Installation

Clone GitHub Repository

$ git clone https://github.com/vysheng/tg.git && cd tg

or download and extract zip

$ wget https://github.com/vysheng/tg/archive/master.zip -O tg-master.zip
$ unzip tg-master.zip && cd tg-master

Linux

Install libs: readline openssl and (if you want to use config) libconfig and liblua. If you do not want to use them pass options --disable-libconfig and --disable-liblua respectively On ubuntu use:

$ sudo apt-get install libreadline-dev libconfig-dev libssl-dev lua5.2 liblua5.2-dev

On gentoo:

$ sudo emerge -av sys-libs/readline dev-libs/libconfig dev-libs/openssl dev-lang/lua

On Fedora:

$ sudo yum install lua-devel openssl-devel libconfig-devel readline-devel

Default Makefile uses liblua5.2 from ubuntu. If you use different version of liblua or linux you have to run ./configure script or you will get some strange compilation error.

Then

$ ./configure
$ make

Mac OS X

The client depends on readline library and libconfig, which are not included in OS X by default. You have to install these libraries manually, e.g. using Homebrew.

$ brew install libconfig
$ brew install readline
$ brew install lua
$ export CFLAGS="-I/usr/local/include -I/usr/local/Cellar/readline/6.2.4/include"
$ export LDFLAGS="-L/usr/local/lib -L/usr/local/Cellar/readline/6.2.4/lib"
$ ./configure && make

Thanks to @jfontan for this solution.

FreeBSD

Install these ports:

• devel/libconfig
• devel/libexecinfo

Then build:

$ env CC=clang CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib ./configure
$ make

Other UNIX

If you manage to launch it on other UNIX, please let me know.

Usage

./telegram -k <public-server-key>

By default public key is stored in the same folder named tg.pub or in /etc/telegram/server.pub, if it's not, specify where to find it:

./telegram -k tg.pub

Client support TAB completion and command history.

Peer refers to the name of the contact or dialog and can be accessed by TAB completion. For user contacts peer name is Name Lastname with all spaces changed to underscores. For chats it is it's title with all spaces changed to underscores For encrypted chats it is <Exсlamation mark> Name Lastname with all spaces changed to underscores.

If two or more peers have same name, number is appended to the name. (for example A_B, A_B#1, A_B#2 and so on)
