Telegram bot written in Go that monitors directories for new files and uploads them to chats.

## Features

- Monitors specified directories for new files and uploads them to Telegram chats.
- Supports multiple directories and chats configuration.
- Can add custom tags to uploaded files using plain text tags, regexps, or [expr](https://github.com/antonmedv/expr) language.
- File filtering using file masks.

## Prerequisites

- Go (v1.20 or higher) installed on your Linux system.
- A Telegram bot token obtained by creating a new bot using [BotFather](https://core.telegram.org/bots#how-do-i-create-a-bot).

## Installation

```bash
git clone https://github.com/3cky/telegram-uploader-bot.git
cd telegram-uploader-bot
make install
```

## Configuration

The bot uses a YAML config file set by `-c` or `--config-file` flags. The default config file is "/usr/local/etc/telegram-uploader-bot.cfg".

To use a custom configuration file, run the bot with the `-c` flag followed by the path to your config file:

```bash
telegram-uploader-bot -c /path/to/custom_config.cfg
```

Example configuration:

```yaml
telegram:
token: "my-telegram-bot-token"

uploads:
- directory: "/path/to/watch/dir"
files:
- "*.jpg" # file name match by the mask is case insensitive
document: false # set to true to upload files as documents (without reencoding)
min_size: 0 # min file size limit to upload (default is 0 - no limit)
max_size: 50 MB # max file size limit to upload (default is 50 MB)
chat: 1234567
tags:
plain:
- "work"
- "important"
regexp:
- ".*/(?P.*)\\.jpg" # matched groups will be used as tags prefixed by group names
expr:
- "(file.Size() > 1024 * 1024) ? 'big' : ''" # tag files bigger than 1 megabyte
```

## Docker

You can launch the **telegram-uploader-bot** in Docker container with the following command:

```shell
docker run -d \
--name=telegram-uploader-bot \
-v /path/to/config.cfg:/usr/local/etc/telegram-uploader-bot.cfg \
-v /path/to/watch/dir:/path/to/watch/dir \
3cky/telegram-uploader-bot
```

Where:

- `/path/to/config.cfg`: path to telegram-uploader-bot config file in the local filesystem.
- `/path/to/watch/dir`: directory to monitor by telegram-uploader-bot, must match uploads directory in config file.

Make sure config file and watched directory are readable by user `nobody`:`nogroup`.
