Ad Support & Multi-line Comment Fix

Changes in this branch

1. Fixed `\n` handling in replies and ads

The bot now properly converts literal \n escape sequences to actual newlines when loading replies from storage/replies.txt and ads from storage/ads.txt. This fixes the issue where the Lolz API couldn't handle multi-line comments properly.

Before: \n was sent as literal text After: \n is converted to actual newline characters

2. Added Ad Support

You can now add advertisements to your bot's comments with configurable probability.

Configuration (`.env`):

# Enable/disable ads (default: false)
ENABLE_ADS=true

# Probability of adding an ad to a comment (0.0 - 1.0, where 1.0 = 100%)
# Default: 0.3 (30% chance)
ADS_PROBABILITY=0.3

Ad File (`storage/ads.txt`):

Create a file storage/ads.txt with your ad content. The file can contain multi-line BBCode:

[ad=align=center][CENTER]PROXYLEET — прокси под работу с аккаунтами и трафиком.
Серверные IPv4 (десятки стран), мобильные, MTProto. От 164 ₽ / 30 дней.
Выдача автоматическая, оплата с баланса лолза.
Промокод LOLZ10 — 10% скидки.

Note: You can use \n in the ad file to create newlines, and it will be converted to actual newlines automatically.

3. How it works

When ENABLE_ADS=true, the bot will randomly add the ad content to comments based on ADS_PROBABILITY
The ad is appended to the comment with a double newline separator (\n\n)
Each comment has an independent chance of including the ad
If the ad file is not found or empty, ads are silently skipped

Example Usage

Without ads:

✓

With ads (30% probability):

✓

[ad=align=center][CENTER]PROXYLEET — прокси под работу с аккаунтами и трафиком.
Серверные IPv4 (десятки стран), мобильные, MTProto. От 164 ₽ / 30 дней.
Выдача автоматическая, оплата с баланса лолза.
Промокод LOLZ10 — 10% скидки.

Migration from main branch

Update your .env file with the new variables (see .env.example)
Create storage/ads.txt with your ad content (optional)
Existing storage/replies.txt will now properly handle \n sequences

Testing

To test the multi-line functionality, you can use \n in your replies:

First line\nSecond line\nThird line

This will now correctly appear as:

First line
Second line
Third line
