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

• 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 language.
• File filtering using file masks.

• Go (v1.20 or higher) installed on your Linux system.
• A Telegram bot token obtained by creating a new bot using BotFather.

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

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:

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

Example configuration:

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<name>.*)\\.jpg" # matched groups will be used as tags prefixed by group names
      expr:
        - "(file.Size() > 1024 * 1024) ? 'big' : ''" # tag files bigger than 1 megabyte

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

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

• /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. chown nobody:nogroup
