before adding it in your config file.
You should use secure websocket (wss) instead of ws to connect the bot to a server, because messages are sent in plain text.
Remember to add the bot on each channel you want to manage before adding it in your config file.
This is a self-explanatory example of the configuration file.
bots:
tbot:
type: TelegramBot
username: "JhonBot"
password: "blablabla" # The token key
ibot:
type: IRCBot
username: "skynet"
password: "123456" # Optional
host: "url.of.the.host.com"
rbot:
type: RocketChatBot
host: "wss://chat.wikitolearn.org"
username: "username"
password: "password"
channels:
ch1:
bot: ibot
name: "#channelname"
ch2:
bot: tbot
name: "chat-id"
bridges:
-
- ch1
- ch2
webserver:
content-folder: "/var/www/html/"
base-url: "http://localhost/"
db-uri: "jdbc:sqlite:" # You should not specify a path, so the file is temporary.
You need also a webserver (e.g. nginx) to support attachments in protocols like IRC.
Don't forget to add read and write permissions for the content-folder. Otherwise the app won't work.
You should create a Cron job to remove images when you're running out of space.
An example might be
import os
import shutil
from datetime import date
contentFolder = "/var/www/html/" # Folder to clean
maxSizeGB = 4 # Max folder size
nDaysBeforeExpiration = 1
# Get dir size
dirSizeBytes = 0
for dirPath, dirNames, fileName in os.walk(contentFolder):
for f in fileName:
fp = os.path.join(dirPath, f)
dirSizeBytes += os.path.getsize(fp)
# Clean dir if it is too big
maxSizeBytes = maxSizeGB * 1024 * 1024 * 1024;
if dirSizeBytes > maxSizeBytes:
# Iterate through years
nYearsBeforeExpiration = nDaysBeforeExpiration / 30 / 12
for d in os.listdir(contentFolder):
fullDirPath = contentFolder + d
if os.path.isdir(fullDirPath):
if date.today().year - nYearsBeforeExpiration > int(d):
print("Deleting " + fullDirPath)
shutil.rmtree(fullDirPath)
# Iterate through months
nMonthsBeforeExpiration = nDaysBeforeExpiration / 30
yearFolder = contentFolder + str(date.today().year).zfill(4)
for d in os.listdir(yearFolder):
fullDirPath = os.path.join(yearFolder, d)
if os.path.isdir(fullDirPath):
if date.today().month - nMonthsBeforeExpiration > int(d):
print("Deleting " + fullDirPath)
shutil.rmtree(fullDirPath)
# Iterate through days
monthFolder = os.path.join(yearFolder, str(date.today().month).zfill(2))
for d in os.listdir(monthFolder):
fullDirPath = os.path.join(monthFolder, d)
if os.path.isdir(fullDirPath):
if date.today().day - nDaysBeforeExpiration > int(d):
print("Deleting " + fullDirPath)
shutil.rmtree(fullDirPath)
else:
print("Nothing to clean, there is enough space.")This software is released under the GNU AGPL license.
