# MuteBot

Yet another simple Telegram bot that mutes new members in groups. Support joining by invite links, requests or @ usernames.

It is built upon TDLib C interface using C11.

*It may be the first project actually taking TDLib C interface into production. You can use this project as an example of how to use TDLib C interface.*

## Building

*Why do you need to spend half a hour, gigabytes of memory and gigabytes of disk to build TDLib again? Because TDLib doesn't support dynamic linking.*

```shell
$ mkdir cmake-build-release
$ cd cmake-build-release
$ cmake -DCMAKE_BUILD_TYPE=Release ..
$ make -j mutebot
```

## Usage

Obtain API ID and API Hash from [https://my.telegram.org](https://my.telegram.org).

Obtain a bot token using BotFather.

```
$ export TD_API_ID <Your API ID>
$ export TD_API_HASH <Your API Hash>
$ export TD_BOT_TOKEN <Your Bot Token>
$ ./mutebot
```

Alternatively, you can replace the following environment variables with -i -H and -T command line options, but they are not recommended, because some operating systems expose command line arguments to all users.

### Configuration

Currently, there are only a few options for you:

* `-t`: Use test DC. (Default: false)
* `-d`: Specify TDLib data directory. (Default: `./td_data/`)
* `-l`: Logout of the current bot. See the following section.

### Log out

TDLib treats bots as normal accounts, so you need to log out if you want to change the bot token. You may logout using the `-l` switch. It does nothing except for logging out the current bot session, if any.
