Telegram-purple is a Libpurple plugin that adds support for the Telegram messenger.

- update to libtgl 2
- support two-factor authentication
- improve sticker support
- add option to control message read recipes
- many bugfixes

If you migrate from an older version, the Telegram authentication files have been moved to .purple/telegram-purple. If you want to keep your old secret chats, please copy it manually from ~/.telegram-purple, otherwise you will be prompted for a new SMS code.

Below, you will find instructions on how to build the libpurple protocol plugin. If you just want to use the plugin in Adium, download precompiled packages here..

This repository has submodules, so you need to clone recursively.

    git clone --recursive https://github.com/majn/telegram-purple
    cd telegram-purple

    sudo yum install gcc openssl-devel glib2-devel libpurple-devel libwebp-devel

    sudo apt-get install libssl-dev libglib2.0-dev libpurple-dev libwebp-dev

    sudo zypper install gcc glib glib-devel libpurple libpurple-devel zlib-devel openssl libopenssl-devel libwebp-devel

If libwebp is not available, you can disable sticker support by calling ./configure --disable-libweb instead.

    ./configure
    make
    sudo make install

This repository contains submodules and just a simple pull won't be enough to update all submodule files. Pull new changes with:

    git pull
    git submodule update --recursive

The username is your current phone number, including your full country prefix. For Germany, this would be '+49', resulting in a user name like '+49151123456'. Telegram will verify your phone number by sending you a code via sms. You will be prompted for this code, once that happens.

You can use Telegram secret chats with this plugin, they will show up as a new buddy with a '!' in front of the buddy name.

One caveat of secret chats in Telegram is that they can only have one endpoint, this is a limitation of the protocol. This means that if you create a secret chat in Pidgin you will not be able to use that chat on your phone. You will be asked whether to accept each secret chat, so you can always choose to accept the chat on a different device if you want. You can set a default behavior for dealing with secret chats (Accept or Decline) in the account settings if you don't want that prompt to appear every time.

Self destructive messages will be ignored, since I don't know any way to delete them from the conversation and the history.

Click on the buddy in the buddy list and click on "Show Info" to visualize the key fingerprint.

To initiate a secret chat from Pidgin, click on a Buddy in the Buddy List and hit ``Start Secret Chat''

If you delete a secret chat from the buddy list, it will be terminated and no longer be usable.

The Telegram phone applications for iOS and Android make use of standardized Unicode smileys (called Emojis). Pidgin does not display those smileys natively, but you can install a custom smiley theme like (https://github.com/stv0g/unicode-emoji) or (https://github.com/VxJasonxV/emoji-for-pidgin) and activate it under Settings > Themes > Smiley Theme.

If you encounter problems running this plugin and you have updated from an older version, deleting your old user-data might be helpful. WARNING: This will require you to enter a new authentication code and delete all your secret chat keys.

To clean all your user files run:

    make purge

Compiling with XCode is a little bit problematic, since it requries you to compile Adium first to get the necessary framework files. My advice is to just use the prebuild bundle, but if you really want to do it, follow those steps.

1. Get the Adium source, compile it with XCode and copy the build output into telegram-adium/Frameworks/Adium. It should contain at least Adium.framework, AdiumLibpurple.framework and AIUitilies.framework

2. Open the Adium source code, go to ./Frameworks and copy libglib.framework and libpurple.framework into telegram-adium/Frameworks/Adium

3. Build the tgl submodule and delete libtgl.so from libs/ (it should only contain libtgl.a)

4. Install libwebp with homebrew, move into copy it into your project

   brew install webp cp /usr/local/Cellar/webp/0.4.3/lib/libwebp.a ./telegram-adium/Frameworks/

5. Build the XCode-Project and execute the created bundle
