## Telegram messenger CLI [![Build Status](https://travis-ci.org/vysheng/tg.png)](https://travis-ci.org/vysheng/tg)
Command-line interface for [Telegram](http://telegram.org). Uses readline interface.
### API, Protocol documentation
Documentation for Telegram API is available here: http://core.telegram.org/api
Documentation for MTproto protocol is available here: http://core.telegram.org/mtproto
### 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 and BSDs
Install libs: readline or libedit, 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
On FreeBSD:
pkg install libconfig libexecinfo lua52
On OpenBSD:
pkg_add libconfig libexecinfo lua
Then,
./configure
make
#### Mac OS X
The client depends on [readline library](http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html) and [libconfig](http://www.hyperrealm.com/libconfig/), which are not included in OS X by default. You have to install these libraries manually, e.g. using [Homebrew](http://brew.sh/).
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](https://github.com/vysheng/tg/issues/3#issuecomment-28293731) for this solution.
Install these ports:
* devel/libconfig
* devel/libexecinfo
* lang/lua52
Then build:
env CC=clang CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib LUA=/usr/local/bin/lua52 LUA_INCLUDE=-I/usr/local/include/lua52 LUA_LIB=-llua-5.2 ./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-server.pub or in /etc/telegram/server.pub, if it's not, specify where to find it:
./telegram -k tg-server.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 <underscore> 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> <underscore> Name <underscore> Lastname with all spaces changed to underscores.
If two or more peers have same name, <sharp>number is appended to the name. (for example A_B, A_B#1, A_B#2 and so on)
